The number that 18 is 45% of 40.
To find the number that 18 is 45% of, we can set up the following equation:
we can set up the following equation:
Given number is 18 and the percentage is 45%
18 = 0.45 * x
x=18/0.45
To solve for x, divide both sides of the equation by 0.45:
To solve for x, divide both sides of the equation by 0.45:
x = 18 / 0.45
x=40
By future Performing the calculation:
x = 40
We get the answer as 40.
Therefore, 18 is 45% of 40.

The Answer Is:
c. 4.5102
Answer: 4
Step-by-step explanation:
The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.
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.
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:
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.

The area of the trapezoid is 25 square centimeters.
An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.
Given:
A trapezoid has bases that measure 9 cm and 5 cm.
The height of the figure is 4 cm.
The area of the trapezoid,
= The sum of the bases by 1/2 x height of the trapezoid
= 1/2 (9 + 5) x 4
= 13 x 2
= 25 square centimeters.
Therefore, the area is 25 square centimeters.
