We are given

Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).

so, time is

T=0.25\sqrt{60} =\frac{1}{4} \sqrt{60}

we have to approximate it's value

First approximation set:

we know that

49

we can take sqrt all the sides

\sqrt{49}

we can simplify it

7

Divide all sides by 4

\frac{7}{4}< \frac{1}{4} \sqrt{60}

Second approximation set:

7.7

Divide all sides by 4

\frac{7.7}{4}

1.925

Third approximation set:

7.74

Divide all sides by 4

\frac{7.74}{4}

1.935

so, we get

t=1.94seconds......Answer

Svetach [21]
Think of this situation as a system of equations.

let y be the price of hotdogs
let x be the price of hamburgers

5y + 2x = 8
2y + 5x = 9.50

now use your solution method of choice
substitution, elimination, matrices, etc

Dennis_Churaev [7]

Answer:

Circle

Step-by-step explanation:

When a plane passes through a 3-dimensional figure to create a cross section that is parallel to the base, the resulting 2-dimensional shape of the cross section is the same as the shape of the base.

The base of an ice cream cone is a circle, therefore the answer is circle
