I think this is right.. I tried my best. If u get it sorry... I’m very sorry
1. Divide 7.20 by 4 since the 4 are the pencils
2.divide 7.20 by 5 ( 5 represents the erasers )
3. Then finally multiply 1.44 from 7.20/5 and
2 and u get 2.88
Answer: D. 7^11
Step-by-step explanation:
For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11
Answer:$1304.89
Step-by-step explanation:
P(1 + r/n)^r*t
500 ( 1 + 0.08/52) ∧ 52*12
500 (1.00154)^624
500 ( 2.61)
1304.88523
Answer:
Step-by-step explanation:
Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.
You would follow the order of operations
Parentheses
Exponents
Multiply/Divide
Add/Subtract
if it is multiply or divide, go from left to right. do the same if it is addition or subtraction
4000/10x2+4-8
first, do 4000/10
400x2+4-8
then do 400x2
800+4-8
then do 800+4
804-8
796
rounding to the nearest tens would make it 800
because 9 rounded up is 10
