The bar graph shows the number of customers at a nail salon each day for one week. What percent of the customers came on Friday

mixer [17]

Answer:

Friday = 11.43%
Saturday = 17.14%
Friday & Saturday = 28.57%

Step-by-step explanation:

Total number of customers

⇒ 15 + 5 + 10 + 14 + 8 + 12 + 6 = 70

Percentage of customers who came on Friday

$\begin{aligned}\implies \sf Percentage & = \sf \dfrac{Friday\:customers}{Total\:number\:of\:customers} \times 100\\\\& = \sf \dfrac{8}{70} \times 100\\\\& = \sf 11.43\%\:\:(nearest\:hundredth)\end{aligned}$

Percentage of customers who came on Saturday

$\begin{aligned}\implies \sf Percentage & = \sf \dfrac{Saturday\:customers}{Total\:number\:of\:customers} \times 100\\\\& = \sf \dfrac{12}{70} \times 100\\\\& = \sf 17.14\%\:\:(nearest\:hundredth)\end{aligned}$

Percentage of customers who came on Friday and Saturday

$\begin{aligned}\implies \sf Percentage & = \sf \dfrac{Fri\:and\:Sat\:customers}{Total\:number\:of\:customers} \times 100\\\\& = \sf \dfrac{8+12}{70} \times 100\\\\& = \sf 28.57\%\:\:(nearest\:hundredth)\end{aligned}$

What is the answer to (3x) to the 5th power

viva [34]

Answer:

Step-by-step explanation:

Given that

(3x) is raised to power 5

(3x)^5

Then,

Using indices

(AB)ⁿ = Aⁿ•Bⁿ

Then,

(3x)^5= 3^5•x^5

Then, 3^5 means=3×3×3×3×3=243

So,

(3x)^5= 243x^5
