A pool 8ft wide and 25ft long was being filled with water.At 10:00 a.M the depth of the water was 2ft, at 3:00 p.M it was 5ft, h
spin [16.1K]

Answer:

  2 ft   or   16.4 ft

Step-by-step explanation:

The problem statement tells you the pool is 2 ft deep at 10:00 am.

__

The depth changes 3 ft in the 5 hours between 10 am and 3 pm, so is changing at the rate of 3/5 ft/hour. In 24 hours, it will change (3/5)(24) = 14.4 ft. Added to the 2 feet of depth at 10 am, the depth at the next instance of 10 am will be 16.4 ft.

A group of students takes a test and the average score is 72. One more student takes the test and receives a score of 88 increas
Stells [14]

Answer:

3 student.

Step-by-step explanation:

From the first statement:

Let the total score be T

Let the total number of student be x

The average of the score = 72

Average = Tota score / number of student

72 = T/x

Cross multiply

T = 72x ..... (1)

Second statement:

One more student took the test and the average becomes 76 with the student having a score of 88.

Therefore,

Overall score = T + 88

Total student = x + 1

Average = 76

Average = overall score / total number of student

76 = (T + 88) /(x + 1)

Cross multiply

76(x + 1) = T + 88

Clear bracket

76x + 76 = T + 88

From equation 1

T = 72x

76x + 76 = 72x + 88

Collect like terms

76x – 72x = 88 – 76

4x = 12

Divide both side by the coefficient of x i.e 4

x = 12/4

x = 3

Therefore, the initial number of the student were 3.

-3(t+5)+(4t+2)=8
Tanya [424]
First use distributive property on -3(t+5), which would be -3t minus -15.

Then, add all like terms: -3t-15+4t+2 ---> -3t+4t+2-15 --> t-13.

t-13=8, add 13 to both sides. This cancels the -13 and makes 8 to 21.

Therefore, t=21

Solve: 3(2x+7) S 6(x-4)
Alenkasestr [34]

Answer:

no solution

Step-by-step explanation:

3(2x + 7) ≤ 6(x - 4) ← divide both sides by 3

2x + 7 ≤ 2(x - 4)

2x + 7 ≤ 2x - 8 ( subtract 2x from both sides )

7 ≤ - 8 ← False statement

This means the inequality has no solution
