The surface area of the right triangular pyramid is 435.5 square units.
What is a surface area of a triangle?
A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed. It implies that the internal angles of a triangle add up to 180 degrees. It is the polygon with the fewest sides.
Here, we have
Given: X = 13 units, Y = 11 units, and Z = 15 units
We have to determine the surface area of the right triangular pyramid.
Surface area = base area + 1/2 (perimeter × slant height)
A = xy + 1/2 (3x × z)
A = 13 × 11 + 1/2 (3× 13 × 15)
A = 143 + 292.5
A = 435.5 square units.
Hence, the surface area of the right triangular pyramid is 435.5 square units.

What is the difference between largest 8 digit number and smallest 7 digit number?.
The difference between the largest 8-digit number and the smallest 7-digit number is 98999999.
The aim is to find the smallest 7-digit and largest 8-digit numbers, and then we need to determine the difference between these two values.
Let's start by finding the smallest 7-digit number.
We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 therefore it can be used in the highest place value.
Thus, we can create the required 7-digit smallest number with 0 and 1.
Hence, the smallest 7-digit number is 1000000.
Now, we will discover the largest 8-digit number.
As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 8-digit number with the digit 9.
Thus, the largest 8-digit number is 99999999.
Now, find the difference between these two values.
So, we can determine the difference between the smallest 7-digit and the largest 8-digit numbers by subtracting the smallest from the largest.
Thus, we get,
⇒99999999−1000000
⇒98999999
Hence, 98999999 is the difference between the smallest 7-digit and the largest 8-digit numbers.

3. The circle is circumscribed by the pentagon as shown (not drawn to scale). If QZ = 10, IX = 9, XT = 9, UW = 17, and SU = 10, find the perimeter of the pentagon and show work.
The perimeter of the pentagon is 76 units. The solution is obtained using tangent to circle.
What is tangent to a circle?
A line that touches a circle only once is said to be tangent to it. A point to circle can only have one tangent.
In the figure, the circle is circumscribed by the pentagon.
We are given QZ = 10, YX = 9, WX = 9, UW = 17, and US = 10
VW = WX = 9 (tangent of circle)
So, VU = UW - VW
VU = 17-9= 8
Since, VU and UT are tangents of circle, therefore
UT = 8
US = UT + TS
⇒10 = 8 + TS
⇒TS = 2
Now, TS and SR being tangents, therefore
TS = SR = 2
Also, RQ and QZ are tangents, therefore
RQ = QZ = 10
Similarly, ZY and YX are tangents, therefore
ZY = YX= 9
Thus, Perimeter = SQ + QY + YW + WU + US
⇒Perimeter = SR+ RQ+ QZ+ ZY+ YX+ XW+ UW+ US
⇒Perimeter = 2+ 10+ 10+ 9+ 9+ 9+ 17+ 10
⇒Perimeter = 76 units
Hence, the perimeter of the pentagon is 76 units.

Answer:
A fruit bouquet artist charges $1.50 for each piece of fruit in a bouquet, x, plus an additional $17 for the basket and decorations. Customers receive free delivery when their order is over $40.
Step-by-step explanation:
$1.50 represents the cost of each piece of fruit, but we don't know how many fruits are included in the basket, so let x be the number of fruit. That total must be added to the cost of the basket.
If consumers receive free delivery for orders over $40, then 17+1.50x must be greater than $40.

For what value of k the following pair of linear equations has infinitely many solutions 10x 5y?.
The 2 equations will have infinitely many solutions if k equals 10.
Here we have
10x + 5y − (k−5) = 0 and 20x + 10y − k = 0
Since these 2 are already in the standard form
a₁x + b₁y + c₁ = 0
and
a₂x + b₂y + c₂ = 0
we don't have to make any changes to them
According to the law, an equation has infinitely many solutions if
a₁/a₂ = b₁/b₂ = c₁/c₂
here,
a₁ = 10, b₁ = 5, and c₁ = - k + 5
and,
a₂ = 20, b₂ = 10, and c₂ = - k
Hence, we get
10/20 = 5/10 = ( - k + 5)/(-k)
or, (k - 5)/k = 1/2
or, 2k - 10 = k
or, k = 10

