Answer: 2.456 x 10^11

Step-by-step explanation:

You move the decimal to the left until there’s no more zeroes

Answer:

there :D

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

2.456 ×  10  to the power of 11

Answer:

0.875

Step-by-step explanation:

you just divide 7 by 8, and you would get 0.875

7/8=0.875

Answer: 2 terms

Step-by-step explanation:

There are two terms because

One is __x the other is the constant

9x + 4 - 3x + 7

6x + 4 - 7

6x - 3 has two terms

If the given mathemtical expression is simplified completely, the expression would contain 2 terms.

Given this expression: 9x + (4 – 3x) + 7

Remove the brackets : 9x + 4 - 3x + 7

Add similar terms: 6x + 11

Answer:

volume of cylinder= pie × radius square× height

= 22/7×4×20

=1760/7

=251.42cm

Answer:

using 3 for pi it's V = 960cm^3

Step-by-step explanation:

R is the radius, which as stated, is half the diameter.

r = 8cm / 2 = 4cm

H is the height, which is shown to be 20cm

h = 20cm

V = pi*r^2*h

V = pi*(4cm)^2*20cm

substituting 3 for pi as requested.

V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3

Answer:

x=1

Step-by-step explanation:

you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.

7x-10+10=3x-6+10

now it leaves you with 7x=3x+4

Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.

7x-3x=3x-3x+4

how it leaves you with 4x=4

now you divide both sides by 4

4/4x=4/4

Hence, x=1

Answer:

standard form: 4x - 4 = 0

factorisation: 4(x - 1) = 0

solutions: x = 4/4 = 1

therefore, x is 1

Answer:

9x+2

Step-by-step explanation:

It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.

(2x+2)+(3x+1)+(4x-1)

2x+2+3x+1+4x-1

Combine like terms.

2x+3x+4x=9x

2+1-1=2

Left with 9x+2 as your perimeter binomial.

Answer:

-6665

Step-by-step explanation:

The given GP is :

1, -6, 36, ...

Number of terms = 6

The sum of n terms of a GP is given by :

[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]

Here,

a = 1, n = 6, r = 36/-6 = -6

So,

[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]

So, the sum of th GP is -6665.
