A museum has a wax sculpture of a historical village. The scale is 1.5:8. If the height of a hut in the sculpture is 5 feet, how
Oksi-84 [34.3K]

Let us say that x is the real height of the original hut, therefore we can establish the equation:

5 : x = 1.5 : 8

5 / x = 1.5 / 8

 

Solving for x:

x = 5 * 8 / 1.5

x = 40 / 1.5

<span>x = 26.67 ft</span>

I need help in this please! thank you so much!

Answer:

C) p(x) has a zero between x=2 and x=4

Step-by-step explanation:

For a polynomial p(x), p(a)=R means that, when p(x) is divided by x-a, the remainder is R.

This is called the remainder theorem

Therefore p(2)=1, p(4)=-1 means that when p(x) is divided x-2 and x-4 is 1 and -1 respectively.

Also the Intermediate value theorem says that, if p(a) and p(b) have opposite signs then there is a certain c on (a,b) where f(c)=0 i.e there is a zero between a and b

Therefore the correct answer is C

Please help me answer these 2 questions, worth lots of points
alexgriva [62]
For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.
