Mathematics

ankoles [38]3 years ago

3 0

Answer: A. There were 500 liters in the tank when the leak started, and it is decreasing by 9 liters per minute.

Step-by-step explanation:

This equation is in the form; y =mx + c.

c in this equation is the value of y when x is at 0.

c in the above formula is 500 which means that the number of litres (y) at zero minutes(x) is 500 litres.

m is the rate of change as a result of a change in x.

m in this equation is -9 which means that the water is reducing by 9 litres every minute (x).

How do u get this?? I know the answer but then I don't know why they shuld divide by 2 I will mark the person who explains wit p

Greeley [361]

Answer:

10.89

Step-by-step explanation:

Circle:

C = TTD

C = TT(6.6)

C = 20.73451151

C = 20.73

Triangle:

A = bh/2

A = 6.6(3.3)/2 6.6/2=3.3

A = 21.78/2

A = 10.89

Shaded Region = 10.89

Solve the following equation for d: D — =7 5

SIZIF [17.4K]

Answer: x = 35

Explanation: In this problem, notice that D is being divided by 5,

so to get D by itself, we need to multiply both sides of the equation by 5.

Notice that on the left side, the 5 and 5 cancel

each other out, so we are just left with D.

On the right side, we have (7)(5) which is 35.

So x = 35.

Finally, remember that we can check our answer

by plugging a 35 back into the original equation.

So we have $\frac{(35)}{5} = 7$ .

Since this is a true statement, we know that our answer is correct, x = 35.

Do u know what a rotio table or a in and out box if u do that how I have to solve it and I need to know the rule

SOVA2 [1]

Okay so an in and out box is a box is basically a tale. Do you have a rule ? so if you have a rule..(which i do not know) lets say the rule is +2. lets also say that the IN says 4. Then what would be the out ? The out would be whatever 4+2 is. So basically the "out" is the outcome.
