Well i think it is true,because when you Multiplying you will not have a one decimal place
To find the area of the triangle, you will need to know the length of the base and there length of the height.
You can find both of these by using the circles that are given.
If the total length of the circles is 35 cm, then each circle has a length of 7 cm. If these are circles, then each circle has a height of 7 cm also.
A = 1/2 x b x h
1/2 x (4x7) x (2x7)
A = 196 square cm
18=r/2
Multiply by 2 on each side,
36=r
r=36
Hope this helps.
Answer:
y = 2.54
Step-by-step explanation:
Please input an actual table, such as the following:
x y
5 12.7
6 15.24
7 17.78
8 20.32
It appears that we're converting inches to centimeters.
It so happens that 1 inch = 2.54 cm. The '2.54' is the slope of a straight line, as the number of cm equivalent to x inches is c = 2.54x.
Arbitrarily taking the 2 points (5, 12.7) and (8, 20.32), we find the slope of the line through these points. As we go from the first to the second, the x-value ('run') increases from 5 to 8 (that is, it increases by 3) and the y-value ('rise') increases from 12.7 to 20.32 (that is, it increases by 7.62. Thus, the slope of the line through these two points is m = rise / run = 7.62 / 3 = 2.54.
Now find the equation of the line thru these two points. Using the slope-intercept formula y = mx + b and the points (5, 12.7) we get this equation for the y-intercept (b):
12.7 = 2.54(5) + b
which tells us that b = 0.
Therefore, the desired relationship is y = 2.54 and this is a proportional relationship (no y-offset).
