Answer:
1. 2.11 X10^8
2. B. 1.95 X 10^-2
Step-by-step explanation: Problem 1
is equal to 211000000 which has 8 numbers after 2. So the 10 would be to the 8th power for 2.11.
Problem 2 is equal to 0.0195.
To get it to 1.95 you’re only moving the decimal 2 places, so it’s 10 X -2.
Answer:
![\frac{7}{11}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B11%7D)
Step-by-step explanation:
We require 2 equations with the repeating digits (63) placed after the decimal point.
let x = 0.636363..... (1) multiply both sides by 100
100x = 63.6363... (2)
Subtract (1) from (2) thus eliminating the repeating digits
99x = 63 ( divide both sides by 99 )
x =
=
← in simplest form
$57-$7.50= $49.50 to spend on rides
49.50/4.50= 11
So she can go on 11 rides
Answer:
48
:)
Step-by-step explanation:
63-15 = 48
48+15= 63
Formula for the Slope: (y2 - y1) / (x2 - x1)
You can use any two points to find the slope, as long as those two points are on the line.
Point 1 = (-2, 8)
Point 2 = (0, 0)
Slope = (0 - 8) / (0 - - 2)
Slope = -8 / 2
Slope = -4
Hope this helps!
