Answer 1

The number of ways is an illustration of combination

There are 1012 ways to send at least 2 and no more than 9 pledges to work

How to determine the number of ways

The given parameters are:

Pledges = 10

To send between 2 and 9 pledges

Start by calculating the number of ways to send all the pledges

[tex]n = 2^{10}[/tex]

Also,

0th pledge can be sent in 1 way1st pledge can be sent in 1 way10th pledges can be selected from any of the 10 pledges

The number of ways the pledges can be sent is then calculated using the following complement rule

[tex]Ways = 2^{10} -1-1-10[/tex]

Evaluate the expression

[tex]Ways = 1012[/tex]

Hence, there are 1012 ways to send at least 2 and no more than 9 pledges to work

You lose track of how many 2-point baskets and 3-point baskets a team makes in a basketball game. The team misses all the 1-point baskets and still scores 54 points. The equation 2x+3y=54$ models the total points scored, where x is the number of 2-point baskets made and y is the number of 3-point baskets made. a. Find and interpret the intercepts.

Answers

Answer:

x-intercept: 27, the number of 2-pointers if no 3-pointersy-intercept: 18, the number of 3-pointers if no 2-pointers

Step-by-step explanation:

Each intercept is found by setting the other variable to zero and solving for the variable value of interest.

  2x +3y = 54

x-intercept:

  2x = 54

  x = 27

y-intercept:

  3y = 54

  y = 18

__

By definition, the intercept values are the values that satisfy the equation when the other variable is zero.

x-intercept: To score 54 points, the team would have to make 27 2-point baskets if no 3-point baskets were made.

y-intercept: To score 54 points, the team would have to make 18 3-point baskets if no 2-point baskets were made.

If 2 pints = 1 quart, how many pints are in a 26-quart container

Answers

There are 52 pints in 26 quarts containers

Answer:

52 pints

Step-by-step explanation:

Given;

2 pints = 1 quart

To Find;

How many pints are in a 26-quart container

Solve;

Since 2 pints = 1 quart

Then the Formula = divide the volume value by 2

The equation for 2 pints = 1 quart is 2 ÷ x = 1

which x = 2.

Thus, the equation for 26 quart container = how many pints =

x ÷ 2 = 26

Divide/Multiply sides by 2

2x/2 = 26 * 2

Simplify

x = 52

Hence, there are 52 pints in a 26 quart container

[] The equation on the left, 292 [tex]\frac{1}{2}[/tex]  = 18 * 6 [tex]\frac{1}{2}[/tex]  * h

-> Volume is length times width times height. When we plug in all the values we have to solve for h (height) we get this equation.

[] The height is 2.5 inches

-> We will solve the equation above.

-> Multiply 18 by 6 and a half = 117

-> Divide 292 and a half by 117 = 2.5

-> The height is 2.5 inches or 2 [tex]\frac{1}{2}[/tex]inches

292 [tex]\frac{1}{2}[/tex] = 18 * 6 [tex]\frac{1}{2}[/tex]  * h
