juin [17]

Answer:

52.5n+449.85

Step-by-step explanation:

The cost is given for <em>1 sweatshirt</em>. To find the cost of 15 sweatshirts, we need to multiply the expression by 15. Let's do this:

15(3.5n+29.99)\\=15(3.5n+29.99)\\=15(3.5n)+15(29.99)\\=52.5n+449.85

This is the expression that represents the cost of 15 sweatshirts.

Help me with this please!!!!!!!!!!!!!!!!!!!!!
Andrej [43]

Answer:

y = 2 units

Step-by-step explanation:

We can solve this in 2 ways, both ways would give the same answer:

<u>#1) Sin(45) = </u>\frac{\sqrt{2} }{y}<u />

=> Sin(45) * y = \sqrt{2}

=> y = \frac{\sqrt{2} }{Sin(45)}

=> y = 2

<u>#2) Cos(45) = </u>\frac{\sqrt{2} }{y}<u />

=> Cos(45) * y = \sqrt{2}

=> y = \frac{\sqrt{2} }{Cos(45)}

=> y = 2

Hope this helps!
