Answer:

x ≈ 36.2

Step-by-step explanation:

the segment from the vertex of the triangle to the base is a perpendicular bisector, then

consider the right triangle on the right with legs 15 and 33 , hypotenuse x

using Pythagoras' identity in the right triangle

x² = 15² + 33² = 225 + 1089 = 1314 ( take square root of both sides )

x = [tex]\sqrt{1314}[/tex] ≈ 36.2 ( to the nearest tenth )

Answer:

36.2

Step-by-step explanation:

The tick marks on the two sides of the triangle indicate that the sides are of equal length. Therefore, as the triangle has two sides of equal length, it is an isosceles triangle.

In an isosceles triangle, the altitude is the perpendicular bisector of the base. Therefore, the triangle is made up of two congruent right triangles with:

To calculate the value of x, we can use Pythagoras Theorem:

[tex]\boxed{a^2+b^2=c^2}[/tex]

where:

Substitute the values into the formula and solve for x:

[tex]\implies 15^2+33^2=x^2[/tex]

[tex]\implies 225+1089=x^2[/tex]

[tex]\implies 1314=x^2[/tex]

[tex]\implies x^2=1314[/tex]

[tex]\implies \sqrt{x^2}=\sqrt{1314}[/tex]

[tex]\implies x=36.2491379...[/tex]

[tex]\implies x=36.2\; \rm (nearest\;tenth)[/tex]

Therefore, the value of x is 36.2 units (nearest tenth).

The value of the equation in terms of x is x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex].

Given is an equation, y = 3√(x²+2)15, we need to convert it in terms of x,

So,

y = 3√(x²+2) 15​

Squaring both sides,

y² = 9 [(x²+2)15]

y² = 9 [15x²+30]

y² = 135x²+270

y²-270 = 135x²

y²-270 / 135 = x²

x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex]

Hence, the value of the equation in terms of x is x = [tex]\sqrt{\frac{y^2-270}{135}}[/tex].

There are two sectors that are factors of 3:

So out of the 10 sectors, there is a 2/10 probability that the randomly selected point lies in one of these three sectors.

Therefore, the probability is 0.2 or 20%.

Answer:

20%

Step-by-step explanation:

For this question, we must find the numbers from 1-10 that are factors of 3. A factor is a number that, when multiplied by a specific number, gives a specific whole. For instance, in 2*4=8, 2 and 4 would be factors. The number 3 only has two factors: one and itself. Since two of the ten numbers are factors of 3, that is a rate of 2/10, 0.2, or 20%.

To estimate the water flow rate in the pipe, we need to measure the velocity at two radial locations and then use the integral formula to calculate the flow rate. The formula tells us that the flow rate is equal to the integral of 2πrv with respect to r, where r is the radial location, v is the velocity, and the limits of integration are 0 to 2 (since the pipe has a radius of 2m).

Since we don't know how the velocity varies along the radial location, we need to choose two locations that will give us the most accurate estimate of the flow rate. The best locations to choose are where the velocity varies the most, which is usually near the center and near the edge of the pipe.

Based on this, the two radial locations that would give us the most accurate calculation of the flow rate are 0.42 and 1.58. These locations are close to the center and the edge of the pipe, respectively, and will give us a good estimate of how the velocity varies along the radial location.

Therefore, the answer is 0.42, 1.58.

The MSwithin treatments for this analysis is 2.

In analysis of variance (ANOVA), we partition the total variation in a set of data into two types of variation: variation within groups and variation between groups. This partitioning helps us to test whether the means of the groups are significantly different from each other or not.

The formula for calculating the mean square within treatments (MSW) is:

MSW = SSW / dfW

where SSW is the sum of squares within treatments and dfW is the degrees of freedom associated with the SSW.

To calculate MSW, we first need to calculate dfW, which is equal to the total number of observations minus the total number of groups. In this case, there are 4 groups, each with 5 observations, so there are a total of 20 observations:

dfW = 20 - 4 = 16

Next, we can use the given SSwithin treatments value of 32 to calculate SSW:

SSW = 32

Finally, we can plug in the values we have calculated to find MSW:

MSW = SSW / dfW

MSW = 32 / 16

MSW = 2

Therefore, the MSwithin treatments for this analysis is 2.

