Answer:
C. Determine the principal square root of both sides of the equation.
Step-by-step explanation:
he needs at least 5800
5800/725
8
so he must sell at least 8 cars
There are only 45 cars on the lot, so that is the max he can sell
Choice C
8<=x<=45
Answer:
0.5%
Step-by-step explanation:
The prevalence rate shows the proportion of people that have a disease in a population and to be able to calculate it, you have to divide the number of people that have a disease by the population:
Prevalence rate=(5/1,000)*100
Prevalence rate=0.005*100
Prevalence rate=0.5%
According to this, the answer is that if there are five cases of H1N1 in the community of 1,000 people, the prevalence rate is 0.5%.
Answer:
Step-by-step explanation:
let the number of bracelet be b
Let the number of necklace be n
If Ashley charges $6 for a bracelet , the total amount charged for b bracelets will be 6b
If she charge $12 for a necklace, the total amount for n necklace will be 12n
If she earned $168 in total, then:
6b + 12n = 168
Divide through by 6
b + 2n = 28
Hence the equation for this situation is b + 2n = 28
Next is to solve for b:
Make b the subject of the formula:
b + 2n = 28
subtract 2n from both sides
b + 2n - 2n = 28 - 2n
b = 28 -2n
Hence the function for b will be b = 28-2n
Answer:
Step-by-step explanation:
<u>We know that:</u>
- 12 ounce box of cereal = $3.84
<u>Work:</u>
- 12/3.84 ounce box of cereal = $1
- => 12/3.84 x 2.49 box of cereal = $2.49
- => 7.78 ounces (Rounded to nearest hundredth) = $2.49
Hence, 7.78 ounces cost $2.49.
