It takes 9 minutes to fill an empty aquarium of a depth of 3/5 meters. What is the unit rate in minutes per meter?
GarryVolchara [31]

Answer:

<h2>The rate is 15 minutes per meter.</h2>

Step-by-step explanation:

It takes 9 minutes to fill a depth of \frac{3}{5} meters.

Filling  \frac{3}{5} meters take 9 minutes time.

Filling 3 meters of the aquarium takes 5\times9 = 45 minutes time (Multiplying by 5 both the numbers).

In order to<u> fill 1 meter of the aquarium it will take </u>\frac{9\times5}{3} = 15<u> minutes</u> (Dividing by 3 both the numerical values).

788 students at elementary school each child is giving one color T-shirt The teachers are red green yellow and blue there is an
emmainna [20.7K]
Hi,
So if I read correctly, there are 788 students each getting one of four colors of t-shirts (and there are an equal number of shirts per color). To do this, all you need to do is divide the number of students (788) by the number of colors (4) to see how many students get each color of t-shirt.

788 ÷ 4 = 197

Red is one of the four colors, and 197 is exactly one fourth of the students, so one-fourth of the students (197) get red.

o-na [289]

Answer:

d. 50°

Step-by-step explanation:

Since you know one angle and its opposite side, use the law of sines.

sin 36°/11.9 = sin D/15.6

sin D = 15.6 × sin 36° / 11.9

sin D = =0.7705

D = sin^-1 0.7705

D = 50.4°
