A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answer:
a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.
b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:
315/x = 70/100
This is because 315 is part of the whole and is 70% of the value of x.
Step-by-step explanation:
Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Answer:
a. $450
b. $135
c. 70%
Step-by-step:
[tex]\frac{70}{100} = \frac{315}{450}[/tex] since these two fractions are equal to each other that means the orginal price is $450.
(sale price/original price)x100= % of original price
(315/450)x100=0.7=70%

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3

Answer:
C
Step-by-step explanation:
Answer:
c)
Step-by-step explanation:
so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180
with that, let us get to solving these equations to see which one is less than 180-
a) 85/10*180=1530>180
b) 850/100*180=1530>180
c)0.85*180=153
'c' is the only answer choice less than 180>153
another way to solve this would be to focus solely
on answer choice 'c'-
so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-
0.85*180=153>180
good luck :)

(-2,3) is one vertex of a square on a coordinate plane. Name three points that could be the other vertices.
Answer:
(0,7) and (-4,7)
(-2,3) is vertex
Equation is (X+2)2+3
When x = 0, y = 7 and when x = -4, y = 7
(-2,3) is one vertex of a square on a coordinate plane. (0,7) and (-4,7) could be the other vertices.
How can we perceive the cartesian coordinate plane?The cartesian coordinate plane is an infinite 2-dimensional plane. Any 2-dimensional figure can be drawn on an infinite 2d plane.
Each point of a cartesian plane is tracked by a location.
It is the perpendicular distance of that point from the horizontal axis and vertical axis usually named the x-axis and y-axis.
The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called the x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis and called the y-coordinate of that point.
(-2,3) is one vertex of a square on a coordinate plane.
The equation is [tex](X+2)^2+3[/tex]
When x = 0,
[tex](0+2)^2+3\\\\4+3[/tex]
y = 7
when x = -4,
[tex](-4+2)^2+3\\\\4+3[/tex]
y = 7

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100
Answer:
yes
Step-by-step explanation:
to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-
81*2/9=18
900*2/9=200
72*2/9=16
72*2/9=16
450*2/9=100
now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true
