A water cooler (shaped like a cylinder) can hold approximately 6,104 in^3 of water. If a cylindrical cup measures 3 inches in diameter and will be filled to a height of 3 inches, how many cups of water will you be able to fill from one water cooler? Use 3.14 for π.
Answer:
Step-by-step explanation:
35
Step-by-step explanation:
They told you that the mean is 7.
You know there are 5 numbers
Mean = (number 1 + number 2 + number 3 + number 4 + number 5) / 5 = 7
Sum = 7 x 5
= 35.
To fill one water cooler, we need 288 cups of water.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
Given that a cylindrical water cooler can hold approximately 6104 in cubic of water.
And cylindrical cup with the height of 3 inches and diameter of 3 inches.
So let r be the radius of cup is 3/2 = 1.5 inch.
And we know that the volume of cylinder is given below by the formula;
volume of cylinder = π r² h
So now the volume of cylindrical cup = (3.14) (1.5)² (3) = 21.195
That means one cup can only fill 21.195 cubic of water to the water cooler.
To find the how many cups can fill the water cooler,
we will divide the volume of water cooler by volume of cup.
That means, 6104 / 21.195 = 287.99
Approximating the value,
6104 / 21.195 = 288 cups of water.
Therefore the 288 cups of water can fill the water cooler.

The company fired all of its math people so they do not know how to calculate the size of the tube needed. Please calculate the surface area needed for the tube. Use 3.14 for pi. *
Answer:
[tex] A= 2\pi (3cm)^2 +1 2\pi (3cm)(10 cm)= 18 \pi + 60\pi = 78 \pi cm^2[/tex]
And replacing the value of [tex]\pi =3.14[/tex] we got:
[tex] A = 78*3.14 cm^2= 244.92 cm^2[/tex]
Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:
[tex] r = \frac{D}{2}= \frac{6cm}{2}= 3cm[/tex]
And the surface area for a cylinder is given by this formula:

Answer:
x = 2 , y = 6
Step-by-step explanation:
Solve the following system:
{3 x + 2 y = y + 12 | (equation 1)
4 y - 7 x = 10 | (equation 2)
Express the system in standard form:
{3 x + y = 12 | (equation 1)
-(7 x) + 4 y = 10 | (equation 2)
Swap equation 1 with equation 2:
{-(7 x) + 4 y = 10 | (equation 1)
3 x + y = 12 | (equation 2)
Add 3/7 × (equation 1) to equation 2:
{-(7 x) + 4 y = 10 | (equation 1)
0 x+(19 y)/7 = 114/7 | (equation 2)
Multiply equation 2 by 7/19:
{-(7 x) + 4 y = 10 | (equation 1)
0 x+y = 6 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{-(7 x)+0 y = -14 | (equation 1)
0 x+y = 6 | (equation 2)
Divide equation 1 by -7:
{x+0 y = 2 | (equation 1)

What is the surface area of the square pyramid?
144 square cm
196 square cm
225 square cm
369 square cm
Answer:
225
Step-by-step explanation:
first the square
9*9 = 81
then the triangle
a is 8
triangles are l*w/2 so 8*4.5/2
8*4.5 = 36/2 = 18
There are 8 of these triangles
18*8 is 144
144+81 = 225
The surface area of the square pyramid is approximately `196` square cm.
What is Surface Area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
We can use the Pythagorean theorem to find the slant height of the pyramid:
[tex]$$l = \sqrt{a^2 + \left(\frac{b}{2}\right)^2} \\= \sqrt{8^2 + \left(\frac{9}{2}\right)^2} \\= \sqrt{64+\frac{81}{4}} \\= \frac{\sqrt{433}}{2}$$[/tex]
So, the lateral area of the pyramid is the area of the four triangles with base `b` and height `l`, which is:
[tex]$$A_{lat} = 4\cdot\frac{1}{2}b\cdot l \\= 4\cdot\frac{1}{2}\cdot 9 \cdot \frac{\sqrt{433}}{2} \\= 27\sqrt{433}$$[/tex]
So, The area of the base of the pyramid is a² then
[tex]$$A = A_{lat} + a^2$$[/tex]
= = 27√433 + 8²
= 27√{433} + 64
= 196.4 cm²
Therefore, the surface area of the square pyramid is approximately `196` square cm.

P.s. working.
Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13

Mariska was comparing her options for investment. One choice she was looking at showed that her principal of $1,875 over 10 years would earn $1,125 in interest giving her a total of $3,000 at the end of the investment period. What interest rate is being used to calculate this investment?
Answer: 6%
Step-by-step explanation:
Principal= $1875
Time= 10 years
Interest= $1125
Rate = Unknown
Recall that,
Interest= (Principal×Rate×Time)/100
I = PRT/100
100I = PRT
R= (100×I)/PT
Rate = (100 × 1125)/(1875 × 10)
Rate = 112500/18750
Rate= 6%
The rate is 6%

Q1: Tyson is taking his basketball team to watch a college basketball game. He bought 8 tickets for $168 $ 168 . One parent bought her son's ticket separately and paid $24 $ 24 . Who had the better deal?
Answer:
Tyson had the better deal
Step-by-step explanation:
We simply want to know who paid less for the ticket.
Tyson bought 8 tickets for the members of his basketball team and it cost it $168 in total.
The cost of each ticket is therefore:
168 / 8 = $21
He paid $21 for each ticket.
The parent bought her son's ticket for $24.
Therefore, Tyson had the better deal because he paid $3 less than the woman.

