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
1250 miles. You're given a rate and a time, so you can solve for distance using d =rt
d= 250*5 = 1250
hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175
M= 4
Hope that helps have a great day!
