Answer:

a9= 59049

Step-by-step explanation:

Find the r.

R= 81/-27

R= -3

a1= 9

a2= -27

a3= 81

a4= 81*-3= -243

a5= -243*-3= 729

a6= 729*-3= -2187

a7= -2187*-3= 6561

a8= 6561*-3= -19683

a9= -19683*-3= 59049

Answer: For first blank: GNS

P = N G = P S = R

Answer:

t ≤ -135

Step-by-step explanation:

multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.

Answer:

Assuming you're talking about the angles of a triangle, X would be [tex]34^{.}[/tex]

Step-by-step explanation:

The sum of the angles in a triangle is 180, 180 - 32 - 80 = 68, [tex]\frac{68}{2}[/tex] is 34, so X is equal to [tex]34^{.}[/tex].

Question:A cone and a cylinder have the same base area. They also have the same curved surface area. If the height of the cylinder is 3m, then the slant height of the cone (in m) is

Answer:

Given the radius of cylinder and cone are the same because there base areas are same.

Curved surface of cylinder = curved surface area of the cone

∴2πrh=πrl

∴l=2h

Given, height of cylinder =3 cm

Therefore, slant height of cone =6 cm

The volume of the cone is 22π.

Volume of a cylinder = πr²h

55π = πr²(5)

55π = 5πr²

r² = 55π/5π

r² = ✓11

r = 3.3

The volume of the cone will be:

= 1/3πr²h

= 1/3 × π × 3.3² × 6

= 1/3 × 11 × 6 × π

= 22π

Answer:

h = 6 cm

Step-by-step explanation:

Volume of cylinder = 54 π cm³

πr²h = 54π

π * 3 * 3 * h = 54π

[tex]h = \frac{54 \pi }{\pi *3*3}\\\\h= 6[/tex]

Answer:

$9.5

Step-by-step explanation:

All you have to do is divide 19 by 2 to get the cost of one pillow. I hope this helps :)

Answer:

$9.50

Step-by-step explanation:

P is Pillows

2P=$19.00

divide by 2 in both sides

P=$9.50

so 1 pillow costs $9.50

Answer:

Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Step-by-step explanation:

Let the first five multiples of ten be

10*1= 10

10*2= 20

10*3=30

10*4=40

10*5= 50

Suppose we chose 20 and 50.

Now multiplying 20 with 50 we get

20*50= 1000

IF we count the total number of zeros in the factors ( 20 and 50) they are 2.

But the number of zeros in the product (1000) are 3.

This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.

And multiplying 10 with 50 we get

10*50= 500

IF we count the total number of zeros in the factors ( 10 and 50) they are 2.

But the number of zeros in the product (500) are also 2.

This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.

Similarly multiplying 20 with 30 we get

20*30= 600

IF we count the total number of zeros in the factors ( 20 and 30) they are 2.

But the number of zeros in the product (600) are also 2.

This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total  number of zeros remain the same as in the factors.

So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Answer:

X actually equals 16 becaausw if yiu add 16+4 you get 20 and then you have to multiply 20 by 1 and you get 20 so x=16

Answer:

x = 16

I dont quite understand the x = 48 situation? But thats wrong if that's your answe

Step-by-step explanation:

So you have to find out what x is

in order to do that you have to work out the equation and whatever you do to one side you must do to the other side

simplify 1(x+4) = 20

x + 4 = 20

in order to get rid of 4 on one side you have to subtract it on both sides

so x = 16

Answer:

The answer to your question is R=1

Answer:

Step-by-step explanation:

Since this is a test/homework I'll give a hint.

For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.
