Answer:

∠U = 31°

Step-by-step explanation:

∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:

∠W + 84 = 180

∠W = 96

We know that ∠W is 96°.

We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:

96 + 53 + ∠U = 180

149 + ∠U = 180

∠U = 31

Therefore, ∠U = 31°

In 5 minutes a conveyor belt moves 300 pounds of receyclable aluminum from the delievery truck a smaller belt moves the same qua

ladessa [460]

Answer:

It will take 3.214 minutes.

Step-by-step explanation:

<em>It is given that, the conveyor belt transports 300 cans in 5 mins and the smaller belt transports 300 cans in 9 minutes.</em>

Thus , the speed of conveyor belt is,

= $\frac{300}{5} = 60 cans per minute$

and of smaller belt is,

= $\frac{300}{9} = \frac{100}{3} cans per minute$

Thus, when both are used together,

<em>conveyor belt will transport (60)(t) cans and smaller belt will transport $( \frac{100}{3})$ (t) cans per minute.</em>

Thus the equation becomes,

$300 = (60)(t) + (\frac{100}{3})(t) = (\frac{280}{3})(t)$

t = $\frac{(300)(3)}{280} = \frac{45}{14} = 3.214 minutes$
