Jon has a faster rate. 64/4 = 16, and 45/3 = 15
Answer:
Step-by-step explanation:
Let x represent the distance travelled by the helicopter and the plane.
Let t represent the time it takes the the helicopter to travel x miles
Speed of the helicopter is 180 miles per hour.
Distance travelled = speed × time
x = 180t
Twenty minutes later, a plane leaves the airport and follows the helicopter at 330mi/hr. Converting 20 minutes to hours, it becomes 20/60 minutes
Time taken for the plane to travel x miles is t - 20/60
x = 330(t - 20/60)
Before the plane overtakes the helicopter, they would have travelled equal distance. Therefore
330(t - 20/60) = 180t
330t - 110 = 180t
330t - 180t = 110
150t = 110
t = 110/150 = 0.73 hours
Answer:
8 square units
Step-by-step explanation:
First, split this figure into 3 known figures:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 2 unit triangle
Then solve all these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 2 = 4 / 2 = 2
Then add all these areas:
2 + 4 + 2 = 8
Answer:
C) 4
Step-by-step explanation:
Just follow the same steps as the last one.
32x+2 = 33x-2
2+2=33x-32x
4=1x
X=4
Answer:
B) 40 feet
Step-by-step explanation:
Essentially, there are two similar right triangles in the given problem.
base_<em>L </em> = Base [larger triangle] = 60 ft
base_<em>S </em> = Base [smaller triangle] = 6 ft
x = leg (larger triangle)
y = leg (smaller triangle) = 4 ft
Using the given proportion to solve for the value of x:
6x = 240
Divide both sides by 6:
6x/6 = 240/6
x = 40
