the coordinate grid below represents a town. Curtis's house is that - 4 - 6 engines house is at -4 3 plot the two points or Curt
is's house in Jean's house are located. each unit on the grid represents one mile. If Curtis can ride his bike at a constant rate of 12 miles per hour how many minutes would it take Curtis to ride from his house to Jean's house SHOW WORK
1 answer:
Curtis's house: (-4,-6)
Jean's house: (-4,3)
Distance: -6 to 3 = 9 miles
Curtis travels = 12 miles per hour
speed = distance / time
12 miles/hr = 9 miles / time
12 miles/hr * time = 9 miles
time = 9 miles * 1hr/12 miles
time = 0.75 hour
1 hour = 60 minutes
60 minuts * 0.75 = 45 minutes
It would take 45 minutes for Curtis to ride from his house to Jean's house
Jean's house: (-4,3)
Distance: -6 to 3 = 9 miles
Curtis travels = 12 miles per hour
speed = distance / time
12 miles/hr = 9 miles / time
12 miles/hr * time = 9 miles
time = 9 miles * 1hr/12 miles
time = 0.75 hour
1 hour = 60 minutes
60 minuts * 0.75 = 45 minutes
It would take 45 minutes for Curtis to ride from his house to Jean's house

Step-by-step explanation:
<u><em>The complete question is</em></u>
If the perimeter of a rectangle is 22 meters, and the perimeter of a right triangle is 12 meters (the sides of the triangle are half the length of the rectangle, the width of the rectangle, and the hypotenuse is 5 meters). How do you solve for L and W, the dimensions of the rectangle.
step 1
<em>Perimeter of rectangle</em>
we know that
The perimeter of rectangle is equal to
we have
so
Simplify
-----> equation A
step 2
Perimeter of triangle
The perimeter of triangle is equal to
so
Multiply by 2 both sides
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (8,3)
see the attached figure
therefore
The dimensions of the rectangle are
Length:8 m
Width:3 m
