Answer:

Step-by-step explanation:

since 3 * 15 = 45, we know that we have to multiply 5 by 15. so the ratio would be 45:75. I hope this helps!

Answer

45:75

Step-by-step explanation:

The original ratio tells you there are 3 boys to 5 players total. If you divide the given amount of boys (45) by the original (3) then you get 15 (this is what you would use to find the players) 15 x 5= 75, so your answer is 45 boys to 75 players.

You are choosing 4 of your 7 trophies and arranging them in a row on a shelfIn how many different ways can you choose and arrang

erastova [34]

The formula to find how many different ways are there to choose a subgroup of r things from a group of n things is

$\frac{n!}{(n-r)!}$

Here, you have 7 trophies and you want to choose 4 of them, so you have

$\frac{7!}{(7-4)!}\text{ = }\frac{5040}{6}=840$

So there are 840 ways to choose your 4 trophies out of the 7 you have.

Answer:

Step-by-step explanation:

Valeria doesnt want any lollipops left over, but identical, so that means you have to add. You can divide the two colors otherwise you get a decimal, which you cant break a lollipop into, or an indefinite letter, a lollipop cant fit in that as well. The only sensible thing is to add them.

A jar of quarters and dimes has total value of $20.70. The jar has 10 more quarters than dimes. To find the numbers of quarters

lakkis [162]

There are 62 quarters and 52 dimes in the jar.

Step-by-step explanation:

Given,

Worth of jar coins = $20.70 = 20.70*100 = 2070 cents

1 Quarter = 25 cents

1 Dime = 10 cents

Let,

Number of quarters = x

Number of dimes = y

According to given statement;

25x+10y=2070 Eqn 1

x=y+10 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$25(y+10)+10y=2070\\25y+250+10y=2070\\35y=2070-250\\35y=1820\\$

Dividing both sides by 35

$\frac{35y}{35}=\frac{1820}{35}\\y=52$

Putting y=52 in Eqn 2

$x=52+10\\x=62$

There are 62 quarters and 52 dimes in the jar.
