From the given equation, [tex]4^{t}[/tex] represent the number of bacteria increases by a factor of 4 each day.

An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

A microbiologist during a study on a culture of 250 bacteria noticed that he can model the number of bacteria after t number of days by the equation

[tex]B = 250 \times[/tex] [tex]4^{t}[/tex]

t stands for training days(Add one to the power of 4 every day)

Every day is four time more than the day before.

So, the number of bacteria increases by a factor of 4 each day.

So, this answer is Option C.

Answer 813.8

Step-by-step explanation:

Well 813.8 is the answer. Why? Lets talk it out if there are 75 submissions and it says Paul will accept 2/5 of the submissions so we have to do is 75- 2/5 will be 74.6 and multiply by 13 because 13 pages is in a article so we got 969.8 and then minus 156 because it asking us how many "more" pages they need so 813.8 is the answer if you subtract 969.8 and 156.

Answer:

1,099 cubic inch or 18.01 liter

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Radius (r) = 5 inches

Height (h) = 14 inches

So, Volume of can = π[tex]r^{2}[/tex]h

By putting the value in the formula, we get

= π [tex]5^{2}[/tex] × 14

= π 25 × 14

= 350π

= 350 × 3.14

= 1,099 cubic inch

As 1 liter = 61.02 cubic inch

So, 1,099 ÷ 61.02 = 18.01 liter

Answer:

49.6% of container A is still full

Step-by-step explanation:

volume of a cylinder : pi×r²×h

Va = pi × 12² × 15 = pi×144×15 = 6785.84013... ft³

Vb = pi × 8² × 17 = pi×64×17 = 3418.05281... ft³

how much of A is still filled, when B has been completely filled ?

Va left = Va - Vb = 3367.78732... ft³

100% of Va = 6785.84013... ft³

1% of Va = 67.8584013... ft³

so, how often does 1% of Va fit into the remaining filing volume of A (Va left) ?

3367.78732... / 67.8584013... = 49.6(2962963...)%

Answer:

Step-by-step explanation:

When we divide congruent sides of similar solids or plane figures we get the linear scale factor.

The square of the linear scale factor gives the area scale factor while it's cube gives the volume scale factor.

In this question, the linear scale factor will be 6/5

since we are asked to find the volume we cube the linear scale factor.

 (6/5)³=216/125

to get the volume of the larger prism we multiply the volume of the smaller by the V.S.L as shown

(216/125)×300in³= 518.4in³

Answer:

x =  [tex]2\sqrt{2}[/tex] (or [tex]\frac{2\sqrt{2} }{1}[/tex] if it needs to be represented as a rational denominator)

Step-by-step explanation:

We know that;

1.) This triangle is equilateral, and because of the line segment it's divided into 2 right triangles.

2.) The base of the whole triangle would be 4, and the base of the right triangle would be 2, since the base is cut in half with a mid point.

Therefore we can say;

A² + B² = C²

x² + 2² = 4²

x² + 4 = 16

x² = 16 - 4

x² = 8

x = [tex]\sqrt{8}[/tex]

Simplifying this further would be;

[tex]\sqrt{8}[/tex] = [tex]\sqrt{4} * \sqrt{2}[/tex]

[tex]\sqrt{8}[/tex] = [tex]2\sqrt{2}[/tex] (or [tex]\frac{2\sqrt{2} }{1}[/tex] if it needs to be represented as a rational denominator)

Answer:

50 muffins

Step-by-step explanation:

20 : 40%

y : 100%

[tex]\frac{20}{y} :\frac{40}{100}[/tex]

y · 40 = 20 · 100

40y = 2000

40y ÷ 40 = 2000 ÷ 40

y = 50

Answer:

50

Step-by-step explanation:

first you must find out how many muffins are in 1%, that will be .5 muffins which also meens that every 2% there will be 1 muffin. so we do 100 dived by 2 and you will get 50 which is the amount of muffins that will be made

Answer:

y = 5x - 13

Step-by-step explanation:

point slope form: y - y1 = m (x - x1)

plug in: y1 = -3,  x1 = 2,  m = 5

y - (-3) = 5 (x - 2)

y + 3 = 5x - 10                                     <- simplify and expand

y = 5x - 13                                    <answer for slope intercept

Answer:

y = 1/6x -4

Step-by-step explanation:

First find the slope

m= ( y2-y1)/(x2-x1)

m=(-5 - -3)/( -6 -6)

   = (-5+3)/ (-6-6)

       = -2/-12

       = 1/6

The slope intercept form is

y= mx+b where m is the slope and b is the y intercept

y = 1/6 x +b

Substitute a point into the equation

-5 = 1/6(-6) +b

-5 = -1+b

Add 1 to each side

-4 = b

y = 1/6x -4

Answer:

y=1/6x-4

Answer:

40217.6 cubic feet

Step-by-step explanation:

Given data

Diameter= 40feet

Radius= 20feet

Height=32feet

The expression for the volume is given as

V= πr^2h

Substitute

V= 3.142*20^2*32

V= 3.142*400*32

V=40217.6 cubic feet

Hence the volume of the tank is 40217.6 cubic feet

Answer:

I believe the slope would be -2

Step-by-step explanation:

The line goes down 2 boxes and over 1 box before it intersects with another point.  Knowing slope = [tex]\frac{rise}{run}[/tex], we know that slope = [tex]\frac{-2}{1}[/tex] which is equal to -2.

Answer:

probably √125

Step-by-step explanation:

so x is between 10.9 and 11.1

What i did was added those to together and then divided them by 2 so that i could find the average between them:

10.9 + 11.1 = 22

22/2=11

so you have 11 as your average.

now what i did was find the value of each answer choice to see which one was closest to 11 and the square root of 125 is just that.

The best approximation of decimals 10.9 and 11.1 is 11.

In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

Given that, location of x in number line

x = 10.9 and x = 11.1

Now, to estimate the value we will round up both digits and find the average.

In 10.9 round up to 11 and 11.1 will round down to 11

Now average = (11 +11)/2 = 11

Therefore, the best approximation of decimals 10.9 and 11.1 is 11.

using Pythagoras theoram

x²+4²=7²

x²= 49-16

x²= 33

x=√33

Answer:

See explanation

Step-by-step explanation:

Let

x = number of messages Salma sent

x + 9 = number of messages Brian sent

2(x + 9) = number of messages Chang sent

Total messages sent = 55

x + (x + 9) + 2(x + 9) = 55

x + x + 9 + 2x + 18 = 55

4x + 27 = 55

4x = 55 - 27

4x = 28

x = 28/4

x = 7

Number of messages Salma sent = x = 7 messages

Number of messages Brian sent = x + 9

= 7 + 9

= 16 messages

Number of messages Chang sent = 2(x + 9)

= 2(7 + 9)

= 2(16)

= 32 messages
