Answer:
i think its the second one because if you multiply a number by a decimal with a value lower than 1, then the number will go down, but im not positive
Step-by-step explanation:
Answer:
11 inches by 11 inches
Step-by-step explanation:
The dimensions of the original photo were 11 inches by 11 inches.
We are informed that the area of the reduced photo is 64 square inches and that In the equation (x – 3)^2 = 64, x represents the side measure of the original photo.
In order to solve for x, we shall first take square roots on both sides of the equation;
The square root of (x – 3)^2 is simply (x - 3).
The square root of 64 is ±8 but we ignore -8 since the dimensions of any figure must be positive.
Therefore, we have the following equation;
x - 3 = 8
x = 8 + 3
x = 11
One centimenter is 0.01 meters. So, you can write the measures as

Once this rewriting is done, getting the total length
is quite trivial, since all measurements are in the same unit, and we can simply sum everything:

Answer:
5 months is the answer. 21% of 2000 is 420 and 420x5=2100 which added up is $4,100 dollars and that is just over double the original amount.
Answer: 
Step-by-step explanation:
<h3>
The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
-
represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:

2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into
and then solve for "b" in order to find its value:

Therefore, you can determine that the function
is:
