Answer:

$\large \boxed{4}$

Step-by-step explanation:

$\text{No. of students} = \dfrac{\text{Total distance}}{\text{Distance per student}}$

$\begin{array}{rccl}16\frac{2}{3} \div4\frac{1}{6}& = & \dfrac{50}{3} \div \dfrac{25}{6} & \text{Mixed numbers to improper fractions}\\\\ & = & \dfrac{50}{3} \times \dfrac{6}{25} & \text{Inverted 2nd fraction and changed to multiply}\\\\ & = & \dfrac{2}{3}\times \dfrac{6}{1} & \text{Cancelled the 25s}\\\\ & = &\dfrac{2}{1}\times \dfrac{2}{1} & \text{Cancelled the threes}\\\\ & = &\mathbf{4} & \text{Multiplied the fractions}\\\end{array}\\\large \boxed{\textbf{Four}} \text{ students went on the trip.}$

the museum wants to display all the art pieces in rows. Each row has the same number of pieces and the same type of pieces. How

Alecsey [184]

So if you have 30 oil, 24 photos, 21 sketches, the first thing I notice is that all of these numbers are divisible by 3. Since there are no specifications of how many rows for each category. You can divde the 30/10, 24/8, and 21/7 you would have 10 rows oil, 8 rows of photos, and 7 rows of sketches. In short, I believe your answer should be 3.

Hope this helps! Sorry if this explanation is unclear, please feel free to ask questions. <3

Triangle ABC and triangle CDE are similar right triangles. Which proportion can be used to show that the slope of AC is equal to

Marianna [84]

Answer:

(6 - 3)/(-3 - (-1))

(3 - (-3))/(-1 - 3)= 6/(-4)

Step-by-step explanation:

Slope AC = (y(A) - y(C))/(x(A) - x(C)) = (6 - 3)/(-3 - (-1)) = 3/(-2)

Slope CE = (y(C) - y(E))/(x(C) - x(E)) = (3 - (-3))/(-1 - 3)= 6/(-4) = 3/(- 2)
