Answer:

7.1 is 10 times larger than 0.71.

Step-by-step explanation:

Let the unknown number be x.

It is given that 7.1 is 10 times larger than the unknown number. It means 7.1 is 10 times larger than x.

10 times of x = 10x

7.1 is 10 times larger than x is written as

$10x=7.1$

Divide both sides by 10.

$x=\frac{7.1}{10}$

$x=0.71$

Therefore 7.1 is 10 times larger than 0.71.

Answer:

$\frac{8}{9}$

Step-by-step explanation:

Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:

$\frac{384}{432}=\boxed{\frac{8}{9}}$

Jesse sold cupcakes and cookies yesterday. Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Je

ale4655 [162]

Answer: 19 cupcakes and 37 cookies were sold.

Step-by-step explanation:

Let x represent the number of cupcakes that Jesse sold yesterday.

Let y represent the number of cookies that Jesse sold yesterday.

If he sold 56 cupcakes and cookies combined, it means that

x + y = 56

Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Jesse had sold $37.75 worth of cookies and cupcakes. This means that

1.5x + 0.25y = 37.75 - - - - - - - - - - -1

Substituting x = 56 - y into equation 1, it becomes

1.5(56 - y) + 0.25y = 37.75

84 - 1.5y + 0.25y = 37.75

- 1.5y + 0.25y = 37.75 - 84

- 1.25y = - 46.25

y = - 46.25/ - 1.25

y = 37

x = 56 - y = 56 - 37

x = 19
