Answer:

194.

Step-by-step explanation:

x = (7+4√3)

ludmilkaskok [199]

The recycling plant processes 480 tons of glass per day.

Step-by-step explanation:

Quantity of glass recycled each minute = \frac{1}{3}\ tons

We know that;

1 hour = 60 minutes

Therefore;

Quantity of glass recycled in one hour = \frac{1}{3}*60=20\ tons

The ratio of the measures of the angles of a triangle is 3:4:8 what are the measures of the angles?
evablogger [386]

Answer:

36 and 48 and 96

Step-by-step explanation:

add 3+4+8=15

all of the angles in a triangle have to add up to 180

so 180÷15=12

now for this ratio, each part will equal 12

so we have to multiply each of the parts by 12

3×12=36

4×12=48

8×12=96

those are the measures of the angles

you can add them up again and see that they equal 180

you can try dividing and you will see that they also equal the ratio
