Answer:
The volume of the cone is:
112.6 cubic inches.Step-by-step explanation:
You should know that the volume of a straight circular cone is equal to:
Cone volume = (1/3) PI * r ^ 2 * hWhere:
r = radius.
h = height.
Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:
Circumference = PI * Diameter.When clearing you get:
Diameter = circumference / PIBy replacing the data you get:
Diameter = 15 inches / PI Diameter = 4.77 inches.Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:
Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in Cone volume = 112.581541 in^3 Cone volume = 112.6 in^3Answer:
112.8 in

aiden and 5 friends went out for chicken and soda. the total cost of the soda was $7. if each person paid $14, what was the total cost of the fried chicken
Answer:
63$...I think
Step-by-step explanation:
if there was 5 friends and each paid 14$ the total must have been 70$. However, since the soda was 7$, then if you take away 7$ from the total, then the chicken must have been 63$
I don't know, man. Math isn't really my strongest suit, but I hope this helps :D
Answer:
$77
Step-by-step explanation:
Each person paid $14
Aiden+5 friends= 6 people
$14×6= $84
total cost of soda was $7

Step 6: as the line on the line graph moves from left to right, the line falls.
step 7: (idk)
Answer:
See answer for Step 6 below.
Step 7: the slope is "-1/2" (negative 1/2)
Step-by-step explanation:
Step 6: A negative slope means that as the value of the coordinate "x" increases,the value of the coordinate "y" decreases, and the rate of change for points on the line is therefore negative. The line goes "DOWN" as you read the graph from left to right.
In order to calculate the slope, we can use the triangle defined by the points (0, 5), (4, 3) and (0, 3) as shown in the attached image:
Where the "run" is from 0 to 4 , that is: 4 - 0 = 4
and the rise is negative (from 5 to 3: that is 3 - 5 = -2
Therefore, the rise over the run becomes: -2 / 4 = -1/2
Consider the function: f(x) = 2x^2 - 1.5x - 5 and its graph.
If the graph of f(x) is:
(i) first translated 2 units in the positive x direction and 3 units in the positive y
direction
(ii) then, stretched vertically by a factor of 2
(iii) and then reflected across the x-axis
What is the resultant function in standard form and its graph?
Answer:
f(x) = -4x² + 19x - 18
Step-by-step explanation:
[tex]f(x) = 2x^2 - 1.5x - 5[/tex]
i) If it is translated 2 units in the positive x direction, therefore we use f(x-2)
[tex]y=f(x-2) = 2(x-2)^2 - 1.5(x-2) - 5\\y = 2(x^2-4x+4) - 1.5x+3 - 5\\y=2x^2-8x+8-1.5x+3-5\\y=2x^2-9.5x+6[/tex]
f(x) = 2x² - 9.5x + 6
If it is then translated 3 units in the positive y, we add 3 to the input function to get:
[tex]y=f(x)+3=2x^2-9.5x+6+3\\y = 2x^2-9.5x+9[/tex]
ii) stretched vertically by a factor of 2, we multiply the function by 2 to get:
[tex]y =2( 2x^2-9.5x+9) = 4x^2-19x+18\\y= 4x^2-19x+18[/tex]
iii) reflected across the x-axis
we multiply the parent function by –1, to get a reflection about the x-axis.
[tex]y= -1(4x^2-19x+18)=-4x^2+19x-18\\y=f(x)=-4x^2+19x-18[/tex]

Answer:
A. [tex]11 + 3\frac{5}{8}[/tex]
Step-by-step explanation:
Subtracting a positive number is like adding a negative number, as in you move to the left on a number line. A negative number is the opposite of the positive, so you move to the right instead, which is equivalent to adding.
Make sure there are parenthesis around the negative number, otherwise, you might be seeing one minus sign as two!

What is the exponential form of the following equation? logb3 = -8
assuming b is the underscript of log, the formula is log _b_3=-8.
the formula for log is usually log_b_x=n, and to convert it to exponential would be the same as b^n=x
just fill in the numbers, b is still b, and -8 will be the in place of n, equal to 3.
b^-8=3
If x varies directly as y, and x = 200 when y = 11, find y when x = 500. Please algebraic solution :) thanks!
Answer:
x ⠀⠀200⠀⠀ ⠀500
y⠀⠀⠀ 11⠀⠀⠀⠀⠀a
As x directly varies with y
200 × a = 500 × 11
a = 5/2 × 11 = 27.5
Answer:
y = 27.5
Step-by-step explanation:
We know that directly proportional equations usually come in the format of
y = k × x where 'k' is the constant. In this problem we are presented with a directly proportional questions asking us to find y when x= 500 considering that y varies directly with x and x = 200 when y = 11. So let's substitute in the values
→ y = k × x
⇒ Substitute in the first set of values which is x = 200 and y = 11
→ 11 = k × 200
⇒ Divide both sides by 200 to isolate 'k'
→ 0.055 = k
Now we know that the constant is 0.055 we can substitute the second set of values in,
→ y = 0.055 × x
⇒ Substitute in the second value which is x = 500
→ y = 0.055 × 500
⇒ Simplify
→ y = 27.5
If y varies directly with x and x = 200 and y = 11, the value of y when x = 500 is 27.5

