You and your friend collect each rocks and fossils. your friend collects three times as many rocks and half as many fossils as you. you collect 20 objects. your friend collects 20 objects. how many rocks andhow many fossils do you each collect. PLEASE ANSWER FAST! I DONT WANNA FAIL!!

Answers

Answer 1

Answer:

you - 4 rocks and 16 fossilsfriend - 12 rocks and 8 fossils

Step-by-step explanation:

Let the rock be r and the fossil be f

Equations

You: r + f = 20Friend: 3r + 1/2f = 20

Double the second equation and subtract the first one:

2(3r + 1/2f) - (r - f) = 2*20 - 206r - r = 205r = 20r = 4

Then find f:

f = 20 - 4 = 16

So you collect 4 rocks and 16 fossils

Friend collects:

4*3 = 12 rocks and 1/2*16 = 8 fossils

Answers

Answer:

0.2 miles

Step-by-step explanation:

From the above question:

2 miles = 10 minutes

Hence:

10 minutes = 2 miles

1 minute = x miles

Cross Multiply

10 minutes × x miles = 2 miles × 1 minute

x miles = 2 miles × 1 minute/10 minutes

x miles = 0.2 mile

Hence in 1 minute it would take her 0.2 miles

determnine if each table shown below represents a function or not.

Answers

                                                 Table 1

Input (x)               1            3           5            5              9

Output (y)             7           16          19          20           28

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 1, it is clear that:

Each input or x-value of the X set has a unique y-value or output of the Y set. There is no duplicated input (repeated x value).

Therefore, Table 1 represents a function.

                                                Table 2

Input (x)               0.5          7           7            12            15

Output (y)             7           15          10          23           30

 

We already know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 2, it is clear that:

There is a duplicated input (repeated x value) i.e. x = 7 appears twice. And we can not have repeated input values.

As the input x = 7 is repeated multiple times, thus, the given table 2 does not represent a function.

Therefore,  Table 2 does not represent a function.

‘Saturn' chocolate bars are packed either in boxes of 5 or boxes of 12. What is the smallest number of full boxes required to pack exactly 2005 ‘Saturn' bars?

Answers

Answer:

167

Step-by-step explanation:

Given that :

Saturn chocolate bars are either packed in 5's or 12's

The smallest number of boxes required to pack 2005 bars ;

In other to arrive at smallest number of boxes, then we need to pack primarily in 12's

Number of boxes required for 12 packing :

2005 /12 = 167.08333 boxes (167, remainder 1)

Hence, smallest number of boxes to pack 2005 saturn chocolate bars is 167

Both company 1 and 2 charge $153.75 for cleaning 25 garment

Step-by-step explanation:

Equation 1

[tex]\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55[/tex]

y-62.75=4.55(x-5)

y-62.75=4.55x-22.75

c(n)=4.55x + 40

Equation 2

[tex]\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75[/tex]

y-38.75=5.75(x-5)

y-38.75=5.75x-28.75

c(n)=5.25x + 10

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

30=1.2x

x=25

f(x) when x=25

f(x)=4.55x+40

f(25)=4.55(25)+40

f(25)=113.75+40

f(25)=153.75

Both company 1 and 2 charge $153.75 for cleaning 25 garments.
