Caden buys 3.9 pounds of grapes that cost $1.80 per pound. Which expression
can be used to find the total cost of the grapes?
(3 x 0.9) x 1 + (3 x 0.9) x 8
(3 +0.9) X1 + (3 + 0.9) x 8
(3 x 0.9) x1 + (3 x 0.9) x 0.80
(3 +0.9) > 1 + (3 + 0.9) x 0.80

please help, thank you :)

c. 4 and 1/2 pounds is the answer! : )

1 is c

2 is a

3 is a

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