The value for a in quadratic function a(x-1)²+3 is obtained as a = 2.
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
The vertex of the quadratic function is (1,3).
The line passes through the points (3,5).
The equation is in the form - a(x-1)²+3
It is known that the vertex form of a quadratic function is f(x) = a(x-h)² + k, where (h,k) is the vertex of the parabola.
So it can be written -
f(x) = a(x-1)² + 3
Substitute the value of (1,3).
f(1) = a(1-1)² + 3 = 3
And for the point (3,5) the equation will be -
f(3) = a(3-1)² + 3 = 5
Set up a system of equations -
a(1-1)² + 3 = 3
a(3-1)² + 3 = 5
Solving for a in these equations -
a = 2
Therefore, the value of a is obtained as 2.

Set up a ratio: 150/100 = 210/x, or your investment gave you a return of 36% of the 150 you invested.
How do I calculate rate of return?The investment's initial value is subtracted from its current value, which is then divided by the investment's original value to determine a simple rate of return.
The calculation is as follows in light of the facts above:
The entire sum should be

Find all values of p so that px^2 + 40x + 16 is a perfect square.
For a quadratic of the form px^2 + 40x + 16 to be a perfect square, it must be able to be written in the form (mx + n)^2 for some real numbers m and n.
Expanding (mx + n)^2 gives:
(mx + n)^2 = m^2x^2 + 2mnx + n^2
Comparing this to the given quadratic, we can see that:
m^2 = p
2mn = 40
n^2 = 16
Solving for m and n, we find that:
m = ±√p
n = ±4
Therefore, in order for the quadratic to be a perfect square, the square root of p must be rational, and the value of p must be one of the following:
p = 0, 1, 16
So the possible values of p that make the quadratic a perfect square are 0, 1, 16.

To solve for the meaning term, the numbers in the numerator and denominator must be manipulated to get the same ratio. To do this, the numerator and denominator of the first equation can be multiplied or divided by the same number to get the same ratio as the second equation. When the ratio is the same, the meaning term can be found by dividing the numerator of the second equation by the denominator of the first equation. For example, the equation 2:3 = N:21 can be solved by multiplying 3 and 21 by 2, giving 6:42 = N:42, which has the same ratio. The meaning term is then found by dividing 42 by 3, giving N = 14.

And standard deviation 3. 5 in considered and executed jet that seats 6 with a doorway height of 56. 4 in.
a)what percentage of adult men can fit through the door without bending?
b) what's a doorway height would allow 40% of men to fit without bending
Using the given information, we can calculate the z-score as z = (56.4 - 67.6) / 3.5, which gives us a z-score of -2.3. This means that 2.3 standard deviations below the mean of adult men's heights is the doorway height of 56.4 inches. Since the area under the normal curve from -∞ to -2.3 is 16%, this means that 84% of adult men can fit through the door without bending.
Using the given information and the desired percentage, we can calculate the z-score as z = (x - 67.6) / 3.5, where x is the doorway height. Solving for x, we get x = 57.6 inches. Therefore, a doorway height of 57.6 inches would allow 40% of adult men to fit through without bending.

Find the length BD and CD
Sorry don't have image
The length of BD and CD are 15 units and 20 units respectively
How to find the length BD and CD?By the Angle Bisector Theorem, we have:
BD/DC = AC/BC = 21/28
We can use the Pythagorean Theorem to find AC:
AC² + BC² = AB²
21² + 28² = AB²
AB = 35 units
Now we can use the Angle Bisector Theorem to find BD:
BD/DC = 21/28
BD + DC = AB
BD = (21/49) × AB
BD = (21/49) × 35
BD = 15 units
To find CD, we can use the fact that BD + DC = AB:
CD = AB - BD
CD = 35 - 15
CD = 20 units
Therefore, the length are BD = 15 and CD = 20 units.
