Answer:

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of<em> 2 ounces lost per second.</em> Now that we know the slope, we can answer the questions

A.  We can get the equation by finding the y int. (below) and writing it as y=-2x+68

B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2x5=10+58= <u><em>68 ounces at the beginning. </em></u>

C. Since we have the formula and the slope, we just need to find when y hits 0. and that is: <em>After 34 seconds.</em>

Step-by-step explanation:

:D hope this helps

Write a 3-digit number that is divisible by both 3 and 4. Explain how you know this number is divisible by 3 and 4.
Alexeev081 [22]

Answer:

let us assume the 3 digit number be 984

To check weather the number is divisible by 3 and 4 then when should know the divisibility rule of 3 and 4.

A number is said to be divisible by 3 when the sum of each digit of the number is divisible by 3. Example 9+8+4 = 21 is divisible by 3 hence the number is divisible by 3.

A number is said to be divisible by 4 when the last two digit is divisible by 4 like 84 is divisible by 4 hence 984 is divisible by 4.

The value to increase is keeping A constant and decreasing the value of B

<h3>What are fractions?</h3>

Fractions are written as a ratio of two integers. For instance a.b is a fraction where a and b are integers.

In the fraction a/b, the numerator is and the denominator is b. If the value of the denominator is decreasing the fraction will increase but if the value of the denominator is increasing the fraction will decrease.

Given the expression A + 2/B, the higher the value of B provided such that that A is constant, the higher the expression. Hence the expression that will cause the value to increase is keeping A constant and decreasing the value of B
