Answer:

g = -3

Step-by-step explanation:

-2(4g-3)=30

Divide each side by -2

-2/ -2 *(4g-3)=30/-2

4g -3 = -15

Add 3 to each side

4g -3 +3 = -15+3

4g = -12

Divide each side by 4

4g/4 = -12/4

g =-3

Grace is practicing free throws. The probability that she will shoot the ball into the basket is 5/9 . What is the probability t
Naddika [18.5K]

Answer:

There is a 25/81 probability that Grace will make both of her next two shots.

Step-by-step explanation:

The probability of her making the first shot is 5/9.

The probability of her also making the shot after that is still 5/9, that does not change.

To find the probability of both of those events, multiply the fractions.

5/9 * 5/9

25/81.

How to solve the problem and the answer plz.
BlackZzzverrR [31]

Answer:

x° =125° y°= 125°

Step-by-step explanation:

55° + x° = 180° because they are complementry angles

solve for x by subtracting 55° from both sides

x° = 125°

x° and y° is equal because they are vertical angles

If a sprinkler waters 1/15 of a lawn in 1/3 hour, how much time will it take to water the entire lawn?
sammy [17]

Answer:

ok so first we know that 1/3 of a hour is 20 minutes since

60*1/3=20

so every 20 minutes 1/15 of the lawn is mowed then we need to just multiply 20 by 15

20*15=300

300 minutes or 5 hours

Hope This Helps!!!

2 Construct a rational function that will help solve the problem. Then, use a calculator to answer the question.
vaieri [72.5K]

Answer:

<u><em>Dimension of box:-</em></u>

Side of square base = 10 in

Height of box = 5 in

Minimum Surface area, S = 300 in²

Step-by-step explanation:

An open box with a square base is to have a volume of 500 cubic inches.

Let side of the base be x and height of the box is y

Volume of box = area of base × height

                 500=x^2y

Therefore, y=\dfrac{500}{x^2}

It is open box. The surface area of box, S .

S=x^2+4xy

Put  y=\dfrac{500}{x^2}

S(x)=x^2+\dfrac{2000}{x}

This would be rational function of surface area.

For maximum/minimum to differentiate S(x)

S'(x)=2x-\dfrac{2000}{x^2}

For critical point, S'(x)=0

2x-\dfrac{2000}{x^2}=0

x^3=1000

x=10

Put x = 10 into y=\dfrac{500}{x^2}

y = 5

Double derivative of S(x)

S''(x)=2+\dfrac{4000}{x^3} at x = 10

S''(10) > 0

Therefore, Surface is minimum at x = 10 inches

Minimum Surface area, S = 300 in²
