Answer:
62.5.
Step-by-step explanation:
Given:
The expression to simplify is given as:
55 - 4.5 +12
We have to use PEMDAS method in order to simplify this.
P stands for parenthesis, E for exponents, M/D stands for Multiplication or Division and A/S stands for Addition or Subtraction.
P has the highest priority followed by E followed by M or D which ever comes first followed by A or S which ever comes first.
Here, the first operation we encounter is subtraction S.
First, we will subtract 4.5 from 55. So, 55 - 4.5 = 50.5
Next operation is addition A.
Now, we will add the result to 12. So, 50.5 + 12 = 62.5
Therefore, the answer is 62.5.
Answer:
3
Explanation:
3^2 is equal to 9, and 4^2 is equal to 16, so sqrt(10) must be in between 9 and 16. Since 10 is closer to 9 than to 16, sqrt(10) is closer to 3 than 4, which means that to the nearest integer sqrt(10)=3
Answer:
The amount of interest earned for the year is $37.7
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents principal or amount invested.
T represents the time
R represents the interest rate
I represents the interest
From the information given,
You want to put $580 into a saving account for 1 year. This means that
P = $580 and
T = 1 year
R = 6 1/2 = 6.5%
I = (580× 6.5×1)/100 = $37.7
Answer:
- 3x + 6 = 12; Distributive Property
Step-by-step explanation:
<u>The next step is:</u>
- 3*x + 3*2 = 12
- 3x + 6 = 12
This is a distributive property
Correct choice is A
After first week pond will be:
10 + 10* 0.03 = 10*(1.03) feet deep
after second week it will be:
10*(1.03) + 10*(1.03)*0.03 = 10*(1.03)^2
from this we can conclude that after x week its will be:
10*(1.03)^x
Note that when second week starts our starting pond is already greater by 3%. every week we add 3% of prevous weeks size of pond
for x = 8 we get
f(x) = 10*(1.03)^8 = 12.66 or rounded 13 feet
Answer is D.
