Black_prince [1.1K]

Answer:

\frac{4}{21}

Step-by-step explanation:

Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:

P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another

                            type then a $10 bill)

                        = \frac{5}{15}*\frac{10}{14}+\frac{10}{15} *\frac{5}{14} = \frac{4}{21}

A bridge has a single lane and is 122 feet long. The weight limit for the bridge is 20 tons. Each car that might be on the bridg
gulaghasi [49]

Answer:

2.8 t ≤  12 tons  ,  16 t  ≤   48 feet are the required inequalities to find the number of trucks t on a bridge.

Step-by-step explanation:

The number of trucks on the bridge = t

Number of cars = 10

Total length of Bridge = 122 ft, and weight = 20 tons

Total length of Car = 7.4 ft, and weight = 1.2 tons

Total length of truck = 16 ft, and weight = 2.8 tons

Now, there are 10 cars on the bridge.

So, total length of bridge covered = 7.4 x 10 = 74 feet

Hence, the available length of bridge for trucks = 122 - 74 = 48 ft

Also, total weight of bridge covered = 1.2 x 10 = 12 tons

Hence, the available weight  of bridge for trucks = 20 - 12 = 8 tons

Hence, according to the question:

2.8 t ≤  12 tons    and

16 t  ≤   48 feet are the required inequalities to find the number of trucks t on a bridge.

The solution to -5 m = -20 is negative.
lianna [129]
No it's positive since if you multiply both sides by -1 you will get 5m=20 & m=4

Another method -5m =-20, divide both sides by -5, you will get the same positive m =4
