20.8,15,17
21.2,4,7
22.7,24,25
23.3,9,10
24.12,13,25
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.

What type of triangle is ABC?
Give reasons for your answer.
Answer:
I'll say that it is a scalene triangle because all of the sides of the triangle have different lengths.
Angle CAB is congruent to angle ACD because they are alternate interior angles (note the parallel lines AB and DE). So this makes angle CAB to be 50 degrees.
For similar reasoning, angle BCE = angle ABC = 80 degrees.
Focus on the angles that are centered at point C. Those three angles form a straight line so they add to 180 degrees.
(angle ACD) + (angle ACB) + (angle BCE) = 180
(50) + (angle ACB) + (80) = 180
(angle ACB) + 130 = 180
angle ACB = 180-130
angle ACB = 50 degrees
Ultimately, this leads to triangle ABC having the interior angles of A = 50, B = 80 and C = 50.
Because we have exactly two interior angles that are the same measure, this must mean triangle ABC is isosceles. The congruent angles are opposite the congruent sides, meaning that AB = BC.

There is a stack of 10 cards, each given a different number from 1 to 10. Suppose we select a card randomly from the stack, replace it, and then randomly
select another card. What is the probability that the first card is an even number and the second card is less than 3?
Write your answer as a fraction in simplest form.
Answer:
1/10.
Step-by-step explanation:
The probability of getting an even card out of 10 cards numbered 1 - 10 is 1/2. The even numbers available are 2, 4, 6, 8, and 10 while the odd ones available are 1, 3, 5, 7, and 9. So half the outcomes could come out even.
The probability the second card is less than two is 1/5 (2/10 simplified). Since there are 10 cards with numbers 1-10, only two cards will have numbers less than 3, 1 and 2.
To find the total probability, multiply the two. (1/2) * (1/5) = 1/10. There is a 1 out of 10 chance that the first card is even and the second card is less than 3.

Arianna solved a fraction division problem using the rule " multiply by the reciprocal ". Her work is shown below 2/3 divided by 4/5 2/3 x 4/5 = 8/15
Answer:
2/3 divided by 4/5 = 5/6
Step-by-step explanation:
Arianna working:
2/3 divided by 4/5
= 2/3 x 4/5
= 8/15
Correct working:
2/3 divided by 4/5
= 2/3 ÷ 4/5
Multiply 2/3 by the reciprocal of 4/5
= 2/3 × 5/4
= (2*5) / (3*4)
= 10/12
= 5/6
2/3 divided by 4/5 = 5/6
Arianna's mistake was she didn't multiply by the reciprocal of 4/5

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 10 men was 35 minutes per day. The standard deviation was 10 minutes per day. The mean listening time for a sample of 12 women was also 35 minutes, but the standard deviation of the sample was 12 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women
Answer:
No ;
Step-by-step explanation:
Given ;
s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12
Hypothesis :
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44
The Pvalue using the Pvalue from Ftest calculator :
Numerator df = 12 - 1 = 11
Denominator df = 10 - 1 = 9
Pvalue = 0.2969
At α = 0.1
If Pvalue > α ; Fail to reject H0
0.2969 > 0.1 ; Hence, we fail to reject the Null
Hence, we cannot conclude that variation exists

The divisor and quotient can be interchanged to find the divisor:
[tex]\dfrac{18n^6+27n^5-36n^4}{2n^2+3n-4}=\boxed{\text{Blank 1}}[/tex]
Such division is carried out by first finding the quotient of the highest-degree terms:

This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?
Answer:
El valor de cada cuota fija es de $500.
Step-by-step explanation:
Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:
8000-6500=1500
1500/3=500
De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.
A football field measures 300 feet in length. It can also be expressed as approximately
5.7 x 10^n .
If there are 5,280 feet in 1 mile , which is the most reasonable value of n.
Answer: n=-2
Step-by-step explanation:
Given
The length of the football field is [tex]300\ ft[/tex]
In the mile, it can be expressed as [tex]5.7\times 10^n\ mile[/tex]
Also, [tex]5280\ ft=1\ mile[/tex] or
[tex]1\ ft=\dfrac{1}{5280}\ miles\\\\1\ ft=1.893\times 10^{-4}\ miles[/tex]
converting [tex]300\ ft[/tex] to miles
[tex]\Rightarrow 300\times 1.893\times 10^{-4}\\\Rightarrow 5.68\times 10^{-2}\approx 5.7\times 10^{-2}[/tex]
Comparing it with the given value [tex]5.7\times 10^n\ mile[/tex]
we get [tex]n=-2[/tex]

 A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and a height of 60 centimeters. If the company used 54,259.2 cm3 of steel, how many rods did it make? Use 3.14 do not round your answer +Help me plz
Answer:
72 rods
Step-by-step explanation:
First, find the volume of each rod, using the formula V = [tex]\pi[/tex]r²h
Plug in pi, the radius, and height, and solve:
V = [tex]\pi[/tex]r²h
V = (3.14)(2²)(60)
V = (3.14)(4)(60)
V = 753.6
So, each rod has 753.6 cm³ of steel.
Divide 54,259.2 by this to find how many rods it will make:
54,259.2 / 753.6
= 72
So, it will make 72 rods.

the sum of two numbers is 30 the difference between three times the first number and twice the second is 60
Answer
Let the first no. be 2x
second no. =x
third no. =2x/3
A/Q
2x+x+2x/3=132
11x/3=132
x=36.
Hence the second no. is 36
let the first number be x
then second number=30-x
3x-2(30-x)=60
3x-60+2x=60
x=60+60
x=120
