Answer:
The volume of the pyramid is 867 inch^3
Step-by-step explanation:
Here in this question, we are interested in calculating the volume of a square based pyramid.
Mathematically, we can use the formula below to calculate the volume V of a square based pyramid.
V = a^2h/3
where a represents the length of the side of the square and h is the height of the pyramid
From the question, the length of the side of the square is 17 in while the height is 9 in
Plugging these values, we have ;
V = (17^2 * 9)/3 = 17^2 * 3 = 867 cubic inch

Hi there!
[tex]\large\boxed{AC \approx 483 ft}}[/tex]
AC is the hypotenuse, so we can use a trig formula to solve.
We are given the adjacent side, AB, so we must use cosine. Recall that:
cosθ = A/H
Thus:
cos(21.3) = 450 / H
Rearrange:
H = 450 / cos(21.3)
Use a calculator to evaluate:
H = 482.99 ≈ 483 ft.
Answer:
AC ≈ 483
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos21.3° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{450}{AC}[/tex] ( multiply both sides by AC )
AC × cos21.3° = 450 ( divide both sides by cos21.3° )
AC = [tex]\frac{450}{cos21.3}[/tex] ≈ 483 ( to the nearest whole number )

After 4 years eldi will be three times the age he had 10 years ago. Using algebra find the age of eldi
Suppose that Eldi has x years old now :
x + 4 = 3 × ( x - 10 )
x + 4 = 3x - 30
Add both sides 30
x + 4 + 30 = 3x - 30 + 30
x + 34 = 3x
Subtract both sides x
x - x + 34 = 3x - x
34 = 2x
2x = 34
Divide both sides by 2
2x ÷ 2 =34 ÷ 2
x = 17
_____________________________
Thus Eldi is 17 .

Step-by-step explanation:
The secants exterior angle theorem states that when two secants (lines that intersect a circle at two points) intersect each other outside of the circle, then the absolute value of the difference divided by (2) equals the angle formed by the intersection of the two secants. One can apply this theorem here by stating the following, call the measure of the unknown arc (y);
[tex]\frac{30-y}{2}=10[/tex]
Solve for (y) with inverse operations:
[tex]\frac{30-y}{2}=10\\\\30-y=20\\\\y = 10[/tex]
When there is a diameter in a circle, the degree measure of the arc surrounding the diameter is (180). One can apply this here by stating the following:
[tex]30 + x + 10 = 180[/tex]
Simplify,
[tex]40 + x = 180[/tex]
Inverse operations,
[tex]40+x=180\\\\x = 140[/tex]
i thought of a number my number doubled is 20 greater than 200 what is my number
Answer:
Let the number be x.
x doubled is 2x, and 2x is 20 greater than 200. So, we have this:
2x = 200 + 20
2x = 220
x = 110.
Answer:
The unknown number is 110.
Step-by-step explanation:
Let the unknown number be n.
Then your number, doubled, is 200 + 20 (20 greater than 200), so the pertinent equation is 2n = 200 + 20, or 2n = 220.
Then n = 110.
Check: Is 2(110) = 200 + 20? Is 2(110) = 220? YES

A = 360 cm^2
Step-by-step explanation:
Using Pythagorean theorem, the length AB is given by
AB^2 = 17^2 - 8^2 = 225 cm^2
or
AB = 15 cm
Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm
so the length BD is
BD = BC + CD = 8cm + 16 cm = 24 cm
There the area of the rectangle is
A = AB×BD
= 15cm×24cm
= 360 cm^2

Make t the subject of the formula w = 3t + 11
Answer:
t = w/3-11/3
Step-by-step explanation:
w = 3t + 11
3t = w-11
t = 1/3(w-11
t = w/3-11/3

The graph of y = x2 + 11x + 24 is equivalent to the graph of which equation?
y = (x + 8)(x + 3)
y = (x + 4)(x + 6)
y = (x + 9)(x + 2)
y = (x + 7)(x + 4)
Answer:
y = (x+8)(x+3)
Step-by-step explanation:
The equivalent expression to the given quadratic equation is:
y = (x + 8)*(x + 3).
Which equation is equivalent to the given one?Here we start with:
[tex]y = x^2 + 11x + 24[/tex]
To solve the problem, we need to find the roots of the quadratic equation, to do it, we will use the Bhaskara's formula:
[tex]x = \frac{-11 \pm \sqrt{11^2 - 4*24} }{2} \\\\x = \frac{-11 \pm 5 }{2}[/tex]
Then the two solutions are:
x = (-11 + 5)/2 = -3x = (-11 - 5)/2 = -8Meaning that we can write the cuadratic equation as:
y = (x + 3)*(x + 8).
So the correct option is the first one.

What is the radius of this circle of the circumference is 18pi cm?
Answer:
r=9cm
Step-by-step explanation:
C= 2pi r = 18 pi so
2r =18 so r = 18/2=9
Answer:
[tex]r=9[/tex]
Step-by-step explanation:
The equation to find the circumference of a circle when given the radius is the following,
[tex]C=r(\pi)(r)[/tex]
There (C) represents the circumference, (r) represents the radius, and ([tex]\pi[/tex]) represents the irrational numbers (3.1415...)
Substitute in the given values and backsolve for the radius,
[tex]18(\pi)=2(\pi)(r)[/tex]
Inverse operations,
[tex]18(\pi)=2(\pi)(r)[/tex]
[tex]9=r[/tex]
