Let us assume the number of sandwiches made by Deli = x
Amount of roast beef required for making 1 sandwich = (1/4) pound
Total amount of beef that Marisa started with = 5 pounds
Amount of beef that was left = (3/4) pounds
Then
[(1/4) * x] + (3/4) = 5
(x/4) + (3/4) = 5
(x + 3)/4 = 5
x + 3 = 5 * 4
x + 3 = 20
x = 20 - 3
= 17
So we can see from the above deduction that 17 Deli sandwiches was made by Marisa. I hope the procedure is clear enough for you to understand.
Answer: 5hrs = 200miles.
if you divided 120 by 3 you will get 40 thats how many miles it in 1 hour.
Step-by-step explanation:
1 hour = 40
2 hours = 80
3 hours = 120
4 hours = 160
5 hours = 200
the equation is increasing by 40 per hour

Answer:
40 times
Step-by-step explanation:
It is given that,
The aperture of Keck telescope, d₁ = 10 m
The aperture of the amateur is 25 cm or, d₂ = 0.25 m
Gathered light is directly proportional to the area of the mirrors as :

r is radius, r = d/2 (d=diameter of the mirror)

It is directly proportional to the diameter of the mirrors.
On taking ratios of the area of both mirrors, we can get the ratio of light gathered.
So,

It means that Keck telescope will gather 40 times light than amateur telescope.
