solong [7]4 years ago

Answer:

f

Step-by-step explanation:

You know that:

X is congruent to angle Z which means they are the same size

the straight line below is equal to 180

Y is a right angle so its equal to 90

So that means:

if x and z are equivalent that means they are equal to 2x essentially

and if you add 90 you will get the total of the line

Hope this helps!!! :)

aleksandrvk [35]

Answer:

224 stamps.

Step-by-step explanation:

We have been given that Becki put 14 stamps on each page.

To find the total number of stamps that Becki put in the book we will multiply the number of stamps put on each page by the number of completely filled pages.

\text{The total number of stamps in the book}=14\times 16

\text{The total number of stamps in the book}=224

Therefore, Becki put 224 stamps in the book.

There are 13 people on the city bus. At the first stop, four people get off and to get on. At the Second stop, six people get of
antiseptic1488 [7]

Answer:

9 people should get on stop 1.

Step-by-step explanation:

If i understood it correctly .

13 people on bus initially.

at first stop - 4 people get off . So 9 people should be on bus.

But few get in bus ( that is what is asked in the question - but it is not super clear to me)

after 2nd stop - there are 12 people on bus.

at 2nd stop  6 people got off.. so there were total of 18 on the bus

So if there were 9 people on bus stop by stop 1 .. so 9 people should have got in bus at stop 1 to make it equal to 18.

Only doubt i have is  : if the question is asking how many got on the 2nd stop.  also i was not clear what does this line means - At the first stop, four people get off and to get on.

Five dozen cds were bought for $90 a peddlar sold them at 5 for $12 calculate his profit.
valina [46]
If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66

If he sold all 60 of the CD's for 5 for $12, he'd make $144. 

Subtract the income by the original buying price to find his profit. $144 - $90

The peddler made $54 profit.
