Kisha saved $12.00 when buying a coat. The coat was on sale for 30% off. What was the original price of the coat?
Answer:
$40
Step-by-step explanation:
As per linear equation, the original price of the coat is $40.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, Kisha got the discount of $12.00 while buying the coat.
The coat was on sale for 30% off.
Let, the original price of the coat was $x.
Therefore, the price Kisha saved while buying the coat was:
$(x ×0.3)
= $0.3x
Now, 0.3x = 12.00
⇒ x = (12.00 / 0.3)
⇒ x = 40
Therefore, the original price of Kisha's coat was $40.

Write an equation of the line that passes me that passes through (2,-5) and is parrallel to the line 2y=3x+10
Step-by-step explanation:
parallel means same slope/gradient
2y = 3x + 10
y = 1.5x + 5
let equation be y = 1.5x + b
sub (2, -5)
-5 = 1.5(2) + b
b = -8
therefore y = 1.5x - 8

When a quantity is increased or
decreased, what PERCENT describes the
original or starting value?
Answer:
100%
Step-by-step explanation:
The percentage that describes the original value we are calculating from is 100%
This represents the original value that we are working with.
For example if we are to decrease by 10%, it means we are to be left with 90%
If also we are to increase by 10%, it means that we are to be left with 110%

the volume of a large sphere (of radius R) is twice the volume of a smaller sphere (of radius r). form an equation linking r and R.
Step-by-step explanation:
radius of large sphere is R,
then volume is (4/3)*pie*R³
and
the radius of small sphere is r,
then volume is (4/3)*pie*r³
condition is,
volume of larger sphere is twice of the volume of smaller sphere.
then, (4/3)*pie*R³=2*(4/3)*pie*r³;
R³= 2r³
R=(2^⅓)*r
You are standing 500 meters from a SpaceXᵗᵐ Rocket that is preparing to take off. The angle of elevation to the top of the rocket is 8o. Find the height of the rocket. Round your answer to the nearest tenth The height of the rocket is meters
Answer:
70.3mStep-by-step explanation:
The set up will be a right angled tringle with angle of elevation of 8°.
The distance you are standing from the rocket (adjacent) = 500m
The height of the rocket (opposite) = x
Using the SOH CAH TOA trig identity;
According to TOA
tan(theta) = opp/adj
tan 8 = x/500
x = 500tan8
x = 500(0.1405)
x = 70.27
x = 70.3m (to the nearest tenth)
Hence the height of the rocket in meters is 70.3m
Johnathan went shopping at HEB. He began to look at two different cereals below Sunshine Cornflakes: 24-ounce box for $4.32 Bright Start Cornflakes: 36-ounce box for $5.76 How much less does it cost per ounce?
Answer:
Step-by-step explanation:
Given that:
Johnathan looked at two different portions of cereals at the supermarket.
They are:
Sunshine Cornflakes: 24-ounce box for $4.32
Bright Start Cornflakes: 36-ounce box for $5.76
To calculate the cost of one ounce of Sunshine cornflakes, we have:
24-ounce box for $4.32
1 - ounce box will be x
x = ($4.32 × 1 ounce box) / 24 ounce box
x = $0.18
1 - ounce box will be = $0.18
To calculate the cost of one ounce of Bright star cornflakes, we have:
36-ounce box for $5.76
1 - ounce box will be = ( $5.76 × 1 ounce box) / 36 ounce box
1 - ounce box will be = $0.16
Since 1 - ounce box of Bright star cornflakes is lesser than 1 - ounce box of Sunshine Cornflakes.
Then, Bright star cornflakes costs ($0.18 - $0.16) = $0.02 per ounce box lesser than Sunshine Cornflakes.
Thus, Bright star cornflakes will be a better buy.

Give the vertex of each function or inequality
f(x)=|x-1|-1
Answer:
(1,-1)
Step-by-step explanation:
The vertex is the minimum point (in this case). That happens when x - 1 = 0. The reason for that is because the absolute value is going to added to minus 1. The absolute value is always plus.
x - 1 = 0
x - 1+1 = 0 + 1
x = 1
So the minimum point is going to be (1,-1)

Jon has to choose which variable to solve for in order to be able to do the problem below in the most efficient manner.
6x+3y - 27
5x+2y = 21
Which variable should he choose so that he can use substitution to solve the system?
Jon should solve for y in the first equation because the coefficients can be reduced by a common factor to
eliminate the coefficient for y.
