Gloria earned a total of $810 over the summer. She earned $162 babysitting and the restfrom mowing lawns. Which bar model and solution represent x, the amount of money Gloria
earned mowing lawns?

Answers

Answer 1

Answer:

Let x represent the amount of money Gloria earned mowing lawns.

We have been given that Gloria earned a total of $810 over the summer. She earned $162 babysitting and the rest from mowing lawns.

The total amount earned by Gloria would be amount earned from baby sitting and lawn mowing that is $x+162$ .

Now we will equate total earnings of Gloria by 810 as:

$x+162=810$

$x+162-162=810-162$

$x=648$

Therefore, Gloria earned $648 from mowing lawns.

What is the length of material in yards delivered by a roll with a speed of 290 rpm and a diameter of 46 mm? (Note: assume the roll turns for 90 seconds.)

Answers

Answer:

The length of material is 68.7 yards.

Step-by-step explanation:

If the material is delivered in a roll, we can calculate how many material is delivered by turn (one rotation). In one turn it delivers (π*D) of material, its perimeter.

If the diameter is 46 mm, in one turn the material delivered is

$m=(\pi*D)=3.14*46mm=144.44 mm/rev$

As we know the rotational speed, we can calculate the amount of material delivered by unit of time:

$m=144.44 (mm)/(rev)*290(rev)/(min)= 41,887.6(mm)/(min)$

If the roll turns for 90 seconds (or 1.5 min) we can calculate

$m=41,887.6(mm)/(min)*1.5min=62,831.4mm$

As we need the result in yards, we can convert (1 yard=914.4 mm)

$m=62,831.4mm*(1yard)/(914.4mm) =68.7 \,yards$
