1. Round 53.2785 to the nearest tenth

Answers

Answer 1

Answer:

  53.3

Step-by-step explanation:

One way to do this is to add half a tenth, 0.05, then drop all the digits of the result to the right of the tenths digit.

  53.2785 +0.05 = 53.3285

Dropping digits to the right of the tenths place, we have ...

  53.3

_____

The effect of this is to increase the tenths digit by 1 if the hundredths digit is 5 or more. That is the usual instruction given for rounding to tenths. (Then drop hundredths and digits to the right.)

The manager of a restaurant found that the cost to produce 200 cups of coffee is ​$65.00 ​, while the cost to produce 250 cups is ​$77.50 . Assume the relationship between the cost y to produce x cups of coffee is linear. a. Write a linear equation that expresses the​ cost, y, in terms of the number of cups of​ coffee, x. b. How many cups of coffee are produced if the cost of production is ​$135.00 ​?

Answers

Answer:

a). y = 0.25x + 15

b). x = 480 cups

Step-by-step explanation:

(a). Let the equation of the linear function passing through a point (x', y') is,

y - y' = m(x - x')

'm' = slope of the line

b = y-intercept

Two points lying on the linear function will be (200, 65) and (250, 77.5).

Slope of the line 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{77.5-65}{250-200}[/tex]

   = [tex]\frac{12.5}{50}[/tex]

   = 0.25

Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,

y - 65 = 0.25(x - 200)

y - 65 = 0.25x - 50

y = 0.25x + 15

(b). For y = $135 we have to calculate the number of cups of coffee produced.

135 = 0.25x + 15

0.25x = 135 - 15

0.25x = 120

x = 480 cups

Therefore, 480 cups of coffee will be produced.

Find the distance from the point (0, 4, 3) to the plane 5x +1y +2z

Answers

Answer:

distance =

[tex] \sqrt{ \frac{10}{3} } [/tex]

Step-by-step explanation:

Without going through and deriving this (my blackboard doesn't have space and a textbook, teacher, or online tutorial is probably better for that), the equation for the distance from some point on the plane to some point in space is as follows:

[tex]distance = \frac{ax + by + cz - d }{ \sqrt{ {a}^{2} + {b}^{2} + {c}^{2} } } [/tex]

•Note that the d in the equation should actually be D but Brainly doesn't allow me to do uppercase letters on mobile it seems... Anyway, d in the equation represents the value which the equation of the plane is equal to. You only gave the plane equation so I assumed d=0 in my calculations.

•x, y, and z all come from the point which you want to find the distance to. So (x,y,z)=(0,4,3) here.

•a, b, and c all come from the components of the vector normal to the surface. For planes, it simply somes to be the coefficients in front of each part. So (a,b,c)=(5,1,2) here.

With that you just need to plug the information in and simplify for your answer. My work is in the attachment, comment with questions or if anything seems off.

How do you breakdown the quotient for 814÷3.7

Answers

Answer:

move the decimal to the end and add a zero to 814 i think

Step-by-step explanation:

Set up the division problem with the long division symbol or the long division bracket.

Put 487, the dividend, on the inside of the bracket. The dividend is the number you're dividing.
Put 32, the divisor, on the outside of the bracket. The divisor is the number you're dividing by.
step 1 divide dividend by divisor in long division 487 divided by 32 Divide the first number of the dividend, 4 by the divisor, 32.

4 divided by 32 is 0, with a remainder of 4. You can ignore the remainder for now.
step 2 subtraction in long division problem 487 divided by 32 Put the 0 on top of the division bracket.
This is the beginning of the quotient answer.

Next, multiply 0 by the divisor 32 and insert the result 0 below the first number of the dividend inside the bracket.

0 * 32 = 0
step 3 long division 487 divided by 32 Draw a line under the 0 and subtract 0 from 4.

4 - 0 = 4
step 4 long division 487 divided by 32 Bring down the next number of the dividend and insert it after the 4 so you have 48.
step 5 long division 487 divided by 32 Divide 48 by the divisor, 32. The answer is 1. You can ignore the remainder for now.

48 ÷ 32 = 1

Note that you could skip all of the previous steps with zeros and jump straight to this step. You just need to realize how many digits in the dividend you need to skip over to get your first non-zero value in the quotient answer. In this case you could divide 32 into 48 straight away.
step 6 long division 487 divided by 32 Put the 1 on top of the division bar, to the right of the 0. Next, multiply 1 by 32 and write the answer under 48.

1 * 32 = 32
step 7 long division 487 divided by 32 Draw a line and subtract 32 from 48.

