10•b=120
Step-by-step explanation:
10•b=120 is the equation your looking for, if your trying to find out what the variable equals then b=12
Answer: 36 in²
Step-by-step explanation:
A=length times width
4.5 times 8 = 36
The answer would most likely be the first, second, and the third option.
The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.
<span>The charity needs at least 1001 entries to raise more than $25000.
Let n be the number of race entries, i be the income of the race, and c the cost of the race.
The money that the 5K brings in is given by
i = 25 * n + 5000
The cost is given by
c = n * 5
Now if the charity needs to raise more than 25000 then the income minus the cost must be greater than 25000.
25000 < i - c
subsituting for i and c
25000 < i - c = (25 * n + 5000 ) - (5 * n)
simplifying results in
25000 < 25*n - 5*n + 5000
25000 < 20*n + 5000
20000 < 20*n
1000 < n
The number of entries must be greater than 1000. Since entries must be an integer the charity needs at least 1001 entries.</span>
