Answers
Answer:
528 in.²
Step-by-step explanation:
Surface area of the figure = (surface area of the smaller rectangular prism + surface area of the bigger prism) - area of 1 of the base of the smaller rectangular prism
✔️Surface area of the bigger rectangular prism = 2(WL + HL + HW)
= 2(10*12 + 5*12 + 5*10) = 2(120 + 60 + 50)
= 2(230)
Surface area of bigger rectangular prism = 460 in.²
✔️Surface area of the smaller rectangular prism = 2(WL + HL + HW)
= 2(2*2 + 8*2 + 8*2) = 2(4 + 16 + 16)
= 2(36)
Surface area of smaller rectangular prism = 72 in.²
✔️area of 1 of the base of the smaller rectangular prism = L*W = 2*2 = 4 in.²
✅Surface area of the figure = (460 + 72) - 4
= 532 - 4
= 528 in.²

A population of 2000 fish increases at an annual rate of 7.5%. Write the model, then predict how
many fish will there be in 10 years?
Answers
Answer:
The model is [tex]P(t) = 2000(1.075)^{t}[/tex].
There will be 4122 fish in 10 years.
Step-by-step explanation:
Exponentially increasing population:
An exponentially increasing population can be represented by the following model:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(t) is the population after t years, P(0) is the initial population, and r is the growth rate, as a decimal.
A population of 2000 fish increases at an annual rate of 7.5%.
This means that [tex]P(0) = 2000, r = 0.075[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2000(1+0.075)^t[/tex]
[tex]P(t) = 2000(1.075)^{t}[/tex]
This is the model.
How many fish will there be in 10 years?
This is P(10).
[tex]P(t) = 2000(1.075)^{t}[/tex]
[tex]P(10) = 2000(1.075)^{10} = 4122[/tex]
There will be 4122 fish in 10 years.

A line passes through the point (-8,7) and has a slope of 5/4 write equation in slope intercept form
Answers
Answer:
[tex]y=\frac{5}{4} x[/tex]+17
Step-by-step explanation:
Okay for this you take the point (-8+7) and plug it into the equation getting you this 7=[tex]\frac{5}{4}[/tex](-8)+b
If you multiple [tex]\frac{5}{4\\}[/tex] by -8 you get -10
You then add -10 to the other side to get 17
that means 17=b
meaning you get [tex]y=\frac{5}{4} x[/tex]+17 by plugging in 17 to b

0.392 is what percent of 28?
Pleasee
Answers
Answer:
28% of 0.392=0.10976
Step-by-step explanation:
1. We assume, that the number 0.392 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 0.392 is 100%, so we can write it down as 0.392=100%.
4. We know, that x is 28% of the output value, so we can write it down as x=28%.
5. Now we have two simple equations:
1) 0.392=100%
2) x=28%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
0.392/x=100%/28%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for what is 28% of 0.392
0.10976

Find the 18h term of the arithmetic sequence whose common difference is d=4 and whose first term is a, =3.
Answers
Answer:
the 18th term is 71
Step-by-step explanation:
The general form for any term "n" in an arithmetic sequence is:
a(n) = a1 + (n-1) * d
where "d" is the common difference.
So, in our case we have:
a(n) = 3 + (n-1) *4
Therefore, the 18th term will be:
a(18) = 3 + (18 - 1) 4 = 3 + 17 * 4 = 71
