Answer:
32.
Step-by-step explanation:
The first 32 have buttons but NO zips.
Then 35 have NEITHER buttons OR zips.
Then 32 have ZIPs, but no buttons.
The question only asks for zips. The other bag is unaccounted for.

PLEASE HELP!! solve |2x-2| ≥6.
x ≤ -2 OR x ≥ 4
__________________________________________________________
Step-by-step explanation:We are given the inequality:
|2x - 2| ≥ 6
Getting rid of the Modulus:
Since 2x-2 is in modulus:
|2x-2| = -(2x-2) OR 2x-2
(since the modulus of both these values is 2x-2)
Hence, our inequality can be written in 2 different ways:
2x-2 ≥ 6 (if 2x-2 ≥ 1)-(2x - 2) ≥ 6 (if 2x-2 < 0)__________________________________________________________
Solving these 2 inequalities:
Solving inequality 1:
2x - 2 ≥ 6
2x ≥ 8 [adding 2 on both sides]
x ≥ 4 [dividing both the sides by 2]
This is the solution of the inequality if: 2x-2 ≥ 0
Solving Inequality 2:
-(2x-2) ≥ 6
It can be rewritten as:
2 - 2x ≥ 6
2 ≥ 6 + 2x [adding 2x on both the sides]
-4 ≥ 2x [Subtracting 6 from both sides]
x ≤ -2 [Dividing both sides by 2]
This is the solution of the given inequality if: 2x-2 < 0
__________________________________________________________
Solution of the given Inequality:
Therefore, the solution of the given inequality |2x-2| ≥ 6 are:
x ≥ 4 (if 2x-2 ≥ 0)
x ≤ -2 (if 2x-2 < 0)
Hence, option C is correct!

A person 6ft tall stands 10ft from point P directly beneath a lantern hanging 30 ft above the ground. The lantern start to fall, thus causing the person shadow to lengthen(L). Given that the lantern falls 16t2 feet in t seconds, how fast will the shadow be lengthening when t=1
Answer:
[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]
Step-by-step explanation:
In order to solve this it is always a good idea to start by drawing a diagram of the situation (See attached picture).
From the diagram we can see that we are dealing with similar triangles. We can use similar triangles to build an equation that relates the length of the shadow with the height of the lamp, so we get:
[tex]\frac{L}{6}=\frac{10+L}{h}[/tex]
the height of the lamp can be found by subtracting the [tex]16t^{2}[/tex] distance the lamp falls in a given time t from the original 30ft the lamp was located at.
So the equation will now lok like this:
[tex]\frac{L}{6}=\frac{10+L}{30-16t^{2}}[/tex]
So now we can solve the equation for L, we can start by multiplying by the LCD SO WE GET:
[tex]L(30-16t^{2})=6(10+L)[/tex]
next, we can distribute the right side of the equation so we get:
[tex]L(30-16t^{2})=60+6L[/tex]
and subtract 6L from both sides so we get:
[tex]L(30-16t^{2})-6L=60[/tex]
and factor L, so we get:
[tex]L(30-16t^{2}-6)=60[/tex]
and solve for L:
[tex]L=\frac{60}{24-16t^{2}}[/tex]
now, we can differentiate this equation by using the chain rule, so we get:
[tex]dL=-\frac{60}{(24-16t^{2})^{2}}(-32t)dt[/tex]
which can be simplified to:
[tex]\frac{dL}{dt}=\frac{1920t}{(24-16t^{2})^{2}}[/tex]
and now we can substitute t for 1s so we get:
[tex]\frac{dL}{dt}=\frac{1920(1)}{(24-16(1)^{2})^{2}}[/tex]
[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]

Step 2: Find slope m

Answer:
The domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.
Step-by-step explanation:
From the graph, it is clear that the graph is heading towards positive infinity from x=-4.
The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.
i.e. [-4, ∞)
Hence, the domain of the graph must be [tex]x\ge \:-4[/tex].
Therefore,
[tex]x\ge \:-4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\ge \:-4\:\\ \:\mathrm{Interval\:Notation:}&\:[-4,\:\infty \:)\end{bmatrix}[/tex]
Hence, option a is true.

Which is the height of the lighthouse?
Answer:
Step-by-step explanation:
tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)
sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)

PLEASEEEE HELP AND SHOW WORK WILL GIVE BRAINLIEST... LOVE Y'ALL!!! The time it takes to fly from Los Angeles to New York varies inversely as the speed of the plane. If the trip takes 5 hours at 950 km/h, how long would it take at 850 km/h?
Answer:
4 hour
Step-by-step explanation:
The time it takes to fly from Los Angeles to New York varies inversely as the speed of the plane i.e.
[tex]t\propto v^2[/tex]
Here, t₁ = 5 h, v₁ = 950 km/h, v₂ = 850 km/h, t₂=?
[tex]\dfrac{t_1}{t_2}=\dfrac{v_1^2}{v_2^2}\\\\t_2=\dfrac{t_1v_2^2}{v_1^2}\\\\t_2=\dfrac{5\times (850)^2}{(950)^2}\\\\t_2=4\ h[/tex]
If the speed is 850 km/h then the time is 4 h.

If the parallel lines m and n are 6 units apart, how many units of translation is equivalent to the composition of two reflections over lines m and n?
9514 1404 393
Answer:
12 units
Step-by-step explanation:
Reflection over two lines x units apart is equivalent to a translation of 2x units. Since the given lines are 6 units apart, ...
the equivalent translation is of 12 units.
___
Example:
Lines at x=0 and x=6. Point (x, 0). After reflection over x=0, the point is located at (2·0 -(x), 0) = (-x, 0). After reflection of that over x=6, the point is located at (2·6 -(-x), 0) = (12 +x, 0). That is, 12 has been added to the x-coordinate, meaning the point was translated 12 units. (The translation is in the direction the second line is from the first.)

Number 7 thanks ASAP ASAP
Answer:
Price is $1088 (agrees with answer B)
Step-by-step explanation:
Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;
Price = 12 x + 80
where "x" is the number of computers shipped.
Then, to ship 84 computers, we have the following price:
Price = 12 (84) + 80 = 1088
Then the price is $1088.

Here [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of the segment.
Length of AY = Distance between (-1, 4) and (3, 6)

What is mathematical expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mathematical expression is,
⇒ √x + 20 = 9
Now,
Solve the expression for the value of x as;
The mathematical expression is,
⇒ √x + 20 = 9
Take square on both side, we get;
⇒ (√x + 20 )² = 9²
⇒ x + 20 = 81
Subtract 20 both side, we get;
⇒ x + 20 - 20 = 81 - 20
⇒ x = 61
Therefore, The value of x will be 61.
