Answer:
Table 2
Step-by-step explanation:
We can solve this by dividing the number of pizzas at each table by the number of kids at each table. This will tell us how much pizza each kid is able to eat:
Table 1:
2 pizzas/5 kids = 2/5 pizzas per kid = 0.4 pizzas per kid
Table 2:
3 pizzas/7 kids = 3/7 pizzas per kid = 0.429 pizzas per kid
Table 3:
5 pizzas/12 kids = 5/12 pizzas per kid = 0.417 pizzas per kid
The kids at table 2 are able to eat slightly more pizza than the kids at the other tables.

Step-by-step explanation:
Find the value of x. Then find the measure of each labeled angle
Answer:
x = 12
9x = 108º
6x = 72º
Step-by-step explanation:
The angles sum to 180º
9x + 6x = 180
15x = 180
x = 12
9x = 9 * 12 = 108
6x = 6 * 12 = 72
In the given parallelogram, we can see that 9x° & 6x° are adjacent angles. 2 adjacent angles in a parallelogram sum up to 180°. So,
9x° + 6x° = 180°
15x° = 180°
x = 180/15
x = 12
Now,
6x° = 6 × 12 = 72°
9x° = 9 × 12 = 108°.
=》The value of 'x' is 12 & the measure of each labelled angle is 72° & 108°.

y=-4/3x+1 is the equation of the line perpendicular to 3/4x+5 and goes through the point 3,-3
Step-by-step explanation:
Note that the co-efficient before x is the slope, which i will call m, and a perpendicular line has a slope of -1/m.
-1/m=-4/3
so
y=-4/3x+z,
plug in 3 for x, and -3 for y to get z=1
y=-4/3x+1 is the equation

If you start with 85 milligrams of Chromium 51, used to track red blood cells, which
has a half-life of 27.7 days.
How long will it take for 90% of the material to decay?
About 92 days are taken for 90 % of the material to decay.
The mass of radioisotopes ([tex]m[/tex]), measured in milligrams, decreases exponentially in time ([tex]t[/tex]), measured in days. The model that represents such decrease is described below:
[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)
Where:
[tex]m_{o}[/tex] - Initial mass, in milligrams.[tex]m(t)[/tex] - Current mass, in milligrams.[tex]\tau[/tex] - Time constant, in days.In addition, the time constant is defined in terms of half-life ([tex]t_{1/2}[/tex]), in days:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
If we know that [tex]m_{o} = 85\,mg[/tex], [tex]t_{1/2} = 27.7\,d[/tex] and [tex]m(t) = 8.5\,mg[/tex], then the time required for decaying is:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex]
[tex]\tau = \frac{27.7\,d}{\ln 2}[/tex]
[tex]\tau \approx 39.963\,d[/tex]
[tex]t = -\tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]
[tex]t = -(39.963\,d)\cdot \ln \frac{8.5\,mg}{85\,mg}[/tex]
[tex]t\approx 92.018\,d[/tex]
About 92 days are taken for 90 % of the material to decay.

The basketball team and volley ball team are having a competition to see which team can raise the most money for a local charity.
The basketball team is selling raffle tickets for 4.50 each and has already raised $275
The volleyball team is selling raffle tickets $2.50 each and has already raised $500
write an equation to present total (T) that each team has raised after selling (x) number of raffle tickets
Basketball Team: ____________
Volleyball Team: ____________
write an equation that would represent when the basketball team would have more money than the volleyball team.
How many tickets would the basketball team need to sale to have more money than the volleyball team?
Basketball Team Equation: _________
Volleyball Team Equation: _________
Basketball answer:_____
Volleyball answer:_____
Answer:
Step-by-step explanation:
write an equation to present total (T) that each team has raised after selling (x) number of raffle tickets
Basketball Team: T(B) = 4.50x(B)
Volleyball Team: T(V) = 2.50x(V)
The problem staes use x for the number of tickets, but I've noted these numbers as a function of basketball, x(B), and volleyball, x(V).
We know the amounts each team has raised, sio we can calculate the number of tickets:
Basketball
$275 = $4.50x(B)
x(B) = 61.11 [There can't be 0.11 ticket, so round down to 61 and declay an error in making change]: 61 tickets from the Baseball team
$500 = $2.50x(V)
x(V) = 200 tickets from the Volleyball team
---
"write an equation that would represent when the basketball team would have more money than the volleyball team."
We want the ratio of T(B) to T(V) to be greater than 1 [the total basketball sales are greater than the total Volleyball sales.]
T(B)/T(V) = ($4.50x(B))/($2.50x(V))
1 <= ($4.50/$2.50)*(x(B)/x(V))
1 <= 1.8(x(B)/x(V))
x(V) <= 1.8*(x(B))
The baseball team needs to sell 1.8 times the number of tickets sold by the baseball team.
----
The basketball team is jealous and wants to know how many more tickets they need to sell to catch up with the volleyballers.
To reach $500:
$500 = $4.50*x(B)
x(B) = 111.11 (Another rounding problem, but we don't need to worry. It wants to kniow "how many MORE."
(111.11 - 61.11) = 50 more tickets to reach the same $500 the Volleyball team has collected.

Answer:
They are the same because they have the same slope, 2. and they are different because they different y-intercepts, 0 and 8.
Step-by-step explanation:
Your equations y=mx+b
m is your slope, both 2 and
b is your y-intercept, 0 for your first one because it doesn't have any, and 8 for your second one.
Solve the system you found in Part D. Did you use elimination or substitution? What was the entry fee, and how much did each ticket cost?
After Gwen, Tristan, and Keith finish exercising, they go to the fair. At the fair, they each pay the entry fee and also buy tickets they can use for food or rides. Gwen pays the entry fee and buys 10 tickets. It costs her a total of $30. Tristan pays the entry fee and buys 15 tickets. It costs him a total of $40. Keith pays the entry fee and buys 10 tickets. It costs him a total of $30. In this task, you will create a system of equations and find the cost of each ticket. Let x represent the entry fee and y represent the cost of each ticket in dollars.
Answer:
Let x represents the entry fees
y represent the cost of each ticket
Gwen equation
x + 10y = 30 ... (i)
Tristan equation
x + 15y = 40 ...... (ii)
Keith equation
x + 10y = 30 .......... (iii)
By solving eq. (ii) and (iii), we get
x = 10
y = 2
Hence entry fees = $10
cost of each ticket = $2

x = 8√2
Step-by-step explanation:
use the pythagorean theorem with the 2 sides being the same
16^2 = x^2 + x^2
256 = 2x^2
Divide both sides by 2
128 = x^2
Take the square root of both sides
x = √128
x = √(64 * 2)
x = 8√2
Answer:
x= [tex]8\sqrt{2}[/tex] or 11.31
Step-by-step explanation:
You know that the shape is a square that is divided making 2 triangles. They are examples of 45-45-90 degree triangles. So with this information, you know that both lengths of the triangles are equal, with a hypotenuse of 16.
Side C= 16
Side A= Side B
45-45-90 Formula
Side C= [tex]a\sqrt{2}[/tex]
16= [tex]a\sqrt{2}[/tex]
[tex](16= a\sqrt{2})^{2}[/tex]
256=[tex]2a^{2}[/tex]
128=[tex]a^{2}[/tex]

One week, London earned $313.50 at her job when she worked for 15 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $647.90?
Answer:
31 hours
Step-by-step explanation:
First you take 313.50 divide that by 15 get 20.9 per hour
Then you take 647.90 and divide that by 20.9
