Answers:

1. V=triangle area × length

V=1/2×8×12×20

V=960in³

2. triangle area × length

Area of the triangle=1/2×4×11

A=22ft²

V=22×6

V=132ft³

3. b, volume always have cubic power (³)

4. d, same reason of question 3

(GIVING BRAINLIEST AND EXTRA POINTS!!!)

rosijanka [135]

Answer:0.65

Step-by-step explanation:

Firstly, we convert the fractions into decimals:

6/10=0.6

1/5=0.2

1/4=0.25

We then get : 0.6 - 0.2 + 0.25

0.6-0.2=0.4

0.4+0.25=0.65

find the value of n in each equation. write what n represents in the related division problem 643=4×160+n

schepotkina [342]

Answer: n = 3; n represents a remainder in a division problem.

Explanation:

1) Finding n:

i) Given: 643 = 4 × 160 + n

ii) Do the operations: 643 = 640 + n

iii) Subraction property of the equality: 643 - 640 = n

iv) Do the operations: 3 = n

Answer: n 3

2) Meaning of n

When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.

This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).

The type of polynomial that would best model the data is a cubic polynomial. (Correct choice: D)

<h3>What kind of polynomial does fit best to a set of points?</h3>

In this question we must find a kind of polynomial whose form offers the best approximation to the point set, that is, the least polynomial whose mean square error is reasonable.

In a graphing tool we notice that the least polynomial must be a cubic polynomial, as there is no enough symmetry between (10, 9.37) and (14, 8.79), and the points (6, 3.88), (8, 6.48) and (10, 9.37) exhibits a pseudo-linear behavior.
