D) It's a decimal that terminates after 3 decimal places.
7 ÷ 8 = 0.875
Answer:
Hope this helped
Step-by-step explanation:
Circumference = 750 m / 3
Circumference 250 m
Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters
Solving for the diameter
250 m = pi * D
D = 250 m / pi
D = 79.58 m is the diameter of the circular field
Solving for the radius
r = 1/2 D where r is the radius of the circular field
r = 39.59 m is the radius of the circular field
first car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
Here is your answer and result
Have a nice day
Answer: a and d
Step-by-step explanation:
(to find all points of discontinuity, set denominator equal to zero and solve)
(to factor, find two numbers when added together equal -7 and when multiplied together equal 10)
-2 + -5 = -7
-2(-5) = 10
-2 and -5 are the two numbers
