Answer:
B
Step-by-step explanation:
This is a distance-rate-time problem, so we need to use the equation: 
, where d is the distance, r is the rate, and t is the time.
Here, we know that the total distance is 150, so d = 150. Also, we are given that Sergio's rate is 60 mph, so r = 60. Put these in:
d = rt
150 = 60t
To solve for t, we divide both sides by 60. Because we are dividing and not multiplying, we know that B is the only one that is incorrect.
Hope this helps!
His sum should be more than 48.
I know because if you throw away the decimal pieces
and just add up the whole numbers 45 and 3 ,
right there you would have 48 . So when you include
the decimal pieces, they'll make it even bigger.
Step-by-step explanation:
let's first convert feet to inches
4 ft = 48 inches ( width )
6.5 ft = 78 inches ( length )
12.5 ft = 150 inches ( height )
each cube is 1/4 x 1/4 x 1/4
x-axis ( length )
78 ÷ 1/4 = 78 x 4 = 312 cubes
y-axis ( width )
48 x 4 = 192 cubes
z-axis ( height )
150 x 4 = 600 cubes
the total number of cubes fit in the closet is :
312 x 192 x 600 = 35,942,400 cubes
-24/4=-6
x^-7x+6=0
(x-6)(x-1)=0
x=6 or x=1
