Simon makes a model of a boat, using a scale of 1 : 30
If the model has a height of 40 cm, find the height of the real boat.
Give your answer in metres.
Answer: 12 metres
Step-by-step explanation:
The scale factor used for the model is 1 : 30.
This means that for any 1cm on the model, the real boat would be 30 cm.
If the height is 40 cm on the model, the real boat will be 30 times that:
= 40 * 30
= 1,200 cm
A metre is equivalent to 100cm.
1,200 cm would therefore be:
= 1,200/100
= 12 metres
$35 bill before tax
tax:5.8%
Tip:21%
Answer:
If tip goes only on amount but not on tax: $44.38
If tip goes on total including tax: $44.81
Step-by-step explanation:
If the tip is applied to the price before tax, then we need to add 5.8% and 21% of $35 to $35.
tax + tip = 5.8% + 21% = 26.8%
100% + 26.8% = 126.8% = 1.268
1.268 * $35 = $44.38
If the tip is applied to the price plus tax, then we calculate the amount including tax first, then we add the 21% tip based on that price.
Bill before tax: $35
Add 5.8% tax: 1.058 * $35 = $37.03
Add tip to the amount including tax: 1.21 * $37.03 = $44.81

how do I simply 4/6
Answer:
Your Answer Is 2/3
Step-by-step explanation:
First you have to find what number are both divisible by, in this case 2.
Next you divide: 4÷2=2 and 6÷2=3
Since 4 was your numerator you put 2 on the top and Since 6 was the denominator you put 3 on the bottom.
Cinemark is having a summer special.If you get a membership one-time cost is $12.50 plus $2.00 per movie that you watch.Write a linear equation that will show the cost of membership and each movie seen
Answer:
Y=12.50x+2.00
Step-by-step explanation:
The linear equation that will show the cost of membership and each movie seen will be C = 2n + 12.5.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Cinemark is having a summer special. If you get a membership one-time cost is $12.50 plus $2.00 per movie that you watch.
The slope of the line is $2.00 and the y-intercept of the line is $12.50.
Let C be the total cost and n be the number of movies. Then the linear equation will be
C = 2n + 12.5

Answer: The amount of hotdogs you would need to sell in order to reach $300= 80
Step-by-step explanation:
Find how much money is spent per hotdog:140÷70=2
$140= Amount made by selling 70 Hotdogs
70=Amount of Hotdogs sold already
Dividing 140 by 70 will get you the cost of 1 hotdog. This is due to division being the act of separating something into parts. There are 70 parts (or hotdogs) in this equation so therefore by separating the amount of money made by those selling those parts, the amount per hotdog would be found.
2. Find the amount of hotdogs it would take to earn a total of $300:
300-140= 160 160÷2= 80
The question asks for a total of $300 to be earnt by selling hotdogs. $140 has already been earnt, therefore a portion of the total amount has been made. By subtracting the amount already made by the total amount of money that is wanted to be earnt, the amount of money needed to reach the $300 is found. The $160 is then divided by the amount of money spent per hotdog ($2). The answer (80) is the amount of hotdogs required to be sold to reach the goal of $300.

Plsssss helpppppppppp meeeeeeeeee
Answer:
x = 14, y = 37
Step-by-step explanation:
The angle vertical to (9x + 12 )° and 3x are same- side interior angles and are supplementary, sum to 180°, then
9x + 12 + 3x = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14, so
3x = 3 × 14 = 42
3x and 4y - 10 are adjacent angles and supplementary, then
3x + 4y - 10 = 180
42 + 4y - 10 = 180
4y + 32 = 180 ( subtract 32 from both sides )
4y = 148 ( divide both sides by 4 )
y = 37

A quadrilateral has three angles that measure 88°, 82°, and 55°. Find the unknown angle measure.
Answer: 135° is the unknown angle measure.
Step-by-step explanation: We know a quadrilateral has 4 angles and measure a total of 360°.
To find the unknown angle simply add all the 3 angles and then subtract them from 360°.
Follow the steps:
88° + 82° + 55° = 225°. (Added the 3 angles)
360° - 225° = 135°. (Subtract the sum of the 3 angles from 360 degrees)

Last question on homework I’m having trouble with ^_^
Answer:
25 + h
f^2
Step-by-step explanation:
It says the sum of 25 and h which is 25 + h.
Now, it basically says "25 + h" is divided by f cubed. Cubed means to the power of 2 (the exponent), so f cubed would be f^2 (f to the power of 2).
25 + h is divided by f^2
25 + h
f^2
(the reason I put "^2" is because I don't know how to put exponents on here, sorry)

2/5 of the 45 oranges fell out of the tree. how many oranges fell out of the tree?
Answer:
18 oranges
Step-by-step explanation:
To find this, we have to calculate 2/5 * 45, which is equal to 45 * 2 and then divided by 5 (Or you could cross cancel). 45 * 2 is equal to 90 and 90/5 is equal to 18. That means that 18 oranges fell out of the tree.
