Step-by-step explanation:
Answer:
Angle C = 45 degrees.
Angle D = 30 degrees.
Step-by-step explanation:
Angle C = 45 + 90 = 135 180 - 135 = 45.
Angle D = 180 - 45 = 135 (angle F) 15 + 135 = 150 180 - 150 = 30
Answer:
Hiro should have divided both sides of the equation by b
Step-by-step explanation:
Given the formula for area of a triangle (A) = ½bh, Hiro was expected to solve for h.
To find out where Hiro made a mistake, let's solve for h step by step as it ought to be solved.
Thus,
A = ½ bh
==>Multiply both sides by 2:
2*A = 2 * [½bh]
2A = bh
==>Divide both sides by b:
(2A)/b = (bh)/b
(2A)/b = h
h = (2A)/b
The mistake Hiro made was that he subtracted b from both sides of the equation instead if dividing both sides by b.
Hiro should have divided both sides of the equation by b
The minimum number of rolls would be 6 because there is a 1/6 chance to get 1 the first time, 2 the second time, or 3 the third time and so on.
Answer:
Area of Large Circle = 380.13
Area of Small Circle = 254.47
Area of Sidewalk = 125.66
Step-by-step explanation:
The side walk is just subtracting the smaller number from the bigger one.
The area is just Pi*r^2