A cardboard box is 18 feet long, 7 feet wide, and 6 inches high. What is the is closest to the volume of the box in cubic YARDS? 20 points
Answer:
The volume of the box is [tex]2.33\ \text{yards}^3[/tex].
Step-by-step explanation:
We have,
Length of a cardboard box is 18 feet
Width of cardboard box is 7 feet
Height of a cardboard box is 6 inches
The conversion from one units and another is as follows :
1 foot = 0.334 yards
18 feet = 6 yards
7 feet = 2.334 yards
1 inch = 0.0277 yards
6 inches = 0.1667 yards
Now,
Length, l = 6 yards
Width, b = 2.334 yards
Height, h = 0.1667 yards
The box in the form of cuboid. The volume of a cuboid shaped object is given by :
[tex]V=l\times b\times h[/tex]
Plugging all the values, we get :
[tex]V=6\times 2.334\times 0.1667\\\\V=2.33\ \text{yards}^3[/tex]
So, the volume of the box is [tex]2.33\ \text{yards}^3[/tex].

Choose the system of equations that matches the following graph:
3x + 4y = 24
3x + y = −3
3x + 4y = 24
3x − y = 3
3x − 4y = −24
3x + y = −3
3x − 4y = −24
3x − y = 3
One of the lines passes through points (0, 6) and (-4, 3). Hence the equation is given by:
(y - 6)/(x - 0) = (3 - 6)/(-4 - 0)
(y - 6)/x = -3/-4 = 3/4
4(y - 6) = 3x
4y - 24 = 3x
3x - 4y = -24
The other line passes through points (0, -3) and (1, 0). Hence the equation is given by:
(y - (-3))/(x - 0) = (0 - (-3))/(1 - 0)
(y + 3)/x = (0 + 3)/1
y + 3 = 3x
3x - y = 3
Therefore, the system of equations representing the graph is:
3x - 4y = -24
3x - y = 3

−5y+8x=−18
5y+2x=58
Solve the system of equations.
Answer:
1: −5y+8x=−18
Slope = 3.200/2.000 = 1.600
x-intercept = -18/8 = -9/4 = -2.25000
y-intercept = 18/5 = 3.60000
2: Slope = -0.800/2.000 = -0.400
x-intercept = 58/2 = 29
y-intercept = 58/5 = 11.60000
Step-by-step explanation:
1: Step 1 :
Equation of a Straight Line
1.1 Solve -5y+8x+18 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line -5y+8x+18 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 18/5 so this line "cuts" the y axis at y= 3.60000
y-intercept = 18/5 = 3.60000
Calculate the X-Intercept :
When y = 0 the value of x is -9/4 Our line therefore "cuts" the x axis at x=-2.25000
x-intercept = -18/8 = -9/4 = -2.25000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 3.600 and for x=2.000, the value of y is 6.800. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.800 - 3.600 = 3.200 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Need help!!! Answer asap!!
Answer:
Step-by-step explanation:
You must assume that N is the center of the circle.
NTP is a right triangle.
NM is the radius
NT is also a radius
The area of the circle is 25pi
25 pi = pi r^2
r^2 = 25
r = 5
The right angle triangle can be solved by
PT^2 + NT^2 = (r + 4)^2
PT^2 + 25 = (5+4)^2
PT^2 + 25 = 81
PT^2 = 56
PT = sqrt(56)
PT = 7.48
67 2 3 % of the animals at an animal shelter are dogs. About what fraction of the animals at the shelter are dogs?
Answer:
About 2/3 of the animals at the shelter are dogs
Step-by-step explanation:
Let's first transform the mixed number to the corresponding improper fraction.
67 2/3 is equivalent to (3*67 + 2)/3 = 203/3
we are asked to find a fraction equivalent to 203/3%. To do this, we have to divide the fraction by 10, as follows:
203/3% = (203/3)*(1/100) = 203/300 ≈ 2/3
