Megan's age is three years more than four times her daughter's age. If Megan's daughter's age is $d$ , Megan's age is

Answers

Answer: 4d + 3

Step-by-step explanation:

Megan's daughter's age = d

Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:

= (4 × d) + 3

= 4d + 3

Therefore, Megan's age is 4d + 3.

For example, if the daughters age is 7 years, Megan's age will be:

= 4d + 3

= 4(7) + 3

= 28 + 3

= 31 years

there are two holes in the roof that are leaking water. the one in the bathroom drift 120 drops in an hour. the other one in the kitchen dripped 80 drops in 30 minutes. which one is leaking more water?

Answers

Answer:

the more leaking place is the bathroom

Explanation:

1 hour=60 minutes

the bathroom drift 120 drops in 60 minutes

so, the bathroom drift 1 drop in 120/60 minutes

=60 minutes

the other one in the kitchen dripped 80 drops in 30 minutes.

so, the other one in the kitchen dripped 1 drop in 80/30 minutes

= 8/3 minutes

so the more leaking place is the bathroom because 60 > 8/3

The ratio of boys to girls in the 10th grade is 8 to 13. If there are 91 girls in 10th grade, then how many boys are there?

Answers

Answer: There are 56 boys in the 10th grade

Step-by-step explanation:

Step 1

ratio of boys to girls in the 10th grade is 8 :13

Number of girls= 91

To find the number of boys, we first find the total number of boys and girls in the 10th grade

Step 2

Now the total ratio= 8 +13=21

Number of girls = ratio of girls/ total ratio x Total number of students

91=13/ 21 x Total number of students

Total number of students =21 x 91 / 13 =147

Step 3

Therefore Number of boys =ratio of boys/ total ratio x Total number of student

8/21 x 147=56

solve 6x + 6 = 3x - 6

Answers

Answer:

x = -4

I hope it's helps you t

Answer:

x = -4

Step-by-step explanation:

Simplifying

6x + 6 = 3x + -6

Reorder the terms:

6 + 6x = 3x + -6

Reorder the terms:

6 + 6x = -6 + 3x

Solving

6 + 6x = -6 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

6 + 6x + -3x = -6 + 3x + -3x

Combine like terms: 6x + -3x = 3x

6 + 3x = -6 + 3x + -3x

Combine like terms: 3x + -3x = 0

6 + 3x = -6 + 0

6 + 3x = -6

Add '-6' to each side of the equation.

6 + -6 + 3x = -6 + -6

Combine like terms: 6 + -6 = 0

0 + 3x = -6 + -6

3x = -6 + -6

Combine like terms: -6 + -6 = -12

3x = -12

Divide each side by '3'.

x = -4

Select the correct function. Select the function with an average rate of change of 3 over the interval [1, 3].

Answers

Answer:

Function g(x)

Step-by-step explanation:

Given

See attachment for functions

Required

Which has an average rate of 3 over [1,3]

The average rate of change (m) is calculated as:

[tex]m = \frac{f(b) - f(a)}{b -a}[/tex]

Where:

[tex][a,b] = [1,3][/tex]

So, we have:

[tex]m = \frac{f(3) - f(1)}{3 -1}[/tex]

[tex]m = \frac{f(3) - f(1)}{2}[/tex]

From the table f(x), we have:

[tex]f(3) = 6\\ f(1) = -2[/tex]

So:

[tex]m = \frac{6 - -2}{2}[/tex]

[tex]m = \frac{8}{2}[/tex]

[tex]m =4[/tex]

From the graph of g(x), we have:

[tex]g(3) = 4\\ g(1) = -2[/tex]

So:

[tex]m = \frac{g(3) - g(1)}{2}[/tex]

[tex]m = \frac{4 - -2}{2}[/tex]

[tex]m = \frac{6}{2}[/tex]

[tex]m =3[/tex]

Since only one of the function has an average rate of change of 3 over the given interval,

Then g(x) answers the question

WILL REWARD BRAINIEST! What is the volume of the composite figure if both the height and the diameter of the cylinder are 10.5 feet? Give the exact answer and approximate to two decimal places.

Answers

Answer:

908.74

Step-by-step explanation:

The formula for the volume of a cylinder is V = h * pi * r^2

h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.

So now plug it into the formula:

V = 10.5 * pi * (5.25)^2

= 908.74

Hope this helped! :)

Answer:

1211.65 cubed ft.

Step-by-step explanation:

Half sphere: V = 4/3(3.24)(5.25^3)

V = 605.82

Divide by two since we need to find the volume of the half sphere, not the full sphere.

605.82 ÷ 2 = 302.91

Cylinder: V = (3.14)(5.25^2)(10.5)

V = 908.74

Add the two volumes to each other to find the total volume of the composite figure.

908.74 + 302.91 = 1211.65
