Answer:

1 and 1/8 of a batch

Step-by-step explanation:

First you multiply 1/2 by 4 and get for 8 and then you subtract 4/8 - 3/8 and you take the sum of that and add one hole

Answer: 4 x (8 + 5) = (4 x 8) + (4 x 5)

Step-by-step explanation:

multiply the 4 by what is in the ( )

4x8 = 32

4x5= 20

so it equals what is on the other side (in the blanks, you just plug in the 8 and 5)

so it would be

4 x (8 + 5) = (4 x 8) + (4 x 5)

Answer:

Step-by-step explanation:

You have to find two points on the line, that is, two points that satisfy the equation  y=3x+1. But using the equation of the line if you take x=0, you get y=1, so the point (0,1) is on the line. Similarly, you can take x=1 and the equation gives you y=4, so the point (1,4)

belongs to the line. Now you only need to mark these two points on a graph, and draw the line going through them, like so:

graph{3x+1 [-10, 10, -4.44, 5.56]}

Of course, any other pair of points on the line would have been the same, such as (2,7) and (3,10)

When x = -2, y = -1 -3(-2) = -1 +6 = 5.  Therefore, -2, 5 would be a row on your table.

When x = -1, y = -1 -3(-1) = -1 + 3 = 2.  Therefore, -1, 2 would be a row on your table.

Answer:

2310

Step-by-step explanation:

The numbers 2, 3, 5, 7, and 11 are prime.

Therefore, the LCM of those numbers is their product.

LCM = 2 * 3 * 5 * 7 * 11 = 2310

the least common multiple will be 6930.

Answer:

n = 4 - [tex]\frac{5}{19}[/tex]t

Step-by-step explanation:

n determines the amount of water in the bucket, it's basically the total, so that's why it's there. 4 is the number of gallons of water that you started with and 5/19 is the number of gallons that are draining per minute.  t is the amount of time or minutes that have gone by. So, that's why the equation is   n = 4 -[tex]\frac{5}{19}[/tex]t

Answer:

Answer:

Point A and point B have 11 units between

Step-by-step explanation:

If the distance between 0 and 10 is 10 also known as the absolute value, you just add one more unit because it starts at -1

So 10 + 1 = 11 and because we are using 10 is greater than 1 its positive so the answer is 11

Answer:

I can not see the table, so i will answer this in a general way.

Ok, let's see a rough image of what is happening.

First, Joey sends the email to 2 friends.

So first, 2 people have the email

Then each friend sends the email to 3 new people.

So now the number of people that has the email is:

2 + 2*3 = 2 + 6.

Now, the 6 new people that received the email send it to other 3 new people each, so now the number of people that got the email is:

2 + 6 + 6*3

and so on.

We already can see the pattern here, we can write this as:

∑aₙ

Where aₙ = 3*aₙ₋₁

and a₀ = 2.

So with that information, we can find the number of iterations, n, for a given number of people that received the email A.

A = ∑aₙ = (a₀ + a₁ + a₂ + ....) = (2 + 2*3 + 2*3*3 + ...)

Answer: The answer is C

Answer:

B

Step-by-step explanation:

Since the person used >200 kWh that month, you would use the bottom equation: 0.15(x-200)+20.

(BTW, the x>200 or x≤200 means if they used more or less than/equal to 200 hours)

From there, you can plug in the number of hours for x, which is 400. So, 0.15([400]-200)+20

0.15(200)+20

30+20

50

The bill for a person that uses 400 KWh is $50.

Option B is the correct answer.

We have,

The number of kilowatts is more than 200.

So,

From the piecewise function choose the function for x > 200.

i.e

b(x) = 0.15 (x - 200) + 20

This is used to calculate the bill.

Now,

Substitute x = 400 KWh in b(x).

b(x) = 0.15 (x - 200) + 20

Simplify the expression.

= 0.15 (400 - 200) + 20

= 0.15 x 200 + 20

= 30 + 20

Add the values.

= 50

Thus,

The bill for a person that uses 400 KWh is $50.

Answer:

1,000 sq ft

Step-by-step explanation:

Part A:

To find the total area of both rooms (length x width):

(x+4)(2x+6+x-4)

(x+4)(2x+2+x)

2x²+2x+x²+8x+8+4x

= 3x²+14x+8

Part B:

If the length of the game room = 12 ft, we can solve for x:

Game room = (x-4)=12; therefore x=16

Plug 16 in for x in the equation from Part A:

3x²+14x+8 becomes 3(16)²+14(16)+8

= 1,000 sq ft