In most countries, including the United States, income tax is a tax imposed on an individual's income by the government. The amount of income tax paid typically depends on the amount of income earned and any deductions or credits that apply to the individual's tax situation.

A typical pay stub includes information such as the employee's gross pay (the amount earned before any deductions), the net pay (the amount received after deductions), and various taxes and deductions taken out of the employee's pay, such as federal income tax, state income tax, Social Security tax, and Medicare tax.

To complete the missing pieces on a pay stub, you will need to know the employee's gross pay and any deductions that apply to their tax situation. The amount of income tax withheld from an employee's pay depends on several factors, including their tax bracket, filing status, and any exemptions or deductions they are eligible for.

It's important to note that tax laws and regulations vary by country and even by state or province within a country, so the specific rules and calculations for income tax can differ depending on your location.

The probability of Shenanigans selling a Peanut Butter Cup cone next is approximately 31.22%.

To calculate the probability of Shenanigans selling a Peanut Butter Cup cone next, we need to determine the number of cones sold that were not Peanut Butter Cup cones and divide that by the total number of cones sold.

Given that Shenanigans sold a total of 711 ice cream cones last week and 489 of those were either Coffee Cream or Oreo, we can subtract 489 from 711 to find the number of cones that were not Coffee Cream or Oreo;

Number of cones that were not Coffee Cream or Oreo = 711 - 489 = 222

So, out of the total 711 cones sold, 222 were not Coffee Cream or Oreo cones. Therefore, the remaining cones must be Peanut Butter Cup cones.

Now, we can calculate the probability of selling a Peanut Butter Cup cone next by dividing the number of Peanut Butter Cup cones by the total number of cones sold, and then multiplying by 100 to find the result as a percentage;

Probability of selling a Peanut Butter Cup cone next = (Number of Peanut Butter Cup cones / Total number of cones sold) × 100

Probability of selling a Peanut Butter Cup cone next = (222 / 711) × 100

Answer: A, C, and F

Step-by-step explanation:

v=1/3 x B(not b to get B do bxb)xh

V=1/3(19x19)(5)=1/3(361)(5)=1/3(1805)

1805/3=601.7^3

Frido has V=4873.5

601.7x8.1=4873.5

8.1 as a percent is 8.1x100=810%

So the answers are

A.

Ricardo’s pyramid has a volume of 601.7 in^3.

C.

Frido’s pyramid is 8.1 times larger than Ricardo’s.

F.

Frido’s pyramid is 810% larger than Ricardo’s.

The only correct statements are:

Ricardo’s pyramid has a volume of 601.7 in³.

Frido’s pyramid is 8.1 times larger than Ricardo’s.

Options A and C are the correct answer.

We have,

The volumes of square pyramids.

V = (1/3) x s² x h

For Ricardo's pyramid,

s = 19 inches

h = 5 inches.

Substituting these values into the formula, we get:

V = (1/3) x 19² x 5

V ≈ 601.7 in³

Therefore, statement A is correct.

We do not have enough information to determine the volume of Frido's pyramid directly using the given formula.

However, we can use the fact that the volume of a pyramid is proportional to the cube of its linear dimensions (i.e., the length of its sides).

So if Frido's pyramid has a volume that is k times larger than Ricardo's, then the ratio of their corresponding linear dimensions (i.e., side lengths) will be:

(k)^(1/3)

Using this information, we can compare the volumes of the two pyramids:

Frido's pyramid / Ricardo's pyramid = k

(Frido's pyramid / Ricardo's pyramid)^(1/3) = (k)^(1/3)

We are given that Frido's pyramid has a volume of 4873.5 in³.

so,

k = Frido's pyramid / Ricardo's pyramid

k = 4873.5 / 601.7

k = 8.1

Therefore, statement C is correct.

We can also use this value of k to compare the sizes of the two pyramids in other ways:

Frido's pyramid is 7.1 times larger than Ricardo's (k - 1 = 8.1 - 1 = 7.1).

so statement D is incorrect.

Frido's pyramid is approximately 80.5% larger than Ricardo's.

[(k - 1) x 100%

= (8.1 - 1) x 100%

= 750%,

so statement E is incorrect.

Frido's pyramid is approximately 710% larger than Ricardo's

= k x 100%

= 810%

so statement F is incorrect.

Therefore,

The only correct statements are:

Ricardo’s pyramid has a volume of 601.7 in³.

