<span>The correct answer is: 800
Explanation:
If the threatre holds 1200 people, it means that there are total 1200 seats in the theatre.
2/3 of the total seats are sold; mathematically we can write it as:
(Total-number-of-seats) * (Fraction-of-seats-sold)
1200 * 2/3 = 800
Hence there are 800 tickets are sold.</span>
Answer:
a=c because opposite vertices are always equal to one another
Step-by-step explanation:
Answer:
81
Step-by-step explanation:
(9x - 4)(9x + 4) = ax² - b
81x² - 36x + 36x - 16
= 81x² - 16
=> a = 81
21/22
use y2-y1 / x2-x1
(9-(-12)) / (3-(-19))
21/22
Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
