On first day of every month, Katie gets 590 phones to repair. She repairs 15 phones every day after that day. How many phones does she
have left to repair at the end of the 19 day of the month?

Answers

Answer:

305

Step-by-step explanation:

If she is at day 19, that means you have to multiply 15 (phones repaired each day)  times 19 (19th day) in order to get how many phones she has counted which is 285. To find how much she has left, you have to subtract 285 from 590 which gets you 305.

Answers

Answer:

1) x ≅ 51.34°

2) y ≅ 38.66°

Step-by-step explanation:

In the right triangle given in the figure

∵ The triangle has a right angle

∴ Angles x and y are acute angles and the sum of their measures is 90°

→ By using the trigonometry function tan

tan(x) = opposite side to x/adjacent side to x

∵ The opposite side to x = 10

∵ The adjacent side to x = 8

→ Substitute them in the rule above

∴ tan(x) = [tex]\frac{10}{8}[/tex] = [tex]\frac{5}{4}[/tex]

→ Use the inverse of tan to find x

∵ x = [tex]tan^{-1}[/tex]([tex]\frac{5}{4}[/tex])

∴ x = 51.34019175

x ≅ 51.34°

∵ x + y = 90°

∴ 51.34 + y = 90

→ Subtract 51.34 from both sides

y ≅ 38.66°

this doesn’t make any sense

please help lol.. i have to find the value of x..

Answers

Answer:

x = 31

Step-by-step explanation:

The sum of the internal angles = 180°

then:

2x-5 + x+10 + 2x+20 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155/5

x = 31

Check:

2*31 - 5   +  31+10   +  2*31 + 20  = 180

62-5  +   41   +  62+20 = 180

57 + 41 + 82 = 180

-64=(2cos(pi/2)+2i sin(pi/2))^n..... n=??​

Answers

Answer:

The real solution is [tex]n=6[/tex].

Step-by-step explanation:

[tex]\cos(\frac{\pi}{2})=0[/tex] while [tex]\sin(\frac{\pi}{2})=1[/tex]

So the equation becomes:

[tex]-64=(2(0)+2i(1))^n[/tex]

[tex]-64=(0+2i)^n[/tex]

[tex]-64=(2i)^n[/tex]

We know that [tex]2^6=64[/tex]. So let's see what [tex]n=6[/tex] gives us:

[tex](2i)^6=64i^6=64i^4i^2=64(1)(-1)=-64[/tex].

[tex]-64[/tex]  is the result we wanted.

[tex]n=6[/tex] is therefore a solution.
