<u>Given</u>:

Given that the side length of the base of the square pyramid is 16 inches.

The height of the pyramid is 22.1 inches.

We need to determine the volume of the square pyramid.

<u>Volume of the square pyramid:</u>

The volume of the square pyramid can be determined using the formula,

V=\frac{1}{3}Bh

where B is the area of the base and h is the height of the pyramid.

Substituting B = (16 × 16) and h = 22.1, we get;

V=\frac{1}{3}(16 \times 16)(22.1)

V=\frac{1}{3}(256)(22.1)

V=\frac{1}{3}(5657.6)

V=1885.9

Thus, the volume of the pyramid is 1885.9 cubic inches.

Please help me asap help. The other two options are 6 2/8 and 6 1/4
Pavlova-9 [17]

Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

A common inhabitant of human intestines is the bacterium Escherichia coli. A cell of this bacterium in a nutrient-broth medium d
qwelly [4]

Answer:

Step-by-step explanation:

Given that,

Cells are divided into two cell every 20mins, this implies that the half-life is 20mins

Initial population growth is 60cells

Growth rate r?

Population growth is modeled as

P(t) = Po•exp(rt)

Where,

Po is the initial growth at t= 0

Po= 60

P(t) is population at any time t.

Since the population doubles every 20mins(⅓hr)

Then, P(⅓) = 2×60 =120

Then, P(t) = 120cells

So, applying the formula

P(t) = Po•exp(rt)

120 = 60•exp(⅓r)

120/60 = exp(r/3)

2 = exp(r/3)

Take In of both sides

In(2) = r/3

Cross multiply

r = 3In(2)

r = 2.079 /hour

The growth rate is 2.079/hour.

What is the measurement of x in the equation. 8x+5x+2x-11+6=180
34kurt

Answer:

x = 37/3 = 12.333

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  15x - 185  =   5 • (3x - 37)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    5   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    3x-37 = 0

Add  37  to both sides of the equation :

                     3x = 37

Divide both sides of the equation by 3:

                    x = 37/3 = 12.333

If the sum of 4040 consecutive integer numbers is 2020, find out the absolute difference between the first number and the last n
bearhunter [10]

Let x be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is x+4039, so our answer is \boxed{4039}.

For completeness, though, let's solve for the value of x that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term a_1, last term a_n, and n terms, is \frac{n(a_1+a_n)}{2}. Plugging in our known values gives us the equation \frac{4040(2x+4039)}{2}=2020, which simplifies to 2x+4039=1. Thus, x=-2019, so the 4040 consecutive integers are -2019,-2018,\dots,-1,0,1,\dots,2018,2019,2020. Notice how everything except the 2020 cancels out!
