8x^3y^4(3 sqrt xy) LETTER A :)
Answer:
Step-by-step explanation:
Hour hand = radius = 5.5 in
It will travel one full circle in one day, and 3 full circles in 3 days.
<u>The travel distance is:</u>
- 3C = 3(2πr) = 6*3.14*5.5 in = 103.62 in
Answer:
D. The population of California was approximately two times the population of Florida.
Step-by-step explanation:
California's population was 4 x 10^7= 40,000,000
Florida's population was 2 x 10^7= 20,000,000
So therefore Califirnia's population was approximately two times the population of Florida.
I hope this helps!!
The simple interest formula is A = P(1 + rt) in which A is the total of money after interest, P is your principal (starting) amount, r is the interest rate, and t is the amount of time.
For 1), plug in your variables to get A = 1500(1 + (7/100*1.5)). Simplify, and you'll get A = 1500*1.105, and finally your answer, $1,657.50.
<span>For 2), add your interest and principal amount, then plug in your variables to get 676 = 520(1 + 5r). Distribute to get 676 = 520 + 2600r. Subtract 520 from 676 to get 156 = 2600r, then divide both sides by 2600 to get a rate of 0.06, or 6%.
For 3), add your interest and principal amount, then plug in your variables to get 1599 = 1300(1 + 5.75t). Distribute to get 1599 = 1300 + 7475t. Subtract 1300 from both sides to get 299 = 7475t, and then divide both sides by 7475 to get .04 = t, or a time period of four years.
The other two problems can be solved using the formula and steps described above. If you still need help with them, leave a comment and I will solve those as well. </span>
Answer:
200 miles
Step-by-step explanation:
Set up a cost equation for each plan using x for miles.
Set the equations equal.
Solve for x, the miles.
For a 1 day rental.
Plan A:
C = 0.18x + 30
Plan B:
C = 66
0.18x + 30 = 66
0.18x = 36
x = 36/0.18
x = 200
Answer: 200 miles
