15 is 16.66666 percent of 90.
Answer:
The answer would be 30m squared.
Step-by-step explanation:
Multiply side and base and diveide by two.
Answer:
Part A - D:8
Part B - C:140°
<h3>Solving/Reasoning:</h3>
Part A: Vertical angles are always congruent.
Part B: If angles are supplementary, they need to equal 180 when added together. Since we know angle A is 40, we can subtract it from 180 and figure out what is left over that should be angle B.
40+B=180
B=180-40
B=140
Answer:
The speed of River's mom drove for 10 miles distance is 0.234 mph.
The speed of River's mom drove for 25 miles is 10.234 mph.
Step-by-step explanation:
Given as :
The first distance cover by River's mom = 10 miles
The rate of speed = x mph
The second distance cover by river's mom = 25 miles
The rate of speed = x + 10 mph
The total driving time = 45 min
Now, According to question
So,
Now dividing by 5 on both side we get;
Solving this quadratic equation we get;
Since speed cannot be in negative hence we will consider x= 0.234
So, The speed for 10 miles distance = x = 0.234 mph
and The speed of 25 miles = x + 10 = 0.234 + 10 = 10.234 mph
Hence The speed of River's mom drove for 10 miles distance is 0.234 mph
and The speed of River's mom drove for 25 miles is 10.234 mph
