1 answer:

Sliva [168]3 years ago

6 0

The value of the digit in the tenths place is 7. The value of the digit in the hundredths place is 7. The first number to the right of the decimal is in the tenths place and the second number to the right is in the hundredths place. The 0 is in the ones place and is the first number to the left of the decimal.

Hope this helps!

A floppy disc can store 1440000 bytes of data

max2010maxim [7]

Answer:

$1440000 = 1.44\times 10^{6}$

We need approximately 1667 floppy disc to store $2.4\times 10^9$ bytes of data.

Step-by-step explanation:

We are given the following information in the question:

A floppy disc can store 1440000 bytes of data.

We have to convert 1440000 in a standard form.

Standard Form:

Standard form is a way of writing down very large or very small numbers easily.
It helps us to express large numbers in powers of 10

The standard form can be written as:

$1440000 = 1.44\times 10^{6}$

We have positive power of 10 because we have to move to the right of the decimal point.

A hard disc can store $2.4\times 10^9$ bytes of data.

Number of floppy disks needed to store the $2.4\times 10^9$ bytes of data =

$\displaystyle\frac{\text{Data Stored}}{\text{Data store by 1 floppy disk}}\\\\= \frac{2.4\times 10^9}{1.44\times 10^6} = 1.66667\times 10^{(9-6)} = 1.66667\times 1000 = 1666.67 \approx 1667$

Thus, we need approximately 1667 floppy disc to store $2.4\times 10^9$ bytes of data.

a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4

Norma-Jean [14]

Answer:

Option b which is $2x^2+6x+3=0$

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is $-x^2+8x+2=0$

Discriminant from the equation we will find by the formula

$D=b^2-4ac$

Here, a=-1,b=8 and c=2 on substituting the values we will get

$D=8^2-4(-1)(2)=72$

Hence, option a is incorrect.

Now, we will consider option b which is $2x^2+6x+3=0$

Here, a=2,b=6 and c=3 on substituting the values we get

$D=(6)^2-4(2)(3)=12$

Hence, option b is correct

Therefore, option b is the required answer.

Select all the pairs that could be a reasonable approximation for the diameter and the circumference of a circle explain your re

Lady_Fox [76]

Answer:

The answer is "19 inches and 60 inches".

Step-by-step explanation:

Throughout this question, the choices were missing that's why its correct solution can be defined as follows:

The formula for diameter= $d=2r$

The formula for circumference = $C=2\pi r$

let the r=9.5 so, the diameter and the circumference are:

$\to d= 2 r= 2\times 9.5 =19\\\\\to C= 2 \pi r= 2\times \frac{22}{7} \times 9.5 =59.71 \approx 60 \\\\$
