Answer:

25

Step-by-step explanation:

In her first 5 days, she reads 80 pages. That means that per day, she reads 16 pages. Then, she had 400 pages left, since 480-80 = 400.

So, you divide 400/16 = 25 days.

Find the annual interest rate. $I=\$160$ , $P=\$2000$ , $t=8$ months The annual interest rate is %.
Sedaia [141]

Answer:

1\%

Step-by-step explanation:

Simple interest (I) = $160

Principal amount (P) = $2000

Time period (t) = 8 months

Let R denotes rate of interest.

Relation between simple interest, principal amount, time and rate of interest  is given by I=\frac{PRT}{100}

160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%

What is the smallest integer greater than the square root of 68?
Talja [164]
This question is essentially just determining whether you understand the definition of integers and square roots. The square root of a quantity is a number that when multiplied with itself gives that quantity. The square root of 68 is expressed as:

√68 = 8.25

The square root of 68 is roughly 8.25. Now, an integer is simply a whole number, which is a number that is not a fraction. Therefore, the smallest integer that is greater than 8.25 is simply the next whole number, which is 9.

The smallest integer greater than the square root of 68 is 9.

A certain computer loses half of its value every two years. If the value of the computer after 3 years is 425, what was the init
IrinaVladis [17]

Answer:

1,700      

Step-by-step explanation:

The computation of the initial value of the computer is shown below:

Let us assume the value of a certain computer in the first year is X

In the second year, it is \frac{X}{2}

In the third year, it is \frac{X}{2}

In the fourth year, it is \frac{X}{4}

Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

\frac{X}{4} = 425

So, X = 1,700

Hence, the initial value of the computer is 1,700
