A bit of advice for you guys, if theres an answer on this cite and they match the answers on your test 9 time outta 10 its correct
Answered by Les
Can someone give an explanation for question 6? I don't want answers, i want help on how to solve it.
Answered by Kittycat
Sure, I can help @Les. So, number 6 asks you to find the surface area of another similar pyramid. What you want to do, is take the smaller pyramids surface area and put it over the larger ones. We know that it is 90 in^2, however we do not know the larger vases surface area, therefore we should use x. 90/x. The height of the pyramids are 5 and 10. We have to make those into a fraction to create a proportion. This is 5/10. but since we are finding surface area, we have to square it. So 5x5=25, 10x10=100. Our fraction will be 25/100. Now we set up the proportion. 90/x=25/100. Use cross products to get 90x100= 25 x x. 90x100= 9000. Then we have to isolate the variable. We divide both sides by 25 to isolate it. 9000/5=360. x=360. Remember to add the square root sign since it is surface area. 360 in^2.
Answer
Sorry, I realise I put vases. I meant the pyramids.
The math is still correct though.
