Answer: 40 phones

Step-by-step explanation:

The company expects that every 2 out of 25 phones will have some form of defect.

In percentage terms, this is:

= 2 / 25 * 100%

= 8%

If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:

= 8 % * 500

= 40 phones

Answer:

x <40

Step-by-step explanation:

The income from the pens is 2*x

He made less than 80

2x <80

Divide each side by 2

2x/2 < 80/2

x < 40

Answer:

The question is not written correctly (and I couldn't find the actual question online), I assume that the actual question is:

"Angles A and B are complementary. If mL A = 2*x + 43 and mL B = 47°. Solve for x to find the measure of L A."

So I can answer this in a step by step way:

First, two angles are complementary if the sum of their measures is equal to 90°

Then we must have:

mL A +  mL B = 90°

If we replace these by the measures, we have:

2*x + 43° +  47° = 90°

Now we can solve this for x.

2*x + 90° = 90°

2*x = 90° - 90° = 0°

Then we must have x = 0°.

if the 20% of a number is 386, what will be 30% of the same number

Answer will be 157

If 20% of a number is 386,  30% of the same number is 579

Let the number be x.

So,we have:

20% * x = 386

Express 20% as 0.20

0.20 * x = 386

Divide both sides by 0.20

x = 1930

30% of the number is represented as:

30% * 1930

Evaluate the product

30% * 1930 = 579

Hence, 30% of the same number is 579

Answer:

The correct answer is B :)

Step-by-step explanation:

The number of k-combinations(5) from a given set S of n (24) elements

Calculating the number of combinations

Substituting our values for n= 24 and k= 5 we get

24C5 = 24!5!(24−5)!

Subtracting 5 from 24 is 19

24!5!(19)!

Expending factorial

24X23X22X21X20X19!(5X4X3X2X1)X19!

Cancelling common factors

24X23X22X21X205X4X3X2X1

Multiply numerator values and denominator values

5100480120

Divide the 5100480 by 120

Final Result :42504.0

There are 42504.0 combinations to choose 5 items out of a set of 24

Answer:

√(3)/3

Step-by-step explanation:

cos(A) = adj./hyp.

adj. = √(3) or √(3)/2

hyp. = 2 or 1

use unit circle:

hyp. = 1

adj. = √(3)/2

use pythagorean theorem c² - b² = a²

1² - (√(3)/2)² = 1 - 0.75 = 0.25

a² = 0.25

a = √(0.25)

a = 0.5

tan(A) = opp./adj.

tan(A) = 0.5/(√(3)/2)

tan(A) = 1/√(3)

rationalize

tan(A) = √(3)/3

Answer:

18 children weighed less than 50 pounds.

Step-by-step explanation:

Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.

For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.

8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.

Step-by-step explanation:
