The area of a rectangle with width x and length 5x is 5x2. What does the coefficient 5 mean in terms of the problem?
Answers
Answer:
The length is 5 times the width
Step-by-step explanation:
Let
W ----> the width of the rectangle
L ----> the length of the rectangle
we know that
The area of rectangle is equal to
In this problem we have
----> equation A
----> equation B
substitute equation B in equation A
therefore
The length is 5 times the width

Adding two negatives results in a negative
-1/4 = -3/12
-3/12 + -5/12 = -8/12
-8/12 + 3/12 < Subtract and take the sign of the BIGGER number.
8 - 3 = 5
- 5/12
Answer: - 5/12
-5/12 - 1/4 + 3/12
To add fractions, they must all have the same denominator.
Change the -1/4 to twelfths:
-1/4 = -3/12 .
So now the problem is
- 5/12 - 3/12 + 3/12
Notice that the -3/12 and the +3/12 knock each other out,
and all you're left with is
- 5/12 .

18÷2=9
4÷2=2
A. 2 rows can be possible with 9 paintings and 2 photographs in each row.
B. 3 rows are not possible because none of the numbers can be divided by three.
C. 4 rows cannot be possible. While 4 can be divided by 4, 18 cannot.
D. 6 rows cannot be possible because the only number that can be divided by 6 is 18, which would be three. 4 is not divisible by 6.
You were right, the answer is A. with each row containing 9 paintings and 2 photographs!

Answer: Yes, because they are similar triangles
Step-by-step explanation:
Let ABC be the right triangle with vertical side of 3 and a horizontal side of 7.
And, right angle at B,
Then, AB = 3, BC = 7 ⇒ AC = √58
Again let, DEF be the right triangle with vertical side of 9 and a horizontal side of 21.
And, right angle at E,
Then, DE = 9, EF = 21 ⇒ DF = 3√58
Thus, in triangles ABC and DEF,
Therefore,
By the property of similar triangles,
Since, in both triangles horizontal sides BC and EF are on X-axis,
Therefore,
The second one is correct
Answer:
Yes

Final answer:
To calculate interest over time, you need to use the compound interest formula because monthly deposits are being made. However, without more information on how frequently the interest was compounded, we can't find the exact total interest earned from a retirement plan with a 2.5% rate over 42 years with $520 monthly deposits.
Explanation:
The question asks how much interest was gained from investing in a retirement plan with a rate of 2.5% over 42 years. The total monthly deposits were $520. To calculate this, we need to use the simple interest formula which is I=PRT, where 'I' is the interest, 'P' is the principal amount (the initial investment), 'R' is the rate of interest, and 'T' is the period of time.
However, in this case, because the deposits were made monthly, this is not a simple interest problem but a compound interest problem. In such cases, the formula to calculate compound interest (which includes the initial investment amount and the interest earned) is A = P (1 + r/n) ^ nt, where:
- 'A' is the amount of money accumulated after n years, including interest.
- 'P' is the principal amount (the initial amount of money)
- 'r' is the annual interest rate (in decimal)
- 'n' is the number of times that interest is compounded per year
- 't' is the time the money is invested for in years
As we don't have enough information to conclude the precise amount (e.g., whether the interest was compounded annually, quarterly, monthly, or daily), we can't calculate the exact value of the interest earned.
