No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.

Graph C is the correct option.

If you drew a straight line (mostly) connecting the points, it would be linear. A relationship is linear if one variable, in this case, x, increases by approximately the same rate as the other variables, in this case y.

If you drew lines connecting points on the other graphs, they wouldn’t resemble a straight line, therefore, they aren’t linear.

Answer: The answer to your question is 6 $\sqrt{3}$

Step-by-step explanation:

To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.

Medium triangle Large triangle

hypotenuse y 9 + 3

adjacent size 9 y

- Write the proportions

y/9 = (9 + 3)/y

-Solve for y

y² = 9(12)

y² = 108

y = $\sqrt{180}$

-Find the prime factors of 108

108 2

54 2

27 3

9 3

3 3

then, 108 = 2² 3³

-Expressthe root as fractional exponents

2²/² 3²/² 3¹/²

-Simplification

2(3)(3)¹/²

-Result

6 $\sqrt{3}$

£140 is divided between Angad, Nick & June so that Angad gets twice as much as Nick, and Nick gets three times as much as Ju

kramer

Answer:

Step-by-step explanation:

Let's say Nick gets amount N, Angad amount A, and June amount J.

Here's what we know:

A+N+J=140

A=2*N

N=3*J.

Let's plug these values in.

N=3*J, so A+N+J=140 can now be A+3*J+J=140.

A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!
