Answer:
4x + 12 + 2x + 10
Step-by-step explanation:
4( x + 3 ) -2( -x -5 )
1. Multiply 4 and x = 4x
2. Multiply 4 and 3 = 12
3. Multiply -2 and -x = 2x
(turns positive as there are 2 negative signs)
4. Multiply -2 and -5 = 10
(turns positive as there are 2 negative signs)

An airplane is flying at 32,000 feet when it starts it’s decent. It is
descending at a rate of 2000 feet per minute. Let x represent the minutes
of the flights descent and y represent the plane’s altitude.
a. Fill in the table.
b. Write an equation in slope-intercept form for the plane’s altitude.
c. Graph the equation from part (b).
Answers
Answer:
10,000
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000
After five minutes the plane is at 10,000. feet.

Answer:
Well i think that is true. and the mystery number i believe is 11
Step-by-step explanation:
Well, first subtract 5 from 27, you get 22. Then divide that by two (because that is half). And you get 11.
11 · 11 = 22
22 + 5 = 27

A group of friends wants to go to the amusement park. They have $116 to spend on parking and admission. Parking is $10.25, and tickets cost $35.25 per person, including tax. Which equation could be used to determine pp, the number of people who can go to the amusement park?
Answers
Answer:
2 people
Step-by-step explanation:
no. of people = x
total parking costs = 10.25x
total tickets cost = 35.25x
total = 10.25x + 35.25x
suppose 3 people go, then the total cost will be
10.25(3) + 35.25(3) = 136.5 and this is greater than 116
Suppose 2 people go then the cost will be
10.25(2) + 35.25(2) = 91 which is less than 116
so only 2 people can go.

What is the approximate volume of the cylinder, to the nearest tenth of a cubic inch?
(Use 3.14 for pi.)
Answers
Answer:
Volume = 251.2 cubic inches
Step-by-step explanation:
You get the volume of a cylinder by multiplying the area of the base with the height.
Since the diameter is 4 inches, the radius of the base is 4/2 = 2 inches
So, volume = base area* height
= 2² * 3.14 * 20
= 251.2
The approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
Volume of cylinder is the can be given as,
[tex]V=\pi r^2h[/tex]
Here, (r) is the radius of the base of the cylinder and (h) is the height of the cylinder.
A cylindrical mailing tube has a length of 20 inches and diameter of 4 inches. The radius is half of the diameter of the cyilnder. Thus the radius of the cylinder is,
[tex]r=\dfrac{4}{2}\\r=2\rm\; in[/tex]
Put the value of radius and height of the cylinder in the above formula as,
[tex]V=3.14 (2)^2(20)\\V=251.2\rm\; in^3[/tex]
Thus, the approximate volume of the cylinder mailling tube, to the nearest tenth of a cubic inch is 251.2 in³.

Two ferries just departed from their docks at the same time. Ferry A departs every 1.2 hours. Ferry B departs every 1.8 hours. How long will it be until both ferries depart from their docks at the same time again?
Answers
Answer: It will take 36 minutes(0.6 hour) until both ferries depart from their docks at the same time again.
Step-by-step explanation:
Given : Ferry A departs every 1.2 hours.
Ferry B departs every 1.8 hours.
To find : Time taken by both ferries until they depart from their docks at the same time again.
= LCM (1.2, 1.8) hours [LCM= Least common multiple]
= LCM (1.2(60 minutes), 1.8(60 minutes)) [Since 1 hour = 60 minutes]
= LCM (72 minutes, 108 minutes)
72 = 2 x 2 x 2 x 3 x 3 , 108 = 3 x 3 x 3 x 2 x 2
LCM (72,108) =2 x 2 x 3 x 3 =36
So, it will take 36 minutes until both ferries depart from their docks at the same time again.
In hour = [tex]\dfrac{36}{60}\text{ hour}=0.6\text{ hour}[/tex]

How many hours per month must Mr. Demir work at his part-time job to make sure that he and Mrs. Demir have met their monthly budget?
Answers
Answer:
93.75 hours
Step-by-step explanation:
The Demir family has a monthly budget of $5,500. Mrs. Demir works fulltime and takes home $4,000 each month.
Hence, the amount of money Mr Demir is meant to bring at the end of the month is :
Monthly budget - Amount of money that Mrs Demir takes home
= $5,500 - $4,000
= $1,500
From the question, we are told that:
Mr. Demir works part-time and brings home earns $16 per hour. How many hours per month must Mr. Demir work at his part-time job to make sure that he and Mrs. Demir have met their monthly budget?
This is calculated as:
$16 = 1 hour
$1,500 = x
Cross Multiply
16 × x = 1500 × 1
x = 1500 /16
x = 93.75 hours
Therefore, Mr Demir must work for 93.75 hours in a month at his part time job.

What is the value of a length of a triangle within a geometric system?
In this system we find a picture of a geometric system formed by the two triangles, one of which with a right angle. We need to use trigonometric functions, law of sines and law of cosine to determine the missing length. First, use the law of sines:
(129 ft) / sin 33.7° = r / sin 26°
r = 129 ft × sin 26° / sin 33.7°
r ≈ 101.920 ft
Lastly, we find the value of the length h by trigonometric functions:
h = r · sin 59.7°
h = (101.920 ft) · sin 59.7°
h ≈ 87.997 ft
The length h indicated in the figure is approximately 87.997 feet.

How much more interest is earned on an investment of $12,585 at 3.5% interest over 5 years if the interest is compounded annually rather than earning simple interest? a. They are the same. b. $159.65 c. $2,362.03 d. $12,744.65
Answers
$159.65 is earned if compounded annually rather than simple interest.
The simple interest is calculated using the formula:
I = PRT I = 12,585 * 0.035* 5I = $2,202.375For the compound interest
A = P(1+r)^n
A = 12585(1+0.035)^5
A = 12585*1.18768
A =14,946.95
Compound interest = 14,946.95 -12585
Compound interest = $2,361.9528
Taking the difference in the interest = 2,361.9528 - 2,202.375
Difference = $159.65$159.65 is earned if compounded annually rather than simple interest.
Hence the $159.65 is earned if compounded annually rather than simple interest.
