<h2>a. Answer:</h2>

For this question we'll use the following method:

1. Let's subtract old value from new value

185$-160$ = -25$

The negative value implies that the price has decreased

2. Divide the result by the old value

25$/185$ = 0,1351

3. Convert this value to percentage:

0,1351 x 100 = 13,51%

Finally, by rounding to the nearest tenth:

13,5%

That means 13,5% decrease

<h2 /><h2>b. Answer:</h2>

1. Let's subtract old value from new value

77$-56$ = 21$

The positive value implies that the price has increased

2. Divide the result by the old value

21$/77$ = 0,2727

3. Convert this value to percentage:

0,2727 x 100 = 27,3%

Finally, by rounding to the nearest tenth:

27,3%

That means 27,3% increase

PLEASE HELP ME: the ratio of cars to trucks on a highway at any given time is 12 to 8. If there are always more than 105 cars on
andre [41]

Answer:

70

Step-by-step explanation:

First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.

Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.

3. Polygon ABCDE is congruent to polygon TVSRK. EAB corresponds to _____.
mars1129 [50]

Answer: The answer is (A) ∠T.

Step-by-step explanation:  Given that the polygon ABCDE is congruent to the polygon TVSRK. We are to find the corresponding angle of ∠EAB.

In the two polygons, the corresponding vertices are

A ⇒ T

B ⇒ V

C ⇒ S

D ⇒ R

E ⇒ K.

Therefore, ∠EAB, which is ∠A will correspond to ∠T.

Thus, the correct option is (A) ∠T.
