A rectangular auditorium seats 1344 people. The number of seats in each rows exceeds the number of rows by 20. Find the number o

Tasya [4]

Let the number of rows be x

rows = x
seats in each row = x + 20

total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28

Therefore,
x = 28
x + 20 = 48

Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)

Ans:There are 48 seats per row

Maria bought g gallons of gasoline for $3.95 per gallon and c cans of oil for $4.45 per can. a. What expression can be used to

Furkat [3]

Answer:

a.) Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.) Total amount spent by Maria = $ 74.02

Step-by-step explanation:

As given,

Cost of gasoline = $ 3.95 gallon

Cost of oil per can = $ 4.45

Also given,

Maria bought g gallons of gasoline and c cans of oil

⇒ Total cost of g gallons of gasoline = g×3.95 = $3.95g

Total cost of c cans of oil = c×4.45 = $4.45c

Now,

a.)

Total amount spent on gasoline and oil = $ ( 3.95g + 4.45c )

b.)

As given ,

Maria buy gasoline , g = 8.6 gallons

Maria buy cans of oil , c = 6

So,

Total amount spent = $ 3.95(8.6) + 4.45(9)

= $ 33.97 + 40.05 = $ 74.02

⇒Total amount spent by Maria = $ 74.02

Which of the following is a root of the polynomial shown below f(x)=x^3+2x^2-x-2

Aleks [24]

F(x) = x^3 + 2x^2 - x - 2
f(x) = x^2(x + 2) - (x + 2) 
f(x) = (x^2 - 1)(x + 2) 
f(x) = (x + 1)(x - 1)(x + 2) 
Roots: -1, 1, -2

The growth of a sample of bacteria can be modeled by the function bt=1001.06t where b is the number of bacteria and t is time in

alukav5142 [94]

Given:

The growth of a sample of bacteria can be modeled by the function

$b(t)=1001.06t$

where, b is the number of bacteria and t is time in hours.

To find:

The number of total bacteria after 3 hours.

Solution:

We have,

$b(t)=1001.06t$

where, b is the number of bacteria and t is time in hours.

Substituting t=3, we get the number of total bacteria after 3 hours.

$b(3)=1001.06(3)$

$b(3)=3003.18$

Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.

$b(3)\approx 3003$

Therefore, the number of total bacteria after 3 hours is about 3003.
