So 70 miles per hour is 70 mile/1hour
1 mile=5280 feet
70 tmes 5280=feet=36,960
so 36,960 feet per hour
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
30000÷365=82.1917808219÷24=3.42465753425 which is about $3.42 and hour.
<span>An example of a problem that has two parts, but that can be solved by finding the whole, might be the following:
Problem 1)
2/4+2/4=1 (whole number)
Problem 2)
2/3+1/3=1 (whole number)
