our equation is 17.75-2x (17.75 is our total, 2 is the price of one notepad, and x is how many we bought, aka what were solving for)
The required number of notepads purchased is given as 7.
Given that,
You bought a magazine for $3.75 and some notepads for $2 each. You spent a total of $17.75, how many notepads did you buy is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
let the number of the notepads purchased be x,
According to the question,
3.75 + 2x = 17.75
2x = 17.75 - 3.75
x = 14/2
x = 7
Thus, The required number of notepads purchased is given as 7.

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 50 total rooms. Joe had already reserved and paid for 16 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 8 rooms and costs $900
Answer:
He is going to pay 40*900= $36000 for the reservationStep-by-step explanation:
Step one:
We are told that they need at least 50 total rooms.
Joe has paid for 16 rooms since Joe can only reserve rooms in block, and a block has 8 rooms, then Joe has paid for 2 blocks.
There is a deficit of 50-16= 34rooms
Required
The Number of blocks Joe need to reserve in addition is 34/8
=4.25
The blocks can not be in decimal, so we need to approximate, which is 5 blocks
Therefore Joe is going to reserve 5*8= 40 rooms
He is going to pay 40*900= $36000 for the reservation

Round 243.583 to the nearest tenth *
Answer: 243.6
Step-by-step explanation:
For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.
Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.

I need help ASAP
Answer:
The slope is 1
Step-by-step explanation:
Slope can be found using the expression [tex]\frac{y2-y1}{x2-x1}[/tex]
In this case,
y2 = 3
y1 = 1
x2 = 6
x1 = 4
[tex]\frac{3-1}{6-4}[/tex] = 2/2 = 1

Find the equation of a line that passes through points A and B.
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2, 3)
m = = = 2, thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using B(2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
If the terminal side of an angle falls in quadrant IV, then the secant value is?
zero
positive
negative
Answer:
it is positive
Step-by-step explanation:
Secant is just sec which is positive in quadrant 4
If the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .
What is quadrant ?Quadrant is a region defined by the two axes ([tex]x[/tex]-axis and [tex]y[/tex]-axis) of the coordinate system. When the two axes, [tex]x[/tex]-axis and [tex]y[/tex]-axis, intersect each other at [tex]90 ^0[/tex], the four regions so formed are the quadrants. These regions include both positive and negative values of [tex]x[/tex]-axis and [tex]y[/tex]-axis, called coordinates.
We know that,
In trigonometry, trigonometric functions i.e. Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cosecθ, the sign of value of all these trigonometric functions varies in every quadrant.
In first quadrant Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cotθ are positive.
In second quadrant Sinθ and Cosecθ are positive.
In third quadrant Tanθ and Cotθ are positive.
In fourth quadrant Cosθ and Secθ are positive.
So, from the above statements we can say that the value of secant in quadrant [tex]IV[/tex] is positive .
Hence, we can say that if the terminal side of an angle falls in quadrant [tex]IV[/tex], then the secant value is positive .

Find the area of a rhombus whose side is 5 cm and whose altitude is 8cm. If one of its diagonals is 10 cm long, find the length of the other diagonal.
Answer:
8 cm
Step-by-step explanation:
Given that:
Side = 5cm
Altitude = height = 8cm
Diagonal 1 = 10cm
Diagonal 2 = d
Area of rhombus = base * height = 0.5 * (diagonal 1 * diagonal 2)
5 * 8 = 0.5 * (10 * d)
40 = 5d
Divide both sides by 5
40/5 = 5d / 5
8 = d
Length of other diagonal = 8cm
