Answer:

Sean didn't finish the job. He painted 23/30 of the fence in two hours.

Step-by-step explanation

He didn't finish the job because 23/30 is not finished. It isn't finished because Sean is less than 23/30 of the way done. That doesn't seem done to me.

I got the fraction 23/30 by looking at the problem carefully. He painted 3/10 of the fence "less" than the first hour which was 8/15 of the fence. So that means we have to subtract 8/15 and 3/10 to get 7/30.

Now, we just figured out how much Sean painted in the second hour, and the question is asking what fraction of the fence did he paint in BOTH hours. Meaning we have to add the first and second hour to get the answer of 23/30.

                                Hope this helped! Have a great day!

No, he did not finish his job.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given, Sean paints 8/15 of a fence in 1 hour,

Sean paints 3/10 part less in the second hour So, fraction he paints in the second hour = 8/15-3/10 = 16-9/30 = 7/30

So,

Paint in 2 hours = 8/15+7/30 = 16+7 / 30 = 23/30

Hence, he did not finish his job.

Answer:

(8x - 9)˚ = 63˚

and

(3x)˚ = 27˚

Step-by-step explanation:

heeyyyyy remember me?

Complementary angles are angles that equal 90˚, so we can create an equation:

(8x - 9) + 3x = 90

Remove the paranthesis

8x - 9 + 3x = 90

Add 9 to both sides

8x + 3x = 99

Simplify

11x = 99

divide both sides by 11

x = 9

So if we plug in x for 9 we get:

8x - 9

8(9) - 9

72 - 9

63

3x

3(9)

27

So

(8x - 9)˚ = 63˚

and

(3x)˚ = 27˚

Answer:

I have 2

1)working for 2 hours and getting payed $55

2)you have $-55 in your bank

Step-by-step explanation:

The required integer that represents paying a bill of $55 would be "55".

Integers are defined as the collection of Whole Numbers  Integers is represented by the symbol Z.

Integers are numbers that can be written without a fractional or decimal component, such as -3, -2, -1, 0, 1, 2, 3, and so on. They include the positive whole numbers (1, 2, 3, etc.), the negative whole numbers (-1, -2, -3, etc.), and zero.

We have to write an integer to represent the given situation.

As per the question, the integer represents the amount of money being paid in dollars.

Therefore, an integer that represents paying a bill of $55 would be "55".

Answer:

(-4,-10) and (5,-3)

Step-by-step explanation:

To be honest, this kind of question allows for any coordinates as long as they have the slope of 9/7.

I know the slope equation is (y2-y1)/(x2-x1) = m (where m is slope)

(y2-y1)/(x2-x1) = 9/7

From this equation, find any two numbers that have a difference of 9 to the y-coordinates.

I'll go with 5 and -4 (y-coordinates)

And two integers that have a difference of 7 for the x-coordinates.

I go with -3 and -10 (x- coordinates)

So the points I got are,

(5-(-4))/((-3)-(-10)) = 9/7

5-(-4) is equal to 5+4 (2 minus signs are equal to 1 plus sign), which is 9.

(-3)-(-10) is equal to -3+10 (2 minus signs are equal to 1 plus sign), which is 7.

The two points are (-4,-10) and (5,-3)

Notice if we were to subtract 5 from -4, we would also have to subtract -3 from -10.

-4-5= -9 and -10- -3 = -10+3 = -7

-9/-7 is the same as 9/7.

Basically, (-4,-10) and (5,-3) are different coordinates and you can only switch them as coordinate 1 or 2 but not the points.

Sorry, took a while, hope I was able to help! Good Luck.

Answer:

6.75>6.732

Step-by-step explanation:

We are given that

6.75 and 6.732

We have to compare two given decimal numbers.

First we convert like decimal number

In 6.75 there are two digits after decimal point.

In 6.732 , there are three digits after decimal point

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get

6.750

Unit place of both decimal numbers are same and tenth place of both decimal number are same.

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3

5 >3

Therefore, 6.750 is greater than 6.732

6.75>6.732

Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance

There is a difference between the means

Step-by-step explanation:

Step(i):-

Given that mean of the Population = 5.9pounds/square inch

Given mean of the sample = 6.0pounds/square inch

Given that variance of the Population = 0.36

The standard deviation of the Population = √0.36 =0.6

critical value (Z₀.₀₅)= 1.96

Step(ii):-

Null Hypothesis:H₀: x⁻ = μ

Alternative Hypothesis:H₁:  x⁻ ≠ μ

Test statistic

              [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

               [tex]Z = \frac{6.0-5.9 }{\frac{0.6}{\sqrt{160} } }[/tex]

              Z  =  2.1097

Final answer:-

Calculated value Z = 2.1097 > 1.96 at 0.05 level of significance

The null hypothesis is rejected

There is a difference between the means

Answer:

y = -4x + 17

Step-by-step explanation:

Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.
