Answer:
18
Step-by-step explanation:
We can use a proportion to find out the number of teachers that are needed.
3/70 = x/14,700
70x = 3 * 14,700
70x = 44,100
x = 630
630 teachers are needed altogether. Since there are already 612 teachers, the number of more teachers who are needed is the difference between 630 and 612.
630 - 612 = 18
Answer: 18
The answer is 16.
First of all, you need to divide 4 by 1/4.
4/1 / 1/4 = 1.
15 - 1 + 2
Next, you go from left to right with addition and subtraction, so subtract 1 from 15 first.
15 - 1 = 14
14 + 2
Finally, add 14 and 2.
14 + 2 = 16.
The area of the square whose sides is s inches long will be given by:
Area=length×width
Length=s inches
width=s inches
thus:
the area of the squares will be:
Area=s×s=s² sq. inches
Thus the correct answer is:
area=s² sq. in
Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
