A man sold 3 times as many tie dyed shirts as white shirts. He sold 196 shirts altogether. How many tie dyed shirts did he sell?
Ivanshal [37]
We solve this the following way:

tie dyed shirts = x
white shirts = y 

x = 3y

x + y = 196

3y + y = 196 (we substitute the x with the 3y in the main equation)

4y = 196 (divide this)

y =49

x = 147

The man sold 147 tie dyed shirts and 49 white shirts.

Determine whether the forces are pulling at right angles to each other. Explain. 3.5 lb, 6.2 lb, resultant force 9.1 lb
8_murik_8 [283]
The resultant force in this item, is that which connects the heads of the magnitude of the given vectors. The magnitude of the resultant force can be calculated through the Pythagorean theorem which states that the square of the resultant force should be equal to the sum of the squares of the smaller forces. That is,
          A² + B² = C²

Investigating the vector values, 
 A² + B² = (3.5 lb)² + (6.2 lb)² = 50.69 lb²
C² = (9.1 lb)² = 82.81 lb²

Since the Pythagorean theorem is not satisfied by the given set of forces then, the forces are not in right angle. 

The answer to the question is letter C.

4. A dirt bike requires 15 L of gas to be mixed with 4 L of oil. If you use 20 L of gas, need?
coldgirl [10]

Answer:

Read down below :)

Step-by-step explanation:

Rather than taking it on and overthinking it the way everyone else does, do it the simple way, like this:

15/3 = 5, right? and 5, when multiplied by 4, becomes 20, right? So divide 4 by 3, and then take that number, and muliply it by 4.

Like this: (4 / 3) * 4, and then you know that 5 L of gas requires 1.33e L of oil. So, like 5*4 = 20, so is 1.33e *4, the amount of oil in 20 L. In all, the answer is 5.33e, or 5 \frac{3}{5} or whatever your answer might have to be
