Answer:
α = 62°
β = 56°
gamma = 90°
Step-by-step explanation:
ΔAOB is isosceles, so m∠A = m∠ABO = 28
28 + 28 + m∠AOB = 180
m∠AOB = 180 - 28 - 28 = 124
β = 180 - 124 = 56
arcAB = 124
ΔBOC is isosceles. α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62
∠D is inscribed in a semicircle
m∠D = gamma = 90°
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
Answer:
$23.87
Step-by-step explanation:
Start by finding out how much one book costs-
$20.46/6=3.41
Then find out how much seven books cost- 3.41 (7)=$23.87
The answer is 1.6
How I figured it out:
I divided 8 by 5, which gave me 1.6
To make sure this was right, I multiplied 1.6 by 5, which gave me an answer of 8 or other known as 8 inches.
In conclusion, the number of inces per hour is 1.6
Answer:
x=3 and 9
Step-by-step explanation:
; x-3=0
x=3 (change side change mark)
and
change side change mark.
So, x=9
If u wanna check the answer you can check by substitution x=3 and 9 in equation.
hope it helps you ☺️
