Appliances at Discount City Store are on sale for 55% off of the original price. If the original price of a washing machine is $500, what does it cost after being reduced by 55% (before tax)?
Answer:
it will cost $255.
Step-by-step explanation:
225.
a product that normally costs $500 with a 55 percent discount will cost you $225.00, and you saved $275.00. You can also calculate how much you save by simply moving the period in 55.00 percent two spaces to the left, and then multiply the result by $500 as follows: $500 x . 55 = $275.00 savings.
Identify the graphed linear equation.
A) y = 5x + 2 y = 5x + 2
B) y = 5x - 2 y = 5x - 2
C) y = -5x + 2 y = -5x + 2
D) y = -5x - 2 y = -5x - 2
Answer:
Option (D)
Step-by-step explanation:
Let the equation of the given line is,
y = mx + b
m = slope of the line
b = y-intercept
From the graph attached,
Slope 'm' = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
m = [tex]\frac{-5}{1}[/tex] = -5
y-intercept of the given line = -2
Therefore, equation will be,
y = -5x - 2
Option (D) is the correct option.

Answer:
the slope is 2
Step-by-step explanation:
subtract 8x from both sides to get -4y = -8x + 24
then divide by -4 to get:
y = 2x - 6
plleaasseee hurrry need help now
Answer:
107º
Step-by-step explanation:
Okay, if 135 is adjacent to an ungiven side, then to find that, you subtract 135 from 180.
180 - 135 = 45
So the other side is 45. Now we find the last unknown given side, and since we know 180 degrees is the sum of the degrees in a triangle, we do:
28 + 45 + x = 180
73 + x = 180
Subtract 73 on both sides you get,
x = 107.
Measure DEF is 107.
Recent test scores on the Law School Admission Test (LSAT) are normally distributed with a mean of 162.4 and a standard deviation of 15.9. What is the probability that the mean of 8 randomly selected scores is less than 161?
Answer:
0.40166
Step-by-step explanation:
When given random number of samples, we solve using the z score formula:
z = (x-μ)/σ/√n where
x is the raw score= 161
μ is the population mean = 162.4
σ is the population standard deviation = 15.9
n is random number of samples = 8
Hence,
z = 161 - 162.4/15.9/√8
z = -0.24904
Probability value from Z-Table:
P(x<161) = 0.40166
The probability that the mean of 8 randomly selected scores is less than 161 is 0.40166

Find a quadratic function that includes the set of values below.
(0,4), (2,10), (4,0)
The equation of the parabola is y=
Answer:
Step-by-step explanation:
The standard form is (x - h)2 = 4p (y - k), where the focus is (h, k + p) and the directrix is y = k - p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y - k)2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p.

The scale on a map indicates that 1 inch corresponds to an actual distance of 115 miles . Two cities are 7.5 inches apart on the map . What is the actual distance between the two cities?
Can someone please help me with this question I don’t understand it. Thank you
Answer:
it is 862.5
Step-by-step explanation:
each inch is 115 miles, so if theres two inches theres double the amount that there would be if there was 1 inch, so if theres 7 inches then you would have 7 times the amount it would be if there was 1 inch, in this situation theres 7.5 so you would multiply the 115 miles by 7.5 becuase that's how many inches there is, so multiplying that is the same as adding 115 plus 115 plus 115, and so on till you get the amount you need. did this help?
What is the measure of
Answer:
m∠B = 105°
Step-by-step explanation:
Given
A = x+5B = 3xC = xWe know that the sum of angles in a triangle = 180°
A + B + C = 180°
x + 5 + 3x + x = 180°
5x + 5 = 180°
5x = 180° - 5
5x = 175
x = 175 / 5
x = 35
Thus, the measure of ∠B will be:
m∠B = 3x
= 3(35)
= 105°
m∠B = 105°

The diagram represents a triangle that is reduced by a scale factor of 0.4.
A rectangle has a base of 6 inches and a height of 2 inches.
What is the height of the original triangle?
0.8 inches
2.4 inches
5 inches
8 inches
Answer:the answer would be 8.
Step-by-step explanation:
If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.
Answer:
8

Petra bought some art supplies from an online retailer. The retailer charges a $5.95 shipping fee or 7.5% of the total purchase, whichever is
greater. If Petra's total purchase is $75,99, how much shipping will she pay?
Answer:
$81.94
Step-by-step explanation
I would subtract 5.95 to 75.99 first and get a total of 70.04 and put it off to the side then I would find out what 7.5 of the total purchase is (75.99) and that is 5.70 rounded and in the paragraph it said "whatever one is bigger" and in this case the 5.95 is bigger so you would add that to your total and get $81.94
