Count the total number of permutations of the word "calculus": there are 8 letters, hence 8! = 40,320 total permutations.
Count the number of permutations in which the two L's occur next to each other. Effectively we're now talking about words consisting of 7 letters, of which there are 7! = 5,040.
It follows that there are
8! - 7! = 35,280
words in which two L's do not appear next to each other.

Friends have a party. Joyce invited 17 friends to a dinner party at her house last Friday
evening. She gave each guest a card with a number from 2 through 18, reserving the
number 1 for herself. When she had everyone paired off at the dinner table, she noticed
that the sum of each couples' number was a perfect square. What number did Joyce's
partner have?
Answer:
15
Step-by-step explanation:
Joyce reserved number 1 for herself
Of all the possible combinations,
1 and 15 is a perfect match for a perfect square
So,Joyce dinner partner was number 15.
If 35% of a number is 21 and 90% of the same number is 54, find 55% of that number.
How do you do this on Delta Math?It is for 7th grade math.
Answer:
Step-by-step explanation:
The number is 60:
Divide the amount and decimal of the percentage to be extracted
Case 1
[tex]\frac{21}{0.35} =60[/tex]
Case 2
[tex]\frac{54}{0.9} =60[/tex]
Now the 55% of this number is:

he following diagram, the ship is anchored to the ocean floor. The length of the rope attaching the
o the boat is 30m. The angle of elevation from the anchor to the ship is 39 degrees. Determine, to th
meter, the distance from the ship to the ocean floor
Determine, to the nearest meter, the distance o
rom the anchor to where the boat is perpendicular to ground.
The distance between the boat and the ocean's floor is 19m
How to get the distance from the ship to the ocean's floor?
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.

Given the following acceleration function of an object moving along a line, find the position function with the given initial velocity and position
a(t) = -40, (O) = 18, S(O) = 0
The position function for the given object is:
s(t) = (-20 m/s^2)*t^2 + (18m/s)*t
How to get the position function?
Here we know that:
a(t) = -40 m/s^2
v(0) = 18 m/s
s(0) = 0m
So, we know the acceleration, the initial velocity, and the initial position.
To get the velocity equation we need to integrate the acceleration equation, we will get:
v(t) = (-40 m/s^2)*t + C
Where C is the constant of integration, which we know that is the initial velocity, then:
v(t) = (-40 m/s^2)*t + 18m/s
Now, to get the position equation, we need to integrate again:
s(t) = (1/2)*(-40 m/s^2)*t^2 + (18m/s)*t + s(0)
s(t) = (-20 m/s^2)*t^2 + (18m/s)*t
So, the position function, is: s(t) = (-20 m/s^2)*t^2 + (18m/s)*t

Glven: 3x + y = 1.
Solve for y.
y = 3x - 1
O y=-3x - 1
O y=-3x+1
Answer:
y = -3x + 1Step-by-step explanation:
3x + y = 1
⇔ -3x + 3x + y = -3x + 1 (we added -3x to both sides of the equation)
⇔ y = -3x + 1 ( because -3x + 3x = 0)

Solve a+2b=12 for b
Help please
Answer:
Add '-2b' to each side of the equation.
a + 2b + -2b = 12 + -2b
Combine like terms: 2b + -2b = 0
a + 0 = 12 + -2b
a = 12 + -2b
Simplifying
a = 12 + -2b
Answer: b= 6-a/2
Step-by-step explanation:
Always try to isolate what you are looking for.
a+ 2b=12 (subtract a)
2b= 12-a (divide by 2 to isolate b)
b= 12-a/2 (divide both numbers by 2 to get the smallest fraction)
b= 6-a/2 [b is now isolated :) ]

What is an equation of the line that is parallel to y = 5- 3x and passes through (0, 2)?
Linear equations are often organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = y-intercept (the value of y when x=0)Parallel LinesParallel lines always have the same slopes and different y-intercepts.
Solving the QuestionWe're given:
The line [tex]y=5-3x[/tex]We must solve for a parallel line that passes through (0,2)Firstly, rearrange the given line in slope-intercept form:
[tex]y=-3x+5[/tex]
Remember, parallel lines always have the same slope. Therefore, our parallel line would look like this, with a (currently) unknown y-intercept (b):
[tex]y=-3x+b[/tex]
We're given that the line passes through the point (0,2). Because the y-intercept occurs when x=0, we now know that the y-intercept of the line is 2. Plug this into the equation:
[tex]y=-3x+2[/tex]
