Answer:
The simpler way is:
SP = 0.85*RP
Step-by-step explanation:
Suppose that we have a given amount A. and now we take a given percentage, X%, off.
The new amount will be:
New amount = A - (X%/100%)*A = A*(1 - X%/100%)
This is the general formula.
In this case, we know that the store has advertised 15% off, then we have X% = 15%
Then if:
SP = sales price
RP = regular price
We will have the equation:
SP = RP - (15%/100%)*RP = RP - 0.15*RP
This is what Jill found, but if we use the general equation above, we will find that:
SP = RP*(1 - 15%/100%) = RP*(1 - 0.15) = RP*0.85
So we just need to multiply the regular price by 0.85 to get the sales price.
Answer:
1 in. is the answer.
Step-by-step explanation:
Solution: A Rectangle ABDE in which DE=4 inches and BD= 6 inches
There are two kinds of rotations
1. one along the Breadth, side having length 6 inches,i.e rotated along line GH, Cylinder Z is created.
Radius of cylinder Z=6/2= 3 inches
2. Second along the Length, Side having length 4 inches,i.e rotated about a line CF, cylinder Y is created.
Radius of cylinder Y= 4/2= 2 inches
Difference in Radii= Radius of cylinder Z - Radius of cylinder Y
= 3 - 2= 1 inches
Diagram shown below of both the cases:
Answer:
The number of adults tickets and student tickets purchased is 5 and 3.
Given that,
Tickets to a movie cost $7.25 for adults and $5.50 for students.
A group of friends purchased 8 tickets for $52.75.
Here we assume the no of adult tickets and no of student tickets be x and y.
Based on the above information, the calculation is as follows:
7.25x + 5.50y = 52.75 .............(i)
x + y = 8
x = 8 - y..................(2)
Now put the x value in the equation (1)
So,
7.25(8-y) + 5.50y = 52.75
7.25 × 8 - 7.25y + 5.50y = 52.75
58 - 1.75y = 52.75
5.25 = 1.75y
y = 3
So,
x = 8 - 3
= 5
Therefore we can conclude that the number of adults tickets and student tickets purchased is 5 and 3.
-Hope this helps<3
Its {3, 3, 6, 7, 9}
because the difference in values of 6 and the other numbers are the same as difference between 5 and the other numbers in { 2, 2, 5, 6, 8}
-1 1/4 as a decimal would be -1.25.
Since -1 is a whole number we would just write that as -1. 1/4 as a decimal is .25.
