volume of a pyramid = length x width x height
3
because a square has the same length and width, length = width = side
volume of a pyramid = side x side x height
3
volume of a pyramid = side² x height
3
We know the volume of the pyramid is 120 cubic meters, and the height is 10 meters, so:
120 = side² x 10
3
multiply both sides by 3
360 = side² x 10
divide both sides by 10
36 = side²
square root both sides
6 = side
A side length of the base is 6 meters.
Terry's house is 32 feet wide and the peak of the roof line is at 24 feet. write the absolute value equation to model the roof line
The peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:
y = |x - 16| + 24
This equation models the roof line of Terry's house.
To model the roof line of Terry's house, we can use the concept of absolute value. The equation for an absolute value function can be written as:
y = |x - h| + k
where (h, k) represents the vertex of the absolute value graph.
In this case, the peak of the roof line is at 24 feet. Since the width of the house is 32 feet, the vertex of the absolute value graph will be at the midpoint of the width, which is 16 feet. Therefore, h = 16.
Since the peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:
y = |x - 16| + 24
This equation models the roof line of Terry's house.

The systolic blood pressure for a certain group of people follows a normal distribution with = 120 and = 5.
What is the probability that a randomly selected person from the group will have a systolic blood pressure below 112?
The probability that a randomly selected person from the group will have a systolic blood pressure below 112 is 0.0548.
To find the probability that a randomly selected person from the group will have a systolic blood pressure below 112, we need to standardize the variable using the z-score formula:
z = (x - μ) /σ
where x is the value, we want to find the probability for, μ is the mean of the distribution, and σ is the standard deviation.
For this problem, we have:
z = (112 - 120) / 5 = -1.6
Now, we need to find the probability that Z (the standardized variable) is less than -1.6. We can do this by using a standard normal distribution table.
Using a standard normal distribution table, we find that the probability of Z being less than -1.6 is approximately 0.0548.
Therefore, the probability that a randomly selected person from the group will have a systolic blood pressure below 112 is approximately 0.0548 or 5.48%.

the cost of 4 beds and 3 wardrobes is $6,950 . of the bed costs $250 more than the wardrobe, find the cost of a bed
the cost of a wardrobe is approximately $850. Since the bed costs $250 more than the wardrobe, the cost of a bed would be approximately $850 + $250 = $1,100.
Let's assume the cost of a wardrobe is x dollars. Since the bed costs $250 more than the wardrobe, the cost of a bed would be x + $250.
According to the given information, the total cost of 4 beds and 3 wardrobes is $6,950. We can set up an equation to represent this:
4 * (x + $250) + 3 * x = $6,950
Simplifying the equation:
4x + $1,000 + 3x = $6,950
Combining like terms:
7x + $1,000 = $6,950
Subtracting $1,000 from both sides:
7x = $5,950
Dividing both sides by 7:
x ≈ $850
Therefore, the cost of a wardrobe is approximately $850. Since the bed costs $250 more than the wardrobe, the cost of a bed would be approximately $850 + $250 = $1,100.

Boxes of tea are packed into cartons. Each box is cube shaped with an edge of 2 cm. A carton measures 56 cm by 30 cm by 36 cm. Work out the number of boxes that will fill one carton.
Since each of the box is a cube, we use the formula for volume of a cube, which is a^3 [edge of the cube raised to the power 3] = (2)^3 = 8 cm^3 [2x2x2]
Now, the volume of the carton can be calculated using the formula length x breadth x height = 56 x 30 x 36 = 60,480 cm^3
Remember, all the units of the dimensions should be same and the final unit will be cm^3
The number of boxes of tea that can fit into the carton can be calculated by using the following formula: volume of the carton/volume of one tea box
= 60480/8
So, 7560 boxes of tea will fit in the carton

Find the indicated partial derivative.
f(x, y) = y sin−1(xy); fy(3,1/6).
fy(3,1/6)=_______
The required value of partial derivative of the given function is,
fy(3,1/6) ≈ 1.607.
To find fy,
We have to take the partial derivative of f with respect to y while holding x constant.
Using the chain rule, we have,
⇒ f(x, y) = y sin⁻¹(xy)
⇒ ∂f/∂y = sin⁻¹(xy) + y d/dy[sin⁻¹(xy)]
= sin⁻¹(xy) + y / √(1 - (xy)²) x
So, to find fy(3,1/6),
Substitute x = 3 and y = 1/6,
⇒ fy(3,1/6) = sin⁻¹(3/6) + (1/6) / √(1 - (3/6)²) x 3
= sin⁻¹(1/2) + 1/2

6. Florine borrowed $25 000 at
9.6% per year compounded monthly to
buy a new houseboat. She can repay the
money by making equal monthly
payments for 7 years or 10 years.
a) Determine the monthly payment for
each time period.
b) How much would Florine save in
interest by choosing the 7-year loan?
c) Why might Florine choose the 10-year
loan even though the interest costs are
greater?
a) The monthly payment for the 7-year loan would be approximately $406.37, and for the 10-year loan, it would be approximately $282.16.
b) By choosing the 7-year loan, Florine would save approximately $9,298.32 in interest compared to the 10-year loan.
c) Florine might choose the 10-year loan because the lower monthly payments fit better within her budget, even though it results in higher overall interest costs.
To calculate the monthly payment for each time period and determine the interest savings, we can use the formula for calculating the monthly payment on a loan:
\(P = \(\frac{{r(PV)}}{{1 - (1 + r)^{-n}}}\)\)
Where:
P = monthly payment
PV = present value (loan amount)
r = monthly interest rate (annual interest rate divided by 12)
n = total number of months
a) Monthly payment for the 7-year loan:
PV = $25,000
r = 9.6% per year / 12 months = 0.96% per month
n = 7 years * 12 months per year = 84 months
Using the formula:
\(P = \(\frac{{0.0096(25000)}}{{1 - (1 + 0.0096)^{-84}}}\)\)
Calculating this value will give us the monthly payment for the 7-year loan.
b) Monthly payment for the 10-year loan:
PV = $25,000
r = 9.6% per year / 12 months = 0.96% per month
n = 10 years * 12 months per year = 120 months
Using the formula mentioned above, we can calculate the monthly payment for the 10-year loan.
c) Florine might choose the 10-year loan, even though the interest costs are greater, for the following reasons:
- Lower monthly payment: The 10-year loan will have a smaller monthly payment compared to the 7-year loan. This could make it more affordable for Florine on a monthly basis and give her more financial flexibility.
- Other financial obligations: Florine might have other financial obligations or expenses that require her to have a lower monthly payment. By choosing the 10-year loan, she can manage her cash flow better and meet her other financial needs.
- Investment opportunities: Florine might have other investment opportunities where she can earn a higher return on her money than the interest rate on the loan. By choosing the 10-year loan and investing the saved monthly payment difference, she can potentially earn more than the additional interest costs.
It's important to consider that these reasons are subjective and depend on Florine's individual circumstances and financial goals.

To calculate the molarity of a solution, we divide the number of moles of solute by the volume of the solution in liters.
In this case, we have 0.512 moles of NaCl dissolved in 0.24 L of solution. The molarity can be determined by dividing the number of moles by the volume in liters.
Molarity (M) is defined as the number of moles of solute per liter of solution. In this case, we have 0.512 moles of NaCl dissolved in 0.24 L of solution. To calculate the molarity, we divide the number of moles by the volume in liters:
Molarity (M) = moles of solute/volume of solution (in liters)
Molarity (M) = 0.512 moles / 0.24 L ≈ 2.133 M
Therefore, the molarity of the solution is approximately 2.133 M.
