Answer:1.55 Km

Step-by-step explanation: She hiked 4.75 Km of 6.3 Km, so we subtract.

Remember to add a 0 next to three, and arrange the decimal points so there are one above another. Also remember to put the greater number on top of the smaller, and if a digit on top is smaller than the bottom, carry from the right. This is the most important thing: DO NOT FORGET THE DECIMAL POINT!

the local hardware store wants to increase their inventory. Last year 15 electric screwdrivers cost them 300.how much would 45 s
Harman [31]
One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x).    Solve this equation for x.  To do this, you might try multiplying both sides of this equation by x to eliminate fractions.

Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.

Help me pls. I need help with the question
likoan [24]

Answer:

$173.90

Step-by-step explanation:

The most obvious way to answer this question is to multiply $9.40 by 18.5

This would result in 173.90.

But I realize nobody like to deal with decimals in a multiplication problem, so here's the way I would do it (<em>especially if you don't have a calculator!</em>)

The strategy is to break it down!

Multiply $9.40 x 18 hours to start, since this is easier.

9.4 x 18 = 169.2

So, that's $169.20 for 18 hours of work.

We aren't finished, because Abdel worked for 18.5 hours.

So, what half of $9.40?

9.4 / 2

= 4.7

-or-

$4.70

So, knowing that Abdel makes $4.70 in half an hour, lets just add that onto the $169.20 we got earlier.

169.2 + 4.7 = 173.9

-or-

$173.90 for 18.5 hours of work!
