Answer:
the truck will over load with 13 refrigerators and 8 pianos
Step-by-step explanation:
13 refrigerators is 2600 lbs
8 pianos is 4200 lbs
both added together is 6800 lbs
the truck can only hold 5900 so 13 refrigerators and 8 pianos is too heavy
This problem calls for calculating the unit cost in each case and then comparing the unit costs.
$1.79
---------- = $0.09/oz
20 oz
Noting that 1 lb = 16 oz,
$2.59
---------- = $0.14
18 oz
$1.79 for 20 oz is definitely the better buy (less expensive) when compared to $2.59 for 18 oz.
Answer:
48 is your answer.
Step-by-step explanation:
What you want to do is follow PEMDAS.
Parenthesis are first. You will subtract 32 and 8 to get 24.
6 x [(24)/4+2] You will then divide 24 and 4 to get 6.
6 x[6+2] you will then add 6+2 to get 8.
6 x 8 = 48 is your answer.
You can simplify the right side. Then, you need to take cube roots.
(m -4)³ = 1/(1/8) . . . rule of exponents
(m -4)³ = 8 . . . . . . .simplify
m -4 = ∛8 . . . . . . . take cube roots
m -4 = 2 . . . . . . . . use your calculator or knowledge to find ∛8
m = 6 . . . . . . . . . . add 4
The solution is m = 6.
_____
If you subtract the right side, you get a function of m that is zero when m has the right value. This graph shows that value is m = 6.
