A plane descends at a rate of 212 feet per minute. What will the total change in elevation be after 6 minutes?

Answers

Answer:

The total change would be 1272 feet

Step-by-step explanation:

Solve:

212*6= 1272

Check your work:

1272/ 6= 212

Hope this helps!

Answer:

1272

Step-by-step explanation:

If you multiply 212 by 6, you get 1272.

Because, since the rate is 212 and you want to know what the total change will be after 6 minutes, you multiply 212 by 6 and you get 1272 so, 1272 is your answer.

A prism and two nets are shown below:

Image of a right triangular prism and 2 nets. The triangle bases have base 4, height 3, and diagonal side 5. The length of the prism from the bases is 9.4. Net A has 3 rectangles in a row. The middle one has sides AC and CD. This middle one has triangle ABC on top and identical triangle below. Net B is the same except that the triangle base ABC is on top of the last rectangle which has sides AC and CD. Units are in inches.

Part A: Which is the correct net for the prism? Explain your answer.

Part B: Write the measurements of Sides AB, BC, and CD of the correct net.

Part C: What is the surface area of the prism? Show your work.

Answers

Part A: The correct net for the prism is net A.

Part B: AB = 3 in, BC = 5 in, CD = 9.4 in.

Part C: The surface area of the prism is 124.8 square inches.

What is triangular prism?

A triangular Prism is a pentahedron. It is a 3-D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The edges and vertices of the bases are joined with each other via three rectangular sides.

For the given situation,

The diagram shows the triangular Prism and the 2 nets for it.

Part A:

The correct net for the prism is net A. Net A suits the triangular Prism and it is fold-able along the net.

Part B:

The measurements of sides of the net are

[tex]AB, h=3in[/tex]

[tex]BC, S=5in[/tex]

[tex]CD,l =9.4in[/tex]

Part C:

Base of the triangular prism,b = 4 in

The three sides of the triangle is S1,S2,S3 = 3, 4, 5 inches.

The surface area of the prism is

[tex]A = bh+(s1+s2+s3) l[/tex]

On substituting the above values,

⇒ [tex]A = (4)(3)+(3+4+5) (9.4)[/tex]

⇒ [tex]A=12+(12)(9.4)[/tex]

⇒ [tex]A=12+112.8[/tex]

⇒ [tex]A=124.8[/tex]

Hence we can conclude that

Part A: The correct net for the prism is net A.

Part B: AB = 3 in, BC = 5 in, CD = 9.4 in.

Part C: The surface area of the prism is 124.8 square inches.

Question 3: What is the volume of corn held in this cone-shaped grain silo? 1 point
Use 3.14 for Pi and round to the nearest cubic foot (whole number). *

Nour answer I

Answers

Answer:

4,712 yards.

We can use the formula V=1/3hπr² to figure out what the volume of the cone is.

So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.

Data set = 12,14,28,28,30,30,32,32,32,32,34,34,34,36,36,36,36,36,38,38

A.) Median

B.) Median = 33

C.) Yes, Outliers: 12 and 14

D.) Skewed left

Step-by-step explanation:

Outliers: Points in the data set that are either way too small or way too big than other numbers in the data set.

Skewed: A sudden change in the data set going away from the data set:

Skewed right: If most of the data are on the left side of the histogram but a few larger values are on the right, the data are said to be skewed to the right.

Skewed left: If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.

Not Skewed: If the data are symmetric, they have about the same shape on either side of the middle.

5.The measure of smaller angle is 87 degrees.

Step-by-step explanation:

Consider the provided information.

The provided angles are 3x degree and 2x + 25 degree.

Two angles are said to be Supplementary angles if their sum is 180 degree.

It is given that the provided angle are supplementary angles, thus

3x + 2x + 25 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 31

Now, substitute the value of x in first angle i.e 3x.

3(31) = 93

Substitute the value of x in the second angle i.e 2x + 25

2(31) + 25 = 62 + 25 = 87

Hence, the measure of smaller angle is 87 degrees.

Answer:

I think the coordnates are incorrect because they do not make a pentagon when graphed. Could you please check and make sure those are right.

Step-by-step explanation:

But to do the question, you graph the points and then use the distance formula to find the side lengh of each side. Then simply just add them together. Also if you don't want to draw out a coordnate plane, you can use Desmos, an online graphing calculator.

1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle.
A. Equilateral
B. Scalene
C. Isosceles

Answers

Its Isosceles

cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles

Answer:

Isosceles

Step-by-step explanation:

An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.

Find the missing side. Round to the nearest tenth when necessary.

Answers

Answer:

15.6

Step-by-step explanation:

Because it is a right triangle, you can use the Pythagorean Theorem. The theorem is c^2 = a^2 + b^2, with c being the hypotenuse, and a and b being the legs. So plug in the values and you will get 18^2=9^2 + b^2. Solve for b and you will get 15.6.

Answer:

x=15.59

Step-by-step explanation:

using the pythagorean theorem we know a²+b²=c²

also that c²-a²=b². in this case we're using the second one. c² is 18², and a² is 9². 18²-9² is 243. we then find the square root of that number to get x (b²). x=15.59 rounded to the nearest hundreth.
