Answers

Answer:

1/8 m³

Step-by-step explanation:

Given that:

Side length of block, s = 1/4

Volume of block, V

V = s³

Volume of block = (1/4)³ = 1/4 * 1/4 * 1/4 = 1 /64

The rectangular prism takes 8 of this blocks :

Hence, the volume of the rectangular prism is :

Number of blocks * Volume per block

8 * 1 /64

8 /64

= 1/8 m³

B. T=winning time in the man's 100 meter dash at the 2016 Olympics

C. P=number of points scored by Stephen curry in a game

D.H=The number of hats sold on Tuesday

Answers

I assume it’s A because there will always be incoming flights at a local airport whereas the other options are limited and can’t be changed

Answer:

option A

Step-by-step explanation:

because it is not limited to anything while option b is limited to the men's hundred meter dash and 2016, and to the Olympics

C is limited to one game and stephen curry

D is limited to tuesday

since option a isn't confined to one day, person, or specific event there can be endless numbers assigned to the variable

Answer: 11 - (-12) = 23

              -22 - 49 = -71

Answer:

23

-71

Step-by-step explanation:

11 - (-12) = ?

-22 - 49 = ?

11 - ( -12) = 11 + 12 = 23

-22 - 49

subtracting a negative from a negative is like adding a positive to a positive it has the same affect just a different sign

-22 - 49 = -(22 + 49)

22 + 49 = 71

-(71) = -71

Answer:

m<ADC = 107

Step-by-step explanation:

You need to know three things to solve this problem.

1) Opposite angles of an inscribed quadrilateral are supplementary.

2) The measure of an inscribed angle is half the measure of its subtended arc.

3) The sum of the measures of all the arcs of a circle is 360 deg.

From 1) we get:

m<A + m<C = 180

72 + m<C = 180

m<C = 108

From 2) we get:

m<C = (1/2)m(arc)BAD

108 = (1/2)[m(arc)AB + m(arc)AD]

216 = m(arc)AB + 122

m(arc)AB = 94

From 3) we get:

m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360

94 + 120 + m(arc)CD + 122 = 360

m(arc)CD = 24

From 2) we get:

m<ADC = (1/2)m(arc)ABC

m<ADC = (1/2)[m(arc)AB + m(arc)BC]

m<ADC = (1/2)[94 + 120]

m<ADC = 107

Find the output, ddd, when the input, ttt, is 111111. d =-20+11td=−20+11td, equals, minus, 20, plus, 11, t d=d=d, equals

Answers

Answer:

d=101

Step-by-step explanation:

If 11 is being multiplied by t, and t is 11, we multiply 11 by 11, we get 121.

After adding that to our equation, we get -20 + 121, which equals 101.

Therefore d=101

The value of d, when t = 11 is equal to 141.

What is a function?

An expression in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is the following equation -

d = - 20 + 11t

We have -

d = - 20 + 11t

for t = 11, we get -

d = 20 + 11 x 11

d = 20 + 121

d = 141

Therefore, the value of d, when t = 11 is equal to 141.

Answers

Answer:

Step-by-step explanation:

Sum the parts of the ratio, 2 + 3 + 5 = 10 parts

Divide the profit by 10 to find the value of one part of the ratio.

$450 000 ÷ 10 = $45 000 ← value of 1 part of the ratio, then

2 parts = 2 × $45 000 = $90 000 ← Lea's share

3 parts = 3 × $45 000 = $135 000 ← Paul's share

5 parts = 5 × $45 000 = $225 000 ← Tynos' share

Step-by-step explanation:

Volume for triangular prism = 1/2 * b * l * h

we are given the length and the height but not the base.

since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2

13.3^2 + b^2 = 20.5^2

176.89 + b^2 = 420.25

b^2 = 243.36

b = [tex]\sqrt{243.36}[/tex] = 15.6

1/2 (15.6)(13.3)(16) = 1659.84

Front: 15.6 x 13.3 = 207.48

Back: 15.6 x 13.3 = 207.48

Left: 15.6 x 16 = 249.6

Right: 13.3 x 16 = 212.8

Bottom: 20.5 x 16 = 328

207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

2/3pi x r^3 = 257

Divide both sides by 2/3pi

r^3 = 122.708

Cube root both sides.

r = 11.077

Use algebra, so

2m + 3s = 64 and also

4m + 2s = 72

Multiply the top equation by 2 so both have 4m, so

4m + 6s = 128 and also

4m + 2s = 72

Then minus the numbers form the top equation by the bottom equation, so

4m + 6s = 128

- - -

4m + 2s = 72

This gives you 4s=56 so divide by 4 so s=14

No put 14 into the equation for s and rearrange to solve for m, so

2m+3s=64 So

2m+3x14=64

2m+42=64

Then minus 42

2m=22

m=11

What can you do to make it a good day?Write a paragraph to answer the prompt. excerpt from Address at Rice University on the Nation's Space Effort by John F. KennedyJohn F. Kennedy became president in 1961 at a time when there were serious tensions between the United States and the Soviet Union; each country strove to surpass the other in military, political, and economic power. When Kennedy took office, the public perception was that the Soviet Union had established itself as leader in the space race, a term coined to represent the competition between the two super powers for dominance in development of space technologies and exploration. In this speech, delivered at Rice University in Texas, Kennedy describes his goals for space exploration, which included landing a man on the moon.1 Those who came before us made certain that this country rode the first waves of the industrial revolution, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of itwe mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.2 Yet the vows of this Nation can only be fulfilled if we in this Nation are first, and, therefore, we intend to be first. In short, our leadership in science and industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to make this effort, to solve these mysteries, to solve them for the good of all men, and to become the worlds leading space-faring nation.3 We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.4 We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.5 It is for these reasons that I regard the decision last year to shift our efforts in space from low to high gear as among the most important decisions that will be made during my incumbency in the office of the Presidency.6 In the last 24 hours we have seen facilities now being created for the greatest and most complex exploration in mans history. We have felt the ground shake and the air shattered by the testing of a Saturn C-1 booster rocket, many times as powerful as the Atlas which launched John Glenn, generating power equivalent to 10,000 automobiles with their accelerators on the floor. We have seen the site where five F-1 rocket engines, each one as powerful as all eight engines of the Saturn combined, will be clustered together to make the advanced Saturn missile, assembled in a new building to be built at Cape Canaveral as tall as a 48 story structure, as wide as a city block, and as long as two lengths of this field.----------Which paragraph from the text most effectively develops Kennedys theme that anything is possible if people are willing to invest the effort to make it happen?Paragraph 1Paragraph 3Paragraph 4Paragraph 6 2/6+1/4Show work pleaseAnd no links Do you agree or disagree with Bidens views on unions?
