No. The closest equivalent to 3/5 is 6/10 and the closest equivalent to 6/12 is 3/6.

Answer:

Step-by-step explanation:

We can simplify 6/12 by dividing the top and bottom by 6

6/12 =1/2

3/5 and 1/2

The common denominator is 10

3/5 *2/2 =6/10

1/2*5/5 = 5/10

They are not equal

Matt buys a new fish tank. The fish tank is in the shape of a cuboid. The diagram shows water in the tank. 30 cm 30 cm 100 cm Ma

lyudmila [28]

Answer: Yes, but only if he houses 37, 38, 39, or 40 fish

Anything larger than 40 and he'll need more room.

==========================================================

Explanation:

The tank is 30 cm by 30 cm by 100 cm. The volume is 30*30*100 = 90,000 cm^3 which is shorthand for "cubic centimeters".

We're told that 1000 cm^3 = 1 liter, which means the 90,000 cm^3 converts to (90,000)/(1000) = 90 liters.

The fish tank is 90 liters.

Since 1 gallon = 4.5 liters, this means the 90 liter tank converts to 90/(4.5) = 20 gallons

----------------------------

Your teacher mentions "He can keep 2 small fish for every 1 gallon".

Since the tank is 20 gallons, that means he can keep 20*2 = 40 fish. This value is larger than 36, so Matt is correct to a point. If Matt is thinking 37, 38, 39, or 40 fish then he would be correct. If Matt is wanting more than 40 fish, then he'll need a bigger tank.

In short, he can't have any number over 36 and can only have 4 specific values (the four values mentioned earlier).

So technically, Matt is correct, but strong clarification is needed.

When a ferry boat is on open water, it travels at a constant speed. A ferry boat traveled 4 miles in 10 minutes. Complete the eq

ozzi

Answer:

The equation is: $y=0.4x$

The relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line, as shown in attached graph.

Step-by-step explanation:

As boat travels at constant speed.

So, if ferry boat travels 4 miles in 10 minutes. It means it would complete 24 miles in one hour.

And in 1 minute, 0.4 miles will be completed.

So, the equation becomes

$y=0.4x$

As the slope intercept form is $y=mx+c$

So, $m=0.4$ is the slope

The relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.

The graph is also attached which indicates that relationship between the time in minutes, t, and the distance traveled in miles, d is a straight line i.e. linear.
