Tom has 12 cards with the numbers 1 to 12 on them.
Anna71 [15]

Answer:

5/12

Step-by-step explanation:

Given that,

Total no of cards = 12 with numbers 1 to 12

We need to find the probability of getting 5.

Probability = favourable outcomes/total no of outcomes

Favourable outcomes is 5 as it come one time

Total no of outcome = 12 (total no of cards)

So,

P(5)=\dfrac{5}{12}

Hence, the probability of getting 5 is 5/12.

Carter is selling his bike. His research shows that the bike has a current value of $90, which is 45% of the amount Carter paid
GaryK [48]

Carter paid $200 for the bike.

Step-by-step explanation:

Given,

Current value of bike = $90

This represent 45% of the original amount Carter paid for bike.

Let,

x represent the original amount of bike.

45% of x = 90

\frac{45}{100}x=90\\\\0.45x=90

Dividing both sides by 0.45

\frac{0.45x}{0.45}=\frac{90}{0.45}\\x=200

Carter paid $200 for the bike.

damaskus [11]
One Square Meter= 10.764 Square Feet.
The total area of the quilt in meters is 4.465m^{2}
As you're looking for square feet, you've then got to multiply this by 10.764
4.465*10.764= 48.06086 square feet.
Rounded, this is 48.06 square feet.
Hope this helps :)
