Find the nearest numbers that are greater and less that your number, in this case, 7 and 8 which square to 49 and 64 and average them by adding them together and dividing by two.
7+8=15
15/2=7.5
7.5 is the nearest estimated square root of 50 that I can get, but the real answer is about 7.071067811865475. (I used a calculator)
Answer:
A' (3,1)
Step-by-step explanation:
You start with (-3,5)
Translation Down 4: (-3,1), just subtract 4 from the y-coordinate
Reflection over the y-axis: (3,1), multiply -1 to the x-coordinate
Answer:
The number rounded to the nearest tenth is 15.1
Step-by-step explanation:
<u>Step 1: Make an equation</u>
When a number is decreased by 27%, the result is 11.
x * (1 - 0.27) = 11
<u>Step 2: Solve inside the parenthesis</u>
x * (1 - 0.27) = 11
x * 0.73 = 11
<u>Step 3: Divide both sides by 0.73</u>
0.73x / 0.73 = 11 / 0.73
x = 15.1
Answer: The number rounded to the nearest tenth is 15.1
Answer:
y = 1x + 2
Step-by-step explanation:
To fill in slope intercept form(y = mx + b) identify the initial value(b) and slope(m).
The initial value is the y coordinate when the x coordinate is 0. It is also known as the point where the line crosses the y axis. This point on the graph is (0, 2). So, the initial value is 2.
Slope is identified by finding a point on the graph that the line passes through and creating a right triangle to a point that is even with both point. Then, divide the y coordinate of that point by its x coordinate. One coordinate you could use is point (-2, 2). 2 divided by -2 is -1. But, since the line has a positive association, the slope is going to be a positive number. So, the slope is 1.
Now fill in the the slope intercept form.
y = mx + b ---> y = 1x + 2
Okay so you have to do
138 times .40-move the decimal over 2 times
that is 55.2 so 40 percent of 138 is 55.2 so add that on to 138 to get 192 students at the school. There you go :)
