Ok, so per month+comission+reimgurssement=total
we jsut want the comission
so total-permonth-reimbursement=comission=256.65-240-8.95=7.7
she made 7.7 comission
$7.70 is 5% of her salse
find 100%
remember that x%=x/100
hmm
7.7 is 5% of total sales
7.7=5/100 of total sales
tiems both sides by 100/5
770/5=total sales
154=total sales
her total sales was $154
ok, you want an equation?
256.65=240+0.05s+8.95 where s is her total sales
Please don't give me credit, but I want to say that;
1. You need a picture attached to this
2. Make sure you add if 5 feet is the length or width, in addition to the 3 feet
3. The width can't be a negative value, so eliminate the negative answers
4. For the second answer, why is there a coma preceding another value? The width can can only be one value
You can add all these elements
Hoped this helped!
The volume of the cylinder is 4710 cubic inches
Step-by-step explanation:
Volume of the cone = 1570 cubic inches
Volume of cone = 1/3(volume of the cylinder)
So,
Volume of the cylinder = 3(volume of the cone)
Volume of the cylinder = 3(1570)
= 4710 cubic inches
The volume of the cylinder is 4710 cubic inches
Hello from MrBillDoesMath!
Answer:
Choice B, -2 sqrt(85) / 85
Discussion:
By definition,
cos(@) = length of side adjacent to angle / hypotenuse
= -2/ ( sqrt ( (-2)^2 + (9^2) ) (usin Pythag. theorem)
= -2/ sqty (4 + 81)
= -2 / (sqrt(85)
Multiply numerator and denominator by sqrt(85):
= (-2 / ( sqrt(85) ) * (sqrt(85)/sqrt(85) )
= -2 sqrt(85) / 85
which is choice B
Thank you,
MrB
