Answer:
2.871*10^9
Step-by-step explanation:
add a decimal point at the end of the number ( 2,871,000,000.) then count how many places it takes to move the decimal point between the first and second number (2.8) then write the rest of the numbers higher than "0" after, giving you the 2.871
to show that the number written is in scientific notation you add 10 to the power of the amount of times you moved the decimal place. In this case, because the decimal point was moved a total of 9 times, it would be 10 to the 9th power (10^9).
Well the answer would be 120=120 and 68=68
Answer:
Step-by-step explanation:
Let J = Jerry's age
Let M = Mary's age = 2J
M - 16 = J + 16
Substitute 2J for Mary's age
2J - 16 = J + 16
2J - J - 16 = 16
J = 16 + 16
J = 32
Jerry is 32.
Mary is twice as old as Jerry.
Mary is 2(32) = 64
Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well
Step-by-step explanation:
First, you must find the radius
<em>80.1 ÷ 3.14 = 25.5</em>
<em>25.5 ÷ 2 = 12.75 <---- radius</em>
Then from that, you find the area
A=πr²
<em>12.75² = 162.5</em>
<em>162.5 × 3.24 = 510.25</em>
