Answer:
7 & 4/5; 39/5; 7.8
Step-by-step explanation:
the answer can come in many forms, If this is a multiple choice question, I will give you many options of what it could be:
first let's solve it..
<u>13</u> x <u>3</u> = <u>39</u>
1 5 5
this is an improper fraction as of right now, but lets show the other ways it could be written, such as a mixed number.
39 divided by 5 is 7.8, so we know that is one of the possible answers.
but if we do a mixed number, it would be 7 (fraction)
39 - 35 = 4 so the mixed number will be 7 & 4/5
Answer:
The owner will have to pay $ 125 after 2 hours.
Step-by-step explanation:
Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :
((6000 - 5000) / 8) x 1 = X
(1000/8) x 1 = X
125 x 1 = X
125 = X
Therefore, the owner will have to pay $ 125 after 2 hours.
A) it is a function
use the vertical line test
The correct question is
<span>A country's people consume 6.3 billion pounds of candy (excluding chewing gum) per year. Express this quantity in terms of pounds per person per month. Note that the population of the country is 301 million.
we know that
1 billion------------------> 1000000000 </span><span>(Thousand </span>Million)=1 x 10<span>^9
</span><span>then
</span>6.3 billion pounds--------------> 6.3 x 10^9 pounds
[pounds of candy per person per year]=[6.3 x 10^9 pounds]/[301 x 10^6]
[pounds of candy per person per year]=20.93 pounds per person per year
[pounds of candy per person per month]=20.93/12=1.74 pounds per person per month
the answer is 1.74 pounds per person per month
For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21
