The area of the Pacific Ocean is 63,780,000 square miles. The Atlantic Ocean is 2.27 cross times 10 to the power of 7 square mil
olganol [36]

Answer:

4.11 * 10⁷ square miles

Step-by-step explanation:

Let P = pacific ocean

A = Atlantic ocean

P = 63,780,000 = 6.38 * 10⁷

Since A is 2.27 * 10⁷ square miles smaller than the pacific ocean,

The area of A = 6.38 * 10⁷ - 2.27 * 10⁷

The area of the atlantic ocean = 4.11 * 10⁷ square miles

Mr. Stanley bought a car that was marked down 18%.
Lady bird [3.3K]

Answer:

P=100-0.18

Step-by-step explanation:

Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.

The measures of two complementary angles are in the ratio 2:3. What is the measure of the smaller angle?
Alex_Xolod [135]
Ratio = 2:3
Let smaller angle be 2x
Let bigger angle be 3x
Sum of two complementary angles = 90
2x + 3x = 90
5x = 90
x = 90/5 = 18
Smaller angle = 2x= 2*18 = 36
I hope it is helpful :D
