Answer:

From noon to 3 pm, there are three hours so the average speed Isaiah will need to arrive in another city in 3 hours is 186/3 = 62 km/h. Since this is less than the speed limit, Isaiah can go an average speed between 62 km/h to 65 km/h to arrive at the second city on time.

10 / 25 = $ 0.4 per unit
18.50 / 50 = $ 0.37 per unit
27.20 / 80 = $ 0.34 per unit
a.) $ 0.85 - $ 0.72 = $ 0.13

Use the Cosine Rule

q^2 = 20^2 + 30^2 - 2^20*30 cos 15

       =  140.89

so q = sqrt 140.89 =  11.9 (answer)

If (a+b) / (x−y) = 3/5 then (10a + 10b) / (9x−9y) = ?
lbvjy [14]

Answer:

2/3

Step-by-step explanation:

Look at what you are getting on the right hand question. 10a +10b has a common factor that can be pulled out. It is 10

10a + 10b = 10(a + b)

Now look at the denominator

9x - 9y = 9(x -y)

There are a lot of possible answers.

Mine would be to multiply 3/5 * 10/9

\dfrac{3}{5}*\dfrac{10}{9} = \dfrac{30}{45} = \dfrac{2}{3}

so

(10a + 10b)/(9x - 9y) = 2/3
