Pls Help. Evaluate the following expression

Answers

Answer 1

Step-by-step explanation:

[tex]9 + \frac{ {8}^{3} }{2} \\ 9 + \frac{8 \times 8 \times 8}{2} \\ 9 + \frac{512}{2} \\ 9 + 256 \\ 265[/tex]

Answer 2

It’s really simple you can just type the equation into the calculator but it’s basically 8^3 which is 8 x 8 x 8 which is 512 and divide that by 2 which is 256 and add 9 which is 265.

1. when r = 0,
the expression becomes (5(0)+ 1/5)^2
= (0+1/5)^2
= 1/5^2
=1/25

2. divide the number of people by 80
saturday: 1210/80
= 15.125
= 15 as you can’t have 0.125 gift cards

What is the scale factor of the dilation?

Is the dilation an enlargement or a reduction?

Answers

Answers:

Scale Factor = 3/4

This is a reduction

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

Explanation:

Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).

Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '

we have x = 4 jump to 4k which is the x coordinate of point R'

So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75

We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.

Answer:

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)

Answer:

Step-by-step explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 + 576 = 900²

c² =810000

c= [tex]\sqrt810000[/tex] = 900

c=900ft

Frodo ran 2 3/5 miles in 7/12 of an hour. How many miles can Frodo run in one full hour?

Answers

To find how many miles he ran, we need to convert 7/12 of an hour to a full hour. To get a full hour, we must multiply 7/12 by 12/7. Knowing this, we need to multiply 2 3/5 miles by 12/7.

2 3/5 * 12/7

This would be

156/35 miles or 4 16/35 miles
