Answer:
Total cost= 99 + 2.97x
Step-by-step explanation:
Giving the following information:
Fixed cost= $99
Variable cost= 3% per person
First, we need to calculate the 3% of 99:
Unitary variable cost= 99*0.03= $2.97
Now, we establish the total cost structure:
Total cost= 99 + 2.97x
x= number of people in attendance
Finally, suppose 200 people attend the party:
Total cost= 99 + 2.97*200
Total cost= $693
Answer:
99+3x
Step-by-step explanation:
Given;
Party cost $99
$3 per person who attends
To Find;
Which expression can Jess use to figure out the total amount of money she owes at the end of the party?
Solve;
Since, we don't know the total amount of money she owes at the end of the party. Total amount of money she owes at the end of the party = x
Thus, Party Costs ($99) plus per person who attends($3) and Total amount of money she owes at end of party (x)
As well as,
[A] 33x, [B] 33 + x, and [D] 99x+3 didn't clearly or completely shows the party's situation. Hence, the Best Answer is [C] 99+3x

Name two pairs of supplement angles in the diagram
Answer:
Two angles whose sum is 90° (that is, one right angle) are called complementary angles and one is called the complement of the other.
Here, ∠AOB = 40° and ∠BOC = 50°
Therefore, ∠AOB + ∠BOC = 90°
Here, ∠AOB and ∠BOC are called complementary angles.
∠AOB is complement of ∠BOC and ∠BOC is complement of ∠AOB.

x^2-8x + 10 = 0
First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation. Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
Answer:
[tex]x =4 + \sqrt{6}, \: \: 4 - \sqrt{6}[/tex]
Step-by-step explanation:
[tex]x^2-8x + 10 = 0 \\ \\ \implies \: x^2-2(x)(4) + 10 = 0\\ \\ \implies \: x^2-2(x)(4) + {(4)}^{2} - {(4)}^{2} + 10 = 0\\ \\ \implies \: x^2-2(x)(4) + {(4)}^{2} - 16 + 10 = 0\\ \\ \implies \: (x - 4)^2 - 6= 0\\ \\ \implies \: (x - 4)^2 = 6\\ \\ \implies \: x - 4 = \pm \sqrt{6} \\ \\ \implies \: x = 4 \pm \sqrt{6} \\ \\ \implies \: x =4 + \sqrt{6}, \: \: x =4 - \sqrt{6}[/tex]

x^2=40
Will give brainliest if correct and explained!!
Answer:
x= 6.324555320
Step-by-step explanation:
X^2=40
1. Square root both sides
2. You should be left with x=6.32....
Solution: √40 = x
So basically, you have to find x, which is raised to the power of two. To find that, we'll have to square root 40 because square rooting a number is the opposite of squaring a number
So 40 squared = 6.32455532034
A really long number...
Now, let's check our answer
6.32455532034^2 = 40
So therefore, x = 6.32455532034
Hope this helped!!

anyone know how to do exponential functions?
Answer:
[tex]y=3^x[/tex]
Step-by-step explanation:
exponential function : y = a(b)^x
where a = y intercept and b = factor ( number you are multiplying by )
according the the graph the y intercept is a 1 so a = 1
we now have y = 1(b)^x
to find the factor you plug in one of the ordered pairs into y = 1(b)^x
the ordered pair you use will not effect the outcome, i have chose (2,9)
y = 1(b)^x
(x,y) = (2,9) so x = 2 and y = 9
9 = 1(b)^2
divide both sides by 1
9 = (b)^2
take the square root of both sides
3 = b
the final equation is y = 1(3)^x or just y = 3^x

A student drops a rock over the edge of the well and hears it splash into water after 3 seconds. Write a function in the form h(t) = − 16t2 + v0 t + h0 to determine the height of the rock above the bottom of the well t seconds after the student drops the rock. What is the distance from the surface of the water to the bottom of the well?
Answer:
h(t) = -16t² + 200
distance = 56 ft
Step-by-step explanation:
First of all, we know that the initial velocity (v0) of the rock is 0 ft/s because the rock was dropped. We also know that the initial height of the rock is 200 ft because it was dropped at the top of the well which is 200 ft high. Plugging this information into our quadratic function we get h(t) = -16t² + 200.
Now we need to find the distance from the surface of the water to the bottom of the well. This distance is equal to the height of the rock at time equals 3 seconds. Therefore, all we need to do is find h(3) = -16(3)² + 200 = 56 ft.

what is the equstion of s line with a y-intercept of -5 and a slope of 8
Answer:
y = 8x - 5
Step-by-step explanation:
Given:
Slope: 8Y-intercept: -5To find:
Equation.How to find:
The slope is always known as "constant of variation" or "rate of change", but it's basically the increase of both y and x axes in simple terms. The decrease or increase in two points together and then found with the formula of rise/run (increase and decrease) (horizontal line/vertical line).
The y-intercept is always on the y-axis and is the beginning of what is learned in pre-algebra as a "story" which helps students practice finding the slope which again, is the change with "per" or "each".
Make sure to use the formula:
y = mx + b
Now we insert.
y = 8x <---------- slope
y = 8x - 5 <------ y-intercept and completed slope-intercept equation.
The reason it has a negative is because it started out as a negative y-intercept and is increasing by 8 through ordered pairs.
Answer:
y = 8x - 5
Step-by-step explanation:
because if its has a slope of 8 then m is 8
if the y intercept is -5 the b is -5
y = mx + b
y = 8x -5

At a restaurant, you order an appetizer for $5.25, a meal for $12.75, and a drink for $2.99. If the sales tax is 9%, what is the total of your bill including sales tax?
Answer:
$22.88
Step-by-step explanation:
The total bill is the subtotal plus tax. The tax is computed by multiplying the tax rate by the subtotal, which is the total of all items being billed.
subtotal = $5.25 +12.75 +2.99 = 20.99
tax = $20.99 × 0.09 = $1.89
The total bill is ...
subtotal + tax = $20.99 +1.89 = $22.88

Can someone slove this equation system please????
Answer:
Step-by-step explanation:
Multiply the top equation by 3.
3*(x - y)/3 = 0.5 * 3
(x - y) = 1.5
There is no single solution that satisfies this system. There infinitely many values for x and y that will work. The only restriction is that x - y = 1,5
So if you make y = 3
x - 3 = 1.5 Add 3 to both results
x - 3 + 3 = 1.5 + 3 Combine
x = 4.5
Infinitely many solutions exist.
