jontae went to brunch with his family and offered to pay the bill.The total bill was $54.19 before tax. If there is a 15% how much does he pay in taxes
Answer:
$62.32
Step-by-step explanation:

The height of a pebble dropped from a cliff 20,00 feet heigh is described by formula h(t)=20,000 + 5t^2. How long will the pebble take to reach a height of 32,500 feet?
Answer:
It will take 50 seconds for the pebble to reach the height
Step-by-step explanation:
To calculate the time, simple substitute h(t) for 32,500
So we have
32,500 = 20,000 + 5t^2
5t^2 = 32,500-20,000
5t^2 = 12500
t^2 = 12500/5
t^2 = 2500
t = square root of 2500
t = 50 seconds

Rendering math...While solving an equation, Wayra made some mistakes. Her solution is given below. Please help her to identify the step in which there is a mistake and also the right solution. Step 1: 13(z+6) = 4(z-3)-5z Step 2: 13z+19 = 4z-12-5z Step 3: 13z+19 = z-12 Step 4: 13z+z = -19-12 Step 5: 14z =-31 Step 6: z =-3114 Wayra has made a mistake at?
Answer:
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
Step-by-step explanation:
Given the equation solved by Wayra expressed as;
Step 1: 13(z+6) = 4(z-3)-5z
She is find the value of z from the equation;
Step 2: Open the parenthesis using the distributive property;
13(z+6) = 4(z-3)-5z
13z + 13(6) = 4z - 4(3) - 5z
13z + 78 = 4z - 12 - 5z
Step 3: Simplify
13z + 78 = 4z - 5z - 12
13z + 78 = -z -12
Step 4: Collect the like terms;
13z + z = -12 - 78
Step 5: Simplify the result
14z = -90
Step 6: Divide both sides by 14
14z/14 = -90/14
z = 6.428
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z

A cell phone company charges $40 per month for unlimited calling and $0.20 per text message sent. If t represents the number of text messages Roxy sent last month wich expression represents the cost of her bull last month before any taxes or additional fees
Answer:
Total cost = 40 + 0.2t
Step-by-step explanation:
Given:
Fixed cost for call = $40
Each message cost = $0.20
Number of message = t
Find:
Equation of total cost
Computation:
Equation of total cost
Total cost = Fixed cost for call + (Each message cost)(Number of message)

What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given expression is,
f(x) = -4x^2 + 4x - 4
now, we have to find the value of f(3).
so, we have to put x = 3, in the expression.
we get,
f(x) = -4x^2 + 4x - 4
f(3) = -4* 9 + 4*3 -4
or, f(3) = -36 + 12 -4
or, f(3) = -28
Hence, The solution is the value of f(3) = -28.

find the slope of the line passing through (3,7 ) and (6,11) asap
Answer:
4/3
Step-by-step explanation:
You're going to want to use the slope formula which is attached. Using this, you'll take the second y and subtract the first y from it. In other words, 11-7, which is 4. This will be the numerator. Then, you'll take the second x and subtract the first x from it. In other words, 6-3, which is 3. This will be the denominator. The final answer is [tex]\frac{4}{3}[/tex].
Which statement accurately describes the vector shown?
Answer:
magnitude of √61 and a direction angle equal to approximately 40°
Step-by-step explanation:
I inserted the x,y axis into a vector calculator to get the magnitude and angle :D
The magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have a vector shown in the picture.
The coordinate of the vector are:
The tail coordinate = (0, 0)
The head coordinate = (6, 5)
We can find the magnitude of the vector using the distance formula:
The distance formula can be given as:
[tex]\rm M=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm M=\sqrt{(6-0)^2+(5-0)^2}[/tex]
M = √61
The direction of the angle:
tanA = 5/6
tanA = 0.8333
A =39.80 ≈ 40 degrees
Thus, the magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.

For a charity event, raffle tickets are printed such that they have a vowel (excluding y) as the first character and a prime number less than 10 as the second digit. (Note that 1 is not a prime number.) The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is
Answer:
P=5%
Step-by-step explanation:
In order to solve this problem, we can use the following formula for the probability of two independent events:
P(A and B)=P(A)*P(B)
so we need to find the probability for each event to happen.
They are asking for the probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). Therefore the probability for the first letter to be e is:
[tex]P(A)=\frac{desired}{total}[/tex]
[tex]P(A)=\rac{1}{5}[/tex]
We also know there are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
[tex]P(B)=\frac{1}{4}[/tex]
so the probability of getting a ticket that starts with an e and ends with a 5 is:
P(A and B)=P(A)*P(B)
[tex]P(A and B)=(\frac{1}{5})(\frac{1}{4})[/tex]
[tex]P(A and B)=\frac{1}{20}[/tex]
so the probability is 5%
The probability that the winning ticket has the vowel contained in the word event and the digit is the number of letters in the word event is P=5%.
What is probability?The chance of happening an event out of all the possible outcomes is called the probability of an event.
The probability of two independent events
P(A and B)=P(A)*P(B)
The probability that the winning ticket will have the letter e on it. There are 5 vowels in the alphabet (a, e, i, o and u). So, the probability for the first letter to be e is:
P(e) =1/5
There are 4 prime numbers between 0 and 10 (2, 3, 5, 7) so the probability for the number to be a 5 is:
P(B) =1/4
So, the probability of getting a ticket that starts with an e and ending with a 5 is:
P(A and B)=P(A)*P(B)
= 1/5 x 1/4 =1/20
In percentage , probability is 1/20 x 100 % =5%
Hence, the probability is 5%
