What is the value of y?

Mathematics
1 answer:
nika2105 [10]2 years ago
4 0

Answer:

y =24

Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles

y+18  + 3y -41  = y+49

Combine like terms

4y -23 = y+49

Subtract y from each side

4y -y -23 = y+49-y

3y -23 = 49

Add 23 to each side

3y -23+23 = 49 +23

3y = 72

Divide by 3

3y/3 = 72/3

y =24

During a period of 6 months, MegaCorp had monthly profits of $3.2 million, $1.8 million, and $6.4 million. Two months had losses
Feliz [49]
1. Add up all the profits:
3.2 + 1.8 + 6.4 = $11.4 million
2. Add up all the losses:
4.5 + 2.7 = $7.2 million
3. Profits - Losses = Total Profit so far
$11.4 million - $7.2 million = $4.2 million 
4. What happened in the last month?
The net profit is $7.5 million. This means the last month must have had a profitable month to equal $7.5 million. 
7.5 - 4.2 = $3.3 million profit in the last month

If the sum of $1! + 2! + 3! + \cdots + 49! + 50!$ is divided by $15$, what is the remainder?
kompoz [17]

Answer:

  3

Step-by-step explanation:

All factorials 5 and above are evenly divisible by 15, so have no remainder. Thus, you are interested in ...

  mod(1! +2! +3! +4!, 15) = mod(1 +2 +6 +24, 15)

  = mod(33, 15) = 3

The remainder is 3.
