If an angle is half of its complement, then the measure of the LARGER angle will be

Answers

Answer:

60°

Step-by-step explanation:

Complementary angles sum 90°

a + b = 90°      Eq. 1

b = a/2             Eq. 2

Replacing Eq. 2 in the Eq. 1

a + a/2 = 90

2a/2 + a/2 = 90

3a/2 = 90

a = 90*2/3

a = 60

from the Eq. 2

b = 60/2

b = 30

Check:

from the Eq. 1

60 + 30 = 90

Answer:

60>30

Then

The larger angle is:

60°

Jenny is making tie dyed shirts for her class with her school colors, blue and yellow she used a total of 8 ounces of fabric paint the amount of blue paint is 3 times the amount of yellow make a diagram to show the ratio of blue to yellow paint

Answers

Answer:

The ratio of blue paint to yellow paint is 3:1

Step-by-step explanation:

Let

x -----> the amount of blue paint in ounces

y ----> the amount of yellow paint in ounces

we know that

x+y=8 -----> equation A

x=3y -----> equation B

Solve the system by substitution

Substitute equation B in equation A

3y + y = 8

4y = 8

y = 2

Find the value of x

x = 3(2) = 6

therefore

The amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces

Find the ratio

To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint

x/y = 6/2 = 3/1

That means -----> Of every 4 parts of paint, three parts are blue and one part is yellow.

Answer:

Total interest = A - P = $2,223.00

Total amount = $10,023.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9.5%/100 = 0.095 per year.

Solving our equation:

A = 7800(1 + (0.095 × 3)) = 10023

A = $10,023.00

The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

Susan buys a new computer 1200 dollars.Sales tax is 11%. How much does Susan actually have to pay?

Answers

Start by finding 11% of 1,200. To do so, multiply .11 by 1,200 to get 132. Add 132 to 1,200 to get 1,332.

In short, Susan has to pay *$1,332*

The amount that Susan actually have to pay should be considered as the $1,332.

Calculation of the amount:

Since the purchase price of the computer is $1,200

And, the sales tax rate is 11%

So here the total amount be like

= $1,200 + 11% of $1,200

= $1,200 + $132

= $1,332

hence, The amount that Susan actually have to pay should be considered as the $1,332.
