Answer:
31.5 litres
Step-by-step explanation:
If Mel uses all 30 litres of yellow paint, then:
5 / 2 = 30 / x
5x = 60
x = 12
Mel would need 12 litres of blue paint, but she only has 9 litres. So the amount of yellow paint she needs is:
5 / 2 = x / 9
2x = 45
x = 22.5
Mel will use 22.5 litres of yellow paint with 9 litres of blue paint to make a total of 31.5 litres of green paint.
Answer:
41%
Step-by-step explanation:
Given the cash price is $500, the hire purchase price is calculated by summing the installment and down-payment:

#Percentage increase in price is the difference between the hire purchase price and list price as a percentage of the list price:

Hence, the % increase in price is 41%
A^2 + b^2 = c^2....a and b are ur legs and c is ur hypotenuse
18^2 + 80^2 = c^2
324 + 6400 = c^2
6724 = c^2
sq rt 6724 = c
82 = c.....so the hypotenuse is 82 cm
The cost of the apples is a function of their weight option (A) is correct because the independent variable (x) is the weight of the apples.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
- A. The cost of the apples is a function of their weight.
- B. The weight of the apples is a function of the number of apples.
- C. The cost of the apples is a function of the type of apples.
- D. The weight of the apples is a function of their cost.
From the graph:
The y-axis is representing the cost(c) of the apples in dollars and
The x-axis is representing the weight(w) of the apples in pounds.
c = f(w)
The independent variable (w) is the weight of the apples
The dependent variable (c) is the cost of the apples
Thus, the cost of the apples is a function of their weight option (A) is correct because the independent variable (w) is the weight of the apples.

Answer: 6 times
Step-by-step explanation:
Let the Length of the rectangle be L and the Width be W
Also , let us pick the Length as the longest side , then from the statement
L = 2W
The perimeter of a rectangle is given as :
P = 2 ( L + W )
substitute L = 2W into the formula , we have
P = 2 ( 2W + W )
P = 2 (3W)
P = 6W
Therefore the Perimeter is 6 times as long as the Width
