A store buys a shirt from the vendor for $15. The store makes a 55% profit when the shirt is sold to a customer. What is the retail price of the shirt?
Answer:
$23.25
Step-by-step explanation:
Step one:
given data
A store buys a shirt from the vendor for $15
The store makes a 55% profit
Required
The sale price of the shirt
Step two:
Percent profit= sale-cost price/cost price *100
subtitute
55= sale-15/15 *100
0.55= sale-15/15
cross multiply
sale-15= 0.55*15
sale-15=8.25
sale= 8.25+15
sale=$23.25
Chong thinks of a Number adds 10 and then multiplies the number so obtained by 3, and get 42. If the number is n then write an equation for this
Answer:
The equation for this is: [tex]3(n+10) = 42[/tex]
Step-by-step explanation:
We have that the number though is n.
Adds 10:
This means that now we have: [tex]n + 10[/tex]
Multiplies by 3:
This means that now we have: [tex]3(n+10)[/tex]
Gets 42:
This means that: [tex]3(n+10) = 42[/tex]

Answer:
a) $8.73
b) $608.73
Step-by-step explanation:
a) The interest charged is ...
I = Prt
where P is the amount borrowed, r is the daily rate, and t is the number of days.
I = $600×0.04848×30 = $8.73 . . . interest
__
b) The amount repaid is the borrowed amount plus interest.
$600 +8.73 = $608.73 . . . repaid
(x + 2y – 2z) – (2x – 5y – 6z) is equivalent to...?
The Expression (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
(x + 2y – 2z) – (2x – 5y – 6z)
so, (x + 2y – 2z) – 2x + 5y + 6z
= ( x- 2x) + (2y+ y)+ ( 6z- z)
= -x + 3y + 5z
Hence, (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z

4x + 4(3 - 2×) = 2(4x + 2)/4 + 5
Solve this equation
Answer:
x=1
Step-by-step explanation:
Factor out the common term 22.

4x+4(3−2x)=2×

to 2x+12x+1.
4x+4(3-2x)=2x+1+5
Simplify 2x+1+5 to 2x+6.
4x+4(3-2x)=2x+6
Expand.
4x+12-8x=2x+6
Simplify 4x+12-8x to -4x+12.
-4x+12=2x+6
Add 4x to both sides.
12=2x+6+4x
Simplify 2x+6+4x to 6x+6.
12=6x+6
Subtract 6 from both sides.
12-6=6x
Simplify 12−6 to 6.
6=6x
Divide both sides by 6
1=x
Switch sides.

Step-by-step explanation:
What is the slope of a line that is perpendicular to the line with equation 12x+3y=9?
Answer:
The slope would be 1/4.
Step-by-step explanation:
To find the perpendicular slope first you have to set this equation to y
to do this you use the subtraction prop of equality and you will get 12x-9= -3y
then you divide by -3 on both sides to get y by itself
you will get -4x+3=y
now that you know the slope is -4, you must find the negative reciprocal slope of this which means you have to flip the numerator and denominator and make the sign its opposite.
The perpendicular slope would then be 1/4.
Which is the image of P(4, 7) after a translation along < 1, 3 >?
Given:
The point is located at P(4,7).
It is translated along [tex]\left<1,3\right>[/tex].
To find:
The image of the given point after the translation.
Solution:
The point is translated along [tex]\left<1,3\right>[/tex]. So, the rule of translation is defined by:
[tex](x,y)\to (x+1,y+3)[/tex]
The point is located at P(4,7).
Using the above rule, we get
[tex]P(4,7)\to P'(4+1,7+3)[/tex]
[tex]P(4,7)\to P'(5,10)[/tex]
The image of given point after the translation is (5,10).
Therefore, the correct option is A.
Using the following image, determine if the triangles are similar. If so, how?

