6 0

Answer: y=37.5degrees and x=110degrees

Step-by-step explanation: sum of angle in a quadrilateral =360 and opposite angles=180. 115+2y=180,2y=180-115=75. 2y/2=75/2. therefore y=37.5. while x=70+x=180,x=180-70=110. x=110

an Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?
Arturiano [62]

Answer:

45

Step-by-step explanation:

This is a trick question. Since they only get three purchases in by 7 weeks, the answer will be 15 times 3 or 45.

(If I'm wrong and it's not a trick question, then it's 15 times 3.5 or 52.5)

Hope this helps!

Simplify 9 to the 2nd over 9 to the 7th.
sattari [20]
The answer is 1. 9 over 9 is a whole, which is one. 1 to the second power is 1. 1 to the 7th power is 1. No matter how many exponents you put on 1, it will always stay one. So the answer is 1.

Tommy wished he practiced more before his violin concert. If he had practiced 1 1/2 more hours one week, he would have averaged
Nimfa-mama [501]

Answer:

30.5 hours

Step-by-step explanation:

If he were to average 8 hours PER week for 4 weeks, his total sum would have been:

8 * 4 = 32 hours

But he fell short of it. By how much?

By 1\frac{1}{2} hours!

So, he practiced 1  1/2 hours LESS THAN 32 hours, so his practice time is:

32-1\frac{1}{2}\\=32-1.5\\=30.5\\=30\frac{1}{2}

So, <u>he practiced 30.5 hours in the 4 weeks</u>
