Answer:
$15 for a lawn, $105 for seven lawns.
Step-by-step explanation:
The question is about the direct ratio problem. Logically, you will earn more if you mow more lawn.
The scheme for this ratio is given below:
15 n_________n lawns
x_________ 1 lawn
You will earn 15 dollars for mowing a lawn
When you mow 7 lawns, the scheme will be in this manner:
15 n__________n lawns
x__________7 lawns
You will earn 105 dollars
4.5 meters = in 9 seconds
1 meter = 9/4.5 = 2seconds
so, a bee flys 1 meter in 2 seconds.
Answer:
The length of each side is (2a-5) units
Step-by-step explanation:
4a^2 - 20a +25
= (2a)^2 - 20a + (-5)^2
=(2a - 5)^2
(9a^2 - 16b^2)
= (3a)^2 - (4b)^2 this is the difference of two squares, the factors are therefore
= (3a + 4b) * (3a - 4b)
The dimensions of the rectangle are:
one pair of opposite sides are 3a + 4b
and the other pair of opposite side perpendicular to the first pair is 3a - 4b

Step-by-step explanation: take deep breath breath in deeply and breath out deeply no ball up ur fist for 3 secs 123 no relax them
Area of big rectangle= 35x22=770
Area of little rectangle = 18x(44-35)=162
Area of triangle = 1/2 (44-35)x (22-18) = 18
Area of polygon= 770+162+18= 950m^2
