A) Total cost of materials: 145.86 + 52.91 + 17.63 = $216.40
b) Percent cost of hardware: 17.63/216.40 = 0.081
c) Percent cost paint and hardware: (17.63 + 52.91)/216.40 = 0.326
Answer:
the thirs one
Step-by-step explanation:
<h2>sum of angle of triangle is 180°</h2>
<h2>A+B+C = 180 </h2>
<h2>38°+75°+ X = 180°</h2>
<h2>113° + X = 180°</h2>
<h2>X = 180° -113</h2>
<h2>X = 67°</h2>
Answer:
D.
Step-by-step explanation:
The mean is 11,000
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is

total distance of other way is

now, we can that distance is same from both sides
so, we get

now, we can solve for t



now, we can find one way distance

miles..............Answer
