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

e is 7.4 feet long and weighs 1.2 tons. Each truck is 16 feet long and weighs 2.8 tons. Write an inequality you could use to find the number of trucks t that can fit on the bridge when there are 10 cars in the bridge.

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.

How many times does 11 go into -435 pls dont cheat​
hodyreva [135]
If you do 435 divided by 11, your answer would be the amount which is not a whole number, it’s 39.5454 and goes on.

but since you said NEGATIVE 435, 11 can’t go into that negative so it’ll be zero.

If \triangle ABC△ABC is equilateral, solve for x. <br><br><br><br><br> x=
Gwar [14]

Answer:

x = 13

Step-by-step explanation:

The tirangle ABC is given as equilateral. Every angle is therefore =. Not only that, each angle is 60 degrees.

If you need proof of that, remember that x + x + x  = 180. Every triangle has 180 degrees.

if 3x = 180 then 1 x is 60

8x - 44 = 60       Add 44 to both sides.

8x = 60 + 44

8x = 104             Divide by 8

x = 104/8

x = 13
