Answer:
$90.00
Step-by-step explanation:
40% of What is 36?
40/4 = 10 (10%)
36/4 = 9 (9 is 10% of the answer we are looking for)
Multiply both answers (9 and 10) by each other.
You get 90
Answer:
B) 454.50
Step-by-step explanation:
-25.50 + 480.00 = 454.50
Answer:
18
Step-by-step explanation:
Find the factors of each denominator
2 = 1*2
6 = 2*3
9 = 3*3
The least common multiple is
2*3*3 = 18
The least common denominator is 18
Answer:
Angle STR = 78°
Step-by-step explanation:
So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:
20x + 12 + 10x + 33 = 180
Combine like terms
30x + 45 = 180
Subtract 45 from both sides
30x = 135
Divide both sides by 30
x = 4.5
Now we know the value of x. We just need to plug it into angle STR's given value:
10(4.5) + 33 = angle STR
45 + 33 = angle STR
78° = angle STR
