John can eat a sixth of a pizza in two minutes. It takes 3 minutes for Billy to eat one quarter of the same pizza. If John and Billy start eating one pizza each, who will finish first?

Answers

Answer 1

Answer:

They both will finish at the same time.

Step-by-step explanation:

John can finish [tex]\frac{1}{6}[/tex] of the pizza in 2 minutes.

2 minutes ---> [tex]\frac{1}{6}[/tex]

1 minutes ---> 0.833

Billy can finish [tex]\frac{1}{4}[/tex] of the pizza in 3 minutes.

3 minutes ---> 0.25

1 minutes ---> 0.0833

Therefore, they both shall finish at the same time.

Answer 2

Answer:

It takes John and Billy 12 minutes, and they will finish at the same time.

Step-by-step explanation:

In one pizza, there are 6 sixths and John will take .

2 × 6 = 12 minutes to finish one pizza

In one pizza, there are 4 quarters and Billy will take .

3 × 4 = 12 minutes to finish one pizza.

It takes each one of them 12 minutes and they will finish at the same time.

chef ollie has a community garden.she uses 2/6 of the farmland to grow beets and 1/6 of the farmland to grow kale. how much of the farmland is left? color in the grids to show how chef ollie might use the rest of her community garden. Write an equation to match.

Answers

Answer:

1/2 of farm land left.

Step-by-step explanation:

  Ok so we know that Chef Ollie has a community garden. And that she uses [tex]\frac{2}{6}[/tex] of the farmland to grow beets. The denominator 6 lets you know immediately that the land is divided into equal 6 pieces. We also know that Chef Ollie uses another [tex]\frac{1}{6}[/tex] of the farmland to grow kale.

  Because the we need to find out how much land Chef Ollie has left, we need to subtract the amount she used from the whole. Before we can do that we must add up the total amount of used land, and since the denominators are the same we can directly add and subtract with having to change the denominator.

Step 1: Write down important numbers.

[tex]\frac{2}{6}[/tex], [tex]\frac{1}{6}[/tex],

Step 2: Add those numbers together.

[tex]\frac{2}{6} + \frac{1}{6} = \frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex]

Step 3: Write an expression/equation.

[tex]\frac{6}{6} - \frac{3}{6} \\or\\1 - \frac{1}{2}[/tex]

Step 4: Solve

=    [tex]\frac{3}{6}\\or\\\frac{1}{2}[/tex]

(can be written both ways)

  And you get your answer: After Chef Ollie has used [tex]\frac{2}{6}[/tex] to grow beets and [tex]\frac{1}{6}[/tex] to grow kale, she has [tex]\frac{1}{2}[/tex] of her farmland left untouched.

  To represent this you could draw a circle divided in 6 pieces and shade 3 of them, or simply draw a circle and shade half. As well as drawing a rectangle and dividing it into 6 pieces, shading 3, or draw a rectangle, and shade half.

C) y=1/2x+6 2x+5=y

the answer is A because the slopes are the same but the Y intercept are in opposite sides, which means they will never intersect - giving us no solutions.

Suppose you have a dart board hanging on a wall If you throw a dart randomly at the wall, and assuming your dart lands somewhere on the wall , what is the probability that your dart will land a) in region X b) in region c) in region Z

Answers

Probabilities are used to determine the chances of events

The probability of landing in region X is 0.087The probability of landing in region Y is 0.109The probability of landing in region Z is 0.153

The probability of landing in region X

The area of region X is:

[tex]A = \pi r^2[/tex]

So, we have:

[tex]X = 3.14 * 4^2[/tex]

[tex]X = 50.24[/tex]

The area of the dart is:

[tex]A = Length * Width[/tex]

[tex]A = 24 * 24[/tex]

[tex]A = 576[/tex]

The probability of landing in region X is then calculated as:

[tex]P(X) = 50.24/576[/tex]

[tex]P(X) = 0.087[/tex]

The probability of landing in region Y

The area of region Y is:

[tex]A = \pi R^2 - \pi r^2[/tex]

So, we have:

[tex]Y = 3.14 * 6^2 -3.14 *4^2[/tex]

[tex]Y = 62.8[/tex]

The probability of landing in region Y is then calculated as:

[tex]P(Y) =62.8/576[/tex]

[tex]P(Y) =0.109[/tex]

The probability of landing in region Z

The area of region Z is:

[tex]A = \pi R^2 - \pi r^2[/tex]

So, we have:

[tex]Z = 3.14 * 8^2 -3.14 *6^2[/tex]

[tex]Z = 87.92[/tex]

The probability of landing in region Z is then calculated as:

[tex]P(Z) = 87.92/576[/tex]

[tex]P(Z) = 0.153[/tex]

Hence, the probability of landing in region Z is 0.153

Therefore, volume = [tex]\pi[/tex] x 5² x 3

which of the following best describes the graph shown below

Answers

Since the graph of a linear function is a straight line, so the first option is not correct.
The given graph is of a function because for a particular value of y, there is a fixed value of 'x'.
Also, since there are two different values of x having same value for y, so the function is not one-to-one. For example, If y = f(x) is the function, then f(1.5) = f(-1) = 3.
Therefore, the graph represents a function, but it is not one-to-one.
Thus, the correct option is (A) THE ANSWER Is A

Answer:

A

Step-by-step explanation:

In the graph shown, no two y values share an x value. If you were to pass a vertical line through it at any point, it would only intersect it once, which makes it a function.

Many x values in the graph share y values; if you were to pass a horizontal line through it, it would intersect it more than once at certain points, which makes it NOT one-to-one.

This means that the answer is A: This is the graph of a function, but it's not one-to-one.

The graphs below have the same shape what is the equation of the red graph

Answers

Answer: D. 5 - x^4

Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.
