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:

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.

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.
