Answer:
4 feet
Step-by-step explanation:
Their is one rectangular prison divided into two.
The volume of the first one is
V1= L X H X W=80.
Volume of the second one is
V2= L X H X W
V2= 6 X H X 5
V2 = 30H
Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;
80+30H=200, collecting the like term we have, 30H=200-80.
30H=120, divide both side by 30
30H/30=120/30
H= 4feet.
Height is 4feet.

Use three different values of n to demonstrate that 2n + 3n is equivalent to 5n.
The three different values of n to demonstrate that 2n + 3n is equivalent to 5n are 1, 4 and 10.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 2n + 3n
On simplifying the equation , we get
A = 5n
when n = 1 , we get

The average number of chocolate chips in one ounce is 63 with a standard deviation of 1.8. Find the probability that a randomly selected ounce of chocolate chips will contain between 62 and 66 chocolate chips .
The probability that a randomly selected ounce of chocolate chips will contain between 62 and 66 chocolate chips is 0.6644.
How to find the probability that a randomly selected ounce of chocolate chips will contain between 62 and 66 chocolate chipsUsing the z-score formula to standardize the values and find the probability using a standard normal distribution table:
z1 = (62 - 63) / 1.8 = -0.56
z2 = (66 - 63) / 1.8 = 1.67
Using the standard normal distribution table, we find that the area to the left of z1 is 0.2881 and the area to the left of z2 is 0.9525.
Therefore, the probability that a randomly selected ounce of chocolate chips will contain between 62 and 66 chocolate chips is:
P(62 < x < 66) = P(z1 < z < z2) = P(z < z2) - P(z < z1)
= 0.9525 - 0.2881
= 0.6644

Determine whether the given ordered list of numbers is a solution of the the system of equations
It should be noted that to evaluate whether an organized array of numbers serves as a resolution for a combination of equations, one can apply this method.
How to explain the methodWrite down the arrangement of equations that you wish to evaluate the solution for. For illustration, let us say that we have this system:
2x + 3y = 7
x - y = 2
Inject the data from the orderly list into the equations. For example, if the ordered list is (x=1, y=3), then we have:
2(1) + 3(3) = 7
1 - 3 = -2
Verify whether the outcome of the equations are equivalent to the values in the ordered list. If they are, then the orderly list is a resolution of the arrangement of equations. On the other hand, if not, then it is not a solution.

x2+10x+=()2
step by step
The value of the expression x² + 10x, when x = 2 is 24.
In the expression x² + 10x, x represents a variable, which is a placeholder for a value that can change. We are given that x = 2, which means we substitute 2 for x in the expression:
x² + 10x = 2² + 10(2)
Here, 2² means 2 raised to the power of 2, which is 2 multiplied by itself: 2² = 2 x 2 = 4.
10(2) means 10 multiplied by 2, which is 20.
So we can substitute these values in the expression:
x² + 10x = 2² + 10(2)
= 4 + 20
= 24
Therefore, when x is equal to 2, the value of the expression x² + 10x is 24.

-Calcula la primera derivada de la función (Método de Richardson).
F(X)= X4 + 3X2 +2
en X=2 h=0.01
The first derivative of the function f(x) = x^4 + 3x^2 + 2 at x=2 using Richardson's method with h=0.01 is approximately 33.8933.
To calculate the first derivative of the function f(x) = x^4 + 3x^2 + 2 using Richardson's method, we need to first calculate the approximate values of the function at x=2 and x=2+h, where h=0.01.
So, we have:
f(2) = 2^4 + 3(2^2) + 2 = 24
f(2+h) = (2+h)^4 + 3(2+h)^2 + 2
= 16 + 32h + 24h^2 + 8h^3 + h^4 + 12 + 12h + 3h^2 + 2
= h^4 + 8h^3 + 24h^2 + 35h + 30
Now, we can use Richardson's extrapolation formula to calculate the first derivative of the function at x=2:
f'(2) ≈ (4f(2+h) - f(2)) / (3h)
Substituting in the values we have:
f'(2) ≈ (4(h^4 + 8h^3 + 24h^2 + 35h + 30) - 24) / (3h)
= (4h^4 + 32h^3 + 96h^2 + 140h + 96) / (3h)
= (4h^3 + 32h^2 + 96h + 140) / 3
Now, we can substitute h=0.01 to get the value of the first derivative at x=2:
f'(2) ≈ (4(0.01^3) + 32(0.01^2) + 96(0.01) + 140) / 3
≈ (4(0.000001) + 32(0.0001) + 0.96 + 140) / 3
≈ (0.000004 + 0.0032 + 0.96 + 140) / 3
≈ 140.9632 / 3
≈ 33.8933
Therefore, the first derivative of the function f(x) = x^4 + 3x^2 + 2 at x=2 using Richardson's method with h=0.01 is approximately 33.8933.

So if the 3 interior angles are A, B, and C we have.
A + B + C = 180°
In this case we know that two of the angles are of 90°, so let's say that:
A = 90°
B = 90°
Replacing that we will get:
