Answer:
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the distance in miles
y ----> the time in hours
we have
The distance is equal to subtract 35 miles from 230 miles
The time is equal to subtract 1:30 pm from 4:30 pm
substitute in the formula of speed
<em>Isolate 3 hours</em>
<em>Isolate 195 miles</em>
-20 + y = 2
y = 22
20 + 3y = 6
y = 14/3
Now,
b + 40° = 90° ( right angle )
or, b = 90° - 40°
◆ b = 50°
B) 50°
This is Right answer...
I hope it's help you...

Answer:
8/5 or 1 3/5
Step-by-step explanation:
2 2/5 = 12/5
1 1/2 = 3/2
Now that we have fractions that are easier to divide, one must understand that the opposite of dividing is multiplying. So if you multiply 12/5 by the reciprocal* of 3/2, which would be 2/3, you would get your answer so...
12 3 12 2 24 8 3
— ÷ — = — × — = — = — <em>or</em> 1 —
5 2 5 3 15 5 5
*the reciprocal is the opposite of the fraction you have. So the denominator would become the numerator, and vise versa.
