A company has 6582 to give out in bonuses. An amount is to be given out equally to each of 32 employees A manger Jake has reason

just olya [345]

Answer:

His estimate is not correct

Each employee gets 205.6875

Step-by-step explanation:

Bonus to give out = 6582

Number of employees to get bonus = 32

Bonus per employee = Total bonus / number of employees

= 6582 / 32

= 205.6875

Each employee will get 205.6875 contrary to manger Jake reasoning of 2000 per employee

manger Jake reasoning

6572 / 32

32 in 65 = 2 remainder 1

He added 000 zeros to 2 which is wrong

He should have added 00 zeros to 2 because he has 172 remaining after dividing 65 by 32

Triangle ABC is a right triangle, meaning we can use the Pythagorean Theorem to find x.
The formula for the Pythagorean Theorem is:
$a = \sqrt{ {b}^{2} + {c}^{2} }$
where a is the hypotenuse, and b and c are the legs.
In this problem, we have the vertical leg as 16, the horizontal leg as x, and the hypotenuse as 20. Therefore, we can say that
$a = 20 \\ b = 16 \\ c = x$
Therefore, we can plug into the formula to find x: $a = \sqrt{ {b}^{2} + {x}^{2} } \\ {a}^{2} = { \sqrt{ {b}^{2} + {x}^{2} } }^{2} \\ {a}^{2} = {b}^{2} + {x}^{2} \\ {a}^{2} - {b}^{2} = {x}^{2}$
We first change the variable c to x and square both sides of the equation. Then we subtract b^2 from both sides.
${x}^{2} = {a}^{2} - {b}^{2} \\ \sqrt{ {x}^{2} } = \sqrt{ {a}^{2} - {b}^{2} } \\ x = \sqrt{ {a}^{2} - {b}^{2} }$
We square root each side to find the variable answer for x. Then we plug in the numbers: $x = \sqrt{ {(20)}^{2} - {(16)}^{2} } \\ x = \sqrt{400 - 256} \\ x = \sqrt{144} \\ x = 12$
We find that x = 12. The answer is A. 12.

(100 - 65)

divide 40 by 100:
