Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0
Hope this helps :)

After a rain storm, Lily measures the depth of several puddles in her backyard.
How much deeper was the puddle under the swing than the puddle on the sidewalk?
Answer:
3/4 of an inch.
Step-by-step explanation:
The puddle under the swing was 4 inches deeper than the puddle on the sidewalk after the rainstorm.
depth of the puddle under the swing = "x" inches
depth of the puddle on the sidewalk = "y" inches
Difference = Depth of puddle under the swing (x) - Depth of puddle on the sidewalk (y)
For example, if the depth of the puddle under the swing is 8 inches and the depth of the puddle on the sidewalk is 4 inches, the difference would be:
Difference = 8 inches - 4 inches = 4 inches
Therefore, the puddle under the swing is 4 inches deeper than the puddle on the sidewalk.

What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.
Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,
1 km = 1000m
1 m = 1 / 1000 km
1350000 meters = 1350000 / 1000 km
1350000 meters = 1350 km

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!
