Richard mows 1/3 of his yard in 1/2 hour. How much of his yard would Richard mow in 1 hour?

2 answers:

1/3 yard = 1/2 hr
x yard = 1 hr

Okay, so if 1/3 of his yard is mowed in half an hour, "x" of his yard is mowed in an hour.
1/3 yard is to 1/2 hr as "x" yard is to 1 hr

Solve by cross multiplying:
1/2x = 1/3 *1
1/2x = 1/3
(divide both sides by 1/2)
2/3

Richard can mow 2/3 of his yard in one hour.

You can also figure this out by just realizing that 1/2 hr multiplied by 2 would give you 1 hr and then multiply 1/3 by 2 but it's good to get into the habit of solving things algebraically (or so I've been told).

Which formulas can be used to find the surface area of a right prism where p is the perimeter of the base, h is the height of th

svp [43]

Let
ba--------> area of bases (the two bases included)
p---------> perimeter of the base
h--------> height of the prism
la-------> lateral area

we know that

[surface area]=2*[area of one base]+[perimeter of the base]*height
so
2*[area of one base]=ba
[surface area]=[ba]+[p]*h

and
the formula of lateral area is
[la]=[perimeter of the base]*height
[la]=[p]*h
therefore
[surface area]=[ba]+[la]

the answer is
[surface area]=[ba]+[p]*h
[surface area]=[ba]+[la]

Troy shares a family bag of 24 Jet Plane

nlexa [21]

Answer:

Troy ate 7 lollies.

Step-by-step explanation:

You start out by finding how many lollies Troy's two friends ate out of the 24 lollies. To find out how much Tane ate out of the 24 Jet Plane lollies you simply divide 24 by the denominator --> 24/3=8, then you multiply your answer by the numerator --> 8x1=8, so Tane ate 8 of the 24 lollies. Repeat this same process for Levi, and your answer should be 9.

Because Tane ate 8 out of the 24 lollies and Levi ate 9 out of the 24 lollies, that indicates that 17 out of the 24 lollies are gone (just add your results, 8+9=17). This leaves Troy with only 7 lollies (subtract 17 from 24 to find out how many lollies are left, 24-17=7).

There was a triangle ABC with sides 15, 20, and 10. One of the sides of a triangle, which is similiar to ABC is 60. What are the

wlad13 [49]

Answer:

The possible pairs of sides are 90 and 120, 30 and 45, and 80 and 40.

Step-by-step explanation:

We know that 60 is a multiple of 15, 20, and 30, so we multiply by each factor to find all possible pairs: 10x6=60, 20x6=120, and 15x6=90, that gives your first pair, 90 and 120.

We have now multiplied our first factor, 6. Now we need to multiply our second factor, 3: 20x3=60, 15x3=45, and 10x3=30. That gives your second pair, 30 and 45.

Finally, we need to multiply by our 3rd factor, 4: 15x4=60, 20x4=80, and 10x4=40. That gives you your final possible pair, 80 and 40.

I hope this helps :-)
