Answer:

2/5 or 2:5

Step-by-step explanation:

Face Card:

The face cards in a deck are the Jack, Queen, and King. There are 4 of each card (1 in each suit), for a total of 12 face cards.

Spade:

1/4 of all the cards in a deck are spades, so 52/4= 13 spades.

When added, the numerator of the probability is 25, however, because the Jack, Queen, and King of Spades are duplicated, we have to subtract 3.

25-3=22

22/55

when simplified: 2/5

ANSWER:

There are 52 cards in total.

Hence, total Outcomes =52

Probability of the card drawn is a card of spade or a face card:

Total cards of Spade = 13

Total face card = 12

Number of face card of Spade = 3

Therefore,

Probability of the card drawn is a card of spade or a face card:

$\sf\frac{13}{52} + \frac{12}{52} - \frac{3}{52}$

$\sf\frac{13 + 12 - 3}{52}$

$\sf\frac{\cancel{22}}{\cancel{52}} = \frac{11}{26}.$

Answer:

3) 16.2

Step-by-step explanation:

The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:

CB/CD = CF/CA

CB = CD·CF/CA = 7.2·21.6/9.6

CB = 16.2

_____

When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
