Answer:

The rule for a reflection over the y -axis is (x,y)→(−x,y).

Step-by-step explanation:

Answer:

a) 235.62 cm³ (nearest hundredth)

b) 2. tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume

Step-by-step explanation:

volume of a cylinder = [tex]2\pi r^2h[/tex]  (where r is the radius and h is the height)

Given:

a) ⇒ volume = [tex]\pi \times 5^2 \times 3=75\pi =235.62[/tex] cm³ (nearest hundredth)

b)  Given:

⇒ volume = [tex]\pi \times 10^2 \times 3=300\pi =942.48[/tex] cm³ (nearest hundredth)

Given:

⇒ volume = [tex]\pi \times 5^2 \times 9=225\pi =706.86[/tex] cm³ (nearest hundredth)

Therefore, 2) tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume

Answer: Only Statement 1 is True.

Step-by-step explanation:

A box is essentially a rectangular prism, which has 8 corners. Tubes, pipes, and cans are cylinders because the corss-section of them are circular and the connection between the bases are parallel.

Answer:

A) 2 : 3

Reason: Since their scale factor is 2 / 3, meaning that the object 2 / 3 of the other same object, so the volume also 2 / 3 of the other object

Division is a mathematical operation that is used to determine the quotient of a set of numbers. The sign used to denote division is ÷.

The first step is to know how many pence makes a pound.

100 pence = 1 pound

The second step is to convert £1 52 p to pence

1 x 100 + 52 = 152p

The third step is to divide, 152 by 2

152/2 = 74p

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

First name the equation

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

+ – +

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Answer:

2000

Step-by-step explanation:

First, we have to find how many votes there were.

Since the losing candidate had 40% of the votes, that means the winning candidate had 60% of the votes.

Let x = amount of votes for losing candidate

x/40 = 900/60

Cross multiply

60x = 36,000

Divide both sides by 60

x = 600

The losing candidate had 600 votes

Add that number to 900 and we find the total amount of votes, which is 1500.

This number is the people who voted.

Now we have to find how many did not vote.

Since 25% of people did not vote, that makes people who did vote 75%

Let y = amount of voters who did not vote

y/25 = 1500/75

75y = 37,500

Divide both sides by 75

75y/75 = 37,500/75

y = 500

This means that 500 voters did not cast a vote.

Add that number to 1500 and we get that the total amount of voters is 2000

Answer:

$3125 dollars

Step-by-step explanation:

Given the following question:

25% of 2500

In order to find the answer, we first will have to use the formula to calculate percentages to find 25% of 2500, then we add that answer onto the initial amount to have our answer.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times 2500}{100} =25\times2500=62500\div100=625[/tex]
[tex]=625[/tex]

Now add:
[tex]2500+625=3125[/tex]
[tex]=3125[/tex]

Which means after a 25% increase the diamond will cost "$3125 dollars."

Hope this helps.

The net income is the difference between the gross income and the total expenses

The net monthly balance is $1975

The monthly income is given as:

Income = $2700

The expenses are given as:

Fixed $625;

Living $1,200 (Annual)

The living expense is given per annual.

So, we start by calculating the monthly living expense

This gives

Living =$1200/12

Living = $100

The net balance is then calculated as:

Net = Income - Living - Fixed

This gives

Net = $2700 - $100 - $625

Net = $1975

Hence, the net income is $1975

Step-by-step explanation:

p=n+ 2/d

Multiply both sides of the equation by d.

pd=dn+2

Swap sides so that all variable terms are on the left hand side.

dn+2=pd

Subtract 2 from both sides.

dn=pd−2

The equation is in standard form.

dn=dp−2

Divide both sides by d.

dn = dp−2/d

Dividing by d undoes the multiplication by d.

n= dp−2/d

Divide pd−2 by d.

n=(p−2)/d

Step-by-step explanation:

We can find the slope by using two points on the line itself.

Lets use the points (0, -3) and (6, 0)

The slope's equation is [tex]\frac{y2 - y1}{x2-x1}[/tex]

Thus we get [tex]\frac{0 - - 3}{6-0} = \frac{1}{2}[/tex]

So the slope is 1/2

Hope that helps!

Answer:

slope = 1/2

Step-by-step explanation:

Use the formula:
[tex]\frac{dy}{dx}[/tex] OR  change in y/change in x

If we take an x value of -6 and y value of -3 we get 1/2 as the answer.
