Answer:

Radius, x = 80.6mm

Step-by-step explanation:

[tex]radius =\sqrt{height^2 -slant\ height^2} = \sqrt{90^2 - 40^2} = \sqrt{8100-1600} =\sqrt{6500}[/tex]

Radius = 80.6mm

5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.

3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.

Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is

(3 L) / (8 L) = 0.375 = 37.5%

===========================================================

Explanation:

The diagram shows that PT = 4 and QR = 5. Since QR is a radius of the circle, this means that the other radii segments TR and RS are also 5 units long.

Note how PR = PT+TR = 4+5 = 9, and how this segment is the hypotenuse for the right triangles PQR and PRS.

Picking either triangle, we have one known leg of 5 units (the radius mentioned earlier) and the other is unknown. The unknown leg is tangent to the circle, and recall that a tangent segment is always perpendicular to the radius at the point of tangency. So that's why we have right triangles.

Apply the pythagorean theorem to find the length of PQ and PS (both are the same length)

a^2 + b^2 = c^2

a^2 + 5^2 = 9^2

a^2 + 25 = 81

a^2 = 81 - 25

a^2 = 56

a = sqrt(56)

a = sqrt(4*14)

a = sqrt(4)*sqrt(14)

a = 2*sqrt(14)

The exact length of PQ and PS is 2*sqrt(14) units.

---------

We have enough to find the perimeter of quadrilateral PQRS. We add up the exterior sides. That means we ignore the interior segment PR.

perimeter = PQ+QR+RS+SP

perimeter = 2*sqrt(14)+5+5+2*sqrt(14)

perimeter = 10+4*sqrt(14)

Answer is choice B

Side note: The expression above approximates to roughly 24.966629

x = -1.9/2.1

x = -0.9047619048

As the number or the magnitude of x is a terminating decimal number so it is not irrational number its a rational number

Answer: 51 students

Step-by-step explanation:

There are 600 students in this school and 34% are in 8th Grade.

The number of students in 8th grade is:

= 34% * 600

= 204 students

Then out of these 204, 1/4 walk to school. The number of students walking to school is therefore:

= 204 * 1/4

= 51 students

Answer:

1 pizza

Step-by-step explanation:

Of the pizzas recently sold at Pizza Pies, 10 had pepperoni and 2 did not.

This means, the total number of pizzas sold is

10 pepperoni + 2 pizzas without pepperoni = 12 pizzas

Hence, the number of 6 pizzas that would be sold without pepperoni is calculated as:

From the above question,

12 pizzas = 2 pizza without pepperoni

6 pizzas = x

Cross Multiply

12 pizzas × x = 6 Pizzas × 2 pizza without pepperoni

x = 6 Pizzas × 2 pizza without pepperoni/12 pizzas

x = 1 pizza without pepperoni

Therefore, 1 pizza would not have pepperoni out of 6 pizzas sold

Answer:

A

Step-by-step explanation:

Here the base (3.2) is greater than 1 and the exponent (t) is positive.  Thus the graph will have shape A.

The correct graph for the given function h(t)=0.6×[tex]3.2^{t}[/tex] will be upward increasing so option (A) will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given function is  h(t)=0.6×[tex]3.2^{t}[/tex]

As t is increasing then the term [tex]3.2^{t}[/tex]  will also go to increase since 3.2 is greater than 1.

Hence the value of the graph will go to increase as x increases so it is clear that option (A) will be correct.

Answer:

640

Step-by-step explanation:

5% of 400 is 20

20 x 12 is 240

400 + 240 = 640

Forgive me if I'm wrong. I suck at math XD

The amount for the month of December is $640.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Gabriel deposits $400 into a savings account in January If he deposits 5% more each month.

The December month deposit is calculated as,

5% of 400 is 20

20 x 12 is 240

400 + 240 = $640

Therefore, the amount for the month of December is $640.

Answer:

-1/√2  

Step-by-step explanation:

According to trigonometry identity

cos(A+B) = cosAcosB - sinA sinB

Given the expression

(cos92°)(cos133°)-(sin92°)(sin133°)

This can be expressed as cos(92+133) where A = 92, B = 133

(cos92°)(cos133°)-(sin92°)(sin133°)

= cos(92+133)

= cos225

= -0.7071

= -1/√2

Hence the exact value is  -1/√2  

Answer:

508sq. cm

Step-by-step explanation:

surface area of a prism = 2(lw + wh + lh)

For the larger prism

Surface area = 2(2*10 + 2 * 12 * 10*12)

Surface area = 2(20+24+120)

Surface area = 2(164)

Surface area = 328sq.cm

For the smaller prism

Surface area = 2(3*6 + 3 * 8 * 6*8)

Surface area = 2(18+24+48)

Surface area = 2(90)

Surface area = 180 sq.cm

Surface area of the figure = 328 + 180

Surface area of the figure = 508sq. cm

Answer:

Wanda's recipe needs 0.09 more cups of flour per bagel.

Step-by-step explanation:

First, you have to find the amount flour that each of them need for one bagel by dividing the cups of flour they use by the number of bagels:

Wanda: 3.54/6= 0.59 cups of flour

Eli: 2.5/5=0.5 cups of flour

Now, you have to subtract the amount of flour Eli needs from the amount that Wanda needs:

0.59-0.5=0.09

According to thiss, the answer is that Wanda's recipe needs 0.09 more cups of flour per bagel.

The answer of the condition is Fail to Reject.

A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test that is valid to perform when the test statistic is chi-squared distributed under the null hypothesis, specifically Pearson's chi-squared test and variants thereof. Pearson's chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table.

The data is given as follow:

The experimental weight of cashews = 40 % of 20lbs

                                                                  = 8

The experimental weight of Brazil Nuts = 15 % of 20lbs

                                                                  = 3

The experimental weight of Almonds = 20 % of 20lbs

                                                                 = 4

The experimental weight of peanuts = 25 % of 20lbs

                                                                  = 5

Answer:

130 ; 50% ; 25%

Step-by-step explanation:

Using te boxplot to answer the underlying questions :

Number of employees who spend $10 or less corresponds to the lower quartile, which is up to 25% of the distribution :

Total number of employees = 520

Number of employees who spend $10 or less = 25% of 520 = 0.25 * 520 = 130 employees.

Percentage of employees who spend from $10 to $45 = Interquartile range

$10 corresponds to lower quartile = 25%

$45 corresponds to upper quartile = 75%

IQR  = 75% - 25% = 50%

Percentage who spend $45 or more

$45 corresponds to the upper QUARTILE (Q3) :

45 or more = 100% - Q3 = 100% - 75% = 25%

The answer is 152 r10

Step-by-step explanation:

There is indeed a remainder when dividing 6394 by 42.

6394 ÷ 42 = 152 with a remainder of 10, so, the remainder is 10.

Here, we have,

To determine if there is a remainder when dividing 6394 by 42,

we can perform the division and check if the result is a whole number or a decimal.

6394 ÷ 42 = 152 with a remainder of 10

Since the division does not result in a whole number,

but rather a quotient of 152 with a remainder of 10,

it indicates that there is indeed a remainder when dividing 6394 by 42.
