Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.

Which of the following equations is equivalent to 3 • 12 = 36?
36 + 3 = 12
36 ÷ 3 = 12
36 • 3 = 12
36 – 3 = 12
Answer:
B
Step-by-step explanation:
36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.
36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
One page of a petition can hold p signatures. You were able to get 4p+5 people to sign the petition. Your friend was able to get 2p−3 people to sign the petition. Write an expression in simplest form that represents the number of people that you and your friend got to sign the petition.
Answer:
6p - 2
Step-by-step explanation:
The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.
4p + 5 + 2p - 3
4p + 2p + 5 - 3
6p - 2
Therefore, the total and simplified expression for the total number of signatures would be 6p - 2
A company rents out 14 food booths and 26 game booths at the county fair. The fee for a food booth is $175 plus $8 per day. The fee for a game booth is $65 plus $7 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
The expression is ________
Answer:
$4140 + $294d
Step-by-step explanation:
Hello,
Let's write down what we know first,
d days
14 food baths -- $175 and $8 per day
26 game booths -- $65 and $7 per day
What we want to find the amount of money paid for both food baths and game booths so after finding them individually, we need to add them up.
We already know the company rents out 14 fb and 26 gb and we know that each fb is 175 dollars and each gb is 65 dollars, so we should find out the cost of buying them. We can also write out the total cost of
14 * $175 = $2450
26 * $65 = $1690
Now lets find the per day cost,
14 * $8 * d = $112d
26 * $7 * d = $182d
With both equations added together we get,
$2450 + $112d
$1690 + $182d
Add those together and we get:
$4140 + $294d
Add the following complex numbers: (2 + 3i) + (3 - 2i)
Answer:
5 + i
Step-by-step explanation:
Combine real part ans combine imaginary parts
2 + 3i + 3 - 2i = 2 + 3 + 3i - 2i
= 5 + i
Answer:
5 and 1i
Step-by-step explanation:
So you’re adding the following complex numbers: (2 + 3i) + (3 - 2i)
normally if you see a (-) in front of a number, that means it’s negative so we’re gonna think about this as -2i and positive 3.
so you’re gonna want to take the 2 regular while numbers (without the variable) and then add those together. they’re like numbers so neither of them have a variable, which means they can easily be added, but you can’t add a number like 7 to a number like 9h because there’s a variable.
Now that you’ve added the 2 and 3, you get 5 right? so now you’re gonna take the 3i and -2i, and add those together. since the number 3i is bigger than -2i, the ending number after you add those is gonna be positive, and it’s gonna be 1i.
now i’m not sure if you’re supposed to make an equation out of this but you’re answer will be 5 and 1i or 5 + 1i
also if you don’t want to put 1i, 1i is the same as just “i”. so you can put 5 + i :)

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, tt, and the number of chairs sold, cc, that would satisfy the constraint.
Answer: 150c + 400t ≥ 4900
Step-by-step explanation:
Let the number of chairs sold = c
Let the number of tables sold = t
Price for each chair = $150
Price for each table = $400
The inequality that could represent the number of tables and chairs sold will be:
(150 × c) + (400 × t) ≥ 4900
150c + 400t ≥ 4900

Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio? Does this represent an exponential function?
Answer:
The function have a constant ratio
No, it does not represent an exponential function.
Step-by-step explanation:
As given,
Ines has saved $5. She doubles the amount she saves each week.
⇒ In first week she saved = $5
In second week she saved = 2×$5 = $10
In third week she saved = 2×$10 = 20
In fourth week she saved = 2×$20 = 40
and so on..
∴ we get the series
5, 10, 20, 40 ,.......
If the series is given as a, b, c, d, ..... , then
The common difference is defined as d = b-a = c-b
The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]
Here, in the given question
The series is - 5, 10, 20, 40
This has no common difference , d = 10 - 5 (= 5 )≠ 20 - 10 (= 10)
As 5 ≠ 10
So the function does not define common difference .
Now,
This has common ratio , r = [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]
As 2 = 2
So, the function represent common ratio
Now,
The function does not represent an exponential function because it is increased by common ratio.
