In one year, a dog's weight increased
from 64 pounds to 80 pounds. By what
percentage did the dog's weight increase?

Answer:

  yes

Step-by-step explanation:

  14² +48² = 196 +2304 = 2500 = 50²

The three lengths (14, 48, 50) are a Pythagorean triple.

Additional comment

The two smaller numbers correspond to side lengths. The larger one corresponds to the hypotenuse length.

We typically write the numbers of a Pythagorean triple in increasing order, but the order doesn't really matter. As sides of a triangle, the triangle formed is a right triangle, regardless of the order.

Answer:

Finding the Average Rate of Change of a Function

To find the average rate of change, we divide the change in the output value by the change in the input value. The Greek letterΔ (delta) signifies the change in a quantity; we read the ratio as “delta-y over delta-x” or “the change iny divided by the change inx.

Answer: [tex]x = \frac{3\sqrt{5}}{7}\\\\[/tex]

Explanation:

The equation of the unit circle is [tex]x^2+y^2 = 1\\\\[/tex]

Plug in y = -2/7 and solve for x

[tex]x^2+y^2 = 1\\\\x^2+\left(-\frac{2}{7}\right) = 1\\\\x^2+\frac{4}{49} = 1\\\\x^2 = 1-\frac{4}{49}\\\\x^2 = \frac{49}{49}-\frac{4}{49}\\\\x^2 = \frac{45}{49}\\\\x = \sqrt{\frac{45}{49}} \ \ \text{ ... x is positive}\\\\x = \frac{\sqrt{45}}{\sqrt{49}}\\\\x = \frac{\sqrt{9*5}}{7}\\\\x = \frac{\sqrt{9}*\sqrt{5}}{7}\\\\x = \frac{3\sqrt{5}}{7}\\\\[/tex]

A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.

B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.

how many months for the cost to be the same?

[tex]\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4[/tex]

well, since the cost for both is the same, we can just get A's, knowing that B is the same

[tex]12+28(4)\implies 12+112\implies 124[/tex]

Answer:

x =5.5

Step-by-step explanation:

The directions say to use x for the number.

"take 10 away from"

x - 10

"then square the result"

(x - 10)^2

"I get the same answer" means the two expressions will be equal to each other.

"if I square my number"

x^2

"then subtract 10 from the result"

x^2 - 10

SET EQUAL TO EACH OTHER.

(x - 10)^2 = x^2 -10

Multiply on the left side.

x^2-20x+100 =x^2-10

subtract x^2 from both sides.

-20x + 100 = -10

subtract 100.

-20x = -110

divide by -20

x = 11/2 or 5.5

CHECK:

(5.5-10)^2=20.25

5.5^2 - 10=20.25

The Algebraic equations (x - 10)² and x² - 10 have an equal value My number is 5.5.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, then subtract 10 from the result.

Let the number be x.

If I subtract 10 from my number that is x - 10 then square the result that is (x-10)².

And if I square my number that is x² then subtract 10 from the result that is x² - 10.

Both the result are the same then we have

          (x - 10)² = x² - 10

x² - 20x + 100 = x² - 10

    -20x + 100 = -10

                    x = 5.5

My number is 5.5.

Answer:

16.9% to the nearest tenth of a percent

Step-by-step explanation:

First, find the FINAL sale price (after the additional holiday 5% reduction).

If we wish to reduce $10,500 by 5%, that means the final price is 95% of the before price.  

95% = 95/100 = 0.95

So 95% of $10,500 = 0.95 x 10500 = $9,975

To find the total percent discount, we use the percent change formula:

percent change = (difference between the values ÷ original amount) x 100

=  ((12000 - 9975) ÷ 12000) x 100

= 16.875%

So the total percent discount from the car's initial price to the hoiday sale price is 16.9% to the nearest tenth of a percent.

2644 atoms

Step-by-step explanation:

1983/3 = 661

1983 + 661 = 2644 atoms

Answer:

2644 total N and H atoms

Step-by-step explanation:

N/H is 1/3

N/H = 1/3

N/(1983) = 1/3

N = (1983/3)

N = 661 N atoms

1983 + 661 = 2644 total N and H atoms.

Answer:

Step-by-step explanation:

One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.

For x=0, you have ...

  5 > -5 . . . . . true; the solution space is x < 2.5

__

For x=0, you have ...

  -25 > -5(2.5)

  -25 > -12.5 . . . . . false; the solution space is x > 2.5

_____

Alternate solution

Subtract 5:

  -4x > -10

Divide by -4

Answer:

30 units²

Step-by-step explanation:

Formula to find the area of a triangle is :

Area = [tex]\frac{1}{2}[/tex] × Base × Height

Given that,

Base = 10 units

Height = 6 units

Now let us find the area of the triangle.

Area = [tex]\frac{1}{2}[/tex] × Base × Height

Area = [tex]\frac{1}{2}[/tex] × 10 × 6

Area = [tex]\frac{1}{2}[/tex] × 60

Area = 30 units²
