Answer:
22. 18
23. 10
Step-by-step explanation:
22
- you plug the number for the variable into the equation (3(2)²+6
- order of operations say exponents first so you do 2²=4 so you have 3(4)+6
- then you multiple 3•4=12 so 12+6
- finally you add 12+6=18
23
- plug in the number for the variable so 5–(-5)
- so a negative and a minus will make it addition (negative + negative = positive)
- do it is 5+5 which equals 10
The answer is b I'm pretty sure
Answer:
3375
Step-by-step explanation:
The formula for volume is
volume = length x height x width
or in simpler terms (only works for cubes i think)
v = a^3
so we know that the side is 15cm long, so we substitute that back into the equation, so,
3375 = 15 x 15 x 15
or
3375 = 15^3
I hope that this helps you out :)
Answer:
If Avery decides to deposit $7,000 for 5 years, the bank would be the better deal would be bank is offering a rate of 3%
compounded annually
Step-by-step explanation:
In order to calculate which bank would be the better deal If Avery decides to deposit $7,000 for 5 years, we would have to make the following calculation:
simple interest rate of 32%.
Therefore, I= P*r*t
=$7,000*32%*5
=$11,200.
compound interest rate of 3%
Therefore, FV=PV(1+r)∧n
FV=$7,000(1+0.03)∧5
FV=$8,114.
If Avery decides to deposit $7,000 for 5 years, the bank would be the better deal would be bank is offering a rate of 3%
compounded annually
