Answer: y - 0.18y
Step-by-step explanation:
From the question, Emerson practice a game that was on sale for 18% off the sales tax in his country.
Let y represent the original price of the game. The be used to determine the final cost of the game will be:
We have to subtract the 18% discount from the original price to get the final cost of the game. This will be:
= y - (18% of y)
= y - (18/100 × y)
= y - (0.18 × y)
= y - 0.18y
The final expression is y-0.18y
Answer:
12 centimeters
Step-by-step explanation:
The triangle is half of an equilateral one. So the hypotenuse is double the minor leg
12 centimetres
Answer:
2550yards
Step-by-step explanation:
Perimeter of a rectangle = 2L + 2W
L is the length
W is the width
If perimeter of a rectangle is 425 yards, then;
425 = 2L + 2W
425 = 2(L+W)
L+W = 425/2 .... 1
If the length and width of the rectangle are each multiplied by 6
P = 6(2L) + 2(2W)
P = 12L + 12W
P = 12(L+W) .... 2
Substitute 1 into 2
P = 12(425/2)
P = 6*425
P = 2550yd
Hence the perimeter of new triangle is 2550yards
Answer: C) For every original price, there is exactly one sale price.
For any function, we always have any input go to exactly one output. The original price is the input while the output is the sale price. If we had an original price of say $100, and two sale prices of $90 and $80, then the question would be "which is the true sale price?" and it would be ambiguous. This is one example of how useful it is to have one output for any input. The input in question must be in the domain.
As the table shows, we do not have any repeated original prices leading to different sale prices.
