Answer:

[tex]\sqrt{47}[/tex] [tex]\sqrt{91}[/tex]

Step-by-step explanation:

The first two are too small to be greater than 6 so those are out.

Any answer with a negative is before 0, so you could rule those out

You are now left with sqrt(47) and sqrt(91)

Step-by-step explanation:

You can use the given (incorrect) equation and fill in the value of t to find h:

 h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet

__

Or, you can use the correct equation, or just your knowledge of revolutions:

 h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet

in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

A. 3.1 feet is the answer i believe.........

Step-by-step explanation:

Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

Percentage is a "number or ratio that can be expressed as a fraction of 100".

According to the question,

An employee earned $860 over the past years. The employee needs to pay 14% for income tax and 3% for state income tax

Find an employee needs to pay in Federal income tax:

[tex]\frac{14}{100}[/tex] × 860 = 120.4

Find an employee need to pay in State income tax:

[tex]\frac{3}{100}[/tex] × 860 = 25.8

In order to find an  employee earn after paying both taxes only if we sum the amount of taxes paid by an employee and subtract from earned amount by past years.

860 - (120.4  + 25.8) =713.8

Hence, Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

Step-by-step explanation:

2(x+5)=30

30÷2=15

15-5=10

x=10

The solution to the equation y = 5x - 5 is given by the ordered pairs

( 0 , -5 ) , ( 1 , 0 ) , ( 2 , 5 ) , ( 3 , 10 ) , ( 4 , 15 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = 5x - 5   be equation (1)

On simplifying the equation , we get

Substitute the value of x = 0 in the equation , we get

y = 5 ( 0 ) - 5

y = 0 - 5

y = -5

So , the ordered pair is ( 0 , -5 )

Substitute the value of x = 1 in the equation , we get

y = 5 ( 1 ) - 5

y = 5 - 5

y = 0

So , the ordered pair is ( 1 , 0 )

Substitute the value of x = 2 in the equation , we get

y = 5 ( 2) - 5

y = 10 - 5

y = 5

So , the ordered pair is ( 2 , 5 )

Substitute the value of x = 3 in the equation , we get

y = 5 ( 3 ) - 5

y = 15 - 5

y = 10

So , the ordered pair is ( 3 , 10 )

Substitute the value of x = 4 in the equation , we get

y = 5 ( 4 ) - 5

y = 20 - 5

y = 15

So , the ordered pair is ( 4 , 15 )

Hence , the equations are solved

Step-by-step explanation:

all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last,  multiply 3 1/2 by 2 and you will geet 7 as your final answer.

The answer would be 7!

You would take 1 and add 1/2 to it

= 1 1/2

Then, multiply by 2

= 3

Then add 1/2 to that

= 3 1/2

Then multiply 2 one more time

= 7

This is because Mai gave half of her brownie and then half more of her brownie to each person she gave it to

So you would add 1 + 1/2 and then multiply by 2

Since she did this to 2 people you would repeat one more time!

Answer:

1) C

2) B

3) A,B, and C

4) C

5) B

6) C

Step-by-step explanation:

Answer:

1. C

2. B

3. A, B, C

4. C

5. B

6. C

Step-by-step explanation:

1. You can remember the name by just looking at their positions- they alternate and they're on the exterior

2. They are supplementary meaning they add to 180°, set the angle measures up to 180 and solve for x!

76 + 2x = 180

2x = 104

x = 52

3. Equilateral trinagles have these qualities

4. Those hashes on the sides of the triangles signify those sides are the same length- that means the angles opposite of those sides share the same angle measure. If you know two angles are 35, and the last angle is 2x, you can set up an equation:

35 + 35+ 2x = 180

70 + 2x = 180

2x = 110

x = 55

5. That square means a right angle which equals  90°, like question 4, you set up an equation!

90 + 5x + 5x = 180

90 + 10x = 180

10x = 90

x = 9

6. Set up a proportion.

12 : 30 // 12(x) = 30, x = 2.5

8 : y // 8(2.5) = y, y = 20

Answer:

34 degrees

Step-by-step explanation:

angles on a straight line add up to 180 degrees so over here the middle angle as we can see is 90 degrees so we add that to the 56 degrees. From adding them we get 146. 180 -146 is 34 degrees and that is our answer. :)
