If Keira spends $45 on petrol, 1/ 9 of the money on other items and 1 /5 of the money on clothes. How much money does she spend
gogolik [260]

Answer:

The money Keira spent on food is $31.

Step-by-step explanation:

Total money spent by Keira = $45

Things Keira spent money on:

1. Clothing

2. Food

3. Other items

Money spent on Clothing = 1/5 of total money

= 1/5 x $45

Money spent on Clothing = $9

Money spent on Other Items = 1/9 of total money

= 1/9 x $45

Money spent on Other Items = $5

Money spent of on Food = Money spent - (Money spent on clothing + other items)

Money spent on food = 45 - (9+5)

= 45 - 14

Money spent on food = $31

A special deck of cards has ten cards. Four are green (G), four are blue (B), and two are red (R). When a card is picked, the co
a_sh-v [17]

Answer:

{GT, GH, BT, BH, RT, RH};

1 /5;

Mutually exclusive ;

Not mutually exclusive.

Step-by-step explanation:

Given :

Green cards, G = 4

Blue cards, B = 4

Red cards, R = 2

For a coin toss :

{H, T}

A card is picked, then a coin is tossed :

Sample space :

{GT, GH, BT, BH, RT, RH}

2.) probability of picking a green card, then probability of landing a head on a coin toss

P(A) = number of required outcome / Total possible outcomes

P(A) = P(green card) * P(Head)

P(A) = (4 / 10) * (1/2)

P(A) = 4 /20

P(A) = 1/5

C.)

Both A and B are mutually exclusive, since both event A and event B cannot occur together, since both red and green cannot be picked during a single pick, this either a red is picked or green is picked, then they are A and B are mutually exclusive.

D.) Event A and C are not mutually exclusive, picking a green card, event A and picking a red or blue card, event B. Both event can happen simultaneously, hence, event A and B are not mutually exclusive.

Find the area of a rectangle with the length of 1 3/4 foot and a width of 1 1/2 foot.
Stolb23 [73]
To find the Area you need to use the formula L x W!! Anyways, You have to multiply the Length x the width. Your Length is 1 3/4 and your width is 1 1/2. So 1 3/4 x 1 1/2 is 2 5/8!!
