The doubling period of a bacteria population is 10 minutes. At time t = 110 minutes, the bacterial population was 800.
goldenfox [79]

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the bacteria population at time t. a represent the initial population at t = 0. Since the doubling period of a bacteria population is 10 minutes, hence:

y=a(2)^\frac{t}{10}

At time t = 110 minutes, the bacterial population was 800. Hence:

800=a(2)^\frac{110}{10} \\\\a = 0.39

At 4 hours (240 minutes):

y=0.39(2)^\frac{240}{10} =6553600

The initial population at time t = 0 was 0.39 while the size of the bacteria population after 4 hours was 6553600

pav-90 [236]

Answer:

Shares of Igor Stravinsky car tires in United state = 8%

Shares of Igor Stravinsky truck tires in United state = 46.15%

Step-by-step explanation:

We have given,

Approximate yearly sales of Igor Stravinsky car tires = 3,760,000

Approximate yearly sales of Igor Stravinsky truck tires = 1,200,000

Also,

Every year about 47,000,000 care tires and 26,000,00 truck tires are sold  in the United States.

Shares of Igor Stravinsky car tires in United state = \frac{3,760,000}{47,000,000} * 100 = 8%

Shares of Igor Stravinsky truck tires in United state = \frac{1,200,000}{26,000,00} * 100 = 46.15%

lapo4ka [179]

Answer:

a. y = x/6 b. 3 heads of lettuce

Step-by-step explanation:

a. Write an algebraic expression Gio could use to determine how much lettuce he needs

Since Gio needs one head of lettuce for every 6 guests who attend, then, the number of lettuce y needed for x guests is one head of lettuce/6 guests × x guests is y = 1/6 × x

= x/6

b. Gio finds out 18 people are coming to the party. Evaluate the expression for 18 guests

Since 18 guest come to the party, x = 6. So, y = x/6

= 18/6

= 3 heads of lettuce.
