Answer:
57.60
Step-by-step explanation:
If the coat is marked up 28%, then the cost is increased by 28% to produce the selling price.
SP = 45 + 28/100 * 45
SP = Selling Price
SP = 45 + 28*45 / 100
SP = 45 + 1260 / 100
SP = 45 + 12.60
SP = 57.60
Answer: The selling price is 57.60
Answer: x = 25, y=15, z = 58
Step-by-step explanation:
Answer:
y=-2x-5
Step-by-step explanation:
slope (m)= -2, point (-4,3) put in y=mx+B
3 (y)= -2 [m](-4) + B
3=-2 (-4)+B. - multiple -2 and -4
3= 8 +B. - two negatives. multipled gives you a positive
3=8+B. - subtract 8
-8 -8
-5=b
y= -2x-5
Answer:
3. B

An isometric transformation is where the size and shape of the object stays the same in the transformation. Reflection, rotation and translation are all isometric transformations. . Dilation is not.
Answer is B.
Answer: length of rectangular parking lot = 24 yards
Width of rectangular parking lot = 20 yards.
Step-by-step explanation:
Let L represent the length of the rectangular parking lot.
Let W represent the width of the rectangular parking lot.
The rectangular parking lot has a length that is 4 yards greater than the width. It means that
W = L - 4
The formula for determining the area of a rectangle is expressed as
Area = LW
The area of the parking lot is 480 square yards.. It means that
LW = 480- - - - - - - - - - 1
Substituting W = L - 4 into equation 1, it becomes
L(L - 4) = 480
L² - 4L = 480
L² - 4L - 480 = 0
L² + 20L - 24L - 480 = 0
L(L + 20) - 24(L + 20) = 0
L - 24 = 0 or L + 20 = 0
L = 24 or L = - 20
Since the length cannot be negative, then L = 24
W = L - 4 = 24 - 4
W = 20
