Answer:
60000 square miles
Step-by-step explanation:
Step 1: Great lakes beginning with consonant: Huron, Michigan, Superior
Great lakes beginning with vowel: Ontario, Erie
Step 2: Estimate the areas to nearest thousand.
Estimation of area of Huron = 23000 square miles
Estimation of area of Michigan = 22000 square miles
Estimation of area of Superior = 32000 square miles
Total area of Great lakes beginning with a consonant = 23000 + 22000 + 32000 = 77000 square miles
Estimation of area of Ontario = 7000 square miles
Estimation of area of Erie = 10000 square miles
Total area of Great lakes beginning with a vowel = 7000 + 10000 = 17000 square miles
Step 3: Difference between the total area of Great lakes beginning with a consonant and the vowel
77000 – 17000 = 60000 square miles
Answer:
3
Step-by-step explanation:
so d=rt is the famous formula.
30= 10r
so it would be 3 pages per minute
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.
From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.
A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in
Answer: D. 252 inches squared, last choice
