Answer:

( 212 - 0 )/ ( 100 - 32 ) = 212 / 68 = 3.11 ;

Step-by-step explanation:

Let m = slope

m = (delta y)/(delta x)

m = (212 - 32)/(0 - 100)

m = 180/(-100)

m = -180/100

You can reduce -180/100 to the lowest term. I'll let you do that.

Answer:

22.34 km²

Step-by-step explanation:

Here we have a circle whose diameter is 5  1/3 km.  As an improper fraction, that's 16/3 km.  Half that, or 8/3 km, is the radius.

The area of a circle is A = πr², where r is the radius.

In this case, the area is A = π(8/3 km)², or (64/9)π km², or 22.34 km² (same as first answer choice).

Answer:

edg 2021 answer is A

Step-by-step explanation:

To find the perimeter of a rectangle you can multiply the length by 2 and the width by 2, or you can add the four sides together.

The wrong equation is w + 3w = 90 because it only has one width and one length, which would be half the total perimeter.

Final answer:

The equation that does not correctly represent the width w of Sanjay's rectangular garden given the total fence length and length-width relationship is w + 3w = 90, as it simplifies to 4w = 90, which is not the correct equation for this context.

Explanation:

The question asks to identify which equation does not correctly represent the width w of Sanjay's rectangular garden, given that the total length of the fence is 90 meters and that the length l of the garden is three times its width w. We know the perimeter P of a rectangle is given by P = 2l + 2w, where l is the length and w is the width.

We can substitute l = 3w into the perimeter formula to get P = 2(3w) + 2w, which simplifies to P = 6w + 2w or P = 8w. Given that P = 90, the correct equation is 8w = 90. Now, let's examine the provided equations:

w + 3w = 90 simplifies to 4w = 90.

w + 3w + w + 3w = 90 simplifies to 8w = 90, which is the correct equation.

2 · w + 2 · 3w = 90 simplifies to 2w + 6w = 90 which simplifies to 8w = 90, which is also correct.

2 · (3w + w) = 90 simplifies to 2 · 4w = 90 which simplifies to 8w = 90, which is again correct.

Thus, the equation that does not give the correct value for w is w + 3w = 90.

How to draw it:

1. Draw a hollow point on number "5"

2. Draw a small vertical line on the top of the point.

3. Draw a long honrizontal line from that vertical line to the left to the end, and add an arrow.

First divide 2 to both sides to isolate b. Since 2 is being multiplied by b, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

2b ÷ 2 < 10 ÷ 2

1b < 5

b < 5

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

b < 5

aka b is less then five

This means that the graph will have an empty circle and the arrow will go to the left of 5.

Step-by-step explanation:

There is a standard cost just for renting the car.

Let the daily cost = x

Let the addon be = z The add on is the amount they charge just to give you the keys and do the paper work. It might include insurance.

y = z + 4x

y = 180

z = ??

x = 4

y = 325

z = ??

x = 9

Equation 1: 180 = z + 4x

Equation 2:325 = z + 9x

Subtract (1) from (2)

325 = z + 9x

180 = z + 4x                         Subract

145 = 5x                               Divide by 5

145/5 = 5x/5

x = 29

What you have found is the daily cost. Now you have to find the fixed cost.

y = 29x + z

180 = 29*4 + z

180 = 116 + z                  Subtract 116 from both sides

180 - 116 = z

z = 64

2.8x = 2.7x - 6                           Subtract 2.7x from both sides

2.8x-2.7x = - 6

0.1x = - 6                                    Divide by 0.1

Answer:

Rebecca has 18 nickels and 27 dimes

Step-by-step explanation:

Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.

The total value of Rebecca's coins is $3.60.

1 nickel - 5 cents

x nickels - 5x cents

1 dime - 10 cents

45-x dimes - 10(45-x) cents

Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,

5x+10(45-x)=360

5x+450-10x=360

5x-10x=360-450

-5x=-90

5x=90

x=18

45-x=45-18=27

Answer: $22.50

Step-by-step explanation: let x represent the amount Laura and Lilly contributed each. If Laura and Lilly contributed the same amount, x+x=2x=45. If 2x=45, divide both sides by 2 to find the value of x. 45/2= 22.5.

Laura contributed $15 toward the purchase of the video game.

The question is asking to determine the amount contributed by Laura to buy a video game for their brother, Liam, if the entire cost of the game is $45 and Laura contributed half as much as Lilly. For simplicity, let's assume Lilly contributed x dollars. Then Laura, contributing half as much, would have contributed x/2 dollars. Given that their total contribution is $45, we set up the equation x + x/2 = 45. Solving for x, we find that Lilly contributed $30 and Laura, half of this, contributed $15.

Step-by-step explanation:

You know that the height of the smaller cylinder is 1 cm and the height of the  larger cylinder is 3 cm, then you can find the volume ratio. This  is:

[tex]Volume\ ratio=(\frac{1\ cm}{3\ cm})^3\\\\Volume\ ratio=\frac{1}{27}[/tex]

Knowing that the volume of the larger cylinder is 2,106 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{27}(2,106\ cm^3)\\\\V_{smaller}=78\ cm^3[/tex]

We have that, the smaller cylinder has height 1 cm and the larger cylinder has height 3cm.

That's if the smaller cylinder is the image.

The volume of the larger cylinder is 2106 cm³.

Answer:

(b) 240

Step-by-step explanation:

First, we use the Pythagorean formula using the given side lengths to find x. Then we use x to find the side lengths. Then we add the side lengths to find the perimeter.

Pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

We see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. The only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

Replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

7 7/12

Step-by-step explanation:

Find the amount of rolls in all that were donated:

60 x 12 = 720.

The total amount used is 679. Subtract 679 from 720:

720 - 629 = 91.

Find the amount per dozen. Divide 91 with 12:

91/12 = 7 7/12

7 7/12 is your answer.

~

The local Youth Baseball League used 56 dozen rolls with 7 extra rolls for a total of 679 hot dogs, which is expressed as 56 7/12 dozen.

The local Youth Baseball League served a total of 679 hot dogs using rolls from the grocery store.

If a dozen represents 12 items, we need to calculate how many dozens of rolls were used in this circumstance.

Since 679 hot dogs were served and each dozen contains 12 rolls, we can divide 679 by 12 to find the number of dozens.

Dividing 679 by 12, we get:

679 ÷ 12 = 56 dozens with a remainder of 7.

Therefore, 56 dozen rolls were fully used, with an additional 7 rolls from another dozen.

To express this in mixed number form, it would be 56 7⁄12 dozen rolls.
