A breakfast stall at a market stays

Mathematics
1 answer:
zheka24 [161]2 years ago
6 0

Answer:

If it opens at 5:30, then it closes at 10:00 AM

If it opens at 6, then it closes at 10:30 AM

If it opens at 6:30, then it closes at 11:00 AM

If it opens at 7, then it closes at 11:30 AM

If it opens at 7:30, then it closes at 12:00 PM

After 12:00 PM, no one is going to have breakfast. So these are the only possibilities of the timing it will open. Either at 5:30, 6, 6:30, 7, or 7:30.

Simplify the expression of (7 – c )(–1)
Ivan
Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c 
thus putting them together to get -7+c which is just c-7

Area <br> help hellllppppp
slega [8]

Answer:

Area = 14¹/16 yd² or 14.0625 yd²

Step-by-step explanation:

2. The figure given is a square having equal sides of 3¾ yd each.

Formula for area of the square = a²

Where,

a = 3¾ yd

Plug in the value into the equation:

Area = (3¾)²

Change to improper fraction

Area = (15/4)²

Area = 225/16

Area = 14¹/16 yd² or 14.0625 yd²

Your friends shuffle the cards and then deal them. Select probability of getting a red card. Select probability of getting a spa
sladkih [1.3K]

Answer:

1/2 ; 1/4

Step-by-step explanation:

Number of cards in a deck = 52

Number of red cards = 26

Number of spades = 13

Probability of event A :

P(A) = required outcome / Total possible outcomes

P( red card) = number of red cards / total cards in deck

P(red card) = 26 / 52 = 1/2

P(spade) = number of spades / total cards in deck

P(red card) = 13 / 52 = 1 / 4

Please help me solve this
seropon [69]

9514 1404 393

Answer:

  103°

Step-by-step explanation:

The law of sines tells you ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin(c/a·sin(A)) = arcsin(37/19·sin(30°)) ≈ 180° -76.8° ≈ 103°

Obtuse angle C is about 103°.
