The volume of the rectangular pyramid below is 56 units³. Find the value of x.
Height=7
Width=6
Length=x
Answers
The length of the rectangular pyramid is 4 units.
How to find the value of the length?For a rectangular pyramid of length L, width W, and height H, the volume is given by:
V = L*W*H/3
in this case we know that the volume is 56 cubic units, and that:
Height=7
Width=6
Length=x
Replacing all of that in the equation above we will get:
56 = x*6*7/3
56 = 14x
56/14 = x
4 = x

A line passes through the point (-3,4) and has a slope of -5. Find an equation of this line
Answers
Answer:
y = -5x - 11
Step-by-step explanation:
We are given that a line passes through the point (-3,4) and also has a slope of -5.
We want to write an equation of this line.
The equation of the line can be written in 3 different ways:
Slope-intercept form, which is written as y=mx+b, where m is the slope and b is the y intercept.Standard form, which is written as ax+by=c, where a, b, and c are free integer coefficients (but a and b cannot be 0, and a cannot be negative). Slope-point form, which is written as \(y-y_1=m(x-x_1)\), where m is the slope, and \((x_1, y_1)\) is a pointSince the question did not specify, any of these 3 options will be valid, however, the most common way to write the equation of the line is in slope-intercept form, so let's do it that way.
Because we are already given the value of the slope, we can immediately plug that into the equation.
Replace m with -5.
y = -5x + b
Now we need to find b.
As the equation passes through the point (-3, 4), we can use its values to help solve for b.
Substitute -3 as x and 4 as y.
4 = -5(-3) + b
Multiply
4 = 15 + b
Subtract 15 from both sides.
-11 = b
Substitute -11 as b in the equation.
y = -5x - 11

If he takes 40 minutes for the round trip, find the width of the pond. Also find the boy's average speed on the round trip. Express your answer as decimals to the nearest tenth.
Answers
Answer:
t1 = S / (15 + 2) time to cross with wind
t2 = S / (15 -2) time to cross against wind
t = t1 + t2 = S / 17 + S / 13 = 30 S / 221 = .136 S where t is in hours
S = .667 hrs / .136 hrs/mi = 4.90 mi

Find the inverse of A = 9, -2 -10, 7 , if it exists.
Answers
The inverse of matrix A, if it exists, is:
A^(-1) = [7/43, 2/43; 10/43, 9/43]
To find the inverse of a matrix A, we need to determine if the matrix is invertible by calculating its determinant. If the determinant is non-zero, then the matrix has an inverse.
Given the matrix A = [9, -2; -10, 7], we can calculate its determinant as follows:
det(A) = (9 * 7) - (-2 * -10)
= 63 - 20
= 43
Since the determinant is non-zero (43 ≠ 0), we can proceed to find the inverse of matrix A.
The formula to calculate the inverse of a 2x2 matrix is:
A^(-1) = (1/det(A)) * [d, -b; -c, a]
Plugging in the values from matrix A and the determinant, we have:
A^(-1) = (1/43) * [7, 2; 10, 9]
Simplifying further, we get:
A^(-1) = [7/43, 2/43; 10/43, 9/43].

A 1000 L tank now contains 240 L of water. How long will it take to fill the tank using a pump that pumps 25 L per minute
Answers
Answer:
30.4 minutes
Step-by-step explanation:
The tank already has 240L in it, so we need to fill 1000 - 240 = 760L of water.
Since the pump pumps 25L per minute, we can find how many minutes it takes to pump 760L.
760 / 25 = 30.4 minutes.
It will take 30.4 minutes to fill the tank completely.
What is an equation?Two or more expressions with an equal sign are defined as an equation.
Given that, The 1000 L tank contains 240 L of water, therefore, the free space in the tank is :
1000-240
= 760 L
The pump fills the tank at a rate of 25 L per minute.
Therefore, it can be represented as:
25 L = 1 minute
1 L = (1/25) minutes
760 L = (1/25)×760 minutes
760 L = 30.4 minutes.
Hence, it will take 30.4 minutes to fill the tank completely.

Assume that the traffic to the web site of Smiley’s People, Inc., which sells customized T-shirts, follows a normal distribution, with a mean of 4.42 million visitors per day and a standard deviation of 800,000 visitors per day.
(a) What is the probability that the web site has fewer than 5 million visitors in a single day? If needed, round your answer to four decimal digits.
(b) What is the probability that the web site has 3 million or more visitors in a single day? If needed, round your answer to four decimal digits.
(c) What is the probability that the web site has between 3 million and 4 million visitors in a single day? If needed, round your answer to four decimal digits.
(d) Assume that 85% of the time, the Smiley’s People web servers can handle the daily web traffic volume without purchasing additional server capacity. What is the amount of web traffic that will require Smiley’s People to purchase additional server capacity? If needed, round your answer to two decimal digits.
Answers
(a) To find the probability that the web site has fewer than 5 million visitors in a single day, we need to find the area under the normal curve to the left of 5 million.
z = (x - μ) / σ
z = (5,000,000 - 4,420,000) / 800,000
Using a z-score table or calculator, we find that the z-score is approximately 0.7257.
Now, we can find the probability by looking up the z-score in the standard normal distribution table (cumulative distribution function, CDF), or using a calculator:
P(X < 5,000,000) = P(Z < 0.7257) ≈ 0.7673
Therefore, the probability that the web site has fewer than 5 million visitors in a single day is approximately 0.7673.
(b) To find the probability that the web site has 3 million or more visitors in a single day, we need to find the area under the normal curve to the right of 3 million.
z = (x - μ) / σ
z = (3,000,000 - 4,420,000) / 800,000
Using the z-score table or calculator, we find that the z-score is approximately -1.775.
P(X ≥ 3,000,000) = P(Z ≥ -1.775)
Since the total area under the curve is 1, we can subtract the area to the left of -1.775 from 1:
P(X ≥ 3,000,000) = 1 - P(Z < -1.775)
Using the z-score table or calculator, we find P(Z < -1.775) ≈ 0.0384.
P(X ≥ 3,000,000) = 1 - 0.0384 ≈ 0.9616
Therefore, the probability that the web site has 3 million or more visitors in a single day is approximately 0.9616.
(c) To find the probability that the web site has between 3 million and 4 million visitors in a single day, we need to find the area under the normal curve between these two values.
We already calculated the z-score for 3 million visitors in part (b). Now, we'll calculate the z-score for 4 million visitors:
z1 = (3,000,000 - 4,420,000) / 800,000
z1 ≈ -1.775
z2 = (4,000,000 - 4,420,000) / 800,000
z2 ≈ -0.525
Using the z-score table or calculator, we find P(Z < -1.775) ≈ 0.0384 and P(Z < -0.525) ≈ 0.2995.
P(3,000,000 ≤ X ≤ 4,000,000) = P(-1.775 ≤ Z ≤ -0.525)
≈ P(Z < -0.525) - P(Z < -1.775)
≈ 0.2995 - 0.0384
Therefore, the probability that the web site has between 3 million and 4 million visitors in a single day is approximately 0.2611.
(d) To find the amount of web traffic that will require Smiley’s People to purchase additional server capacity, we need to find the value (x) such that 85%
