Answer:
A "fair" coin lands heads-up half of the time and "tails-up" half of the time.
For one flip, the probability of landing heads-up is 1/2.
Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.
So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.
Step-by-step explanation:
The probability that coin lands heads-up and the die shows a five is 0.083.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.
Given that, a person flip a coin and then roll a fair six-sided die.
The probability the coin lands heads-up is 1/2
The probability that die shows a five = 1/6
Now, the probability of an event = 1/2 × 1/6
= 1/12
= 0.083
Therefore, the probability that coin lands heads-up and the die shows a five is 0.083.

What is the surface area of a cylinder with base radius 4 and height 5?
Either enter an exact answer in terms of PI or use 3.14 for PI and enter your answer as a decimal.
Step-by-step explanation:
S = (2 * pi * r^2) + (2 * pi * r * h)
S = (2 * pi * 4^2) + (2 * pi * 4 * 5)
S = (32 pi) + (40 pi) = 72pi = 226.08 ANS.
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?
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
Let x and y be real numbers such that x^2 + y^2 = 4(x + y). Find the largest possible value of x.
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

Then she checks out on the other bank, a big stone (point B) or something (which is not too far from her), she then goes along the bank to the point C so that BC is perpendicular with the bank.
If she can mark down the distance she walked AC and the angle BAC, then she can calculate the width of river (AB) by formula:

A painter charges $12 per hour plus $50 for every job. If he made $194 on a job, how many hours did he work?
Answer:
12
Step-by-step explanation:
194-50=144
144/12=12
Answer:
12 hours
Step-by-step explanation:
We can start with an equation: 12x+50 = 194 (x being number of hours)
solving gives 12x = 144
x = 144/12
x = 12

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

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

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
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.

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.

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
