Answer:
1. The information from the problem illustrates the number of hours flo and bryan works jointly to mow the lawn.
2. The question demonstrates the numbers of hours worked by the two individuals i.e. flo and bryan to mow the lawn. Find the numbers of hours worked i.e h=? by flo and bryan to mow the lawn.
3. H/3+h/6=1
Take LCM i.e. (2H+H)/6=1
Now add H and and move the 6 on the other side and multiply, that becomes
3H=6
Now take 3 on the other side and divide by 6, which becomes the answer i.e. H=2.
4. Variables are H and values are the hours worked.
5. The problem in this question , why the number of hours are missing which we have to find and gives it a sense that how many hours needed to mow a lawn.
6. The time takes for both of them to mow lawn is 2 hours, which is flo works more than bryan to mow a lawn.
7. If you want to check that your anser is correct put the answer in the equation, if both sides come same then the answer is correct, for instance in the same quwstion where answer is H=2. Now put H in the equation i.e.
H/3+H/6=1
2/3+2/6=1
4+2/6=1
6/6=1
1=1
Hence proved. Enjoy :)
Answer:
15
Step-by-step explanation:
to get sides JK and ML, you have to use ratios. the ratio is 3:2 so therefor ml and jk are 4.5
Then you add 4.5 and 4.5 and 3 and 3 to get you 15
Answer:
114.8 cm^2
Step-by-step explanation:
<h2><u>Finding the area of the shape </u></h2>
we can break down this figure into individual shapes :
- rectangle
- triangle
- parallelogram
<h3><u>area of a triangle</u></h3>
formula:
<u>area of a triangle =25.2 cm^2</u>
<u />
<h3><u>area of a rectangle</u></h3>
formula:
4.5 * 8
<u>area of a rectangle = 36 cm^2</u>
<u />
<h3><u>area of parallelogram</u></h3>
formula:
1/2 * ( sum of parallel sides ) * height
1/2 * ( 8 + 8 ) * 6.7
<u>area of a parallelogram = 53.6 cm^2</u>
<u />
<h3><u>Total area</u></h3>
= area of rectangle + area of triangle + area of parallelogram
= 25.2 + 36 + 53.6
<h2><u>= 114.8 cm^2</u></h2>
