The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the suppl
tresset_1 [31]

Answer:

135

Step-by-step explanation:

The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle

Two Angles are Supplementary when they add up to 180 degrees.

Two Angles are Complementary when they add up to 90 degrees

Let the angle = x

Supplement of the angle = y

The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle

x - 180 = 3(x - 90)

x - 180 = 3x - 270

Collect like terms

3x - x = 270 - 180

2x = 90

x = 90/2

x = 45

x+ y = 180

45 + y = 180

y = 180 -45

y = 135

A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 5 tables is $52. The total cost to re
riadik2000 [5.3K]

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

1. Multiply the entire first equation by -3.

-3(3c+5t=52)

2. Simplify the equation from above:

-9c-15t=-156

3. Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

4. You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

5. Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

6. Simplify the equation above:

3c+43.75=52

7. Subtract 43.75 from both sides of the equation:

3c=8.25

8. Divide both sides by 3 to get your c value:

c=2.75

Work out the area of this semicircle.Take pie to be 3.142 and give your answer to 2 decimal places 10cm
rosijanka [135]

Answer:

The area of the semi circle  A = 157.1 cm^2

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given radius of circle 'r' = 10 cm</em>

<em>The area of the circle formula </em>

<em>                                 </em>A = \pi (r)^{2}<em></em>

<em>The area of the semi circle formula </em>

                            A = \frac{\pi (r)^{2} }{2}

taking  π =3.142

                           A = 3.142 X \frac{(10)^2}{2}

On calculation , we get

                           A = 157.1 cm^2

<u><em>Final answer</em></u>:-

<em>The area of the semi circle  </em>A = 157.1 cm^2<em></em>
