Answer:
4/5
Step-by-step explanation:
the mean is the average, so add all the numbers together and divide the sum by the amount of numbers.
1 1/3 + 1/4 + 2/3 + 1/2 + 1 1/4 =4
4÷5 = 4/5

The graph shows how the velocity v in centimeters per second of a fluid flowing in a pipe varies according to the radius r of the pipe.
Find the velocity of the fluid when the radius is 3 cm.
When the radius of the pipe is 3 cm, the velocity of the fluid in the pipe is ________ cm/s
Answer:
27 cm/s
Step-by-step explanation:
The x-axis is labelled as radius (r). Since the question is asking you to find the velocity of the fluid, which is labelled on the y-axis, you simply need to move along the x-axis until you reach 3 cm and move upwards until you've reached the line. Once you have reached the line, the answer should be on the y-axis which is 27 cm/s.
*x-axis is along the bottom and y-axis is vertical along the left side.*

Hi! I hope you're enjoying your day!
The missing number is 5.
Why 5? You'll see...
So the equation is
5x+15=5x-3
Is this right? We need to check.
Let's plug in 1.
5(1)+15=5(1)-3
5+15=5-3
20=-2
See? We ended up with a false statement.
There's no way 20 is going to equal -2.
Let's try 2:
5(2)+15=5(2)-3
10+15=10-3
25=7
Once again, we have a false statement.
You could try any number. You could try 5, 12, 150, 2710...
No matter which number you choose, you will always have a false statement.
Hence, the missing number is
[tex]\boxed{\boxed{\bold{5}}}[/tex]
But hey!! Why 5?!
Because no matter which number you pick, you will always have a false statement.
There's no number that can satisfy the following equation:
5x+15=5x-3
Basically, you take a number x, multiply it times 5, add 15, and that's supposed to equal the same number times 5 and minus 3?!
Hope everything is clear.
If you have any questions, please ask.

Answer:
Jeff. 130cm^3 more.
Step-by-step explanation:
Length · Width · Height = Volume
LWH = V
-----------------------------------------------------
Jeff's Popcorn Container:
[tex]20.5 * 10 = 205\\205 * 10 = 2050[/tex]
Jeff's popcorn container is a total volume [tex]2050cm^{3}[/tex].
-------------------------------------------------------
George's Popcorn Container:
[tex]30 * 8 = 240\\240 * 8 = 1920[/tex]
George's popcorn container is a total volume of [tex]1920cm^{3}[/tex].
--------------------------------------------------------
Now subtract George's popcorn container volume from Jeff's popcorn container volume.
[tex]Jeff - George = Total\\2050 - 1920 = 130[/tex]
And there you have it! Your answer is 130cm^3!
I hope this helped!

A regular hexagon is divided into six congruent equilateral triangles. If the perimeter of one of the triangles is 39 inches, what is the perimeter of the regular hexagon, in inches?
Answer:
Perimeter_hexagon
= 78 inches
Step-by-step explanation:
"Regular hexagon" means the shape has 6 sides and all the sides are the SAME length.
"equilateral triangles" means the triangles all three sides are the same.
"perimeter" is distance around the outside of a shape.
see image.
So if the triangle has perimeter 39 inches. We divide to find the length of a side.
39/3
= 13.
The side of the triangle is also the side of the hexagon.
Perimeter of the hexagon is
P = 6•side
P = 6•13
P = 78
see image.

In the diagram below, every pair of segments which do not intersect are parallel, and the measure of angle k is 89 degrees. What is the total number of degrees in angles s,e,q,u,o,i,a?
Answer:
633°
Step-by-step explanation:
Angles:
s = o = 89°
e = q = u = i = a = 91°
two angles of 89° and 5 angles of 91°
Total number
89(2) + 91(5) = 178+ 455 = 633°

Regular pentagon ABCDE and regular hexagon AEFGHI are drawn on opposite sides of line segment AE such that they are coplanar. What is the degree measure of exterior angle DEF?
Answer:
144 degrees
Step-by-step explanation:
The exterior angle of a pentagon is 72 degrees(interior angle is 108) add 90 if you want the full angle, so DEF is 144 degrees because 72*2.

