Answer:

The correct option is V = one-third (6) (4) (8).

Step-by-step explanation:

The volume of a rectangular pyramid is:

V=\frac{1}{3}\ l\times b\times h

Here,

V = volume

l = length

b = base

h = height

The information provided is:

l = 6 inches

b = 4 inches

h = 8 inches.

Compute the equation of the volume of a rectangular pyramid as follows:

V=\frac{1}{3}\ l\times b\times h

   =\frac{1}{3}\times 6\times 4\times 8

Thus, the correct option is V = one-third (6) (4) (8).

In the following equations a and b are equal. which number could be substituted for both a and b to make both equations correct?
Nikitich [7]
 Considering the first equation 15 × 0 = -36 + a 
 15 × 0 = 0
therefore, -36 + a =0
In the second equation
 24 × 8 × 0 = 36 - b
Consider the LS 
24 × 8 × 0 = 0
Therefore, 36 - b = 0
we are left with the two equations,
 36 - b = 0
-36 + a = 0
then, we calculate the number that can be substituted to satisfy the two equations.
solving the equations
 b = 36, and a = 36
Therefore, 36 is the number that can be used to substitute a and b in the equations

Help out here asap the last it says how many units wide is the rectangle​
Marat540 [252]

Answer:

5m^5n^4

Step-by-step explanation:

Divide the length (5m^4n^2) into the area (25m^9n^6) to obtain the width:

25m^9n^6

----------------- = 5 m^(9-4)n(6-2)  = 5 m^5n^4

 5 m^4n^2

The width of the rectangle is 5m^5n^4.

I need help to solve this and also Hearn will the bacteria be over 100,000
lapo4ka [179]

Hello! Let's look at the two parts of this question.

Complete the table:

In this case, you just substitute the value of "hour" into the equation, for the value of t. For example:

P(0) = 120 (2)^{0}

P(0) = 120 (1)

P(0) = 120

Therefore, the number of bacteria for hour 0 is 120.

You can do this for the next ones. Hour 1 = 240, hour 2 = 480, and so on. (In this case, you can keep multiplying by 2)

Estimate when there will be more than 100,000 bacteria:

Set the final value of P(t) = 100,000, then solve.

100,000 = 120 (2)^{t}

833.33 = (2)^{t}

t = log_{2}833.33

t = 9.702744108

So your answer would be around 9.7 years, or, around 10 years.

Hope this helps!
