Step-by-step explanation:
to under stand this think of a rectangle, or square. that's the yard, then
we know the total area of that rectangle or square, some how. :/ they just tell us, then they tell us the length , or one side of our rectangle or square.
we just have to find the other side.
area of yard (rectangle) = Length * Width
area = L * W
81 = 12 * W
use your algebra skills... ( my calculus prof. tells us that we are all bad at it :))
81/12 = W
6.75 = W
the width of the yard is 6.75 meters

What do you remember about types of angles?
An acute angle is one that measures LESS than 90˚
An obtuse angle is one that measures between 90˚ and 180˚
A reflex angle is an angle that measures between 180˚ and 360˚
There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.

The area of a circle
Answer:
area of the circle = 36π cm²
But area of a circle = πr²
Which means,
πr² = 36π
r² = 36π/π
r² = 36
r = √36 = 6 cm
Radius = 6 cm

Using proportions, it is found that the percentage of the people surveyed own a bird is given by:
C. 6%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. When the proportion is multiplied by 100%, a percentage is found.
The proportion of people who own a bird is:
p = 0.04 + 0.02 = 0.06.
Hence the percentage is of 6%, which means that option C is correct.

Jason is cutting 25 pieces of firewood every 15 minutes. At that rate, approximately how many pieces of firewood will Jason cut in 35 minutes?
Answer:
Approximately 58 pieces can be cut in 35 minutes.
Step-by-step explanation:
Jason is cutting 25 firewood pieces in 15 minutes
Therefore, per minute rate of cutting firewood will be,
Rate = [tex]\frac{\text{Amount of firewood to be cut}}{\text{Time taken}}[/tex]
= [tex]\frac{25}{15}[/tex]
= [tex]\frac{5}{3}[/tex] pieces per minute
By this rate amount of firewood that can be cut = Rate × Time taken
= [tex]\frac{5}{3}\times 35[/tex]
= 58.33
≈ 58 pieces of firewood
Therefore, approximately 58 pieces can be cut in 35 minutes.

Find the measure of the (2y-1)° angle
Answer:
69 degrees
Step-by-step explanation:
1) Find x
The angles measured x degrees and (x-28) degrees have a sum of 180 degrees because straight lines always have a measure of 180 degrees. Knowing this, construct the equation:
[tex]x+x-28=180\\2x-28=180[/tex]
Add 28 to both sides
[tex]2x-28+28=180+28\\2x=208[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}= \frac{208}{2} \\x= 104[/tex]
Therefore, x is equal to 104 degrees.
2) Find the measure of the (x-28) degree angle
Plug x into x-28
[tex]x-28\\= 104-28\\= 76[/tex]
Therefore, the measure of this angle is 76 degrees.
3) Find y
All the interior angles in any triangle will add up to 180 degrees. Knowing this, we can construct another equation:
[tex](2y-1)+76+y= 180[/tex]
Open up the parentheses
[tex]2y-1+76+y= 180\\3y+75= 180[/tex]
Subtract both sides by 75
[tex]3y+75-75=180-75\\3y=105[/tex]
Divide both sides by 3
[tex]\frac{3y}{3}= \frac{105}{3} \\y=35[/tex]
Therefore, y is equal to 35 degrees.
4) Find the measure of the (2y-1) degree angle
Plug y into 2y-1
[tex]2y-1\\= 2(35)=1\\= 70-1\\= 69[/tex]
Therefore, y is equal to 69 degrees.
I hope this helps!
