Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting
kodGreya [7K]

Josiah and Chana travel at constant and different speeds.

  • The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

<h3>How can the what the the point <em>F </em>represent be known?</h3>

Josiah's head start = 10 meters from the start

Josiah's speed = 2 m/s

Chana's speed = 3 m/s

Expressing the distance traveled as an equation, we have;

D = d + s × t

Where;

D = The distance covered

d = The distance from the starting line the runner starts

s = The speed of the runner

t = The time spent running

For Josiah, we have;

D = 10 + 2•t (line <em>a</em>)

For Chana, we have;

D = 0 + 3•t = 3•t (line <em>b</em>)

The above equations are straight line equations.

The point <em>F </em>is on line <em>a</em>, which shows Josiah distance after 25 seconds which is 60 meters. The corresponding point on line <em>b</em>, Chana's distance after 25 minutes is 75 meters.

Therefore;

  • The point <em>F </em>indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

How much total wrapping paper does it take to wrap two gifts: one with the dimensions of 6 cm by 10 cm by 9.5 cm and the other w
zhuklara [117]

Answer:

gift 1:

424 cm^2

570 cm^3

gift 2:

1420.5 cm^2

3622.5 cm^3

Step-by-step explanation:

We have to calculate the surface area of these gifts in order to know the amount of wrapping paper.

The formula for the surface area is:

A = 2*ab + 2*ac + 2*bc

Gift 1:

A = 2*6*10 + 2*6*9.5 + 2*10*9.5

A = 424 cm^2

That means that gift 1 needs 424 cm^2 of wrapping paper

Gift 2:

A = 2*14*17.25 + 2*14*15 + 2*17.25*15

A = 1420.5 cm^2

That means that gift 2 needs 1420.5 cm^2 of wrapping paper

Now, to calculate the cubic centimeters of packaging peanuts, we calculate the volume, the volume has as formula:

V = a*b*c  

Gift 1:

V = 6*10*9.5  

V = 570 cm^3

This means that gift 1 needs 570 cm^3 of packaging peanuts

Gift 2:

V = 14*17.25*15  

V = 3622.5 cm^3

That means that gift 2 needs 3622.5 cm^3 of packaging peanuts

Omg this is too hard, which is this one?
Juli2301 [7.4K]
Hi there!
So, to start you have to convert cups into ounces.
1 cup is 8 fluid ounces, so 3 cups are 8*3 which are 24 fluid ounces.
So, if she filled x amount of 2-ounce containers, then it would be 24/2 which are 12 containers that are full.

The answer is C) 12.


Hope it helps!
