Write 336 mi in 11.2 h as a rate in simplest form

Mathematics

arsen [322]2 years ago

Answer:

  30 mL/h

Step-by-step explanation:

You want the rate 336 ml in 11.2 h as a rate in simplest form.

<h3>Unit rate</h3>

The rate can be expressed in simplest form in a number of ways. We usually want rates involving time to be expressed with time units in the denominator:

  (336 mL) / (11.2 h) = 30 mL/h

__

<em>Additional comment</em>

Medicine is often prescribed on a "per day" basis. In 24 hours, this rate would be ...

  (30 mL/h)×(24 h/day) = 720 mL/day

The machine setup to dispense this medicine might use time units of minutes:

  (30 mL/h) / (60 min/h) = (1/2) mL/min

Answer: Isosceles

<u>Step-by-step explanation:</u>

Given: AB || DE ,  BC is a transversal

∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°

∠DCA, ∠ACB, & ∠BCA are supplementary  --> ∠ACB = 50°

By the Triangle Sum Theorem, ∠A+∠B+∠C  = 180° --> ∠CAB = 50°

Triangle is isosceles because ∠A ≅ ∠C

Y_Kistochka [10]
X=1
y=-1.5(1)
y=-1.5
(1,-1.5)

x=0
y=-1.5(0)
y=0
(0,0)

x=2
y=-1.5(2)
y=-3
(2,-3)

x=3
y=-1.5(3)
y=-4.5
(3,-4.5)

all you do is substitute the x value in the equation to get y
