Answer:

Janet has coins worth 252.5, 101, and 50.5.

Step-by-step explanation:

Let us call the three coins a,b, and c.

The first coin a is 5 times another coin<em> (let's say </em>b); therefore,

a = 5b,

and the third coin is 2 times the value of another coin<em> (it's coin </em>b<em>):</em>

<em />c =2b<em>.</em>

The total worth of all coins is 404; therefore,

a+b+c =404

or

5b+b+2b =404

8b =404

\boxed{b = 50.5}

with the value of b in hand, we find a and c:

a = 5b = 5(50.5)

\boxed{a = 252.5}

and for c:

c = 2 b = 2 (50.5)

\boxed{c = 101}

Thus, Janet has 3 coins worth 252.5, 101, and 50.5.

The first day of Sam's vacation was a Monday. What day of the week was the Day 36 of Sam's vacation?
makvit [3.9K]

Answer:

A. Monday

Step-by-step explanation:

The solution to this problem can be found by creating a table

If Day 1 was Monday, then

Mon    Tues      Wed      Thur    Fri      Sat      Sun

1              2           3             4        5        6          7

8             9           10           11        12       13        14

...............

We can see that the multiples of 7 are falling on Sundays so we will divide 36 by 7 to get the closest multiple of 7 to 36.

The closest multiple of 7 near 36 is 35 so Day 35th will fall on Sunday and Day 36 will be on Monday

Hence, Option A is the correct answer..
