Answer:
1/15
Step-by-step explanation:
Answer:
1/15
Step-by-step explanation:
Lets simplify, since we need to account for the double negative:
-1/3 + 2/5 = 1/15
If an angle is half of its complement, then the measure of the LARGER angle will be
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
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.

A(1, 4), B(3, -2), C(4, 2)
To find
Coordinates of the image A'B'C' after a reflection over the x-axis
Solution
Rule for reflection over x-axis is
R(x) = (x, y) → (x, -y)
The coordinates will change as follows
A(1, 4) → A'(1, -4)
B(3, -2) → B'(3, 2)
C(4, 2) → C'(4. -2)

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.
