Answer:

0.60

Step-by-step explanation:

If you purchase 6 rolls, you pay $3.60

Each roll is $0.60.

If you purchase 13 individual rolls, you pay

13 x 0.6 = $7.80

But if you purchase the Baker's dozen, you pay only $7.20, so you save $0.60

7.80 - 7.20 = 0.60

The ratio of Holly's age to that her aunt is 4:9. When holly was born her aunt was 15 years old. How old is holly's aunt now?

Lyrx [107]

Answer:

27 years

Step-by-step explanation:

Let Holly's age be h and Aunt's age be a. We can setup 2 equations and solve.

1. $\frac{h}{a}=\frac{4}{9}$

2. a - 15 = h

We can plug in equation 2 into equation 1 to solve for aunt's age:

$\frac{h}{a}=\frac{4}{9}\\\frac{a-15}{a}=\frac{4}{9}\\9(a-15)=4a\\9a-135=4a\\5a=135\\a=\frac{135}{5}=27$

Holly's aunt's age is 27

If n is an integer, n times •180degrees° represents an integer multiple of 180degrees° and (2nplus+1) times •90degrees° repre

NISA [10]

Solution: csc stands for cosecant
csc (2n+1) x 180˚
= Csc (360n +180)
= csc (180) and the csc has a period of 360˚
= 1/ sin (180)
As sin 180 = 0 so,
csc ((2n+1) x 180 degrees) is undefined as 1/0 is undefined when you calculate it in the calculator.

Answer: That seems right. Maybe you didn't simplify. Then, it would be 8/11.
