Answer:

2,265.60 ft/hr

Step-by-step explanation:

168ft/6min = 28ft/min * 60min= 1,680ft/hr

472ft/12.5min= 37.76ft/min * 60min= 2,265.60ft/hr

Answer:

(4, - 2 )

Step-by-step explanation:

Given the 2 equations

x + y = 2 → (1)

x - y = 6 → (2)

Adding the 2 equations term by term will eliminate the term in y, that is

(x + x) + (y - y) = (2 + 6)

2x = 8 ( divide both sides by 2 )

x = 4

Substitute x = 4 in either of the 2 equations and solve for y

Substituting in (1)

4 + y = 2 ( subtract 4 from both sides )

y = - 2

Solution is (4, - 2 )

A coffee franchise is opening a new store. The company estimates that there is a 70% chance the store will have a profit of $50,
aivan3 [116]

Step-by-step explanation:

The expected value is the sum of each outcome times its probability.

E = (0.70)(50000) + (0.05)(0) + (0.25)(-3500)

E = 34125

The store is expected to gain $34,125.

a chinchilla weighs 2 pounds its weight is 1/8 the weight of a koala write an expression and solve it to show how much the koala
Wittaler [7]
So you can say that the weight of a koala here can be x.

So x * 1/8 = 2

2 being the chinchilla's weight and the 1/8 coming from the fact that the chinchilla weighs 1/8 of the weight of the koala.

So you can just divide both sides by 1/8 first.

x * 1/8 = 2

/ 1/8       / 1/8

Or,

x *1/8 * 8/1 = 2 * 8/1

x = 16

So the koala weighs 16 pounds.
