Step-by-step explanation:
To Find the Median do the following below;
Arrange data values from lowest to highest valueThe median is the data value in the middle of the setIf there are 2 data values in the middle the median is the mean of those 2 values.The median is the data value separating the upper half of a data set from the lower half.16, 16, 16, 19, 20, 22, 23, 24, 24
16, 16, 16, 19, 20, 22, 23, 24, 24

The sum of twice a number and 5 is 21. What is the number?
Hello.
First, "twice a number" means we multiply 2 times that number.
Let the number be s.
Now, the sum of 2 times s and 5 is 21.
The product of 2 and s can be written like so:
[tex]\sf{2s[/tex]
Now, the sum of 2s and 5 is 21:
[tex]\sf{2s+5=21[/tex]
Subtract 5 from both sides:
[tex]\sf{2s=21-5[/tex]
[tex]\sf{2s=16}[/tex]
Now, divide both sides by 2:
[tex]\Large\boxed{\sf{s=8}}[/tex]
I hope it helps.
Have a nice day.
[tex]\boxed{imperturbability}[/tex]
x = 8
Step-by-step explanation:
Let the required number be x.
According to the given question,
=> 2x + 5 = 21
=> 2x = 21 - 5
=> 2x = 16
=> x = 16/2
=> x = 8

Can the side lengths of 7, 10, and 9 form a triangle?
========================================================
Explanation:
Add the first two sides to get 7+10 = 17 which is larger than the third side (9)Add the first and last sides to get 7+9 = 16 which is larger than the second side (10)Add the last two sides to get 10+9 = 19 which is larger than the first side (7)As that list above shows, adding any two sides results in a sum larger than the third remaining side. The conditions of the triangle inequality theorem have been met to allow for a triangle to be formed.
In general the triangle inequality theorem is:
a+b > ca+c > bb+c > aThe order doesn't matter. All that's important is that all three conditions are met.

A cylinder has a height of 20 centimeters and a radius of 11 centimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
7598.8 [tex]cm^{2}[/tex]
Step-by-step explanation:
v (volume) = π[tex]r^{2}[/tex]h
v = 3.14 x [tex]11^{2}[/tex] x 20
v = 3.14 x 121 x 20
v = 7598.8
Answer:
7598.8 cm³
Step-by-step explanation:
Given :-
height = 20 cm
radius = 11 cm
value of π = 3.14
Formula to be used :-
Volume of cylinder = πr²h
Inputting the values :-
V = 3.14 x 11 x 11 x 20
= 3.14 x 121 x 20
= 3.14 x 2420
= 7598.8 cm³

Sarah wants to swim across a 193 m river. Due to the current she is swept 67 m downriver from where she wanted to be. What is the length that she actually swam from start to where she ended? Round to the nearest tenth
Answer:
Step-by-step explanation:
Sarah swam the diagonal length of a right-angled triangle with sides of river width, 193m and how far she was swept downstream, 67m.
By Pythagorean Theorem, distance swam = sqrt(193^2+67^2)
= 204.3 m

Two car rental companies have the following payment plans: Cart: $90 per week and 15c per kilometre Renta: $110 per week and 10c per kilometre What is the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta?
Using linear function concepts, it is found that the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.For each car, Cart and Renta, the linear functions are given by:
C(k) = 90 + 0.15k
R(k) = 110 + 0.1k
Cart will cost less than Renta if:
C(k) < R(k)
Hence:
90 + 0.15k < 110 + 0.5k
0.05k < 20
k < 400
Hence, the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

Answer:
(i) gradient: 2/3
(ii) equation: y -1 = 2/3(x +1)
(iii) area: 10 square units
(iv) length: 4.12 units
Step-by-step explanation:
The gradient of a line is found by using the slope formula with two points on the line. The length between points is found using the distance formula, which is based on the Pythagorean theorem. The equation of a line can be written in several forms. One is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
__
(i)The points A and B can be used in the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (5 -1)/(5 -(-1)) = 4/6 = 2/3
The gradient of the line is 2/3.
__
(ii)Using the found slope in the point-slope equation with point A, we find the equation of the line to be ...
y -1 = 2/3(x +1)
__
(iii)The area of a triangle is found from the formula ...
A = 1/2bh . . . . . triangle with base b and height h
The base length will be the difference in x-coordinates of the horizontal segment AC: 4 -(-1) = 5.
The height will be the difference in y-coordinates from that horizontal segment and point B: 5 -1 = 4
Then the area of ABC is ...
A = 1/2(5)(4) = 10 . . . . square units
The area of ΔABC is 10 square units.
__
(iv)The length of BC is found from the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -4)² +(5 -1)²) = √(1 +16) = √17
d ≈ 4.12 . . . . units
The length of BC is about 4.12 units.

600x + 200y = 500x solve for x
yes thats all i need.
Answer:
x = -2y
Step-by-step explanation:
Simplifying
600x + 200y = 500x
Solving
600x + 200y = 500x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-500x' to each side of the equation.
600x + -500x + 200y = 500x + -500x
Combine like terms: 600x + -500x = 100x
100x + 200y = 500x + -500x
Combine like terms: 500x + -500x = 0
100x + 200y = 0
Add '-200y' to each side of the equation.
100x + 200y + -200y = 0 + -200y
Combine like terms: 200y + -200y = 0
100x + 0 = 0 + -200y
100x = 0 + -200y
Remove the zero:
100x = -200y
Divide each side by '100'.
x = -2y
Simplifying
x = -2y

Answer:
x= 0 and y=1
Step-by-step explanation:
1st multiply the first equation by 3
3 (3x-2y=2)
9x-6y=6
multiply the next equation by 2
2 (5x-3y=3)
10x-6y=6
subtract equation 1 from 2
(10x-6y)-(9x-6y)=6-6
10x-9x-6y+6y=0
x=0
put X in equation 1
3 (0)-2y=2
-2y=2
y=-1
so X and y are 0 and -1 respectively
For the following system a) What is the value of x? b ) What is the value of y ?
Answer:
x = 12
y = -23
Step-by-step explanation:
to solve for this i think we have to do:
y = -3x + 13
-
y = -2x + 1
-----------------------
0 = -x + 12
-x = -12
x = 12
then i think.... i think you have to substitute to one of the equations
y = -3(12) + 13
y = -36 + 13
y = -23
then to check we substitute to the second equation
-23 = -2(12) + 1 ?
-23 = -24 + 1?
-23 = -23
