512 c2 so A sorry if im wrong
Answer:
384
Step-by-step explanation:
So there are 6 faces in a cube so first you need to know how big is one face then just multiply by 6 for all 6 faces. so 8*8 = 64. that means 64 is the area of one face.
then multiply that by 6 to get the total surface area.
there it is your answer 384 the 3rd option there
Write the equation of the line that passes through the points (4, -8) and (-8, 1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y = -3/4x -5
Step-by-step explanation:
(4, -8) and (-8, 1)
m = (y2-y1)/(x2-x1)
m= (1+8)/(-8-4)
m = (9)/(-12)
m = -3/4
y - y1 = m(x-x1)
y + 8 = -3/4(x -4)
y + 8 = -3/4x + 3
y = -3/4x -5
Answer:
y = -3/4x - 5

a wedding planner accounts for 8 chairs at every round table. how many tables will be needed to seat 175 people?
Answer:
21.875
Step-by-step explanation:
you do 175 divided by 8
The required number of tables to seat 175 people are 22.
What is division?Division is defined as the splitting of a large group into smaller groups such that every group will have an equal number of items.
it is given that,
Number of chairs for 1 table = 8
Number of people to seat = 175
Therefore chairs = 175
Since 8 chairs are required at every round table
Therefore,
Number of tables to seat 175 people = Number of people to seat/Number of chairs for 1 table
⇒ Number of tables to seat 175 people = 175/8
⇒ Number of tables to seat 175 people = 21.87 ≈ 22 tables
Thus, the required number of tables to seat 175 people are 22.

Step-by-step explanation:
radius = 4
area of circle = pi * r * r
16 pi is area = 50.2655 units^2 (to 4dp)
Answer:
50.24
Step-by-step explanation:
Area of the circle is [tex]\pi r^{2}[/tex]. If the diameter is 8, then we know that the radius is 4, because the radius is half of the diameter. Then solve. 4 squared is 16, then multiply by 3.14 in place of pi and you will get 50.24. So yes, you are correct, it is 50.24.

Determine the coordinates of the y-intercept of 3x − 4y = 24.
Answer:
(0, -6)
Step-by-step explanation:
At the y-intercept, the x-coordinate equals zero.
3x - 4y = 24
3(0) - 4y = 24
-4y = 24
y = -6
Answer: (0, -6)
The nth term of the sequence is n^2 + 20
How many terms in the sequence are less than 50
plss help!!
Answer: 5 terms.
Step-by-step explanation:
We know that the n-th term of a sequence is:
Aₙ = n² + 20
Where n can be any natural number, then n ∈ {1, 2, 3, ...}
We want to find how many terms are smaller than 50.
Then we could find the first value of n such that Aₙ is equal or larger than 50.
Then we can solve:
Aₙ = n² + 20 = 50
then:
n² = 50 - 20 = 30
n = √30 = 5.48
This is not a natural number, so we need to round to the next one that is n = 6
This means that the first natural number n such that Aₙ is equal or larger than 50 is n = 6, then for the values:
n = 1, 2, 3, 4, 5
Aₙ is smaller than 50
This means that there are 5 terms of the sequence that are smaller than 50.

How do you find the base in the Pythagorean theorem, c=18, a=9, what is b?
Answer:
b = 15.59
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + b^2 = 18^2
81 + b^2 = 324
-81 -81
b^2 = 243
b = 15.59
Pythagorean Theorem -
[tex]a^{2} + b^{2} = c^{2} [/tex]
1 - Input the values!
[tex] 9^{2} + x^{2} = 18^{2} [/tex]
2. Find the exponents!
[tex]81 + x^{2} = 324[/tex]
3. Multi step Equations!
[tex]81 - 81 = 0 \\ 324 - 81 = 243[/tex]
4. Use square roots to find x!
[tex]x = \sqrt{243}[/tex]

Find the length side
Answer:
PR = 6.93 units
PQ = 13.86 units
Step-by-step explanation:
From ΔPQR,
m∠Q = 30°
QR = 12
By applying tangent rule for the given angle in the triangle,
tan(30°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(30°) = [tex]\frac{PR}{QR}[/tex]
[tex]\frac{1}{\sqrt{3}}=\frac{PR}{12}[/tex]
PR = [tex]\frac{12}{\sqrt{3} }[/tex]
PR = 4√3 ≈ 6.93
Now we apply cosine rule,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{QR}{PQ}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{12}{PQ}[/tex]
PQ = [tex]\frac{24}{\sqrt{3} }[/tex]
PQ = 8√3 ≈ 13.86
The distance y (in miles) that Train A travels in x hours is represented by the equation y=68x . The graph shows the distance that Train B travels. (0, 0) and (1, 64).
Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.
find the slope of the line graphed below.
