A boa constrictor is 18 inches long at birth and grows 8 inches per year. Write an equation that represents the length Y (in feet) of a boa constrictor that is X years old.

This is writing equations in slope intercept form and I tried y=8x+18 but it didn't work.

Answers

Final answer:

The length Y (in feet) of a boa constrictor that is X years old is given by the equation Y = 0.6667X + 1.5. This equation takes into account the initial length of 1.5 feet at birth and an annual growth of 0.6667 feet.

Explanation:

To write an equation representing the length Y (in feet) of a boa constrictor that is X years old, we need to start with its initial length at birth and account for its growth over the years. The boa constrictor is 18 inches long at birth and grows 8 inches per year. However, we want Y to be in feet, so we must convert these measurements from inches to feet (since 1 foot = 12 inches).

To convert the initial length from inches to feet, we divide 18 inches by 12, which gives us 1.5 feet. The annual growth should also be converted from inches to feet by dividing 8 inches by 12, resulting in approximately 0.6667 feet.

So, using slope-intercept form (Y = mx + b), our equation is:

Y = 0.6667X + 1.5

This equation states that the boa constrictor starts with a length of 1.5 feet at birth (Y-intercept) and grows about 0.6667 feet for every year that passes (the slope).

Josie has 250 cubic centimeters of candle wax. She wants to make a hexagonal prism candle with a base area of 21 square centimeters and a height of 8 centimeters. She also wants to make a triangular prism candle with a height of 14 centimeters. Can the base area of the triangular prism candle be 7 square centimeters?

Answers

Let's compute the volume of the hexagonal prism candle. That volume is

Volume = (area of base)*(height)
Volume = 21*8
Volume = 168

The volume of the hexagonal prism candle is 168 cubic cm

So we have 250-168 = 82 cubic centimeters of wax leftover. 

Let V = 82 be the volume of the triangular prism. We're given the height to be 14 so h = 14

Use V = 82 and h = 14 to find the area of the base (A)

V = A*h
82 = A*14
82/14 = A*14/14
A = 5.857 ... this is approximate

The base area is about 5.857 square cm which is less than 7 square cm. So it's impossible for the base area to be 7 square cm. The area of the base must be 5.857 (approx) or smaller if we want the height to be 14 cm. 

The answer to the question in the problem is simply "no" with the reasoning explained above. 

Rhonda bought her son an inflatable pool for the summer. It took her 20 mins to fill the pool to a depth of 6 in. What is the unit rate per minute(in per minute)

What is the unit rate per inch(mins per in)

Answers

Per means one. So this asks for in one minute, and in one inch.
20 minutes = 6 inches.
So dividing by 20 gets you one minute.
1 minute = 6/20 inches
1 minute = 3/10 inches

20 minutes = 6 inches.
So dividing by 6 gets you one inch.
20/6 minutes = 1 inch
10/3 minutes = 1 inch

Convert 7.7km into miles if 1.6 km = 1 mile

Answers

This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers

If you can buy 1⁄3 of a pound of turkey for 4 dollars, how much can you purchase for 10 dollars? Write your answer as a fraction of a pound.

Answers

The answer is 5/6 of a pound.

Answer:

[tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1 such as 3 meter per second or 4 miles per hour.

As per the statement:

If you can buy 1⁄3 of a pound of turkey for 4 dollars

by definition of unit rate we have;

[tex]\text{Unit rate per dollars} = \frac{\frac{1}{3} }{4} = \frac{1}{12}[/tex] pound of turkey.

We have to find how much can you purchase for 10 dollars.

[tex]\text{Weight of turkey for 10 dollars} = \text{Unit rate per dollars} \times 10[/tex]

⇒[tex]\text{Weight of turkey for 10 dollars}=\frac{1}{12} \times 10 = \frac{5}{6}[/tex] pound

Therefore, [tex]\frac{5}{6}[/tex] pound of turkey you purchase for 10 dollars

Answers

C is your answer because 78+3 is 81 12x7 is 84 so you will have 3 seats left
First, you need to do 78+3 to get 81.

That is how many people are there.

Now you have to divide 81 by 12.

You will get 6.75

This means that your answer will be C because there needs to be 7 rows, and 3 chairs will be left over!

Antoine and 3 friends divide some pennies evenly among themselves. Each friend separates his pennies into 3 equal stacks with 5 pennies in each stack. write a multiplication sentence that shows

Answers

Answer:

4 × ( 3 × 5 ) = 60

Step-by-step explanation:


Answer:

4 × (3 × 5) = 60

Step-by-step explanation:

Total number of persons including Antony = 4

Number of stacks separated by each friend = 3

Number of pennies in each stack = 5

Number of pennies in all 3 stacks of one friend = 3 × 5

Number of pennies in all 3 stacks of 4 persons = 4 × (3 × 5) = 60

Hence, the multiplication sentence is 4 × (3 × 5) = 60.
