The Book store is having a sale. All hardback books are 20% off, and all paperbacks are 10% off. Suppose you buy four paperbacks that originally cost $9 each and two hardbacks that originally cost $20. What will be your final cost if you pay an 8.50% tax?
Answer:
$22.03
Step-by-step explanation:
20 + 9 = 29
20 + 10 = 30
29 - 30% = 20.3
20.3 + 8.50% = 22.03
Answer: $ 22.03
hope this helps

A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function f(x)=-5x2+6x+100 (graphed below) represents this situation where x is time and y is the distance off of the ground.
e. What would the new function be? What kind of transformation is this?
f. Would you still use the same domain and range? Why or why not?
Answer:
a) The domain of the function is . , , b)The range of the function is . , , c) The ball is 73 meters off of the ground at x = 3 seconds.Step-by-step explanation:The complete statement is: A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function represents this situation where x is time and y is the distance off of the ground. a) What domain does the function make sense? b) What range does the function make sense ? c) How far off the ground is the ball at time x = 3 seconds?a) Let and be the time, measured in seconds, and the distance of the ground, measured in meters, respectively. Time is a positive variable, so domain corresponds to the interval when and . That is: Therefore, the domain of the function is . , b) The distance off of the ground is also a positive variable, where ball is thrown upward at a height of 100 meters and hits the ground at a height of 0 meters. Hence, the range of the function is . , c) The distance of the ball off of the ground at x = 3 seconds is found by evaluating the function:The ball is 73 meters off of the ground at x = 3 seconds.

Jordan works at a bakery. The owner tells Jordan she wants to take 20% off a $75.00 cake. If the cake still doesn't sell, the owner will again reduce the price by 10%. Jordan tells the owner to reduce the original price by 30% because the sale price would be the same.
Is Jordan correct?
Yes, the owner's method and Jordan's method both equal a 30% discount off the original price.
Yes, the sale price for both the owner's method and Jordan's method is $52.50.
No, Jordan's method has a greater effect on the sale price.
No, the owner's method has a greater effect on the sale price

Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120
Solve a = d+c/d for d.

Write each equation in slope-intercept form of the equation of a line. Underline the slope and circle the y-intercept in each equation.
x+3y=0
The slope-intercept form is _____
The slope is _____
The y − intercept is ( ______
,
).
Answer:
Slope-intercept is y=-x/3
The slope is -1/3
The y-intercept is 0
Step-by-step explanation:
First, we need to put this as slope-intercept for which is y=mx+b
3y=-x
y=-x/3
hope this helps!
Answer:
The slope-intercept form is y= -(1/3)x
The slope is - (1/3)
The y − intercept is 0
,
Step-by-step explanation:
x+3y=0
Substract x on both sides
3y= - x
Divide by 3 on both sides
y= - (x/3)x
y= -(1/3)x
