Sorry I had to upload a question
Answer:
A lot of work
Step-by-step explanation:
A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52
Answer:
103.18units³
Step-by-step explanation:
Area of the sector DEF = theta/360 * πr²
r is the radius
theta is the angle subtended at the centre
theta =70 degrees
radius DE = 13units
Substitute
Area of the sector = 70/360 * 3.14(13)²
Area of the sector = 7/36 * 530.66
Area of the sector = 3,714.62/36
Area of the sector = 103.18units³ (to the nearest hundredth)
1) Two triangles are similar if they have congruent angles and proportional sides (for each corresponding leg).
2) So let's check whether there are similar triangles by setting a proportion:

3) So yes they are similar, i.e. ΔCAB ~ΔHGJ
