Write the equation of a line that is perpendicular to the given line and that passes through the given
point.
y=
-(4,-3)
Answer:
hopes this helps
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.

The area of a circle is 36π in². What is the circumference, in inches? Express your answer in terms of \piπ.
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]

What is the simplified expression of (2x -8) + (3x-2)
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:
[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

Write down an algebraic expression for each of the following statements.
A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
B. The total value of x 20-cent coins and y 5-dollar notes in cents.
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

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.
What is probability?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.

The maximum marks of each subject are 150. A student scores 80% in Maths. In English, he scores 70% of his
score in Maths and in
Hindi, he scores 75% of his score in English. Find his score in each subject.
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
A car drives 160 km in 2 hours.
What is the average speed of the car?
Answer:
The car travelled an average speed of 80 km/h.
Step-by-step explanation:
Distance travelled by the car = 160 km

Average speed = Distance/Time
Average speed = 160/2
Average speed = 80 km/h
The car travelled an average speed of 80 km/h.

Answers:
Person A receives at least 800 dollars, but no more than 1600 dollarsPerson B receives at least 1000 dollars, but no more than 2000 dollars=============================================================
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:
Person A can receive anywhere between 800 dollars and 1600 dollars (inclusive of both endpoints).Person B can receive anywhere between 1000 dollars and 2000 dollars (inclusive of both endpoints).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.
The cost, C. of producing coolers, x, is modeled by the equation C = 0.005x2 - 0.3x + 17. How many coolers are
produced when the cost is $19. Round your answers to the nearest whole number
All work must be clearly shown, step by step, to receive full credit. Separate your work. Each new statement or
equation, must be on a new line.
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
