Answer:
10% discounted
Step-by-step explanation:
500× X = 450
while X is the sale price
so we solve for X
(500X)÷500 = 450 ÷ 500
X = 0.9
then we turn that into percentage
0.9 × 100 = 90%
finding the discount percentage
100% - 90% = 10%
Answer:
Depends
Step-by-step explanation:
This question is a very advanced question, but this depends on the grape that the raisin was previously.
Answer:
Step-by-step explanation:
x^2 - 4 * x + 4 = (x - 2)^2.
Answer:
w ≤ 2200
Step-by-step explanation:
If a lift can lift a maximum weight of 2200pounds,<u> this means that the lift can not life a weight greater than 2200pounds.</u> For the expression needed, the inequality sign to use will be a less than or equal to sign( ≤ ).
Hence the requires inequality expression will be w ≤ 2200
Answer:
The price of pretzels in 1975 = $1.80
Step-by-step explanation:
To answer this question we are assuming the steady rate means linear.Let x be the year and y be the price.
We need to find the slope
m = (y2-y1)/(x2-x1)
= (4.80-4.05)/(2015-2005)
=.75/10
= .075
The slope is .075
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-4.80 = .075(x-2015)
Distribute
y - 4.80 = .075x -151.125
Add 4.80 to each side
y - 4.80+4.80 = .075x -151.125+4.80
y = .075 x - 146.325
We want to find out how much pretzels were in 1975. Put in x=1975
y = .075(1975) -146.325
y = 148.125-146.325
y=1.80
