Answers

Answer 1
CD can be called DC, since each letter represents a point on the line. If the line segment has two points, it may be referenced with the points in any order. In the same way, a segment with points A and B could be called AB or BA.

Given the lengths of two sides of a triangle, find the range for the length of the third side (between what two numbers should the length of the third side be). Write the inequalities for each case. 11.5 and 23.6

Answers

The shortest the third side can be is the difference of the other two sides:
.. 23.6 -11.5 = 12.1
The longest the third side can be is the sum of the other two sides:
.. 23.6 +11.5 = 35.1

12.1 < third side < 35.1

Final answer:

To determine the range for the length of the third side of a triangle with side lengths 11.5 and 23.6, we apply the triangle inequality theorem which tells us that the third side must be greater than 12.1 and less than 35.1.

Explanation:

To find the range for the length of the third side of a triangle when given the lengths of two sides, one must use the triangle inequality theorem. This theorem states that the length of any side of a triangle is less than the sum of the lengths of the other two sides but greater than the absolute difference between these lengths. Given the side lengths of 11.5 and 23.6, the inequalities would be:

The length of the third side must be greater than the absolute difference between 23.6 and 11.5, which is 12.1. Therefore, the third side > 12.1.The length of the third side must also be less than the sum of 23.6 and 11.5, which is 35.1. Therefore, third side < 35.1.

Combining these inequalities gives us the range: 12.1 < third side < 35.1.

CAN SOMEONE PLEASE ANSWEERRRRRR

m∠3 + m∠4 = 180°
m∠2 + m∠4 + m∠6 = 180°
m∠2 + m∠4 = m∠5
m∠1 + m∠2 = 90°
m∠4 + m∠6 = m∠2
m∠2 + m∠6 = m∠5

Answers

m∠3 + m∠4 = 180°
As these 2 angles make up a straight line, the sum of the magnitude of angles is 180° so this is true 

m∠2 + m∠4 + m∠6 = 180°
these 3 angles are the interior angles of a triangle. the sum of all the interior angles of a triangle sum up to 180° so this is true.

m∠2 + m∠4 = m∠5
for this statement, use the previously stated concepts 
m∠2 + m∠4 + m∠6 = 180°
m∠5 + m∠6 = 180°
since both equations are equal lets put them into one equation
m∠2 + m∠4 + m∠6 =m∠5 + m∠6
since m∠6 is common for both sides lets cancel it out which leaves us with 
m∠2 + m∠4 = m∠5
therefore this statement is true 

m∠1 + m∠2 = 90°
sum of the angles making up a straight line is 180 °, therefore this is incorrect

m∠4 + m∠6 = m∠2
lets use the following equation
m∠2 + m∠4 + m∠6 = 180° 
if m∠6 + m∠4 = m∠2
then using this we substitute in the previous equation
m∠2 + ∠m∠2 = 180°
m∠2 = 90°
so this angle should be a right angle, but in the diagram its not a right angle therefore this is incorrect 

m∠2 + m∠6 = m∠5
since 
m∠5 + m∠6 = 180°
m∠2 + m∠4 + m∠6 = 180° 
then putting both the equations in one as they are both equal
m∠2 + m∠4 + m∠6 = m∠5 + m∠6
this shows that 
m∠2 + m∠4 = m∠5 
then m∠4 should be equal to m∠6
but judging from the sides opposite to the angles m∠4 and m∠6 the sides aren't equal so these angles too cannot be equal so this statement is wrong.
m∠3 + m∠4 = 180°
m∠2 + m∠4 + m∠6 = 180°m∠2 + m∠4 = m∠5

Cory has a square piece of wood that is 4.5 feet by 4.5 feet. He wants to make a circular tabletop out of it. What is the area of the largest circle that he can cut out of the wood? Round to the nearest tenth.

Answers

In this circle, the diameter is the same as the length of the side of the square.  The diameter is 4.5 ft; so, the radius is 2.25 ft., so. A πr²= π(2.25)²=15.90 ft²

The area of the largest circle is  15.9 feet^2

what is area ?

The area is the amount of space within the perimeter of a 2 D shape. It is    measured in square units, such as cm², m², etc.

formula used to find the area is :

A = π r^2

Given : diameter = 4.5 feet

r = d/2

⇒ 4.5 / 2

You work for a landscaper that has a customer needing to seed an area of land 80 feet by 40 feet in size. The garden center has 5-pound bags of grass seed. Each bag of seed can cover 25 square yards of land.

You calculate that the area you need to seed is 3200 square feet. You divide by 25 to find that you need 128 bags to seed the area. Is this correct?
A) Yes.
B) No, you need to convert the 3200 square feet to yards by dividing by 3. Then calculate the number of bags.
C) No, you need to convert the 3200 square feet to yards by dividing by 9. Then calculate the number of bags.
D) No, you need to convert the 3200 square feet to yards by multiplying by 9. Then calculate the number of bags.

Answers

1 yard = 3 feet
(1 yard)^2 = (3 feet)^2 ... square both sides
1 yard^2 = 9 feet^2
which means 1 square yard is equal to 9 square feet
think of a square yard as a 3x3 square where each smaller square is 1 square foot.

To convert from square feet to square yards, we multiply by the conversion factor (1 yard^2/9 feet^2). Or put simply we multiply by 1/9 which is the same as dividing by 9

This is why the answer is choice C.

Answer:

Since the mulch is measured in yards you need to either convert the area to be seeded to yards or the bag to feet. No, you need to convert the 3200 square feet to yards by dividing by 9. Then calculate the number of bags.

Mantids come in many shapes and sizes and are found all over the world. Some have patterns on their bodies that help them look like the ground. Some are bright green to blend in with leaves and plants. One special mantis is bright pink and looks like an orchid. The mantis is such a strange and engaging creature that many people keep them as pets. For many reasons, mantids have fascinated humans for many years. First, mantids show an amazing mastery of hunting skills. Mantids eat a wide variety of insects, including moths, crickets, bees, flies, grasshoppers, other mantids, and even, on occasion, small birds and snakes. They can capture prey many times larger than they are. Their powerful armor and amazing hunting skills make them quite effective. They have large powerful front legs, with spikes that help them hold on to prey. Their head can turn almost entirely around to follow prey without moving. Their front legs are so powerful and so fast that it is hard to see them move when capturing prey. One second their legs are empty and the next they are clutching tightly to something they have caught. Mantids are also stealthy. They wait, very still, very patiently for prey to come into sight. They also make slight swaying movements, to mimic leaves and grass moved by the wind. They focus intently on their victim. Then they pounce, suddenly, rarely missing their target. They are so successful they can triple in size every few months by molting when they outgrow their exoskeletons. They start out as nymphs, able to capture only prey that is smaller than they are. They end their lives about a year later becoming predators that can take down prey as large as hummingbirds. Finally, they are very personable, as far as insects go. They have a large, triangular-shaped head with large eyes. This alien-like appearance makes them quite cute. When you come across them in the garden, you can tell right away they are aware of you. They follow your movements as if to assess if you are either something to eat or something that will eat them. The little ones will accept rides on your finger if you are gentle. But be carefulthey can jump surprisingly far even when small. If they think your freckle is prey, you may be surprised to find a mantis on your nose. As far as predatory insects go, the mantis is one of the most impressive. Gardeners love to find them in on vegetables because mantids eat many insects that damage crops. However, they may also eat some insects that help a gardenerlike bees. Regardless, the mantis is a fascinating insect, and if you happen to see one hunting in the wild, consider yourself lucky. Which line from the text provides specific support for the idea that mantids are excellent hunters? First, mantids show an amazing mastery of hunting skills.
