Answer:
The cone has a volume of approximately 982.5 cubic centimetres.
* That answer sounds off to me, but I'm not sure. You might want to run through the logic yourself and see if you get the same results.
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and base radius. In other words:
[tex]v = \pi r^{2} \frac{h}{3}[/tex]
But before using that, we need to know the value of h, height. What we are instead given is the slant height, or the length from tip to edge.
We can use that slant height along with the base radius to get the cone height, as the three of them are the edges of a right triangle, with slant height being the hypotenuse.
To get the height then we can say
[tex]h = \sqrt{s^{2} - r^{2}}[/tex]
Where h is height, s is slant, and r is radius.
[tex]h = \sqrt{14.8^{2} - 14^{2} }[/tex]
[tex]h = \sqrt{219.04 - 196}[/tex]
[tex]h = \sqrt{23.04}[/tex]
[tex]h = 4.8[/tex]
A very squat cone indeed.
Now we can plug that and the radius into the actual cone equation:
[tex]v = \pi (14cm)^{2} \frac{4.8cm}{3}\\= \pi 196cm^2 * 1.6cm\\\approx 985.2 cm^3[/tex]

Explain how to determine if you have a direct variation or proportional relationship
given a graph
Answer:
straight line that passes through the origin
Step-by-step explanation:
Two variables are said to have a direct variation or proportional relationship if it can be represented by y = kx, where k is a constant.
Comparing this with the equation of a straight line y = mx + b, where m is the slope of the line and b is the y intercept (value of y when x = 0), We can tell if the say that the graph of a direct variation or proportional relationship is a straight line with no y intercept (b = 0, that is it passes through the origin).

Answer:
The length of [tex]\overline{AD}[/tex] is 20 inches
Step-by-step explanation:
The given parameters are;
Triangle ABC is similar to triangle DEC, therefore, we can write, ΔABC~ΔDEC
[tex]\overline{AC}[/tex] = 30 inches
[tex]\overline{BA}[/tex] = 18 inches
[tex]\overline{ED}[/tex] = 6 inches
By similar triangles formula, we have;
[tex]\overline{BA}[/tex]/[tex]\overline{ED}[/tex] = [tex]\overline{AC}[/tex]/[tex]\overline{DC}[/tex]
Substituting the known values gives;
18/6 = 30/[tex]\overline{DC}[/tex]
Therefore, [tex]\overline{DC}[/tex] = 30/(18/6) = 30/18 × 6 = 10
[tex]\overline{DC}[/tex] = 10
[tex]\overline{AD}[/tex] = [tex]\overline{AC}[/tex] - [tex]\overline{DC}[/tex] = 30 - 10 = 20
[tex]\overline{AD}[/tex] = 20 inches.

How many fluid ounces are in a gallon?
1 cup= 8 ounces
1 pint= 2 cups
1 quart=2pints
1 gallon= 4 quarts
Answer:
128 fluid ounces
Step-by-step explanation:
As per linear equation, there are 128 ounces of fluid in a gallon.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."
Given relations for any fluid is:
1 cup = 8 ounces
1 pint = 2 cups
1 quart = 2pints
1 gallon = 4 quarts
Therefore,
1 gallon
= 4 quarts
= 4 (2) pints
= 8 pints
= 8(2) cups
= 16 cups
= 16(8) ounces
= 128 ounces
Therefore, for any particular fluid 128 ounces equal to 1 gallon.

Two functions are shown below.
f(x) = 3x + 7
g(x) = 2x + 12
What is the value of x where the graphs of f(x) and g(x) intersect?
Answer:
x=5
Step-by-step explanation:
Ok so put them equal to each other
2x+12=3x+7
subtract 12 from both sides
2x=3x-5
subtract 3x from both sides
-x=-5
divide both sides by -1
x=5

There are 56 students in a school play. The ratio of boys to girls is 3:5. How many girls are in the school play?
Answer:
35 girls
Step-by-step explanation:
First add the ratios together ( 3+5) this will give you 8. Then divide the total number of students by 8, this will get you 7. Now multiply 7 to 3 and multiply 7 to 5. As the ratio of boy to girl is 3 to 5, to find how many girls are in the school play we multiply 7 to 5. This makes 35 girls.
If you want to check, 7 x 3 =21 boys and 7 x 5=35 girls. 35 +21= 56 (the total number of students).

The math teacher gives each student a map of the amusement park that uses a coordinate plane. The meeting location is at (0, 0) on the map. Each unit is 100 feet. The first ride that you want to try is located at the coordinates (0, 4). The next ride is located at (3, 0). If you walked in a straight line from the first ride to the second ride, how many feet would you travel?
Answer:
500 ft
Step-by-step explanation:
use this formula
The actual distance between first and second ride is 500 ft.
What is Distance Formula?The distance between two point P(a, b) and Q(c, d).
so, the distance PQ = √(c-a)² + (d- b)²
Given:
Starting point = (0,0)
First ride = (0,4)
Second ride = (3,0)
In map, each unit = 100 ft
Using the distance formula
d = √( 3-0)² + (0-4)²
d = √9+ 16
d= √25
d = 5 units
So, the distance between first ride and second ride in the map is 5 units.
and,1 units = 100 ft
5 units = 500 ft
Hence, the actual distance between first and second ride is 500 ft.

Solve using substitution and show your work:
-3x-3y=3
y=-5x-17
Answer:
Step-by-step explanation:
Isolate any variable, x or y, but since y has already been isolated, use y to solve for x.
Substitute y into the first equation -3x-3y=3
This equals -3x - 3 (-5x - 17) = 3
Distribute to get -3x + 15x + 51 = 3
Then bring like terms together. -3x + 15x = 3 - 51
12x = -48
Solve for x
x = -4
Substitute -4 for x in the equation: y = -5x - 17
y = − 5x − 17
y = (−5) (−4) − 17
y = 20 - 17
y = 3 ( Simplify both sides of the equation)
Answer:
x = − 4 and y = 3
