Answer:
x/3=y/2
Step-by-step explanation:
Multiply both sides of the equation by the Common Denominator 6
2x + 6 = 3y + 6
2x = 3 y
x/3 = y/2
Which is a zero of the function f(x) = 2x – 6?
2
-3
-6
3
Answer and explanation:
The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.

State whether 2.5 + π is rational or irrational. Explain.
Answer: 2.5 + π is an irrational number.
Step-by-step explanation:
Irrational numbers are numbers that can not be written as the quotient of two integer numbers, and they have an infinite number of digits after the decimal point (such that there is not periodicity in these digits).
So suppose that we have an irrational number and we add 1, then the infinite digits after the decimal point will still be there, so the sum will be also an irrational number.
The same can be seen for the sum between an irrational number and a rational number, where the infinite number of decimals after the decimal point will still be there (because the rational numbers have a finite or infinite but periodical decimals after the decimal point), so the sum between an irrational number and a rational number is always irrational.
In this case, we have the addition:
2.5 + π
Which is the sum of a rational number and an irrational number, so we can conclude that this is an irrational number.
Which equation represents a line passing through the point (8, 9) with a slope of 3?
The equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.
What is the equation of a line passing through two given points in 2-dimensional plane?Suppose the given points are [tex](x_1, y_1) and (x_2, y_2),[/tex]
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
We have been given a line passing through the point (8, 9) with a slope of 3.
then the equation of the straight line joining both two points is given by
[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]
Its slope would be:
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
m = 3
Therefore, the equation of the straight line
[tex](y - 9) = 3 (x -8)\\\\y - 9 = 3x - 24\\\\y = 3x -15[/tex]
Hence, the equation of a line passing through the point (8, 9) with a slope of 3 is y = 3x - 15.

In one company, 20% of the workers in the technical department applied for vacation at the same time. If 12 workers applied for vacation, how many tech workers are there, altogether?
Answer:
There are 60 tech workers altogether
Step-by-step explanation:
Let X be the total number of tech workers in the company
Out of X tech employees, 20 % applied for leaves
In totality, 12 tech employees are on leave
Thus,
[tex]\frac{20}{100} * X = 12[/tex]
On solving the above mathematical equation, we get -
[tex]X = \frac{12*100}{20} \\X = 60[/tex]
Hence, there are 60 tech workers altogether
Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.4.
Independently, she then decides whether or not to buy a CD, with a probability of 0.3 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)

find the domain and range of f(x)= -2x²+3
Answer is in pictures and work as well
Answer:
you need to know what domain and range mean... so remember domain is the input.... range is the output.. :)
Step-by-step explanation:
the input .. "x" in this case.. can be any number .. so the domain is all real numbers.
the output.. or range.. is limited.. b/c the square on the 'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative. : | hmmmm so when is that squred term the smallest it can be? hmmm when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...
the range is from -∞ to 3

Find the smallest number such that the remainder is 3 when it is divided by 16,20 or 24.
(step required,thank you)
Answer: 123
Step-by-step explanation:
Foe us to solve this, we have to find the lowest common multiple of 16, 20 and 24 first and then add 3 to the LCM. This goes thus:
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160
Multiples of 20 = 20, 40, 60, 80, 10, 120, 140, 160
Multiples of 24 = 24, 48, 72, 96, 120
Therefore, the Lowe's common multiple is 120.
We then add the remainder of 3 and this will give:
= 120 + 3
= 123

Marley walked around 2 rectangular parks. One measures 54 feet by 38 feet and the other measures 32 feet by 22 feet. How far did she walk?
Answer:
Step-by-step explanation:
Perimeter of Park 1 = 2*(54+38)
= 2 * 92
=184 feet
Perimeter of park 2 = 2*(32+ 22)
= 2 * 54
= 108 feet
Total distance = Perimeter of park 1 + perimeter of park 2
= 184 + 108
= 292

Answer:
774.25
Step-by-step explanation:
8.75 becomes .0875 because it is 8.75%/100%
711.95 x .0875 = 62.295625
add the cost (711.95) and the tax (62.295625)
711.95 + 62.295625 = 774.245625
rounded = 774.25

Answer:
128 banana's... I would work it all out for u but the teacher just came in my room and had a go
Answer: 128
Step-by-step explanation:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
20% = 20/100 = 20 ÷ 100 = 0.2.
100% = 100/100 = 100 ÷ 100 = 1.

Complete the statements about the cone.
The height is units.
The radius is units.
The volume is Tot cubic units.
10
6
Answer:
The answers are:
The height is 6
The radius is 8
The volume is 128 π cubic units.
Step-by-step explanation:
The height is shown in the picture. So the first answer is 6.
To find the radius, you use the equation. [tex]\sqrt{slant height^{2}- height^{2} }[/tex] = radius
The slant height 10, and the height is 6. So you plug those into the equation and solve.
[tex]\sqrt{10^{2}-6^{2} }[/tex] =
[tex]\sqrt{100-36}[/tex] =
[tex]\sqrt{64}[/tex] = 8
So the radius is 8.
Now we use the equation [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex] = volume.
[tex]\pi[/tex][tex]8^{2}[/tex] [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex]64 [tex]\frac{6}{3}[/tex] =
[tex]\pi[/tex] 64(2) = 128 [tex]\pi[/tex] cubic units
I hoped this helped you. I would love brainiest.
The statements about the cone is that,
The height is 6 units, the radius is 8 units and the volume is 128π cubic units.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given a cone.
We have to find the complete the statements related to the cone.
From the figure,
height of the cone = 6 units
Using the Pythagoras theorem,
Radius of the cone = √(10² - 6²) = 8 units
Volume of the cone = 1/3 π r² h
= 1/3 π × 8² × 6
= 128π cubic units
Hence the height, radius and volume of the cone are 6 units, 8 units and 128π cubic units respectively.
