PLEASE HELP The diameter D of a sphere is 19 m. Calculate the sphere's surface area A.
Use the value 3.14 for at, and round your answer to the nearest tenth.
Answers
Answer:
A = 1,133.5 m³
Step-by-step explanation:
Surface area of a sphere, A = 4πr²
π = 3.14
Radius, r = diameter / 2
= 19 m / 2
= 9.5 m
Surface area of a sphere, A = 4πr²
A = 4 * 3.14 * (9.5)²
= 4 * 3.14 * 90.25
= 1,133.54
A = 1,133.54 m³
To the nearest tenth
A = 1,133.5 m³

Step-by-step explanation:
Since this is a linear pair, it equals to 180 degrees.
7x + 37 + 4x = 180
11x + 37 = 180

Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
O) Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
O) Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
O) Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.

If x=0.01, then f(x)=0.223495106

x * 6 = 8 * ( x - 1 )
Or 6x = 8 ( x - 1 )
Now we solve for
Step 1 distribute the 8
8 * x = 8x
8 * -1 = -8
We now have 6x = 8x - 8
step 2 subtract 8x from each side
6x - 8x = -2x
8x - 8x cancels out
we now have -2x = -8
step 3 divide each side by -2
-2x / -2 = x
-8 / - 2 = -4
we're left with x = 4

375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many fish are in the school now
Answers
Answer:
The answer is 444.
Step-by-step explanation:
First, you do 375 - 47 because 47 swam away, decreasing the amount of fish that are swimming in a school. Then, 116 fish come back to swim so you add 116 to get 444.
There are 444 fish in the school now.
What is Unitary Method?The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.
The unitary approach is used when we have several goods with varying values in our possession. To get the value of one unit, we simply divide the total value by the number of units.
We have,
375 fish are swimming in a school.
First, 47 fish swim away.
Then 116 more fish join the school.
So, the number of fish in the school now
= 375 - 47 + 116
= 444 fish
Thus, there are 444 fish in school now.
