i don’t need a explanation i just need a answer pls hurry!!

Answers

Answer:

6,656 square meters

Step-by-step explanation:

Surface area of triangular pyramid = bh + L(S1 + S2 + S3)

Where,

b = 48 m

h = 32 m

L = 40 m

S1 = 40 m

S2 = 40 m

S3 = 48 m

Plug in the values

Surface area = 48*32 + 40(40 + 40 + 48)

= 1,536 + 5,120

= 6,656 m²

The perimeter
particular rectangle is
36 centimeters. The longer sides of the rectangle are
cach 2 centimeters longer than each of the shorter sides
of the rectangle. What is the length, in centimeters, of
one of the longer sides of this rectangle"?

Answers

Answer:

Long side of the rectangle: 11cm

Shorter side of the rectangle: 7cm

Step-by-step explanation:

36cm divided by 4 = 9

9-2=7

take that two and add it to the other two nines

9+2=11

The required length of the longer sides of rectangle is 10cm.

The perimeter of the rectangle is 36 centimeters,
length = 2+ width

What is rectangle?

rectangle is four sided polygon whose opposites sides are equal and has angle of 90° between its sides.

Perimeter = 2 length x 2 width
36 = 2(2+width) x 2width
36= 4 (1+width)
width = 8
length= 2+width
length = 2+ 8
length = 10 centimeters

Thus, The required length of the longer sides of rectangle is 10cm.

What is the approximate length of the base of the parallelogram in the diagram?

Answers

Answer:

2piR

Step-by-step explanation:

The base of the parallelogram is equal to the circumference.

The length of the base of the parallelogram will be πr.

What is Parallelogram? What is triangle? What is a expression? What is a mathematical equation?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.

We have a circle converted into a parallelogram as shown.

The angle subtended by each arc at the center =

Ф = (360°/8) = 45°

Length of each arc will be -

L = (Ф/360°) x 2πr

L = (45/360) x 2πr

L = (5/40) x 2πr

L = 1/8 x 2πr

L(A) = πr/4

Length of the base will be -

L(B) = 4 x L(A) = 4 x πr/4 = πr

Therefore, the length of the base of the parallelogram will be πr.

The estimated regression equation by least squares method minimizes the sum of the Group of answer choices Absolute deviations between actual and predicted y values Differences between actual and predicted y values. Squared differences between actual and predicted y values None of the choices Absolute deviations between actual and predicted x values.

Answers

Answer:

Squared differences between actual and predicted y

Step-by-step explanation:

The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.

The true statement is that the estimated regression equation by least squares method minimizes the sum of the (c) Squared differences between actual and predicted y.

In regression, the least square method is used to estimate quantities.

This is done in order to minimize the sum of the squares of the differences between the observed values and the estimated values.

In this case, the observed value and the estimated values represent the actual and predicted y

Hence, the true statement is that the estimated regression equation by least squares method minimizes the sum of the (c)

Step-by-step explanation:

2[(8*6)+(6*12)+(12*8)]

To find surface area you need to find the area of each side on the shape then add it all together. So for the triangle you need to do 1/2 BxH then multiply the number by 2 because you have 2 triangles. Next you can work out the base LxW then to work out the side you do HxL. Your basically just working out the total area of each side that’s possible to touch, every single side.

One rectangular solid with a square base has twice the height of another rectangular solid with a square base with the same side length. Which statements about the two rectangular solids are true?
Check all that apply.

The bases are congruent.

The solids are similar.

The ratio of the volumes of the first solid to the second solid is 8:1.

The volume of the first solid is twice as much as the volume of the second solid.

If the dimensions of the second solid are x by x by h, the first solid has 4xh more surface area than the second solid.

Answers

Answer:

First rectangular solid and second Rectangular solid

1. Bases are in the form of square having same dimensions

2. Height of first rectangular solid=2 ×Height of second rectangular solid

The true statements are

A) The bases are congruent.→The meaning of term congruent is that , the two bases are in the shape of square having same dimensions.

(B) No, The solids are not similar.as ratio of side lengths in not same in each case , because the ratio of heights of two solid is equal to .

(D) Volume of first solid = x *x*2 H=2 x²H

Volume of second solid = x*x*H=x²H

Ratio of volumes =2:1

So, option (D) is true.

(E) Surface area of first solid =2[x*x+x*2 H+2 H*x]

=2[x²+4 H*x]=2 *x*[x+4* H]

Surface area of second solid = 2[x*x+x* H+ H*x]=2[x²+2 H*x]=2* x*[x+ 2*H]

The Cold War was the ideological, political, and economic conflict between the United States and the Soviet Union following World War II. During the Cold War, each country tried to limit the other country's influence around the world by building nuclear weapons, supplying weapons and money to other countries to gain their support, and spreading false information about the other. While the two countries never came into direct, open conflict with each other, they did come into indirect conflict numerous times. This included the Cuban Missile Crisis, when the world seemed on the edge of a nuclear war.A historian has made the claim that too much is being made of the Cold War and that it was never a significant threat to world peace, as proven by the fact that the United States and the Soviet Union never went to war. Read these excerpts from speeches given by Nikita Khrushchev, Fidel Castro, and John F. Kennedy during the Cold War. Use the information from the three passages to write a historical essay that responds to the historian's claim. Be sure to include an introduction paragraph with a thesis, body paragraphs with at least three pieces of evidence supporting your thesis, a counterclaim to your thesis, and a refutation of that counterclaim. Finally, include a conclusion paragraph restating your thesis and the evidence supporting it. Passage 1: Soviet premier Nikita Khrushchev addressed the UN Assembly in 1960 after U.S. military aircraft allegedly entered Soviet airspace.We saw a dangerous manifestation of the work of these forces last spring when the aircraft of one of the largest States Members of the United Nations, the United States of America, treacherously invaded the air space of the Soviet Union and that of other States. What is more, the United States has elevated such violations of international law into a principle of deliberate State policy. The aggressive intrusion into our country by a United States aircraft and the whole course of the United States Government's subsequent behaviour showed the peoples that they were dealing with a calculated policy on the part of the United States Government, which was trying to substitute brigandage for international law and treachery for honest negotiations between sovereign and equal States.3Passage 2: Cuban prime minister Fidel Castro made a speech in 1961 after the United States sponsored the failed Bay of Pigs invasion of Cuba, a Soviet ally.Our position is that we will fight to the last man, but we do not want direct aggression. We do not wish to suffer the destruction that aggression would bring. If the aggression comes, it will meet the total resistance of our people.. . . They are the ones who are bringing the world to the brink of war through their warlike spirit, their own contradictions, and their economic problems which cause them to provoke a series of crises in order to maintain their war economy. Their factories run only when they are building war material. Their regime is marching toward a crisis. It is not like our economy, which is perfectly planned.4Passage 3: U.S. president John F. Kennedy addressed the United States after it was discovered that the Soviet Union had placed nuclear weapons in Cuba, just 70 miles from the U.S. border. I want to take this opportunity to report on the conclusions which this Government has reached on the basis of yesterday's aerial photographs which will be made available tomorrow, as well as other indications, namely, that the Soviet missile bases in Cuba are being dismantled, their missiles and related equipment are being crated, and the fixed installations at these sites are being destroyed.
