Answer:
1) 120
2) 24
Step-by-step explanation:
This is a problem involving permutations: the number of different ways you can arrange stuff
If there are n items, n! represents the permutation of n and is given by the formula : 1 x 2 x 3 x........x (n-1) x n also sometimes written in the form
n x (n-1) x (n-2) x........x 3 x 2 x 1
In this case there are 5 people. So the number of different ways they can stand in line is 5! = 5 x 4 x 3 x 2 x 1 = 120 ways Answer to (1)
Answer to (2)

plug in the answers to see which has an equal scale factor between mp and mt, and po and tr
if tr = 6, then the scale factor between po and tr is 1.5
that means, that in order to equal 9 mt would have to be 3
if mt = 3, then the scale factor between mp and mt would also be 1.5
therefore, since they both have an equal scale factor, the answer is
4) TR = 6

Answer:

Step-by-step explanation:
convert the decimal number to the base stated
113 to base 6
Answer:
the answer is 341(I think)
113 = 3 • 36 + 5
(That is, 36 = 6² is the largest power of 6 that fits into 113. The next power 6³ = 216 exceeds 113.) Then
113₁₀ = 3 • 6² + 5 • 6⁰ = 305₆

The graph crosses the x-axis at (-2,0)
The graph has a vertical asymptote at r = -3.
The graph has a hole at (3,0).
The graph has a horizontal asymptote at y = 2
The domain of the function does not include the values x= -3 and x= 3.
Answer:look at image
Step-by-step explanation:
The domain of the function does not include the values x = -3 and x = 3 is the only correct option.
What is a function ?"Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences."
This relationship is commonly symbolized as y = f(x)—which is said “f of x”—and y and x are related such that for every x, there is a unique value of y. That is, f(x) can not have more than one value for the same x. To use the language of set theory, a function relates an element x to an element f(x) in another set. The set of values of x is called the domain of the function, and the set of values of f(x) generated by the values in the domain is called the range of the function."
In the graph plotted,
The graph has no y intercept.
Vertical asymptotes is x = 0
No horizontal asymptotes
Slant asymptotes is y = 2x + 3
Hence, F is the True and A, B, C, D, E are false.

O
x=-4 0
Answer:
x = - 2
Step-by-step explanation:
Given
- 1.2x + 2.5 = 0.8x + 6.5 ( subtract 0.8x from both sides )
- 2x + 2.5 = 6.5 ( subtract 2.5 from both sides )
- 2x = 4 ( divide both sides by - 2 )

Find the sum of first 15 terms of an AP whose 4th and 9th t terms are -15 and -30 respectively.
Answer:
Sum of the first 15 terms = -405
Step-by-step explanation:
a + 3d = -15 (1)
a + 8d = -30 (2)
Where,
a = first term
d = common difference
n = number of terms
Subtract (1) from (1)
8d - 3d = -30 - (-15)
5d = -30 + 15
5d = -15
d = -15/5
= -3
d = -3
Substitute d = -3 into (1)
a + 3d = -15
a + 3(-3) = -15
a - 9 = -15
a = -15 + 9
a = -6
Sum of the first 15 terms
S = n/2[2a + (n − 1) × d]
= 15/2 {2×-6 + (15-1)-3}
= 7.5{-12 + (14)-3}
= 7.5{ -12 - 42}
= 7.5{-54}
= -405
Sum of the first 15 terms = -405

Mrs. Haley had 5/7 of a liter of salt water. She used 1/2 of a liter for an experiment. How much salt water does Mrs. Haley have left?
Mrs. Haley had
liters of salt water left
PLEASE HELP SOON!! :))
Answer:
Mrs. Haley had [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.
Step-by-step explanation:
Mrs Haley has salt = [tex]\frac{5}{7}\:liter[/tex]
Mrs Haley used salt = [tex]\frac{1}{2}\:liter[/tex]
We need to find how much salt is left?
[tex]Salt\: left = Total\: Salt - Salt\: used\\Salt\: left = \frac{5}{7}-\frac{1}{2}\\Salt\: left =\frac{5*2-1*7}{14} \\Salt\: left =\frac{10-7}{14} \\Salt\: left =\frac{3}{14}[/tex]
So, Mrs. Haley had [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.

Step-by-step explanation:
a cell phone company charges an initial price of $500 for a new phone and then $60 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? r: (0, 500) r: (60, 560) r: ℝ r: (–[infinity], [infinity])
The range of C(t), the function of the average monthly cost of owning the cell phone, is (60, 560].
The range of a function is the set of all y-values obtained after substituting all possible x-values.
Steps to find the range of a function:
Find the possible domain of the function.For the given problem:
The price of the device = $500
Monthly plan = $60
C(t) is defined as the average monthly cost of owning the phone.
Let t = number of months of owning the cell phone.
Then, total cost after t month = 500 + 60 t.
Hence, the average is:
C(t) = (500 + 60t)/t
C(t) = 500/t + 60
For t = 1, C(1) = 500 + 60 = 560
For t > 1, C(t) < 560
Therefore the maximum value of C(t) = 560
For t →∞ then 500/t will approach zero, hence:
C(t) →(0 + 60), or C(t) will approach 60.
Therefore, we can conclude that 60 < C(t) ≦ 560, or the range of C(t) is (60, 560].

Tyler just lit a new candle and then let it burn all the way down to nothing. The initial
length of the candle was 15 inches and the candle burned at a rate of 1.25 inches per
hour. Write an equation for L, in terms of t, representing the length of the candle
remaining unburned, in inches, t hours after the candle was lit.
Answer: L=
1.25 in/hr is an equation for L, in terms of t, representing the length of the candle remaining unburned, in inches, t hours after the candle was lit.
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.L(t) is a function of time, t: L(t) = 15 in - (1.25 in/hr)t
Note that when the candle has burned down to nothing, L(t) = 0. How long does that take? Set 15 in - (1.25 in/hr)t equal to zero and solve for t:
(1.25 in/hr)t = 15 in, or
15 in
t = ---------------- = 12 hrs
L = 1.25 in/hr

Rebecca is baking three cakes for a big party. If the recipe for one cake calls for 123 cups of flour, how many cups of flour does she need for three cakes?
The total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the recipe for one cake calls for 123 cups of flour. Also, Rebecca needs to bake three cakes, therefore, the total number of cups of flour that Rebecca will need is,
Total number of cups of flour = Number of cakes × Number of cups of flour in a cake
= 3 cakes × 123 cups of flour per cake
= 369 cups of flour
Hence, the total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.

4. Tell if the measures 6, 14, and 13 can be side lengths of a triangle. If so, classify the triangle as acute,
right, or obtuse.
a. Yes; acute triangle
c. Yes; right triangle
b. Yes; obtuse triangle
Answer:
A. Yes; acute triangle
Step-by-step explanation:
a=6
b=14
c=13
Using Pythagorean theorem-
c^2 = a^2 + b^2
13^2 = 6^2 + 14^2
169 = 36 + 196
169 = 232
169 < 232
Therefore, (a) the triangle is acute.
If 169 =169 there would be a right triangle.
If c were greater than a + b there would be an obtuse triangle.
