Answer:
Step-by-step explanation:
Since dividing any term by the previous term is constant this is a geometric sequence. In this case the common ratio is 18/6=54/18=3 and the first term a1=6
So a1=6 and r=3

Answer:
Prism A: 264; Prism B: 265.125
Step-by-step explanation:
✔️Surface area of the triangular prism = base area + Perimeter*Height of prism
Base area = ½*bh
b = 6 cm
h = 8 cm
Base area = ½*6*8 = 24 cm²
Perimeter of base = 6 + 8 + 10 = 24 cm
Height of prism = 10 cm
Surface area of the triangular prism = 24 + 24*10 = 264 cm²
✔️Surface area of rectangular prism = 2(LW + LH + HW)
L = 5.25 cm
W = 5.25 cm
H = 10 cm
Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)
= 265.125

Answer:
the perimeter is 21
Step-by-step explanation:
formula -
P = a + b + c + d you can find the length of your sides by looking at the units
P = 5 + 8 + 4 + 4 on the graph (just count how many squares makes the side
P = 21 you are looking for) ex: side a (the top line) is 5 units

y = 24 - 3x
A scientist might be interested in the x-intercept of this

Step-by-step explanation:
Let's think about how we can solve for ttt in the following equation:
\qquad 6t = 546t=546, t, equals, 54
We want to get ttt by itself on the left hand side of the equation. So, what can we do to undo multiplying by 6?
We should divide by 6 because the inverse operation of multiplication is division!
Here's how dividing by 6 on each side looks:
\begin{aligned} 6t &= 54 \\\\ \dfrac{6t}{\blueD{6}} &= \dfrac{54}{\blueD{ 6}}~~~~~~~~~~\small\gray{\text{Divide each side by six.}} \\\\ t &= \greenD{9}~~~~~~~~~~\small\gray{\text{Simplify.}} \end{aligned}6t66tt=54=654 Divide each side by six.=9 Simplify.
Let's check our work.
It's always a good idea to check our solution in the original equation to make sure we didn't make any mistakes:
\qquad \begin{aligned} 6t &= 54 \\ 6 \cdot \greenD9 &\stackrel{\large?}{=} 54\\ 54 &= 54 \end{aligned}6t6⋅954=54=?54=54
Yes, t = \greenD{9}t=9t, equals, start color #1fab54, 9, end color #1fab54 is a solution!
Solving a division equation using inverse operations
Now, let's try to solve a slightly different type of equation:
\qquad \dfrac x5 = 75x=7start fraction, x, divided by, 5, end fraction, equals, 7
We want to get xxx by itself on the left hand side of the equation. So, what can we do to cancel out dividing by 5?
We can multiply by 5 because the inverse operation of division is multiplication!
Here's how multiplying by 5 on each side looks:
\begin{aligned} \dfrac x5 &= 7 \\\\ \dfrac x5 \cdot \blueD{5} &= 7 \cdot \blueD{5}~~~~~~~~~~\small\gray{\text{Multiply each side by five.}} \\\\ x &= \greenD{35}~~~~~~~~~~\small\gray{\text{Simplify.}} \end{aligned}5x5x⋅5x=7=7⋅5 Multiply each side by five.=35 Simplify.
Let's check our work.
\qquad \begin{aligned} \dfrac x5 &= 7 \\\\ \dfrac{\greenD{35}}{5} &\stackrel{\large?}{=} 7\\\\ 7 &= 7 \end{aligned}5x5357

Step-by-step explanation:
A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.
Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons

The first one I'll do is Physics because you know the amount of girls and total amount of students. Use the equation x+19=33. Note that x is the amount of boys we are trying to find. All you need to do is simply subtract 19 from both sides to get x alone.
x + 19 = 33
-19 -19
x = 14
For the total that's going up and down, you can do this same process again, but just using x for girls instead of boys. Your equation should look like 47+x=80. Once again, subtract 47 from both sides.
47 + x = 80
-47 -47
x = 33
Now you can find whole row for boys. This equation will be a little longer, but it's still pretty easy. 18+x+14=47 is what we will be using. We first will need to combine like terms (the 18 and 14), then subtract it off from both sides to get x alone.
18 + x + 14 = 47
x + 32 = 47
-32 -32
x = 15
Moving onto the biology column, we'll be using the equation 15+x=21
15 + x = 21
-15 -15
x = 6
Now we can find out the girls column with this equation: x+6+19=33
x + 6 + 19 = 33
x + 25 = 33
-25 -25
x = 8
Lastly, we can find the chemistry column by just adding 18+8 to get 26.

An iron dinner bell is in the shape of an equilateral triangle with a side length of 8 5/8 inches. Find the length of the rod used to create the bell
Answer:
25 7/8inches
Step-by-step explanation:
The length of the rod is equal to the side length of the equilateral triangle
Let the length of the rod be x
Since an equilateral triangle has all its sides equal, its perimeter is expressed as;
P = x+x+x
P = 3x
Given x =8 5/8
P = 3(69/8)
P = 207/8
Express as mixed fraction
P = 25 7/8 inches
Hence the length of the rod used to create the bell is 25 7/8inches
A new motorcycle has a value of $8000 every year is value decreased by $500 which function can be used to find why the value of motorcycle in X years?
The function for the value of the motorcycle after x years are;
y = 8000 - 500x
y = -500x + 8000
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have given that new motorcycle has a value of $8,000. Every year its value decreases by $500.
Now, we have y = amount of the motorcycle
x = number of years
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Thus,
y = 8000 - 500x
y = -500x + 8000
