Answer: I think it's 35%

With original price $160 and 35% discount,

Price after discount: $104.00

You saved: $56.00

The term discount can be used to refer to many forms of reduction in the price of a good or service. The two most common types of discounts are discounts in which you get a percent off, or a fixed amount off.

A percent off of a price typically refers to getting some percent, say 10%, off of the original price of the product or service. For example, if a good costs $45, with a 10% discount, the final price would be calculated by subtracting 10% of $45, from $45, or equivalently, calculating 90% of $45:

10% of $45 = 0.10 × 45 = $4.50

$45 – $4.50 = $40.50

or

90% of $45 = 0.90 × 45 = $40.50

In this example, you are saving 10%, or $4.50.

Step-by-step explanation:

A circle has a center of (5,-5) and goes through (6,-2). What is the radius?
Fittoniya [83]
Start with the equation of a circle whose center is at (h,k) and whose radius is r:

(x-h)^2 + (y-k)^2 = r^2

Substituting the given coordinates of the center:

(x-5)^2 + (y-[-5])^2 = r^2, or (x-5)^2 + (y+5)^2 = r^2

Substituding the given coordinates of a point (6,-2) on the circle:

(6-5)^2 + (-2+5)^2 = r^2

Simplifying:

1^2 + 3^2 = r^2, or 1 + 9 = r^2, or 10= r^2.  Then r = sqrt(10).

Not sure about this one help please
lutik1710 [3]

Answer:

a) -1

Step-by-step explanation:

Slope is also known as the gradient

1. assign a value to x and solve for y:

when x = 2, y = 2

when x = 4, y = 0

2. Next, use the equation of a straight line to find the gradient

y = mx + c

y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x

so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4

2m = -2 (take 4 away from 2)

<u>m = -1 </u>

What is the answer to the problem: Solve<br> (The square root of 2x-7) = 7?
quester [9]
The equation is 
\sqrt{2x-7}=7\\\text{Elevating to 2 the two sides of the equation we get:}\\2x-7=49\\\text{Therefore:}\\2x=49+7=56\\x=\frac{56}{2}=28\\\text{Solution : }x=28
