Jill is shopping at a department store that is having a sale this week. The store has advertised 15% off certain merchandise. Jill calculates the sales price by multiplying the regular price by 15% and then subtracting the amount from the regular price:SP = RP - 0.15(RP), where S = sales price and R = regular price. Find a simpler way for Jill to calculate the sales price as she shops.
Will mark brainliest please show your work
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:SP= 0.85RP

i had this question i got it right :)
I need the area and perimiter.
Answer:
189.3 square inches, 55.7 inches
Step-by-step explanation:
Area = area of rectangle + area of semicircle
area of rectange = 10 * 15 = 150 square inches
radius of semicircle = 10/2 = 5
area of circle = (pi * 5^2)/2 = 12.5pi square inches
total area = 150 + 12.5pi = 189.3 square inches
total perimeter = perimeter of rectangle - left side + perimeter of semicircle
perimeter of rectangle = 10 + 15 + 15 = 40 inches
perimeter of semicircle = 10pi/2 = 5pi inches
total perimeter = 40 + 5pi = 55.7 inches

what is 213,548 to the nearest hundreds
Answer:
Step-by-step explanation:
5 is in the hundreds place.
The answer should be 213500
Answer:
Step-by-step explanation:
"to the nearest hundreds" requires rounding off the hundreds place. We get 213,500 because the 48 is less than 50, indicating rounding down.

This question asks to find the capacity of the container. This is essentially asking what the volume of the container is. This can be done by multiplying the length by the width by the height.
4 * 2 * 3
= 24
b)
This question is asking how much material was used to make the prism. This is essentially asking what the surface area of the prism is. This can be found by finding the area of all the sides of the prism and then adding it up. Since it is a rectangular prism, opposite faces are congruent, hence one only has to find the area of three faces, add it up, then multiply it by two to find the answer.
2 ( 4 * 2 ) + 2 ( 3 * 4 ) + 2 ( 2 * 3 )
= 2(8) + 2(12) + 2(6)
= 16 + 24 + 12
= 52
LOGIC PROBLEM
3. CALL TO ORDER
by MARY MARKS CEZUS Sally was just about to complete her first week as a waitress with no major problems when in walked four of her friends. Each ordered a different sandwich, drink, and salad. To test her logic and her waitressing skills, they gave their order to Sally as clues. Sally successfully placed their orders in front of them within a few minutes. Can you, too, match each friend's name (one is Mike), sandwich, drink, and salad (one is a fruit salad)?
1. The four orders are Kathy's, the one with a hamburger, the one with a cola, and the one with the tossed
salad. 2. Linda does not want the tuna melt. 3. Jeff, the person who wants the lemon-lime drink, and the person who wants the grilled cheese, all three think
this is great fun. 4. The orange drink does not go with the potato salad. 5. Jeff wants neither the cola nor the tuna melt. 6. The tossed salad does not go with the chicken fillet. 7. Linda and the person who ordered the grilled cheese are going shopping after lunch. 8. Neither the coleslaw nor the root beer go with the hamburger. 9. The coleslaw goes with neither the chicken fillet nor the lemon-lime. .

What is the value of x?
Enter your answer in the box.
Answer:
x = 47
Step-by-step explanation:
KY + YV = KV
KY + 22 = x
KY = x - 22
By angle bisector property:
[tex] \frac{TK}{TV} = \frac{KY}{YV} \\ \\\frac{87.5}{77} = \frac{x - 22}{22} \\ \\ x - 22 = \frac{87.5 \times 22}{77} \\ \\ x - 22 = \frac{1,925}{77} \\ \\ x - 22 = 25 \\ \\ x = 25 + 22 \\ \\ x = 47[/tex]

