9 - ratio 3:5
10 1/8 + 1/4 = 1/8 + 2/8 = 3/8 of the pizza eaten
so 5/8th of the pizza is left
Answer:
speed = distance/time
Step-by-step explanation:
The faster a sound wave travels, the more distance it will cover in the same period of time. If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s.
Answer: $36.68 or $35.97. Read below.
Step-by-step explanation: You need to multiply the 12 foot by 12 foot and you would get 144 sq feet. Then divide 47 into 144. You will be left with 3.06, and if you need to round, you can round that to 3. Then you need to multiply 3 by $11.99 and you will be left with the cost for the paint, which is $35.97 if you do round to a three, and $36.68 if you do not round the three. So your answer is either $36.68 or $35.97 depending on whether you round or not.
Answer:
1.875
Step-by-step explanation:
Answer:
large tank volume = 6 litres
small tank volume = 3 litres
Step-by-step explanation:
Given that,
The combined volume of 3 large tanks and 2 small tanks is 24 litres.
The combined volume of 2 large tanks and 3 small tanks is 21 litres.
Suppose large tank volume = x
Suppose small tank volume = y
<h2>First Equation </h2>
3x + 2y = 24
<h2>Second Equation </h2>
2x + 3y = 21
Now solve them
3x =24 - 2y
x = (24 -2y) / 3
Put value of x in second equation
2 {(24 -2y) / 3} + 3y = 21
2(8) - 4y/3 +3y = 21
16 - 4y/3 + 3y = 21
3y -4y/3 = 21-16
5y/3 = 5
5y = 15
y = 15/5
y = 3
3x = 24 - 2(3)
3x = 18
x = 6
