Step-by-step explanation:

Answer:

Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.

Answer:

m∠DEF = 135º

Step-by-step explanation:

1. I will find the answer to X by writing what ∠FEA, ∠AEB, ∠BEC by doing

(2x+5) + (4x) + (3x-5) = 180, all simplified it will give me x=20

2. I want to figure out what ∠AEB and ∠BEC are

since x=20 and ∠AEB is 4x, we substitute x as 20 as : 4(20) which is 80.

We then figure out ∠BEC since x=20 and ∠BEC is 3x-5 we substitute the 20 in place of x, which will be 3(20) - 5= 55.

3. I want to add ∠AEB + ∠BEC to get the vertical angle of ∠DEF

(the vertical angel of ∠DEF is ∠AEB + ∠BEC)

∠AEB + ∠BEC = ∠DEF

80 + 55 = ∠DEF

135 = ∠DEF

Answer:

Right angled

Answer: Isosceles triangle.

Answer:

2x - 6y

Step-by-step explanation:

(5x – 2y) – (3x + 4y)

5x - 2y - (3x + 4y)

Distribute the - sign

5x - 2y - 3x - 4y

Group like terms

(5x - 3x) + (-2y - 4y)

Combine like term

2x - 6y

Answer:

The correct answer should be 5

Step-by-step explanation:

start at a point where the line passes through the vertex of the small grid box given and count how many units u need to go up and right to reach to the next point where the line passes in a similar way, since you need to find the rise, just count how many units u need to go up. The answer would be 5

Answer:

The slope of the trend line is 19.286 thousand dollars. This is important because it shows that the sales of this store is increasing which intern increases profits which is important for the long term viability of this store.They y-intercept is 53.571 thousand dollars. This number represents the profits of the store in 2010 and it serves as benchmark for future years. In fifty years, we assuming that the trend continues, it will be 19.286*50+53.571 = 1017.871 thousand dollars. However, this is not appropriate because a lot can change in 50 years which can have a profound impact on the future profits.

Step-by-step explanation:

Answer:

1) 7/8  

2) 0. 9

3) 88%

Step-by-step explanation:

total CDs =  2 + 9 +5 = 16

probability of Comedy is 2 out of the total 16

= 2/16

probability of not picking one would be 1 - 2/16 = 14/16 = 7/8

7 divided by 8 = 0.875   which rounds to 0.9

0.875 x 100 gives the percentage of 87.5% which rounds to 88%

Answer:

no do not agree

Step-by-step explanation:

No because 5 x 0.13 does not equal 6.5 it equals 0.65

The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. Ding  A single lap should be completed each time you hear this sound. Ding  Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, ding

Step-by-step explanation:

I think H is the best answer.

Answer:

1 hour

Step-by-step explanation:

First of all you multiply 20 by 5 to calculate the distance he travelled, which is 100 then you add 5 to 20 to get the new speed which is 25 finally you divide his distance by the new speed 100/25 which is 4 and as 5-4=1 he would have saved 1 hour.

Would be amazing if you marked brainliest :)

Answer:

65

Step-by-step explanation:

not that hard bro

Answer:

65

Step-by-step explanation:

25^2+60^2=x^2

625+3600=x^2

4225=x^2

[tex]\sqrt{4225}[/tex]=x

x=65

Answer: 17

Step-by-step explanation:The other side is the same length. So its 17 :)

Answer:

18.3 = The third side

Step-by-step explanation:

Using Pythagorean Theorem; since the triangle is a right angled triangle.

Pythagorean Theorem states: A² + B² = C² (Where C is the hypotenuse, the line on the triangle opposite to the labeled right angle of the triangle, A and B would be the other 2 sides).

=> A² + B² = C²

=> 17² + B² = 25²

=> 289 + B² = 625

=> B² = 625 - 289

=> B² = 336

=> [tex]\sqrt{B^2}[/tex] = [tex]\sqrt{336}[/tex]

=> B =  [tex]\sqrt{336}[/tex]

=> B = 18.3

Step-by-step explanation:

Commutative property of addition is given by : a+b = b+a , where a and b can be any expression of real numbers. It basically changes the order of the so that simplification of any expression becomes easier.

but it is with the stuff that you have on your computer or paper

Answer:

x = 30m

Step-by-step explanation:

GIVEN :-

There are 2 right-angled triangles.

In the triangle on the right side ,

In the triangle on the left side ,

TO FIND :-

FACTS TO KNOW BEFORE SOLVING :-

SOLUTION :-

In the triangle on the right side ,

[tex]Perpendicular = \sqrt{26^2 - 10^2} = \sqrt{676 - 100} = \sqrt{576} = 24m[/tex]

⇒ Perpendicular of the triangle on right side = Perpendicular of the triangle on left side.

In the triangle on the left side ,

[tex]Hypotenuse = \sqrt{24^2 + 18^2} = \sqrt{576 + 324} = \sqrt{900} = 30m[/tex]

∴ x = 30m

The equation for finding volume of a cylinder is V=πr2h. That means if you do (3.14)(25)(17) you would get your answer- 1334.5
