Answer:
60
Step-by-step explanation:
m(ADB) + m(BDC) = 90°
(3x+9) + (2x -4) = 90°
5x + 5 = 90°
5x = 85
5x/5 = 85/5
x = 17
m(ADB) = 3x + 9
3.17 + 9 = 51 + 9 = 60
Hope this helps ^-^
Answer:
4π
Step-by-step explanation:
-A circle subtends a total angle of 360 ° from its center.
-The length of an arc is directly proportional to the angle it subtends from the circle's center.
#The arc's length can therefore be calculated as:
Hence, the length of the arc is 4π
The probability of getting any one number would be 1/6
There are 2 numbers that are lower than 3, so the probability would be 1/6 + 1/6 = 2/6, which simplifies to 1/3.
Answer:
D
Step-by-step explanation:
Fractions are much easier to compare when they share a single denominator. Multiplying the numerator and denominator both of 3/8 by 8, we get 24/64. Then the distance between 3/8, or 24/64, and 61/64 is:
N = 61/64 - 24/64
Answer D is correct. 3/8 + N = 61/64 is equivalent to the above result.
