Answer:

2/5

Step-by-step explanation:

4ounces of coffee in cup  1

4 ounces of cream in cup 2

In the first step  pour 4/2=2 ounces of coffee from cup 1 to cup 2, getting:

2 ounces of coffee in cup 1

2 ounces of coffee and 4 ounces of cream in cup 2

In the second step we pour 2/2=1 ounce of coffee and 4/2=2 ounces of cream from cup 2 to cup 1, getting:

2+1=3 ounces of coffee and 0+2=2ounces of cream in cup 1

so the answer is 2/5

Given the equation y=4x-3, if x increases by 2 unit, what is the corresponding change in y
shutvik [7]

y increases by 8

given y = 4x - 3 then an increase in x of 2 units gives

y = 4(x + 2) - 3 = 4x + 8 - 3 = 4x + 5

change in y = 4x + 5 - (4x - 3) = 4x + 5 - 4x + 3 = 8

What is the linear diameter (in meters) of an object that has an angular diameter of 22
Mumz [18]

Answer: 0.15 m

Step-by-step explanation:

Using the small angle formula

D= kd/206265 where

k= 22 and d= 1400

D= 22 x 1400/206265

D=0.149 m

Hence the linear diameter is 0.15 m.
