Is-0.62 greater than or less than -6/7
NNADVOKAT [17]
-6/7 = -0.85
-31/50 = -0.62
So -0.62 is greater than -0.85
-0.62 < -0.85
Because the bigger the fraction is the less it actually is and I think the same goes for decimals . Hope I helped

Brianna ran 6 laps around a circular track with the diameter of 120 feet how far did she run
Flura [38]

Answer:

2261.94671

Step-by-step explanation:

You must first find the circumference of the track. Using 2(pi)r.

Where pi=3.14... and r=radius

you can find the radius by dividing the diameter by 2, 120/2=60

Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515

Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671

NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377

Help, please!! What is x?? x/2+3/8=1
svetlana [45]

Answer:

8(x/2) + 8(3/8) = 1(8)

8(x/2)..the two cancels out and you are left with 4x

8(3/8)..the 8 cancels and leaves with 3

 

1(8)=8

4x+3=8

Subtract the 3 from both sides to get the x term alone

4x=5

Divide both sides by x to get alone

x=5/4