The palm of the hand has about 500 sweat glands per 1 cm2. How many sweat glands would there be on a palm measuring 7 cm by 8 cm? explain in 10 sentances
Answer:
There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.
Step-by-step explanation:
We assume the palm has the shape of a rectangle.
The area of a rectangle is length × width.
The area of a palm measuring 7 cm by 8 cm is:
length × width = 7 cm × 8 cm = 56 cm²
Since 1 cm² has 500 sweat glands, 56 cm² has 56 times as many sweat glands.
500 × 56 = 28,000
Answer: There are 28,000 sweat glands on a hand measuring 7 cm by 8 cm.

Triangle HIJ has vertices H(1, 7) , I(−4, −2) , and J(−3, 5) . Write the coordinate notation for a translation of 3 units right and 4 units up.
(x, y)→
Step-by-step explanation:
(x, y) -> (x+3, y+4)
that is what 3 units to the right (3 units into the outsource x direction) and 4 units up (4 units into the posits y directing) mean.
so, all points go through this translation
(1, 7) -> (4, 11)
(-4, -2) -> (-1, 2)
(-3, 5) -> (0, 9)

1) Find the value of x. Round to the nearest tenth, if necessary. x = _______
Answer:
x = 34
Step-by-step explanation:
By Pythagoras theorem:
[tex] {x}^{2} = {(16)}^{2} + {(30)}^{2} \\ \\ = 256 + 900 \\ \\ = 1156 \\ \\ \implies \: x = \sqrt{1156} \\ \\ \implies \: x =34[/tex]
Answer:
x = 34 cm
Step-by-step explanation:
Using Pythagorean Theorem,
a² + b² = c²
Values given :-
a and b = 16 and 30
c = x
Substitute :-
x² = (16)² + (30)²
x² = 256 + 900
x² = 1156
x = √1156
x = 34 cm

Step-by-step explanation:
The formula for volume in a rectangular prism is V = l x w x h
Plug in the numbers to solve the unknown length.
240 = l x 4 x 6
240 = 24l
l = 10
[MA}:
10
The explanation:
Length: 4
Height: 6
Missing: h
15 x 4 x 6 = 360
13 x 4 x 6 = 312
12 x 4 x 6 = 288
10 x 4 x 6 = 240
Multiply.
V = L x W x H
L x 4 x 6
240 - 24l
L = 10
10 x 4 x 6 = 240

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 4 more than times the length of the bottom of the triangle. The last side is 13 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?
Answer:
(5x)+(x+13)
Step-by-step explanation:
Side 1 is 4x
Side 2 is x+13
Side 3 is x
(4x) and (x) are like terms and can be combined
(x+13) must stay like this since the x is unknown.
Answer:
P = 3x + 17
Step-by-step explanation:
length = x, side = x + 4, side = x + 13
P = x + x + 4 + x + 13
P = 3x + 17

At a basketball game, a team made 57 successful shots. They were a combination of 1- and 2-point shots. The team scored 94 points in all. Write and solve a system of equations to find the number of each type of shot.
Answer:
The number of 1-point shots is 15 and the number of 2-point shots is 42
Step-by-step explanation: x ----> the number of 1-point shots
y ----> the number of 2-point shots
we know that
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The intersection point is (15,42)
therefore
The number of 1-point shots is 15 and the number of 2-point shots is 42
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8 people took the trip.

The perimeter of a polygon is the sum of its side lengths. A square is a polygon with four sides, all the same length. You can add up the side lengths, or you can take advantage of multiplication to do the repeated addition.
P = 4s
P = 4(5.3 m) = 21.2 m
