A square pryamid have a total surface area of 1,477,500ft² and need to find the slant length. The length is 750ft. Find the slant length.
A.) 610in
B.) 610ft
C.) 3,050ft
D.) 3,050in
Answers
Surface area = base area + 4 * (base side length * slant height)
In this case, the surface area of the pyramid is 1,477,500ft², the base area is 750ft * 750ft = 562,500ft², and the base side length is 750ft. Substituting these values into the formula gives:
1,477,500ft² = 562,500ft² + 4 * (750ft * slant height)
Solving for slant height gives:
slant height = (1,477,500ft² - 562,500ft²) / (4 * 750ft)
= 915,000ft² / 3,000ft
= 305ft
So, the slant length is 305ft. The correct answer is therefore C) 3,050ft.

What is the slope of the line that passes through the points (-4, -6) and (1, -6)? Write your answer in simplest form
Answers
The slope of the line that passes through the points (-4, -6) and (1, -6) is zero and hence the line is parallel to the x-axis.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.
We know slope(m) = (y₂ - y₁)/(x₂ - x₁).
Therefore, The slope of the line that passes through the points (-4, -6) and (1, -6) is,
m = (- 6 + 6)/(- 4 - 1).
m = - 0/5.
m = 0.
As the slope is equal to zero the line is parallel to the x-axis.

How to find the maximum allowable pipe thicknessThe maximum allowable pipe diameter is calculated by
finding the total thickness of pipe
= interior diameter + 2 * pipe thickness
= 0.49 + 2 * 0.005
= 0.49 + 0.01

Therefore , the solution of the given problem of median comes out to be
confidence interval = [ 51.708 , 64.558 ].
Define median.When a dataset is ordered, the median value is the one that appears exactly in the middle of the dataset. The difference between the lowest and highest 50% of data is a measure of central tendency or average. Depending on whether you have an odd or even number of data points, the procedures for determining the median , mode change.
Here,
(48, 51, 65, 71, 61, 45, 48, 72, 74, 66, 43, 47, 70, 66, 45) sample data; sample mean, x = 58.133; sample size, n = 15; standard deviation, s = 11.6;
Standard deviation equals sd/√(n)
where, n = sample size and sd = standard deviation
Margin of error is equal to t alpha/2 and the standard error is (11.6/√( (15)) = 2.995. (standard error)
where ta/2 is the t-table level of significance, alpha is 0.05 from the standard normal table, the two-tailed value of |t alpha/2| with n-1 = 14 d.f is 2.145, and the margin of error is 2.145 * 2.995, which equals 6.425. The confidence interval for this margin of error is [58.133 6.425] = [51.708, 64.558].
being that,
sample data: (48 , 51 , 65 , 71 , 61 , 45 , 48 , 72 , 74 , 66 , 43 , 47 , 70 , 66 , 45 )
sample mean, x =58.133
standard deviation, s =11.6
sample size, n =15
level of significance, alpha = 0.05
from standard normal table, two tailed value of |t alpha/2| with n-1 = 14 d.f is 2.145
we use CI = x ± t a/2 * (sd/ √((n))
where,
x = mean
sd = standard deviation
a = 1 - (confidence level/100)
ta/2 = t-table value
CI = confidence interval
confidence interval = [ 58.133 ± t a/2 ( 11.6/ sqrt ( 15) ]
= [ 58.133-(2.145 * 2.995) , 58.133+(2.145 * 2.995) ]
= [ 51.708 , 64.558 ]
Therefore , the solution of the given problem of median comes out to be
confidence interval = [ 51.708 , 64.558 ].

A quadratic equation in the variable x is of the form. ax2 + bx + c = 0, where a, b, c are real numbers and a ≠ 0. • Roots of a quadratic equation : A real number α is said to be a root of the. quadratic equation ax2 + bx + c = 0, if aα2 + bα + c = 0.
Given:
x^2-5x+c=7, the constant term c will be obtained using the formula:
c=(-b/2a)²
The quadratic equation in its generic form is:
ax^2 + bx + c
To complete squares we must add the following term:
(b / 2) ^ 2
The equation is:
ax^ 2 - 5x + k = 7
By completing squares we have:
x ^ 2 - 5x + (-5/2) ^ 2 = 7 + (-5/2) ^ 2
Rewriting:

Answers
The total amount that Latoya ended up paying for the machinery, was $ 13, 080 .96
The amount of interest that Latoya paid was $ 980.96
