Answer:

The percent of change is –12.5%.

Answer:

-800%

Step-by-step explanation:

1. you have to do 128-112 and you get 16.

2. you then take 128 and divide by 16 and you should get 8.

3. you take 8 and multiply it by 100 and you should get 800.

4. and since you are going from 128 to 112 you are decreasing so the final number will be negative.

hope this helped!

Given:

Total distance for daily exercise is  [tex]2\dfrac{1}{2}\text{ miles}[/tex].

You run 1/3 of that distance on a hill.

You run down a slope for the last 1/2 of the hill.

To find:

The distance you run down the slope.

Solution:

We have,

Total distance [tex]=2\dfrac{1}{2}\text{ miles}[/tex]

You run 1/3 of that distance on a hill.

Distance on a hill [tex]=\dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]

You run down a slope for the last 1/2 of the hill.

Distance you run down the slope [tex]=\dfrac{1}{2}\times \dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]

[tex]=\dfrac{1}{6}\times \dfrac{2\times 2+1}{2}\text{ miles}[/tex]

[tex]=\dfrac{1}{6}\times \dfrac{5}{2}\text{ miles}[/tex]

[tex]=\dfrac{5}{12}\text{ miles}[/tex]

In cannot be expressed as mixed fraction because 5<12.

Therefore, the distance you run down the slope is [tex]\dfrac{5}{12}\text{ miles}[/tex].

Complete question:

Russell has a collection of 1,200 pennies. Of these pennies, 25% are dated before 1980, 35% are dated from 1980 to 2000, and the rest are dated after 2000. How many pennies in Russell’s collection are dated after 2000?

Answer:

480 pennies

Step-by-step explanation:

Total pennies = 1200

Datwd before 1980 = 25%

Dated 1980 - 2000 = 35%

The rest are Dated after 2000 ;

How many are dated after 2000

Dated before 1980 = 25% ;

25% of 1200

0.25 * 1200 = 300

Dated 1980 - 2000 = 35% ;

0.35 * 1200 = 420

Dated after 2000 ;

1200 - (300 + 420)

1200 - 720

= 480 pennies

Answer:

one solution

Step-by-step explanation:

Answer:

(6, -9)

Step-by-step explanation:

Eliminate y (you can do x too, but y is easier for this problem)

To eliminate y we must get 0y

If one is 2y, the other must be -2y to get to 0

Keep the first equation the same

7x + 2y = 24

Multiply all numbers in the second equation by -2 (so y can be -2y)

-8x + -2y = -30

Positive + Negative = Negative

-8x - 2y = -30

Now add/subtract the two equations from each other

7x + 2y = 24

-8x - 2y = -30

-1x + 0y = -6

-1x = -6

Divide both sides by -1 to isolate variable

-1x ÷ -1 = -6 ÷ -1

x = 6

We could simply plug in the x value into one of the equations, but that's substitution - not elimination. Repeat the same steps for x

I will multiply the first equation by 4 to get 28x and the second equation by -7 to get -28x for an answer of 0x

28x + 8y = 96

-28x - 7y = -105

0x + 1y = -9

1y = -9

Divide both sides by 1 to isolate the variable

1y ÷ 1 = -9 ÷ 1

y = -9

Answer:

2.4 gallons every minute

Step-by-step explanation:

Since we are given three values and one variable that needs to be solved in a ratio problem we can use the Rule of Three to solve for the flow rate of the water with this being represented as x.

4 [tex]\frac{1}{2}[/tex] or 4.5 gallons  <============>  1 [tex]\frac{7}{8}[/tex] or 1.875 minute

     x   gallons   <==============> 1 minute

(1 * 4.5) / 1.875 = x

2.4 gallons = x

Therefore, we can see that the flow rate is 2.4 gallons every minute, meaning that every single minute that the hose is on, it will deposit 2.4 gallons of water into the fish tank.

Answer:

X=6

Step-by-step explanation:

All you do is solve for X.

Answer:

[tex] - 3(x - 1) + 7x = 27 \\ - 3x + 3 + 7x = 27 \\ - 3x + 7x = 27 - 3 \\ 4x = 24 \\ x = \frac{24}{4 } \\ x = 6[/tex]

this is the correct answer you can check

1. (n+9) • (n-6) is the answer

The required, 1. factor of the expression n²+ 3n - 54 = (n + 6)(n - 9), 2. x² - 14x + 49 can be expressed as (x - 7)².

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

3.

To factor the quadratic expression n² + 3n - 54, we need to find two numbers whose product is -54 and whose sum is 3. These numbers are 6 and -9.

Therefore, we can write:

n²+ 3n - 54 = (n + 6)(n - 9)

So the expression (n + 6)(n - 9) is a factor of n² + 3n - 54.

2.

The trinomial x² - 14x + 49 can be expressed as the square of a binomial. Specifically, it is the square of (x - 7):

(x - 7)² = (x - 7)(x - 7) = x² - 14x + 49

Therefore, x² - 14x + 49 can be expressed as (x - 7)².

slope = M = rise/ run

P1=(2,140)

P2=(0,0)  

M= (Y2-Y1) / ( X2-X1)

M = 0-140 /0-2

M = -140 / -2

M = 140 / 2

Yes, Alejandro is right

The slope of the line is the ratio of rise to the run. Therefore the line  with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.

Points of the line are (2,140) and (0,0).

The rise of the line is 140.

The run of the line is 2.

Slope of a line describes the steepness and the direction of the line. The slope of of line passing through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be given as,

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

Thus the slope of the line with points (2,140) and (0,0) is,

[tex]m=\dfrac{(0-140)}{(0-2)} \\ m=\dfrac{140}{2} \\ [/tex]

As the slope of the line is the ratio of rise to the run. Therefore the line  with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
