In 1 hour he can mow 1/3rd of the lawn.
In 1 hour they can together mow (1/2+1/3)=5/6th of the lawn.
Together they can mow the lawn in 6/5 hours=1.2 hours.
I hope this helped, please mark Brainliest, thank you!!
Since HLI and HLG are complementary angles (add together to make 90 degrees), you can set them up in the equation (25m + 22) + (9m) = 90.
25m + 22 + 9m = 90 add like numbers
34m + 22 = 90 subtraction property
34m = 68 divide
m = 2
substitute m = 2 into the equation got angle HLG (25m + 22)
25(2) + 22
50 + 22
HLG = 72
The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².
<h3>What is the area?</h3>
The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.
The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).
Now, if the area of the composite figure is taken out it will be,
Thus, the area of the composite figure is 264 cm².

The square of 4 and 2 adds up to 20!
4 square is 16.
2 square is 4
So 16+4=20
7 3/4 feet / 3
You can convert 7 3/4 to 31/4 ( you multiply the 7 x 4 and then add 3 to get 31 still over 4 for the denominator. 31/4 * 1/3 = 31/12 = 2 7/12 feet
