Answer: The surface area is 452.39in²
Step-by-step explanation:
Formula
A=4πr²
d= 2 r
Solving for A
A=πd²=π·12²≈452.38934in²
The surface area of a sphere that has a diameter of 12 inches is 452.39 in².
To solve the question, we need to know what the surface area of a sphere is.
What is the surface area of a sphere?The surface area of a sphere is given by A = 4πr² where
r = radius of sphere = d/2 where d = diameter of sphere.Given that d = 12 inches, r = d/2 = 12 in/2 = 6 in
Substituting the value of r into A, we have
A = 4πr²
A = 4π × (6 in)²
A = 4π × 36 in²
A = 144π in²
A = 452.39 in²
So, the surface area of a sphere that has a diameter of 12 inches is 452.39 in².

Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pairs will each friend get?
Answer:
3 pears each
Step-by-step explanation:
3 bags of pears
5 pears in each
1=5
2=5
3=5
thats 15 pears
15/4=3.75 (so its just 3)
The number of pears each friend get will be 3.75 pears for each friend.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Jen has 3 bags of pears. Each bag has 5 pears. Then the total number of the pears will be given by the multiplication of the numbers 3 and 5.
Total pears = 3 x 5
Total pears = 15 pears
If Jen gives the same number of pears to 4 friends.
Then the number of pears each friend gets will be
⇒ 15 / 4
⇒ 3.75 pears for each friend
Thus, the number of pears each friend get will be 3.75 pears for each friend.

Find the solution to the system of equations given below:
x=-4
-5x-4y=16
PLS HELP
Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.

Janet's car insurance payment decreases by $30 each year. Which expressions represent the total change in her payment, in dollars, after 4 years?
Answer:
The change after five years is equal to -$100
Step-by-step explanation:
If the insurance payment is equal to P = N dollars, where P is a real number, we know that after one year, the payment decreaces by $20, so the new payment is:
P = N - $20
Then, after 5 years, the $20 dollars are discounted five times, so the payment will be:
P = N -5*$20 = N - $100
Then the total change after 5 years is equal to those $100 that are being subtracted in the last equation.
The arrow of this spinner was spun 60 times. On 45 out of 60 times, the arrow landed on a section with a multiple of 4. What was the experimental probability of the arrow landing on a section labeled with a multiple of 4?
Experimental or Theoretical?
Answer:
Step-by-step explanation:
The experimental value of probability of the arrow landing on a section labeled with a multiple of 4 is 3/4 or 0.75
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The probability that the arrow lands on a section labeled with a multiple of 4 is an experimental probability since it is based on the results of an actual experiment or trial.
The experimental probability is given by:
Experimental probability = Number of times the event occurred / Total number of trials
In this case, the event is the arrow landing on a section labeled with a multiple of 4, and the total number of trials is 60.
From the given information, we know that the arrow landed on a section labeled with a multiple of 4 on 45 out of 60 times.
So the experimental probability is:
Experimental probability = 45/60
Simplifying:
Experimental probability = 3/4
Hence , the experimental probability of the arrow landing a multiple of 4 is 3/4 or 0.75

Moussa's family took a road trip to the Grand Canyon. Moussa fell asleep after they
had travelled 434 miles. If the total length of the trip was 700 miles, what percentage
of the total trip had they travelled when Moussa fell asleep?
Answer:
38%
Step-by-step explanation:
So first you need to find what 434/700 is because that is when she fell asleep. Divide each side by 2 to get 217/350. Use division to find the decimal. Once you are done with that, you get 0.62. You then subtract 0.62 from 1 because that is the amount of when she fell asleep. 1-0.62=0.38. 0.38 is also 38% so Moussa fell asleep for 38% of the trip.
Hopefully this helps you
