URGENT I NEED HELP ANSWERING THESE
I can only answer 5, use my answer to help find 6.
Answer:
The volume is 259,824,773,000
Step-by-step explanation:
r, or radius is half of the diameter. So we are left with (4 * pi (also known as 3.14159)* 3958.5^3)/3
(7.7947432 * 10 ^ 11) / 3 = 779,474,320,000 / 3
Which is equal to 259,824,773,000 as the volume.
I hope this solves 5 and helps you with 6.

A biker travels 8 miles in 10 minutes. Another biker travels 20 miles in 30 minutes. Do these two
rates form a proportion? Explain.
These both rates are not proportional because if 8 mile in 10 minutes and 20 miles in 30 minutes .. So 10 times 3 equals 30 minutes but if we multiply 8 times 3 is equal to 24. So there are not proportional.. I hope this helped
6y + 2 + 3 + 14y
Using the expression shown, add like terms and produce an equivalent expression.
Answer:
20y + 5
Step-by-step explanation:
6y + 2 + 3 + 14y
20y + 2 + 3
20y + 5
Have an amazing day!
PLEASE MARK BRAINLIEST!
Answer:
Added Like Terms: 20y + 5
Equivalent Expression: 12y + 8y + 4 + 1
Explained:
Add like terms. Both 6y and 14y have a variable of y, so they can be added.
6y + 14y = 20y
Next, add the next set of like terms. 2 and 3 both don't have a variable, so you can add em'.
2 + 3 = 5
There are no more like terms to add since 20y has a variable and 5 doesn't, leaving you with the answer 20y + 5.
As for the equivalent expression, I just created another expression that equals 20y + 5.

A runner completed a 26.2-mile marathon in 210 minutes.Estimate the unit rate, in minutes per mile. Round your answer to the nearest tenth of a minute.
Answer:
The unit rate in minutes per miles be 8.02 minutes per miles .
Step-by-step explanation:
Step 1. 26.2 miles/ 210 mins = x miles / 1min
1 * 26.2 / 210 = .12 miles / min
Step 2. 26.2. 0.13
÷210.
210. 1
(The amount miles ran in 1 minute is 0.13 miles.)
Step 3. 26.2/210= .125 miles per minute
210/26.2= 8.02 minutes per mile
Step 4. 1) Cross multiply. (26.2 = 210x)
2) Divide 210 from each side. (26.2/210 = .1247619048 , 210x/210 = x)
3) Round to the nearest 100th. (.12)
4) X=.12
5) .12 miles ran per minute

Min-jun weighs 191 pounds and plans on losing 4.9 pounds each month. Ahab weighs 216 pounds and plans on losing 6.2 pounds per month. If they stick with their plans, how many months will it take Ahab to weigh the same as Min-jun? Write an equation to represent this situation. Use x as the variable. Find the number of months provide an answer accurate to the nearest month
Answer:
if i did my math right it should be 216-(6.2*x) 191-(4.9*x)
Step-by-step explanation:
216-(6.2*x) 191-(4.9*x) and if you go up the line from 0 from the first and second equation you will end up at 8 and 5 so Ahab will have to stick to his plans for 8 months/but if it means how much if he needs to reach near or exactly 191 pounds then it would be only 216-(6.2*x) for the equation and the answer would be 4 months

How can you use random samples of populations to make predictions
Answer:
You can use proportions by settling the ratio from the sample equal to the ratio from the population.
Explanation:
For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.
Answer:
Proportions which would be equal to the ratio from the sample equal to the ratio from the population.
Step-by-step explanation:
I find that Proportions are the easiest way.

0.2a=48. Solve the equation. Pls, thank you!
Answer:
a = 240
Step-by-step explanation:
To solve for a, divide 48 by 0.2:
0.2a = 48
a = 48 / 0.2 = 240
Answer:
Simplifying
0.2a = 48
Solving
0.2a = 48
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '0.2'.
a = 240
Simplifying
a = 240

Answer:
gonna solve fore perimeter and area
P = 12 + 3 + 3 + 9 + 9 + 4 + 4 + 4 = 48cm
P = 48 cm
For area or A it is
A = (12*3) + (4*9) = 72 cm^2
Step-by-step explanation:
use deductive reasoning to determine the missing side lengths, and then solve by splitting the figuring into multiple rectangles
Answer:48 is the perimeter
Step-by-step explanation: 12 + 3 + 3 + 9 + 9 + 4 + 4 + 4
2 3s because there are 2 sides to the top shape and i got the 3rd 4 by using the top 12 and subtracting 8 because there are 4s on both sides of the rectangle that hangs down

Hii.
I'm here to help!
First, we need to work with parenthese. Rembering "Pemdas"
Multiply 7 and 8 to get 56.
56y− 2x/5
To add or subtract expressions, expand them to make their denominators the same. Multiply 56y times 5/5
5x56y
------------ -2x/5
5
Since 5x56y over 5 and 2x over 5 have the same denominator, subtract them by subtracting their numerators.
5 x 56y -2x over 5
Do the multiplications in 5×56y−2x.
280y−2x over 5
7×8y−(2x÷5)
Factor out

hey! This is due at like 11 pm!
Answer:
(x=9)
largest angle= 8x+8(ans=80)
Step-by-step explanation:
first of all we need to find x
we write this as an equation
8x+8+5x-1+5x+11=180
18x+18=180
18x=180-18
18x=162
x=162/18
x=9
Now the question is to find the largest angle
so
we just find the orginal value for all the angles by replacing the x with 9
1. 8x + 8
= 8x9+8
= 80
2. 5x - 1
= 5 x 9 - 1
= 44
3. 5x+11
= 5 x 9 + 11
= 56
Hence the largest angle is 80 ( 8x+8)
Hope this helped.
