Find the surface area of the cone in terms of pi.​

Answer:

C) x + 9 = x + 9

Step-by-step explanation:

An equation has infinite solutions if can simplify to the format: a = a, where a is any number.

This is because it means that any value you plug into x will give you the same true equation and answer.

C meets these requirements as it is already in format a=a, but if we further simplify it, we can see how it works:

Subtract x from both sides: 9=9

Subtract 9 from both sides: x=x

Subtract (x+9) from both sides: 0=0

We can see that C has infinite solutions because any value you put in for x, it will cancel itself out when you solve it, therefore it has infinite solutions.

E.g. x=5

(5) + 9 = (5) + 9

14 = 14

E.g. x=-25

(-25) + 9 = (-25) = 9

-16 = -16

We can also answer this question by solving all the other equations:

A) 2x + 5 - 2x = 2x - 2x + 8

5 = 8

This is not true so this equation has NO solutions.

B) 5x - 2x - 1 = 2x - 2x + 4

3x - 1 + 1 = 4 + 1

3x = 5

x = 5/3 (One solution)

D) I think you've missed a sign here, but it is solvable either way to get to one solution.

Answer:

V = 430 mL

Step-by-step explanation:

Given that,

The volume of the shampoo bottle, V = 0.43 L

We need to find how many milliliters of shampoo is contained in the bottle.

We know that,

1 L = 1000 mL

If we want to convert 0.43 L to mL we can use the unitary method. So,

0.43 L = 0.43 × 1000 mL

= 430 mL

So, 430 mL is contained in the bottle.

Reduction means the action or fact of making something smaller or less in amount, degree, or size

In mathematics, reduction refers to the rewriting of an expression into a simpler form. For example, the process of rewriting a fraction into one with the smallest whole-number denominator possible (while keeping the numerator a whole number) is called "reducing a fraction".

Step-by-step explanation:

An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. ... A decrease of 100% means the final amount is zero (100% – 100% = 0%).

Answer:

Seven billion , one hundred thirteen million, six hundred and two thousand , five hundred and sixty six.

Step-by-step explanation:

B, HM  TM,   M    Hth,  TTh   Th ,       H    T     O

7,    1     1,       3     6,     0       2,        5     6      6

Seven billion , one hundred thirteen million, six lac, two thousand , five hundred and sixty six.

Where

B= billion

HM = hundred million

TM  = ten million

M  = million

 HTh  = Hundred Thousand

TTh = Ten thousand

 Th = thousand

 H   = hundred

T     = tens

O= ones or units

In system international each category in further divided into units, hundreds and thousands.

We see that we have thousand,  ten and then hundred thousand .

Similarly we have million, ten and hundred million.

This continues for billions and so on.

Answer:

The value of a₂₇ is 294

Step-by-step explanation:

a₁₃ = 254

a₃₃ = 654

Now,

a₁₃ = 254 can be written as

a + 12d = 254 ...(1) and

a₃₃ = 654 can be written as

a + 32d = 654 ...(2)

Now, from equation (2) we get,

a + 32d = 654

a + 12d + 20d = 654

254 + 20d = 654 (.°. a + 12d = 254)

20d = 654 - 254

20d = 400

d = 400 ÷ 20

d = 20

Now, for the value of a put the value of d = 20 in equation (1)

a + 12d = 254

a + 12(20) = 254

a + 240 = 254

a = 254 - 240

a = 14

Now, For a₂₇

a₂₇ = a + 26d

a₂₇ = 14 + 9(20)

a₂₇ = 14 + 180

a₂₇ = 294

Thus, The value of a₂₇ is 294

Answer:

210

Step-by-step explanation:

x = num of adults

x + 7.5x = 238

8.5x = 238

x = 28

#students = 238-x

                 = 210

Answer:

First, let's define acceleration.

Acceleration defines how the velocity changes, and remember that velocity is a vector.

Then V = 10 m/s and V' = -10m/s are clearly different, while the speed is the same, one describes motion in one direction and the other describes motion in the opposite direction.

Where speed is the absolute value of the velocity:

S = IVI = I10 m/sI = 10 m/s

S' = IV'I = I-10 m/sI = 10m/s

If you have positive velocity and positive acceleration, then your velocity increases (meaning that your speed increases)

if you have positive velocity and negative acceleration, then your velocity decreases (meaning that your speed decreases)

if you have negative velocity and positive acceleration, then your velocity increases (meaning that your speed decreases)

if you have negative velocity and negative acceleration, then your velocity decreases (meaning that your speed increases)

Now, if you are in a freeway with no traffic, your velocity may be larger than 30 m/s (here we assume that you move in the positive direction, then your velocity is positive)

Then you see the sign, and you know that you need to decrease your velocity, meaning that you need to have negative acceleration until your velocity is 30 m/s or lower.

Concluding, the acceleration will be opposite to the direction of the velocity.
