\csc(-330^o)=\csc(-330^o+360^o)=\csc30^o=\dfrac{1}{\sin30^o}=\dfrac{1}{\frac{1}{2}}=1\cdot\dfrac{2}{1}=2

In Juan's coin bank there are nickels (n),
alukav5142 [94]

Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

  1. First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
  2. Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
  3. 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
  4. 75d= 600 x 4
  5. d=600 x 4/75 (same here put everything over 75)
  6. d=32
  7. So then n= 2 x 32/4 = 16
  8. Then n would be equal to : 1/4d= 1/4 x 32 = 8
  9. So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)

Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost​
vitfil [10]

Answer:

The answer is $8.00.

Step-by-step explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00
