a rectangular shape waiting room has an area 120ft and a perimeter of 44 ft.what are the dimensions?
Answer: W * L = 120
2W + 2L = 44
2W = 44 - 2L
W = 22 - L
(22-L) * L = 120
22L - L² = 120
L² - 22L = -120
L² - 22L + 121 = 121 - 120
(L - 11)² = 1
L - 11 = ±1
L = 11 ± 1
L = 10 or 12
Dimensions: 10 * 12

If five less than y is six more than x + 1, then by how
much is x less than y?
Answer:
12 more
Step-by-step explanation:
y-5= 6+ (x+1)
5+6+1=12
x is 12 less than y.
Five less than y is six more than x + 1,
y - 5= 6 + (x + 1)
5 + 6 + 1 = 12.

Why is√5 irrational?
A.)because it is less than one
B.)because it has no opposite
C.)because all square roots are irrational
D.)because it cannot be expressed as a ratio of integers
Answer: The expression x(x + 1) is even for any integer x (since either x or x + 1 is even). So this says that 5 × even + 1 = even, or odd = even. Since there is no integer that is both even and odd, we have reached a contradiction and √5 is irrational. So the answer would be D.) because it cannot be expressed as a ratio of integers
The population of a colony of bacteria can be modeled by the function P(t) = 19,300(5)^t, where t is the elapsed time
in hours. What is the inverse function?
Answer:
C. P–1(t) = log5 (StartFraction t Over 19,300 EndFraction)
Step-by-step explanation:
The inverse function of P(t) is [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex]
What is an inverse function?The inverse function is a function obtained by reversing the given function. An inverse is a function that serves to “undo” another function. The domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function.
For the given situation,
The function P(t) = 19,300(5)^t, where t is the elapsed time in hours.
Steps to find inverse function:
Step 1: Replace P(t) as y
[tex]P(t) = 19,300(5)^t[/tex]
⇒ [tex]y= 19,300(5)^{t}[/tex]
Step 2: interchange t and y
⇒ [tex]t = 19,300(5)^y[/tex]
Step 3: Now solve for y
⇒ [tex]\frac{t}{19300} =5^y[/tex]
By law of logarithm,
[tex]a^{x} = y[/tex]
⇒ [tex]log_{a} y=x[/tex]
Thus the equation becomes,
⇒ [tex]log_{5} \frac{t}{19300}=y[/tex]
Step 4: Now replace y as [tex]P^{-1}( t)[/tex]
⇒ [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex]
Hence we can conclude that the inverse function of P(t) is [tex]P^{-1} (t)=log_{5}( \frac{t}{19300})[/tex].

The measure of an angle is 103°. What is the measure of its supplementary angle?
Answer:
77
Step-by-step explanation:
Let's let the unknown number be x.
Supplementary angles add up to a total of 180 degrees. Since we already know one angle is 103, this means that:
[tex]103+x=180[/tex]
Subtract 103 from both sides:
[tex]x=77\textdegree[/tex]
So, the measure of its supplementary angle is 77 degrees.
And we are done!

Customer arrivals at a bank are random and independent; the probability of an arrival in any one-minute period is the same as the probability of an arrival in any other one-minute period.
A. What is the probability of exactly three arrivals in a one-minute period?
B. What is the probability of at least three arrivals in a one-minute period?
Answer:
0.2240418 ; 0.57681
Step-by-step explanation:
Given the information above :
A) What is the probability of exactly three arrivals in a one-minute period?
Using poisson probability function :
p(x ; m) = [(m^x) * (e^-m)] / x!
Here, m = mean = 3, x = 3
P(3 ; 3) = [(3^3) * (e^-3)] / 3!
P(3;3) = [27 * 0.0497870] / 6
= 1.3442508 / 6
= 0.2240418
B) What is the probability of at least three arrivals in a one-minute period?
Atleast 3 arrivals
X >= 3 = 1 - [p(0) + p(1) + p(2)]
P(0 ; 3) = [(3^0) * (e^-3)] / 0! = (1 * 0.0497870) / 1 = 0.0497870
P(1 ; 3) = [(3^1) * (e^-3)] / 1! = (3 * 0.0497870) / 1 = 0.1493612
P(2 ; 3) = [(3^2) * (e^-3)] / 2! = (9 * 0.0497870) / 2 = 0.2240418
1 - [0.0497870 + 0.1493612 + 0.2240418]
1 - 0.42319 = 0.57681

