Answer:
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4
Step-by-step explanation:
A bicyclist rides the same number of miles every minute. The ratio table below shows the number of miles she rides during certain amounts of time.
Biking Times and Distances
Number of Minutes Number of Miles
10 2.5
16 4
? 7.5
48 12
Which statement explains how to find the number of minutes it takes to bike 7.5 miles?

Answer:
Step-by-step explanation:
For a right triangle, the side that is opposite of the right angle is called the hypotenuse. This side will always be the longest side of the right triangle. The other two (shorter) sides are called legs.
Answer:
7 cookies
Step-by-step explanation:
We have 3 brothers
First , Second, Third
Let the total number cookies be represented by A
1 cookie = 1
Working backwards, we start from the third brother
If we work backwards
It means he gave everything away
We start from the youngest
He was given 1/2 of what was left and 1/2 a cookie
This means,
1/2 + 1/2 = 1
The second brother
He got half of what is left and 1/2 a cookies
Half of what is left from brother
= What the youngest brother got + 1/2 + 1/2 a cookie
= 1 + 1/2 + 1/2
= 1.5 + 1/2
= 2 cookies
For the first brother
He got 1/2 of the cookies + 1/2 cookie
= 1.5 × 2 + 1/2 + 1/2 cookies
= 3 1/2 + 1/2
= 4 cookies
The first brother got 4 cookies
The second brother got 2 cookies
The third broth got 1 cookies
Look at attached photo
first divide each line into the number as shown in the denominator
Part A: The equation of the ship's path is 
Part B: The two ships sails perpendicular to each other.
Explanation:
Part A: It is given that
and point (2, 5)
Substituting these in the slope intercept form, we have,


Thus, the equation of the ship's path in slope intercept form is 
Part B: The equation of the second ship is 
Let us bring the equation in the form of slope intercept form.

Thus, from the above equation the slope is 
To determine the two ships sailing perpendicular to each other, we have

where
and 

Since, both sides of the equation are equal, these two ships sails perpendicular to each other.
