Answer:
93
Step-by-step explanation:
if m = 0
11m2 would equal 0
0 - 18m
18m would = 0
so 0 + 93 = 93
Answer: The required probability is 0.25.
Step-by-step explanation:
Since we have given that
Radius of the dartboard = 4 in
Area of the dartboard is given by
Radius of the shaded region = 2 in
Area of shaded region is given by
So, the probability that the dart lands in the shaded circular region is given by
Hence, the required probability is 0.25.
Since the length of this rectangle is 13 units and the width is 5 units, the area can be found this way:
A=l*w
A=13*5
A=65 so the third choice
Hope this helps!
Answer: 139°
Reasoning:
Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.
14x-1=9x+14
To isolate the x to one side, subtract the 9x from the 14x.
5x-1=14
Now to get the constants on one side, add the 1 to the 14.
5x=15
Now divide both sides by 5 to isolate the x.
5x/5=15/5
x=3
Now that we know that, we can figure out angle 3.
9(3)+14
27+14= 41
Angle 3 = 41°
Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.
180°- 41°= 139°
<h3>Double checking your answer:</h3>
41°+139°=180°
