Answer:
D - (D/5)
Step-by-step explanation:
Let's imagine that D equals 100 dollars -
Well, we know that to get 20% of an amount, we need to divide the amount by five. So let's do that -
100 / 5 = 20
We now know that 20% of 100 dollars is equal to 20 dollars. We have now finished the first part. On to the second part.
We now need to take away 20% of 100 dollars off of 100 dollars - this is the price of the item after the discount.
100 - 20 = 80 dollars.
We now fit in D instead of 100 dollars -
D - (D/5)
Answer:
m∠B = 31°
Step-by-step explanation:
First, find the measure of angle ACB by subtracting its supplement from 180 degrees:
180 - 113 = 77
m∠ACB = 77°
Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:
m∠B = 180° - 72° - 77°
m∠B = 31°
Answer: Avery's bottle holds 300 milliliters. If Dashawn's container holds 3/4 as much, then his container can hold 225 milliliters. Added together, both containers can hold 525.
Step-by-step explanation: 3/4 of 300 is 225. 300 + 225 = 525.
Answer:
Step-by-step explanation:
k = 4/24 = 1/6
A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
