Step-by-step explanation:

the 3rd angle is 60 degrees

as it is an equalateral triangle, all the sides are equal. So we can say that

7x + 19 = 11x - 89

89 + 19 = 11x-7x

108 = 4x

x = 108/4

x = 27

What is the product of 60?

Answers

We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2.

Answer:

the product of 60 is 5×3×2×2

Compare the estimates to the exact perimeter.

The estimate using measurements rounded to the nearest whole number is closer to the exact perimeter.

The estimate using measurements rounded to the nearest tenth is closer to the exact perimeter.

The two estimates are equally close to the exact perimeter.

Neither estimate is close enough to the exact perimeter to be useful.

Answers

Answer:

27!

Step-by-step explanation:

Heya! Considering that the question has already given you the values of x and y, all you are left to do is plug them back into the equation. The value of 6 multiplied by x- 5- gets you to 30. Since y is equal to 1, 3 multiplied by 1 gets you 3. 30-3 gets you to 27, so that is your answer. I hope this helped! (Please mark as branliest if I did happen to get this right. <3)

Answer:

Step-by-step explanation:

10, 000 2,500

20, 000 3,000

30, 000 3, 500

Taking two points (10000, 2500) and (20000, 3000) to find the slope between the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{3000-2500}{20000-10000}[/tex]

[tex]m=\frac{1}{20}[/tex]

[tex]m=0.05[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where 'm' is the slope and 'b' is the y-intercept

substituting the point (10000, 2500) and m=0.05 in the slope-intercept form

[tex]y=mx+b[/tex]

[tex]2500\:=\:0.05\left(10000\right)+b[/tex]

[tex]500+b=2500[/tex]

[tex]b=2000[/tex]

Thus, the y-intercept is: b=2000

Thus,

slope = 0.05, y-intercept = 2,000

Hence, option A is true.

Write an equation of the parabola that passes through the point (62,−490) and has x-intercepts −8 and 72. Then find the average rate of change from x=−8 to x=2.

Answers

Answer:

y = 0.7(x^2 - 64x - 576)

Average rate of change = -49.

Step-by-step explanation:

As the x intercepts are -8 and 72 we can write the equation

y = a(x + 8)(x - 72) where a is some constant to be found.

As it passes through point (62, -490) we have, substituting:

-490 = a(62+8)(62-72)

-490 = - 700a

a = 0.7

So the equation of the parabola

y = 0.7(x + 8)(x - 72) or

y = 0.7(x^2 - 64x - 576).

Average rate of change between x = -8 and x = 2

= [0.7(2+ 8)(2 - 72) - 0.7(-8+8)(-8-72)] / (2 - -8)

= -490 - 0 /10

= -49

Answers

Answer:

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Step-by-step explanation:

Given

Stores and Parking Lots

Required

Determine the area as a sum of area of stores and area of parking lots

First, calculate the area of the stores

The dimension of store A is: 25 by 10

The dimension of store B is: 25 by w

The dimension of stores A and B (as an entity) is: 25 by 10 + w

The area is then calculated as:

[tex]Area = 25 * (10 + w)[/tex] -------- A1

Next, calculate the area of the parking lots

The dimension of parking lot A is: 13.5 by 10

The dimension of parking lot B is: 13.5 by w

The dimension of parking lots A and B (as an entity) is: 13.5 by 10 + w

The area is then calculated as:

[tex]Area = 13.5 * (10 + w)[/tex] -------- A2

The area of the shopping center is then calculated as:

[tex]Area = A_1 + A_2[/tex]

[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Reflect triangle ABC over the x-axis. Then translate the new triangle 5
units to the left. What are the coordinates of the vertices of the final image?

Answers

Answer:

The coordinates of the vertices of the final image will be:

A''(-6, 8), B''(-7, -2), and C''(0, -2)

Hence, option (B) is true.

Step-by-step explanation:

Given the triangle with the vertices

A(-1, -8)B(-2, 2)C(5, 2)

We know that when we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate reverses its sign.

Thus,

The rule of reflection across the x-axis:

(x, y) → (x, -y)

A(-1, -8) → A'(-1, -(-8)) = A'(-1, 8)

B(-2, 2) → B'(-2, -2) = B'(-2, -2)

C(5, 2) → C'(5, -2) = C'(5, -2)

Then, translate the new triangle 5 units to the left

Rule of translating 5 units to the left

(x, y) → (x-5, y)

A'(-1, 8) → A''(-1-5, 8) = A''(-6, 8)

B'(-2, -2) → B''(-2-5, -2) = B''(-7, -2)

C'(5, -2) → C''(5-5, -2) = C''(0, -2)

Therefore, the coordinates of the vertices of the final image will be:

A''(-6, 8), B''(-7, -2), and C''(0, -2)

Hence, option (B) is true.
