D)31,67

Answer:

7

Step-by-step explanation:

Pythagorean Theorem:

25^2=24^2+x

625=576+x^2

49=x^2

x=sqrt49

x=7

Hope this helps!

Merry Christmas!

Answer:

By using the Pythagorean theorem we can solve this

The Pythagorean theorem states that [tex]c^2=a^2+b^2[/tex] where c is the hypotenuse (longest side of the right triangle) and a and b are the other 2 sides. LEts use x to represent the missing side

Therefore,

[tex]25^2=24^2+x^2[/tex]

[tex]625=576+x^2[/tex]

[tex]625-576=576-576+x^2[/tex]

[tex]49=x^2[/tex]

[tex]x=7[/tex]

Answer:

$192.56

Step-by-step explanation:

The keyboard is priced at 1($178.30).

The sales tax is 0.08($178.30) = $14.26

The total cost is thus $178.30 + $14.27 = $192.56

A more efficient way to calculate this would be as follows:

            Total cost = 1.08($178.30) = $192.56

I belive it is 105

Step-by-step explanation:

ok so by spliting this up into where the 9 lengh ends.that recctangle is now 9 by 6,to find area you multiply them,that gets you 54.Now for the other part you want to fill it in,when you do that the area is 6 by 11 what equals 66 but ou have to take away the corner making it 51.Now we add those together and you have 105.

Answer:

i believed its a=-3

Step-by-step explanation:

-2(a-3)=12

-2a+6=12

-2a=6

divide -2

a=-3

Answer:

20

Step-by-step explanation:

55% of x = 11

[tex]\frac{55}{100}*x = 11\\\\x = 11 *\frac{100}{55}\\\\x = 20[/tex]

Answer:

x = 6

Step-by-step explanation:

[tex]\frac{-2}{3}x+9=\frac{4}{3}x-3\\\\\frac{-2}{3}x-\frac{4}{3}=-3-9\\\\\frac{-2-4}{3}x= - 12\\\\\frac{-6}{3}x = -12\\\\ -2x -12\\\\x = \frac{-12}{-2}\\\\x = 6[/tex]

Answer:

y=−x+2

Step-by-step explanation:

x+y=2

Step 1: Add -x to both sides.

x+y+−x=2+−x

y=−x+2

Step-by-step explanation:

x^2+12x-32

factor out the trinomial,

find two numbers that when they multiply,

you get the third term, which is -32,

when you add them,

you get the second term, which is 12.

Answer:

perimeter is sum of all four sides; two of which are '4j' and other two are 60 inches each

Step-by-step explanation:

P= 2(4j) + 2(60)

We know perimeter is 400 inches

400 = 8j + 120

8j = 280

j = 35

Step-by-step explanation:

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins. Bar charts, on the other hand, can be used for a great deal of other types of variables including ordinal and nominal data sets.

Answer:

Tariffs hurt Southerners?

Step-by-step explanation:

In 1828, Congress passed a high protective tariff that infuriated the southern states because they felt it only benefited the industrialized north. For example, a high tariff on imports increased the cost of British textiles. This tariff benefited American producers of cloth — mostly in the north.

Answer:

Step-by-step explanation:

Let the initial price be x

Then the reduced price is

If 5 mugs cost $28.20, we have equation:

Initial price for 1 mug was $7.39

Answer:

so the price for 1 mug was $7.39

Step-by-step explanation:

initial price will be  P

Then the lower price is

x - 1.75

If 5 mugs cost $28.20 then we have to write an equation in order to find the price for 1 mug.

(P - 1.75)*5 = 28.20

P - 1.75 = 28.20/5

P - 1.75 = 5.64

P = 1.75 + 5.64

P = 7.39

Initial price for 1 mug was $7.39

Answer:

y = -2x + 1

Step-by-step explanation:

y = mx + b (m is the slope and b is the y-intercept)

y = mx + 1

Equation for slope: [tex]\frac{y1-y2}{x1-x2}[/tex]

(0,1) (1,-1)

[tex]\frac{1+1}{0-1}[/tex] = [tex]\frac{2}{-1}[/tex] = -2

y = -2x + 1
