coach currans team has won 5 times and lost 2 times he hopes that his team can keep this same ratio of wins to losses.
if the team has 10 losses how many wins would they need to keep the record? complete the table
wins: 5 ?
losses: 2 10
wins: 5 ?
losses: 2 10
To find out the number of wins needed to maintain the same ratio, we can create a proportion:
wins/losses = 5/2 = x/10
Solving for x:
2x = 5 * 10
2x = 50
x = 25
So, the team would need to have 25 wins to maintain the 5:2 ratio with 10 losses.
Therefore, the table is:
wins: 5 25
losses: 2 10
because of the way that hummingbirds move their wings they can fly forward backward and upside down.
while in flight, some hummingbirds can flap their wings about 500 times in 10 seconds.
at this speed how many times might a hummingbird flap its wings in 60 seconds? complete the table
flaps: 500 ?
seconds: 10 60
flaps: 500 ?
seconds: 10 60
To calculate how many times a hummingbird might flap its wings in 60 seconds based on flapping 500 times in 10 seconds, we can create a proportion:
flaps/seconds = 500/10 = x/60
Solving for x:
10x = 500 * 60
10x = 30000
x = 3000
Therefore, a hummingbird might flap its wings about 3000 times in 60 seconds.
The completed table is:
flaps: 500 3000
seconds: 10 60
amalia makes trays by gluing tiles on pieces of wood. the picture shows one of her tile designs. amalia wants to know how many black and white tiles she needs to make different numbers of trays.
enter the number of tiles needed to make 2 trays. multiply each quantity by 2
the tray has 9 white tiles with 4 black tiles in each of the corners.
To calculate the total number of tiles needed to make 2 trays, we can first find the number of tiles needed for one tray and then multiply by 2:
Each tray has:
- 9 white tiles
- 4 black tiles for each tray in the corners
So, the total number of tiles needed for one tray is:
9 white tiles + 4 black tiles = 13 tiles
To make 2 trays, you would need:
2 trays * 13 tiles/tray = 26 tiles
Therefore, you would need 26 tiles to make 2 trays.

the tray has 9 white tiles with 4 black tiles in each of the corners.
To calculate the total number of black and white tiles needed to make 2 trays, we first find the number of tiles needed for one tray:
Each tray has:
- 9 white tiles
- 4 black tiles in each of the corners
Therefore, for one tray, we need 9 white tiles + 4 black tiles = 13 tiles.
To make 2 trays:
- White tiles needed for 2 trays = 2 trays * 9 white tiles/tray = 18 white tiles
- Black tiles needed for 2 trays = 2 trays * 4 black tiles/tray = 8 black tiles
Therefore, to make 2 trays, you need:
- 18 white tiles
- 8 black tiles
Completing the table:
