Step-by-step explanation:

Answer:

[tex]z=133/6[/tex]

Step-by-step explanation:

All angles in a triangle added up are equal to 180 degrees.

We can make the equation:

[tex]2z+4z+47=180\\6z+47=180\\6z=133\\z=133/6[/tex]

Answer:

Step-by-step explanation:

We have 3 angles, 2z, 4z, 42

the sum of these angles equal to 180

2z+4z+42=180

6z=180-42

6z=138

z=138/6=23

z=23

Answer:

y = x + 8

Step-by-step explanation:

Answer:

To determine if a point is on a line you can simply subsitute the x and y coordinates into the equation. Another way to solve the problem would be to graph the line and see if it falls on the line. Plugging in will give which is a true statement, so it is on the line.

Answer:

A)  [tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]

B) 20 x + 500 y

Step-by-step explanation:

A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.  

A = The square of the sum of a and b is  [tex](a+b)^{2}[/tex]

B = The cube root of the product of x and 3y is  [tex]\sqrt[3]{x . 3y}[/tex]

They want us to subtract B from A so B - A, therefore the following.

[tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]

B. The total value of x 20-cent coins and y 5-dollar notes in cents.

20x cents is already provided as they want the expression in cents. Moving on to the $5 dollar note. We will have to convert this $5 into cents in order to fulfill the question requirements.

Convert:

1 dollar = 100 cents

5 dollars = 100x5 = 500 cents

Therefore, 5y dollars = 500y cents. Finally, we end up with the following answer.

20 x cents + 500 y cents

20 x + 500 y

Answer:

Maths = 120

English = 84

Hindi = 63

Step-by-step explanation:

First, solve for Maths since the others require that answer.

Using decimals, 80% of 150 can be written as 0.8 x 150 = x (where x is 80% of 150).

0.8 x 150 = x

120 = x

Since you know the score for maths, you can find the score for english, which is 70% of 120.

0.7 x 120 = y

84 = y

Since you now have the score for English too, that can be used to find the score for Hindi, which is 75% of the English score (84)

0.75 x 84 = z

63 = z

Answer:

B (-2, 4)

C (-1, 0)

Step-by-step explanation:

(x,y) -> (x - 8, y - 2)

A (2, 3) -> (2 - 8, 3 - 2) = A (-6, 1)

B (6, 6) -> (6 - 8, 6 - 2) = B (-2, 4)

C (7, 2) -> (7 - 8, 2 - 2) = C (-1, 0)

Hope this helped and made sense!

Step-by-step explanation:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

Answer:

5x-10

Step-by-step explanation:

Answer:

5x-10

Step-by-step explanation:

You can add the x together, 2+3 is 5 so we have 5x.

The you add the other numbers, -8+-2 is -10.

You then can put the addition in, and have 5x+-10. Since 10 is a negative, there's no need to put the addition sign, so 5x-10 would be the answer.

Answer:

66 coolers

Step-by-step explanation:

C = 0.005x² - 0.3x + 17

When C = $19

19 = 0.005x² - 0.3x + 17

19 - 17 = 0.005x² - 0.3x

2 = 0.005x² - 0.3x

0.005x² - 0.3x - 2 = 0

x = -b ± √b² - 4ac / 2a

= -(-0.3) ± √-0.3² - 4*0.005*-2 / 2*0.005

= 0.3 ± √ 0.09 - (-0.04) / 0.01

= 0.3 ± √ 0.09 + 0.04 / 0.01

= 0.3 ± √ 0.13 / 0.01

= 0.3/0.01 ± √0.13/0.01

= 30 ± 0.36/0.01

x = 30 ± 36

x = 30 + 36 or 30 - 36

x = 66 or -6

Number of coolers can not be negative

Therefore, number of coolers produced when the cost is $19

is 66 coolers

Answer:

Step-by-step explanation:

(0,3)  (3, 5)

(5-3)/(3-0)= 2/3

y - 3 = 2/3(x - 0)

y - 3 = 2/3x - 0

y = 2/3x + 3

Answer:

The car travelled an average speed of 80 km/h.

Step-by-step explanation:

Distance travelled by the car = 160 km

Time taken by the car = 2 hours.

Average speed =?

Average speed = Distance/Time

Average speed = 160/2

Average speed = 80 km/h

The car travelled an average speed of 80 km/h.

Answer:

[tex]12\pi in[/tex]

Step-by-step explanation:

We are given that

Area of circle=[tex]36\pi in^2[/tex]

We have to find the circumference of circle in inches.

We know that

Area of circle=[tex]\pi r^2[/tex]

Using the formula

[tex]36\pi=\pi r^2[/tex]

[tex]r^2=36[/tex]

[tex]r=\sqrt{36}=6[/tex] in

Circumference of circle=[tex]2\pi r[/tex]

Using the formula

Circumference of circle=[tex]2\pi (6)=12\pi in[/tex]

Hence, the circumference of circle=[tex]12\pi in[/tex]

=============================================================

Explanation:

We don't have enough information to nail down exact figures, but we can make a range estimate.

The two people (call them A and B) share the profits in the ratio of 4 to 5

In shorthand notation, we can say the ratio is 4:5

This means person A gets 4x dollars while person B gets 5x dollars

The ratio 4x : 5x reduces to 4:5 after dividing both parts by x. The variable x is some positive real number.

The total profit is therefore 4x+5x = 9x dollars

This expression 9x is between 1800 and 3600 dollars, including both endpoints

We then can say...

[tex]1800 \le 9x \le 3600\\\\\frac{1800}{9} \le \frac{9x}{9} \le \frac{3600}{9}\\\\200 \le x \le 400[/tex]

We see that x = 200 is the smallest possible x value. This leads to person A and B receiving 4x = 4*200 = 800 dollars and 5x = 5*200 = 1000 dollars respectively. Note how the ratio 800:1000 reduces to 4:5 after we divide both parts by 200. We can see that 800+1000 = 1800 which is the lowest profit possible.

The inequality above shows that x = 400 is the largest x value possible. If this is the case, then person A receives 4x = 4*400 = 1600 dollars while person B receives 5x = 5*400 = 2000 dollars. The ratio 1600:2000 reduces to 4:5 after we divide both parts by 400. We can see that 1600+2000 = 3600 is the largest profit possible.

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

To summarize:

The actual amount they receive will depend on what the actual profit is. Since we're only given the range of the profit, we can only make an estimated guess of the range for each partner.

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

Side note: For either person, the ratio of the max to min is 2:1. This tells us that the max amount they receive is double compared to the min amount they receive. It's no coincidence that 3600 is double that of 1800.

Probability of yellow disk will be selected is  [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given

n(S) = 25

a. Probability of yellow disk will be selected is O is

n(E) = 25 - 5 = 20

P(E) = [tex]\frac{n(E)}{n(S)}[/tex] =  [tex]\frac{20}{25}[/tex] = [tex]\frac{4}{5}[/tex]

b. It is the probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

Hence, Probability of yellow disk will be selected is  [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.
