Name the triangle with the following characteristics. sides: 5 cm, 6 cm, 7 cm; Angles: 75° and 60°.
The answer is: The triangle is a SCALENE Triangle.
As all the sides of the triangle are unequal. Therefore,it is a scalene triangle.
What are the 3 main types of triangles?
According to the length of sides, triangles can be classified into 3 categories i.e., Scalene, Isosceles, and Equilateral triangles.
A scalene triangle is a triangle in which all three sides are of different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.
An isosceles triangle is a triangle in which two sides have the same length.
An equilateral triangle is a triangle with all three sides of equal length, corresponding to what could also be known as a "regular" triangle.

Step-by-step explanation:
Ignatz repeatedly rolls a fair $6$-sided die. What is the probability that he rolls his first $5$ before he rolls his second (not necessarily distinct) even number?
The probability that Ignatz rolls his first 5 before he rolls his second (not necessarily distinct) even number is: 13/32
Events:Define Event A: Rolling 5 before an even number.
Define Event B: Rolling an even number before a 5 (complementary event to event A).
Sample Space: - The total number of outcomes for rolling a die 5 times is [tex]6^5[/tex] (each roll has 6 possibilities).Favorable Outcomes for Event A:- We can achieve event A in various scenarios where Ignatz rolls a 5 before encountering an even number. Let's consider each case:Case 1: 5 in the first roll (1 way). Then, any other number (not 2, 4, or 6) in the remaining rolls (5 possibilities each).
Favorable outcomes: [tex]1 * 5 * 5 * 5 * 5.[/tex]
Case 2: 5 in the second roll (similar to case 1).
Favorable outcomes: [tex]5 * 1 * 5 * 5 * 5.[/tex]
We can continue using the same logic for cases where 5 appears in the third, fourth, or fifth roll.
Total Favorable Outcomes for Event A:Since there are multiple ways to achieve event A, we add the favorable outcomes from each case.Total Favorable Outcomes (A) = Favorable Outcomes (Case 1) + Favorable Outcomes (Case 2) + ... + Favorable Outcomes (Case 5)
= [tex]1 * 5^4 + 5 * 1 * 5^4 + 5^2 * 1 * 5^3 + 5^3 * 1 * 5^2 + 5^4 * 1 * 5[/tex]
Probability of Event A:Probability (A) = Favorable Outcomes (A) / Total Outcomes
[tex]= ( 1 * 5^4 + 5 * 1 * 5^4 + 5^2 * 1 * 5^3 + 5^3 * 1 * 5^2 + 5^4 * 1 * 5) / 6^5[/tex]
Probability of Event B (complementary event):Event B is the opposite of event A. Since events A and B cover all possibilities, their probabilities sum to 1.
Probability (B) = 1 - Probability (A)
Therefore, the probability of rolling a 5 before an even number (event A) is 1 - Probability (B).

area of parallogram now = 8*10 = 80 square units
if the sides are multiplied by 4 the new dimensions would be
8*4 = 32, 10*4 = 40
area would be 32 *40 = 1280 square units
1280 /80 = 16
the area multiplied 16 times which is the multiple squared ( 4^2 = 16)
Write the equation in spherical coordinates. (a) 4z2 = 5x2 + 5y2 (b) x2 + 3z2 = 4
In spherical coordinates, equations in the form of [tex]4z^2 = 5x^2 + 5y^2[/tex] can be written as [tex]4ρ^2cos^2(θ) = 5ρ^2sin^2(θ)[/tex], and equations in the form of x^2 + 3z^2 = 4 can be written as ρ^2sin^2(θ) + 3ρ^2cos^2(θ) = 4.
Explanation:(a) In spherical coordinates, the equation [tex]4z2 = 5x2 + 5y2[/tex] can be written as [tex]4ρ2cos2(θ) = 5ρ2sin2(θ)[/tex]. Here, ρ represents the distance from the origin to the point and θ represents the angle measured from the positive x-axis to the point in the xy-plane.

how much apple juice does each person get if 6 people share 2 and 2/3 quarts equally
The fraction of apple juice shared by 6 people is A = 4/9 of the apple juice
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction of apple juice shared by 6 people be A
Let the total number of people be represented as n = 6 people
Now , the fraction of total amount of apple juice = 2 2/3
The fraction of total amount of apple juice T = ( 8/3 ) of apple juice
And , the equation is
A = fraction of total amount of apple juice T / total number of people n
On simplifying , we get
A = ( 8/3 ) / 6
A = ( 8/18 )
Divide by 2 on both numerator and denominator of the fraction , we get
A = 4/9 of the apple juice
Therefore , the value of A is 4/9
Hence , the fraction of apple juice is ( 4/9 ) equally

Why do some absolute value equations have no solution?
Last year Jeremy had $7900 in medical expenses. If his AGI was $89,000, will he be able to deduct his medical expenses and if so, what amount?
Answer:
He will be able to deduct his medical expenses by $1225.
Step-by-step explanation:
If his medical expenses are over 7.5% of his AGI he can reduce it to 7.5%.
His AGI was $89,000. How much is 7.5% of that?
0.075*89000 = $6675.
His expenses are over 7.5%, so yes, he can reduce.
He can reduce from $7900 to $6675, so 7900 - 6675 = $1225

Three friends all live on the same street that runs west to east. Ben lives 4 blocks from Ann. Carl lives 2 blocks from Ben. If the street is represented by a number line and Ann's house is located at 0, what are the possible locations for Carl's house?
Answer:
The possible locations are,
2, -2, 6 or -6
Step-by-step explanation:
Given,
The location of Ann's house in the number line = 0,
∵ Ben lives 4 blocks from Ann.
So, the possible location of Ben's house = 4 ( right of ann's house ) or - 4 ( left of ann's house )
Now, Carl lives 2 blocks from Ben,
So, the possible location of Carl's house
Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )
Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )
The possible locations of Carl's house are - 6, 6, 2 or - 2
Let :
Ben's location = B
Carl's position = C
Ann's position = A
Using the Number line illustration :
Ann's position = 0
Ben's possible positions :
4 blocks(units) from Ann = ± 4Carl's location :

It takes one machine 25 minutes to pick a bale of cotton and another machine 30 minutes to compete the same job. If both machines are used, how long will it take them to pick a bale of cotton?
Answer:
13.64 minutes
Step-by-step explanation:
The first machine works at the rate x = 1 bale/ 25 min.
The second machine works at the rate y = 1 bale/30 min.
The combined rate is
x + y = 1/25 + 1/30 bales/min
= (30 + 25)/(25*30) = 55/750
= 11/150 bales/min
The time for both machines to pick 1 bale of cotton is
(1 bale)/(11/150 bales/min) = 150/11 min = 13.64 min
So if you take rsm, you have to input 13.64 otherwise it won't work. :)
