A boy can swim 75 feet in 12 seconds. What is his rate to the nearest mile per hour?

Answers

Answer 1

Answer: S=d/t so in this case it's 75/12 which is 6.25. Round it and you got 6 miles per hour.

Answer 2

Answer:

Answer:

6.25

Step-by-step explanation:

75/12 = 6.25

Answer:

C = 37.68 yards.

Step-by-step explanation:

To find the circumference of a circle, you can use the formula C=2πr, where C is the circumference, π is a constant that is approximately equal to 3.14, and r is the radius. Plugging in the given value of r=6 yards, we get:

C=2×3.14×6

C=37.68

Rounding to the nearest hundredth, the circumference is 37.68 yards.

Solve this inequality: 3p – 16 < 20. A. p < 1/3
B. p < 11/3
C. p < 12
D. p < –12

Answers

If you would like to solve the inequality 3 * p - 16 < 20, you can calculate this using the following steps:

3 * p - 16 < 20
3 * p < 20 + 16
3 * p < 36 /3
p < 36/3
p < 12

The correct result would be C. p < 12.

The solution to the inequality is p < 12.

Option C is the correct answer.

We have,

To solve the inequality 3p - 16 < 20, you can follow these steps:

- Add 16 to both sides of the inequality:

3p - 16 + 16 < 20 + 16

3p < 36

- Divide both sides of the inequality by 3

(since the coefficient of p is 3 and we want to isolate p):

(3p)/3 < 36/3

p < 12

Thus,

The solution to the inequality is p < 12.

Solve 4/(x + 1) - 1/x = 1 over the real numbers.

Answers

$( 4)/(x + 1) - (1)/(x) = 1 \n \nx+1\neq 0 \ \ \ and \ \ \ x\neq 0 \n \nx\neq -1 \ \ \ and \ \ \ x\neq 0 \n \nD=R\setminus \left \{ -1,0 \right \}$

$( 4x- (x+1))/(x(x + 1)) = 1 \n \n( 4x- x-1 )/(x^2+ x)=1 \n \n( 3x -1 )/(x^2 + x) = 1 \n \n3x-1=x^2+x\n \n x^2+x-3x+1=0$

$x^2-2x+1=0 \n \n (x-1)^2=0 \n \nx-1=0 \n \nx=1$

Ok sorry I guessed this one but it was x = 1
4/(1+1) - 1/1 = 1
2 - 1 = 1
And it's right :)
