A piano has 88 keys. Fifty-two of the keys are white.
How many more white keys are there than black keys?

Answer:

50.265482457436 inches

Step-by-step explanation:

radius = 8 inches

C = 2×pi×r

= 2×pi×8

C = 50.265482457436 inches

Answer:

a

Step-by-step explanation:

180-50

Hey there!

Hope this helps!

x=130

Answer:

8

Step-by-step explanation:

it just is

Answer:

8

Step-by-step explanation:

Convert to a decimal

32%

move two decimal points to the left

0.32

multiply

0.32 times 25 = 8

Answer: y=-(5/4)x+5

Step-by-step explanation:

The parent function of a linear line is y=mx+b where m is the slope and b is the y intercept so:

Y=-(5/4)x+5

alrighty then but yyyyy

Answer:

41.79

Step-by-step explanation:

c = 14 * 100/33.5 = 1400/33.5 = 2800/67

= 41.79104

34 degrees.

If you want to find how much an angle is, first check the original line (aka base). Then (only if the line is a 180 degree line) subtract whatever value is shown (in this case it was 146 degrees so what you would do is subtract 146 from 180 and you would have your answer).

Hope this helps.

7y=14

y=2

hey sorry for stealing this answer but r u guys still online on pad. let? I lost my password so thats why i wasnt able to get online that much

Answer:

x<4

Step-by-step explanation:

x+36 is less than 40

x+36<40

Subtract 36 from both sides

This equation means, that in order for the equation to be true, x must be less than 4.

Answer:

x<4

Step-by-step explanation:

x+36=40

you do 36- 40 and  get 4 then it would be x<4

Answer:

x = -3

hope it's helpful ❤❤❤

THANK YOU.

Hey there!

The answer to your question is "n = -3"

First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"

3n

Next, "5 more" represents addition, so "+ 5"

3n + 5

Finally, "is -4" means it is equal to -4, so "= -4"

3n + 5 = -4

Now that we have our equation, we can solve:

3n + 5 = -4

First, we subtract "5" from both sides of the equal sign:

3n = -9

Lastly, we divide both sides by "3".

n = -3

Have a terrificly amazing day!

Step-by-step explanation:

Don't try to be oversmart The equation is invalid

Answer:

90

Step-by-step explanation:

a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90

Answer: 90 degrees

Step-by-step explanation:

Theorem:

a+b+c=180 degrees

39 degrees + 51 degrees + x degrees = 180 degrees

39 + 51 = 90

180 - 90 = 90

Answer:

Between 25 and -18 is 0.

Between -18 and -12 (in the corner) is again, 0.

Between -12 and -18 (left side corner, bottom) is 5.

Between 0 and -12 (top left corner) is -18.

Between 0 and 5 (top of page) is 25

Between 5 and -12 (bottom right corner) is 0

Between -18 and 25 (middle) is 5

Between -18 and 0 (middle) is -12

Between -12 and 0 (middle-left) is 5

Between -12 and -18 (not corner, but above it) is 25.

Step-by-step explanation:

I don't really have a explanation, other than elimination.

Answer:

Step-by-step explanation: Don't have an explanation except elimination.

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.

a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.

Answer:

b

Step-by-step explanation:

2(h-8)-h=h-16

step 1 distribute 2 to whats in the parenthesis

2h-16-h=h-16

step 2 combine like terms

h-16=h-16

add 16 to each side

h=h

subtract h from each side  

0=0

this would have an infinite amount of solutions

Step-by-step explanation:

Answer: = (-2,3)

Step-by-step explanation:

Here, fixed point = origin = (0,0)

Transformation rule for rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin:

[tex](x,y)\to (-y,x)[/tex]

Then, the image of the point (3,2) =  (-2,3)

Hence, the image of the point (3,2) after a rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)

Answer: The answer is -2,3 because 90 degrees of the orgin :) enjoy

Answer:

8

Step-by-step explanation:

3+2=5

5 x 8 = 5 x 8

Answer:

8

Step-by-step explanation:

2 numbers are in perenticies so do them first 3+2 = 5 Then wait dont do nothing with that do 5x8 to get what to need to get 5 x? to witch is

40 so 8 would be the correct answer

Answer:

E

Step-by-step explanation:

Irrational means cannot be put into a fraction. Or random repeating decimals is how I remember it.

√48 can be simplified to equal 4√3. √3 cannot be put into fraction form.

Answer:

h = 55

Step-by-step explanation:
