The number of hours, t, that bacteria spread 10-fold can be modeled by the equation B(t) = B0(10)4t. There are 50 bacteria present initially and a biologist wishes to find out how many hours will elapse until there are 10,000 bacteria present. What is the exact value for the number of hours elapsed, t, in the equation 10,000 = 50(10)4t?
Answer:
t = (log200)/4 hours
Step-by-step explanation:
10,000 = 50(10)^(4t)
Divide both sides by 50
200 = 10^(4t)
Take the log of both sides
log200 = 4t
Divide both sides by 4
(log200)/4 = t
t = (log200)/4 (exact answer)
t ≈ 0.575257498915995 (numeric approximation)

What is the midpoint of the line with endpoints (3,-2) and (-3,6)
(0, 2)
Step-by-step explanation:
The coordinates of the midpoint of a line segment is given by
[(x2 + x1)/2 , (y2 + y1)/2]
Let P1 = (3, -2) and P2 = (-3, 6)
x-coordinate:
(1/2)(x2 + x1) = (1/2)[(-3) + 3] = 0
y-coordinate:
(1/2)(y2 + y1) = (1/2)[6 + (-2)] = 2
Therefore, the coordinates of the midpoint whose endpoints are (3, -2) and (-3, 6) are
(0, 2)

A normal distribution has a mean of 102 and a standard deviation of 2.9.
What is the z-score of 105?
Enter your answer, rounded to the nearest hundredth, in the box.
Answer:
the z score of 105 is 1.03
Step-by-step explanation:
Given that
the mean is 102
And, the standard deviation is 2.9
We need to find the z score of 105
As we know that
Z score = (Observed value - mean) ÷ standard deviation
= (105 - 102) ÷ 2.9
= 1.03
Hence, the z score of 105 is 1.03
The same would be considered and relevant

You can paint a room in 8 hours. Working together, you and a friend could paint the same room in just 5 hours. How long would it take your friend to paint the room alone.
Answer:
friend alone could do it in 13 hours and 1/3
Step-by-step explanation:
Your rate = room/8
friends rate = room/x
combined rate = room/8 + room/x
= room(x+8)/(8x)
then
5 = room / [room(x+8)/(8x)]
5 = 8x/(x+8)
8x = 5x + 40
3x = 40
x = 40/3 = 13 1/3
friend alone could do it in 13 hours and 1/3
The diameter of a dime is 17.91 millimeters, an the height is 1.35 millimeters. What is the volume of a dime? What is the volume of an oblique cylinder formed by stacking 50 dimes? Round your answers to the nearest hundredth.
Answer:
why does no one ever answer these questionsss?? it's always math to, like I'm just trying to pass my quick check, let alone the class. you know how much easier my life would be it's people just answered the questions. I'm gonna run away, to some Scottish Isle and live a quiet life, in a cozy home with the wind outside ruffling through the grass, and the tired tired sea crashing onto the shoreline. I'll only visit my family and friends once a year, but the rest of the time, I'll be there, in the quiet. eventually a young visitor will stumble through my b & b and he'll end up staying there for weeks, for reasons unknown to me. Then, we'll fall in love, to the quiet sound of the ocean outside. And it'll be just us, it'll be our place, our secret. we won't have to deal with the loud, crazy, hectic world. and it will be perfect. but for now I'm stuck trying to pass this math class.
Answer:
The volume of one dime is 340.11 mm3. The volume of 50 dimes is 17.005.32 mm3.

Here’s how the multiplication works:
Perform the multiplication just as you would for whole numbers.
When you’re done, count the number of digits to the right of the decimal point in each factor and add the results.
Place the decimal point in your answer so that your answer has the same number of digits after the decimal point.

Step-by-step explanation:
So, 14 out of the 25 kids have a dog. If you were to have 125 kids which if 5 times the first 25 kids it would be 14 x 5 which is 70.
tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic equations that tina solved
Answer:
[tex]x^2-\dfrac{9}{2}x-9=0[/tex]
Step-by-step explanation:
The solutions of a quadratic equation are :
x = -3/2 and x = 6
or we can write it as :
[tex]x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0[/tex]
Multiplying both values,
[tex](x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0[/tex]
Hence, the required quadratic equation is [tex]x^2-\dfrac{9}{2}x-9=0[/tex].
Using Cavalieri's Principle, what is the general formula for the volume of a cone?
Answer:
The volume for a cone and pyramid are the same, V = 1/3 Bh where B is the area of the base.
Step-by-step explanation:
So even though the base is a different shape, as long as the areas and heights are the same, they will have the same volume.

c) tan(b)
Write trig. ratios for each.
Answer:
see explanation
Step-by-step explanation:
(1)
(a)
sin(a) = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{15}{17}[/tex]
(b)
cos(a) = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{8}{17}[/tex]
(c)
tan(a) = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{15}{8}[/tex]
----------------------------------------------------
(2)
(a)
sin(b) = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{17}[/tex]
(b)
cos(b) = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{15}{17}[/tex]
(c)
tan(b) = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{8}{15}[/tex]
A sphere shaped orange has a diameter of 7 centimeters. Find the volume of the orange to the nearest tenth.
22cm^3
Step-by-step explanation:
My education system is different so I dont know what nearest tenth would mean in this .
But going mathematically:
Its diameter is 7 centimetres.
So to find its volume we can use the formula pi/d or pi/r^2
Now, 22/7÷7 would be 22cm³.

what is the sum of 5/12 and 4/9
Answer: 31/36
Step-by-step explanation:Add them up..5/12+4/5 you need to convert to a common denominator. Common denominator is 36; 15/36+16/36=31/36
Answer:
[tex]\frac{31}{36}[/tex]
Step-by-step explanation:
To get the sum you have to have the same denominator.
So you have to find out what can 12 and 9 go into without leaving a remainder which is 36.
Then you divide 36 by 12= 3 and 36 by 9= 4
Then you multiply 3 by 5= 15 and 4 by 4= 16
You add then up and you get 31
So 31/36 is the answer.
