A purple hot-air balloon is 90 feet off the ground and rising at a rate of 7 feet per second. A yellow hot-air balloon is 120 feet off the ground and rising at a rate of 4 feet per second. Which equation could represent this situation and determine after how many seconds, s, the purple hot-air balloon will be the same height as the yellow hot-air balloon?
1 point
90 + 7s = 120 + 4s
7s + 120 = 4s + 90
90s + 7 = 120s + 4
11s = 210

Answers

Answer 1

90+7s = 120 + 4s

11s = 210

It is well-known that in Hanover in the Spring, it is either sunny or rainy every day, and the probability that the weather one day is the same as the weather the previous day is 2/3. Suppose it was sunny on May 1st and May 10th. What is the probability that it was sunny on May 3rd

Answers

Answer:

0.44

Step-by-step explanation:

May 1st was a sunny day. May 10th was a sunny day. The date closest to May 3rd is May 1st so analysis can start from there.

The probability that the weather one day is same as the weather on the previous day = 2/3

In this light, the probability that May 2nd was a sunny day is 2/3 (since May 1st was sunny).

The probability that it was sunny on May 3rd is 2/3 of 2/3 = 2/3 × 2/3 = 4/9 = 0.44

Answers

Answer:

x = 14

Step-by-step explanation:

7x + 9 + 5x + 3 = 180

7x + 5x = 180 - 3 - 9

12x = 168

x = 168 / 12

x = 14

Answer:

Step-by-step explanation:

By applying the vertical angle theorem to 5x + 3, using same-side exterior angle theorem, we can find that:

(7x + 9) + (5x + 3) = 180

Now to find x, we can just solve for x in the equation we found.

(7x + 9) + (5x + 3) = 180

Combine like terms.

12x + 12 = 180

Subtract 12 from both sides.

12x = 168

Divide both sides by 12.

x = 14

So the value of x would be 14.
