patriot [66]

Answer:  104 men work for the company

115 = l \times 2.5 \times 5.75

\huge \mathrm{Answer࿐}

given :

\longmapsto volume = 115 yd³

Dimensions are :

  • 2\frac{1}{2} yd

  • 5\frac{3}{4} yd

  • L

We know,

\large \boxed{ \mathrm{volume = l \times b \times h}}

  • 115 =  2\frac{1}{2}  \times  5\frac{3}{4}  \times l

  • l \times  \dfrac{5}{2}  \times  \dfrac{23}{4}  = 115

  • l  \times  \dfrac{115}{8} = 115

  • l = 115 \times  \dfrac{8}{115}

  • l = 8 \: yd

Therefore Length of the prism is 8 yards.

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes, and 20 pages in 30 minutes. I’d this a proportional relat
Alex73 [517]

Answer:

Y= 1.5x

Step-by-step explanation:

What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)

I hope this will help