Determinar un numero, que disminuido en sus 1/4 partes equivale a su duplo aumentado en 30. Una cuerda de 180m se corta en tres trozos: trozo A B Y C. Calcular cuantos miden los trozos sabiendo que el trozo B y el trozo C miden el doble y el triple que el trozo A, respectivamente.
Answer:
x = 240
A = 30 m, B = 60 m, C= 90 m
Step-by-step explanation:
a) Nosotros debemos determinar un numero;
para cual [tex]\dfrac{1}{4}x = 60[/tex]
[tex]0.25 x = 60[/tex]
Divide ambos lados entre 0.25; tenemos :
[tex]\dfrac{0.25 x}{0.25}= \dfrac{60}{0.25}[/tex]
x = 240
b) A 180 m se corta en tres piezas A, B y C
Entonces;
Si la pieza B y la pieza C miden el doble y el triple de esa pieza A, respectivamente. Entonces; tenemos
x + 2x + 3x = 180
6x = 180
Divide ambos lados entre 6; tenemos:
[tex]\dfrac{6x}{6} = \dfrac{180}{6}[/tex]
x = 30 m
Si A = x = 30 m
B = 2x = 2×30 m = 60 m
C = 3x = 3×30 m = 90 m
Así; A = 30 m, B = 60 m, C= 90 m

two integers that multiply to 18 and add to -11
Answer:
-9 and 2
Step-by-step explanation:
Which of the following statements is true for the logistic differential equation?
The graph has a horizontal asymptote at y = 18.
y is growing the fastest when y = 9.
The limiting value for y is 18.
All of the above.
Answer:
All of the above
Step-by-step explanation:
dy/dt = y/3 (18 − y)
0 = y/3 (18 − y)
y = 0 or 18
d²y/dt² = y/3 (-dy/dt) + (1/3 dy/dt) (18 − y)
d²y/dt² = dy/dt (-y/3 + 6 − y/3)
d²y/dt² = dy/dt (6 − 2y/3)
d²y/dt² = y/3 (18 − y) (6 − 2y/3)
0 = y/3 (18 − y) (6 − 2y/3)
y = 0, 9, 18
y" = 0 at y = 9 and changes signs from + to -, so y' is a maximum at y = 9.
y' and y" = 0 at y = 0 and y = 18, so those are both asymptotes / limiting values.
graph the circle x^2+y^2+2x+4y-44=0
plot the circle on a coordinate plane, with the center at (-1, -2) and a radius of 7 units.
To graph the equation of the circle x^2 + y^2 + 2x + 4y - 44 = 0, we can follow these steps:
1. Complete the square for the x-terms:
Rearrange the equation to group the x-terms together:
x^2 + 2x + y^2 + 4y = 44
To complete the square for the x-terms, add (2/2)^2 = 1 to both sides of the equation:
x^2 + 2x + 1 + y^2 + 4y = 44 + 1
Simplify:
(x + 1)^2 + y^2 + 4y = 45
2. Complete the square for the y-terms:
To complete the square for the y-terms, add (4/2)^2 = 4 to both sides of the equation:
(x + 1)^2 + y^2 + 4y + 4 = 45 + 4
Simplify:
(x + 1)^2 + (y + 2)^2 = 49
3. Identify the center and radius:
The equation is now in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2
Comparing this with our equation, we can see that the center of the circle is (-1, -2) and the radius is √49 = 7.
4. Plot the graph:
The center of the circle is (-1, -2), which represents the point where the circle is centered. From this point, we can draw a circle with a radius of 7 units in all directions.
By following these steps, we can plot the circle on a coordinate plane, with the center at (-1, -2) and a radius of 7 units.

2. 16π,
3. 2.45π,
4. ( About ) 5.56π,
5. 13.7π
6. ( About ) 1.78π
Step-by-step explanation:
1. Let us keep the answer in terms of π, for the simplicity;
Area of Circle ⇒ π * r^2 = π * ( 3 )^2 = 9π,
Degree measure of arc / Degree measure of circle = Area of sector / Area of Circle,
62 / 360 = Area of sector / 9π,
62 * ( 9π ) = 360 * Area of sector,
558π = 360 * Area of sector,
Area of sector; 1.55π
2. Area of Circle ⇒ π * r^2 = π * ( 8 )^2 = 64π,
Area of sector ⇒ 1 / 4 * 64π = 16π,
Area of sector; 16π
3. Area of Circle ⇒ π * r^2 = π * ( 3 )^2 = 9π,
Degree measure of arc / Degree measure of circle = Area of sector / Area of Circle,
98 / 360 = Area of sector / 9π,
98 * ( 9π ) = 360 * Area of sector,
882π = 360 * Area of sector,
Area of sector; 2.45π
4. Area of Circle ⇒ π * r^2 = π * ( 4 )^2 = 16π,
Degree measure of arc / Degree measure of circle = Area of sector / Area of Circle,
125 / 360 = Area of sector / 16π,
125 * ( 16π ) = 360 * Area of sector,
2000π = 360 * Area of sector,
Area of sector; ( About ) 5.56π
5. Area of Circle ⇒ π * r^2 = π * ( 6 )^2 = 36π,
Degree measure of arc / Degree measure of circle = Area of sector / Area of Circle,
137 / 360 = Area of sector / 36π,
137 * ( 36π ) = 360 * Area of sector,
4932π = 360 * Area of sector,
Area of sector; 13.7π
6. Area of Circle ⇒ π * r^2 = π * ( 2 )^2 = 4π,
Degree measure of arc / Degree measure of circle = Area of sector / Area of Circle,
160 / 360 = Area of sector / 4π,
160 * ( 4π ) = 360 * Area of sector,
640π = 360 * Area of sector,
Area of sector; ( About ) 1.78π
