(4, 1), (8, 2), (12, 3)
(2, 1), (4, 3), (5, 4)

Answers

Answer:

The answer is B and C.  

Step-by-step explanation:

The pairs (2, 2), (4, 4), and (6, 6) have ratios of 1 and the pairs (4, 1), (4, 1),  (8, 2), and (12, 3) have ratios of 4. The other pairs do not have similar ratios.

Answer:

(2, 2), (4, 4), (6, 6)

(4, 1), (8, 2), (12, 3)

Step-by-step explanation:

These are the only two where the ratios are the same for each ordered pair

If you plot them you will get a straight line with non-zero slope

The others do not show this characteristic

First one has ratios
2/1, 3/2 and 7/4 not same

Third one has ratios

1/3, 1/4, 1/5

Last one has ratios

1/2, 3/4 and 4/5

You have 4 pounds of clay. You are going to use 2/5 of how it to make a bowl. How many pounds of clay are you going to use to make the bowl?

A. 3 1/2

B. 4 pounds

C. 2 1/2

D. 1 3/5

Answers

Answer:     D. 1 3/5

Step-by-step explanation

2/5=0.4

4x0.4=1.6

1.6=1 3/5

2/5 is equal to 40% (5x20= 100 and 2x20= 40) and 40% of 4 (4x0.4) is 1.6 which could also be 1 3/5 because 5x2 is 10 and 3x2 is 6 so the answer would be D

Drag and drop one set of parentheses into the expression below so that it's value when simplified is 31. Where would these ( ) go? _2_*4^2_+_square root36_-_13_

Answers

Answer:

2 * (4^2 + squared root of 36) - 13

since the space where the _ are, that's where the parenthyeses would be placed. If you place these around 2, you get 25, is around 4^2, it's also 25, if placed around square root of 36, it will also be 25, but if placed around -13, it's -46. But place then around 4^2 + the square root of 36, then you will get your answer of 31 simplified.

The answer is 2* (4^2 + squared root of 36) - 13

Fabiola’s basketball team practices 4.25 hours each week basketball season is 14 weeks long .how much time does Fabiola’s spend in practice during the season? and show how to do the problem

Answers

Answer:

59.5 hours

Step-by-step explanation:

Since Fabiola has basketball practice for 4.25 hours each week and we need to find how much she practices for 14 weeks, you have to multiply.

4.25 x 14 = 59.5

In order to determine the total time, we simply need to multiply 4.25 hours by 14, since the length of time is dependent to the number of weeks.

= (14)(4.25)

=59.5

Final answer:
Fabiola's team spend 59.5 hours in 14 weeks.
