Step-by-step explanation:
im adding an answer so u can giveee the guy brailiestz
Answer:
376.8 m²
Step-by-step explanation:
The formula for finding the surface area of a cylinder is SA=2πr²+2πrh, where r is the radius of the base and h is the height of the cylinder. Using the diameter of the base, we can first calculate that the radius of the base is 10/2=5 meters. Then, we can plug our values into the equation.
SA=2πr²+2πrh
SA=2π(5)²+2π(5)(7)
SA=2π(25)+2π(35)
SA=50π+70π
SA=120π
Because the question asks us to use 3.14 for π, we plug that into our equation.
SA=120(3.14)
SA=376.8 m²
I hope this helps!

Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
please please help asap
Answers
Answer: 2000
Step-by-step explanation:
The following can be gotten from the question:
Principal = Unknown
Rate = 6%
Time = 6 years.
Interest = 720
Note that: Interest = PRT / 100
720 = (P × 6 × 6) / 100
720 = 36P / 100
720 × 100 = 36P
72000 = 36P
Principal = 72000 / 36
Principal = 2000
The amount that he borrowed is 2000.

Oy - 16 = S(x - 2)
Oy - 16 = 3x - 2
3- 16 = S(x - 2)
The relationship is non-linear
Answers
Given:
Table of values.
To find:
The equation in point slope form.
Solution:
From the given table it is clear that, the relationship is linear because the rate of change is constant because if x-value increases by 2 then y-values increases by 16.
Consider any two points from the table, i.e., (2,16) and (4,32).
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]Slope=\dfrac{32-16}{4-2}[/tex]
[tex]Slope=\dfrac{16}{2}[/tex]
[tex]Slope=8[/tex]
The point is (2,16) and the slope is 8, so the point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-16=8(x-2)[/tex]
Therefore, the relationship is linear and point slope form is [tex]y-16=8(x-2)[/tex].

y - 16 = 8(x - 2)

PLEASE HELP Michaels home is 12 feet below sea level in his mothers home is 12 feet above sea level Michael says their homes are at opposite elevation is because they are in opposite directions is he correct? Explain. I only have 2 more days to finish my work!
Answers
Answer:
Yes, he is correct
Step-by-step explanation:
Represent Michael's home with M and his mother's with H
So, we have:
[tex]M = 12\ ft (below)[/tex]
[tex]H = 12\ ft (above)[/tex]
Required
Is Michael correct?
First, we get the numeric values of the given parameters.
Below sea level means negative:
So:
[tex]M = 12\ ft (below)[/tex] will be rewritten as:
[tex]M = -12[/tex]
Above sea level means positive:
So:
[tex]H = 12\ ft (above)[/tex] will be rewritten as:
[tex]H = 12[/tex]
Two numbers [tex]A\ and\ B[/tex] are said to be opposite if [tex]A + B=0[/tex]
For Michael to be correct:
[tex]M + H = 0[/tex]
Substitute values for M and H
[tex]-12 + 12 = 0[/tex]
[tex]0 = 0[/tex]
Hence, Michael is correct

You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...

the length of a rectangular feild exceeds its breadth by 15m and perimeter is 90m. Find its area
Answers
Answer:
450
Step-by-step explanation:
Length = l
Breadth = b
l = 15 + b
Perimeter = 90
Perimeter = 2(l + b)
90 = 2(15 + b + b)
90 = 2(15 + 2b)
90 = 30 + 4b
90 - 30 = 4b
60 = 4b
60/4 = b
15 = b
Hence, l = 15 + 15 = 30
Area = l * b
Area = 30 * 15
Area = 450 unit²
