Answer:

C. Multiply 1st equation by 3, then add together

Step-by-step explanation:

X+y=10

3(x+y)=3(10)multiply by 3

3x+3y=30 add to following equation

2x-3y=6

5x=36

Answer:

3 * (½*2*5) = x

Step-by-step explanation:

Cost of carpeting = $3 per square foot

We have a triangular section to cover having the following dimensions:

base = 2 yd

height = 5 yd

First, let's find the area of the section = area of triangle

Area of triangle = ½*base*height

Area of the triangular section of the floor = ½*2*5

If $3 will cover 1 ft², therefore,

x will cover ½*2*5

Thus:

3 * (½*2*5) = x

The answer is -3, hope this helps!

Answer:

12-1/2- -4-1/2

Step-by-step explanation:

After 3 months, the tree will reach a height of 12 feet.

Imagine you plant a tree that is initially 6 feet tall. Every month, it grows by 2 feet.

Let's denote the height of the tree at the start as H₀ = 6 feet. Since the tree grows 2 feet each month, we can express its growth rate as "2 feet per month." To calculate how tall it will be over time, we need to consider the number of months it has been growing.

After 1 month, the height of the tree will be:

H₁ = H₀ + (growth rate * number of months) = 6 + (2 * 1) = 8 feet.

After 2 months, the height of the tree will be:

H₂ = H₀ + (growth rate * number of months) = 6 + (2 * 2) = 10 feet.

After 3 months, the height of the tree will be:

H₃ = H₀ + (growth rate * number of months) = 6 + (2 * 3) = 12 feet.

So, after 3 months, the tree will be 12 feet tall.

We can also represent this growth pattern using a mathematical equation. Let "t" be the number of months the tree has been growing, and "Hₜ" be its height at time "t."

The equation for the height of the tree over time is given by:

Hₜ = H₀ + (growth rate * t).

Using this equation, you can plug in the value of "t" as 3 to find the height after 3 months:

H₃ = 6 + (2 * 3) = 12 feet.

In conclusion, the tree will keep growing 2 feet every month, and you can find its height at any given time using the formula Hₜ = H₀ + (growth rate * t). After 3 months, the tree will reach a height of 12 feet.

The requried width of the crossbar for the H is 3.96 ft.

In a right-angled triangle, its sides, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,

Let, from the figure,
b = 5

c = 1/2*6= 3
e = 1/2*b = 1/2*5 = 2.5

a = √[c²-e²]

a = √[3²-2.25²]

a = √9-5.0625

a = 1.98

x = 2a = 2*1.98=3.96

Thus, the requried width of the crossbar for the H is 3.96 ft.

Answer:

Function B > Function A > Function C

Step-by-step explanation:

For function A,

From the given table,

Two points are (3, 3) and (5, 7).

Rate of change of the function between these points = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                                                                                         = [tex]\frac{7-3}{5-3}[/tex]

                                                                                         = 2

For function B,

Rate of change = [tex]\frac{\triangle y}{\triangle x}[/tex]

Here, Δy = y-intercept = 3

And Δx = x-intercept = -5

Therefore, rate of change = [tex]\frac{3}{-5}[/tex]

                                            = -0.6

For function C,

Equation of the line → y = 3x + 1

By comparing this equation with slope-intercept form of the equation,

y = mx + b

Slope of the line = m = 3

Rate of change = 3

Now we can write the rate of changes of each function from least to greatest.

-0.6 > 2 > 3

Function B > Function A > Function C

Answer:

The probability that all 4 units are good is 10.66%.

Step-by-step explanation:

Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:

14 - 6 = 8

8/14 x 8/14 x 8/14 x 8/14 = X

0.5714 x 0.5714 x 0.5714 x 0.5714 = X

0.1066 = X

0.1066 x 100 = 10.66

Therefore, the probability that all 4 units are good is 10.66%.

Answer:

4

Step-by-step explanation:

The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.

Example, the degree of 4x^8 is 8.

So the degree of 5x^4 is 4.

The degree of 3x^2 is 2.

The degree of 1 is 0 since there is no variable in this expression.

So the degree of 5 x^4 + 3 x^2 + 1 is 4.

Step-by-step explanation:

let the smaller number be x

5x - x = 52

4x = 52

4x÷4 = 52÷4

x = 13

the smaller number is 13

the bigger number is 5×13 = 65

Answer: [tex]254.94\ ft[/tex]

Step-by-step explanation:

Given

Building A is 490 feet tall and building B is 754 ft tall.

If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]

Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]

If the difference between them is [tex]x[/tex]

From the figure, we can write

[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]

Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.
