5x+y=40 This is the standard form.
Answer:
10
Step-by-step explanation:
The radius is the magnitude of the complex number that is the difference between any point on the circle and the center point. A suitable calculator can tell you that magnitude:
║(8+7i) - (2-i)║ = √((8-2)² +(7-(-1))²) = √(36+64) = √100 = 10
The quotient is 13/9 or 1 4/9 or 1.4
Answer:
She used 6.825 pints of withe paint to paint her bedroom walls
Step-by-step explanation:
We know Cathy used 9.1 pints of paint and 1/4 is blue.
first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint
1 - 1/4 = 4/4 - 1/4 = 3/4
Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white
3/4 * 9.1 = 6.825
She used 6.825 pints of withe paint to paint her bedroom walls
Cause 400 divided by 10 is 40
