a) 5/7
b) 4459 cm cube
c) 2275 cm cube
Step-by-step explanation:
Step 1 :
a)
The Side AB (28 cm) has been scaled to side DE (20 cm)
Let x b the scale factor.
Then we have 28 *x = 20
=> x = 20/28 = 5/7
Hence the scale factor is 5/7
Step 2 :
b)
Given the height of the triangular prism is 15 cm
Volume = ( 1/2 ) * base* height of the triangle * height of the prism
= (1/2)* 21*28*15 = 4410 cm cube.
Step 3 :
c)
Given volume of the triangular prism with base ABC is 4459 cm cube
The scale factor is 5/7
Hence the volume of the prism with DEF as base is
4459 * (5/7)*(5/7) = 2275 cm cube.
The total value would be the amount he put in plus the amount he earns in interest. The answer should be 424
Answer:
I believe that it would take 5 hours for 8 people to paint 8 fences.
Step-by-step explanation:
If 2 people are painting 2 fences in 5 hours, then 8 people can also paint 8 fences in the same time because each person is painting one fence. It take 5 hours to paint 1 fence if 1 person is painting it. The same goes for 2 or 8 people painting the same amount of fences as there are people. Im not 100% sure if this is accurate but I hope it helps.
