Lily saved 16 coins. She saved ten-can and one-dollar coins only. If she had $5.20, how many ten-cent coins did she have?

Firlakuza [10]

Answer:

Step-by-step explanation:

Let d represent the number of dimes Lily saved. Then the value of her coins in cents is ...

10d +100(16-d) = 520

-90d +1600 = 520 . . . . . eliminate parentheses, collect terms

-90d = -1080 . . . . . . . . . . subtract 1600

d = -1080/-90 = 12 . . . . . divide by the coefficient of d

Lily has 12 ten-cent coins.

Solve 6 sin((π/5)x)=5 for the four smallest positive solutions

cupoosta [38]

Answer:

1.568, 3.432, 11.568, 13.432

Step-by-step explanation:

Divide equation $6\sin\left(\dfrac{\pi }{5}x\right)=5$ by 6:

$\sin\left(\dfrac{\pi }{5}x\right)=\dfrac{5}{6}.$

Then

$\dfrac{\pi }{5}x=(-1)^k\arcsin\left(\dfrac{5}{6}\right)+\pi k,\ k\in Z,$

$x=(-1)^k\dfrac{5}{\pi }\arcsin\left(\dfrac{5}{6}\right)+5k,\ k\in Z.$

Since $\arcsin\left(\dfrac{5}{6}\right)\approx 56^{\circ}\approx \dfrac{\pi }{3.2},$

four smallest positive solutions are

1. $\dfrac{5}{3.2}\approx 1.568,\ k=0;$

2. $\dfrac{-5}{3.2}+5\approx 3.432,\ k=1;$

3. $\dfrac{5}{3.2}+10\approx 11.568,\ k=2;$

4. $\dfrac{-5}{3.2}+15\approx 13.432,\ k=3.$

I'll probably post alot of math, that's what I need to get 80% in today and I have like 50%

ExtremeBDS [4]

Answer:

Step-by-step explanation:

1. (6/a)x + 5 = 4

(6/a)x = -1

6x = -a

x = -a/6

2. 2ax + 7 = 13

2ax = 6

ax = 3

x = 3/a

3. -ax - 20 = -14

-ax = 6

x = -6/a
