Volume= L * W * H
The measurements need to be the same units before multiplying.
V = 56.5* 17* (13/12) = 1040.54 ft^3
It may need to be rounded to the nearest whole number per the instructions.
1041 ft^3

A side of the triangle below has been extended to form an exterior angle of 128°. Find the value of x.

hjlf

First you take the 128 and subtract it from 180. You then take the angle that’s vertical from it and place the number (52) and you add 52 + 24 to get 76. After that you take 76 and subtract it from 180 to get 104. X=104

Please answer this correctly without making mistakes

Nadya [2.5K]

Answer:

17/16 OR $1\frac{1}{16}$ minutes

Step-by-step explanation:

Since Jayla spent 1/16 of a minute AND one whole minute watching a millipede crawl, we'd need to first add the two numbers.

Since the given minute is out of 16, we can convert the one minute to 16/16. This means we can add the other 1/16 of a minute.

This leaves us with Jayla watching the millipede for 17/16 OR $1\frac{1}{16}$ minutes.

Hope this helps!! <3 :)

During the summer holidays sarah earns pocket money by mowing lawn. She can mow 6 lawns in 1 1/2 and clean the pool in one-sixth

tigry1 [53]

Answer:

It will take Sarah 2 1/2 hours to mow 10 lawns

It will take Sarah 1 2/3 hours to clean 10 pools

Step-by-step explanation:

During the summer holidays, Sarah earns pocket money by mowing the lawn. She can mow 6 lawns in 1 1/2 hour and clean a pool in one-sixth of an hour. How long does Sarah take to clean 10 pools and 10 lawns?

Number of lawns : Time to mow lawns = 6 : 1 1/2

= 6 : 3/2

Number of lawns : Time to mow lawns = 10 : x

6 : 3/2 = 10 : x

6 ÷ 3/2 = 10/x

6 * 2/3 = 10/x

12/3 = 10/x

Cross product

12 * x = 3 * 10

12x = 30

x = 30/12

x = 2 6/12

x = 2 1/2 hours

It will take Sarah 2 1/2 hours to mow 10 lawns

Number of pools cleaned : time taken = 1 : 1/6

Number of pools cleaned : time taken = 10 : x

1 : 1/6 = 10 : x

1 ÷ 1/6 = 10/x

1 * 6/1 = 10/x

6 = 10/x

Cross product

6 * x = 10

6x = 10

x = 10/6

x = 1 4/6

x = 1 2/3 hours

It will take Sarah 1 2/3 hours to clean 10 pools

Select all of the answers that are elements of M = {x | x is a month of the year}

BlackZzzverrR [31]

Answer:

{January, February, March, April, May, June, July, August, September, October, November}

Step-by-step explanation:

The set is formed by months of year with indexes larger than 0 and lesser than 12.

The year starts at month 1, which is January, and finishes at month 12, which is December.

Since we want lesser than 12, December is not part of the set. So the answer is given by:

{January, February, March, April, May, June, July, August, September, October, November}
