There may be more than one correct answer here.

Note that 48 cubic units is equivalent to (6 units)(8 units)(1 unit). Can you think of any other 3 dimensions whose product is 48 cubic units?

Check the picture below.

so, each of the 48 unit cubes, have a volume of that much.

there are 48 of those cubes in the larger cube, so the volume of the larger cube is 48 * 1³.

What is the difference? 5/3-1/2 A. 4 B. 7 C. 7/6 D. 7/0 = undefined

Fofino [41]

The answer is: [C]:  " ⁷/₆ " .
____________________________________
Note:
____________________________________
(5/3) - (1/2) = ? ;
____________________________________
The LCD (lowest common denominator) of "2 and 3" is "6" ;

So we need to rewrite EACH fraction in the problem as a fraction with "6" in the denominator ;
____________________________
(5/3) = (?/6) ? ; (6÷3=2) ; (5/3) = (5*2)/(3*2) = 10/6 ;
____________________________
(1/2) = (?/6) ? ; (6÷2=3) ; (1/2) = (1*3)/(2*3) = 3/6 ;
____________________________
Rewrite the problem: "   (5/3) - (1/2) " ; as:
____________________________
10/6 - 3/6 ;
____________________________________________
  10/6 - 3/6 = (10 - 3) / 6 = (7/6) = 1 ⅙ .
____________________________________________
The answer is: " ⁷/₆ " ; or, write as: " 1 ⅙ " ; which corresponds to:

Answer choice: [C]: " ⁷/₆ " .

The speed of light is estimated at 186,000 miles per second rounded to the nearest thousand miles per second.

4vir4ik [10]

It was rounding to the nearest THOUSAND.

We are looking at the thousands place, keep that in mind.

Remember: everything 5 and above is rounded up, everything below 5 is rounded down.

186,789 is above 500, it is rounded to 187,000

186,899 is above 500, it is rounded to 187,000

185,990 is above 500, it is rounded to 186,000

and 185,190 is below 500, it is rounded to 185,000

Only one matches the criteria of the question:

185,990 is above 500, it is rounded to 186,000

therefore the answer is 185,990 miles per second

Have a fantastic day!

Solve for R 3 r + 4 ---------- = 5 2 r = ?

lakkis [162]

To find r, first write out the equation:
$\frac{3r+4}{2} =5$
Next, multiply both sides by 2:
$3r+4=10$
Now, subtract both sides by 4:
$3r = 6$
Divide both sides by 3:
$r=2$

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!

Which expression could be used to determine the cost of a $40 video game after a 15 percent discount?

LUCKY_DIMON [66]

Answer: The required expression is,

$ 40(0.85)

Step-by-step explanation:

Given,

The original cost of the videogame = $ 40,

Discount percentage = 15%,

So, the amount of discount = 15% of 40

= (0.15)40 ( ∵ 1% = 0.01 )

Hence, the cost of the videogame = original cost - discount

= 40 - (0.15)40

= 40 (1-0.15)

= 40(0.85)

Which is the required expression .
