Step-by-step explanation: Here we can see 1 -> 3 and 8 -> 24 and 9 -> 27.
These are all being multiplied by 3 therefore when you put N in it is triples and becomes 3n
Write an equation for the line that is parallel to the given line and that passes through the given point. y = 1/2x - 8; (-6, -17).
Answer:
y = 1/2x - 14
Step-by-step explanation:
Parallel lines have the same gradient
So,
gradient for second line = gradient of the first line = 1/2
Also,
the line passes through (-6,-17)
So, we can find the y-intercept by substitution
y = mx + c
-17 = (1/2 * -6) + c
-17 = -3 + c
c = -14
So,
the equation is y = 1/2x - 14

Calcula el perímetro y el área de un hexágono de 4 metros de lado y 3.46 m de apotema
Answer:
[tex]P=24\: m[/tex]
[tex]A=41.52 \m^{2}[/tex]
Step-by-step explanation:
El perímetro de un hexágono se calcula de la siguiente manera:
[tex]P=6*l[/tex]
l es el lado del hexágono l = 4 m
Entonces P es:
[tex]P=6*4=24\: m[/tex]
El área del hexágono puede calcularse de la siguiente manera:
[tex]A=\frac{P*Ap}{2}[/tex]
P es el perímetro = 24 m
Ap es la apotema = 3.46 m
El Area sera:
[tex]A=\frac{24*3.46}{2}[/tex]
[tex]A=41.52 \m^{2}[/tex]

Which equation gives the volume of the sphere?
O V=2/3(27ń)
O V=4/3(27)
O V= 2/3 (27)
O V= 4/3 (27ń)
Answer:
The correct option is (b).
Step-by-step explanation:
A sphere and a cylinder have the same radius and height,
The volume of cylinder is,
[tex]V=\pi r^2 h\\\\V=\pi r^3[/tex]
ATQ,
The volume of cylinder is 27 cubic units.
[tex]\pi r^3 = 27[/tex]
The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\times 27[/tex]
So, the correct option is (b).

Please help me with his one I don't get it . Nick estimates that he will need $4400 per year for tuition at the college he wants to attend . Nick's grandparents will be able to pay for 45% of his expenses. If Nick has 3 years to save for the rest of his tuition for his first year , what is the minimum amount he has to save each month to reach his goal?
Answer:
$67.22 each month
Step-by-step explanation:
Find how much Nick's grandparents will pay for by multiplying 4400 by 0.45:
4400(0.45)
= 1980
Subtract 1980 from 4400 to find how much Nick will have to save:
4400 - 1980
= 2420
Nick has 3 years to save for his tuition, meaning that he has 36 months to save (since there are 12 months in a year).
Find how much he has to save each month by dividing 2420 by 36:
2420/36
= 67.22
So, Nick will have to save approximately $67.22 each month

The price of a bracelet is $1.29. If the tax rate is 5%, find the total cost of the bracelet
Answer:
Cost of bracelet = $1 and 35 cents
Step-by-step explanation:
Price before tax = $ 1.29
Tax Price = 5% of 1.29
[tex]=\frac{5}{100} \times 1.29\\\\= 6.45 \times \frac{1}{100} \\\\= 0.0645[/tex]
Therefore price after tax = 1.29 + 0.06245 = 1.3545
Ans : cost of bracelet = $1 and 35 cents

sum of three consecutive odd number is 69 find the prime number out
Answer:
23 is the prime number
Step-by-step explanation:
let n, n + 2, n + 4 be the consecutive odd numbers, then
n + n + 2 + n + 4 = 69 ← simplify left side
3n + 6 = 69 ( subtract 6 from both sides )
3n = 63 ( divide both sides by 3 )
n = 21 , then
n + 2 = 21 + 2 = 23 and n + 4 = 21 + 4 = 25
The 3 numbers are 21, 23, 25 with prime number 23
Answer:
[tex]let \: the \: first \: number \: be \: x \\ x + (x + 2) + (x + 4) = 69 \\ 3x + 6 = 69 \\ 3x = 63\\ x = 21 \\ first = 21 \\ second = 21 + 2 =23 \\ third = 21+ 4 = 25\\ prime \: number \: is \: 23 \\ { \boxed{prime = 23}}[/tex]

Find the equation of the line that passes through the points A (2, 3) and B (5, -7)
Answer:
10x+3y=29
Step-by-step explanation:
Given points:(x1,y1)=(2,3)
(x2,y2)=(5,-7)
We know, the equation of line passing through two points is given by,
y-y1={(y2-y1)/(x2-x1)}*(x-x1)
Hence,y-3={(-7-3)/(5-2)}*(x-2)
or,y-3=(-10/3)*(x-2)
or,3y-9= -10x+20
or,3y+10x=20+9
or,10x+3y=29 is the required equation.
Write an exponential function in the form y = ab" that goes through points (0,7)
and (9,3584).
Answer:
Step-by-step explanation:
I'm going to assume you meant y = ab^x. If this is not correct, leave a comment.
x = 0
y = 7
7 = a * b^0
anything to the zero power is 1
y = a*b^0
y = a*1
7 = a
So far what you have is
y = 7 * b^x
Now let
x = 9
y = 3584
3584 = 7 * b^9 Divide by 7
3584/7 = b^9
512 = b^9
If you knew how to use logs, that would be the surest way to do this question. However I'm going to make an assumption again and assume that you have not taken those yet.
So the easiest way is to find out what raised to the 9th power will equal 512
Could b = 5?
5^9 = 1 million 9 hundred thousand something. 5 is far too big. Make sure you understand why. 1 million is far greater than 512
So let's try b = 3
3^9 = 19 thousand which is still far too big. 19 thousand something is far larger than 512.
We have just one more number that we can try.
2^9 = 512 and we have it
Answer y = 7*2^x
