Gennadij [26K]

Answer:

30 feet is represented by 3 3/4 inches on the drawing

Step-by-step explanation:

We have the relation as;

1 inch = 8 feet

Thus;

3 3/4 inches = x feet

x = 3 3/4 * 8

x = 15/4 * 8

x = 30 feet

You and your friend each collect rocks and fossils. Your friend collects three times as many rocks and half as many fossils as y

tino4ka555 [31]

Answer:

Number of rocks and fossils collected by you is 1 and 24 respectively

Number of rocks and fossils collected by your friend is 3 and 12 respectively

Step-by-step explanation:

Let the number of Rocks you collect be x

Let the number of Fossils you collect be y

Then the total number pf objects you collected will be

x + y = 25

x = 25 - y------------------------------(1)

Your friend collects three times as many rocks and half as many fossils as you.

This can be written as

$3x + y(\frac{1}{2}) = 15$

$3x + (\frac{y}{2}) = 15$ -------------------(2)

Substituting (1) in (2)

$3(25 -y) + (\frac{y}{2}) = 15$

$75 - 3y + (\frac{y}{2}) = 15$

Grouping the like terms we get,

$75 - 15 = 3y - (\frac{y}{2})$

$60= \frac{6y-y}{2})$

$60 \times 2= 6y-y$

$120= 5y$

$y = \frac{120}{5}$

y= 24

Substituting y value in equation(1) we get

x = 25 - 24

x= 1

Friends collects 3 times rock

so collects 3x =3(1) = 3rocks

Also he collects half as many fossils

That is

$\frac{y}{2} = \frac{24}{2} =12 fossils$
