Answer:

C

Step-by-step explanation:

Exterior angle property: Exterior angle equal the sum of opposite interior angles.

3x + 7 + 4x + 16 = 100  

3x + 4x + 7 + 16 = 100   {Combine like terms}

7x + 23 = 100     {Subtract 23 from both sides}

7x        = 100 - 23

        7x = 77   {Divide both sides by 7}

         x = 77/7

x = 11

∠B = 3x + 7 = 3*11 + 7

     = 33 + 7

     = 40°

Answer:

Proportional

Step-by-step explanation:

The line is going straight up, this means while x- intercept increase y- intercept also increases making it proportional.

Answer:

x = 9

y = 6

Step-by-step explanation:

Let's set up equations:

x + y = 15

x - y = 3

Let's rearrange one of these equations to use the substitution method:

x - y = 3

Add y to each side:

x = y + 3

Substitute in for x:

x + y = 15

y + 3 + y = 15

Combine like terms:

( y + y ) + 3 = 15

2y + 3 = 15

Subtract 3 from each side:

2y = 12

Divide each side by 2:

y = 6

Substitute this in to find the other variable:

x + y = 15

x + 6 = 15

Subtract 6 from each side:

x = 9

Answer:

x=15

Answer:

125

Step-by-step explanation:

First, solve the exponent:

5^2 = 5x5 = 25

Then solve the rest:

5x25-125

Answer:

125

Step-by-step explanation:

We need to follow PEMDAS (or BODMAS):

This says that we need to do exponents first, so we'll do the square root of 5, giving us 25.

After this we will multiply 5 by 25, giving us the answer of 125.

*The key point in this problem is using PEMDAS (or BODMAS) correctly.

The ratio of cups of water to cups of flour will make the same recipe are :

8:27, 12 :36, 16:45, 20 : 54, 24 : 63, 28 : 72

Ratio is use to show the frequency with which one number is contained in another number. For example, if for every  boy there are five girls. This information can be expressed as 1 : 5.

The ratio of cups of water to flour is 4 : 9. The ratios that would yield the same recipe are ratios that are multiples of 4 and 9

Multiples of 4 = 4. 8, 12, 16, 20, 24, 28, 32, 36, 40.

Multiples of 9 = 9, 27, 36, 45, 54, 63, 72, 81, 90.

Pairs of ratios equivalent to 4:9 = 8:27, 12 :36, 16:45, 20 : 54, 24 : 63, 28 : 72,

Answer:

c is the answer pi/9

Step-by-step explanation:so we have from 1 to 6.28

so 3.14 is there

3 is there

pi/9 is about 1/3 or less than 1 so not in between

pi squared/9 is about 9.something/9 so more than 1 over 1 and in between

Explanation:

We multiply the hourly wage by the number of hours worked to get the total amount earned.

(7.25)*(40) = 290

This is before taxes are applied. So we consider it the gross earnings (as opposed to the net earnings).

Step-by-step explanation:

The number is 1/2, and 1/2 squared is 1/4.

Answer:

Therefore, the answer to 421 divided by 27 calculated using Long Division is:

15

16 Remainder

Step-by-step explanation:

421 = dividend

27 = divisor

Step 1:

Start by setting it up with the divisor 27 on the left side and the dividend 421 on the right side like this:

 2 7 ⟌ 4 2 1

Step 2:

The divisor (27) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

 2 7 ⟌ 4 2 1

Step 3:

Multiply the divisor by the result in the previous step (27 x 0 = 0) and write that answer below the dividend.

       0    

 2 7 ⟌ 4 2 1

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

 2 7 ⟌ 4 2 1

     - 0    

       4    

Step 5:

Move down the 2nd digit of the dividend (2) like this:

       0    

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

Step 6:

The divisor (27) goes into the bottom number (42), 1 time(s). Therefore, put 1 on top:

       0 1  

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

Step 7:

Multiply the divisor by the result in the previous step (27 x 1 = 27) and write that answer at the bottom:

       0 1  

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

       2 7  

Step 8:

Subtract the result in the previous step from the number written above it. (42 - 27 = 15) and write the answer at the bottom.

       0 1  

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

     - 2 7  

       1 5  

Step 9:

Move down the last digit of the dividend (1) like this:

       0 1  

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

     - 2 7  

       1 5 1

Step 10:

The divisor (27) goes into the bottom number (151), 5 time(s). Therefore put 5 on top:

       0 1 5

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

     - 2 7  

       1 5 1

Step 11:

Multiply the divisor by the result in the previous step (27 x 5 = 135) and write the answer at the bottom:

       0 1 5

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

     - 2 7  

       1 5 1

       1 3 5

Step 12:

Subtract the result in the previous step from the number written above it. (151 - 135 = 16) and write the answer at the bottom.

       0 1 5

 2 7 ⟌ 4 2 1

     - 0    

       4 2  

     - 2 7  

       1 5 1

     - 1 3 5

         1 6

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 421 divided by 27 calculated using Long Division is:

15

16 Remainder

Answer:

x=53

Step-by-step explanation:

Parallel lines cut by a transversal mean that the alternate interior angles are congruent. Meaning, 115=62+x

115-62 is 53

Answer:

a) x=56º

b= Angle x is on a line. All lines create linear angles, so together all angles that are on that side of the line = 180º. Since the two lines were parallel we know that the two angle measurements next to x are congruent. So 180=62+62+x.