We have three parts of the equation with a power:
x^2y, 5xy^3, and 7y^2
We can find the degree of each by the following:
x^2y; 2 + 1 = 3
5xy^3; 1 + 3 = 4
7y^2; 2
Therefore, the highest degree is 4.

for a medical office complex. There are 36 people on the payroll. Eight people earn $10 per hour, eleven people earn $15 per hour, four people earn $18 per hour, six people earn $21 per hour, and seven people earn $26 per hour. If everyone works 40 hours per week, what is the total amount of money needed for the payroll each week?
Answer:
$25,000
Step-by-step explanation:
8 x $10 = 80 x 40 = $3,200
11 x $15 = 165 x 40 = $6,600
4 x $18 = 72 x 40 = $2,880
6 x $21 = 126 x 40 = $5,040
7 x $26 = 182 x 40 = $7,280
3200 + 6600 + 2880 + 5040 + 7280 = $25,000

A pyramid has a square base with an area of 169ft. What is the perimeter of the base of the pyramid?
Answer:52 ft.
Step-by-step explanation: If the area of the base of the pyramid is
169
ft
2
then each side of the base is
13
ft
long because the base of the pyramid is a square.
Length of the side,
s
=
√
169
=
13
Iif we take the area of a square
A
=
s
2
where
s
=
13
we get the area of the base to be
169
ft
2
thus proving that each side of the base is
13
ft
long.
So to find the perimeter of the base of the pyramid we use the formula:
P
=
4
s
where
s
=
13
ft
and thus,
p
=
4
⋅
13
ft
=
52

On a coordinate plane, a line goes through points (0, 1) and (3, negative 1). Consider the graph of the line. Using the rise/run counting method, the slope of the line is .
Answer: The slope of the line is -2/3.
Step-by-step explanation:
How I think of it is that on the y plane on a graph, going from positive 1 to negative 1 you need to move down 2 places and thats the "rise" part of rise over run eventhough you moved down. Then on the x plane, going from 0 to 3 you need to move 3 spaces to the right on the graph and thats the "run" part of rise over run because you can either move left or right. Rise over run can also be thought of as change in y over change in x which means that since i went down 2 places on the y, the change in y was 2 and since we moved 3 places over on the x plane the change in x whould be 3. Since we move down and then to the right on the graph, the line being created would be negative, so you final answer for the slope is -2/3!

hanks pickup can travel 68 miles on 4 gallons of gas. How many gallons will hanks pickup need to travel 34 miles?
Answer: This is a ratio of miles (m) per gallon (g), which can be written as the fraction m/g. So Hank's truck can do 68 miles per 4 gallons, or 68/4. The other ration of miles per gallon is 34 miles to (x) amount of gallons. If you set these ratios equal to each other, the resulting equation can help you solve for the number of gallons.

If B is the midpoint of AC. AB = 4v and AC = 5v + 24. what is BC?
Answer:
v+24
Step-by-step explanation:
I first drew a line with A in one side and C in the other side. Then, I put B in the middle, as it is the midpoint. Under AB, I put 4v, and under AC, I put 5v+24. To get BC, you must subtract 5v+24 and 4v. I did 5v+24-4v. All I really had to do was subtract 4v from 5v which gave me v, since I can only subtract like-term numbers. Anyway, after that, I got v+24.

Answer:
105 points.
Step-by-step explanation:
The scores of team A and B is 16 and 21.
if 16 = 80, The ratio of 16 to 21 is 5.
So, that means 16 x 5 is 80.
How many points did team B get?
score x gap between 16 to 21
= 21 x 5 = 105.
the team B got 105 points.
