6 0

Answer:

V=(3W^3+12W^2)\ units^3

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

V=LWH -----> equation A

where

L is the length

W is the width

H is the height

we know that

L=3W -----> equation B

H=W+4 ----> equation C

substitute equation B and equation C in equation A

V=(3W)(W)(W+4)

Apply distributive property

V=(3W^3+12W^2)\ units^3

For PE Mr Jones wants to split boys and girls equally into as many mixed groups as possible. There are 168 boys and 60 girls. Ho
Bond [772]

Answer:

12

Step-by-step explanation:

You need the greatest common factor of 168 and 60.

168 = 2^3 * 3 * 7

60 = 2^2 * 3 * 5

For the GCF, you need common factors with the lower exponent.

Between 2^3 and 2^2, choose 2^2.

Then you have 3 as a common factor.

5 and seven are not common.

GCF = 2^2 * 3 = 12

Find the value of x to the nearest tenth.
Lana71 [14]

Answer:

x = 14.7

Step-by-step explanation:

Use Law of Sines.

7/sin20=x/sin46

cross multiply

7sin46=xsin20

divide both sides by sin20 to isolate x

x = 7sin46/sin20

x = 14.72

Divide £2400 into the ratio 5:7
sergiy2304 [10]

Answer:

£1000, £1400

Step-by-step explanation:

Sum the parts of the ratio 5 + 7 = 12 parts

Divide the amount by 12 to find the value of one part of the ratio.

£2400 ÷ 12 = £200, thus

5 parts = 5 × £200 = £1000

7 parts = 7 × £200 = £1400
