There are 52 weeks in a year, and you work 40 hours a week how much do you need to make an hour to make $60,000 a year?

1 answer:

7 0

First you need to multiply 52 x 40 = 2080
then you need to divide 2080 from 60,000.
The answer will be 60000/2080 is approximately $28.85

Find integers a, b, and c such that a) a | (b - c) but a - b and a - c b) a | (2b + 3c) but a - b and a - c

seraphim [82]

Answer:

Part a) (a,b,c)=(10,19,9)

Part b) (a,b,c)=(9,3,1)

Please let be know if I have interpreted your question correctly. Thank you.

Step-by-step explanation:

Part a)

This is the way I interpret part a:

Find integers a,b,c such that a|(b-c) but a does not divide b and a does not divide c.

There are many triples satisfying part a.

One such triple is (a,b,c)=(3,10,7).

3 divides 10-7

But 3 does not divide 10 and 3 does not divide 7.

Another example is (a,b,c)=(2,7,5).

2 divides 7-5

But 2 doesn't divide 7 and 2 doesn't divide 5.

I will give another example.

(a,b,c)=(10,19,9)

10 divides 19-9

But 10 doesn't divide 19 and 10 doesn't divide 9

Part b)

This is the say I interpret part b:

a | (2b + 3c) but a does not divide b and a does not divide c

So lets let b=2 and c=5, then 2b+3c=19.

We just need to choose an a such that it divides 19 but not 2 and 5. That should be easy. 19 itself will do that.

So one (a,b,c) could be (19,2,5).

Let's try for another example.

Let b=3 and c=1.

Then 2b+3c=9.

So we just need to find an a that divides 9 but not 3 and not 1.

9 works.

So another example is (9, 3,1).

Tyana has a collection of hoodies and t-shirts. She has 561 pieces of collected clothing in all. The number of hoodies is twice

Delicious77 [7]

Answer:

187 t-shirts and 374 hoodies.

Step-by-step explanation:

(t is shirts)

561 = t + (2t)

561 = 3t

/3. /3

187 = t

ck:

187 + ( 2 times 187) = 561

187 + 374 = 561

561 = 561

Two hikers are 55 miles apart and walking toward each other. They meet in 10 hours. Find the rate of each hiker iſ one hiker wal

ExtremeBDS [4]

Answer:

Speed of hikers are 4.4 mph and 7.7 mph

Step-by-step explanation:

Two hikers are 55 miles apart and walking towards each other.

They meet after 10 hours.

Let the speeds of hikers are S and S' mph.

One hiker walks 3.3 mph faster than the other,

S = 3.3 + S'

S' = S - 3.3

Distance traveled by the hiker with higher speed S = Speed × Time

$d_1=S\times 10$

$d_1=10S$

Distance traveled by the slower hiker $d_2$ = (S - 3.3) × 10

Total distance between them = 55 miles

$d_1+d_2=55$

10S + 10(S - 3.3) = 55

20S - 33 = 55

20S = 88

S = 4.4 mph

Speed of first hiker = 4.4 mph

Speed of second hiker = 4.4 + 3.3 = 7.7 mph
