So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
Answer:
-2 4x square is the answer
Answer:
The answer is Y = 1/2x + 9
Step-by-step explanation:
The general equation with a slope and intercept is:
y=mx+b
We are given a slope of 1/2, which represents the "M" part of the equation.
So we have:
Y = 1/2x + b
We do not know what "b" is, so the equation is not complete.
We plug in "-2" for X and "8" for Y:
8 = 1/2 (-2) + b
b = 9
So, the full equation is: Y = 1/2x + 9
Answer:
The answer is 185
Step-by-step explanation:
25 times 7 =185
<span>Let's find out the ball's acceleration
V^2 = U^2 + 2as
Where the distance S = 6 feet and U = 45.
Suppose he just took off so V = 0 and we are left with U^2 =2as
(45)^2 = 2a(6)
a = 2025/12 = 168.75 ft/s^2
Also S = ut + 1/2 at^2
Here S = 5ft and U= 0; a = 168.75. So we have 5 = (1/2) * 168.75 * t^2
So we have 5 * 2 = 168.75 t^2
T^2 = âš 10/ 168.75 = 0.00596 = âš0.006
T = 0.0077s</span>
