a right triangle with integer sides has area equal to 30. What is the length of its hypotenuse.
Answers
We have been given that a right triangle with integer sides has area equal to 30. We are asked to find the length of hypotenuse of right triangle.
We know that area of triangle is half the product of its base length and height.
Since our given triangle is a right triangle, so its base and height will be legs of right triangle.
[tex]\frac{1}{2}\cdot\text{Base}\times \text{Height}=\text{Area}[/tex]
[tex]\frac{1}{2}\cdot\text{Base}\times \text{Height}=30[/tex]
[tex]\frac{1}{2}\cdot 2\cdot\text{Base}\times \text{Height}=30\cdot 2[/tex]
[tex]\text{Base}\times \text{Height}=60[/tex]
This means that product of two bases is 60.
Now we need to find two multiples of 60 such that they are make a right triangle.
Multiples of 60:
1, 60
2, 30
3, 20
4, 15
5, 12
6, 10
We know that (5, 12 and 13) is a Pythagoras triplet.
[tex]5^2+12^2=13^2[/tex]
[tex]25+144=169[/tex]
[tex]169=169[/tex]
Therefore, the hypotenuse of right triangle is 13 units.

A movie theater charges $5 for an adult ticket and $2 for a child's ticket. One Saturday, the theater sold 785 tickets for $3280. How many child's tickets and adult's tickets were sold that Saturday?
Answers
Answer:
5x + 2y = 3280
x+y = 785
x = 785 - y
5*(785 - y) + 2y = 3280
3925 - 5y + 2y = 3280
3925 - 3280 - 3y = 0
645 = 3y
y=645/3=215
x=785-215 = 570
Adults - 570 tickets, childs - 215 tickets.
570*5 + 215*2 = 3280

Find an ordered pair , x y that is a solution to the equation. 3x-y=1
Answers
Answer:
2,5
Step-by-step explanation:
2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.
To find the solution to the equation 3x - y = 1, we can choose a value for x and solve for y. By substituting x = 2, we find that the ordered pair (x, y) = (2, 5) is a solution.
Explanation:To find an ordered pair (x, y) that is a solution to the equation 3x - y = 1, we first need to choose a value for x and then solve for y. Let's choose x = 2:
Substitute x = 2 into the equation: 3(2) - y = 1Simplify: 6 - y = 1Isolate y by subtracting 6 from both sides: -y = 1 - 6Simplify: -y = -5Divide by -1 to solve for y: y = 5
Therefore, the ordered pair (x, y) = (2, 5) is a solution to the equation 3x - y = 1.

Answers
2.06 is equivalent to 2.060
The numbers 2.06 and 2.060 are equal. So, the correct symbol to represent their relationship is C. = (equal) Therefore, the correct answer is option c.
The numbers 2.06 and 2.060 have the same numerical value; they represent the same quantity. The difference between them is the way they are expressed in terms of decimal places.
2.06: This number has two decimal places.
2.060: This number has three decimal places.
However, since there are no digits beyond the third decimal place in either number, the extra zero in 2.060 doesn't change the value of the number. In other words, the two numbers are numerically identical.
Therefore, you can represent their relationship with the "equals" symbol ( = ), indicating that they are equal:
C. = (equal)

find the area of the triangle whose vertices are x(3,2) y(-1,0)and z(1,-12)
Answers
Answer:
The triangle whose vertices are x(3,2) y(-1,0)and z(1,-12).
=> xy = sqrt(4^2 + 2^2) = 4.472
=> xz = sqrt(2^2 + 14^2) = 14.142
=> yz = sqrt(2^2 + 12^2) = 12.166
=> Perimeter/2 = P = (xy + yz + xz)/2 = (4.472 + 14.142 + 12.166)/2 = 15.39
=> Applying Heron's formula, the area of triangle would be:
A = sqrt(P*(P-xy)*(P-xz)*(P-yz))
= sqrt(15.39*(15.39 - 4.472)*(15.39 - 14.142 )*(15.39 - 12.166))
= 26.001
= ~26

Matt and Taylor are taking a test. The test is designed to produce an overall mean score of 80, with a standard deviation of 6 for all test takers. Suppose Matt scored an 85 on the test and Taylor scored a 78 on the test. Given that the data is approximately normal, find the probability that another test taker, chosen at random, scored less than Matt and more than Taylor.
Answers
Answer:
P (r) = 1/3
Step-by-step explanation:
Matt 85 - 80 = +(5)
Taylor 80-78 = - (2)
+5-2 = 3 rise so deviation is the same.
Another test taker in 4 outcomes less than taylor more than taylor less than matt more than matt, would also be the same as AnB union.
So their are 3 outcomes = 1/3 = 0.333 rep.