Frido’s pyramid is 8.1 times larger than Ricardo’s.

The cook made 9 servings of baked beans.

We have,

To find the number of servings of beans, we need to divide the total amount of baked beans by the number of baked beans per serving.

Total amount of baked beans = 7 1/2 pints

Amount of baked beans per serving = 5/6 pint

Number of servings of beans = (7 1/2) ÷ (5/6)

Converting 7 1/2 to an improper fraction:

7 1/2 = (2 × 7) + 1 = 15/2

Number of servings of beans = (15/2) ÷ (5/6)

To divide fractions, we can multiply by the reciprocal of the divisor:

Number of servings of beans = (15/2) × (6/5)

Number of servings of beans = 45/5

Number of servings of beans = 9

True. A counter variable is often used in loops to track the number of times the loop has executed.

In programming, a counter variable is a variable that is used to keep track of the number of times a loop has executed. A counter variable is usually initialized to a starting value, and then incremented or decremented with each iteration of the loop. The loop continues to execute as long as the counter variable meets certain conditions.

The purpose of a counter variable is to allow a loop to repeat a specific number of times. For example, if you want to repeat a block of code 10 times, you can set a counter variable to 0, and then use a loop to execute the code until the counter variable reaches 10.

Counter variables are commonly used in programming languages that support loops, such as C++, Java, Python, and JavaScript. They provide a simple and effective way to repeat code without having to write the same statements over and over again.

The continuous-time convolution integral of y(t) is [tex]$y(t) = k e^{-yt} u(t) * (u(t+2)-u(t))$[/tex].

To evaluate this convolution integral, we first need to express the integrand as a piecewise function. Since u(t) is 1 for t >= 0 and 0 for t < 0, we can rewrite u(t+2)-u(t) as a piecewise function:

u(t+2)-u(t) =

1, 0 <= t < 2

0, t >= 2

0, t < 0

Now we can evaluate the convolution integral using the definition:

y(t) = ∫[tex]_0^t[/tex] x(τ)h(t-τ)dτ

Substituting the given functions for x(t) and h(t) and simplifying using the piecewise function for u(t+2)-u(t), we get:

The equation obtained by taking the Laplace transform of the given initial value problem is:

Y = [5 / ([tex]s^2[/tex] + 25) - 2s - 7] / (s^2 - 25)

To solve the given initial value problem using Laplace transform, we first take the Laplace transform of both sides of the differential equation:

L[y"] - 7L[y] - 18L[y] = L[sin(5t)]

Using the properties of Laplace transform, we have:

[tex]s^2[/tex] Y - s y(0) - y'(0) - 7Y - 18Y = 5 / (s^2 + 25)

Substituting the initial conditions y(0) = -2 and y'(0) = 7, we get:

s^2 Y + 2s + 7 - 7Y - 18Y = 5 / (s^2 + 25)

Simplifying this equation, we get:

s^2 Y - 25Y = 5 / (s^2 + 25) - 2s - 7

Now we can solve for Y:

Y = [5 / (s^2 + 25) - 2s - 7] / (s^2 - 25)

We can use partial fraction decomposition to simplify the expression further:

Y = [A s + B] / (s + 5) + [C s + D] / (s - 5) - (2s + 7) / (s^2 + 25)

Multiplying both sides by the denominator (s^2 - 25), we get:

[tex]As^3 + Bs^2 - 5As^2 - 5Bs + Cs^3 - Ds^2 - 5Cs + 5D - (2s + 7)(s^2 - 25) = 5[/tex]

Simplifying and equating the coefficients of the like powers of s on both sides, we get:

A + C = 0

B - 5A - D + 50 = 0

5B - 5C - 2 = 0

Solving these equations, we get:

A = -C

B = 20/9

C = -20/9

D = -7/9

Substituting these values, we get:

Y = [-20s/9 - 20/9] / (s + 5) + [20s/9 + 7/9] / (s - 5) - (2s + 7) / (s^2 + 25)

Taking the inverse Laplace transform, we get the solution y(t):

y(t) = [-20/9 exp(-5t) - 20/9] + [20/9 exp(5t) + 7/9] cos(5t) - (2/5) sin(5t)

Therefore, the equation obtained by taking the Laplace transform of the given initial value problem is:
