For the scientific notation, write the standard form: 5.61 x 102
Alekssandra [29.7K]

<em>I believe the exponential form above is 5.61 x </em>10^{2}

Answer:

561

Step-by-step explanation:

A<em> "scientific notation"</em> is being used in order to express large numbers in its <u>simplest form</u>. This is commonly used in careers that use Mathematics very often like<em> engineers</em> or<em> scientists </em>because it makes their computation easier.

The<em> "standard form"</em> refers to the standard or traditional way of writing the numbers.

In order to get the standard form above, you have to check the <em>"power of the number 10." </em>The exponent above is 2. This means that you have to move the decimal point of 5.61 to the<em> right twice.</em> So, the answer is 561.

How many soultions? -4x-7+10x=-7+6x
hammer [34]

Answer:

C. Infinitely many solutions.

Step-by-step explanation:

-4x - 7 + 10x = -7 + 6x

Combine like terms on the left side. Rearrange the right side.

6x - 7 = 6x - 7

Add 7 to both sides.

6x = 6x

Subtract 6x from both sides.

0 = 0

0 = 0 is a true statement.

Both sides are equal, so all real values of x make the equation true.

Answer: C. Infinitely many solutions.

A nursery sells plants in flats. There are 6 plants in each tray. Each flat has six trays. The nursery sold 18 flats on Saturday
marshall27 [118]

For this case we have to:

There are 6 plants per tray.

There are 6 trays for each flat, so for each flat there are 6 * 6 = 36 plants.

Saturday day:18 flat * 36 plants = 648

Thus, on Saturday they sold 648 plants.

Sunday: 21 flat * 36plants = 756

Thus, on Saturday they sold 756 plants.

Thus, in total 648 +756 = 1404plants were sold.

Answer:

648 +756 = 1404 plants were sold.