48 - 32 = 16
step 8 long division 487 divided by 32 Bring down the next number from the dividend and insert it after the 16 so you have 167.
step 9 long division 487 divided by 32 Divide 167 by the 32. See a pattern emerging?

167 ÷ 32 is 5 with a remainder of 7
step 10 long division 487 divided by 32 Put the 5 on top of the division bar, to the right of the 1. Multiply 5 by 32 and write the answer under 167.

5 * 32 = 160
step 11 long division 487 divided by 32 Draw a line and subtract 160 from 167.

167 - 160 = 7
step 11 long division 487 divided by 32 Since 7 is less than 32 your long division is done. You have your answer: The quotient is 15 and the remainder is 7.

So, 487 ÷ 32 = 15 with a remainder of 7

For longer dividends, you would continue repeating the division

Questions 1, 2, and 5 are correct.

Question 3:

To find the common difference, we can subtract the last two numbers.

60 - 47 = 13

So, the common difference is 13

We can add 13 to each term to get the next term.

8 + 13 = 21

21 + 13 = 34

So, 8, 21, 34, 47, 60

Question 4:

To find the common difference, we can subtract the last two numbers.

8/3 - 2 = 2/3

So, the common difference is 2/3

We can add 2/3 to each term to get the next term.

0 + 2/3 = 2/3

2/3 + 2/3 = 4/3

So, 0, 2/3, 4/3, 2, 8/3

Question 4:

Since we are only given the first and last number, we need to find a number we can subtract that we get -13 at the end. The distance between 3 and -13 is 16. We can divide this by 4 since there are 4 numbers before -13.

16 / 4 = 4

Since the number is going down, the common difference is going to be -4.

Subtract find the next terms.

3 - 4 = -1

-1 - 4 = -5

-5 - 4 = -9

-9 - 4 = -13

So, 3, -1, -5, -9, -13

The supplement of an angle is 42 degrees less than 3 times the complement of the angle. What is the measure of the angle?

Answers

Answer: 24°

Step-by-step explanation:

Given the following :

supplement of an angle is 42 degrees less than 3 times the complement of the angle

Let the angle = θ

Supplement of angle = 180° - θ

Complement of angle = 90° - θ

Supplement of angle is also said to be:

(3 × complement) - 42° = 3(90° - θ) - 42°

= 270° - 3θ - 42° = 228° - 3θ

Hence,

180° - θ = 228° - 3θ

Solve for θ

-θ + 3θ = 228° - 180°

2θ = 48°

θ = 48°/2

θ = 24°

An isosceles triangle has vertices at (1,1) and (3, 3). Which of the following could be
the coordinates of the third vertex?
A. (2.1)
B. (3.2)
C. (4,1)
D. (5,1)
Choose

Answers

Answer:

D. (5,1)

Step-by-step explanation:

Because it is an isosceles triangle, the next point we choose must result in two sides with the same length. This means that either the two new sides are equal, or that one of the new sides is equal to the original side. If we wanted both of the new sides to be equal, they would have to be equal distance from the new point and one of the points of the original line. However, none of the options result in both new lines being the same length.

(2,1) would result in one new length being 1 unit long (2-1 x-coordinates) and the other being square root 5 (distance from point 2,1 to point 3,3 minus both coordinates and use Pythagoras). Points 3,2 and 4,1 yield the same result: Length 1=1 unit length 2=square root 5. Length 1 = 3 unit, length 2 = square root 5.

Therefore we are looking for a point which instead yields one length which is the same length as the original. The original length was 2^2 + 2^2 = c^2 = square root 8.

If we try the point 5,1 then we get two lengths of 4 and square root 8, it forms a isosceles triangle whose base line is parallel to the x-axis.

Sorry is my explanation was confusing, it's much easier to try and draw it on a grid and visualize it. Basically the overall idea is to test the side values you get by finding the distance between the points and going with the option which results in two sides with the same length.

Bill has a container that is shaped like a cube. He uses 125 cubes with a side length of 1 inch to fill the container completely. What is the edge length of the container? *****Hint: 1 inch cubes to fill a container is the volume of the cube Please answer quickly!!! Thank you.

