Collin noticed that various combinations of nickels and dimes could add up to $0.65.

• Let x equal the number of nickels.
• Let y equal the number of dimes.

What is the domain where y is a function of x and the total value is $0.65?

Answer:

m = 2500b

Step-by-step explanation:

As instructed,

let b = number of boxes sold

let m = total money made.

The total money made, is a function of the number of boxes sold.

Let me break this down:

There are 100 pencils in a box;

if they sold only one box, they will get 100 X $25 = $2500;

if they sold two boxes, they will get 200 X $25 = $5000;

if they sold three boxes, they will get 300 X $25 = $7500;

Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25

representing this using the variables we were given, we have

m = 100b X 25

hence

m = 2500b

Answer:

i think ( -15,5) and ( 25, 20) might be your answer

Answer:

The length of the altitude from the right angle to the hypotenuse of a right triangle is the geometric mean of the two segments that make the hypotenuse.

Answer:

20 can work as an improper fraction, like 20/1. or you can de-simplify it or whatever it's called and make it like 40/2 or 80/4. Hope this helps. :)

Answer:

Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

1/2 of 8 is 4

4x10= 40

40x3= 120

1/2 of 8=4

4x6.9= 27.6

120+27.6=147.6 sq. m

Andre thinks it can be represented with what?

Answer:

x = 40

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

126° is an exterior angle of the triangle, then

x + 2x + 6 = 126

3x + 6 = 126 ( subtract 6 from both sides )

3x = 120 ( divide both sides by 3 )

x = 40

Answer:

Option F, 10 inches.

Step-by-step explanation:

For a circle of radius R, the perimeter is:

P = 2*pi*R

such that pi = 3.14

If we have a section of that circle defined by an angle θ, the length of the arc is:

A = (θ/360°)*P =  (θ/360°)* 2*pi*R

In this case, we have a circle whose radius is defined by the length of the windshield wiper.

We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.

Then:

A = 2*[(90°/360°)*2*3.14*R] = 31in

We need to solve this for R.

R = 31in/( 2*(90°/360°)*2*3.14) = 9.8in

We can round this to the next whole number:

R = 10in

The correct option is F.

convince me with my question (brainliest plzz)

The midpoint of the line segment is (-1, -1).

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

It is obtained by averaging the x-coordinates and averaging the y-coordinates of the endpoints of the segment.

Given endpoints

A(− 4, −5) and B(2, 3)

Midpoint of the line segment formula:

Midpoint of a Line Segment : Its x value is halfway between the two x values · Its y value is halfway between the two y values.

Midpoint [tex]= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2})[/tex]

Midpoint = [tex](\frac{-4+2}{2} ,\frac{-5+3}{2} )[/tex]

Midpoint = [tex](\frac{-2}{2}, \frac{-2}{2} )[/tex]

Midpoint = (-1, -1)

The midpoint of the line segment is (-1, -1).

Answer:

6 units

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

A rectangle’s width is one-fourth of its length.

W = 1/4 × L

W = L/4

Cross Multiply

L = 4W

A = 9 square units

Hence

9 = L × W

We substitute 4W for L

9 = 4W × W

9 = 4W²

We square root both side

√9 = √4W²

3 = 2W

W = 3/2

W = 1 1/2 unit or 1.5 units

Solving for L = Length

9 = L × W

9 = L × 1.5

L = 9/1.5

L = 6 units

Therefore, the Length of the rectangle = 6 units

Answer:

525kg

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Let  weight = x

Then, Polar bear = 3x

Baby elephant = 1x

Total weight = 700kg

3x + 1x = 700 kg

4x = 700kg

x = 700 ÷ 4

= 175kg

By putting the value of x, we get

Polar bear weight = 3x = 3 × 175

= 525kg

Hence the weight of the polar bear is 525kg.
