Answer:

<h2>Original price = $ 120</h2>

Step-by-step explanation:

To find the original price given the new price and percentage discount we use the formula

original \:  \: price =  \frac{100}{(100 - x)}  \times new \:  \: price \\

where

x is the percentage discount

From the question

new price = $ 84

% discount = 30%

Substitute the values into the above formula and solve

That's

original \:  \: price  =  \frac{100}{100 - 30}  \times 84 \\  =  \frac{100}{70}  \times 84 \\  =  \frac{10}{7}  \times 84 \\  = 12 \times 10

We have the final answer as

<h3>Original price = $ 120</h3>

Hope this helps you

Need help from the same last question. (I dont need to do #10)
AysviL [449]
8. The y-intercept is -10. You can find this by just seeing where the line would hit the y-axis. This is basically the starting point so the Scuba Diver's decent started at -10m.

9. You have the y-intercept so put that in slope-intercept form. y=mx+b

y=mx - 10

Now find the slope by picking two points and using the slope formula. I'll use 
(30,-6) and (50,-4), and then plug in the values. 30 = x1, -6 = x2, 50 = x2, -4 = -4. Simplify.

m= y2-y1     -4 - (-6)       2            1
      -------- = ----------- =  --- / 2 =   --- 
      x2-x1      50 - 30      20          10

Area and explanation please
kondaur [170]
Hello!

The area of the square would be 400 cm sq, because the formula for area of a square is A = s sq

Since we already have the area of the parallelogram and we have the measurement of its base, we will be able to find its height!

The formula for the area of a parallelogram is:

A = bh

A = 16 × ____

Since we have to multiply its dimensions together to find the AREA, we will have to do the opposite to find its height.

What's the opposite of multiplication? Division! So I'm simply going to flip the multiplication problem over and turn it to a division one:

H = A ÷ b

As you can see, to find the height we must divide its area by its base.

H = 400 ÷ 16

H = 25

Therefore, the height of the parallelogram is 25 cm.

I. Write the answer with the proper label. ( 2 pts each)
Y_Kistochka [10]
S = D/t
120 = D / 0.5
D = 120*0.5
D = 60 km

S = D/t
70 = D / 2.5
D = 70*2.5
D = 175 miles
