The art supply store is having a sale. Paint sets are 20% off and everything else is 15% off. Before the discount, a paint set is priced at $43.50, a canvas is $12.75, and paint brushes are $7.50. Mary purchases all three of these items. About how much did Mary spend after the discount, before sales tax? Group of answer choices
Answer:
Step-by-step explanation:
Step one:
given
paint set= $43.50
20% off 43.50
20/100*43.50
0.2*43.50
=$8.7
43.5-8.7
new price of paint set=$34.8
canvas=$12.75
15% off 12.75
15/100*12.75
0.15*12.75
=1.9125
=12.75-1.9125
new price of canvas=$10.83
paint brushes are $7.50
15% off $7.5
15/100*7.5
0.15*7.5
=1.125
=7.5-1.125
new price of paint brush=$6.38
total =$34.8+$10.83+$6.38= $39.25
Answer:
actually the answer is 52
Step-by-step explanation:
20% x 43.50/100 = 34.8
12.75 x 15% /100 = 10.83
7.50x 15%/100 = 6.37$
Add all of them together and you will get 52$
Easiest way to do it
20% x 43.50/100
12.75 + 7.50 = 20.25
20.25 x 15%/ 100 = 3.03
20.25 - 3.03 = 17.21
Then add all of them together and you will still end up with about 52$
17.21 + 34.8 = 52
Leroi and Sylvia both put $300 in a savings account. Leroi decides he will put in an additional $60 each week. Sylvia decides to put in an additional 20% of the amount in the account each week. Complete the sentence to answer the question.
Answer: See explanation
Step-by-step explanation:
Here is the remainder of the question:
a. Who has more money after the first additional deposit? Explain.
b. Who has more money after the second additional deposit?
a. Amount put in savings account = $300
Leroi's amount after first week = $300 + $60 = $360
Sylvia's amount after first week = $300 + (20% × $300) = $300 + (0.2 × $300) = $300 + $60 = $360
They both have equal amount after the first week.
b. After the second deposit,
Leroi's saving = $360 + $60 = $420
Sylvia's saving = $360 + (20% × $360) = $360 + $72 = $432
Sylvia has more savings after the second week

A candle has been burning for 20 min and is now 25 cm tall. In an hour it will be 10 cm tall. Which equation models the height y of the candle in centimeters, x minutes after it was lit?
Answer:
(y - 25) = - 0.25(x - 20)
Step-by-step explanation:
Given that :
Height of candle after burning for 20 minutes = 25 cm
Height after burning for 1 hr (60 minutes) = 10 cm
Height (y) in cm of candle x minutes after being lit:
Using the equation :
(y - y1) = m(x - x1)
m = (change in y / change in x)
Change in height within 60 minutes :
Height at 20 minutes = 25cm
Height after an hour = 10
Change in height per hour = (25 - 10) = 15cm
Hence, m = change in height per minute
15cm / 60 = 0.25cm ( - 0.25) (decrease in height)
y1 = 25 ; x1 = 20
(y - y1) = m(x - x1)
(y - 25) = - 0.25(x - 20)

Explain, in your own words, how to solve the problem shown. When finished explaining the steps, write your answer. There are 4,050 newspapers to be delivered in a certain area of town. If 18 newspaper carriers are all delivering the same number of papers, how many will each deliver?
Answer:
225
Step-by-step explanation:
Total number of newspapers to be delivered = 4050
Total number of carriers to deliver the newspapers = 18
Each newspaper carrier delivers the same number of newspapers.
To find:
The number of newspapers that each newspaper carrier will deliver ?
Solution:
The solution to this problem lies in the language of the problem itself.
As we are given that every newspaper carrier will deliver the same number of newspapers.
Therefore, we need to divide the total number of newspapers i.e. 4050 in 18 (number of newspaper carriers) equal parts.
So, the answer is:
[tex]\dfrac{4050}{18} = \bold{225}[/tex]

What is the contrapositive of the following conditional?
If the Crawford Mustangs do not win the championship, then people do not celebrate.
Answer:
To form the contrapositive of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. The contrapositive of "If it rains, then they cancel school" is "If they do not cancel school, then it does not rain."

how do you graph x - y < 4
Answer: y > -4 + x
Step-by-step explanation: graph the inequality by finding the boundary line
Answer:
y > -4 + x
***(see graph below)****
Step-by-step explanation:
Graph
x − y < 4
Solve for y
Subtract x from both sides of the inequality.
−y < 4 − x
Multiply each term in −y < 4 − x by −1
Multiply each term in −y < 4 − x by −1. When multiplying or dividing both sides of an
inequality by a negative value, f lip the direction of the inequality sign.
(−y) ⋅ −1 > 4 ⋅ −1 + (−x) ⋅ −1
Multiply (−y) ⋅ −1.
Multiply −1 by −1.
1y > 4 ⋅ −1 + (−x) ⋅ −1
Multiply y by 1.
y > 4 ⋅ −1 + (−x) ⋅ −1
Simplify each term.
Multiply 4 by −1.
y > −4 + (−x) ⋅ −1
Multiply (−x) ⋅ −1.
y > −4 + x
Find the slope and the y-intercept for the boundary line.
Rewrite in s lope-intercept form.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Reorder −4 and x. y > x − 4
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y = mx + b. m = 1
b = −4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 1
intercept: (0, −4)
Graph a dashed line, then shade the area above the boundary line since y is greater than −4 + x. y > −4 + x

Answer:
x = 17
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
6x - 15 + 4x - 7 + 2x - 2 = 180, that is
12x - 24 = 180 ( add 24 to both sides )
12x = 204 ( divide both sides by 12 )
x = 17
Write an algebraic expression for the word phrase.
10 times the product of g and h
Answer:
10(g*h)
Step-by-step explanation:
the * is supposed to mean times/multiply
since it is an expression you do not put y= or f(x)= or anything like that
Answer:
10(g*h)
Step-by-step explanation:
"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of the parenthesis as that implies multiplication.

A park in the shape of a rectangle is 18 miles long and 24 miles wide. How much shorter is your walk
if you walk diagonally across the park instead of along the two sides of it?
Answer:
18² + 24² = x²
900 = x²
x = 30
18 + 24 = 42
42 - 30 = 12
Its shorter for 12 miles
Answer:
12 miles less
Step-by-step explanation:
18+24=42
If you walk in a L shape you walk 42 miles
If you walk diagonally:
ABC Right triangle
We have A and B (18 and 24)
Using the pythagorum theorem
a^2+b^2=c^2
18^2+24^2=C^2
324+576=C^2
900=C^2
Square root of 900=C
30=C
You would walk 30 miles
42-30=12
By walking diagonally, you would walk 12 miles less than going all the way around.

What is the length of the diagonal of the square shown below? 11 45° 11 11 90° 11
A. 121
B. 11
C. 11√11
D. √11
E. 11√2
F. √22
Answer:
It would be 11
Step-by-step explanation:
The square's diagonal length is; (E) d = 11√2.
What is a diagonal?A diagonal is a line segment that connects two vertices (or corners) of a polygon also, connects two non-adjacent vertices of a polygon.
This connects the vertices of a polygon, excluding the figure's edges.
A diagonal can be defined as something with slanted lines or a line connecting one corner to the corner farthest away.
A diagonal is a line that connects the bottom left corner of a square to the top right corner.
So, we need to determine the length of the square's diagonal.
The formula for the diagonal of a square is; d = a2; where 'd' is the diagonal and 'a' is the side of the square.
Now, d = 11√2.
Hence, the square's diagonal length is (E) d = 11√2.
