Maya bought 3 chicken wings for $8.80. If Maya spent $25.30, how many chicken wings did she buy?
Answer:
She bought 8.625 wings
Step-by-step explanation:
We can use a ratio to solve
3 x
------- = ----------
8.80 25.30
Using cross products
3 * 25.30 = 8.80x
75.9 = 8.80x
Divide each side by 8.8
75.9/8.8 = 8.8x/8.8
8.625 = x
She bought 8.625 wings

the cost of 5 pens and 3 rulers is 90p
the cost of 2 pens and 1 ruler is 33p
What is the cost of 3 pens and 2 rulers
The cost of 3 pens will be 27P and the cost of 2 rulers will be 30p.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the cost of 5 pens and 3 rulers is 90p the cost of 2 pens and 1 ruler is 33p. the cost of 3 pens and 2 rulers will be calculated as below:-
From the equations and solve:-
5p + 3r = 90p
2p + r = 33p
5p + 3r = 90p
-6p - 3r = -99p
Cost of one pen P = 9
The cost of the 1 ruler:-
2p + r = 33p
2 x 9 + r = 33
18 + r = 33
r = 33 - 18
r = 15
Cost of 3 pens = 3 x 9 = 27
Cost of 2 rulers = 2 x 15 = 30
Therefore, the cost of 3 pens will be 27P and the cost of 2 rulers will be 30p.

There are four buildings on the Mansfield High School Campus, no three of which stand in a straight line. How many sidewalks need to be built so that each building is directly connected to every other building?
There will be total 6 pathways to directly connect to every other building
It is given that,
There are four buildings on the Mansfield High School Campus with a condition that none of the three can stand in straight line.
We need to find,
The total number of ways through which all the four buildings can be directly connected with each other in such a way that none can stand in straight line
Firstly, Let us consider that the buildings are arranged on the corner points of an imaginary square.
Then the number of ways through which all four buildings can be directly connected is by going straight from one building to other by following the imaginary square boundary lines = 4
the number of ways through which all four buildings can be directly connected is by going diagonally from one building to other by following the diagonal of the imaginary square = 2
Hence, The total number of pathways to directly connect to every other building = 4 +2 = 6

what is the inverse of the function y=5x+30?
The inverse of the function is y = ( 1/5 )x - 6.
An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Consider the function,
y = 5x + 30
To find the inverse of the function we interchange x and y then find the equation for y.
Therefore, after interchanging x and y:
x = 5y + 30
Subtracting 30 from each side of the equation.
x - 30 = 5y + 30 - 30
x - 30 = 5y
Now, dividing the whole equation by 5
( x - 30 ) / 5 = 5y / 5
y = ( 1/5 )x - 30/ 5
y = ( 1/5 )x - 6
Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

to a complete stop?
The car comes to a complete stop when t = 14secs.
What is velocity ?
Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. Put another way, speed is a scalar value, while velocity is a vector.
Given:
velocity v(t) = 0.5t^2 – 14t + 80
Differentiating the equation with respect to t to get the velocity,
we get ,
dv/dt = 2 x .05t - 14

Write a recursive formula for each sequence. 1,4,9,16, . . . . . . .
The recursive formula for sequence 1,4,9,16, . . . is a(n) = 2 a(n-1) - a(n-2) + 2
The recursive formula of a sequence is a formula that relates the nth term of the sequence with the preceding term(s), (n-1)th, (n-2)th, and so on.
The given sequence is: 1,4,9,16, . . .
So, we must ask ourselves:
How can we get 4 from 1?
How can we get 9 from 4 and 1?
and so on.
Notice that:
4 = 1 + 3
9 = 4 + 5
16 = 9 + 7
Notice that the differences (3, 5, 7) increase by 2.
Therefore, we can write:
4 = 1 + 3
= 1 + (1 - 0) + 2
9 = 4 + (4 - 1) + 2 (9 is a(3), and 4 is a(2))
a(3) = a(2) + a(2) - a(1) + 2
= 2 a(2) - a(1) + 2
16 = 9 + (9 - 4) + 2
a(4) = a(3) + a(3) -a(2) + 2
a(4) = 2 a(3) - a(2) + 2

