Cruise ships in the Jolly Cruise Line charge $14.45 per day for access to their premium WI- Fi. Each minute you use the internet you are charged $0.75. Which equation below represents this situation, if y represents the total amount you are charged for the day and a represents the number of minutes you use the Wi-Fi
y= 14.45x + 0.75
y= 14.45x - 0.75
y= 14.45 - 0.75x
y= 14.44 + 0.75x
Answer:
The equation y = 14.45 + 0.75x represent the situation.
Step-by-step explanation:
Given that:
Cost charged to access the premium wifi = $14.45
Cost charged each minute = $0.75
Let,
x represent the number of minutes
y represent the total amount charged
y = 14.45 + 0.75x
Hence,
The equation y = 14.45 + 0.75x represent the situation.
which table represents a function ? please help quick
Answer:
The first table (the one that has -3 as the first number in the table)
Step-by-step explanation:
A table is a function when the x column doesn't have any numbers repeated.

Step-by-step explanation:
help me asap!!!!
Consider the function, y= 2x – 1
use the above function to complete the following table.
Answer (numbers needed in boxes, going from top to bottom):
1
-1
-3
3
Step-by-step explanation:
f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.
1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:
[tex]y = 2(1)-1\\y = 2 - 1\\y = 1\\[/tex]
So, when x equals 1, y equals 1. Therefore, the first box on the top must be filled out with the number 1.
2) Do the same with the rest of the x values. Here are the steps to solve each one, going in order from the top towards the bottom:
x = 0
[tex]y = 2(0) - 1\\y = 0 - 1\\y = -1[/tex]
x = -1
[tex]y = 2(-1) - 1\\y = -2 -1 \\y = -3\\[/tex]
x = 2
[tex]y = 2(2)-1\\y = 4-1\\y = 3\\[/tex]

Simplify 9xºy-3 Write your answer using only positive exponents.
Answer:
we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]
Step-by-step explanation:
Given the expression
[tex]9x^0y^{-3}[/tex]
Apply exponent rule: [tex]a^{-b}=\frac{1}{a^b}[/tex]
[tex]\:9x^0y^{-3}=9\cdot \:\frac{1}{y^3}x^0[/tex]
Apply rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]=9\cdot \:1\cdot \frac{1}{y^3}[/tex]
Multiply fractions: [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]
[tex]=1\cdot \frac{1\cdot \:9}{y^3}[/tex]
Refine
[tex]=\frac{9}{y^3}[/tex]
Thus, we conclude that:
[tex]\:9x^0y^{-3}=\frac{9}{y^3}[/tex]
Kira had some money sitting in a savings account that earns 2.75% simple interest each year. She left it there for 8 years and earned $495 in interest. How much money did she have in the account to begin with.
Answer:
$2250
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2.75%/100 = 0.0275 per year,
then, solving our equation
I = 2250 × 0.0275 × 8 = 495
I = $ 495.00
The simple interest accumulated
on a principal of $ 2,250.00
at a rate of 2.75% per year
for 8 years is $ 495.00.

Answer:
C. 60%
Step-by-step explanation:
Consider 1st row of table
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
Consider 2nd row of table
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%
Given that p varies jointly as q and r, and p = 7. when q = 2
and r= 1.5, find the following:
a. an equation relating p, q, and r
b. p when q = 4 and r= 6
c. p when p=1 and r=3
d. r when p= 5 and q = 8
Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7
d. P = kqr
5 = 7/3*8*r
5 = (7*8*r)/3
5*3 = 56r
15 = 56r
r = 15/56

Sue bought 2 pairs of jeans and a belt that cost $6.95. The tax on the items was $5.85. Sue paid the cashier $70.00. How much money did Sue receive in change? Write you answer in a complete sentence.
Answer: Sue's change will be $57.20
Step-by-step explanation:
Sue bought 2 pairs of jeans and a belt for $6.95.
Sue also paid a tax of $5.85 for the items.
Sue gave the cashier $70, her change will therefore be:
= 70 - 6.95 - 5.85
= $57.20

Which of the following functions represents f(n), the number of small squares in figure n?
a.f(n)=4n^2+2
b.f(n)=n^2+5
c.f(n)=(n+1)^2+2
d.f(n)=(n+1) (n+2)
Answer:
c. f(n) = (n+1)^2 + 2
Step-by-step explanation:
It is c. because...
f(n) = (1+1)^2 + 2
2^2 + 2
4 + 2 = 6 (first term)
f(n) = (2+1)^2 + 2
3^2 + 2
9 + 2 = 11 (second term)
f(n) = (3+1)^2 + 2
4^2 + 2
16 + 2 = 18 (third term)

Answer: 15.199
Step-by-step explanation:
Using the Pythagorean theorem, we know that a²+b²=c²
In this case, we know that c is 16, and that b is 5.
We can rearrange the equation so that it becomes a²=c²-b²
a²=16²-5²
a²=256-25
a²=231
√a²=√231
a=15.199
I'm not smart and I stink at math so can someone plz help me 12/x = 8
1. We need to get rid of all the denominator in this equation.
This can be done by multiplying left and right sides by the LCD.In the problem: 12/x = 8, the LCD is X.12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
