A sample of bacteria was placed in a petri dish. The number of bacteria changes exponentially over time.
The graph describes the number of bacteria over time in hours).

Answer:

B: |8| + (-7)

Step-by-step explanation:

When you are looking for the distance between two numbers, always add. The distance between 8 and -7 is 15 (|8| = 8). If, for instance, the answer was negative, which it is now, just find the absolute value of -15 which equals 15. The answer is B.

Answer:

We found the factors and prime factorization of 27 and 45. The biggest common factor number is the GCF number. So the greatest common factor 27 and 45 is 9.

Step-by-step explanation:

9 is the common factor of both 27 and 45 cause 9 * 5 is 45 and 9*3 is 27

Answer:

To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume.

Answer:

w to the power of two, or w squared

Step-by-step explanation:

Yes, one way you can express w^2 verbally, is by saying w to the power of two. However, you can also express this by saying w squared.

Answer:

782

Step-by-step explanation:

y = -670 + 33(44)

y = -670 + 1452

y = 782

Step-by-step explanation:

Step 1:  Find y when x is 44

[tex]y = -670 + 33x[/tex]

[tex]y = -670 + 33(44)[/tex]

[tex]y = -670 + 1452[/tex]

[tex]y = 782[/tex]

Answer: [tex]? = 782[/tex]

y = 25x + 35

35 is the original amount or your y intercept

25x is the slope since it is how much your cost increases by every time you ski

Answer:

would it be c because you can get 14 from 7 and you cant get they other numbers from 7 so maybe?

Step-by-step explanation:

Answer:

This graph will help you.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Your answer would be x = -1.

We can find this by first expanding the brackets on both sides of the equation:

4x + 8 = 6x + 10

Now we can rearrange and solve for x:

4x + 8 = 6x + 10

- 4x

8 = 2x + 10

- 10

-2 = 2x

÷ 2

-1 = x

I hope this helps!

Answer:

x = - 1

Step-by-step explanation:

Given

4(x + 2) = 2(3x + 5) ← distribute parenthesis on both sides

4x + 8 = 6x + 10 ( subtract 6x from both sides )

- 2x + 8 = 10 ( subtract 8 from both sides )

- 2x = 2 ( divide both sides by - 2 )

x = - 1

Answer:

n

Step-by-step explanation:

Answer:

The two equations are;

For adults, T = W kg × 70 mL/kg ............Equation (1)

For children, T = W kg × 80 mL/kg.............Equation (2)

Step-by-step explanation:

We are told that

Blood volume = 70 mL/kg for adults

Blood volume = 80 mL/kg in children

Therefore, the total blood volume,T  of an adult of weight, W is given by the following relation;

T = W kg × 70 mL/kg ............Equation (1)

The total blood volume,T of a child of weight, W is given by the following relation;

T = W kg × 80 mL/kg.............Equation (2).

-177,856=15

Answer:

[tex]P(F/S)=0.216[/tex]

Step-by-step explanation:

Let's call F the event that the student is female and S the event that the student is senior.

So, we need to find the probability P(F/S) that a student is female given that  the student is a senior. P(F/S) is calculated as:

P(F/S) = P(F∩S)/P(S)

Then, the probability P(F∩S) that a student is female and senior is equal to 0.06

On the other hand, we can calculate the total number of students x using the following equation as:

[tex]\frac{646}{x}+\frac{229}{x}-0.06=1[/tex]

Where 646/x is the percentage of female students, 229/x is the percentage of senior students and 0.06 is the percentage of female seniors.

Then, solving for x we get that the number of students is 825.4719

Additionally, the probability P(S) that a student is a senior is equal to:

[tex]P=\frac{229}{825.47} =0.2774[/tex]

Because there are 825.47 students and 229 are senior.

So, P(F/S) is equal to:

[tex]P(F/S)=\frac{0.06}{0.2774}=0.216[/tex]

Answer:

60

Step-by-step explanation:

To find the perimeter, you have to add up all the sides, like you have done.

This is 12+12+12+12+12 which is the same as 12*5 which is 60!

Answer:

x=3

Step-by-step explanation:

try different values on the line! plug them in and you'll see that every x value is 3!

Answer:

x=3

Step-by-step explanation:

Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.
