Olin [163]
Ok so mean means average so exmple
mean of 1,2,3+5 would be (1+2+3+5)/4
(sum of terms)/(number of terms)=mean so

number of terms=5 since 5 oranges
sum=(46+39+53+61+49)

so mean=(46+39+53+61+49)/5=248/5=49.6

so the answer would be 49.6 (estimateed to be 50)

Radda [10]

Answer: 16

Step-by-step explanation:

The constant of proportionality is a ratio that exist between two directly proportional quantities. From the question, recipe says to use 1.5 cups of flour to make 24 cookies.

y = the number of cookies made

x = the number of cups of flour used

y = kx

k = y/x

k = 24/1.5

k = 16

Therefore, the constant of proportionality which relates the number of cookies made, y, to number of cups of flour used, x is 16.

A rectangular is 4 times as long as it is wide . if the area is 16 square feet, find its perimeter
RSB [31]

if say we have a widht of w, and its length is <u>4 times as long as </u><u>w</u>, then its length is 4*w or 4w.


\bf \textit{area of a rectangle}\\\\ A=Lw~~ \begin{cases} L=4w\\ A=16 \end{cases}\implies 16=(4w)w\implies 16=4w^2 \\\\\\ \cfrac{16}{4}=w^2\implies 4=w^2\implies \sqrt{4}=w\implies \boxed{2=w} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{perimeter}{\stackrel{L}{4(2)}+\stackrel{w}{2}\implies 10}\hfill
