Answer:
The lenghts of the sides are: 8 inches, 32 inches, 36 inches.
Step-by-step explanation:
Perimeter of a triangle:
The perimeter of a triangle is given by the sum of it's sides dimensions.
The ratio of the measures of the sides of a triangle is 2:8:9.
This means that their measures are:
The first measure is x
The second measure is of: [tex]\frac{8x}{2} = 4x[/tex]
The third measure is of [tex]\frac{9x}{2}[/tex]
So the perimeter will be of:
[tex]x + 4x + \frac{9x}{2} = 76[/tex]
[tex]5x + \frac{9x}{2} = 76[/tex]
[tex]\frac{10x}{2} + \frac{9x}{2} = 76[/tex]
[tex]\frac{19x}{2} = 76[/tex]
[tex]19x = 76*2[/tex]
Simplifying by 19
[tex]x = 4*2 = 8[/tex].
So, dimensions of:
[tex]8, 4*8 = 32, \frac{9*8}{2} = 36[/tex]
The lenghts of the sides are: 8 inches, 32 inches, 36 inches.

There are 23 animals in the barn. Some are chickens some are goats. There are 80 legs in all. How many of each animal is there?
There are 17 goats and 6 chickens
Explaining: (1) C + G = 23
As for legs:
(2) 2C + 4G = 80 (each C has 2 legs and each G has 4 legs)
Solving equation (1): C = 23 - G
Substituting in equation (2)
2(23 - G) + 4G = 80
2G = 34
G = 17
C = 6

Answer:
both x angles are equal to 40 degrees
Answer:
x would equal 40
Step-by-step explanation:
a line is 180, the angle inside the triangle is 100 and x is on both sides that means x would equal 40 because there is 2 x's and 100 is already a number and 180 is a line.
180 = x + x + 100
x + x + 100 - 100 = 180 - 100
x + x = 80
2x = 80
2 ÷ 2x = 80 ÷ 2
x = 40

Kimmie sells custom T-shirts for $12 each at the flea market every Saturday She usually sells 36 T-shirts Kimmie surveys her customers about whether they would buy her T-shirts at a different price. She determines that for every $1 increase in price she would sell two fewer T-shirts and for even $1 decrease in price, she would sell two more T-shirts, Which quadratic function can Kimmie use to model price increments vs. total income so that she can find the price at which her income is maximized?
Answer:
y = -2*x² + 60*x
Step-by-step explanation:
The general form of a quadratic function is:
y = a*x² + b*x + c
We need to determine a ; b ; and c. For that we have three conditions therefore
Condition 1 at x = 12 $ each T-shirts kimmie sells 36 units, then she gets
12* 36 = 432 $ or y = 432 and
432 = a(12)² + 12*b + c or 432 = 144*a + 12*b + c
Second condition selling at 13 $ each T-shirt she sells 34 , then
13*34 = 442
442 = a(13)² + 13*b + c or 442 = 169*a + 13*b + c
And the third condition
11*38 = 418
418 = a* ( 121) + 11*b + c 418 = 121*a + 11*b + c
We have a three equation system
432 = 144*a + 12*b + c (1)
442 = 169*a + 13*b + c (2)
418 = 121*a + 11*b + c (3)
We need to solve it for a, b and c
Subtracting (2) - (1) 10 = 25*a + b and subtracting (2) - (3)
24 = 48*a + 2*b
Then b = 10 - 25*a and 24 = 48*a + 2*( 10 - 25*a )
24 = 48*a + 20 - 50*a
24 - 20 = -2*a
4 = - 2*a
a = - 2 and b = 10 - 25*( -2) b = 60
Finally c is: 432 = 144*a + 12*b + c
432 = 144* ( -2) + 12*60 + c
432 = - 288 + 720 + c
432 = 432 + c
c = 0
The quadratic function is:
y = -2*x² + 60*x

