About 260 because 202 plus 57 equals 259 and that'll round to 260

The formula for the size of a file that was downloaded over time t and at an average rate r is r.t.

lakkis [162]

Answer:

The size of file downloaded is 88 megabytes.

Step-by-step explanation:

Given that:

Average rate of downloading the file = $r$

Time taken to download = $t$

Formula for the size of file downloaded = $r.t$

Rate of downloading, $r = 800\ kilobytes/sec$

Time taken, $t$ = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded = $r.t$

Size of file downloaded = 800 kilobytes seconds $\times$ 110 seconds =

88000 kilobytes.

Now, let us convert the unit kilobytes to megabytes to find the answer.

Conversion formula:

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = $\frac{1}{1000}$ megabytes

88000 kilobytes = $\frac{1}{1000} \times$ 88000 megabytes

$\Rightarrow$ 88 megabytes.

Therefore, the size of file downloaded is 88 megabytes.

How do you solve the inequality 6y+3> -18x

Alex17521 [72]

$6y + 3 \ \textgreater \ - 18 x$

Subtract 3 from both sides:

$6 y + 3 - 3 \ \textgreater \ - 18 x - 3$

$6y \ \textgreater \ - 18 x - 3$

Dividade both sides by 6 :

$\frac{6y}{6} \ \textgreater \ \frac{-18x-3}{6}$

$y \ \textgreater \ \frac{-18x-3}{6}$

hope this helps!

Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?

frutty [35]

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

$\frac{1}{2}$ of 7.30 = $3.65$

Hope this helps you!

Hey!!!!

Here's your answer:

Solution:

A={2,3,4,5}

B={5,6,7,8}

 A U B={2,3,4,5} U {5,6,7,8}

 ={2,3,4,5,6,7,8}

In case of Union,we have to list all the elements which are present in both sets.

Hope it helps...
