Answer:
Part A: Kimberly
Part B:
Becca = 22.5 miles, Kimberly = 25 miles
Step-by-step explanation:
Part A:
Given that Becca runs at a constant speed of 4.5 miles per hour, use the table to find the constant speed that Kimberly runs, and compare who runs faster.
Let x = time
y = distance
k = speed = y/x
Equation for each person can be written as: y = kx
Therefore:
✔️Equation for Becca if k = 4.5
y = 4.5x
✔️Find k (speed) of Kimberly using (2, 10):
Speed (k) = y/x
k = 10/2
k = 5 miles per hour
Equation for Kimberly would be:
y = 5x
Comparing their speed, Kimberly runs faster because she covers more miles per hour than Becca does.
Part B:
For Becca, substitute x = 5 into Becca's equation, y = 4.5x
Thus:
y = 4.5*5 = 22.5 miles
For Kimberly, substitute x = 5 into Kimberly's equation, y = 5x
Thus:
y = 5*5 = 25 miles
Answer:
C)12 x 108 has the closest value.
Step-by-step explanation:
Firstly, (7 x 108) + (5 x 105) is equal to 756 + 525 which is equal to 1281.
A)7 x 108= 756
B)12 x 1013= 12156
C)12 x 108=1296
D)7 x 1013=7091

Answer:
Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.
Step-by-step explanation:
It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.
We have to find the expression which represents the perimeter, in centimeters, of the triangle.
Perimeter of a triangle = Sum of its all the sides.
On combining like terms, we get
Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.
Since there should be 180 in a tringle the bottom triangle woul be 65 65 50. assuming that the lines / and \ are the same in both traingles that means that at intersection they create the same angles above=below and left=right meaning the answer to x is x=50
