The area of the base of the regular quadrilateral pyramid is 36 cm2 and the area of a lateral face is 48 cm2. Find: Surface area of the pyramid

Answers

Surface Area (SA) = Base Area (Ab) + Lateral Area (AL)

Base Area = 36cm^2
Lateral Face Area = 48cm^2

*If this is a quadrilateral pyramid, then it has 4 lateral faces, so just multiply the "one" lateral face by 4.

Lateral Area (AL) = 4 x Lateral Face Area
-> AL = 4 x 48 = 192 cm^2

So:

SA = Ab + AL
-> SA = 36 + 192
-> Surface Area = 228 cm^2

Answer:

Identifying the Factored Form of a Trinomial Which expression is the factored form of x2 – 7x + 10?

Answers

let's call x^2: a; -7x: b; and 10:c
So what I do in this case:
when the number squared does not have a coefficient in front, I ask myself, what does A times C equal
the answer is 10 --> now what factors of ten, add up to -7 (the factors can be negative and/or positive)
the answer is -2 and -5
so with this, you do: (x-2)(x-5)
there's your answer, i hope that makes sense

f. subtracting 4.2 from the least number in the set

Answers

The median of a set of three numbers is x. there at least three numbers in the set. Write an algebraic expression, in terms of x, to represent the median of the new set of numbers obtained by
a] adding 1/8 to every number in the set
Let the numbers be w,x,y
adding 1/8 to the number we get:
(w+1/8),(x+1/8),(y+1/8)
the new median will be:
(x+1/8)

b. subtracting 9 1/4 from every number in the set
Given our data set is w,x,y
adding 9 1/4 to each number we get:
(w+9 1/4),(x+9 1/4), (y+9 1/4)
thus the new median is:
(x+9 1/4)

c]multiplying -5.8 to every number in the set and then adding 3 to the resulting numbers
Multiplying each number by -5.8 we get:
(-5.8w),(-5.8x),(-5.8y)
adding 3 to these numbers we get:
(-5.8w+3),(-5.8x+3),(-5.8y+3)
thus the new median is:
(-5.8x+3)

d]dividing every number in the set by 0.5 and then subtracting 1 from the resulting numbers
dividing each number in our set by 0.5 we get:
(w/0.5),(x/0.5),(y/0.5)
this will give us:
(2w),(2x),(2y)
then subtracting 1 from the above we get:
(2w-1),(2x-1),(2y-1)
thus the median will be:
(2x-1)

e. adding 7.2 to the greatest number in the set
from our set:
w.x.y
the greatest number is y, then adding 7.2 to the greatest numbers gives us:
y+7.2
thus new series is:
w,x,y+7.2
thus the median is:
x
Conclusion
The median doesn't change

f. subtracting 4.2 from the least number in the set
from our set w,x,y; subtracting 4.2 from the least number gives us:
w-4.2
the new set is:
w-4.2, x, y
thus the new median is x
Conclusion
The median doesn't change

A fisherman borrowed 85,000 over 25 years at 13.5% p.a. interest compounded monthly. At the end of the seventh year, interest rate climbed to 15% p.a. compound and fisherman's repayments were increased to allow him to complete the repayments by the end of 25 years term.

a. how much did the fisherman owe at the end of the first 7 years?
b. what were his monthly repayments for remaining 18 years?
c. how much interests in total did the fisherman pay at the end of the 25 years long.

Answers

Amount borrowed, A1 = 85,000
Rate, i, for the first 7 years = 13.5% = 0.135
Rate, i, for the remaining 18 years = 15% = 0.15

Part (a): Amount owed after 7 years
Without interest rate, monthly payment, Po= 85,000/(12*25) = 283.33
After 7 years, principal amount remaining = 85,000 - (283.33*7*12) = 61,200.

Therefore, the amount owed after 7 years, A2 = 61,200

Part (b): Monthly repayment for the rest of 18 years
Rate, i = 15% = 0.15

Monthly payment, P(18) = A1*D2
D2 = {0.15/12}/{1-(1+0.15/12)^-12*25} = 0.01281

Then,
P(18) = 85,000*0.01281 = 1088.71

Part (c): Total interest paid
I =[ I(7) + I(18)] - A1

I(7) = P(7)*7*12 + P(18)*18*12

Now, P(7) = A1*D1
D1 = {0.135/12}/{1-(1+0.115/12)^-12*25} = 0.01165

Then,
P(7) = 85,000*0.01165 = 990.25

Therefore,
I = [990.25*7*12 + 1088.71*18*12] -85,000 = 318,341.50 -85,000 = 233,341.50

A kennel has 100 dogs in total, some are puppies and some are adult dogs. the ratio of puppies to adults in a kennel is 1:4 how many puppies are there

Answers

Puppies : Adults = 1 : 4

Total parts = 1 + 4 = 5

5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs

Answer: 20 puppies

Final answer:

The number of puppies in the kennel is 20, given that the ratio of puppies to adult dogs is 1:4 out of a total of 100 dogs.

Explanation:

In the given scenario, the number of dogs in the kennel is 100, and the ratio of puppies to adult dogs is 1:4. This means that for every one puppy, there are four adult dogs. Therefore, the total number of sections we have is 1 (for puppies) + 4 (for adult dogs), which equals 5. To find out how many puppies there are, we divide the total number of dogs by the total sections, and multiply by the number of sections for puppies. Therefore, the calculation would be as follows:

Divide the total number of dogs (100) by the total sections (5):
This gives us 20 dogs per section. Multiply this by the number of sections for puppies (1):
This gives us 20 puppies in the kennel.

Suppose the volume of a right circular cylinder is 225 cubic meters and the area of its base is 25 square meters. What is the height of the cylinder?

Answers

Volume of a cylinder: [tex] \pi [/tex]r²h

First we need to find the radius of the cylinder. It's area is 25. We can plug that into the area formula, [tex] \pi [/tex]r² and solve for r (radius).

[tex] \pi [/tex]r² = 25
Divide both sides by [tex] \pi [/tex].

r² = 7.96
Square root both sides.

r = 2.82 meters

Now plug the radius + volume into the volume formula and solve for h.
[tex] \pi [/tex]2.82²h = 225
Divide by [tex] \pi [/tex].

2.82²h = 71.62
Divide by 2.82².

h = 9

The height of the cylinder is 9 square meters.

The height of the cylinder will be 9 meters.

What is the volume of a right circular cylinder?

Let r be the radius, h be the height, and A be the area of the cylinder. Then the volume of the cylinder will be given as,

V = π r²h cubic units

V = Ah cubic units

Suppose the volume of a right circular cylinder is 225 cubic meters and the area of its base is 25 square meters. Then the height of the cylinder is calculated as,

225 = 25h

h = 225 / 25

h = 9 meters

If the least value of n is 4, which inequality best shows all the possible values of n?

Answers

Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.

Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower.

When you write something like n ≤ 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n.

But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4.

There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.

Does the median or mean better represent the data? And why? {20,28,35,40,132}

Answers

Okay so median is the number in the middle and mean is when you add them all up and divide by how many numbers there are

20,28,35,40,132

So 35 is the median
and the mean is 20 + 28 + 35 + 132 + 40 = 255 / 5 = 51

the mean is a better way to represent the data because it does not just pick a number from the set of numbers it calculates the average
