Ballio is 12 4/5 years old. Bill is 1 1/6 years older than Ballio and Jane is 1 1/3 years older than Bill. How old is Jane?

Answers

Answer:

15 3/10 years

Step-by-step explanation:

Ballio age = 12 4/5

Bill's age = Ballio's age + 1 1/6

Bills age = 12 4/5 + 1 1/6 = 64/5 + 7/6 = (384 + 35) / 30 = 419 / 30 = 13 29/30

Jane's age :

13 29/30 + 1 1/3

419 / 30 + 4 /3 = (419 + 40) / 30 = 459 / 30 = 15 9/30

15 9/30 = 15 3/10 years

2 * 3.20 = $6.40

1 * 8.79 = $8.79

we add up all these numbers, 28.14

Answer:

A) The total of supplies Jesse needs is $28.14

B) He would still need $8.14 to complete the birdhouse

Step-by-step explanation:

Jess has $20

1 piece of strong board = $12.95

2 boards = $3.20 each (2 x 3.20 = $6.40 total)

10 foot post = $8.79

$12.95 + $6.40 + $8.79 = $28.14

$20 - $28.14 = -$8.14

The total price $28.14

He would need $8.14 more

At 4 PM, the level of the water in the lake was 10 feet. At 8 PM, the level of the water was 2 feet. Determine the constant rate of change of the water.

Answers

Answer:

[tex]-4\ \text{feet/hour}[/tex]

Step-by-step explanation:

Level of water at 4 PM is 10 feet.

Level of water at 8 PM is 2 feet.

Time duration in which water level is measured is [tex]8-4=4\ \text{hours}[/tex]

The change of the level of water in the given time duration is [tex]2-10=-8\ \text{feet}[/tex]

The rate of change would be

[tex]R=\dfrac{-8}{4}=-4\ \text{feet/hour}[/tex]

The constant rate of change of the water is [tex]-4\ \text{feet/hour}[/tex].

The minus sign indicates that the water level is reducing.

Answers

Answer:

Step-by-step explanation:

f(x) = 1 - x²

g(x) = [tex]\sqrt{11-4x}[/tex]

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]

[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]

             = [tex]\frac{1-1}{\sqrt{15}}[/tex]

             = 0

(g + f)(x) = g(x) + f(x)

             = [tex]\sqrt{11-4x}+1-x^2[/tex]

(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]

             = [tex]\sqrt{3}-3[/tex]

(g - f)(x) = g(x) - f(x)

            = [tex]\sqrt{11-4x}-(1-x^2)[/tex]

            = [tex]\sqrt{11-4x}-1+x^2[/tex]

(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]

             = [tex]\sqrt{15}[/tex]

(g . f)(x) = g(x) × f(x)

            = [tex](\sqrt{11-4x})(1-x^2)[/tex]

(g . f)(2) = [tex](\sqrt{11-4(2)})(1-(2)^2)[/tex]

This graph represents a linear function.

Enter an equation in the form y = mx + b that represents the function described by the graph.

Answers

Answer:

y=2x-2

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the line y=mx+b we need two points. I choose (0,-2) and (1,0)

Since y=mx+b where m=slope and b=y intercept (value of y when x=0)

We have the point (0,-2) so we know b=-2

Now we find the slope which is defined as

m=(y2-y1)/(x2-x1), in this case

m=(0-(-2))/(1-0)

m=2, so the line is

y=2x-2

You and your friend go to an amusement park. You buy t tickets and spend $8 on food.Your friend buys t tickets and spends $12 on food. Is it possible that you and your friend spent the same amount at the amusement park.

Answers

Answer:

In the case of 4 tickets it can be possible

Step-by-step explanation:

Let us assume the number of tickets be t

Now as per the question the equations would be

For you  = t + $8

For your friend = t + $12

In the case when you both spend the same amount so the above equations would be equivalent to each other

t + $8 = t + $12

So here the tickets would be 4 so this is possible that you both spend the same amounts

A ball is thrown from an initial height of 5 feet with an initial velocity of 32 ft/s. The height h (in feet) after t seconds is represented by the function h=-16t^2+32t+5. Find the maximum height of the ball.

Answers

Find the derivative and set equal to 0 (the speed of the object is zero when the object is at max height and s hanging direction)
-32t+32=0

So the object hits a max at t=1

Plug that into original equation and get h=21 feet

Answers

Answer:

A) Leo comió más, ya que comió 1/2 de la pizza.

B) Joel y Evelio comieron menos, ya que comieron 1/8 de la pizza.

C) Asimismo, Joel y Evelio comieron igual, ya que cada uno comió 1/8 de la pizza.

D) En total, entre todos comieron una pizza.

Step-by-step explanation:

Dado que cuatro amigos compraron una pizza, de la cual Leo se comió 1/2, Adán 1/4, Joel 1/8 y Evelio se comió lo que sobró, para determinar quién comió más, quién comió menos, quiénes comieron igual y cuántas pizzas se comieron en total se deben realizar los siguientes cálculos:

1/2 + 1/4 + 1/8 + X = 1

4/8 + 2/8 + 1/8 + X = 1

7/8 + X = 1

X = 1 - 7/8

X = 1/8