whats the GCF for 1248
Answer:
None or 12 depending on what the question is. See explanation below.
Step-by-step explanation:
If the number is 1248:
A single number cannot have a GCF. The GCF has be for at least two numbers.
If the numbers are 12 and 48, then the GCF can be calculated.
Since 12 is a factor of 48, then the GCF of 12 and 48 is 12.
In general, to calculate the GCF do this:
To calculate it, find the prime factors of 12 and 48.
12 = 2^2 * 3
48 = 2^4 * 3
GCF is the product of common factors with lower exponent.
GCF = 2^2 * 3 = 12
what is the difference between 6 and 2 1/5.
Answer:
3.8
Step-by-step explanation:
6 - 2 1/5 = 6 - 11/5
= 6-2.2
=3.8
The difference between the 6 and 2 1/5 will be 3.8
What is a fraction?A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value). When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction. A proper fraction is also called fraction which is less than 1. A mixed fraction contains a sum of whole number and a proper fraction.
So, WE need to find the difference between the 6 and [tex]2 \frac{1}{5}[/tex].
First we need to convert the mixed fraction into simple fraction.
[tex]2 \frac{1}{5}[/tex] = 11/5
Therefore, the difference between them will be;
6 - [tex]2 \frac{1}{5}[/tex] = 6 - 11/5
= 6 - 2.2
= 3.8
Hence, the difference between the 6 and [tex]2 \frac{1}{5}[/tex] will be 3.8

A, B & C form the vertices of a triangle.
CAB = 90°, ABC = 60° and AB = 8.6.
Calculate the length of BC rounded to 3 SF.
BC =
Answer:
BC = 17.2.
Step-by-step explanation:
Since CAB = 90º, this is a right triangle.
The triangle format is given below:
C
A B
We have that AB = 8.6, and angle B measures 60º.
Length of BC:
BC is the hypotenyse.
Side AB is adjacent to angle B = 60º.
In a right triangle, angle [tex]\alpha[/tex], it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:
[tex]\cos{\alpha} = \frac{s}{h}[/tex]
In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So
[tex]\cos{\alpha} = \frac{s}{h}[/tex]
[tex]0.5 = \frac{8.6}{h}[/tex]
[tex]0.5h = 8.6[/tex]
[tex]h = \frac{8.6}{0.5}[/tex]
[tex]h = 17.2[/tex]
BC = 17.2.

want to study procrastination and social anxiety levels in undergraduate students at your university.You send a group email to all students to sign up to be contacted about participating in research.Only 2000 students signed up to be contacted about participating in the research. You choose asample of 100 students using a simple random sample from the students who signed up. You assigna number to every student in the research participant database from 1 to 2000 and use an SRSmethod to select 100 numbers.Is this sample biased
Answer:
Yes. There is a bias in the selected sample.
Step-by-step explanation:
Population of interest = undergraduate students at the university
Respondents to email requests = 2,000 students
Sample size = 100 students
Sample is based on the 2,000 respondents.
Therefore, sample is biased.
b) A sampling method is said to be biased if it systematically favors a group. By making some members of the student population systematically more likely to be selected in a sample than others, there is an occurrence of sampling bias. Usually, findings from biased samples can only be generalized to populations that share characteristics with the sample and to the entire population of interest.
Find the unit rate and determine which rate is greater: 500 miles in 10 hours or 125 miles in 2 hours.
Answer:
30 miles in 2.5 hours= 12 mph
Step-by-step explanation:
This is a fraction equal to
30 miles ÷ 2.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2.5
30 miles ÷ 2.5
2.5 hours ÷ 2.5
=
12 miles
1 hour

Let E denote the event that the roll of the die is evennumbered. (a) What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1
Answer:
What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1
=0,02
Step-by-step explanation:
Sample Space for rolling a die, S(1,2,3,4,5,6]
Since all the outcomes are equally P( rolling any numebre)=1/6
G1=(2,3,4,5,6)
Hence P(G1) =P (R2)+P (R3)+P (R4)+P (R5)+P (R6)
Hence P(G1) =5/6
and R3= [3]
Hence G1 ∩ R3 = [3] = R3
Hence P(G1 ∩ R3) =P( R3) =1/6
What is PR3 jG1 , the conditional probability that 3 is rolled given that the roll is greater than 1
P(G1 ∩ R3) / P(G1) = (1/6)/ (5/6=
