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 2 ounces lost per second. 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= 68 ounces at the beginning.

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

Step-by-step explanation:

A cube is painted so that one side is blue, two sides are red, and three sides are green. How many different such cubes can be p

Angelina_Jolie [31]

Answer:

So there are 3 distinct cubes.

Step-by-step explanation:

There are total six sides of the cube.

if we observe the given data and fix the sides of the cube by the color

So,

let suppose,

Blue color is painted on the top side of the cube

Now, we have left 5 sides

as per the information 2 sides are painted by Red color

let suppose,

1 Red color is painted on bottom side And 1 is on side

Now, we have left 3 sides

And 3 sides are green as per the given information.

1 green color painted on the adjacent side of the red side

1 green side is opposite of red side.

and 1 opposite of green side.

Now all side are colored and if we observe the above scenario

All other possibilities can be rotated to one of these.

So there are 3 distinct cubes.

Simplify the expression -7/9 - 5/10

sattari [20]

We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.

We can generate equivalent fractions by multiplying both numerator and denominator by the same number.

So, we have

$-\dfrac{7}{9} = -\dfrac{7\cdot 10}{9\cdot 10} = -\dfrac{70}{90}$

Similarly, we have

$-\dfrac{5}{10} = -\dfrac{5\cdot 9}{10\cdot 9} = -\dfrac{45}{90}$

Now we can sum the fractions:

$-\dfrac{7}{9}-\dfrac{5}{10} = -\dfrac{70}{90}-\dfrac{45}{90} = \dfrac{-70-45}{90} = -\dfrac{115}{90} = -\dfrac{23}{18}$

(I'll give brainliest and a free thanks) Apply the distributive property to produce an expression equivalent to `5(8+q)`.

iris [78.8K]

Answer:

40+5q

Step-by-step explanation:

Distributive property is multiplying each number inside the parentheses by the number outside the parentheses.

For example: a(b+c) would be ab+ac

Knowing that all you have to do now is multiply:

5x8=40

5xq=5q

Put them together and you get 40+5q!

I hope this helps, and have a great day! :)

You find a sales receipt from a store that shows the total price as $40, and the total amount paid including sales tax as $42.

kenny6666 [7]

42 = 40(x-1) + 40

x-1 will be equal to the sales tax rate in this equation.
