The weight of an object above the surface of the earth varies inversely with the square of its distance to the center of the earth. If an object weighs 50 pounds when it is 3960 miles from the center of the earth, what would its weight be when it is 3975 miles from the center of the earth?
Answers
Answer:
W = K m / R^2 expresses weight of ojject
W2 / W1 = (R1 / R2)^2 ratio of W2 to W1
W2 = W1 * (3960 / 3975)^2 = 50 * .992 = 49.62 lbs

On a trip, a student drove 42 miles per hour for 3 hours and then drove 26 miles per hour for 5 hours. What is the student’s average rate of speed, in miles per hour, for the whole trip? *
1. 126 MPH
2. 32 MPH
3. 130 MPH
4. 8.5 MPH
Answers
Answer:
34 mph
Step-by-step explanation:
Average speed = total distance / total time
Total distance = ( 40 × 2 + 30 × 3 )
= 170 miles
Total time = 5 h
So, avg speed = 170/5 = 34 mph

Step-by-step explanation:
Answer:
3 1/3 or 10 / 3
Step-by-step explanation:
7 1/2 divided by 2 1/4 =
Multiply 7 by 2.
7 x 2 = 14
Add 1 to 14 because of the 1 in 1/2.
14 + 1 = 15
7 1/2 turns into 15 / 2.
Do the same for 2 1/4.
Multiply 2 by 4.
2 x 4 = 8
Add 1 to 8 because of the 1 in 1/4.
8 + 1 = 9
2 1/4 turns into 9 / 4.
15 / 2 divided by 9 / 4
KEEP CHANGE FLIP!!
15 / 2 x 4 / 9
15 x 4 = 60 & 2 x 9 = 18
15 / 2 x 4 / 9 = 60 / 18
Let's simplify 60 / 18 by dividing by the greatest common factor; 6.
60 / 6 = 10 & 18 / 6 = 3
10 / 3 = 3 1/3
Hope this helped!

Answer:
the length would be 3ft and the width would be 2ft
Step-by-step explanation:
this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer
Answer:
LENGTH - 3cm / WIDTH - 2cm
Step-by-step explanation:
Well first off, you would use the scale: 1 cm = 4 ft
With 12, you divide by 4. 12 ÷ 4 = 3
With 8, you also divide by 4. 8 ÷ 4 = 2
So, it would be 3 cm long and 2 cm wide.

The fraction a/b is in simplest terms and equal to the following:((2020^3)-1)/((2021^3)+1) . What is a + b?
Answers
Consider the expression
[tex]\dfrac{x^3-1}{(x+1)^3+1}[/tex]
Factorize the numerator and denominator a difference/sum of cubes:
[tex]\dfrac{(x-1)(x^2+x+1)}{((x+1)+1)((x+1)^2-(x+1)+1)}[/tex]
Expand the denominator:
[tex]\dfrac{(x-1)(x^2+x+1)}{(x+2)((x^2+2x+1)-(x+1)+1)}=\dfrac{(x-1)(x^2+x+1)}{(x+2)(x^2+x+1)}=\dfrac{x-1}{x+2}[/tex]
since x = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of x ² + x + 1. This leaves us with
[tex]\dfrac{2020^3-1}{2021^3+1} = \dfrac{2020-1}{2020+2} = \dfrac{2019}{2022}=\dfrac{673}{674}=\dfrac ab[/tex]
so that a + b = 673 + 674 = 1347.

Answer:

Step-by-step explanation:
I like to let a graphing calculator or spreadsheet do repetitive calculations. It is well worth the few minutes it takes to learn how to enter a formula into any of the available free spreadsheet programs. The Desmos graphing calculator is amazing in its versatility and usefulness.
There are a couple of things that can help make it easier to construct a table of values.
1) recognize the axis of symmetry for this quadratic is ...
x = -b/(2a) = -25/(2(-5)) = 2.5
So, choosing numbers either side of t=2.5 will cut your work in half.
h(2) = h(3)
h(1) = h(4) . . . for example
2) use Horner form to make manual evaluation easier.
h = (-5t +25)t +2 or = (5 -t)(5t) +2

The rectangular screen on a laptop has an area of 375 cm ^ 2 Its width is 10 cm less than its length. What are the dimensions of the screen?
Answers
Answer:
lenght = 25 cm
widht = 15 cm
Step-by-step explanation:
Dimensions of the screen
375 = (l - 10) × l
375 = l² - 10l
l² - 10l -375 = 0
(l + 15)(l -25)
l = -15 or l = 25
