The advantage of using exponential notation is that you won't have to keep writing a long number
For example, 40,000,000,000,000 would be tedious to write over again, but using exponential notation that number would be just 4 X 10^13.
If my above assumption is correct, we can easily find the area of the left side of the rectangle by finding the area of 3 things. The first is the area of the entire region.
At = (0.8)(1.0+1.4) = 1.92
Next we need the area of the circle. Which is pi*r^2, with r being height divided by two. (0.4)
C = 0.502
Finally we need to find the area of the rectangle left region. Which is basically the rectangle from the center of the circle region to the end of the left of the entire region. This is just (1.0)(0.8) = 0.8
Finally we can find the area of the light blue area by just subtracting half the area of the circle (dark blue) from the area we just calculated.
0.8 - (0.502 / 2) = 0.549
Now for the probability we do this area divided by total area.
0.549/1.92 = 0.285 or about 0.29 which is just 29%
I believe it’s 245 I believe I did this before I don’t know
Answer:
x = 32°
Step-by-step explanation:
∆KLM is an isosceles triangle because it has two equal sides, KL & KM. Therefore, the angles opposite to each of the two equal sides, which are referred to as the base angles are congruent to each other.
m<KML = m<KLM = 58°
m<MKL = 180 - (58 + 58) (Sum of triangle)
m<MKL = 64°
m<JKM = 180 - m<MKL (linear pair theorem)
m<JKM = 180 - 64 (Substitution)
m<JKM = 116°
∆JKM is also an isosceles triangle with two equal sides. Therefore, it's based angles (x & <J) would also be equal to each other.
Thus:
x = ½(180 - m<JKM)
x = ½(180 - 116) (Substitution)
x = 32°
