Answer:

Step-by-step explanation:

Simplify the following:

8 (6 + 5)/2^2 + 6×2

8 (6 + 5)/2^2 = (8 (6 + 5))/2^2:

(8 (6 + 5))/2^2 + 6×2

2^2 = 4:

(8 (6 + 5))/4 + 6×2

6 + 5 = 11:

(8×11)/4 + 6×2

8/4 = (4×2)/4 = 2:

2×11 + 6×2

2×11 = 22:

22 + 6×2

6×2 = 12:

22 + 12

| 2 | 2

+ | 1 | 2

Show work Find the volume of the pyramid

Burka [1]

Hello there, and thank you for posting your question here on brainly.

______________________________________________________________
Answer: 128
Why?
______________________________________________________________
To find the volume of a cylinder, we have to use the formula lwh/3. The length is 8, width is 4, and height is 12. So we have to multiply all of those together, then divide by 3. (8 * 4 = 32) -> (32 * 12 = 384) -> (384/3 = 128) The volume is 128.

Hope this helped you! ♥

Mallory is training for a marathon. She ran for 15 minutes on the 1* day, 19

lilavasa [31]

the amount of time that she runs on the n-th day is:

T = 4min*n + 11min

And on day number 30 is:

T = 4min*30 + 11min = 133min

We know that:

She ran for:

15 minutes on the 1* day
19 minutes on the 2nd day
23 minutes on the 3rd day
27 minutes on the 4th day.

So on each consecutive day that she runs, she adds 4 minutes to the running time. This is a linear relationship.

So, if we define n as the day number, we can write the time T of running as:

T = 4min*n + b

Where b is a constant, notice that when n = 1 (the first day) the time of running is 15 minutes, then:

15 min = 4min*1 + b

15 min - 4min = 11 min =b

Then the amount of time that she runs on the n-th day is:

T = 4min*n + 11min

And on day number 30 is:

T = 4min*30 + 11min = 133min

I’m going to need a serious answer through this one or I’m screwed.

Elina [12.6K]

Answer:

A = 60 ft²

Step-by-step explanation:

the area (A) of the shaded sector is calculated as

A = area of circle × fraction of circle

= 90 × $\frac{240}{360}$

= 90 × $\frac{2}{3}$

= 30 × 2

= 60 ft²
