34.I
for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal
\frac{43}{20}


35.G
if you divide
58 \div 25 = 2.32
so G
\frac{58}{25}

36. C
\frac{5}{5}  = 1
so if you subtract
\frac{6}{5}  -  \frac{5}{5}
will equal

\frac{1}{5}
1 \frac{1}{5}

Mark can remember only the first 4 digits of his friend's phone number. He also knows that the number has 7 digits and that the
denis-greek [22]

Answer:

<em>19800 seconds, or 330 minutes, or 5 hours + 30 minutes</em>

Step-by-step explanation:

<u>Number Permutations</u>

We know the phone number has 7 digits, 4 of which are known by Mark. This leaves him 3 digits to guess with. We also know the last one is not zero. The number can be represented as

XXY

Where X can be any digit from 0 to 9 and Y can be any digit from 1 to 9. The first two can be combined in 10x10 ways, and the last one can be of 9 ways, this gives us 10x10x9 = 900 possible permutations.

If each possible number takes him 22 seconds, every possibility will need

22x900=19800 seconds, or 330 minutes, or 5 hours + 30 minutes

Answer:

3

Step-by-step explanation:

The average rate of change is

f(x2) - f(x1)

-----------------

x2-x1

We want to find the change from 1 to 3

f(3) = 8

f(1) = 2

f(3) - f(1)            8-2             6

----------------- = ------------ = ---- = 3

Red ribbons are wrapped around all the columns of a building. Each ribbon does not overlap itself. Each column has a radius of 3
Roman55 [17]

Hello!

If this long ribbon measures 144\pi feet, you can see, it was only multiplied by one number, which has the be the diameter of a column to get our circumference. If we divide this by our diameter 6 (diameter is double the radius, 3), we get our answer below.

144/6=24

Therefore, our answer is C) 24.

I hope this helps!
