Answer:
94
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion to find KY.
Cross multiply to solve for KY.
95.2(KY) = 168(34)
95.2KY = 5,712
KY = 60
Add KY to 34 to find x.
60 + 34 = 94.
Answer:
One of the number is 4 while the other is 7
Step-by-step explanation:
The sum of two numbers is eleven
Let the numbers be x and y
X+ y = 11
One number is thirty-eight less than six times the other
X= 6y-38
X+ y = 11
6y-38 +y= 11
6y+y= 11+38
7y=49
Y= 49/7
Y= 7
X+ y = 11
X+7= 11
X= 11-7
X= 4
3.96 ft
Step-by-step explanation:
An freely-falling object dropped from a certain height travels a distance equal to
h = -16t^2
where t is the time elapsed. So after 1.3 s, the ball has traveled
h = -16(1.3)^2 = -27.04 ft
This means that after 1.3 s, the ball is 31 - 27.04 = 3.96 ft above the ground
Answer:
15 miles
Step-by-step explanation:
Speed of John biking = 10 miles per hour
Time taken by John to travel the route = 1.5 hours
We know that
distance = speed * time
now that we know time and speed for John
we can distance by using the above formula
distance = 10 miles per hour* 1.5 hour = 15 Miles
Thus, the route was 15 miles long.
