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.

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

Answer:

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

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.

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.

Using proportions, it is found that the percentage of the people surveyed own a bird is given by:

C. 6%.

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.

There are 75 lasagna dinners are likely to be needed for a flight with 360 passengers.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

An airline food service finds that a recent flight of 120 passengers ordered dinner as depicted in the table to the right.

Here, Number of Lasagna for 120 passengers = 25

Hence, For 360 passengers number of lasagna is,

⇒ 120 / 35 = 360 / x

Where, x is umber of lasagna for 360 passengers

⇒ x = 360 × 25 / 120

⇒ x = 75

Thus, There are 75 lasagna dinners are likely to be needed for a flight with 360 passengers.
