The committee is planning a party and 150 guests are expected. Each table seats 12 people. How many tables will be needed to seat all 150 guests?
Answer:
You will need about 13 tables.
Step-by-step explanation:
I divided the number of guests by 12 and got 12.5 however you can't have half of a table so I rounded up and got 13.
AC = 5x - 8 and CD = 16 - 3x
x=
AD=
Answer:
Step-by-step explanation:
5x - 8 = 16 -3x
8x - 8 = 16
8x = 24
x = 3
AC= 5(3) - 8 = 15 - 8 = 7
CD= 16 - 3(3) = 16 -9 = 7
7 + 7 = 14 = AD
The value of x and AD such that C is the midpoint of AD is 3 and 14 respectively.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given the line segment AD with mid-point C
So,
AC = CD
5x - 8 = 16 - 3x
8x = 16 + 8
x = 3
So,
AD = 5x - 8 + 16- 3x
AD = 2x + 8
AD = 2(3) + 8 = 14
Hence "The value of x and AD such that C is the midpoint of AD is 3 and 14 respectively".

if the bacteria population is doubling every hour, can you estimate the bacteria population at the time of 10 hours?
Answer:
Bacterial population at the time of 10 hours = 1040000
Step-by-step explanation:
Let the function that defines the bacterial population after 'x' hours is,
p(x) = a(b)ˣ
Where a = Initial population
And 'x' = Duration or time
Since bacterial population is getting doubled every hour,
2a = a(b)¹
b = 2
Therefore, function will be,
p(x) = a(2)ˣ
From the graph attached,
Point (5, 32500) lies on the graph of the function.
32500 = a(2)⁵
a = [tex]\frac{32500}{32}=1015.625[/tex]
Therefore, the function will be,
p(x) = 1015.625(2)ˣ
For x = 10 hours,
p(10) = 1015.625(2)¹⁰
= 1040000 bacteria

NEED HELP ASAP ALGEBRA 2
Answer:
15
Step-by-step explanation:
Use the pythagorean theorem.
A² + B² = C²
In this case, A = 8, B is unknown, and C = 17. B is the side that we want to calculate.
8² + B² = 17²
64 + B² = 289
B² = 225
B = √225 = 15
If the data in a scatter plot form a nearly perfect circle, the Pearson correlation would be approximately ____.
Answer:
zero
Step-by-step explanation:
Pearson correlation coefficient represented by r is calculated by dividing the covariance by the standard deviation of one variable(x) multiply by the standard deviation of the other variable(y).
A scatter plot diagram is a graphical display of data that in which these two variables are observed simultaneously.
A positive correlation is said to have a positive slope which means that the two variable x and y increases in x as there is increase in y.
On the other hand , when there is an increase in x and a decrease in y, the correlation between x and y is said to be negative and the corresponding regression line has a negative slope.
Occasionally, there may be no apparent association between x and y. In that wise, the data in the scatter plot diagram usually form a nearly perfect circle and are said to have a zero correlation.

Answer:
no
Step-by-step explanation:
The circumference of a table is ...
C = πd = π(180 cm) ≈ 565.5 cm
At 70 cm/guest, a table will accommodate ...
565.5 cm/(70 cm/guest) = 8.08 guests
At 8 guests per table, the available 18 tables will accommodate ...
(18 tables)(8 guests/table) = 144 guests
There is not enough space at 18 tables for 145 guests.
Answer:
No, it's not.
Step-by-step explanation:
First, find the circumference of the table:
C = 2πr
= 2 × 22/7 × 180/2
NOTE: Diameter/2 is equal to the radius because half of Diameter is a radius.
= 44/7 × 90
= 3,969/7
= 565.71 approximately 566cm²
Next, find how many guests can occupy a table:
566/70 = 8.08 approximately 8 guests.
Now, how many guests will be in 18 tables?
18 × 8 = 144 guests, but we need 145 guests, so it is not enough.

A particle travels 16.5 km in 30 minutes. What will be the speed of the particle in km / h ?
s=d/t
Step-by-step explanation:
s=16.5/0.5
s=33
33 km/h since 30 min is half an hour
Answer:
[tex] \boxed{ \huge{ \boxed{ \sf{ \bold{33 \: km/h}}}}}[/tex]Step-by-step explanation:
Distance ( d ) = 16.5 km
Time ( t ) = 30 minutes
( To convert minutes to hour , divide the minutes by 60)
Time ( t ) = [tex] \sf{ \frac{30}{60} }[/tex] = [tex] \sf{0.5}[/tex] hours
Now, let's find the speed

Ariel completes the square for the function y=x^2-16x+17. What is the function of the parabola?
Answer:
y = (x - 8)² - 47
Step-by-step explanation:
x² - 16x + 17 = 0
x² - 16x = -17
(-16) / 2 = -8
-8² = 64
x² - 16x + 64 = -17 + 64
(x - 8)² = 47
y = (x - 8)² - 47

Answer:
422 cm²
Step-by-step explanation:
Surface area of the composite figure = (surface area of the upper cuboid + surface area of lower cuboid) - 2(base area of the lower cuboid)
Surface area of composite figure = [tex] (2(lw + lh + hw)) + (2(lw + lh + hw)) - 2(l*w) [/tex]
Upper cuboid has the following dimensions:
[tex] l = 4, w = 3, h = 8 [/tex]
Lower cuboid has the following dimensions:
[tex] l = 10, w = 7, h = 5 [/tex]
Plug these values into the formula
Surface area of composite figure
[tex] = (2(4*3 + 4*8 + 8*3)) + (2(10*7 + 10*5 + 5*7)) - 2(4*3) [/tex]
[tex] = (2(12 + 32 + 24)) + (2(70 + 50 + 35)) - 2(12) [/tex]

Suppose that we have a given property (or a pattern if we are working with a series of numbers):
Now, if that property is true, for example, for the numbers 1, 2, 3... etc. Then we can suppose that the property is also true for an unknown number N.
Now, if using the hypothesis that the property is true for N, we can prove that the property is also true for N + 1, then we actually proved that the property is true for all the set.
We actually can use any set, not only the natural numbers.
For example, we can use the set of the even numbers {2, 4, 6, 8....}, suppose that the property is true for a random number N, that is even, and then see if using that hypothesis we can prove that the property is also true for the next number in the set; N + 2.
