Oliver and Ryan are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Oliver is 350 miles away from the stadium and Ryan is 365 miles away from the stadium. Oliver is driving along the highway at a speed of 60 miles per hour and Ryan is driving at speed of 65 miles per hour. Let O O represent Oliver's distance, in miles, away from the stadium t t hours after noon. Let R R represent Ryan's distance, in miles, away from the stadium t t hours after noon. Write an equation for each situation, in terms of t , t, and determine the interval of hours, t , t, for which Oliver is closer to the stadium than Ryan.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
