Since there are 100 cents in a dollar, routing to the nearest cent would be rounding to the nearest hundredth. In order to do that you would solve to the thousandths place the use that number to round up or down to the nearest hundredth.
For example:
If a dozen roses cost $12.35, how much does each rose cost?
12.35 ÷ 12 = 1.029
The 9 is in the thousandths place. If it is 5 or higher we round the hundredths place up, so our answer is each rose costs 1 dollar and 3 cents ($1.03)
Answer:
about 520,000
Step-by-step explanation:
Following directions, we evaluate the equation by putting the value where the variable is and doing the arithmetic.
__
The value of x will be the number of days between May 26 and May 12. That value is ...
x = 26 -12 = 14
Then the number of mosquitos is estimated to be ...
y = 230,000(1.06^14) ≈ 520,008
About 520,000 mosquitos will inhabit the city on May 26.
_____
<em>Additional comment</em>
Typically, an "estimate" is one or two significant figures. So, 520,000 is a reasonable estimate. 520,008 has more precsision than can be justified.
Answer:
6k +19
Step-by-step explanation:
7k-k+19
Combine like terms
7k-k = 6k
The expression becomes 6k +19
Answer: 11
Step-by-step explanation: m<2 is equal to 42. This also means that 3x+9 is equal to 42.
3x+9=42, solve for x. Subtract 9 from both sides. 3x=33, divide by three to get X isolated. X= 11
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing.
I = PRT
I / P = RT to divide both sides by P
I / PT = R to divide both sides by T
So I / PT = R (the first choice) is the equation solved for R.
