Write the equation of a line that is parallel to the y axis and passes through the point (-2,5).
Answer:
x = -2
Step-by-step explanation:
If it’s parallel to the y-axis, it must be an x value that is straight up and down. The x coordinate here is -2 so the line must be vertical from -2 on the x-axis.
10) 9 people can paint a bridge in 5 hours,
How long would it take 2 people to paint the bridge?
Question 1.
Step-by-step explanation:
The number of people to paint the bridge is inversely proportional to the number of hours it takes.
(If there are more people, it will take less time etc.)
9 people can paint the bridge in 5 hours.
=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.

Linda bought 63 pairs of gloves, which were on sale with a promotion of "buy 4 get 1 free." If each pair of gloves cost $14.50, how much money did Linda spend on all the gloves?
Answer:
$739.50
Step-by-step explanation:
Linda brought =63 pairs of gloves
when she brought 4 she actually got 5 by "buy 4 get 1 free." offer.
This means she got 60/5 = 12 pairs for free out of 63 pairs.
So, she had to pay for only = 63-12 =51 pairs
Therefore, money did Linda spend on all the gloves =51*14.50 = $739.50
Your hotel sells four types of rooms: double queen beds for $120/night; king bed for $140/night; junior suite for $210 and luxury suite for $320. Your accountant advises a 3% increase on all rooms. What will the new average room rate be? Assume an equal number of rooms for each room type
a) $120
b) $197
c) $203
d) $220
Answer:
its b lol
Step-by-step explanation:
Answer is 203.
Average:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
Given,
For double queen beds increment is $120 x 3% => $120 x (3/100) => 3.6.
The total rate for double queen beds = $120 + $3.6 = $123.6
For king beds increment is $140 x 3% => $140 x (3/100) => 4.2
The total rate for double queen beds = $140 + $4.2 = $144.2
For junior suite increment is $210 x 3% => $210 x (3/100) => 6.3
The total rate for junior suite = $210 + 6.3 = $216.3
For luxury suite increment is $320 x (3/100) => 9.6
The total rate for luxury suite = $320 + 9.6 = $329.6
The average rate = ($123.6 + $144.2 + $216.3 + $329.6) / 4
=> $203.425 i.e., $203

Answer:
P = 50,000
r = 0.08
i = 0.02
K = 4
n = 20
t = 5
Step-by-step explanation:
In this formula, r is the annual interest rate, 8% or 0.08. K is the number of times the interest is compounded in a year. Since interest is compounded quarterly, K = 4.
r = 0.08
i = r/K = 0.08/4
i = 0.02
t is the number of years interest is compounded, so ...
t = 5
n = Kt = 4·5
n = 20
P is the principal amount invested:
P = 50,000
A garrison of 120 people had enough food for 30 days. If 20 people leave the garrison after 10 days, how long do the remaining provisions last?
Answer:
We know that no. of days is inversely propotional to the provision for men.
So for 120 men the provision would last for 30days. (given)
Therefore, the provision for 1 men would sustain for. 120 *30 = 3600 days.
Let after the joining of 5 men (after 5 days) the no of more days the provision would last is x days
A.t.q 120*30 = 120*5+125*x
(120*30) - (120*5)= 125x
120(30-5)=125x
120 * 25 = 125x
120 = 5x
x=120/5
x= 24
so the provision would remain for more 24 days.
A retail outlet offers a retention bonus for each shopping season an employee remains with the company. Samuel's starting pay is $12.50/hr. For each season Samuel remains with the company, he receives a $0.35/hr raise. Find f(n), Samuel's hourly rate after n seasons with the company. Then determine his hourly rate after 18 seasons. f(n)= After 18 seasons with the company, what will Samuel's hourly rate will be $ /hr. (Round to the nearest cent.)
Answer:
Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n. After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.
Step-by-step explanation:
You know that Samuel's starting pay is $12.50/hr and for each season Samuel remains with the company, he receives a $0.35/hr raise.
Samuel's hourly rate after n seasons at the company will then be:
f(n)= 12.50 + 0.35*n
To determine the hourly rate after 18 seasons, you must replace the value n with 18:
f(18)= 12.50 + 0.35*18
Solving you get:
f(18)= 12.50 + 6.3
f(18)= 18.8
Samuel's hourly rate after n seasons with the company is f(n)= 12.50 + 0.35*n. After 18 seasons with the company, Samuel's hourly rate will be 18.8 $ /hr.

Sam rented a truck for one day. There was a base fee of $15.99, and there was an additional charge of 97 cents for each mile driven. Sam had to pay $187.68
when he returned the truck. For how many miles did he drive the truck?
Answer:
177
Step-by-step explanation:
First you must subtract the base fee from the total amount of the bill:[tex]187.68 - 15.99= 171.69[/tex]
Then divide the remaining amount of the bill by the charge of .97 cents per mile:[tex]171.69/.97=177[/tex]

question 3 please :) (exact values)
Answer:
(a) h = 160 - 5·x
(b) V = 4·x² × h = 4·x² × (160 - 5·x) = 640·x² - 20·x³ = 20·x²·(32 - x)
∴ V = 20·x²·(32 - x)
Step-by-step explanation:
(a) The given dimensions of the cuboid (rectangular prism) are;
'4·x' meters by 'x' meters by 'h' meters
Let the 4·x meters represent the length, 'l', of the cuboid, let the x meters represent the width, 'w', of the cuboid, and let the h meters represent the height 'h' of the cuboid
Therefore, we are given that the cuboid is a wire cage, with the total length of the sides (edges) of the cuboid equal to 640 meters
Therefore, the sum of the edges are;
Top(4·x + x + 4·x + x) + Side(h + h + h + h) + Bottom(4·x + x + 4·x + x) = 640
20·x + 4·h = 640
∴ h = (640 - 20·x)/4 = 160 - 5·x
h = 160 - 5·x
(b) The volume of a cuboid, V, is given as follows;
V = The area of the base of the cuboid × The height of the cuboid
The area of the base of the cuboid = l × w = 4·x × x = 4·x²
The height of the cuboid = h = 160 - 5·x
∴ V = 4·x² × (160 - 5·x) = 640·x² - 20·x³
V = 640·x² - 20·x³ = 20·x²·(32 - x)
∴ V = 20·x²·(32 - x) QED.

For a filed trip the school bought 47 sandwiches for $40.60 each and 39 bags of chips for $1.25 each. How much did the school spend in all?
Answer:
$1,956.95
Step-by-step explanation:
The school bought 47 sandwiches for $40.60
= 47 × 40.60
= 1,908.2
They also bought 39 bags of chips for $1.25
= 1.25×39
= 48.75
Therefore the total amount spent can be calculated as follows
= 48.75 + 1,908.2
= 1,956.95
Hence the total amount spent by the school is $1,956.95

Answer:
A. 5
Step-by-step explanation:
use pythagorean theorem: a^2 + b^2 = c^2
but since we are finding the value of A; we'll use a= (square root) c^2 - b^2
A= 13^2- 12^2
A= 169 - 144
A= 25
A= 5 ( because we square root 25)
