Step-by-step explanation:
A farmer needs to enclose three sides of a meadow with a fence (the fourth side is a river). The farmer has 30 feet of fence and wants the meadow to have an area of 112 sq-feet. What should the dimensions of the meadow be? (For the purpose of this problem, the width will be the smaller dimension (needing two sides); the length with be the longer dimension (needing one side). Additionally, the length should be as long as possible.)
Answer:
Width = 7 feets ; length = 16 feets
Step-by-step explanation:
Given the following :
Area of meadow = 112 sq feet
Width = W (smaller dimension and 2 sides)
Length = L (longer dimension and 1 side)
Yards of fence = 30 feets ;
Hence,
L + W = 30
L + 2W = 30
L = 30 - 2W - - - (1)
Recall:
Area = L * W = 112
Substitute value of L
112 = (30 - 2W) * W
112 = 30W - 2W²
2W² - 30W + 112 = 0
W² - 15W + 56 = 0
W² - 8W - 7W + 56 = 0
W(W - 8) - 7(W - 8) = 0
(W - 8) = 0 or (W - 7) =0
W = 8 or W = 7
Since length should be as long as possible, we take the shorter width :
W = 7
L + 2W = 30
L = 30 - 14
L = 16 feets

Explain how to find the 52nd term using the explicit rule f(n)= 15n+10, then solve.
Answer:
790Step-by-step explanation:
Given the explicit rule function F(n) = 15n +10, in order to get the 52nd term of the sequence, we will have to substitute n = 52 into the rule given as shown;
f(52) = 15(52) + 10
f(52) = 780+10
f(52) = 790
Hence the 52nd term of the explicit rule is 790

At Rocking Horse Ranch, admission is $45 and trail rides are $22.50 per hour. At Saddlecreek Ranch, admission is
$30 and trail rides are $35 per hour. Solve your system from the previous question. Interpret the meaning of the solution in
the context of the problem.

Answer:
Step-by-step explanation:
R.H.R. y = 22.50x + 45
S. R. : y = 35x + 30
35x + 30 = 22.50x + 45
12.50x + 30 = 45
12.5x = 15
x = 2.5 hours it have an same price total
The equation represents the cost after x hours.
At Rocking Horse Ranch:
y = 45 + 22.50x
At Saddlecreek Ranch:
y = 30 + 35x
The cost for both the Rocking Horse Ranch and Saddlecreek Ranch is the same after 1.2 hours.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
We have,
At Rocking Horse Ranch:
Admission = $45
Trail rides per hour = $22.50
At Saddlecreek Ranch:
Admission = $30.
Trail rides per hour = $35
We have to find out after how many hours the cost from both the Ranch is the same.
We can make two equations as,
y = 45 + 22.50x ____(1)
y = 30 + 35x _____(2)
Now,
From (1) and (2) we get,
45 + 22.50x = 30 + 35x
45 - 30 = 35x - 22.50x
15 = 12.50x
x = 15/12.50
x = 1.2
Thus,
The cost for both the Rocking Horse Ranch and Saddlecreek Ranch is the same after 1.2 hours.

There are 48 people in a gym class what fraction represents the number of people running? 5/8 of the people were in spin class 1/3 of the people were lifting weights the remaining people were running
Answer: B.1/24
Step-by-step explanation:
Find out the number of people in spin class and those lifting weights, subtract them from the total number in the gym and then make this a fraction.
Step 1
Number of people in spin class ;
= 5/8 * 48
= 30 people
Number of people lifting weights;
= 1/3 * 48
= 16 people
Step 2
Number of people running
= 48 - 30 - 16
= 2 people
Step 3
Convert this to a fraction in its lowest form;
= 2/48
= 1/24

