Answers

Answer 1

Answer:

Points ( 0, 13) , ( 30, 18) , ( 90 ,28)

Rate = y2-y1/x2-x1

Rate = 28-13 / 90-0 = 1/6 inches / Mins

Rate = 18-13/30-0 = 1/6 inches / Mins

can you scale up to 1,120 from 2? or, can you determine how many moose per one person?

Answers

The scaling up of 1,120 from 2 requires that we have; 560 moose per one person.

Scaling up 1,120 from 2 requires determining the conversion factor of 2 to 1,120

Conversion factor, c.f = 1,120/2

c.f = 560

In essence, the scaling up of 1,120 from 2 requires that we have; 560 moose per one person.

Answer:

174

Step-by-step explanation:

5⋅2+4⋅6+10+123+(8)−1

Multiply 5 and 2 to get 10. Multiply 4 and 6 = 24.

10+24+10+123+8−1

Add 10 and 24 =34.

34+10+123+8−1

Add 34 and 10 =44.

44+123+8−1

Add 44 and 123 =167.

167+8−1

Add 167 and 8 =175.

175−1

Subtract 1 from 175 = 174.
