Work out the volume of the prism height of 12 4 and five
The calculated volume of the prism is 702 cubic cm
Finding the volume of the prismFrom the question, we have the following parameters that can be used in our computation
The trapezoidal prism (see attachment)
The formula of the volume of a trapezoidal prism is
Volume = Base area * Height
Where we have
Base area = 1/2 * (8 + 10) * 6
Evaluate the sum of 8 and 10
Base area = 1/2 * 18 * 6
Evaluate the products of 1/2, 18 and 6
Base area = 54
Also, we have
Height = 13
So, the volume is calculated as
volume = 13 * 54
Evaluate
volume = 702
Hence, the volume of the prism is 702 cubic cm

Step-by-step explanation:
Hi there! I need help understanding the following graph question. y=2 * 1/2. the number 1/2 has what looks like a letter exponent above the one. Please zoom attached picture. The answer is A not the circled answer. Does it apply to the formula y=mx+b?
Given the following exponential equation:
\(y=2\cdot(\frac{1}{2})^x\)For x = 0, we have:
\(y=2\cdot(\frac{1}{2})^0=2\cdot1=2\)Then, the y-intercept must be y = 2. Now, for x = -2:
\(y=2\cdot(\frac{1}{2}){}^{-2}=2\cdot(2)^2=2\cdot4=8\)Looking at D, we see that the y-intercept is 4, so this graph does not correspond to the equation. Looking at B and C, we see that y ≠ 8 for x = -2, so we discard them.
For A:
We see that y = 8 for x = -2, and the y-intercept is 2. Then, this is the corresponding graph of the equation.

Answer:
x = 16
Step-by-step explanation:
Step 1: We know DF - DE = EF
9x - 39 - 47 = EF
Step 2: Simplify
9x - 86 = EF
Step 3: Set the equation equal to 3x + 10
9x - 86 = 3x + 10
6x = 96
x = 16
Therefore x is equal to 16
Answer:
58
Step-by-step explanation:
DE + EF = DF
47+ 3x+10 = 9x-39
Combine like terms
57 +3x = 9x-39
Subtract 3x from each side
57+3x-3x = 9x-3x-39
57 = 6x-39
Add 39 to each side
57+39 = 6x-39+39
96 = 6x
Divide by 6
96/6 = 6x/6
16 =x
We want the length of EF
EF = 3x+10
= 3*16 +10
= 48+10

At colleges in Jacksonville, do tennis coaches generally get paid more than football coaches?
It is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a Wide range of factors
As an AI language model, I do not have access to up-to-date information about salaries of coaches in Jacksonville. However, in general, the salaries of coaches vary widely depending on a number of factors, such as the type of sport, the level of competition, the location, the success of the team, and the budget of the institution.
In terms of tennis and football, football is generally considered to be a more popular and high-profile sport than tennis in the United States, which could result in higher salaries for football coaches at the collegiate level. Football also typically generates more revenue and has larger budgets for athletic programs, which could also influence the salaries of coaches.
However, there are also factors that could affect the salaries of tennis coaches. For example, if a tennis program has a particularly successful season or has produced successful players, the coach may negotiate a higher salary. Additionally, some colleges may place a greater emphasis on tennis or have larger budgets for tennis programs, which could also impact the salaries of coaches.
Overall, it is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a wide range of factors. It is also important to note that salaries can vary widely between individual institutions, even within the same sport, and that negotiations between coaches and their institutions can play a significant role in determining salaries.

