Step-by-step explanation:
Answer:
16
Step-by-step explanation:
The existence of the constant rate of change is given the ratio of y to x is the same. Then:
![k_{1} = \frac{80}{5}](https://tex.z-dn.net/?f=k_%7B1%7D%20%3D%20%5Cfrac%7B80%7D%7B5%7D)
![k_{1} = 16](https://tex.z-dn.net/?f=k_%7B1%7D%20%3D%2016)
![k_{2} = \frac{64}{4}](https://tex.z-dn.net/?f=k_%7B2%7D%20%3D%20%5Cfrac%7B64%7D%7B4%7D)
![k_{2} = 16](https://tex.z-dn.net/?f=k_%7B2%7D%20%3D%2016)
![k_{3} = \frac{96}{6}](https://tex.z-dn.net/?f=k_%7B3%7D%20%3D%20%5Cfrac%7B96%7D%7B6%7D)
![k_{3} = 16](https://tex.z-dn.net/?f=k_%7B3%7D%20%3D%2016)
In consequence, the constant rate of change is 16.
Hello! So Brittany plans to sell car magnets that she purchased at $7.50 and mark them up by 30%. To find the new price, we can multiply 7.50 * 1.30. When multiplied, it gives us 9.75. Brittany is planning to charge $9.75 for the car magnets.
Answer:
Length of spaceship in movie = 528
Step-by-step explanation:
Given that:
Drawing ratio of spaceship = 1 : 24
It means that 1 inch on drawing equals 24 inches in movie
Drawing of spaceship = 22 inches
Length of spaceship in movie = x
As the relationship is proportional,
1 : 24 :: 22 : x
Product of mean = Product of extreme
24*22 = x
x = 528
Hence,
Length of spaceship in movie = 528
<h2>
Answer:The number of milk chocolates are 18 and the number of dark chocolates are 24.</h2>
Step-by-step explanation:
Let the number of milk chocolates be
.
Let the number of dark chocolates be
.
Given that the box contains the milk and dark chocolates in the ratio
.
So,
...(i)
Given that the total number of chocolates are
.
So,
. ...(ii)
Using (i) and (ii),
![m+\frac{4}{3}m=42](https://tex.z-dn.net/?f=m%2B%5Cfrac%7B4%7D%7B3%7Dm%3D42)
![\frac{7}{3}m=42](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7Dm%3D42)
![m=18](https://tex.z-dn.net/?f=m%3D18)
![d=\frac{4}{3}m=\frac{4}{3}\times 18=24](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B4%7D%7B3%7Dm%3D%5Cfrac%7B4%7D%7B3%7D%5Ctimes%2018%3D24)
So,the number of milk chocolates are
and the number of dark chocolates are
.
