Answer 2

After 1 hour, Yao had completed 25% (1/4) of the 2-hour Mathematics paper.

In order to understand the fraction of time Yao had spent on the Mathematics paper after 1 hour, let's break down the problem. Yao was given a 2-hour Mathematics paper to complete, and he answered 5 questions in the first hour.

Now, let's calculate the fraction of time that had passed. To do this, we can set up a ratio of the time Yao had spent to the total time available. The time Yao spent is 1 hour, and the total time available is 2 hours. So the fraction of time that had gone can be represented as:

= Time spent / Total time

= 1 hour / 2 hours

= 1/2

Therefore, after 1 hour, Yao had completed half of the allotted time. However, we are asked to express this fraction in terms of questions answered. Yao had answered 5 questions out of a total of 20 questions.

To express the fraction of time in terms of questions answered, we can set up another ratio. The questions Yao answered is 5, and the total number of questions is 20. So the fraction of time that had gone can be represented as:

= Questions answered / Total questions

= 5 questions / 20 questions

= 1/4

Hence, after 1 hour, Yao had completed 1/4 of the total questions in the Mathematics paper. This means he still had 3/4 (or 75%) of the questions to complete in the remaining hour.

5(w + 4 x 10^3)= 6 x 10^4

Answers

Answer:

w = 8000

Step-by-step explanation:

5(w+4*10^3) = 6(10^4)

5(w+4*1000) = 6(10000)

5(w+4000) = 60000

Answer:  y=5

Step-by-step explanation:

The line only has a value of 5, regardless of the value of x.  So the slope of this line is "o," the vlaue of x has no influence on the value of y.

y = mx + b

y = ox + b

b is the y-intercept, the value of y when x = 0.  That would be 5, again:

y = 0x + b

y = b

y = 5

It it’s y=5

Explanation:
Because on a linear graph the equation is y=x so with this specific graph the line goes horizontally on (5,0) so applying that to the equation its y=5

Answer:

[tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

By subtracting x³ - 3x² + x - 1 , that is

[tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - (x³ - 3x² + x - 1) ← distribute by - 1

= [tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - x³ + 3x² - x + 1 ← collect like terms

= [tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

x⁴ + 5x³ - 6x² - 5x - 2

should become

x³ - 3x² + x -1

so, what do I need to subtract from the top terms to get the bottom terms ?

because we can only look from one x- term to the next. we can only combine them, when they have the same x exponent.

so, we see there is no x⁴ in the desired result.

therefore, we know as a first item that x⁴ had to be subtracted.

the next x exponent is 3.

we have 5x³ on the top, and x³ on the bottom.

so, clearly, we need to subtract 4x³ as second term.

the next x exponent is 2.

we have -6x² on the top, and -3x² on the bottom.

so, we should actually add 3x². and how do we do this in a subtraction ? by subtracting a negative value, which actual adds it.

so, we need to subtract -3x² as third term.

the next x exponent is 1 (just x).

we have -5x on the top and x on the bottom.

so, the same trick as before, as we need to add something.

so, we need to subtract -6x as fourth term.

and finally, the x exponent 0, which just shows the constant numbers.

we have -2 on the top and -1 on the bottom.

again the same trick to actually add 1.

we need to subtract -1 as fifth term.

so, in total, this is what we need to subtract from the top line to get the bottom line :

x⁴ + 4x³ - 3x² - 6x - 1

Find the value of x and y

Answers

Answer:

x = 10 and y = 15

Step-by-step explanation:

The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD

5x - 20° = x + 20°

4x = 40°

x = 10°, which gives us the first answer.

The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:

angle ACE = angle ACB + x + 20° + y + 20° = 180°

angle ACB + x + y + 40° = 180°

angle ACB = -x - y + 140°

Inserting the x we found earlier this gives

∠ACB = - y + 130°

Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:

4y - 25° + 5x - 20° + ∠ACB = 180°

Substituting x again gives

4y - 25° + 50° - 20° + ACB = 180°

ACB = 180 - 4y - 5° = 175° -4y

Combining the two expressions for ACB gives the final equation to solve:

175° - 4y = -y + 130°

-3y = -45

y = 15

if you make $391 for 17 hours how much would you make in 13 hours

Answers

To find the unit rate, 391/17 gives us 23$ per hour time 13 hours is 299$ total.

Answer:

We would make $299 in 13 hours.

Step-by-step explanation:

Hi there!

We're given:

⇒ We make $391 in 17 hours

To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:

391 ÷ 17 = 23

Therefore, we make $23 in 1 hour.

Multiply $23 by 13 hours to find how much we would make in 13 hours:

23 × 13 = 299

Therefore, we would make $299 in 13 hours.

Answer:

7cm

Step-by-step explanation:

One side of a square is increased by 8 cm, let us say the length got increased by 8 cm. So we have length of x + 8 cm

An adjacent side, the width, decreased by 2 cm. So we have width of x - 2cm

Perimeter of rectangle = 2(length + width)

40 = 2( (x + 8) + ( x - 2) )

40 = 2( 2x + 6)

40 = 4x + 12

28 = 4x

x = 7 cm

That is 7 cm of the length of the side of the square