How many 5-letter “words” can be formed from the letters of the word FORMULATED, if each will have the vowels at the two ends on the “word”?
Answers
Final answer:
To calculate the number of 5-letter "words" with vowels on the ends from 'FORMULATED', you multiply the number of ways to choose the two vowels (4 x 3) by the number of ways to choose the three different consonants (6P3; 6 x 5 x 4), resulting in 1440 different possible "words."
Explanation:
To determine the number of 5-letter "words" that can be formed from the letters of the word FORMULATED with vowels at both ends, we need to consider two parts: the selection of vowels and the selection of consonants. The word FORMULATED contains four vowels (O, U, A, E) and six consonants (F, R, M, L, T, D).
First, we choose the vowels for the ends. There are 4 vowels, which means we can select the first vowel in 4 ways. After selecting the first vowel, we can still choose the second vowel from the remaining 3 vowels (since we are allowing repetitions). This gives us 4 x 3 possibilities for the vowels.
Now we select the consonants for the center three positions. We have 6 different consonants to choose from, and since each position must be filled with a unique letter, we can select these in 6P3 (6 permute 3) ways, which is calculated as 6 x 5 x 4.
Finally, to find the total number of 5-letter "words," we multiply the number of ways to choose the vowels by the number of ways to choose the consonants, giving us 4 x 3 x 6 x 5 x 4 which equals 1440 possible "words."
If Logan's family can drive 23 1/8 miles on 1 gallon of gas, how far can they drive on 17 gallons?
Answers
Answer:
393 1/8 miles
Step-by-step explanation:
Distance driven in 1 gallon of gas = 23 1/8 miles
23 1/8 miles is mixed fraction.
converting 23 1/8 into improper fraction
23 1/8 = (23*8 + 1)/8 = 185/8
Thus 1 gallon of gas can drive 185/8 miles. ____________1
Since distance for 17 gallons is needed.
we multiply both gallon of gas and distance with 17.
1 *17 gallon of gas can drive 185/8*17 miles
17 gallon of gas can drive (185/8)*17 miles
=>17 gallon of gas can drive (3,145)/8 miles
converting (3,145)/8 miles into mixed fraction we have 393 1/8 .
Thus, Logan's family can drive 393 1/8 miles on 17 gallons.
Which of the following represents the symmetric property of congruence?
Question 3 options:
A)
If ≅ , then ≅
B)
If ≅ , then ≅
C)
≅
D)
If ≅ and ≅ , then ≅
Answers
Answer:
The symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.
Step-by-step explanation:
Two triangles are said to be congruent if they have the same three sides and the same three angles, not necessarily the same sides or the same angles are equal.
The properties of congruence are:
Reflexive property:
For all angles A, ∠A ≅ ∠A. That is, all angles are congruent to themselves.
If AB is side of a triangle then, AB ≅ AB.
Symmetric Property:
For any angles A and B if, ∠A ≅ ∠B, then ∠B ≅ ∠A.
For sides AB and CB of a triangle if, AB ≅ CB, then CB ≅ AB.
Transitive property:
For any angles A, B and C if, ∠A ≅ ∠B, and ∠B ≅ ∠C then ∠A ≅ ∠C.
For sides AB, CB and CA of a triangle if, AB ≅ CB, and CB ≅ CA, then AB ≅ CA.
Thus, the symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.
Final answer:
The symmetric property of congruence is represented by Option B: If AB ≡ CD, then CD ≡ AB, aligning with the principle that if one quantity equals another, the second equals the first as well.
Explanation:
The symmetric property of congruence states that if one geometric figure is congruent to another, then the second is also congruent to the first. This is a reflection of the more general symmetric property of equality in algebra, which states that if one quantity equals another, the second equals the first as well.
Looking at the provided options, the one that represents the symmetric property of congruence is:
Option B: If AB ≡ CD, then CD ≡ AB.
This option correctly reflects the symmetric property, which can be written as if p ≡ q, then q ≡ p where p and q are geometric figures or algebraic expressions.
