Answer:
1.958 * 10^-5 seconds or 0.00001958 seconds.
Step-by-step explanation:
3740 = 3.74 * 10^3 in scientific notation.
Time = distance / speed.
= 3. 74 * 10^3 / 1.91 * 10^8
= 1.958 * 10^-5 seconds.
Answer:
3 gallons of paint
Step-by-step explanation:
Various data is missing, but I think it can be solved with the following assumptions:
The first thing is to assume that 12 gallons was the exact amount needed for the two rooms.
If so, we can say the following where x is the size of the smallest room:
Room 1: It is 2 * x and needs 3 coats of paint, so there would be 6 * x left
Room 2: is x and uses 2 coats of paint therefore 2 * x
The paint sum would be as follows:
6 * x + 2 * x = 8 * x
8 * x = 12
x = 12/8 = 3/2
So:
Room 1: 6 * 3/2 = 9, 9 gallons of paint needed
Room 2: 2 * 3/2 = 3, 3 gallons of paint needed
Room two is the unpainted one so 3 gallons of paint was returned.
Answer:
the forth
Step-by-step explanation:
you know that hipotenusa is the longest side in a rectangle triangle and its formula is H=
for each group of number you apply the formula you will see that 13 and 84 do not have 85 as hipotenusa
210 because 3 times 70 is 210. so 210 cm