Answers

Answer:

5 inches

Step-by-step explanation:

Given

Length of a cube = 1 inch

Required

Determine the edge length of the cube

If the container can take 125 cubes, then that's the volume

So:

[tex]Volume = 125in^3[/tex]

Volume of a cube is calculated as thus;

[tex]Volume = Length^3[/tex]

This gives;

[tex]Length^3 = 125[/tex]

Take cube root of both sides

[tex]Length = \sqrt[3]{125}[/tex]

[tex]Length = 5[/tex]

Hence, the length is 5 inches

Answers

Answer:

a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]

Step-by-step explanation:

The idea for the solution of this equation is to find the value of c where both parts of the piecewise-defined function are the same. So we need to take the parts of the function and set them equal to each other, so we get:

[tex]3-x^{2}=x[/tex]

and then solve for x. We move everything to one side of the equation so we get:

[tex]x^{2}+x-3=0[/tex]

and we use the quadratic formula:

[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

and we substitute:

[tex]x=\frac{-1\pm \sqrt{(1)^2-4(1)(-3)}}{2(1)}[/tex]

and solve

[tex]x=\frac{-1\pm \sqrt{1+12}}{2}[/tex]

[tex]x=\frac{-1\pm \sqrt{13}}{2}[/tex]

so our two answers are:

a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]

Which pair of points has a slope of 4? Question 4 options: (0, 4), (4, 0) (3, 0), (–1, –1) (1, 4), (–1, 4) (0, –3), (1, 1)

Answers

Answer:

(0,-3) and (1,1)

Step-by-step explanation:

In order to have a slope of 4, the y coordinates need to differ by 4, and the x coordinates by 1. This is because slope is equal to rise/run. Rise being difference in y value and run difference in x.

In this pair of coordinates, the y coordinates differ in +4 (-3 and 1) and the x coordinate differs by 1 (0 and 1).

Therefore this is the pair of points with a slope of 4.

Hope this helped!

The pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)

The formula for calculating the slope of a line passing through two points is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We need to get which of the coordinates will result in a slope of 4.

Using the coordinate points (0, –3), (1, 1)

[tex]m=\frac{1-(-3)}{1-0}\\m=\frac{1+3}{1}\\m=\frac{4}{1}\\m=4[/tex]

Hence the pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)

Muhammad Ali: Agent for Social ChangeA modern painting of Muhammad Ali in boxing gloves in front of an American flag.I done wrestled with an alligator, I done tussled with a whale, handcuffed lightning, thrown thunder in jail; only last week I murdered a rock, injured a stone, hospitalized a brick. Im so mean I make medicine sick. Muhammad AliMuhammad Ali was an all-time great boxer and entertainer. He was a three-time world heavyweight champion, an Olympic gold medallist, and as masterful approaching a microphone as he was in the ring. Later in life, he was made a United Nations Messenger of Peace, and awarded the United States Presidential Medal of Freedom.Hes widely celebrated today, but that wasnt always true during his boxing career. Ali was a confident, capable, Black Muslim athlete who was unafraid to speak his mind and stand up for his ideals. That made him very unpopular with a lot of people in 1960s America.Ali once said, I am America. I am the part you wont recognize. But get used to me. Black; confident; cocky; my name, not yours. My religion, not yours; my goals, my own. Get used to me.Born Cassius Clay in Louisville, Kentucky in 1942, he changed his name when he became a Muslim. He explained that Cassius Clay is a slave name. I didn't choose it and I don't want it. I am Muhammad Ali, a free nameit means beloved of God, and I insist people use it when people speak to me and of me.In 1966, Ali was at the height of his success as a boxer. At the same time, the US was fighting a war in Vietnam. The government was drafting young men to fight, which meant they had to join the Armed Forces when called. Refusing without an officially allowed reason was illegal. Ali was drafted, but refused anyway. He said he wouldnt fight in Vietnam because it was against his religion and because Black people in America were still "treated like dogs and denied simple human rights.Most Americans supported the Vietnam war at that time, and some thought Ali was a traitor. TV host David Susskind called him a disgrace to his country, his race, and what he laughingly describes as his profession. Ali was stripped of his heavyweight title, disqualified from fighting, and given a $10,000 fine and a prison sentence. But to many, he was a hero. Civil rights leader Reverend Al Sharpton said, he knew he was going to jail and did it anyway. That's another level of leadership and sacrifice.By resisting injustice and inequality, and by never apologizing for who he was, Muhammad Ali inspired countless peopleespecially Black Americans and athletes. Basketball legend Kareem Abdul-Jabbar said, Ali's impact on young people was very formidable . . . The fact that he was proud to be a Black man, and that he had so much talent . . . made certain people love him and made other people think that he was dangerous. But, for those very reasons, that's why I enjoyed him.Ali returned to boxing in 1971 and won back his heavyweight title in 1974.
