Answer:

60

Step-by-step explanation:

Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)

Answer:

1. 60

2. 120

3.30

Step-by-step explanation:

(Yes I know they aren't labeled one and two but I'll go in order from the questions)

1. It is 60, because it is an equilateral triangle so all angles are equal. 180/3=60.

2. There are two ways you can solve this problem. The first is using the vertical angle theorem. That makes it 120. Or, you can add all the angles you have already and remove it from 360.

360-120-60-60=120.

(you can tell it is not 60 because it is larger than a right angle in the picture)

3.x=30.The right angle is 90, and there is a 60 degree angle, so 90-60=30

[tex]A=100yd^{2}\\b=25yd\\h=______[/tex]

Answers

answer: 8yd

explanation:

using the equation provided, plug in all the know values

this would make the equation the following:

100 = 1/2 (25) h

first, multiple 1/2 by 25 to get 12.5

the equation should now look like this:

100=12.5h

since we are looking for what h is, we must isolate h by dividing both sides of the equation by 12.5

now the equation should look like this:

8=h

the answer is 8 yds

hope this helped!!
If base is 25 then what is 25 of a half is 12.5 know the area is 100 know you want to do is divided 100 by 12.5 is equal to 8 height= 8

Answer these two questions (repost bc last answer was wrong):
Suppose that 60% of the students at your school favor a proposed school policy that would ban cell phones at school. Also suppose that every student in your class selected a different random sample of 50 students from your school and calculated the proportion of students in the sample who favors the ban.

5. If your class constructed a dot plot of all these sample proportions, where would you expect the dot plot to be centered?

6. If every student had selected a random sample of size 25 instead of a sample of size 50, would you expect a dot plot of the sample proportions to be more spread out or less spread out than in a dot plot of sample proportions for samples of size 50?

find the area of the circle. Use 3.14 for π. do NOT round your answer.

Answers

A = pi*r^2, where r is the halfway distance of the line inside (diameter).

Diameter = 2r so 11 = 2r
r=5.5

A = 3.14*(5.5)^2
A= 3.14* 30.25
A= 94.985

Answer:

A≈95.03

Step-by-step explanation:

The Formula for an area of a circle is A=πr2

Becuase the Radius is half of the diameter then we would divide 11 by 2

which is 5.5

plug it in the equation

A =π (5.5)squared

square 5.5

A=30.25π

A= 95.0331777711

what is the relationship between each pair of corresponding?

35 7

25 5
20 4
15 3

Answers

Answer:

-5.1

Step-by-step explanation:

Each time is subtracting by 5.1

35.7 - 5.1 = 30.6

30.6 -5.1 = 25.5

25.5 - 5.1 = 20.4

20.4 -5.1 = 15.3

The corresponding relationship is times 5 because 7 times 5 = 35 and 6 times 5 is 30 and 5 times 5 is 25 and 5 times 4 is 20 and 5 times 3 is 15

Solve the expression 6 x one sixth + 11 x 2

Answers

Step-by-step explanation:

6 x 1/6= 1

11 x 2= 22

22+1= 23

6 x 1/6 + 11 x 2

Since multiplication comes before addition in PEMDAS, you’ll need to do multiplication first. The first multiplication in this expression is 6 x 1/6 which can also be written as 6/1 x 1/6

6/1 x 1/6 = 1

The second multiplication in this equation is 11 x 2

11 x 2 = 22

Now you can add both of the numbers and you’d get 23 :)

(GIVING BRAINLYIST) Read the excerpt from the article "The Wolves Among Us".


Wolves are exceptional pack hunters. This is why they are able to take down large prey such as moose or deer by working together as a seamless team. Wolf pups as young as eight months old begin helping on the hunt. Wolves can reach speeds of up to 40 miles per hour when chasing prey, and their thick, double-coated fur enables them to keep warm in even the coldest arctic temperatures. Their large, powerful paws can reach up to 5 inches across and help to propel them quickly across the snow.


Read the excerpt from the article "The Necessity of Hybrids":


Grolar bears and pizzlies are the result of crossing polar bears and grizzly bears. These hybrids were first seen in zoos, as the bears' natural habitats did not normally overlap. Recently, these hybrids have started appearing in the wild. Due to climate change, the bears' once-separate habitats are beginning to overlap. Bigger and more aggressive than their parents, grolar bears and pizzlies could pose a risk to natural habitats and humans.


Wolfdogs are, as their name suggests, the result of crossing a wolf with a domestic dog. Bred for the pet trade, these hybrids do not often happen in the wild. Wolfdogs do not make good pets, however, as they can be destructive and aggressive. Many states have outlawed keeping wolfdogs because they can pose a danger to people.

The surface area and volume of the given cylinder are 80π and 96π respectively.

What is a cylinder?

A cylinder is a combination of infinite circles with the same radius and keeps one up to up.

The surface area of the cylinder = πdh where h is the height of the cylinder and d is the diameter of the cylinder.

Given a cylinder with,

Radius = 4 yd

Height = 6 yd

The surface area is given as ;

⇒ 2π [ r² + rh ]

⇒ 2π [ 4² + 4 × 6 ]

⇒ 2π [ 40 ]

⇒ 80π

The volume of a cylinder is given as ;

⇒ πr²h

⇒ π (4)² 6

⇒ 96π

Hence "The surface area and volume of the given cylinder are 80π and 96π respectively".

Answer: 59.3 feet

Step-by-step explanation: we will multiply 11.711.77 ✖ 2.8✖1.8 equal 59.3208 so estimate the 2 can't give something to the 3 so 559.3 , hope my answer is correct

Answer: 2

Explanation:
Since you are finding the depth your formula will look like this

11.77= 2.8 x 1.8 x d
(d stands for depth since we don’t know the value)

To solve it you multiply 2.8 and 1.8 which equals 5.04

So now your equation looks like this
11.77= 5.04 x d

Next you divide 11.77 by 5.04 and get
2.33531746

This rounds to 2 so the answer is 2.
