An angle measures 143.4° less than the measure of a supplementary angle. What is the measure of each angle?

Answers

Given :-

Measure of an angle = x

Measure of another angle = x - 143.4

Each angle is the supplement of the other angle .

Which means :-

[tex]x + x - 143.4= 180[/tex]

[tex]2x - 143.4 = 180[/tex]

[tex]2x = 180 + 143.4[/tex]

[tex]2x = 323.4[/tex]

[tex]x = \frac{323.4}{2} [/tex]

[tex]\color{hotpink}x = 161.7[/tex]

Then :-

Measure of the first angle :-

[tex]\color{hotpink} = 161.7°[/tex]

Measure of the second angle :-

[tex] = x - 143.4[/tex]

[tex] = 16.7 - 143.4[/tex]

[tex]\color{hotpink} = 18.3°[/tex]

As the sum of the measure of each angle adds up to 180° (161.7+18.3=180) , we can conclude that we have found out the correct value of each of the angles .

Therefore , the measure of the first angle is = 161.7° and the measure of it's supplementary angle is = 18.3° .

In Mr. Britt's class the distribution of ages of his students has a mean of 115 months and a standard
deviation of 3.6 months.

If no students leave or join the class, what will be the mean and standard deviation of the distribution of
student's ages 4 months later?

Answers

Using statistical concepts, it is found that the mean will be of 119 months, while the standard deviation will be of 3.6 months, given by option C.

-------------------------------------

The mean of a data-set is the sum of all values divided by the number of values.The standard deviation is the square root of the sum of the difference squared of each observation and the mean, divided by the number of values.If x is added to all values of a data-set, it is also added to the mean, while the standard deviation remains constant.

-------------------------------------

Mean of 115 months and standard deviation of 3.6 months.4 months later is the same as adding 4 to each observation.Thus, the mean will be of 115 + 4 = 119 months, while the standard deviation remains constant at 3.6 months.

Graph the line with slope of 4/3
and goes through the point (1,3)

ANSWER THIS FAST!

Answers

Answer:

Step-by-step explanation:

y=4/3 x +b

goes through the point (1,3)

3=4/3(1)+b

b=3-4/3

b=9-4/3

b=5/3

equation : y=4/3 x +5/3

The graph of the line with slope of 4/3 and goes through the point (1,3) is shown in attached figure.

What is Equation of line?

The equation of line with slope m and passes through the point (x₁, y₁) is given as;

y - y₁ = m (x - x₁)

Given that;

The slope of line = 4/3

And, Point on line = (1, 3)

Since, The equation of line with slope m and passes through the point (x₁, y₁) is given as;

y - y₁ = m (x - x₁)

Thus, The equation of line with slope 4/3 and passes through the point (1, 3) is given as;

y - 3 = 4/3 (x - 1)

Solve as;

3 (y - 3) = 4 (x - 1)

3y - 9 = 4x - 4

3y = 4x - 4 + 9

3y = 4x + 5

y = 4/3x + 5/3

Thus, The equation of line will be;

y = 4/3x + 5/3

So, The graph of the line y = 4/3x + 5/3 is shown in attached figure.

On Monday morning Sergio Pappas had $14.78 in cash.

and $22.12 on gas.
# Problem Solution
a. What were Sergio's total earnings for the week?
b. What total amount did he have to spend during the week?
c. What was his balance at the end of the week?

( please do not comment if you do not know the answer, would be appreciated )

Answers

Answer:

Step-by-step explanation:

a-As he had earned $45.00 for cutting lawns and had earned $35.75 for yard work during the week and had not earned more than that, in order to find the total amount of money he earned during the week, we have to add $45.00 and $35.75 together which will be $80.75. So we can say that he had earned $80.75 during the week.

b- Since he had spent $25.23 on food and $22.12 on gas, we have to add them to get the total amount of money spend during the week. So after adding the amount of moneys spent, we will get $47.35.

c- Finally, to find out how many money he was left with, we have to subtract the amount of moneys spent from the total amount of earnings for the week. So, after subtracting $47.35 from $80.75 he is left with $33.4.

Which two excerpts appear toward the end of the plot structure of Jack London's "Up the Slide"? But the descent was precipitate and dangerous in the uncertain moonlight, and he elected to go down the mountain by its gentler northern flank. In a couple of hours he reached the Yukon at the Siwash village, and took the river-trail back to where he had left the dogs. There he found Swanson, with a fire going, waiting for him to come down. Halting his dogs beneath, on the river ice, he looked up, and after some searching, rediscovered it. Being dead, its weatherbeaten gray so blended with the gray wall of rock that a thousand men could pass by and never notice it. Taking root in a cranny, it had grown up, exhausted its bit of soil, and perished. Beneath it the wall fell sheer for a hundred feet to the river. It stood to reason, Swanson said, that good, dry firewood could not be found so close to Dawson; that whatever firewood there was originally had long since been gathered in; that firewood would not be selling at forty dollars a cord if any man could go out and get a sled-load and be back in the time Clay expected to make it. Clay ran his experienced eye over the timber, and estimated that it would chop up into fifty cords at least. Beyond, the gully closed in and became barren rock again. On every hand was barren rock, so the wonder was small that the trees had escaped the eyes of men. They were only to be discovered as he had discovered them by climbing after them. He sat down and looked at the treacherous snow-covered slope. It was manifestly impossible for him to make it with a whole body, and he did not wish to arrive at the bottom shattered like the pine tree. This figure has two intersecting lines and a ray.
