A square pyramid is placed inside a cube having a volume of 729 in3. The pyramid has the same height as the cube and the base of the pyramid is one face of the cube. Which is the ratio of the volume of the pyramid to the volume of the cube?
a 1/9
b 1/2
c 1/3
d 2/3
Answer:
1/3
Step-by-step explanation:
pyramid height = cube height , a = h (GIVEN)
[tex]so, v= \frac{1}{3} * a^{2} * h = \frac{1}{3} * a^{3}\\a = \sqrt[3]{3v} = \sqrt[3]{3*729} = 13 in\\\\cube volume = a^{3} = 13^{3} = 2187 in^{3} \\\\ratio = \frac{729}{2187}= \frac{1}{3} (ANS)[/tex]
We could also represent this function with an equation, A = #r2. We say that the input of
the function, r, is the independent variable and the output of the function, A, is the
dependent variable. We can choose any value for r, and then the value of A depends on
the value of r. We could also represent this function with a table or as a graph. Depending
on the question we investigate, different representations have different advantages. You
may recognize this rule and know that the area of a circle depends on its radius.
Here is a task to try with your student:
Jada can buy peanuts for $0.20 per ounce and raisins for $0.25 per ounce. She has $12 to
spend on peanuts and raisins to make trail mix for her hiking group.
1. How much would 10 ounces of peanuts and 16 ounces of raisins cost? How much
money would Jada have left? 6
2. Using p for pounds of peanuts and r for pounds of raisins, an equation relating how
much of each they buy for a total of $12 is 0.2p+ 0.25r = 12. If Jada wants 20 ounces
of raisins, how many ounces of peanuts cán she afford? 7

'Do you need to break apart a solid figure in a certain way to find its volume? Use the problem above to explain your reasoning.'
Answer:
You do in some situations have to break apart a solid figure in a certain way to find it's volume. Everything is made up out of some type of shape. You just have to find the right formula. Some solid figures you might have a cube and a pyramid. Each one of those has it's specail way of finding volume.

Step-by-step explanation:
Find the missing length of the triangle. *
Answer:
50 ft
Step-by-step explanation:
This is the pythagorean theorem, so you should use the formula...
a squared + b squared = c squared
Then substitute in the numbers... (remember, a and b are the legs, and c is the hypotenuse)
14 squared + 48 squared = c squared
14 squared = 14 x 14 = 196
Now we have 196 + 48 squared = c squared
48 squared = 48 x 48 = 2,304
Now we have 196 + 2,304 = c squared
Add them together - 2,304 + 196 = 2,500
Now we have 2,500 = c squared
We find the square root of 2,500 which is 50
You should now have 50 = c
That is your answer. Don't forget to add units.
50 ft is your hypotenuse (c)
I hoped this helped
Answer: the missing length is 50
Step-by-step explanation:
in order to figure out the missing number, you have to do the pythagorean theorem, which is a²+b²=c². A is 14 ft, B is 48 ft, and C is the missing length. You have to square each number. 14 will be 196 and 48 would be 2304.

Determine the missing angle in a triangle.
Answer:
145
Step-by-step explanation:
The the that connects the outside line to the inside line will equal to 180 so you take 180 minus 137 to get 43 and you have two angles for the inside which is 43 and 102. You minus these two number to 180 to get the last missing angle in a triangle because the inside of a triangle is 180 and then minus 180 to 35(Last angle measure) to get the outside of the triangle and you get 145.
Answer:
?=145°
Step-by-step explanation:
The angle 137° is a supplementary angle. So subtract 137 from 180 to find the adjacent angle:
[tex]180-137=43[/tex]
The angle adjacent the angle 137° is 43°. Add this value to the angle measure in the triangle:
[tex]102+43=145[/tex]
Two angle measures within the triangle add up to 145°. The angle measures of a triangle should add up to 180°. Subtract:
[tex]180-145=35[/tex]
The third angle in the triangle is 35°. This angle is also a supplementary angle. Subtract this from 180 to find the measure of angle ?:
[tex]180-35=145[/tex]
The angle ? is 145°.
or
The outer angle of a triangle (angle ?) can be found by finding the sum of the two angles within a triangle, not including the adjacent angle (or ?'s supplementary angle). So find the measure adjacent 137°:
[tex]180-137=43[/tex]
Add the two inner angle measure together:
[tex]43+102=145[/tex]
So angle ? is 145°.

