Let 'c' represent the number of pictures Chelsea took.
Let 's' represent the number of pictures Sonya took.
For last year's Thanksgiving, c + s = 236
For this year's Thanksgiving, let 'x' represent the number of photos taken in total. x = c + s, where c and s are two integers that are the same (c = s).
And we know that for both years, c + s + x = 500.
As we know that c + s is already 236 from last year, we can remove c + s from the equation in bold and replace it with 236 instead.
236 + x = 500.
Now we have to isolate the x term.
x = 500 - 236
x = 264.
We know that x = c + s, where c and s are the same, so we can just use one of the variables and double it (so you either get 2c or 2s - it doesn't matter which one you pick because they're both the same).
2c = 264
c = 132
c = s
s = 132.
Both took 132 pictures this year.
Find two pefect lines that touches the middle then do rise over run and that will be your slope
Answer:
ratio= 120:8
8/8=1
120/8=15
the unit rate is 15:1
It means that one floor is 15 feet high.
The ratio of the height of the building to the number of floors is 120:8. The unit rate is 15:1. This means that each floor of the building is 15 feet high.
Answer:
154
Step-by-step explanation:
The important thing to recognize about finding the area for these types of figures is to make it into shapes that are easier to calculate, such as rectangles.
1) There are different ways of creating rectangles from this figure; however I will choose to cut the shape into two rectangles:
Imagine if the "L" was cut down from the top part of the "L" to the bottom, as to create to rectangles.
There will be a tall vertical rectangle and a small horizontal rectangle.
The tall rectangle will have a length of 17 and a width of 6
The smaller rectangle will have a length of 4 and a width of 13
2) Calculate the areas of the two rectangles and add them together:
Tall: 17 * 6 = 102
Small: 4 * 13 = 52
Total = 102 + 52 = 154
F(x) = 36.77e^(-0.72x)
log f(x) = log36.77e^(-0.72x)
log f(x) = log 36.77 + log e^(-0.72x)
log f(x) = 3.6 + (-0.72x)log e
log f(x) = 3.6 - 0.72x
0.72x = 3.6 - log f(x)
x = 5 - 1.39 log f(x)
