Answer: 56.1 (I think & hope lol)

Step-by-step explanation:

The height of the pole is 18 & the height from the top of the pole to the ground is 15. So you’ve got your hypotenuse (18) & ur opposite (from the angle: 15). That gives you Sin(theta). So sin(theta)= 15/18. Divide 15/18 & get .83. Use the inverse of sin (sin^-1(.83)) to get that the angle is 56.1. Hopefully that’s correct

A factory has four machines that produce the same item. Machines 1 and 2 each produce 20% of the total output, while machines 3
andrezito [222]

Answer:

The answers are a. 0.27 b. 0.2 c. 0.2 d. 0.3 e. 0.3 f. 1

Step-by-step explanation:

Total output = 100% = 1

Total defective = 6% + 5% + 8% + 8% = 27% = 27

a. Prob of defective item = total defective/total output

= 27/100

= 0.27

b. Prob of defective from machine 1 = 6/27 =0.2222

~ 0.2

c. Prob of item defective from machine2 = 5/27 = 0.1852

~0.2

d. Prob of de defective from machine 3 = 8/27 = 0.2963

~0.3

e. Prob of defective from machine 4

= 8/27 = 0.2963

~ 0.3

f. Sum of prob from b-e

0.2 + 0.2 + 0.3 + 0.3

= 1

May someone help please fast! Thanks!

Answer:

10m

Step-by-step explanation:

We can set up an equation to solve this.

\frac{20}{25} =\frac{8}{x}

This equation can be created since we are given two similar sides of both triangles.

Now, cross multiply and simplify to solve for x.

20x=200\\x=10

The answer is sensible, and if you put 10 into the same equation from earlier, you will see that it is accurate.

Therefore, the value of x is 10m.

The area of a rectangle is 229.2 m2. If the length is 15 m, what is the perimeter of the rectangle
igor_vitrenko [27]

Answer:

\large\boxed{P=60.56\ m}

Step-by-step explanation:

The formula of an area of a rectangle:

A=lw

l - length

w - width

We have

A=229.2\ m^2\\\l=15\ m

Substitute:

15w=229.2          <em>divide both sides by 15</em>

w=15.28\ m

The formula of a perimeter of a rectangle:

P=2(l+w)

Substitute:

P=2(15+15.28)=2(30.28)=60.56\ m
