If you square a googol, how many zeros will the answer have? Show your reasoning.

Answers

Answer:

200 zeros

Step-by-step explanation:

1 googol is the number 1 followed by a hundred zeros, right? Right. Using 'Laws of Indices', for instance, 10^2=100, ie 10×10=100. The number of zeros will always be the sum of the number of zeros of the multiplier and multiplicand. More example, 100×100=10000. So, I think it's reasonable to say that 1 googol×1 googol= the number one followed by two hundred zeros ‍♀️

A.one line


B.parallel lines


C.intersecting lines

Answers

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

[tex]y = -2\cdot x - 5[/tex]

[tex]6\cdot x + 3\cdot y = -15[/tex]

[tex]3\cdot y = -6\cdot x - 15[/tex]

[tex]y = -2\cdot x - 5[/tex]

The second equation is identical to the first one, which means that there is just one line.

10m + 40 = 9m + 27

10m - 9m = 27 - 40

m = -13

Answer:

m = - 13

Step-by-step explanation:

2/3 (m + 4) = 1/5 (3m+9)

2/3m + 8/3 = 3/5m + 9/5

2/3m - 3/5m = 9/5 - 8/3

10/15m - 9/15m = 27/15 - 40/15

1/15m = - 13/15

m = - 13/15 / 1/15

m = - 13/15 * 15

m = - 195/15

m = - 13

What is a relative frequency?

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the frequency cell by the total frequency.

As per the relative frequency table, the correct statements are:

Eve's table shows that those who enjoy dancing are likely girls. Bob's table shows that boys are likely to not enjoy dancing. The percentage of someone being a girl, given that the person enjoys dancing is lower than the percentage that someone enjoys dancing, given that the person is a girl.

Let x and y be real numbers such that x^2 + y^2 = 4(x + y). Find the largest possible value of x.

Answers

Answer:

The largest possible value of x is 2 + √8

Step-by-step explanation:

Given;

x² + y² = 4(x + y)

This is an equation of circle

x² + y² = 4x + 4y

x²- 4x + y² - 4y = 0

complete the square by taking half of coefficient of x and y, then add the squares to both sides;

x²- 4x + (-2)² + y² - 4y + (-2)² = (-2)² + (-2)²

factorize

(x - 2)² + (y - 2)² = √8

This circle has its center at  (2, 2)  with a radius of  √8

The largest x-value occurs at the right end of the circle = x value of the center plus the radius = 2 + √8

Step-by-step explanation:

When we solve it, the first step is [tex]-6x+1=7-6x[/tex].

-6x+6x is 0, so there is no solution

Answer:

There are no solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(3x)+1=7−6x

Step 1: Simplify both sides of the equation.

−2(3x)+1=7−6x

−6x+1=7+−6x

−6x+1=−6x+7

Step 2: Add 6x to both sides.

−6x+1+6x=−6x+7+6x

1=7

Step 3: Subtract 1 from both sides.

1−1=7−1

0=6

On an average day, a horse might drink 50 L a sheep might drink 4 l and a chicken might drink 200 mL how much water would a farm need with 4 horses 8 sheep and 16 chickens need for a day

Answers

Answer:

The farm would need 235.2 liters daily for 4 horses, 8 sheep and 16 chickens.

Step-by-step explanation:

The daily consumption of water in the farm must be:

[tex]x = (4\,horses)\times \left(50\,\frac{L}{horse} \right) + (8\,sheep)\times \left(4\,\frac{L}{sheep} \right) + (16\,chickens)\times \left(0.2\,\frac{L}{chicken} \right)[/tex]

[tex]x = 235.2\,L[/tex]

The farm would need 235.2 liters daily for 4 horses, 8 sheep and 16 chickens.

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 16,307 gallons of water, and is leaking at a rate of 4 gallons per day. If Mike does not replace the water that has leaked from the pool, how many gallons of water will remain in the pool after 192 days?

Answers

Answer:

15,539 gallons will remain after 192 days

Step-by-step explanation:

16,307 - 4x = y

Plug in 192 for x since that's how many days will have passed.

16,307 - 4(192) = y

4 x 192 = 768

Then, subtract 768 from 16,307 to see how many gallons will remain.

16,307 - 768 = 15,539

Answer:

15,539 gallons

Step-by-step explanation:

16,307 - 4x = y;

16,307 - 4(192) = y;

4 x 192 = 768;

16,307 - 768 = 15,539
