Answer:
Step-by-step explanation:
3x + 4 + 8x + 4 = 140 degree (sum of two interior opposite angle is equal to the exterior angle formed)
11x + 8 = 140
x = 140 - 8
x = 132 /11
x = 12
angle S = 3x + 4
=3*12 + 4
=36 + 4
=40 degree
89 + 5x - 7 = 14x + 1
82 + 5x = 14x + 1
82 - 1 = 14x - 5x
81 = 9x
81/9 = x
9 = x
angle H = 5x - 7
=5*9 - 7
=45 - 7
=38 degree
Answer:
5 hours
Step-by-step explanation:
Electrician got 90 for the first hour from the total bill, thus we can say:
330 - 90 = 240 remaining for remaining hours
$60 per hour, so $240 for how many hours?? We divide:
240/60 = 4 hours
So, electrician works 4 hours for 60 per hour = 2 * 6 = 240
and 1 hour for 90 (first hour) = 1 * 90 = 90
Total Bill is 240 + 90 = 330 {exactly what we have}
So we have checked and back-worked our problem to get electrician's total hours of work:
1 + 4 = 5 hours
Answer:
b. gravity acting on the edges of plates and friction between the plate and the asthenosphere.
Answer: 1/5 or 20%
Step by Step Explanation:
Since there is 10 possible out comes, and you favor 2 of them, roling the die once will give you a 10/2 or 1/5 chance of getting 3 or 5.
Formula: Number of outcomes divided by Favorable Outcomes
