Answer:

Step-by-step explanation:

a package weighs 96

it has 6 boxes

all the boxes contain 2 bags (9 pound bag of beans and x pound bag of rice)

9 times 6 is 54

96 minus 54 is 42

since there are 6 more bags and they are or rice and they all weigh the same you would divide 42 by 6 and get 7

they are each 7 pounds

The average salary for a teacher is $55,000 per year. A physician makes on average $220,000. If you consider the earning potenti

Evgen [1.6K]

Answer:

The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000

Step-by-step explanation:

Given as :

The average salary for a teacher in a year = $55,000 per year

The average salary for a physician in a year = $220,000 per year

Let The difference between the teacher's earnings as compared to the physician's earning over 30 years = $x

Now,

The average salary for a teacher for 30 years = $55,000 × 30 = $1,650,000

The average salary for a physician for 30 years = $220,000 × 30 = $6,600,000

So,

The difference between the teacher's earnings as compared to the physician's earning over 30 years = The average salary for a physician for 30 years - The average salary for a teacher for 30 years

Or, $x = $6,600,000 - $1,650,000

∴ x = $4,950,000

So, The difference between the teacher's earnings as compared to the physician's earning over 30 years = x = $4,950,000

Hence, The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000 . Answer

Given two points A and B, there is only one segment that you can name: AB. With three collinear points A, B, and C, there are th

aksik [14]

Answer: 10

Imagine you have 2 slots or boxes that are empty. They represent the possible choices for the letter you pick. For example, you can place B in slot 1 and D in slot 2. There are 5 choices for slot 1 (A,B,C,D,E) and four choices for slot 2. Why 4? Because after we pick the letter for slot 1, we have one less letter to pick from. We can't reuse that letter.

Now multiply those values 5 and 4 to get 20. There are 20 different ways to pick a pair of letters from a pool of 5 total. However, order does NOT matter because the segment AB is the same as BA. Since order doesn't matter, we are doubly counting when we shouldn't. In other words, our count is two times higher than it should be. Instead of 20 pairs, it's actually 20/2 = 10 pairs. That's why the answer is 10.

The list of 10 segments are: {AB,AC,AD,AE,BC,BD,BE,CD,CE,DE}

Side note: you can use the nCr combination formula with n = 5 and r = 2 to get the same answer.

Verify the trig identity: tan^2 theta + cot^2 theta / csc^2 theta = sec^2 theta

Mars2501 [29]

Answer:

See proof below

Step-by-step explanation:

In trigonometry identity

tan^2 theta = sin^2 theta /cos^2 theta

cot^2 theta = cos^2 theta/sin^2 theta

csc^2 theta = 1/sin^2 theta

Substitute into the expression

(sin^2 theta /cos^2 theta )+ (cos^2 theta/sin^2 theta)/1/sin^2 theta

= [sin^4theta + cos^4theta/cos^2 theta sin^2 theta]÷(1/sin^2 theta)

= 1/cos^2 theta sin^2 theta÷(1/sin^2 theta)

= 1/cos^2 theta sin^2 theta * sin^2 theta/1

= 1/cos^2theta

= sec^2theta (Proved!)
