The park district is starting a new softball league. The table shows
how many coaches will be needed, depending on how many
players sign up.
Players 20 35 50
Coaches 4 7 10
Using the proportional relationship in the table, how many
coaches will be needed for 80 players?
A8
16
21
40

Answers

Answer 1

Answer:

16

Step-by-step explanation:

Since there is always a certain amount of coaches per # of players we have to find that. If there are 20 players and 4 coaches that means 5 players per coach. if there are 35 players and 7 coaches that means again 5 players per coach. Therfore we know that 5 players per coach is constant. If we have 80 players we set up a proportion to solve. 80players / x coaches = 5 players per/ 1 coach. Cross multiply and solve. 80=5x

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?

Answers

Given:

Rita covered 1 mile in 15 minutes.

She covered 3 miles in 30 minutes.

To find:

The rate at which she is riding.

Solution:

Let y be the number of miles covered in x minutes.

Rita covered 1 mile in 15 minutes. So, the point is (15,1).

She covered 3 miles in 30 minutes. So, the point is (30,3).

Slope of the line:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-1}{30-15}[/tex]

[tex]m=\dfrac{2}{15}[/tex]

Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the reversed number. Find the number.

Answers

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

[tex]T + U = 8[/tex]

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

Required

Find the digit

Make U the subject in the first equation

[tex]U = 8 - T[/tex]

Substitute 8 - T for U in the second

[tex]10T + U - (10U + T) = 10 + 10U + T[/tex]

[tex]10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T[/tex]

[tex]10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T[/tex]

[tex]10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T[/tex]

Collect Like Terms

[tex]10T + 10T - T- T + 8 -80 = 10 + 80 - 10T+ T[/tex]

[tex]18T -72 = 90 - 9T[/tex]

[tex]9T + 18T = 90 + 72[/tex]

[tex]27T = 162[/tex]

[tex]T = 162/27[/tex]

[tex]T = 6[/tex]

Recall that:

[tex]U = 8 - T[/tex]

[tex]U = 8 - 6[/tex]

[tex]U = 2[/tex]

Hence, the number is 62

Determine the GCF of 18xy and 12xy

Answers

Answer:

If im correct im pretty sure its 6xy

The GCF of 18xy and 12xy is 6xy.

What is Greatest Common Factor?

The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor.

18 and 24 share one 2 and one 3 in common.

, so 2 x 3 = 6 is the GCF of 18 and 24.

Given:

18xy and 12xy

now, factoring the above terms

18xy = 2 × 3 × 3 × x × y

12xy= 2 × 2 × 3 × x × y

So, 18xy & 12xy = 2 x 3 xy = 6xy

hence, the GCF of 18xy and 12xy is 6xy.

Answers

Answer:

Read left to right

Do parenthesis first

-4 ( 1 + 5) ^2

-4 (6) ^2

Then exponent

6^2 = 6 x 6 = 36

-4 x 36 = -144

Then divide

-144 / 6 = -24

Then the next parenthesis

(42+5) = 47

-24 - 47 = -71

Step-by-step explanation:

Answer = -71
Step: -4(1+5)^2/6 -(42+5)

=-4(6^2)/6 -(42+5)

=( -4) (36)/6 -(42+5)

=-144/6 -(42+5)

= -24-(42+5)

= -24-47

Write the equation of the line that passes through (-3, -20) and (1,4).

Answers

Answer:

y=6x-2

Step-by-step explanation:

The equation of the line is y=mx+b

FINDING SLOPE: To find the slope of a given line use the equation [tex]\frac{y2-y1}{x2-x1}[/tex]

So x1=-3, y1=-20 and x2=1, y2=4

Plug those numbers into the equation: [tex]\frac{4-(-20)}{1-(-3)}[/tex]  and we get the slope which is 6.

FINDING Y-INTERCEPT: Then we find the y intercept by plugging in our points (you can choose) I will use (1,4) and solve.

y=6x+b

4=6(1)+b

b=-2

A sinking fund is established to discharge a debt of $20,000 in 15 years. If deposits are made at the end of each 6-month period and interest is paid at the rate of 5%, compounded semiannually, what is the amount of each deposit? (Round your answer to the nearest cent.)

Answers

Answer:

the amount of each deposit is $45,555

Step-by-step explanation:

The computation of the each deposit is shown below:

Given that

Future value be $20,000

Time period = 15 × 2 = 30

And, the rate = 5% ÷ 2 = 2.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($20,000 × 2.5) ÷ (1 + 0.025)^30 - 1

= $50,000 ÷ 1.0975675791

= $45,555

Hence, the amount of each deposit is $45,555

(a) What is the slope of the line? Show your work.
(b) Write the equation of the line in point-slope form. Show your work.
(c) Write the equation of the line in slope-intercept form. Show your work.

Answers

Answer:

Part A)

The slope is 3.

Part B)

[tex]\displaystyle y-1=3(x+3)[/tex]

Part C)

[tex]\displaystyle y=3x+10[/tex]

Step-by-step explanation:

We know that the line goes through the points (-3, 1) and (-2, 4).

Part A)

To find the slope of a line given two points, we can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (-3, 1) be (x₁, y₁) and let (-2, 4) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{4-1}{-2-(-3)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{3}{-2+3}=\frac{3}{1}=3[/tex]

Hence, the slope of our line is 3.

Part B)

Point-slope form is given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is our slope and (x₁, y₁) is a point.

So, let’s substitute 3 for m.

For our point, we can use either of the two given. Let’s use (-3, 1) for consistency. So, let (-3, 1) be (x₁, y₁). Therefore:

[tex]\displaystyle y-1=3(x-(-3))[/tex]

Simplify. Hence, our point-slope form is:

[tex]\displaystyle y-1=3(x+3)[/tex]

Part C)

To rewrite into slope-intercept form, we can just solve for y from our point-slope form. So, we have:

[tex]\displaystyle y-1=3(x+3)[/tex]

Distribute on the right:

[tex]\displaystyle y-1=3x+9[/tex]

Add 1 to boths sides. So, our slope-intercept equation is:

[tex]\displaystyle y=3x+10[/tex]
