Jenny is 9 years younger than Sammie. Five years ago, Sammie was four times older than Jenny. How old is each now?

Answers

Answer:

Jenny's is 8 now and Sammie is 17.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

Jenny's age is x.

Sammie's age is y.

Jenny is 9 years younger than Sammie.

This means that:

[tex]x = y - 9[/tex]

Five years ago, Sammie was four times older than Jenny.

This means that:

[tex]y - 5 = 4(x - 5)[/tex]

Since [tex]x = y - 9[/tex]

[tex]y - 5 = 4(y - 9 - 5)[/tex]

[tex]y - 5 = 4(y - 14)[/tex]

[tex]y - 5 = 4y - 56[/tex]

[tex]3y = 51[/tex]

[tex]y = \frac{51}{3}[/tex]

[tex]y = 17[/tex]

[tex]x = y - 9 = 17 - 9 = 8[/tex]

Jenny's is 8 now and Sammie is 17.

A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12). Find the probability of rolling a number greater than 12.
The probability of rolling a number greater than 12 is
(Type an integer or a simplified fraction.)

Answers

Answer:

[tex]P(x>12) = 0[/tex]

Step-by-step explanation:

Given

[tex]x = \{1,2,3,4,5,6,7,8,9,10,11,12\}[/tex] --- outcomes

[tex]n(x) = 12[/tex] -- sample size

Required

[tex]P(x > 12)[/tex]

This is calculated as:

[tex]P(x > 12) = \frac{n(x > 12)}{n(x)}[/tex]

[tex]n(x>12) = 0[/tex] because none of the outcomes is greater than 12:

So:

[tex]P(x > 12) =\frac{0}{12}[/tex]

[tex]P(x>12) = 0[/tex]

Sally is making 15 individual blueberry cheesecakes. How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

Answers

Answer:

0.35 pounds in each cheesecake

Step-by-step explanation:

Number of individual blueberry cheesecakes = 15

Pounds of blueberries = 5 1/4 pounds

How many pounds of blueberries will be in each cheesecake if 5 1/4 pounds of blueberries are divided equally among them?

= 5 1/4 ÷ 15

= 21/4 ÷ 15

= 21/4 × 1/15

= (21*1)/(4*15)

= 21/60 pounds

Equivalent to 0.35 pounds in each cheesecake

which one is greater/less than?

-25% or 25%

Answers

Answer:

25% is greater then -25.

Step-by-step explanation:

-25 is in the negiatives, and is to the left of 0. Anything to the left of 0 will be less then anything on the right of 0. :D

-25% will always be less than 25% because a negative number, being less than 0, will always be less than a positive number, being greater than 0.

Thus, -25% is less than 25% or 25% is greater than -25%
