Answer:

255 ¢ or 2.55$

Step-by-step explanation:

i counted like this

l    30 seconds   = 1

l    1 minute         = 2

l    1.5 minutes    = 3

l    2 minutes      =  4

l    2.5 minutes   =  5

l    3 minutes      =  6

l    3.5 minutes   =  7

l    4 minutes      =  8

l    4.5 minutes   = 9

l    5 minutes      = 10

l    5.5 minutes   = 11

l    6 minutes      =  12

l    6.5 minutes   = 13

l    7 minutes      = 14

l    7.5 minutes   = 15

 So then 17 ¢ x 15 = 255 ¢

A football team has a squad of 24 players,
lora16 [44]
Answer: 1/3

Explanation:

1/12 of the squad are suspended:

1/12 x 24 = 24/12 = 2

So 2 player are suspended

24 - 2 = 22 player

And some are injured leaving 14 left to play:

22 - 14 = 8 players injured

So 8/24 is the fraction of injured player.

But 8/24 = 1/3 so we can say 1/3 of the whole squad are injured.

Plz help last one ty!!!!!!!

My apologies on answering late...

Same situation as the previous problem, but this time, all you need to do is state the degree of the angle instead of just providing the angle itself.


ΔABC ≅ ΔDEF

Now, we can see that ∠C ≅ ∠F. Using this information, we can find ∠C on the first triangle ( which is 75° ).

Since ∠C ≅ ∠F,

m∠F is 75°.


Hope I caught your question in time!

Have a good one! If you need anymore help, let me know.
