Answer:
Step-by-step explanation:
If the equation is going off of what is the traditional, and correct way to tip, the tip would be based off the total BEFORE tax.
Therefore, the expression for the total cost would be: x + .23x +.08x, which, simplified, would be 1.33x.

Answer:
Step-by-step explanation:
Answer: "450" - "0.3" x
Step-by-step explanation: the quantity of 3 tenths is 3/10, or in other words, 0.3 because 3 divided by 10 is 0.3

Find the value of the expression
96 (32÷n÷ 2)-s-t^r
for n = 4, r = 3, s = 9, and t = 2.
Answer:
1,519
Step-by-step explanation:
96 ( 32 ÷ n ÷ 2 ) –s –t^r
since n = 4, r = 3, s = 9, and t = 2. we will just substitute for the values like this
96 ( 32 ÷ (4 ÷ 2) ) –9 ( –2³)
96 ( 32 ÷ 2 ) –9 –8
96 ( 16 ) –17
=1,536 –17

The formula for the perimeter of a rectangle is P = 2l + 2w. Solve the
formula for w in terms of P and l.
Answer:
P-2l/2=w
Step-by-step explanation:
P = 21 + 2w
Solve for w
Subtract 21 from both sides.
P - 21 = 2w
Divide both sides by 2.
P-21/2 = w

According to Newton's Law of Cooling, if a body with temperature T₁ is placed in surroundings with temperature To, different
from that of T₁, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = To + (T₁-To)ekt
A metal pan with temperature 120°F is placed in a freezer with temperature 0°F. After 5 minutes, the temperature of the pan
is 80°F. Use Newton's Law of Cooling to find the pan's temperature after 15 minutes.
After 15 minutes the pan will have a temperature of °F.
(Round to the nearest integer.)
After 15 minutes the pan will have a temperature of 36°F
How to determine the temperature of the pan after 15 minutes?
Newton's Law of Cooling, if a body with temperature T₁ is placed in surroundings with temperature To, different from that of T₁, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = T₀ + (T₁-T₀)e^(kt)
Given: T₁ = 120°F, T₀ = 0°F. After 5 minutes, T(t) = 80°F
T(t) = T₀ + (T₁-T₀)e^(kt)
80 = 0 + (120-0)e^(5k)
80 = 120e^5k
e^5k = 80/120
e^5k = 2/3
5k = ln(2/3)
k = ln(2/3) / 5
k = -0.0811
The temperature of the pan after 15 minutes will be:
T(t) = T₀ + (T₁-T₀)e^(kt)
T(15) = 0 + (120-0)e^(-0.0811×15)
T(15) = 120e^(-0.0811×15)
T(15) = 36°F

PLEASE MARK AS BRAINLIESTRound each fraction to 0,1/2, or 1…… 7/12 5/6 2/11 4/9
Answer:
1/2, 1, 0, 1/2
Step-by-step explanation:
We can solve this by rounding each fraction to either 0, 1/2, or 1.
The first fraction, 7/12, is pretty close to 6/12, which is 1/2 of 12.
So we can round this to 1/2.
The second fraction, 5/6, is closer to 6/6 (1) than 3/6 (1/2).
So we can round this to 1.
The third fraction, 2/11 is closer to 0 than 5.5/11 (1/2).
We can round this to 0.
4/9 is closer to 4.5/9 (1/2) than 0.
We can round this to 1/2.
Therefore, when we round all of these fractions, we are left with 1/2, 1, 0, 1/2.

Rodrigo pays $165.40 per month on his car loan.
How much does he pay on his loan in 1 year?
Answer:

Step-by-step explanation:
165.40 times 12 equals 1984.80
Answer:
He pays $1984.80 on his loan in one year.
Step-by-step explanation:
If he pays 165.40 per month, and there are 12 months in one year, then we must multiply the values together.
165.4*12 = 1984.8
He pays $1984.80 on his loan in one year.

An initial sample of 171 g of a radioactive substance decays according to the function
A(t) = 171e ^ - 0.04(t) where t is given in years?
a) How many grams of the substance will remain after 59 years? Round your answer to the nearest decimal place.
b) What is the half-life of the substance? Round answer to the one decimal place.
There will be 0.48 grams will be left in the sample after 59 years.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Since we have given that initial sample of 171 g of a radioactive substance decays according to the function
[tex]A(t) = 171e ^ {- 0.04(t) }[/tex]where t is given in years
Here, Initial amount of radioactive substance = 171 grams
We need to find the amount of substance that will be left in the sample after 59 years.
So, t = 59 years
So, it becomes,
[tex]A(t) = 171e ^ {- 0.04(59) }\\\\A(t) = 0.48[/tex]
Hence, there will be 0.48 grams will be left in the sample after 59 years.

How many times as great is the value of 1.5 than the value of 0.15? Please Explain.
Answer:
Step-by-step explanation:
1.5/0.15=10
1.5 is 10 times greater than 0.15
The solution is 10
The number of times the number 1.5 is greater than the number 0.15 is 10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented A
Now , the value of A is
Let the first number be P = 1.5
Let the second number be Q = 0.15
Now , the number of times the number P is greater than Q is given by the equation
A = P / Q
Substituting the values in the equation , we get
A = 1.5 / 0.15
On simplifying the equation , we get
A = 10
Therefore , the value of A is 10

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of rides = m + 5
Number of games = m
Now,
Each game costs $1.50 and each ride costs $5. Isaac spent $44.50 altogether at the carnival.
This means,
1.50m + 5(m + 5) = 44.50
1.50m + 5m + 25 = 44.50
6.50m = 44.50 - 25
m = 19.5/6.50
m = 3
Now,
The number of games = 3.
The number of rides.
= m + 5
= 3 + 5
= 8

Find the size of angle x.
Give your answer correct to 1 decimal place.
Answer:
x° ≈ 25.5°
Step-by-step explanation:
The relationship between the two given sides and angle x are Opposite and Adjacent. So we'll use tan(x) = 10/21 to start.
Take the Inverse tan (tan⁻¹) to find x: x = tan⁻¹(10/21) ==> calculator
Answer:
x = 25.5°
Step-by-step explanation:
First find the hypotenuse of the right triangle given by the formula
[tex]c = \sqrt{a^{2} + b^{2}}[/tex]
where c is the hypotenuse and a, b the two sides
Let's call the vertical leg as a and the horizontal leg as b
Then we have a = 10, b = 21
So
[tex]c = \sqrt{10^{2} + 21^{2}}\\\\c = \sqrt{100 + 441}\\\\c = \sqrt{541}\\\\c = 23.2594\\\\\\[/tex]
By the law of sines, the ratios of the sides of a triangle to the sine of the angles opposite must be the same. The hypotenuse is opposite the 90° angle. and the side of length 10 is opposite angle x
So
[tex]\dfrac{23.2594}{\sin 90} = \dfrac{10}{\sin x}[/tex]
But sin 90 = 1. So the above equation reduces to
[tex]2.2594 = \dfrac{10}{\sin x}\\\\\\\implies \sin x = \dfrac{10}{23.2594}\\\\\implies \sin x = 0.43\\\\\\\\x = sin ^{-1}(0.43) = 25.4675\\\\[/tex]
Rounded to 1 decimal place
x = 25.5°
