The length of a car’s skid mark in feet is given by L = 0.046s

Alexxandr [17]

100 = 0.046s^2 - 0.199s + 0.264
0 = 0.046s^2 - 0.199s - 99.736
s= 48.77691127... or -44.45082431 (reject)

The car's speed was approximately 48.8 mph.

A sells to b an item at 15% profit. B sells the same item to c at 20% profit. If c pays $1656 for it. What is the price at which

andrew11 [14]

Answer:

The price at which A bought the item is $1200.

Step-by-step explanation:

Suppose, the price at which A bought the item is $x$ dollar.

A sells the item to B at 15% profit. That means, the selling price to B $= x+(0.15*x)=1.15x$ dollar.

B sells the same item to C at 20% profit. That means, the selling price to C $= 1.15x+(1.15x*0.20)=1.38x$ dollar.

Given that, C pays $1656 for the item. So, the equation will be.......

$1.38x=1656\\ \\ x=\frac{1656}{1.38}=1200$

So, the price at which A bought the item is $1200.

Find the area of this picture

bezimeni [28]

Answer:

30.3

Step-by-step explanation:

First we find the area of the trapezoid. The formula for that is (b1+b2)/2(h)

2+10=12

12/2=6

6x4=24

To find the area of a semicircle we do πr²/2

2^2=4

4x3.14=12.56

12.56/2=6.28

24+6.28=30.28

That is extremely close to 30.3 so the paper must be a bit off.
