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

What is the product of ( 8 – j10 ) and ( 6 + j4) in rectangular form?
a) 48 – j 60
b) 88 – j 28
c) 38 + j 28
d) 48 + j 60
Answer:
b
Step-by-step explanation:
Given
(8 - j10)(6 + j4) ← expand factors using FOIL
= 48 + j32 - j60 - j²40 [ j² = - 1 ]
= 48 - j28 + 40
= 88 - j28 → b

Lillian wants to give 1/3 of a pizza to each of six girls at her party. Dragon drop the correct equation an answer to find how many pizzas Lillian needs
Answer:
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]
[tex]Amount = 2[/tex]
Hence, Lilian needs 2 pizza

Thor made 45 gallons of of punch. The recipe he followed called for 7/9 of the punch to be orange juice. How many gallons of orange juice did Thor use to make the punch
============================================================
Work Shown:
x = orange juice amount
x = (7/9)*(total amount of juice)
x = (7/9)*45
x = (7/9)*(45/1)
x = (7*45)/(9*1)
x = 315/9
x = 35 gallons of orange juice
-------------------------
Another way to approach the problem:
Draw a rectangle and split it into 9 equal slips. If the whole rectangle's area is 45 square units, then each little skinny rectangle is 45/9 = 5 square units.
Shade in exactly 7 of these little rectangular slips. The shaded portion represents 7*5 = 35 square units, which corresponds to the answer of 35 gallons.

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
equation equivalent to 64
Answer:
x - 64 = 0
x - 32 = 32

if a board 8ft is cut into three equal pieces how long are they
4x - 3y =24
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

The weekly sales at two movie theaters were recorded for a random sample of 25 weeks. A 95 percent confidence interval for the difference in mean weekly sales for the two movie theaters was calculated as ($1,288,$2,586). With all else remaining constant, which of the following would have resulted in a confidence interval narrower than the calculated interval? A sample size less than 25 A sample size less than 25 A A sample size greater than 25 A sample size greater than 25 B An increase to 99 percent confidence An increase to 99 percent confidence C A sample mean greater than $1,937 A sample mean greater than $1,937 D A sample mean less than $1,937
Answer:
A sample size greater than 25
Step-by-step explanation:
Margin of error of a confidence interval:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which z is related to the confidence level(higher confidence level means higher z) [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
The higher the margin of error, the wider the interval is.
To have a narrower interval:
For a narrower interval, the margin of error has to be diminished. This can be achieved reducing the confidence level, or increasing the sample size.
In this question:
There are no options that say reducing the confidence level, so we should increase the sample size, that is, a sample size greater than 25.

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
