Answer:

Total Distance = 8.37 cm

Step-by-step explanation:

D = π2r

D = π2(8)

D = 16 π

D = 50.24

T = 60 = 1hr

T = 60/10 = T x D = 1/6 x 50.24

Total D = 8.37 cm

Alternative is we can take 1/6 as a decimal = 0.1666 x 50.24 = 8.37 cm

Hey.

acc'g to the conditions :

Let Catherine has x
and James has 5 + 3x

Then,

$5 + 4x = 41 \\ \\ \implies 4x +5 -5 = 41-5 \\ \\ \implies 4x = 36 \\ \\ \implies x= \dfrac{36}{4} \\ \\ \implies x = 9$

Hence

• Catherine has = x = $9,
• and James has = 5 +3x = 5 + 3(9) = $32

Thanks.

Step-by-step explanation:

Tom = s

Nancy = r

s=r-2 = Tom=Nancy-2

This means that Tom has $2 less than Nancy as they stayed in the information they gave us. They want us to complete the graph.

Since Tom has $2 less than Nancy all we have to do is apply rule -2 to each number.

4-2=2

8-2=6
