Answer:

20 ounces of water

Step-by-step explanation:

Work backwards. David has 18 ounces, which is half of Charlie's. So, Charlie had 18•2=36 ounces. That was 3/5 of Barbara's water, so Barbara had 60 ounces. That is 3/4 of Amanda's water, so Amanda had 80 ounces. To find how much Amanda had left subtract 60 from 80 to get 20.

1) 100N 2) 0.3m/s² 3) 1/2 kg

Step-by-step explanation:

1) F = ma

F = 50×2

F = 100N

2) F = ma

9000 = 30000×a

(9000÷30000) = a

a = 0.3m/s²

3) F = ma

1 = m×2

(1÷2) = m

m = 1/2 kg

Answer:

(2,3)

Step-by-step explanation:

The new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

The point is given as:

(-2,-3)

The rule of reflection across the x-axis is:

(x,y) -> (x,-y)

So, we have:

(-2,-3) -> (-2,3)

Hence, the new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

Answer:

Answer: (286/11) ÷ 2 = 13

Step-by-step explanation:

The quotient of 286 and 11 is given by the equation A = 26

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be represented as x

Now , the value of x = 286

Let the second number be represented as y

The value of y = 11

Let the quotient be represented as A

The value of A is given by the equation ,

A = x/y

Substituting the values in the equation , we get

A = 286/11

The value of A = 26

Therefore , the value of A is 26

Hence , the equation is A = 26

Answer:

24 is the largest fraction fell by 12 to 19

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Keith leaves a 15% for a dinner bill of $25. The amount of tip that Keith leaves will be calculated by multiplying 15% by $25. This will be:

= 15% × $25

= 15/100 × $25

= 0.15 × $25

= $3.75

Keith's total bill will be gotten by adding the dinner bill plus the tip together. This will be:

= $25 + $3.75

= $28.75

Answer:

  Vertex: (-1, 4)

  Maximum: f(-1) = 4

  Increasing: (-∞, -1)

  Decreasing: (-1, ∞)

Step-by-step explanation:

The equation can be written in vertex form by "completing the square."

First factor out the leading coefficient from the x-terms.

  f(x) = -(x² +2x) +3

Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.

  f(x) = -(x² +2x +1) +3 +1

Write in vertex form.

  f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k

You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.

The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)

Maximum: f(-1) = 4
