Answer:
4. The relationship is proportional because, for every 12 students, there is one chaperone and when you multiply 12 by the number of chaperones you get the same numbers that the table shows.
1. the relationship is proportional.
45/1= 45
45/2 = 90
45/3 = 135
45/3 = 180
2. the constant of 2 is 10. the constant of 3 is 2.
the relationship between x and y is that x divided by y equals the constant.
4. x divided by y equals the constant, or
x÷y=c(constant)
hope that helps and sorry for taking so long
Answer: the length is 15 m and the width is 5 m
Step-by-step explanation:
Let L represent the original length of the rectangle.
Let W represent the original width of the rectangle.
The length of a rectangle is three times it's width. This means that
L = 3W
If the width is diminished by 1 m and length is increased by 3 m, the area of the rectangle that is formed is 72 m². This means that
(L + 3)(W - 1) = 72
LW - L + 3W - 3 - 72 = 72 + 3
LW - L + 3W = 75 - - - - -- - - - - - 1
Substituting L = 3W into equation 1, it becomes
3W × W - 3W + 3W = 75
3W² = 75
W² = 75/3 = 25
W = √25 = ±5
The width cannot be negative. Therefore, the width is 5 m
L = 3W = 3 × 5 = 15 m
Answer:
Yes, you are correct
Step-by-step explanation:
You can use a factor tree to find the factorization of a number is to divide out prime numbers only. For example: Number 24
24
12 2
6 2
3 2
2 is a primer number, so thats why im dividing it by that number
The sticker price of the car can be calculated by deducting from the msrp (manufacturer's suggested retail price) the sport package price, stereo package price and the destination charge.
sticker price of the car = ($19,150) - ($2500 + $600 + $600)
sticker price of the car = $15,450
<em>Hence, the sticker price of the car is $15,450. </em>
