The range of rate at which Nadia could type is given by the inequality equation 27 ≤ x ≤ 37 where x is the number of words per minute
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the total number of words typed per minute be = x
Now , the value of x is calculated by
The number of words Nadia can type = 32 words
The rate of change of words per minute = 5 words
So , Nadia can type 5 words slower or faster
So , the value of x ranges from ( 32 - 5 ) and ( 32 + 5 )
So , the value of x ranges from 27 words per minute to 37 words per minute
The inequality equation is given by
27 ≤ x ≤ 37 , where x is the number of words typed by Nadia per minute
Therefore , the inequality equation is 27 ≤ x ≤ 37
Hence , the range of the inequality equation is 27 ≤ x ≤ 37

Zack sold 3 of his old hockey sticks at Refreeze Secondhand Sports Shop. Before he left, he
spent $25 of his earnings on a used pair of hockey gloves. He had $71 remaining. How much
did Zack receive for each hockey stick?
Submit
$32 for each hockey stick
Step-by-step explanation:
71+25=96
96 divided by 3= 32Zack received $32 for each hockey stick he sold. He earned $96 in total from selling 3 sticks after deducting $25 for gloves, leaving him with $71.
Given that Zack sold 3 old hockey sticks and earned a total amount of money.
He spent $25 of his earnings on a pair of used hockey gloves.
After buying the gloves, he had $71 remaining.
Now, we need to find out how much Zack received for each hockey stick.
Let's assume the amount he received for each hockey stick is "x" dollars.
Total earnings from selling the hockey sticks = Number of sticks sold × Amount received per stick
Total earnings = 3x
Zack spent $25 on gloves and had $71 remaining, so we can write this equation:
Total earnings - Amount spent = Remaining money
3x - 25 = 71
Now we can solve for x (the amount received for each hockey stick):
3x - 25 = 71
Add $25 to both sides:
3x = 96
Divide both sides by 3:
x = $32
So, Zack received $32 for each hockey stick he sold.

to spend on parking and admission. Parking is $19.50, and tickets cost $33.75 per
person, including tax. Which inequality can be used to determine p, the maximum
number of people who can go to the amusement park?
Answer:
Step-by-step explanation:
5.25 + 17.75x ≤ 165
17.75x ≤ 159.75
x = 9 people (Assuming they all fit in one vehicle)
Wish You the Best in your Studies.
The number of people who can enter in the amusement park is 7.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Several buddies want to visit the theme park. They may only spend a total of $280 for parking and entrance. Tickets cost $33.75 per person, including tax, and parking is $19.50.
Let p be the number of people who can enter in the amusement park. Then the inequality is given as,
33.75p + 19.50 ≤ 280
Simplify the inequality, then the value of p is given as,
33.75p + 19.50 ≤ 280
33.75p ≤ 260.50
p ≤ 7.72
Thus, the number of people who can enter in the amusement park is 7.

Answer:
65
Step-by-step explanation:
hello dear!
suppose that y and x are the straight line.
as we know that:
115=y (reason: corresponding sides are equal in parallel lines)
now,
y + x= 180(straight angle)
now we keep the value of y i.e. 115
115+x=180
x=180-115
x=65
as there is parallel lines m and n, the angles between them i.e. corresponding angle are equal to each other .
so therefore, the value of x = 65°

convert the equation 2x - 4y = 16 to slope intercept form
Answer:
y = 1/2x -4
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
2x-4y = 16
Subtract 2x from each side
2x-4y-2x = -2x+16
-4y =-2x+16
Divide each side by -4
-4y/-4 = -2x/-4 +16/-4
y = 1/2x -4
The slope is 1/2 and the y intercept is -4

The domain is the set of x-values for which the equation is true.
Since the maximum time is 12 hours, then the domain is less than or equal to 12.Since time can't be negative or 0, then the minimum is greater than 0. ∴ domain would be 0 < x ≥ 12why did j ernest wilkins jr was the first to do something significant in math

The equation for a line is y = mx + b. where m is the slope and b is the y intercept.
The slope is -1/3 (rise: 1, run: -3)
And the y-intercept is at -4.
So the equation for the line is:
y = -1/3x - 4
And we want all the y values BELOW the line of -1/3x - 4 as well as the values on the line because it’s not dotted. So instead of equals we write:
y <= -1/3x - 4
“Y is less than or equals to -1/3x - 4” where it includes the solutions on the line, as well as any solutions below it.
y <= -1/3x - 4 is the answer

The Merry-Go-Round: On a merry-go-round, 12 horses are evenly spaced on the outside perimeter. It takes four seconds for the fourth horse to reach Abe,starting when the first horse is opposite him. How long will it take the merry-go-round to go around once?
Answer:
1) How does "Abe" relate to the merry-go-round? (The problem doesn't seem to say.)
2) How many people did each person provide for? So how many dozens were brought? How many are in a dozen? So how many cookies were brought?

There are n seats on a merry- go-round. A boy takes n rides. Between each ride, he moves clockwise a certain number of places to a new horse. Each time he moves a different number of places. Find all n for which the boy ends up riding each horse.
2) So if there are n horses, first the boy could move by one place then he could move by n+1 places then by 2n+1 so on and so forth, until he moves (n−2)n+1 places, in which case he'd would have been ridden each horse only one time and taken unique number of steps, which implies that all n's satisfy given condition.

D is on side AB of triangle ABC. We know triangle ABC ~ triangle ACD and angle A = 48 degrees. If BC = CD what is angle B in degrees
Answer:4/6
Step-by-step explanation:
The measure of angle ∠B will be 66 degrees.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
D is on side AB of triangle ABC. We know triangle ABC is similar to triangle ACD and angle A = 48 degrees. If BC = CD.
∠ABC = ∠ACB = x (Isosceles triangle property)
In △ABC, the angle sum is 180°. Then we have
∠ABC + ∠ACB + ∠ABC = 180°
x + x + 48° = 180°
2x = 132°
x = 66°
Then
∠BCA = ∠BCD + ∠DCB = 66°
∠BCD = 66° − 18°
∠BCD = 48°
Now, In ΔBCD, then we have
∠BCD + ∠BDC + ∠DBC = 180°
48° + ∠BDC + 66° = 180°
∠BDC = 66°
We know that ∠BDC = ∠DBC,
∠DBC = ∠BDC
∠DBC = 66°
The measure of angle ∠B will be 66 degrees.
