Answer:
8) complementary, 45°
9) supplementary, 5x = 135°, (x+18) = 45°
10) alternate angles, 49°
Step-by-step explanation:
For 8th question
35 + 5x = 90° because the given angles are complementary
5x = 90 - 35
5x = 45
x = 9
For 9th question
5x + x + 18 = 180° because the given angles are supplementary
6x = 180 - 18
6x = 162
x = 27
For 10th question
3x + 1 = 49° because these angles are alternate
3x = 49 - 1
3x = 48
x = 16
A is the answer because rolling a number cube doesn't effect the outcome on flipping coin
Independent event mean probability of one outcome occurance is not affected by the probability of another event occuring.
Answer:
The inequality that will be used would be
x + 22 <= 55
Answer:
29%
Step-by-step explanation:
To find the decrease from 50 to 21 you would subtract 50 - 21. You get 29. This is the same as 29/100. 29/100 is also 0.29 or 29%.
Hope it helps! (I'm so sorry if it's incorrect).
Answer:
Step-by-step explanation:
radius of a coin is 12 mm
Diameter of the coin is twice the radius = 2 x 12mm = 24mm
The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m
Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²
what is the area of the coin