Find the perimeter of the figure to the nearest hundredth.
Answer:
Perimeter of figure is 31.85 inches
Step-by-step explanation:
We have a rectangle and semi-circle in the figure.
First we will find perimeter of rectangle and semicircle and add them to find perimeter of rectangle.
First find perimeter of rectangle
The formula used is: [tex]Perimeter\: of\: rectangle=2(length+width)[/tex]
We have width = 7 in
length = 5 in
The perimeter is:
[tex]Perimeter\: of\: rectangle=2(length+width)\\Perimeter\: of\: rectangle=2(5+7)\\Perimeter\: of\: rectangle=2(12)\\Perimeter\: of\: rectangle=24\:in[/tex]
The perimeter of rectangle = 24 in
Now, finding perimeter of semi-circle
The formula used is: [tex]Perimeter\: of\: semi-circle=\frac{\pi d}{2}[/tex]
Wee have diameter d = 5 in
So, perimeter is:
[tex]Perimeter\: of\: semi-circle=\frac{\pi d}{2}\\Perimeter\: of\: semi-circle=\frac{3.14\times 5}{2}\\Perimeter\: of\: semi-circle=7.85\:in[/tex]
So, Perimeter of semi-circle= 7.85 in
Now, finding Perimeter of figure
Perimeter of figure = Perimeter of Rectangle + Perimeter of semi-circle
Perimeter of figure = 24 + 7.85
Perimeter of figure = 31.85 inches
So, Perimeter of figure is 31.85 inches
Andrew goes to the shop to buy some apples and bananas.
He goes to purchase 5 apples and 4 bananas, and the total comes to $ 5.70.
Unfortunality, he doesn’t have enough money, so he puts back 1 apple and 2
bananas.
The new total is $ 3.60. What is the cost of 1 apple and the cost of 1 banana?
b. Andrea’s budget is $6. If she buys equal number of apples and bananas, then
what is the maximum number of apples and bananas, she can buy?
Answer:
a. The price of an apple is $0.5 and that of a banana is $0.8
b. 4
Step-by-step explanation:
Form simultaneous equations from the information.
For 5 apples and 4 bananas, and the total comes to $ 5.70 this can be;
5 a + 4 b = $5.70----------i
After he puts back 1 apple and 2 bananas, the equation will be;
4 a + 2 b = $3.60 -------------ii
Solve the two equations simultaneously as;
{5 a + 4 b = 5.70 }4 ---------making the a terms equal to eliminate them
{4 a + 2 b = 3.60}5
20 a + 16 b = 22.80 -------subtract the b terms
20 a + 10b = 18.00
6 b = 4.80
b= 4.80/ 6
b=$ 0.8
Using equation i :
5a + 4b =$5.70
5a + 4*0.8 = 5.70
5a + 3.2 = 5.70
5a = 2.5
a = 2.5 / 5
a=$0.5
The price of an apple is $0.5 and that of a banana is $0.8
b.
Let the number of apples be ------x
Let the number of bananas be-----x
This is because the target is equal numbers;
Form an equation for total cost as;
0.5 x + 0.8 x = $6
1.3 x = 6
x = 1.3 / 6 = 4.62
Maximum number of bananas to buy = 4
Maximum number of apples to buy = 4
However, he will have $0.8 remaining
Which of the following values for x is true for 4x > 10
Answer:
Anything 3 or more
Step-by-step explanation:
3 x 4 = 12.

5 times (6 plus x) = 20
6 plus x = 4
x = 4 - 6
x = -2
Answer:
-2
Step-by-step explanation:
Let the number be x
5 × (6 + x) = 20
6 + x = 20/5
6 + x = 4
x = 4 - 6
x = -2

Which methods could you use to calculate the x-coordinate of the midpoint of a horizontal line segment with endpoints at (0,0) and (20,0)
Check all that apply.
A. Count by hand.
B. Divide 20 by 2.
C. Divide 0 by 20.
D. Divide 20 by 0.
Answer:
A. Count by hand.
B. Divide 20 by 2.
Step-by-step explanation:
The midpoint between two points is found by the mean of their coordinates.
Endpoints at (0,0) and (20,0)
So we have x coordinates of 0 and 20. Their mean is:
[tex]\frac{20 - 0}{2} = 10[/tex]
So we can find both counting by hand, or dividing 20 by 2.
