14. A satellite orbits 22, 300 miles above the equator. It completes one revolution in 24 hours. Assume that the radius of the Earth is 3, 960 miles. How far will the satellite travel in one day?
Answers
Answer:
Displacement = 0 mi
Distance = 164,996.45 mi
Step-by-step explanation:
In this case, the displacement will be zero because the satellite goes back to its starting point after one day. If there is no distance traveled between the starting point and the ending point, then the Displacement will be zero.
When it comes to the distance, we will need to calculate the perimeter of the circle the satellite describes when making one whole turn around the earth.
The perimeter of a circle is given by the equation:
[tex]p=2\pi r[/tex]
so we need to start by finding what the radius of the circle is. This radius if found by adding the radius of the earth and the distance above the equation the satellite is located at, so we get that:
[tex]r=r_{earth}+h[/tex]
where h is the height of the satellite, so the radius of the circle is:
[tex]r=22,300mi + 3,960 mi[/tex]
so
r=26,260 mi
so now we can use the perimeter equation to get:
[tex]p=2\pi r[/tex]
[tex]p=2\pi (26,260)[/tex]
So the distance traveled by the satellite in one day will be:
P=164,996.45 mi.

Johny and Rahul divided the benefit of the business in the ratio 7:9. If
Rahul got 4878 rupees as benefit did Johny get?
Answers
Answer:
Step-by-step explanation:
7:9 = x:4878
4878/9 times 7
3794 would be your answer
Answer:
3,794 rupees
Step-by-step explanation:
Johny got 7 parts of the benefit while Rahul got 9. This can be represented as a fraction: 7/9
To solve this problem, we can use cross multiplication, where x represents the amount of rupees Johny got:
[tex]\frac{7}{9}[/tex] = [tex]\frac{x}{4878}[/tex]
Multiply 7 by 4,878: 34,146
Multiply 9 by x: 9x
Now the equation looks like this:
9x = 34,146
Divide both sides of the equation by 9 to isolate the x:
9x/9 = 34,146/9
x = 3,794
Johny got 3,794 rupees.
Container A and container B have leaks. Container A has 800 ml of water, and is
leaking 6 ml per minute. Container B has 1000 ml, and is leaking 10 ml per minute.
How many minutes will it take for the two containers to have the same amount of
water?
**Write an equation to represent the situation (first blank). Use the variable m, for
minutes.
**Then solve for m (second blank).
**Finally, use your solution to determine the water level at that time (third blank).
The equation
can represent this situation. It will take
minutes for the two containers to have the same amount of water. At this time,
both containers will have ml left.
Answers
Answer:
a) 50 minutes
b) The water level at 50 minutes for Container A and B would be 500ml
Step-by-step explanation:
a) Let number of minutes at which both containers leak be represented by m.
Container A has 800 ml of water, and is leaking 6 ml per minute.
800ml - 6ml × m
800 - 6m
Container B has 1000 ml, and is leaking 10 ml per minute.
1000ml - 10ml × m
1000 - 10m
How many minutes will it take for the two containers to have the same amount of water?
Container A = Container B
800 - 6m = 1000 - 10m
Collect like terms
-6m + 10m = 1000 - 800
4m = 200
m = 200/4
m = 50 minutes
It will take 50 minutes for the two containers to have the same amount of water.
b) Finally, use your solution to determine the water level at that time.
Since m = 50 minutes
Container A = Container B
800 - 6m = 1000 - 10m
800 - 6 × 50 = 1000 - 10 × 50
800 - 300 = 1000 - 500
500 ml = 500 ml
Therefore, the water level at 50 minutes is 500 ml

Two eighth-grade classes are selling chocolate bars to raise money for an end-of-year field trip. One class is selling chocolate bars for $3.00 each and has already raised $275.00. The other class is selling chocolate bars for $3.50 each and has already raised $250.00. Which equation can be used to calculate c, the number of additional chocolate bars each class needs to sell, so that the total amount raised is the same for both classes?
Answers
Answer:
Step-by-step explanation:
you add both $275.00 and $250.00 ($525.00) then and $3.00 and $3.50 ($6.50) then divide $525.00 by $6.50 and then you answer would be $88.00
so c = $88.00
Answer:
3.50c + 250.00 = 3.00c + 275.00

of jackfruits in the three baskets.

Answers
Answer:
156 jackfruits
Step-by-step explanation:
Let there are 6x jackfruit in baseket P, 2x in basket Q and 5x in basket R.
The total number of jackfruit in basket P is 48 more than the number of jackfruit in basket Q. ATQ,
6x = 48 + 2x
Solving for x.
6x - 2x = 48
4x = 48
x = 12
Jackfruits in basket P = 6x = 6(12) = 72
Jackfruits in basket Q = 2x = 2(12) = 24
Jackfruits in basket R = 5x = 5(12) = 60
Total no of jackfruits = 72 + 24 + 60
= 156
So, there are 156 jackfruits in the three baskets.
