Answer:
2.25 (or
) g/mL
<u>Skills needed: Density</u>
Step-by-step explanation:
1) Briefly, let's cover what density is:
- It is 
- Measures the mass per unit of volume
- In this situation the formula for density is: 
--->
is the final mass
--->
is the initial mass
--->
is the final volume
--->
is the initial volume
2) In this case, we start out with a mass of 180 grams as stated in the problem, and also 50 mL of water initially.
This means that:
-
is 180 g
-
is 50 mL
3) Also, we end up with 270 g in mass, and 90 mL of water finally.
-
is 270g
-
is 90 mL
4) We can find density by substitute given the values above:

5) Our answer is 2.25 g/mL (since mass is grams (g), and volume is milliliters (mL) in the problem above).
Answer:
The projected average monthly rent plus maintenance fee is $4,100
Step-by-step explanation:
In the question, we are told that the percentage lease terms state that rent is 2% of sales over $100,000
Since sales is $190,000 projected,
the percentage will be 2% of 190,000
= 2/100 * 190,000 = $3,800
we now proceed to add the monthly maintenance fee
That will be $3,800 + $300 = $4,100
<span>The question is asking us to calculate : 13/56 + 5/7. To do this we have first to find the common denominator for these fractions. We know that 56 = 7 * 8, so the common denominator is 56. Then we will multiply the numerator and the denominator of the second fraction by 8. 5/7 * 8/8 = 40/56. Finally we will add : 13/56 + 40/56 = 53/56 and that is the final answer, which can not be simplified. Answer: 53/56</span>
You got it right. It is D.
