Find the selling price for each item given the cost and
the percent of markup or discount.
36. tennis shoes: $85; 24% discount
Answer:
$64.60
Step-by-step explanation: I believe this is right if not sorry. The first step is to multiply $85 by .24 and that is $20.40. Then take $20.40 from $85 (85-20.40) which is $64.60

How would you do this maths question?
Answer:
Step-by-step explanation:
First you take the 142+B=180
because those 2 are supplementary
B=38
and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.
and a triangle= 180 degrees
A and E are the same so A=E
180-B(38)= 142
and because A=E you do 142/2= 71
and now that you have A and E you don't need A or B for the last part so
E+(x)=180 because those two angles are supplementary.
and E is 71 so...
71+(x)=180 ---------180-71=x
X=109

Can someone help me on this please? X/4=-12 this says x divided by 2 equals -8. Explain how you would solve for x and what you would get.
Answer:
-48 ; - 16
Step-by-step explanation:
Given the expression :
X /4 = - 12
Multiply both sides by 4
X/4 * 4 = - 12 * 4
X = - 48
For the second :
X/2 = - 8
Multiply both sides by 2
X/2 * 2 = - 8 * 2
X = - 16

Nerissa has 5 pink bows, 1 blue bow, and 4 purple bows in a box. She will randomly choose 1 bow from the box.
What is the probability Nerissa will choose a purple bow?
Answer:
[tex] \frac{4}{10} [/tex]
Step-by-step explanation:
Add all the bows together to get your total amount of bows, 5+1+4=10
this will be your demoninator.
there is 4 purple bows so that will be your numerator.
[tex] \frac{purple \: bows}{total \: number \: of \: bows} [/tex]
Probability can be answered as fraction, decimal and percentage..
Answer:
0.4 or 40%Step-by-step explanation:
Probability = favorable outcomes / total outcomes
Total number of bows:
5 + 1 + 4 = 10Number of purple bows:
4Probability of choosing a purple bow:
4/10 = 0.4 or 40%What property of operations can be used to justify that the two expressions in this equation are equivalent? 6x^2 +4x=4x + 6x^2
Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is : [tex]$6x^2 + 4x=4x+6x^2$[/tex]
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.

In a scientific journal, we read that a certain substance weighs 0,000,418 grams.
Write this number in scientific notation.
Answer:
4.18 × 10^ 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
I am assuming that number began with a decimal point.
Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes

The area of the circle is equal to 144π square inches.
What is the area of the circle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,
Area of circle = πr²
Circumference of the circle = 24π
2πr = 24π
r = 12
The area of the circle will be calculated as:-
Area = πr²
Area = π x ( 12 )²
Area = 144π square inches.
Hence, the area is 144π square inches.

Answer:
height= 30 area= 2160
Step-by-step explanation:
I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)
Then, to find area the formula is a=b*h
You already have the base in the image and you already calculated the height
Again, I don't know if this is right. It's not the same as how I do it here
Answer:
h = 15, A = 540
Step-by-step explanation:
Since the 2 legs are congruent then h is a perpendicular bisector, dividing the triangle into 2 right triangles.
Using Pythagoras' identity on one of the right triangles
with leg 72 ÷ 2 = 36 and hypotenuse = 39
h² + 36² = 39²
h² + 1296 = 1521 ( subtract 1296 from both sides )
h² = 225 ( take square root of both sides )
h = [tex]\sqrt{225}[/tex] = 15
Then
A = [tex]\frac{1}{2}[/tex] × 72 × 15 = 36 × 15 = 540 mi²
Maria sells painting in a art gallery. She earns $375 each week plus a commission of 2.5% of her swelled. What is the minimum amount of sales she must have this week to earn at lease $500.
Answer:
5000.00
Step-by Step
500.00-375.00 = 125.00
5000 x 2.5% = 125.00
375.00 + 125.00 = 500.00