Write an equation in slope-intercept form for each line.
(-4,-1) and (-8,-5)
For each line, an equation in slope-intercept form :
y = (-1/4)x - 2 .
What does intercept mean in terms of slope?Summary of the lesson. The slope-intercept form is just a means of stating a line's equation so that the slope (steepness), as well as y-intercept (where the line crosses the vertical y-axis), as well as y-intercept (where the line crosses the vertical y-axis), are obvious. This form is also known as the y = MX + b form.
In a graph, what are slope as well as intercept?The slope, m, of a line represents its steepness. The slope of something like the line is however termed a gradient, sometimes. A line's y-intercept, b, represents the y-coordinate of something like the point where the line's graph intersects the y-axis.
According to the given data:To begin, use the slope formula to determine the average slope here between two points.
m = (y2-y1)/(x2-x1)
= (-1 - (-4))/ (-4-8)
= 3/(-12)
= -1/4
So the slope is -1/4.
We must now determine the y-intercept. This will be accomplished by converting a single of the points and indeed the slope through into point-slope form of something like a linear equation, which is y2-y1 = m(x2-x1).
Let’s plug in the point (8,-4).
So we get y-(-4) = (-1/4)(x-8) ⇒ y+4
= (-1/4)x + 2 ⇒ y
= (-1/4)x - 2.
So y = (-1/4)x - 2
For each line, write an equation in slope-intercept form y = (-1/4)x - 2.

equilateral triangle from a rectangle.
Find its perimeter.
7.2 cm
13 cm
a) Each side of the square is 9 cm long. b) The perimeter of the shape is 18 cm.
What is perimeter?Perimeter refers to the total length of the boundary or outer edge of a two-dimensional shape.
a) The perimeter of a square is the sum of the lengths of all its sides. Since all sides of a square are equal, we can divide the perimeter by the number of sides to find the length of one side:
Perimeter of square = 4 x Length of one side
36 cm = 4 x Length of one side
Divide both sides by 4:
Length of one side = 36 cm / 4 = 9 cm
Therefore, each side of the square is 9 cm long.
b) To find the perimeter of the shape made by cutting an equilateral triangle from a rectangle, we need to add up the lengths of all its sides.
The length of the rectangle is equal to the length of the base of the equilateral triangle plus the length of one of its sides. Since the equilateral triangle has all sides equal, we can find its length by dividing the length of the rectangle by 2:
Length of equilateral triangle = Length of rectangle / 2
Length of equilateral triangle = 7.2 cm / 2 = 3.6 cm
The perimeter of the equilateral triangle is three times its side length:
Perimeter of equilateral triangle = 3 x Length of one side
Perimeter of equilateral triangle = 3 x 3.6 cm = 10.8 cm
The perimeter of the shape is the sum of the length of all its sides, which is the sum of the length of the rectangle and the perimeter of the equilateral triangle:
Perimeter of shape = Length of rectangle + Perimeter of equilateral triangle
Perimeter of shape = 7.2 cm + 10.8 cm = 18 cm
Therefore, the perimeter of the shape is 18 cm.

Write a function $g$g whose graph represents a translation 5 units up of the graph of $f\left(x\right)=3x$f(x)=3x .
The graph when translated 5 units up is g(x) = 3x + 5.
Consider a parent function f(x),
When translating a function up or down by a value (say b), you let g(x) = f(x) + b
If b is positive your graph is translated up, if b is negative your graph is translated down.
When translating a function to the right or left by a value (say a) you let g(x) = f( x + a).
If a is positive your graph is translated to the left, if a is negative your graph is translated to the right.
Therefore, the function g(x) when the graph of the function f(c) = 3x is translated 5 units upwards will be:

Let us assume, new function is g(x)
Think about the parent function f. (x),
If you want to scale a function up or down by a certain amount, let g(x) = f(x) + b.
Your graph is translated upward if b is positive and downward if b is negative.
Let g(x) Equal f(x + a) when moving a function to the right or left by a certain amount (let's say a).
Your graph will be translated to the left if an is positive and to the right if an is negative.
As a result, when the graph of the function f(c) = 3x is translated 5 units upward, the function g(x) will be as follows:
g(x) = f(x) + 5 (because 5 units up)
We can substitute f(x) value,
