5C. Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?

Answers

Answer 1

Answer:

20 ounces

Step-by-step explanation:

For this type of problem it is best to work backwards.

If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda still have. So, 80- 60(The amount of water she gave to Barbara)=20.

which number is a zero of f(x) = 2x (x + 7) ( x-4)​

Answers

Answer:

0, -7, 4

Step-by-step explanation:

Zeros of a function are values that make the function = 0

So, f(x) = 2x(x + 7)(x - 4) = 0

                x = 0 or x + 7= 0  or x - 4 = 0

                                   x = -7           x = 4

Note:  If you were to graph f(x), the graph would intercept the x-axis at 0, -7, and 4

Vo, 3)
(1.15

Answers

Answer:

C, f(x) = 3(2)^x

Step-by-step explanation:

Since the y-intercept is 3, the function will have 3 multiplying by some number to the power of x.

As x increases by 1, we notice that y multiplies by 2 every time.

This leads us to believe that the equation is 3 * 2^x

The exponential function represented by the graph is:

[tex]f(x) = 3(2)^x[/tex]

What is an exponential function?

It is modeled by:

[tex]y = ab^x[/tex]

In which:

a is the initial value, that is, the value of y when x = 0.b is the rate of change.

In the graph, there is point (0,3), hence a = 3, and it also has point (1,6), hence:

[tex]6 = 3b[/tex]

[tex]b = 2[/tex]

Thus, the equation is:

[tex]f(x) = 3(2)^x[/tex]

The measure of one interior angle of a parallelogram is 50 degrees more than 4 times the measure of another angle
The measure of the smaller interior angle is
and the measure of the larger interior angle is?

Answers

Answer:

smaller ∡ = 26°

larger ∡ = 154°

Step-by-step explanation:

opposite angles are congruent

adjacent angles are supplementary

in this problem, the angles are supplementary

'x' = measure of smaller angle

x + 50 + 4x = 180

5x = 130

x = 26

The given information and the relationship between the angles of a

parallelogram can be used to find the interior angles.

The measure of the smaller angle is 26°The measure of the larger angle is 154°

Reasons:

A property of a parallelogram is that the diagonally opposite angles are

equal, and the adjacent angles are supplementary.

Therefore, two of the four interior angles of a parallelogram are equal.

Let x and y represent the two angles of different measure in the

parallelogram

y = 4·x + 50°

y + x = 180°

Which gives;

y = 180° - x

Therefore;

180° - x = 4·x + 50°

180° - 50° = 4·x + x

130° = 5·x

x = 130° ÷ 5 = 26°

x = 26°

y = 4 × 26° + 50° = 154°

y = 154°

Therefore;

The measure of the smaller interior angle, x = 26°The measure of the larger interior angle, y = 154°
