Answer:

It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2,  think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.

a) Work out the value of 5^2 – 1^5× 2^4
b) Work out the value of 7^2 + 4^3 ÷ 2^5​

Answers

First you have to know BODMAS/BIDMAS (idk if all schools teach it like this) but this is the order in which you complete questions so it’s Brackets, Indices, Division/Multiplication, Addition/Subtraction
a) 5^2 is 5x5 which equals 25 1 to the power of anything is always 1 and 2^4 is 2x2x2x2 which is 16
So 5^2-1^5x2^4 = 25-1x16 which is then 25-16 = 9
b) 7^2+4^3 divided by 2^5 so 7^2 is 7x7 which = 49 then 4^3 means 4x4x4 = 64 and 2^5 is 2x2x2x2x2 which equals 32 so
7^2+4^3 divides by 2^5 is 49+64/32 = 49+2 which is 51

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers

Answers

Answer: t 0<t<3

Step-by-step explanation:

Answer:

The correct option is 1.

Step-by-step explanation:

The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.

The value of height and time can not be negative, there the values of h and t must be greater than 0.

The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.

The graph is defined from t=0 to t=3.

Therefore option 1 is correct.

- If JL = 5x + 2, find JL.

Answers

Answer:

JL= 62

Step-by-step explanation:

27+3x-1=5x+2

3x+26=5x+2

3x+24=5x

24=2x

12=x

now plug in x(which is 12) for JL

5(12)+2

60+2

=62

The measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

JL = 5x + 2

From the line segment:

JL = 27 + 3x - 1

Plug the value of JL in the equation:

5x + 2  = 27 + 3x - 1

After solving:

5x - 3x = 26 - 2

2x = 24

x = 12

JL = 5x + 2

Plug x = 12 in the above equation:

JL = 5(12) + 2

JL = 60 + 2

JL = 62 units

Thus, the measure of the line segment is 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

What is LaTeX: m\angle PTQm ∠ P T Q?

Group of answer choices

140

40

50

12

Answers

Answer:

B. 40

Step-by-step explanation:

If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)

Given

PTQ is x + 28

RTS is 2x + 16

Since they are both equal, then x+28 = 2x+16

collect like terms

x-2x = 16-28

-x = -12

multiply both sides by -1

-1(-x) = -1(-12)

x = 12

Since ∠ P T Q = x+28, substitute x = 12 into the function

∠ P T Q = 12+28

∠ P T Q = 40

Hence measure of ∠ P T Q is 40°

Its astounding to me, for example, that so many people really appear to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldnt stay there any longer and had to go someplace else to make it. Thats all. They were hungry, they were poor, they were convicts. Those who were making it in England, for example, did not get on the Mayflower. Thats how the country was settled. Not by Gary Cooper. Yet we have a whole race of people, a whole republic, who believe the myths to the point where even today they select political representatives, as far as I can tell, by how closely they resemble Gary Cooper. Now this is dangerously infantile, and it shows in every level of national life. When I was living in Europe, for example, one of the worst revelations to me was the way Americans walked around Europe buying this and buying that and insulting everybodynot even out of malice, just because they didnt know any better. Well, that is the way they have always treated me. They werent cruel; they just didnt know you were alive. They didnt know you had any feelings. What I am trying to suggest here is that in the doing of all this for 100 years or more, it is the American white man who has long since lost his grip on reality. In some peculiar way, having created this myth about Negroes, and the myth about his own history, he created myths about the world so that, for example, he was astounded that some people could prefer Castro, astounded that there are people in the world who dont go into hiding when they hear the word Communism, astounded that Communism is one of the realities of the twentieth century which we will not overcome by pretending that it does not exist. The political level in this country now, on the part of people who should know better, is abysmal. The Bible says somewhere that where there is no vision the people perish. I dont think anyone can doubt that in this country today we are menacedintolerably menacedby a lack of vision. It is inconceivable that a sovereign people should continue, as we do so abjectly, to say, I cant do anything about it. Its the government. The government is the creation of the people. It is responsible to the people. And the people are responsible for it. No American has the right to allow the present government to say, when Negro children are being bombed and hosed and shot and beaten all over the Deep South, that there is nothing we can do about it. There must have been a day in this countrys life when the bombing of the children in Sunday School would have created a public uproar and endangered the life of a Governor Wallace. It happened here and there was no public uproar. What is Baldwins purpose in using dialogue in paragraph 4?