27x^6-152x^3+125=0
HELP ME AND PLEASE EXPLAIN!
Answer:
[tex]x=5/3\text{ or } x=1[/tex]
Step-by-step explanation:
We have the equation:
[tex]27x^6-152x^3+125=0[/tex]
We can solve this using u-substitution. Let's let u=x³. Therefore:
[tex]27(x^3)^2-152(x^3)+125=0[/tex]
Substitute all x³s for u:
[tex]27u^2-152u+125=0[/tex]
This is now in quadratic form. So, we can use the quadratic formula:
[tex]u=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Our a is 27, b is -152, and c is 125. So:
[tex]u=\frac{-(-152)\pm \sqrt{(-152)^2-4(27)(125)}}{2(27)}[/tex]
Simplify:
[tex]u=\frac{152\pm\sqrt{9604}}{54}[/tex]
Simplify:
[tex]u=\frac{152\pm 98}{54}[/tex]
Reduce. Divide everything by 2:
[tex]u=\frac{76\pm49}{27}[/tex]
Split into two cases:
[tex]u=\frac{76+49}{27}\text{ or } u=\frac{76-49}{27}[/tex]
Solve for each case:
[tex]u=\frac{125}{27}\text{ or } u=\frac{27}{27}=1[/tex]
Substitute back x³ for our u:
[tex]x^3=\frac{125}{27}\text{ or } x^3=1[/tex]
Take the cube root of each equation:
[tex]x=\sqrt[3]{\frac{125}{27}}\text{ or } x=\sqrt[3]1[/tex]
Evaluate:
[tex]x=5/3\text{ or } x=1[/tex]
And that's our two solutions.

The members of the drama club have 100 tickets to sell
to the school play. Students pay $5 per ticket, and
nonstudents pay $10 per ticket. The drama club needs
to collect at least $800 in total ticket sales. The system
of inequalities represents the number of student tickets,
s, and the number of nonstudent tickets, n, the members
must sell.
S + n < 100
5s + 10n > 800
Answer:40
Step-by-step explanation:
answer is 40
A
The number of tickets sold to the student is s = 40 (maximum) and to the nonstudent is n = 60(minimum) in order to collect at least $800 in total ticket sales.
The members of the drama club have 100 tickets to sell Students pay $5 per ticket, and nonstudents pay $10 per ticket. Inequalities given S + n < 100, 5s + 10n > 800. Maximum tickets for students and minimum tickets for nonstudents are to be determined.
Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let S + n = 100 -----(1)
5s + 10n = 800 ----(2)
Solving equations 1 and 2
S = 40 and n = 60
in order to hold the inequality s should be a maximum of 40 or n should be a minimum of 60.
Thus, the number of tickets sold to the student is s = 40 (maximum) and to the nonstudent is n = 60(minimum) in order to collect at least $800 in total ticket sales.

John could not decide, but he had 9 dollars he could spend on fruit kabobs that cast 1.75 dollars and smoothies that cost 2.50 dollars. He knew he wanted at least one each. What are some combinations he could afford? Show at least three possibilities.
Answer:
One fruit kabob and one smoothie
Two fruits kabobs and two smoothies
Three fruit kabobs and one smoothie
One fruit kabob and two smoothies
Explanation:
In this situation, the basic combination John can afford is simply to buy one fruit kabob and one smoothie ( $1.75 + $ 2.50 = $4.25) because he wants at least one unit of each item. Additionally, it is possible to add more units of each item to create new combinations or possibles, just make sure they do not total more than 9 dollars, which is the money John has. Here are some of the possible combinations:
Two fruit kabobs and two smoothies
Fruit kabobs: $1.75 x 2 = $3.5
Smoothies: $ 2.50 x 2 = $5
Total: $8.5
Three fruit kabobs and one smoothie
Fruit kabobs: $1.75 x 3 = $5.25
Smoothie: $2.50
Total: $7.75
One fruit kabob and two smoothies
Fruit kabob: $1.75
Smoothies: $2.50 x 2 = $5

Answer:
1 + i[tex]\sqrt{5}[/tex], 1 - i[tex]\sqrt{5}[/tex]
Step-by-step explanation:
A quadratic function is f(x) = a[tex]x^{2}[/tex] + bx + c
Your function with the given values is f(x) = 2[tex]x^{2}[/tex] - 4x + 12
To solve a quadratic function, you can use the quadratic formula
(-b +/- [tex]\sqrt{b^{2} - 4ac}[/tex]) / 2a
Fill in with your given values.
(4 +/- [tex]\sqrt{(-4^{2} - 4 (2) (12)}[/tex] ) / 2(2)
Simplify
(4 +/- [tex]\sqrt{16 - 96}[/tex]) / 4
(4 +/- [tex]\sqrt{-80}[/tex] ) / 4
Because there is a negative number under the square root making it an imaginary number put an i by it.
(4 +/- i[tex]\sqrt{80}[/tex]) / 4
80 is divisible by 16, a perfect square. 80 / 16 = 5
(4 +/- 4i[tex]\sqrt{5}[/tex]) / 4
Divide by 4
1 +/- i[tex]\sqrt{5}[/tex]
Your teacher may want you to list your radical without the i and just as [tex]\sqrt{-5}[/tex], so keep that in mind.
Don't forget to list it both as addition and subtraction.
