Answer:
x = 34.5
Step-by-step explanation:
x - 15.4 = 19.1
Add 15.4 to both sides.
x - 15.4 + 15.4 = 19.1 + 15.4
x = 34.5
Answer:
Hourly growth rate is 4.24%
Step-by-step explanation:
The formula or exponential growth is given by:
![y = a*(1+r)^n](https://tex.z-dn.net/?f=y%20%3D%20a%2A%281%2Br%29%5En)
Where
y is the instantaneous value of growing culture
a is the initial value of growing culture
r is the 'hourly' growth rate
n is the number of hours passed
As per given values:
y = 1997; a = 1800; n = 2.5
![1997 = 1800*(1+r)^{2.5}](https://tex.z-dn.net/?f=1997%20%3D%201800%2A%281%2Br%29%5E%7B2.5%7D)
![1.10944=(1+r)^{2.5}](https://tex.z-dn.net/?f=1.10944%3D%281%2Br%29%5E%7B2.5%7D)
![1+r = 1.0424](https://tex.z-dn.net/?f=1%2Br%20%3D%201.0424)
Hence, growth rate is:
r = 0.0424 = 4.24%
Answer:
x= -1/8
Step-by-step explanation:
8x(6)+12−4=2
Step 1: Simplify both sides of the equation.
8x(6)+12−4=2
Simplify: (Show steps)
48x+8=2
Step 2: Subtract 8 from both sides.
48x+8−8=2−8
48x=−6
Step 3: Divide both sides by 48.
48x
48
=
−6
48
x=
−1
8
Answer:
x= -1/8
Answer:
Ratio of online sales to shop sales = 3 : 1
Step-by-step explanation:
Total necklace sold in a month = 240
Necklace sold via shop's website = 180
the rest were sold in a high street shop.
Necklace sold via high street shop = Total necklace sold in a month - Necklace sold via shop's website
= 240 - 180
= 60
Necklace sold via high street shop = 60
Ratio of online sales to shop sales
Necklace sold via shop's website : Necklace sold via high street shop = 180 : 60
= 180 / 60
= 3 / 1
= 3 : 1
Ratio of online sales to shop sales = 3 : 1
