Last week the number of bacteria in a petri dish was 2.25×102. this week the number of bacteria in the petri dish is 2.75×105. how many times more bacteria are in the petri dish this week? round the decimal to the nearest tenth. there are __ × 10__ times more bacteria in the petri dish this week compared to last week.

(2.75 x 10⁵ ) / (2.25 x 10² )

= (2.75 / 2.25) x 10⁵⁻²

= 1.2 x 10³ times .

(That's 1,200 times as many.)

There are times more bacteria in the petri dish this week compared to last week.

Step-by-step explanation:

Given: Last week the number of bacteria in a petri dish =

This week the number of bacteria in the petri dish =

Now, the number of times more bacteria are in the petri dish this week will be :

Hence, There are times more bacteria in the petri dish this week compared to last week.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
