Kate is making hamburgers for her friends and has pounds of hamburger. How many -pound hamburgers can she make?
Answers
Answer:
25 hamburgers
Step-by-step explanation:
Kate is making hamburgers for her friends and has 8 1/3 pounds of hamburger. How many 1/3-pound hamburgers can she make
Solution:
Given that Kate has 8 1/3 pounds of hamburger and she wants to make various hamburgers of 1/3 pound each. To determine the number of hamburgers she can make, we just have to divide the pounds of hamburger (8 1/3 pounds) by the 1/3 pounds.
8 1/3 pounds = [(8*3) + 1] / 3 = (24 + 1) / 3 = 25/3 pounds of hamburger
Therefore:
Number of hamburgers she can make = (25/3 pounds) / (1/3 pound) = 25 hamburgers

If f (n)= - 3n + 2, what is the value of f(12) ?
Answers
Answer:
Step-by-step explanation:
f(n)= -3n + 2
to find :f(12)
substitute 12 in place of n
f(12)= -3*12 + 2
f(12)=-36 + 2
f(12)= -34
The value of the f(12) is equal to -46 where the expression is
f(n) = -3n + 2.
What is an expression?Any mathematical statement which consist of numbers , variables and arithmetic operations is known as expression. An expression gives some numerical value when we put the value of variables in it.
Here, f(n)= -3n + 2 is the given expression.
So, we can find the value of f(12) by putting n=12 in f(n).
Put n=12 in f(n), we get
f(12)= (-3)×12 + 2
= -48 + 2
= -46
Hence, the value of f(12) is -46.

What is the area of a rectangle with side lengths 25 2 5 feet and 46 4 6 feet? Use the grid to help you.
Answers
Answer:
1185 10/30 square feet
Step-by-step explanation:
Area of a rectangle = length * width
Given
Length = 25 2/5 feet
width = 46 4/6
Substitute into the formula;
Area = 25 2/5 * 46 4/6
Area = 127/5 * 280/6
Area = 35,560/30
Area = 1185 10/30
Hence the area of the rectangle is 1185 10/30 square feet

f(x)=5x−3, find f(2)f(2)
Answers
Answer:
f(2)f(2) = 49
Step-by-step explanation:
Note that f(2)f(2) is the same as [f(2)]^2.
If f(x) = 5x - 3, then f(2) = 5(2) - 3, or f(2) = 7, and so:
f(2)f(2) = [f(2)]^2 = 7^2 = 49
Thus, f(2)f(2) = 49

The school that Willie goes to is selling tickets to the annual talent show. On the first day of
ticket sales the school sold 12 senior citizen tickets and 5 child tickets for a total of $102. The
school took in $156 on the second day by selling 14 senior citizen tickets and 12 child tickets.
Find the price of a senior citizen ticket.
A $6
B $7
C$10
D $4
Answers
Answer: A $6
Step-by-step explanation:
Let x = price per child ticket, y= price per senior ticket.
As per given, we have
5x+12y=102 (i)
12x+14y=156 (ii)
From (i), we have
[tex]x=\dfrac{102-12y}{5}[/tex] (iii)
Put value of x in (ii), we get
[tex]12(\dfrac{102-12y}{5})+14y=156\\\\\\ \dfrac{1224-74y}{5}=156\\\\\\1224-74y=5\times156\\\\\\ 1224-74y=780\\\\\\ 74y=1224-780\\\\\\ 74y=444\\\\ y=\dfrac{444}{74}\\\\\\ y=6[/tex]
Hence, the price of senior ticket = $6

Which of the following are magnitudes for rotational symmetry of the regular octagon below about the marked point?
Answers
The magnitude of rotational symmetry of the regular octagon below the marked point is 45°, so option A is correct.
What is octagon?Eight sides, eight internal angles, and eight vertices are the characteristics of an octagon. An octagon is referred to as being regular if all of its sides and angles have the same measurements.
Given:
From the figure, the lengths of the side of the octagon are equal,
So the angle will also be equal,
And we know that octagon has 8 interior angles and their sum is 360 degrees.
Now for measure of one angle = 360° / 8 = 45°,
Therefore, the magnitude of rotational symmetry of the regular octagon below the marked point is 45°.

The isosceles triangle and the rectangle have equal perimeters. The triangle has x+5 on the left side. On its base it has x. The rectangle has x-1 on the left side. On the bottom, it has x+4.
Answers
Answer:
The value of x is 4.
Step-by-step explanation:
The perimeter of the triangle is the sum of the lengths of all its sides.
The perimeter of the rectangle is twice the sum of the length and the width.
base of triangle = x
two equal sides = x + 5
length of rectangle = x - 1
width of rectangle = x + 4
According to the question,
Perimeter of triangle = perimeter of rectangle
x + x + 5 + x + 5 = 2 ( x - 1 + x + 4)
3 x + 10 = 2 (2 x + 3 )
3 x + 10 = 4 x + 6

Ben asked his 19 classmates whether they were right handed or left-handed. There were five more right handed classmates than left handed classmates. Write a system of equations that can be used to determine how many of Ben’s classmates were right and left handed.
Answers
Answer:
left handed = 7 ; right handed = 12
Step-by-step explanation:
r = right handed
l = left handed
r + l = 19
r = l + 5
If we use substitution method we have:
l +5 + l = 19
2 l = 14
l = 7
r = 7 + 5 = 12
Answers:
The system of equations is
[tex]\begin{cases}y = x-5\\x+y = 19\end{cases}[/tex]
where x and y is the number of right-handed and left-handed people respectively.
The system solves to (x,y) = (12,7)
Interpretation:
There are 12 right-handed people and 7 left-handed people in the class.
=========================================================
Explanation:
x = number of right-handed people
y = number of left-handed people
x and y are positive whole numbers.
There are 5 more right-handed people compared to left-handed people, so we can say x = y+5 which is the same as y = x-5. So you could go for either equation. Let's go for the one where y is isolated.
The second equation to form is x+y = 19 because there are 19 people in the class, and you can only be one or the other (left-handed or right-handed but not both). I'm not considering the possibility anyone is ambidextrous though of course that may happen in a realistic setting.
The two equations then form the system
[tex]\begin{cases}y = x-5\\x+y = 19\end{cases}[/tex]
There are a number of ways we can solve this system. Substitution is possibly the quickest way.
x+y = 19
x+(x-5) = 19 ... replace y with x-5; due to the first equation
2x-5 = 19
2x = 19+5
2x = 24
x = 24/2
x = 12 .... this is the number of right-handed people
y = x-5
y = 12-5
y = 7 .... this is the number of left-handed people
