Answer:
80%
Step-by-step explanation:
40/50 = 80/100 = 80%
Answer:
2.56
Step-by-step explanation:
8* 32=256
256/100=2.56
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3
Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)
equation:
y = mx + c
y = 4/3 x + c
at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1
y = 4/3 x - 1 or 3y = 4x - 3
Answer:
Company B's offer is more cost effective
Step-by-step explanation:
Expected no. of repairs:
(0)(0.25) + (1)(0.32) + (2)(0.29) + (3)(0.14)
= 1.32
Cost A: 12.99 × 12 = $155.88
Cost B: 1.32 × 75 = $99
As the sum of two complementary angles = a + b = 90
degree -------(1)
Difference of two complementary angles = a – b
According to question;
The difference of two complementary angles exceed the
sume (90) by 86.
So
a – b = 90 – 86 = 4 -------(2)
adding equation (1) and (2);
2a = 90 + 4 = 94
a = 94 / 2 = 47
putting a = 47 in equation (1);
47 + b = 90
b = 90 – 47 = 43
<span>
So angle a = 47 and
angle b = 43</span>
