A theater has 49 seats in the first row 52 seats in the second row 55 seats in the third row how many seats are in the 16th row
devlian [24]

Answer:

94 seats

Step-by-step explanation:

We solve using Arithmetic sequence formula

an = a + (n + 1)d

Where

a = First term = 49

d = Common difference = 52 - 49 or 55 - 52 = 3

n = 16th row

Hence,

a16 = 49 + (16 - 1)3

a16 = 49 + (15 × 3)

a16 = 49 + 45

a16 = 94

Therefore, the number of seats on the 16th row is 94 seats

How do you write 8 21/40 as a decimal
Anna [14]
<span>to write 8 21/40 as a decimal we need to write the fraction where denominator is a power of 10.
the denominator now is 40, when we multiply 40 by 25, we get 1000.
then the denominator would be a power of 10.
                                                                     
lets multiply the fraction 21/40 by 25 </span>\frac{21*25}{40*25} =  \frac{525}{1000}
<span> 8 21/40 is a mixed fraction made of 8 wholes and a fraction that is now 525/1000.
                                                                   
when dividing by 1000, the decimal point that is after 525 should move 3 decimal places to the left, then the decimal point comes before 525.
then 21/40 is equal to 0.525. since we have 8 wholes;                                                                     8 + 0.525 = 8.525</span>
