Step-by-step explanation:
The holcombe family went out to dinner the meal cost 54.65 the sales tax is 8 peecent the tip was 18 percent of the meal and tax there are 5 people in the holcomebe family what was the cost per person for the meal including sales tax and tip
Answer:
13.93
Step-by-step explanation:
Meal = 54.65
Sales tax = 8%
= 8/100 * 54.65 + 54.65
= 0.08 * 54.65 + 54.65
= 4.372 + 54.65
= 59.022
Tip = 18% of the meal and tax
= 18/100 * 59.022 + 59.022
= 0.18 * 59.022 + 59.022
= 10.62396 + 59.022
= 69.64596
Total people in the holcomebe family = 5
Cost of meal per person =
69.64596 / 5
= 13.929192
Approximately 13.93

1. When you move the decimal point, how can you know whether you are
increasing or decreasing the number?
Answer:
If u divide a number the number will decrease
if u multiply the decimal number it will increase.
when multiplying u move the decimal point to the right
if u r dividing u move the decimal point left
how much u move depends on the number of zeros from the number u are dividing or multiplying

why are there two values of theta if tan theta = 0.4226
Answer:
[tex]22.91^\circ, 202.91^\circ[/tex]
Step-by-step explanation:
Given that:
[tex]tan\theta=0.4226[/tex]
To find:
The two values of [tex]\theta = ?[/tex]
Solution:
By given equation:
[tex]\theta = tan^{-1}(0.4226)[/tex]
[tex]\theta[/tex] can be equal to [tex]\approx 20.91^\circ[/tex]
Also, we know the property that, [tex]tan\theta[/tex] is positive in the 3rd quadrant.
and following is also true:
[tex]tan\theta = tan(180^\circ+\theta)[/tex]
Therefore, another value possible for [tex]\theta[/tex] can be:
[tex]\theta =180^\circ+22.91\\\Rightarrow \theta \approx 202.91^\circ[/tex]
Therefore, the answer is:
[tex]22.91^\circ, 202.91^\circ[/tex]
Help hurry need to turn in soon
Answer: x = [tex]\frac{-z - 7}{y}[/tex]
Step-by-step explanation:
Flip the equation
xy + z = −7
Add -z to both sides
xy + z + −z = − 7 + −z
xy = −z − 7
Divide both sides by y
[tex]\frac{xy}{y}[/tex] = [tex]\frac{-z - 7}{y}[/tex]
x = [tex]\frac{-z - 7}{y}[/tex]
x = [tex]\frac{-z - 7}{y}[/tex]

Answer:
y = 1/2x, 2:1y = 5x, 1:5y= 1.5x, 16:24y = 3x, 1:3Step-by-step explanation:
Number replaces with each corresponding value.
The number on the left is the x, and the number on the right of the colon is y.
Simply replace x and if you get the y, it is a match.
y = 1/2(2) = 1
y = 5(1) = 5
y = 1.5(16) = 16
y = 3(1) = 3
And electronics store chain sells headphones The company is about to introduce a new headphones model that is expected to sell very well across its various stores. The projected revenue and cost functions for the headphones are R(x)=-0.25x+25x and c(x)= -17+90. What is the profit function
Answer:
[tex]P(x) = -0.25x^2 + 42x - 90[/tex]
Step-by-step explanation:
Given
[tex]C(x) = -17x + 90[/tex]
[tex]R(x) =- 0.25x^2 + 25x[/tex]
Required
Determine the profit function.
Profit function is calculated as thus:
[tex]P(x) = R(x) - C(x)[/tex]
So, we have:
[tex]P(x) = -0.25x^2 + 25x -(-17x + 90)[/tex]
[tex]P(x) = -0.25x^2 + 25x + 17x - 90[/tex]
[tex]P(x) = -0.25x^2 + 42x - 90[/tex]
Write a compound inequality that represents the Fahrenheit temperatures between 50 degrees Celsius and 70 degrees Celsius.
Answer:
122 ≤ F ≤ 158
Step-by-step explanation:
First we convert the Celsius temperature to Fahrenheit
Mathematically, the formula to use is as follows;
F = 9/5C + 32
So 50 will be;
F = 9/5(50) + 32 = 90 + 32 = 122
70 will be
F = 9/5(70) + 32 = 126 + 32 = 158
So the inequality will be;
122 ≤ F ≤ 158
-40-2(3m+1/2)=7m-2 what does m equal
Answer: [tex]m[/tex] = −3
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
Step 1: Expand.
−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2
Step 2: Simplify −40 − 6[tex]m[/tex] − 1 to −6[tex]m[/tex] − 41.
−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2
Step 3: Add 6[tex]m[/tex] to both sides.
−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]
Step 4: Simplify 7[tex]m[/tex] − 2 + 6[tex]m[/tex] to 13[tex]m[/tex] − 2.
−41 = 13[tex]m[/tex] − 2
Step 5: Add 2 to both sides
−41 + 2 = 13[tex]m[/tex]
Step 6: Simplify −41 + 2 to −39.
−39 = 13[tex]m[/tex]
Step 7: Divide both sides by 13.
−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]
Step 8: Simplify [tex]\frac{39}{13}[/tex] to 3.
−3 = m
Step 9: Switch sides.
[tex]m[/tex] = −3

Find the value of w. (5w+3)
The solution is: in the expression (5w+3) the value of w is: w = -3/5.
Here, we have,
given that,
the expression is: (5w+3)
now, we have to find the value of w
so, we get,
we can find the value of w by making it equal to 0:
5w+3 = 0
<- subtract 3 from both sides
5w = -3
<- divide 5 from both sides
5w/5 = -3/5
so, we have,
w = -3/5 is the final answer.
Hence, The solution is: in the expression (5w+3) the value of w is: w = -3/5.

The supplementary angle of 57° is
Answer:
123°
Step-by-step explanation:
A supplementary is an angle where two angles add up to be 180°.We can subtract to find its supplement.
180 - 57 = 123°
Best of Luck!
Answer:
123°
Step-by-step explanation:
The supplementary angle is the other angle that makes both angles a linear pair.
So you would do 180° - 57° to solve your answer, which equals 123°
Hope this helps!
which equations have exactly one y-value for any given x-value? select all that apply
A.y=-x
B.x=4
C.y=x^2
D.y=x^3
Answer:x=4
Step-by-step explanation:
The equations y = -x,y = x², and y = x³ have one y-values for a given x-value thus options (A) ,(C) and (D) will be correct.
What is the equation?There are many different ways to define an equation.
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
In the first option y = -x
The value of y will be negative of x thus it will be single for every single x.
In the third option x = x² here for every x there will be a single y thus it will be single for every single x.
In option fourth option y = x³ here for x, y will be one thus it will be single for every single x.
In option (B) x = 4 here y is changing for x = 4 thus here y will not be one.
Hence "The equations y = -x,y = x², and y = x³ have one y-values for a given x-value".
