Mrs. Worthington purchased single slices of pizza for 24 students. The cost for 24 slices of pizza is $25.65. What is the cost for one slice of pizza? ______
Complete the chart.
Answers
Answer:
Step-by-step explanation:
I am not sure how much to answer. I'll confine myself to the written question.
Equation
24 students 1 0iece of pizza each = 25.65
1 piece of pizza = x
Set up a proportion
24 students are given 24 pieces of pizza -- Cost 25.65
1 student 1 piece of pizza = x
Solution
24 / 1 = 25.65/x Cross Multiply
24x = 1 * 25.65 Divide both sides by 24
24x/24 = 25.65/24
x = 1.07 / slice.

Answer:
∠2 = 41°
Step-by-step explanation:
This is because, all three interior angles in a triangle will have a sum of 180 degrees.
So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;
49 + 90 + x = 180
139 + x = 180
-139 -139
x = 41°, ∠2 = 41°
Which value for x will result in the greatest relative frequency given discrete random variable X, when X∼B(4,110)? x=5 x=1 x=0 x=3
Answers
The greatest relative frequency is the relative frequency that gives the highest probability
The greatest relative frequency given discrete random variable X, when X∼B(4,110) is x=3
How to determine the greatest relative frequencyFor a discrete random variable, the smaller the value of the variable, the higher its relative frequency.
This means that:
A variable x = 0 would have a greater relative frequency than a variable x = n, where n > 0

A 15 ft long cable is connected from a hook to the top of a pole that has an unknown height. The distance from the hook to the base of the pole is 3 ft shorter than the height of the pole.
a. What can you use to find the height of the pole?
b. Write and solve a quadratic equation to find the height of the pole.
c. How far is the hook from the base of the pole?
Answers
Answer:
a) Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
b) Given:
a = (x - 3)b = xc = 15Substituting these values into the equation and rearranging:
⇒ (x - 3)² + x² = 15²
⇒ x² - 6x + 9 + x² = 225
⇒ 2x² - 6x - 216 = 0
c) Solve 2x² - 6x - 216 = 0 by factorizing:
2x² - 6x - 216 = 0
⇒ x² - 3x - 108 = 0
⇒ x² - 12x + 9x - 108 = 0
⇒ x(x - 12) + 9(x - 12) = 0
⇒ (x - 12)(x + 9) = 0
⇒ x - 12 = 0 ⇒ x = 12
⇒ x + 9 = 0 ⇒ x = -9
As distance is positive, x = 12 only.
Therefore, the height of the pole is 12 ft.
So the distance from the hook to the base = 12 - 3 = 9 ft
We need x
Apply Pythagorean theorem
[tex]\\ \rm\Rrightarrow 15^2-x^2=(x-3)^2[/tex]
[tex]\\ \rm\Rrightarrow 225-x^2=x^2-6x+9[/tex]
[tex]\\ \rm\Rrightarrow 2x^2-6x-216=0[/tex]

The number of dogs that are not puppies is 17, the number of adult dogs without long hair is 6, the number of puppy dogs with long hair is 8 and the number of puppy dogs without long hair is 7.
What is the information missing?To complete the chart it is necessary to determine:
Number of dogs that are not puppies.Number of puppies with and without long hairNumber of adult dogs without long hairNumber of dogs that are not puppies:
32 (total dogs) - 15 (puppies) = 17 dogsAdult dogs without long hair:
17 (total adult dogs) - 11 (adult dogs with long hair) = 6 dogsPuppy dogs with and without long hair
Total of puppy dogs = 15, this number can be obtained by adding 9+6 or 7+8. From these combinations, the only one that meets the rule "There are 6 more dogs that have long hair than dogs that do not have long hair" is 8 puppies with long hair and 7 puppies without long hair.

Problem 5
Answer: 300 square inches------------------
Work Shown:
a = 15
b = unknown
c = 25
a^2 + b^2 = c^2
15^2 + b^2 = 25^2
225 + b^2 = 625
b^2 = 625 - 225
b^2 = 400
b = sqrt(400)
b = 20
The rectangle is a = 15 by b = 20 to get an area of ab = 15*20 = 300 square inches.
=======================================================
Problem 6
Answer:
Part A) The area = 48 square inchesPart B) The area = 16*sqrt(2) square inches------------------
Work Shown:
Part A)
area = base*height/2
area = 8*12/2
area = 96/2
area = 48
Part B)
a^2 + b^2 = c^2
8^2 + b^2 = 12^2
64 + b^2 = 144
b^2 = 144 - 64
b^2 = 80
b = sqrt(80)
b = sqrt(16*5)
b = sqrt(16)*sqrt(5)
b = 4*sqrt(5)
Therefore,
area = base*height/2
area = a*b/2
area = 8*4*sqrt(5)/2
area = 16*sqrt(2)
=======================================================
Problem 7
Answer: 36 cm------------------
Work Shown:
area = 81
area = x^2
x^2 = 81
x = sqrt(81)
x = 9
The side lengths of the square are 9 cm each.
P = perimeter
P = 4x
P = 4*9
P = 36
=======================================================
Problem 8
Answer: 12.5*sqrt(15)------------------
Work Shown:
The horizontal base of 10 is cut in half to get 5.
a = 5 = horizontal side
b = unknown height
c = 20 = hypotenuse
a^2 + b^2 = c^2
5^2 + b^2 = 20^2
25 + b^2 = 400
b^2 = 400 - 25
b^2 = 375
b = sqrt(375)
b = sqrt(25*15)
b = sqrt(25)*sqrt(15)
b = 5*sqrt(15)
area = base*height/2
area = a*b/2
area = 5*5*sqrt(15)/2
area = 12.5*sqrt(15)

Function f(x), h(x), k(x) and t(x) will have real roots while function g(x) and p(x) will have imaginary roots.
Given quadratic functions are:
[tex]1) f(x)= x^{2} +6x+8\\2)g(x) = x^{2} +4x+8\\3)h(x) = x^{2} -12x+32\\4)k(x)=x^{2} +4x-1\\5)p(x)=5x^{2} +5x+4\\6)t(x) = x^{2} -2x-15[/tex]
What is the general form of a quadratic equation?The general form of a quadratic equation is:
[tex]ax^{2} +bx+c=0[/tex]
On comparing [tex]x^{2} +6x+8 =0[/tex] with the general form,
a=1, b=6, c=8
If discriminant D=b²-4ac is greater than zero, the quadratic equation will have two distinct real roots, if D is less than zero, roots will be imaginary.
So, discriminant D for f(x)=0 will be:
[tex]b^{2} -4ac[/tex] = [tex]6^{2} -4*1*8 = 4[/tex] i.e. greater than zero.
So, the quadratic function [tex]f(x) = x^{2} +6x+8[/tex] will have two real distinct
roots.
Similarly, h(x), k(x), and t(x) will have real roots since their discriminants are greater than zero.
Thus, Function f(x), h(x), k(x) and t(x) will have real roots while function g(x) and p(x) will have imaginary roots.
