a square and a triangle have equal perimeters. the square has a perimeter of 4(2p-4), and the triangle has a perimeter of 4p+36. find the perimeter value.
A. p= 72
B. p= 44
C. p= 88
D. p= 36
Answer:
C
Step-by-step explanation:
Since the figures have equal perimeters we can equate them, thus
4(2p - 4) = 4p + 36 ← distribute left side
8p - 16 = 4p + 36 ( subtract 4p from both sides )
4p - 16 = 36 ( add 16 to both sides )
4p = 52 ( divide both sides by 4 )
p = 13
Substitute p = 13 into either of the 2 expressions, then
4p + 36 = 4(13) + 36 = 52 + 38 = 88 → C
The value of perimeter is found as 88 units. The correct option is (C).
How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
As per the question the perimeters are equal.
The following equation can be written as,
4(2p - 4) = 4p + 36
⇒ 8p - 16 = 4p + 36
⇒ 4p = 52
⇒ p = 13
Thus, the perimeter value can be obtained by substituting p = 13 in 4p + 36 as below,
⇒ 4 × 13 + 36 = 88
Hence, the perimeter value is 88 units.

A perimeter increased by four is twenty eight.
(As an equation)
Answer:
P+4=28, meaning that the original perimeter was 24
Step-by-step explanation:
Let's call the perimeter P.
Converting the words into an equation, you get:
P+4=28
Now, you can subtract 4 from both sides:
P+4-4=28-4
P=24

Solve the following system.

v=()x2 + 2*
2 + 2x-1 and 3x-y=1
Answer:
x = 1 + i, x = 1 - i
Step-by-step explanation:
Make the second equation y = 3x - 1
Substitute: 3x - 1 = 1/2x^2 + 2x
Simplify: 6x - 2 = x^2 + 4x
x^2 + 4x + 2 = 6x
x^2 - 2x + 2 = 0
Complete the square: x^2 - 2x + 1 = - 1
(x - 1)^2 = -1
x - 1 = ± √-1
Take out the negative: x - 1 = ± i
x = 1 + i, x = 1 - i
i is for imaginary number

A set of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars.
A leather sofa has a price of 2410 dollars.
What proportion of sofa prices are higher than the price of the leather sofa?
You may round your answer to four decimal places.
We have been given that a of sofa prices are normally distributed with a mean of 2500 dollars and a standard deviation of 200 dollars. A leather sofa has a price of 2410 dollars. We are asked to find the proportion of sofa prices that are higher than the price of the leather sofa.
First of all, we will find the z-score corresponding to sample score 2410.
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{2410-2500}{200}[/tex]
[tex]z=\frac{-90}{200}[/tex]
[tex]z=-0.45[/tex]
Now we need to find area under normal curve that is greater than z-score of [tex]-0.45[/tex] that is [tex]P(z>-0.45)[/tex].
Using formula [tex]P(z>a)=1-P(z<a)[/tex], we will get:
[tex]P(z>-0.45)=1-P(z<-0.45)[/tex]
Now we will find area under curve using normal distribution table.
[tex]P(z>-0.45)=1-0.32636[/tex]
[tex]P(z>-0.45)=0.67364[/tex]
Upon rounding to 4 decimal places, we will get:
[tex]P(z>-0.45)\approx 0.6736[/tex]
Therefore, approximately 0.6736 of sofa prices are higher than the price of the leather sofa.
Answer:
0.6736

A circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 3 m wide. Find
the area of the sidewalk in square meters. Use 3.14 for 1.
The area of the sidewalk is m?.
(Round to the nearest whole number as needed.)
Answer:
424
Step-by-step explanation:
pie r squared is area of a circle
21(squared)x3.14=1385
minus this from 24squaredx3.14 =1809
1385-1809=424
The area of the sidewalk is 226.08 m²
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The space enclosed by the boundary of a plane figure is called its area.
The area of a figure is the number of unit squares that cover the surface of a closed figure.
Area is measured in square units like cm² and m².
Given that, a circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 3 m wide. We need to find the area of the sidewalk.
To find the same, we will subtract the area of the inner circular region from the outer circular region,
The radius of the outer circular region = 21/2+3 = 10.5+3 = 13.5 m
The area of the sidewalk = πR²-πr², where R = radius of outer region and r = radius of inner region
= 3.14(13.5²-10.5²)
= 3.14 x 72
= 226.08 m²
Hence, the area of the sidewalk is 226.08 m²

The useful life of a radial tire is normally distributed with a mean of 30,000 miles and a standard deviation of 5000 miles. The company makes 10,000 tires a month. What is the probability that if a radial tire is purchased at random, it will last
between 20,000 and 35,000 miles?
Answer:
empirical rule: 81.5%
table or calculator: 81.9%
Step-by-step explanation:
The lower limit of the life range of interest has a z-score of ...
z = (x -μ)/σ = (20,000 -30,000)/5,000 = -2
The upper limit has a z-score of ...
z = (35,000 -30,000)/5,000 = 1
Empirical rule solution
The empirical rule tells you that 95% of the distribution lies within 2 standard deviations of the mean, so (100% -95%)/2 = 2.5% lie below z = -2. It also tells you 68% lie within 1 standard deviation of the mean, so (100% -68%)/2 = 16% lie above z = 1.
The fraction that lies within -2 to 1 standard deviations of the means is thus ...
(100% -2.5% -16%) = 81.5%
The probability the tire has a life in the desired range is about 81.5%.
__
Calculator solution
A probability calculator for the Normal distribution tells you that ...
P(-2 < z < 1) ≈ 0.8185946
The probability the tire has a life in the desired range is about 81.9%.

Answer:
14.14 ft
Step-by-step explanation:
In an isosceles triangle, the altitude and median is same. So the height divides the base AB equally such that AD = DB = 10, if the height is CD. So using Pythagoras theorem, we can find the hypotenuse AC in triangle ADC.
h² = b² + a²
AC² = AD² + CD²
AC² = 10² + 10²
AC² = 100 + 100
AC² = 200
AC = √200
AC ≈ 14.14 ft