A box without a top is to be made from a rectangular piece of cardboard, with dimensions 9 in. by 10 in., by cutting out square corners with side length x and folding up the sides.
What is the optimal volume of the box, and what is the optimal cut?
Answer:
The optimal volume is 63.1142 in3, with a cut of 1.5767 inches
Step-by-step explanation:
If we make a cut of x inches to create the box, the dimensions of the box will be:
Length = 10 - 2x
Width = 9 - 2x
Height = x
So the volume of the box would be:
Volume = (10 - 2x) * (9 - 2x) * x
Volume = 4x3 - 38x2 + 90x
To find the maximum volume, we need to take the derivative of the volume and find the values of x where it is equal to zero:
dV/dx = 12x2 - 76x + 90 = 0
6x2 - 38x + 45 = 0
Using Bhaskara's formula, we have:
Delta = 38^2 - 4*6*45 = 364
sqrt(Delta) = 19.08
x1 = (38 + 19.08) / 12 = 4.7567
x2 = (38 - 19.08) / 12 = 1.5767
Testing these values in the volume equation, we have:
Volume1 = 4*(4.7567)^3 - 38*(4.7567)^2 + 90*(4.7567) = -1.1883
(Negative value for the volume is not valid)
Volume1 = 4*(1.5767)^3 - 38*(1.5767)^2 + 90*(1.5767) = 63.1142
So the optimal volume is 63.1142 in3, with a cut of 1.5767 inches

Answer:
g(x)=0.8x+1.6
Step-by-step explanation:
To do this, you need to isolate the variable y, so that when you input x it will immediately return the value of y.
[tex]-4x-6=-5y+2[/tex]
Subtract 2 from both sides:
[tex]-4x-8=-5y[/tex]
Divide both sides by -5:
[tex]y=0.8x+1.6\\\\g(x)=0.8x+1.6[/tex]
Hope this helps!
Answer:
g (x) = 4/5x + 8/5
Step-by-step explanation:
-4x - 6 = -5y + 2
5y = 4x + 8
y = 4/5x + 8/5

5. A) 16.2
6. A) 11.2
7. No, they do not form a right triangle
8. Yes, they do form a right triangle

Extra tip: The hypotenuse has to be less than both sides added together, but cannot be more than either of the sides alone.
1.
16² + b² = 17²
256 + b² = 289
256 - 256 + b² = 289 - 256
b² = 33
√b² = √33
b = 5.74 or 5.7
2.
16² + b² = 20²
256 + b² = 400
256 - 256 + b² = 400 - 256
b² = 144
√b² = √144
b = 12
3.
7² + 9² = c²
49 + 81 = c²
130 = c²
√130 = √c²
11.40 or 11.4 = c
4.
7² + b² = 9²
49 + b² = 81
49 - 49 + b² = 81 - 49
b² = 32
√b² = √32
b = 5.65 or 5.7
5.
a² + 5² = 17²
a² + 25 = 289
a² + 25 - 25 = 289 - 25
a² = 264
√a² = √264
a = 16.24 or 16.2
6.
10² + b² = 15²
100 + b² = 225
100 - 100 + b² = 225 - 100
b² = 125
√b² = √125
b = 11.18 or 11.2
7.
15² + 8² = 16²
225 + 64 = 256
289 ≠ 256
8.
5² + 12² = 13²
25 + 144 = 169
169 = 169

What is the equation of the parabola that has its vertex at (7,6) and contains the point (6,8)?
Answer:
[tex]y = 2 (x-7)^{2} +6[/tex] is the equation of parabola.
Step-by-step explanation:
Vertex form of a parabola is given as :
[tex]y = a (x-h)^{2} +k ...... (1)[/tex]
(h,k) is the co-ordinate of vertex of parabola.
(x,y) are the points on parabola.
We are given that vertex is at (7,6) and a point on parabola is (6,8).
h = 7
k = 6
x = 6 and
y =8
Putting all the values in equation (1):
[tex]8 = a (6-7)^{2} +6\\\Rightarrow 8 = a + 6\\\Rightarrow a = 2[/tex]
Putting values of (h,k) and a in equation (1) to obtain the equation of parabola:
[tex]y = 2 (x-7)^{2} +6[/tex] is the equation of parabola with vertex at (7,6) and contains the point (6,8).
