The wholesale price for a chair is $124. A certain furniture store marks up the wholesale price by 16%. Find the price of the chair in the furniture store.
Round your answer to the nearest cent, as necessary.

Answers

Answer:

$143.84

Step-by-step explanation:

Given the following question:
Initial price of the chair was $124....
Marked up 16% (which means the price has increased by 16%)
Find the new price of the chair...

In order to find the answer, we find 16% of a given number in till it equals 124 which was the initial price.


[tex]\frac{143.84-124}{124} \times100=143.84-124=19.84\div124=0.16\times100=16[/tex]
16% of 143.84 is 124
143.84 is already rounded to the nearest cent

Which means the new price of the chair is "$143.84"

Javier walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Javier first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.

How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.

How many minutes before Javier arrived was the water tank completely full? Explain or show your reasoning.

Answers

Answer:1)  Gallons per minute change is -2/3 gallons per minute  since it decreases by 2 gallons in 3 minutes

2)  we have 5 gallons and lose 2/3 gallons per minute

(2/3 gal/minute)(x minutes) = 5 gallons

x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3)  There were 10 gallons when the tank is full

    That is 3 gallons more than the 7 gals there when Jada arrived.

    (2/3)(x) = 3

    x = 3(3/2) = 9/2 = 4 1/2 minutes

The tank was full 4 1/2 minutes before Jada arrived.

Explanation:

a) burritos are the independent variable because it is labeled as x. X will always be the independent variable. The reason I am confused is because all throughout my learning I was told "time" will always be independent and it had always proved to be true. I would just go with burritos though.

b) linear function is y=0.75x, with 0.75 being the slope representing the amount of time taken to make x amount of burritos. I see you already did most of the work! You just have to remember that to find slope (or m), that you do change in y/change in x.

c) when graphing, draw a point at the origin, (0,0). Then count 0.75 units up, and move 1 unit to the right. Your line should be from left to right going "upward".

d) your answer for d is correct

can some help i cant figure this out

Answers

Answer:

240cm²

Step-by-step explanation:

area of a triangle:

½ x b x h

= ½ x 6 x 4

= 3 x 4

= 12.

since there are 8 of the same triangles, they will all have the same area. so to work out the total area of a triangles, we times the area of one triangle by the 8 triangles in the polygon.

12 x 8 = 96.

for the square in the middle:

area of a square = length x width

area of a square = 12 x 12 = 144.

all we need to do is add these two totals together.

144 + 96 =240cm².

we use the units cm², because we have been multiplying xcm x ycm which can be simplified to cm² :)

240cm^2 is the answer

Solve each inequality. Graph the solution on a on a number line.
p-7/12>3/10

Answers

Answer:

so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.

p-7/12>3/10

add 7/12 to both sides

p>7/12+3/10

p>35/60+18/60

p>53/60

so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right

Which statement is TRUE?

A. Trapezoid W'X'Y'Z' is smaller than Trapezoid WXYZ because the scale factor is less than one.

B. Trapezoid W'X'Y'Z' is smaller than Trapezoid WXYZ because the scale factor is greater than one.

C. Trapezoid W'X'Y'Z' is larger than Trapezoid WXYZ because the scale factor is less than one.

D. Trapezoid W'X'Y'Z' is larger than Trapezoid WXYZ because the scale factor is greater than one.

Answers

Answer:

D

Step-by-step explanation:

in the question the scale factor is 4 so that means it is a dilation (getting larger) because the scale factor is >1

Yes the answer is D because if it is over 1 on a scale factor then it’s larger and it’s dilated which means bigger