Use substitution to solve the system of equations
Answer: 3.75, 5.5
Step-by-step explanation:
The Groves basketball team did not record how many baskets were made by each player during the last game. Daniel remembers that he made three times as many baskets as Ben. Max knows that he made six more baskets than Ben. Mitchell is sure that he made fewer baskets than Ben. Christion is sure that he made the same number of baskets as Mitchell. Altogether the five players made 40 baskets. How many baskets did each player make?
Answers:
Ben = 6Max = 12Mitchell = 2Christion = 2Daniel = 18Each count above refers to the number of baskets made for the given player.
====================================================
Explanation:
For each player, let the following variables represent how many baskets were made
B = BenM = MaxT = MitchelC = ChristionD = DanielSo for example, if D = 10, then this means Daniel made 10 baskets. Though for now, we're not sure what number replaces D or any given letter.
------------------
"Daniel remembers that he made three times as many baskets as Ben" tells us that D = 3B is one equation
We know another equation is M = B+6 since Max made six more baskets than Ben
Another equation is C = T because these two students (Christion and Mitchell) made the same number of baskets.
We also know that T < B since Mitchell made fewer baskets compared to Ben.
Altogether the boys made 40 baskets total, so B+M+T+C+D = 40
-------------------
We have these five mathematical statements
D = 3BM = B+6C = TT < BB+M+T+C+D = 40Let's focus on the last equation
B+M+T+C+D = 40
B+M+T+C+3B = 40 .... plug in D = 3B
4B+M+T+C = 40
4B+M+T+T = 40 .... plug in C = T
4B+M+2T = 40
4B+B+6+2T = 40 .... plug in M = B+6
5B+6+2T = 40
5B+2T = 40-6
5B+2T = 34
Now let's solve for T
5B+2T = 34
2T = 34-5B
2T = -5B+34
T = (-5B+34)/2
T = (-5B)/2 + 34/2
T = -2.5B + 17
----------------------------------
We've eliminated everything but two variables at this point.
Let's say that x replaced B and y replaces T
We get the equation y = -2.5x + 17
If you graph this equation along with y = x, you'll find that the two equations intersect at roughly (4.857, 4.857)
Since we want T < B, this means we want y < x to be the case. The line y = -2.5x+17 goes downhill as we move from left to right. If x is smaller than 4.857, then x >= y. Otherwise, if x is larger than 4.857, then y < x
Furthermore, looking at a table of values for this equation shows that only (x,y) = (6,2) is a point on y = -2.5x+17 such that both x and y are positive and x is the larger value, and they are both integer coordinates.
All of this means that when B = 6, this pairs with T = 2. No other number pair is possible for these two students.
We then use this to find the other player's basket count
D = 3B = 3*6 = 18M = B+6 = 6+6 = 12C = T = 2----------------------------------
So we have the following results
B = 6M = 12T = 2C = 2D = 18As a check,
B+M+T+C+D = 6+12+2+2+18 = 40
which confirms our answers.

Answer:
Ben: 6Daniel: 18Max: 12Mitchell: 2Christion: 2Step-by-step explanation:
Let x and y represent baskets made by Ben and Mitchell, respectively. Then Daniel made 3x baskets, Max made (x+6) baskets, and Christion made y baskets. The total number is ...
x + 3x +(x+6) +y +y = 40
5x +2y = 34 . . . . . . . . . . . subtract 6
The other constraint on the solution is ...
y < x . . . . . . . . . Mitchell made fewer baskets than Ben
__
We can see that 34 differs from a multiple of 5 by an even number, so (by inspection) we determine that (x, y) = (6, 2) is a solution to the equation. (It is also a solution to the inequality.)
Other possible solutions will require y increase by 5 as x decreases by 2, so those are ...
(x, y) = {(6, 2), (4, 7), (2, 12), (0, 17)}
The only (x, y) pair that satisfies the inequality is the first one: (x, y) = (6, 2). Hence the numbers of baskets are ...
Ben: 6Daniel: 18Max: 12Mitchell: 2Christion: 2The value of 34 + 5.5 = . (1 point) 교

Find the volume of the triangular prism.
Answer:
595
Step-by-step explanation:
So, the first step in solving this problem is finding the area of the base. To do this, we can split the triangle into halves, making two triangles with legs 5 and 7. Now, we just need to find the area for one triangle, and then multiply it by 2. The area of one triangle with legs 5 and 7 is 17.5, because (5*7)/2 is the formula for finding the area of the triangle. Now, we need to multiply the area of this triangle by 2 to get the area of the full triangle. 17.5*2 = 35, so the area of the base of the triangular prism is 35. Now, all we have to do is multiply the base by the height. Eventually, multiplying 35 * 17, we get 595.