Jon Deposits $7,050 into an account paying 5% annual interest compounded quarterly and Sara deposits $4,867 into an account paying 10% annual interest compounded daily who will have more money after 1 year? How much more will that person have? Show and explain all work.
Juan will have more amount money after a year and with a difference of $2048.3.
What is compound interest?Compound interest is the interest you earn on interest.
For example if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
The total amount in compound interest is expressed as;
A = P( 1+r/n)^{nt}
where p is the principal, r is the rate and n is the interval at which its compounded.
For Jon
P = $7050, r = 5% = 0.05, n = 1/4 of 12 = 3
A = 7050( 1+0.05/3)^{3×1}
A = 7050( 1.017)³
A = 7050 × 1.052
A = $7416.6
Therefore the total amount for Juan after a year is $7416.6
For Sara,
P = $4867, r = 10% = 0.1 , t = 1.,.n = 365
A = 4867( 1+ 0.1/365) ^{365×1)
A = 4867( 1.00027)^365
A = 4867 × 1.103
A = $5368.3
therefore the total amount for Sara after a year is $5368.3
Therefore Juan will have more money after a year and with a difference of $2048.3

Please help!! I’ve been stuck on this for days!!! Finding the common difference and equation for the following arithmetic sequence! Thanks
The common difference is d = -4, since
-32 - (-28) = -4
-36 - (-32) = -4
-40 - (-36) = -4
and so on.
In the arithmetic sequence starting with \(a_1=-28\) and common difference -4, the next term is obtained by adding -4 to the previous one:
\(a_1 =-28\)
\(a_2 = a_1 + d = -28 - 4 = -32\)
\(a_3 = a_2 + d = a_1+2d = -28-4\times2 = -36\)
\(a_4 = a_3 + d = a_1+3d = -28-4\times3 = -40\)
and so on, up the n-th term
\(a_n = a_{n-1}+d = a_1+(n-1)d = \boxed{-28-4(n-1)}\)

Bethan,jack,Ruben collect marbles
Bethan has 4 more marbles than jack
Ruben has 1 less marble than Bethan
Altogether that have 97 marbles
How many marbles do they eatch have
In the word problem, Bethan has 34 marbles , Jack has 30 marbles and Ruben has 33 marbles.
What is equation?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
Here let us take Bethan's marbles as b , Jack's marble as j and Ruben's marbles as r.
Bethan has 4 more marbles than jack then,
=> b = j+4 -------> 1
Ruben has 1 less marble than Bethan then,
=> r = b-1 -------> 2
Put 1 into 2 then,
=> r = j+4-1
=> r = j+3 ----> 3
and they altogether have 97 marbles then
=> b + j + r = 97 ------> 4
Now put 1 and 3 equations into 4 equation then
=> j+4+j+j+3 = 97
=> 3j = 97-7
=> 3j = 90
=> j = 90/3 = 30
Now put j=30 into 1 then, b= j+4=30+4 = 34
Put j=30 into 3 then , r = j+3 = 30+3 =33.
Hence Bethan has 34 marbles , Jack has 30 marbles and Ruben has 33 marbles.

Answer:
x = 0
Step-by-step explanation:
The distributive property of multiplication states that a(b - c) = a(b) - a(c). We can apply that to the given equation.
3(2 - x) = 6
3(2) - 3(x) = 6 (Apply distributive property on LHS)
6 - 3x = 6 (Simplify LHS)
6 - 6 - 3x = 6 - 6 (Subtract 6 from both sides)
-3x = 0 (Simplify both sides)
\(\frac{-3x}{-3} =\frac{0}{-3}\) (Divide both sides by -3)
x = 0 (Simplify)

Standard deviation is the average distance away from the mean, thus B is correct
Starting at 300 feet away, a car drives towards you. IT then passes you by at a constant speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds is given by the equation d=|300-48t|. AT what times is the car 60 feet from you?
The car is 60 feet away from you after___seconds and after _____ seconds.
Explain what 48t represents in the given equation.
The car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.
The 48*t part means the number of feet that the car moves in t seconds
At what times is the car at 60ft from you?We know that the absolute value equation that models the distance is:
d(t) = |300 - 48*t|
Then what we need to solve is d(t) = 60, this is:
d(t) = 60 = |300 - 48*t|
That absolute value equation can be represented in two forms:
300 - 48*t = 60
300 - 48*t = -60
Solving these two we get the two times at which the car is at 60ft from you.
-48*t = 60 - 300
t = (60 - 300)/(-48) = 5
t = (-60 - 300)/(-48) = 7.5
So the car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.
The 48*t part means the number of feet that the car moves in t seconds.
