c) The phone case you want to buy is marked down 30%, and you have a 25% off coupon.
You pay $42.00. Can this equation be used to find the original price of the phone case? If so,
what is the original price of the item? Explain. (5 points)
(0.7c) = 42
Answer:
Step-by-step explanation:
Remark
The problem with this question is that you don't exactly know what the 25% does.
I think the way to do the problem is to consider where the 42 dollars comes from.
I think the beginning part of the problem is to develop an equation which you may not be able to solve.
So the cost using the 30% reduction is 0.7c where c is the original cost. But the 25% makes the actual cost for the person = 0.7c - 25% of 0.7c
The result is 42 dollars.
0.7c - 0.25*0.7c = 42
If I'm right, that can be solved.
0.7c - 0.175c = 42
0.525c = 42
c = 42/0.525
c = 80 dollars.
So before all the reductions and everything else, the case actually cost 80 dollars.

What is the product of 5/10 x 4/5 in lower terms (simplified)?*
A.20/5
B.2/5
C.9/15
D.10/25
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
We have two fractions being multiplied and are being asked to simplify it.
When you multiply two fractions, you always multiply across :
[tex]\frac{5}{10}*\frac{4}{5} = \frac{5*4}{10*5}[/tex]
[tex]\frac{20}{50}[/tex]
Since both the numerator and denominator end in 0, we can simplify this by cutting out the zeroes.
Leaving us with B. 2/5

Find the x and y intercept then use them to graph the line
Answer:
y=21-7x
-7 is your slope
21 is your y-intercept
Step-by-step explanation:
you send the 4x the other side and you send the other side opposite so it going to be -4x
-3y= 24-4x
than you divide -3 on 24 and -4x
1. A Square shaped wooden plate has a diagonal length of 30cm. Can you find the Perimeter of plate ?
Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm

10. If possible, determine whether or not triangles LQP and LMN
are similar. Give a detailed explanation for your answer.
PLEASE HELP!!
Answer:
They are similar
Step-by-step explanation:
If two triangles are similar, the ratio of their corresponding side lengths must be equal to each other.
This means that for ∆LQP and ∆LMN to be considered similar to each other, therefore:
LM/LQ = LN/LP
LM = 100
LQ = 12
LN = 75
LP = 9
LM/LQ = 100/12 = 25/3
LN/LP = 75/9 = 25/3
LM/LQ = LN/LP = 25/3, therefore ∆LQP and ∆LMN are similar to each other because the ratio of their corresponding side lengths are the same.
How can I solve
2y=4-3y
Add 3y to both sides then divide both sides by 5.
[tex]2y=4-3y\implies 5y=4\implies y=\frac{4}{5}[/tex]
Hope this helps.
Answer:
y = 0.8
Step-by-step explanation:
You must rewrite the equation so that the y variables are all on one side of the =, and the numbers are on the other. To do this, you must add 3y to 2y (because it is originally -3y, and you have to do the opposite, meaning you add rather than subtract):
5y = 4
Next, to remove 5 from the equation, since 5y means they are multiplied together, you must do the opposite, so divide each side by 5:
5y ÷ 5 = y
4 ÷ 5 = 0.8
Therefore, y = 0.8
Sebuah wadah berbentuk kerucut dengan volume 16.632 cm3 dan tinggi 36 cm. Tentukan jari jari alas kerucut tersebut
Answer:
21 cm
Step-by-step explanation:
The computation of the radius is shown below:
As we know that
The volume of the cone = [tex]\frac{1}{3} \pi r^2h[/tex]
where
Volume of the cone is 16.632 cm^3
height = 36 cm
So, the radius of the cone is
[tex]16.632 cm^3 = \frac{1}{3} \times \frac{22}{7} \times r^2 \times 36\\\\16.632 cm^3 = \frac{22}{7} \times 12 \times r^2\\\\16.632 cm^3 = \frac{264}{7} \times r^2\\\\r = \sqrt{441} \\\\r = 21 cm[/tex]

2 pizza
Step-by-step explanation:
Given
[tex]Pizza = \frac{1}{3}[/tex]
[tex]Girls = 6[/tex]
Required
Amount of Pizza needed
To do this, we simply multiply the fraction of pizza by the number of girls i.e.
[tex]Amount = Pizza * Girls[/tex]
[tex]Amount = \frac{1}{3} * 6[/tex]
