There was $800 deposited at 9% interest and $400 deposited at 4% interest.
The formula for simple interest is I = prt. Using our information we have:
88 = x(0.09)(1) + (1200-x)(0.04)(1)
88 = 0.09x + 48 - 0.04x
88 = 0.05x + 48
Subtract 48 from both sides:
88 - 48 = 0.05x + 48 - 48
40 = 0.05x
Divide both sides by 0.05:
40/0.05 = 0.05x/0.05
x = 800
1200 - x = 400
i think it is 27 i did 5+4 then i did 9x3 and got 27
Answer:
f(g(2)) = 44
Step-by-step explanation:
g(2) = 3(2) + 1 = 7
Plug 7 into f(x) since g(2) = 7
f(7) = 7² - 5 = 44
f(g(2)) = 44
KJ^2=6^2+3^2
KJ=the square root of 36+9
KJ=square root of 45
kJ= 3 times the square root of 5
The answer is D
To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.
