The operating characteristics of the customer waiting line shows that the average service rate per hour is 5 customers per hour.
How to compute the operating characteristics?The average service rate per hour will be:
= 60/12 = 5
The average number of customers waiting will be:
= (2.2)²/5(5 - 2.2)
= 4.84/14
= 0.3457
The average number of customers in the system will be:
= 0.3457 + 2.2/5
= 0.7857
The average time that a customer spends waiting in the system will be:
= 0.3457/2.2
= 0.1571

Step-by-step explanation:
Louise: Water = 4.6 + 1.2*t gallons of water
Isaac: Water = 54.6 - 0.8 * t t is in minutes.
When will the two amounts of water be equal
When the two waters are the same.
4.6 + 1.2*t = 54.6 - 0.8t Add 0.8t to both sides
4.6 + 1.2*t + 0.8*t = 54.6 Combine the left
4.6 + 2t = 54.6 Subtract 4.6 from both sides.
4.6-4.6 + 2t = 54.6 - 4.6 Combine
2t = 50 Divide by 2
t = 50/2
t = 25
Answer: both aquariums will have the same amount of water in 25 min

Which expression is equivalent to x^2+7x+12 over x^2-x-12
Answer:
Step-by-step explanation:
Factorize the expression.
Sum = 7
Product = 12
Factors = 4 , 3
4 + 3= 7 & 4*3 = 12
x² + 7x + 12 = x² + 4x + 3x + 4*3
= x(x + 4) + 3(x + 4)
= (x + 4)(x + 3)
Sum = -1
Product = -12
Factors = (-4) , 3
(-4) + 3 = (-1) & (-4)*3 = -12
x² - x - 12 = x² - 4x + 3x - 4*3
= x(x - 4) +3(x - 4)
= (x -4)(x +3)
[tex]\sf \dfrac{x^{2}+7x+12}{x^{2}-x-12}=\dfrac{(x+4)(x + 3)}{(x -4 )(x + 3)}\\\\\bf \text{(x +3) in the numerator and denominator will get cancelled}[/tex]

It was reported in 2007 that there were 7,234,000 people age 16 or older who had a "go outside the home" disability and that this was 22.4% of the population (of this age group). These are people who cannot go outside the home without help. How large was the total population (of this age group) in 2007?
Answer:
32294643
Step-by-step explanation:
You can first set up a proportion.
22.4/100 = 7234000/x
723400000 = 22.4x
x = 32294642.8571 ≈ 32294643

[tex] c^{-1}d^7 [/tex]
Step-by-step explanation:
You are multiplying factors with the same base, so add the exponents of the same base.
c^0d^7 × c^-1d^0 = c^0c^-1 × d^7d^0 = c^(0-1)d(7+0) = c^-1d^7
Answer: (dc)⁶
Step-by-step explanation:
Apply exponent rule: a⁰=1
This means c⁰=1 and d⁰=1 leaving the equation d⁷·c⁻¹
This then becomes d⁷/c though since they don't want a denominator we will have to change it.
Apply quotient rule of exponents: aᵇ÷aⁿ=aᵇ⁻ⁿ
This leaves us with (dc)⁶

Write an equation of the circle with center (-5,2) and diameter 6.
Answer:
[tex](x+5)^2+(y-2)^2=36[/tex]
Step-by-step explanation:
The equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius, thus:
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-2)^2=6^2\\(x+5)^2+(y-2)^2=36[/tex]
This means that our equation for the given circle is [tex](x+5)^2+(y-2)^2=36[/tex]

Answer:
One line of symmetry.Both rotational and bilateral symmetry.My reasoning for saying both is because the shape is a unique plane. Bilateral symmetry is the term used for when a unqiue shape is folded in any direction and looks the same, while rotational symmetry is when a shape looks the same after a rotated half-turn.
Trick: Fold the shape by the bottom diagonal left side, folding the top left end, then do a rotational turn on the top right corner, fold in the bottom, and it shapes like a rectangle.
A bookstore has 36 copies of the latest bestseller and they fit exactly on 3 shelves. The bookstore ordered another 120 copies. How many shelves do they need to fit all their copies of the book?
Answer:
13
Step-by-step explanation:
First, to find out how many book fit on one shelf, you will need to divide the total number of books by the toal number of shelves:
36 books / 3 shelves = 12 books/shelf
Because the question says that the bookstore order another 120 copies, this is means that the 120 books is in addition to the original 36 books.
Because we already know that the 36 books require 3 shelves, we still need to find how many shelves 120 books needs. So, we can divide books by number of how many books can fit on a shelf:
120 books / 12 books per shelf = 10 shelves
So to find the total number of shelves needed, add the number of shelves together:
3 + 10 = 13 shelves

Answer:
A. 25 books
Step-by-step explanation:
James has 100 comic books and sells 1/4 of his collection. This means that the amount of comic books that he sold is 1/4 of 100 since 100 is the total amount of comic books that he has. To calculate that, we divide 100 by 4 to get 25. Therefore, James sells 25 books.

Hope it helps you in your learning process.
[tex]7^{\frac{9}{4}}= \sqrt[4]7^{9}\implies\sqrt[c]a^{b}[/tex]
On comparing, we find:
a = 7, b = 9, c = 4
Answer:
[tex] \sf \: a = 7,\: b = 9,\: c = 4[/tex]
Step-by-step explanation:
[tex] {7}^{\frac{9}{4}} [/tex] we have to write in the form [tex] \sf \: {}^{c} \sqrt{ {a}^{b} } [/tex]
[tex] {a}^{ \frac{1}{b} } = {}^{b} \sqrt{a} [/tex]
[tex] {a}^{b} = {a}^{b}[/tex]
from there we can write.
[tex] {7}^{3 \times \frac{1}{4} } = {}^{4} \sqrt{ {7}^{9} } [/tex]
Comparing with [tex] \sf \: {}^{c} \sqrt{ {a}^{b} } [/tex]
c = 4 , b = 9, a = 7
2a+2b=360 degrees
a) a= 60 degrees
b) a = 75 degrees
use algebra to solve for b, find the unknown angles for the parallelogram
Answer:
2a+2b=360
2(60)+2b=360
120+2b=360
2b=360-120
2b/2=240/2 divide by 2
b=120
step 2
2a+2b=360
2(60)+2(120)=360
120+240=360
360=360
part two b)2a+2b=360
2(75)+2b= 360
150+2b=360
2b=360-150
2b/2=210/2
b=105
step 2
2a+2b=360
2(75)+2(105)=360
150+210=360
360=360
a bathing suit is on sale for 40% off including 7% sales tax the final price is $57.78 what was the original cost without tax or discount
Answer:
38.7126
step-by-step explanantion:
so it's technically 33 percent off because the taxes is 7 percent.
and 33 percent of 57.78 is 19.0674. so 57.78-19.0674 will equal 38.7126
The original cost of the bathing suit without tax or the discount is $38.72.
DiscountThe term "discount" refers to a pricing scheme in which a commodity's (goods or services) price is lower than its marked price. Simply said, a discount is a proportion of the advertised price.
How to find the original cost?The bathing suit is 40%off including 7% tax.This means that the discount of 40% includes the tax of 7%.Thus the discount without tax will be calculated by: 40%-7%=33%
Now we will calculate the discount without tax on the final cost of the bathing suit, i.e, 33% of the final cost.
[tex]\frac{33}{100} \times 57.78=19.06[/tex]
So, we get a discount of $19.06 on the final cost.Then the original cost of the bathing suit without the tax or the discount will be the final cost less than the discount: $57.78-$19.06=$38.72
So, the original cost of the bathing suit without tax or the discount is $38.72.
