A new shopping mall is gaining in popularity every day since it open the number of shoppers is 20% more than the numbers of shop
erastovalidia [21]

Answer: the number of shoppers on the first day is 125

Step-by-step explanation:

The number of shoppers is 20% more than the numbers of shoppers the day before. It means that the number of shoppers is increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = (ar^n - 1)/(r - 1)

Where

n represents the number of term in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

r = 1 + 20/100 = 1.2

n = 4(first 4 days)

S4 = 671

Therefore, the expression for the first 4 days is

671 = (a × 1.2^(4) - 1)/1.2 - 1

671 = (a × 1.2^(4) - 1)/0.2

671 = 1.0736a/0.2

671 = 5.368a

a = 671/5.368

a = 125

A restaurant wishes to have at least one server for every 12 tables. Each of the tables in the restaurant seats four guests. If
Fiesta28 [93]
X = number of servers
y = number of guests

\text {number of guest per table = } 4<span>

</span>\text {number of tables = } \dfrac{y}{4}
<span>
</span>\text {number of servers needed = } \dfrac{y}{4} \div 12<span>

</span>\text {number of servers needed = } \dfrac{y}{4} \times  \dfrac{1}{12}

\text {number of servers needed = } \dfrac{y}{48}

There must be at least 1 server for every 12 tables:
x \geq \dfrac{y}{48}

What is the measure of ∠4? Enter your answer in the box.
charle [14.2K]

Step-by-step explanation:

\angle 4, \:60\degree \:\&\:61\degree are straight line angles.

\therefore \angle \: 4 + 60 \degree + 60 \degree = 180\degree \\  \\  \therefore \:  \angle \: 4 = 180\degree - 121\degree \\  \\ \huge \red {\boxed {\therefore \:  \angle \: 4 = 59\degree}}
