Answer:
2
Step-by-step explanation:
There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.
32/4 = 8
Girrafe = 8
Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.
32/8 = 4.
Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.
Now we know girrafes equal 8, and tigers equal 2.
A girrafe - A tiger x 3 = 2
PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.
Answer:
Part A:
Blueprint 10 inches ⇒ Actual 35 feet
Blueprint 20 inches ⇒ Actual 70 feet
Part B:
The cost of the cover is $857.5
Step-by-step explanation:
Part A:
∵ The drawing scale is 2 inches for 7 feet
∵ The length = 20 inches and the width = 10 inches
∴ The actual length = (20 × 7) ÷ 2 = 70 feet
∴ The actual width = (10 × 7) ÷ 2 = 35 feet
Part B:
∵ The cost per square foot = $0.35
∵ The area of the pool = 70 × 35 = 2450 feet ²
∴ The cost of the cover = 2450 × 0.35 = $857.5
Answer:
the answer is 28 for the area.
