Answer:

135

Step-by-step explanation:

1. divide 32 by 60 to get how many copies per second

32/60 = 0.533

2. convert 4min and 15 sec to seconds

it is 255 seconds

3. Multiply copies per second by number of seconds

0.533(255) = 135.91

4. Round down to whole number because you can't copy part of a paper

The Oregon trail is 2.197 miles long. How long would it take a covered wagon travelling 20 miles a day to complete the trip? Wri
Bess [88]

Answer: It needs 2.4 hours to complete the trip.

Step-by-step explanation:

Since we have given that

Length of Oregon trail = 2.197 miles

Speed at which it travel = 20 miles per day

we need to find the time taken by it ,

As we know that

Time=\frac{Distance}{Speed}

Time=\frac{2.197}{20}\\\\Time=0.10\text{ days}

So,

it will be changed into hours

1\text{ day}=24\text{ hours}\\\\0.1\text{ day}=24\times 0.1=2.4\text{ hours}

so, it needs 2.4 hours to complete the trip.

N (blank exponent) = 1/64 when n = 1/4
gizmo_the_mogwai [7]

Answer:

The blank exponent is 3

Step-by-step explanation:

It is given that n^x=1/64 where n=1/4

1/4^x=1/64

1/4*1/4*1/4=1/64, so x=3 works as a solution. You could use logarithms, but it makes things more difficult, especially in this case.

B- They are always congruent. Congruent means in agreement or harmony. But in this case, identical in form. Parallelograms are parallel on both sides, which makes them have congruent sides. 
P.S.- This is elementary level, no offense.
