A dinner cost $28.50 which included a 15% tip. How much was the tip?
Explain the answer please
Answer:
Tip: $4.275 = $4.28
Step-by-step explanation:
Use the formula: Tip = Tip% x Bill Total
In this case, the tip is 15% and the total bill is $28.50.
15% = 0.15
28.50 x 0.15 = 4.275
Round 4.275 to the hundredths, which equals 4.27
Answer: $4.28

Given the speeds of each runner below, determine who runs the fastest.
Stephanie runs 12 feet per second.
Liz runs 306 feet in 38 seconds.
Will runs 1 mile in 491 seconds.
Brooke runs 851 feet in 1 minute.
Answer:
Brooke
Step-by-step explanation:
We can solve this by figuring out how far each person runs a second
Stephanie runs 12 feet a second so nothing needs to be done here
Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet
Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75
Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18
Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Answer:
Step-by-step explanation:
Note the following: 2^4 = 16; (x^3)^4 = x^12; and (y^4)^4 = y^16
Then your 4(2x^3y^4)^4 becomes 4*16*x^12*y^16
Which of the following rates is proportional to $2.50 for 5 cans?
A.$4.50 for 9 cans
B.$1.50 for 1 can
C.$4.00 for 7 cans
D.$2.00 for 3 cans
Answer:
The answer is A. $4.50 for 9 cans
Step-by-step explanation:
Divide 2.50 by 5 and you get $0.50 a can
Multiply $0.50 by each of your answers
A. 0.50 times 9 = 4.50
B. 0.50 times 1 = 0.50
C. 0.50 times 7 = 3.50
D. 0.50 times = 1.50
As you can see A. is the only one that matches

Braxton puts $1,275 into a savings account that earns 3% simple interest per year. How much total money will be in his account after 5 years?
A) $191.25
B) $1,466.25
C) $19,125.00
D) $20,400.00
Answer:
The answer would be B) 1,466.25
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I= P x r x t
Where:
P is the principal amount, $1275.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1275 × 0.03 × 5 to get that:
The interest is: $191.25
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 1275.00 + 191.25 = 1466.25.
Write the following expression in standard form: (7x – 5) – (3x – 2)

the table represent some points on the graph of an exponential function which function represents the same relationship (see image attached)
Answer: Is the second
Step-by-step explanation:
I took the result of the tables of values with the calculator and it gave me the result I regret not being able to give you an explanation
The exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]
An exponential function is represented as:
[tex]y = ab^x[/tex]
Where:
a represents the initial valueb represents the rateFrom the table we have the following ordered pair
(x,y) = {(0,18) (1,21.6)}
So, we have:
[tex]y = ab^x[/tex]
[tex]18 = a \times b^0[/tex]
[tex]a= 18[/tex]
Also, we have:
[tex]y = ab^x[/tex]
[tex]21.6 = a \times b^1[/tex]
[tex]21.6 = 18 \times b[/tex]
Divide both sides by 18
[tex]b = 1.2[/tex]
So, we have:
[tex]y =18 \times 1.2^x[/tex]
Rewrite as:
[tex]y =18 (\frac 65)^x[/tex]
Hence, the exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]
