Part B
How many pounds of cucumbers did Josh actually buy? Show your work.

Answers

Answer 1
Answer: Please refer to the other post you saw.

Josh's estimate IS reasonable because when you have a number 5 or above after the decimal, you round up. Although it's reasonable to round up to 5 pounds, the actual amount is 4.5 pounds, or four and a half.

Is 7/20 equivalent to 7 hundreds

Answers

No. 7/20 is NOT equivalent to 7 hundreds or 7 hundredths.

7 hundreds is 700 in standard form.

7/20 will become a decimal number. It is equal to 0.35

0.35 is not equal to 700.

7 hundredths in decimal form is 0.07

0.35 is still not equal to 0.07.

If a sequence is defined recursively by f(0) = 2 andf(n +1) = -2f(n) + 3 for n ≥ 0, then f(2) is equal to

Answers

If you would like to know how much is f(2), you can calculate this using the following steps:

f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5

The correct result would be f(2) = 5.

How do i find the answer to this question?

Answers

Answer is choice D) AC < FH

Think of a door. Imagine tying a string to the handle of the door and to the metal part where the door would touch if the door was closed. The more open the door is, the longer the string would be (if the string is completely taut and there's no slack). This is the hinge theorem in action. The larger the angle, the larger the opposite side. 

Applied to this problem, we have angle G larger than angle B, so the respective opposite sides are larger in this order (FH is larger than AC). This theorem only works if we know the other two sides are fixed in length and are equal. If either AB = GH or BC = FG was false, then the hinge theorem would not work here.
the answer is D) AC<FH
