The given question is a quadratic equation and we can use several methods to get the solutions to this question. The solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4
Quadratic EquationQuadratic equation are polynomials with a second degree as it's highest power.
An example of a quadratic equation is
[tex]y = ax^2 + bx + c[/tex]
The given quadratic equation is [tex]24x^2 + 2x = 15[/tex]
Let's rearrange the equation
[tex]24x^2 + 2x = 15\\24x^2 + 2x - 15 = 0[/tex]
This implies that
a = 24b = 2 c = -15The equation or formula of quadratic formula is given as
[tex]y = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]
We can substitute the values into the equation and solve
[tex]y = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}\\y = \frac{-2 +- \sqrt{2^2 -4 * 24 * (-15)} }{2*24} \\y = \frac{-2+-\sqrt{4+1440} }{48} \\y = \frac{-2+-\sqrt{1444} }{48} \\y = \frac{-2+- 38}{48} \\y = \frac{-2+38}{48} \\y = \frac{3}{4}\\ \\or\\y = \frac{-2-38}{48} \\y = \frac{-40}{48} \\y = -\frac{5}{6}[/tex]
From the calculations above, the solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4

A+B+A+D=32
What does A+B=?
The value of A+B is 16
This question is related to division.To solve it, we will: divide the number after the equality, by the total number of variables (letters) that have.
A + B + A + D = 32
32 ÷ 4 = 8
< We know that the value of each variable is 8. So, to find the value of A + B, let's just add their respective values.
A + B
8 + 8 = 16
So, the value of A + B will be 16

What two operations would you use to solve the equation 3/4m - 6 = 12
-multiplication
-division
-addition
-subtraction
To solve this expression, we can use the mathematical operations: addition, multiplication and division. So the correct value, will be m = 1/24
This expression is an equation of the first fractional degree. To calculate, let's:
— move the negative - term to the other side of the positive equation, thus adding:
3/4m - 6 = 12
3/4m = 12 + 6
3/4m = 18
— Now, let's calculate without being fractional. We will isolate the variable multiply the terms with each other:
3/4m = 18
3 = 4m . 18
3 = 72m
— Finally, we'll turn this equation into a fraction, like this - simplifying the numerator and denominator by the same real number:
3 = 72m
m = 3/72
m = 3÷3 / 72÷3
m = 1/24
Therefore, the correct value of this expression is m = 1/24

Elsa played sports for 20 hours last week. How many more hours did she play baseball than volleyball?
Answers:
A:1
B:3
C:4
D:5
The number of more hours spent on baseball than volleyball is 3 hours. The correct option is B:3
Calculating time spent on sportFrom the question, we are to determine how many hours Elsa played baseball than volleyball
From the given information,
Elsa played sports for 20 hours
From the circle graph,
She spent 25% of the time on baseball
Time spent on baseball = 25% × 20 hours
Time spent on baseball = (25/100) × 20 hours
Time spent on baseball = 0.25 × 20 hours
Time spent on baseball = 5 hours
For time spent on volleyball
From the circle graph, she spent 10% of the total time on volleyball
Time spent on volleyball = 10% × 20 hours
Time spent on volleyball= (10/100) × 20 hours
Time spent on volleyball= 0.1 × 20 hours
Time spent on volleyball= 2 hours
The number of more hours spent on baseball than volleyball
= 5hours - 2 hours
The number of more hours spent on baseball than volleyball = 3 hours
Hence, the number of more hours spent on baseball than volleyball is 3 hours. The correct option is B:3

and find h (0)
Answer:
11, 29, 9
Step-by-step explanation:
substitute x = - 2, 4, 0 into h(x)
h(- 2) = (- 2)² + (- 2) + 9 = 4 - 2 + 9 = 2 + 9 = 11
h(4) = 4² + 4 + 9 = 16 + 4 + 9 = 29

Pam earns x dollars, Ryan earns (x+60) dollars and Rufus earns (x - 10) dollars. Together they earn a total of 530 dollars.
a) Calculate the value of x
b) the amount Ryan earns.
Answer:
A) 160 B) 220
Step-by-step explanation:
Combine like terms.
3x + 50 = 530.
Subtract 50 from both sides.
3x = 480.
Divide both sides by 3.
x = 160.
Since Ryan earns x + 60, add 60.
160 + 60 = 220.
Sally is packing for a holiday when she realizes that she only has enough room in her suitcase for two pairs of shoes. She randomly selects two pairs to pack from the 31 pairs of shoes that she owns in total.
If Sally has 6 pairs of high heels, what is the probability that she packs at least one pair of these?
Probability =__________
Using the hypergeometric distribution, it is found that there is a 0.3548 = 35.48% probability that she packs at least one pair of high heels.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.In this problem, we have that:
She has 31 pairs of shoes, hence N = 31.She has 6 pairs of high heels, hence k = 6.She selects two pairs, hence n = 2.The probability that she packs at least one pair of high heels is given by:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,31,2,6) = \frac{C_{6,0}C_{25,2}}{C_{31,2}} = 0.6452[/tex]
Then:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.6452 = 0.3548[/tex]
0.3548 = 35.48% probability that she packs at least one pair of high heels.

The straight-line distance between penny and Lisa is 70.1 feet if Lisa is laying on a towel at the beach, which is 50 feet from the base of the hotel.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
Let's suppose the distance between the Lisa and Penny is x feet.
We can draw a right-angle triangle for this situation.
As we can see in the right angle triangle.
tan54.5 = x/50 (from the right-angle triangle)
x = 50tan54.5
x = 70.09 ≈ 70.1 feet
Thus, the straight-line distance between penny and Lisa is 70.1 feet if Lisa is laying on a towel at the beach, which is 50 feet from the base of the hotel.
