1. Find the least common denominator (12).
3/4·3/3=9/12
1/3·4/4=4/12

2. Now you can subtract.
9/12-4/12=5/12.

So your answer is 5/12.

You need to find the common denominator first. 3 * 4 = 12
3/4 = 9/12 and 1/3 = 4/12
9/12 - 4/12 = 5/12

Sabrina rides her bike 2 miles to school each day she leaves her house 7:30 and arrives at 7:50 What is Sabrina's average speed
MakcuM [25]

6 mph.

To find this, create a ratio.

2/20 = x/60

This will allow you to compare here time of twenty minutes to an hour in the same context.

Multiply 2 by 60 and divide by 20 to get the answer of 6 mph.

Thus, Sabrina's average speed in miles per hour is six miles per hour.

Hope this helps!

Why do whole numbers raised to an exponent get bigger while fractions raised to an exponent get smaller
Brilliant_brown [7]

Answer:

when you multiply a whole number by itself it will obviously get bigger.

4 to the 2nd power equals 16 because 4x4 = 16

if you were to multiply a smaller number though, it wouldn't get as big.

Each number you put to the same exponent will not get bigger at the same rate since each number isnt being multiplied by the same thing.

ex. 4 and 6 are raised to the second power both dont get multiplied by the same number 4 is multiplied by 4, and 6 by 6, therefore the bigger the number the bigger it grows.

Fractions get smaller for this reason when you have the fraction 2/3 raised to the second, both numbers must be raised. 2 to the second equals 4 while 3 to the second is 9.

1/2 to the second would then equal 1/4 since 1 to the second equals 1 and 2 to the second equals 4.

Can you help me !!!!!
kari74 [83]

Answer:


Step-by-step explanation:

Okay, so hopefully my crude diagram helps you visualize the problem. When in doubt, always draw a picture.

All I did was graph the points and formed a line.

Slope: It's going to be 0 because it doesn't change at all (no different y values)

(y2-y1)/(x2-x1) = (6-6) / (4-2) = 0/2 = 0


Y intercept is where the line crosses the y axis- this is also where x=0 (find it in your chart!)

Equation is y= 6; I don't know how to explain this, but trust me, it's right
