What are sides of a pentagon with different sides ?
If the sides of a pentagon are not equal in measure, it is termed as an irregular pentagon. In this case, the perimeter of the pentagon can be calculated by using the basic formula, Perimeter = sum of its sides.
Given,
side 1 = 2x
side 2 = 10
side 3 = x+2
side 4 = 11
side 5 = 3x-2
Sum of all the sides of the pentagon,
2x+10+(x+2)+11+(3x-2)=63
2x+10+x+2+11+3x-2=63
6x+21=63
6x=63-21
6x=42
x=42/6
x=7

Write a compound inequality that represents the Fahrenheit temperatures between 50 degrees Celsius and 70 degrees Celsius.
Answers
Answer:
122 ≤ F ≤ 158
Step-by-step explanation:
First we convert the Celsius temperature to Fahrenheit
Mathematically, the formula to use is as follows;
F = 9/5C + 32
So 50 will be;
F = 9/5(50) + 32 = 90 + 32 = 122
70 will be
F = 9/5(70) + 32 = 126 + 32 = 158
So the inequality will be;
122 ≤ F ≤ 158

A plant is already 53 centimeters tall, and it will grow 1 cm every month.
Let H be the plants height (in centimeters) after M months.
Write an equation relating H to M. Then use this equation to find the plant height after 26 months.
Answers
Equation: h = 53 + 1m
Solving for m = 26: h = 79
The plant will be 79cm tall after 26 months
The height of the plant, H, is related to the number of months, M, by the equation H = M + 53. The plant will be 79 centimeters tall after 26 months.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The height of the plant, H, is related to the number of months, M, by the equation H = M + 53.
This equation represents the plant's initial height of 53 centimeters plus the additional height it will grow each month.
To find the plant's height after 26 months, we can substitute M = 26 into the equation:
H = M + 53
H = 26 + 53
H = 79 cm
So, the plant will be 79 centimeters tall after 26 months.

how many hundredths are in 11 wholes?
how many hundredths are in 3 tenths?
how many hundredths are in 11.3?
pls help!!!
Answers
Answer:
1) 11/100 or 0.11
2) 3/1000 or 0.003
3) 113/1000 0.113
Step-by-step explanation:
Firstly, hundredths is the same as 1/100.
Multiply every number by 1/100.
11/1 • 1/100 = 11/100 or 0.11
(Remember, 11 over 1 is the same as 1. Multiply the numerators and denominators and you get 11/100).
3/10 • 1/100 = 3/1000 or 0.003
11.3/1 • 1/100 = 113/1000 or 0.113
(Move the decimal once to the right to get rid of the decimal point).

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.
x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1
Answers
Answer:
The correct option is;
Arithmetic, common difference = -10
Step-by-step explanation:
The x terms given of the sequence are;
x [tex]{}[/tex] 1 2 3 4
f(x) [tex]{}[/tex] 5 -5 -15 -25
For a geometric progression, a·r/a = a·r²/ar = ar³/ar² = (n + 1)/n = r
We check to obtain -5/5 ≠ -15/(-5), therefore, the system is not a geometric progression
For ab arithmetic progression, we have;
(n + 1)th term - nth term = (n + 2)th term - (n + 1)th term = d (The common difference
We check to obtain -5 - 5 10, -15 - (-5) = -15 + 5 = -10 similarly, we have; -25 - (-15) = -25 + 15 = -10
Therefore, the sequence is an arithmetic sequence, with common difference = -10.

x = 3, y = 6,2 = 4
x = 6.) = 3,2 = 4
Answers
Answer:
x = 3, y = 6, z = 4
Step-by-step explanation:
If lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J, then JG = JH = JF = HI
Given
JG - 2x+ 2
JH - 2y-4
JF-8 a
HI - 3z-3,
Hence 2x+2 = 2y-4 = 3z-3 = 8
This means that
2x+2 = 8
2x = 8-2
2x = 6
x = 3
Also, 2y-4 = 8
2y = 8+4
2y = 12
y = 6
And 3z-3 = 8
3z = 8+3
3z = 11
z = 11/3
z = 3.67 ≈ 4
Hence x = 3, y = 6,z = 4
