7? An isosceles triangle has two indentical sides(you can remember that by saying you have TWO eyes hint EYEsosceles) but I’m guessing the bottom is 3 and the two sides are 7?
Answer:
55 degrees
Step-by-step explanation:
Since it's a right angle it's total is 90 degrees, so you'll subtract 35 from 90.
90-35=55
Answer:
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
Step-by-step explanation:
x = amount of 4% fuel
6 - x = amount of 20% fuel
0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals
4x + 20(6 - x) = 8(6)
4x + 120 - 20x = 48
-16x + 120 = 48
-16x = -72
x = 4.5
She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
Answer:
Given: Point C is the center of circle.
To Find: ∠ A CB
Solution: Measure of arc A DB=312°
Angle made by complete circle=360°
⇒∠A DB + ∠ AC B= 360°[Total measure of complete circle]
⇒ 312° + ∠ AC B= 360°
⇒∠ AC B = 360° - 312°
⇒ ∠ AC B=48°
Answer:
20
Step-by-step explanation:
Number of paperback books = 4
Percentage of total books that were paperbacks = 20%
Let total number of books = x
Hence,
20% of total books = paperback books
20% of x = 4
0.2 * x = 4
0.2x = 4
0.2x / 0.2 = 4 / 0.2
x = 20
Total number of books = 20
