What is the EDGE LENGTH of a cube with VOLUME 27/64 cubic units?

Mathematics
1 answer:
Effectus [21]3 years ago
8 0

Step-by-step explanation:

Let edge length of cube be x units.

volume \: of \: cube =  \frac{27}{64}  \\  \\  \therefore \:  {x}^{3}  = \frac{27}{64}  \\  \\ \therefore \:  {x}^{3}  = \frac{ {3}^{3} }{ {4}^{3} }  \\  \\ \therefore \:  {x}^{3}  = (\frac{ {3}}{ {4} } )^{3} \\  \\  \therefore \:  {x} = \frac{ {3}}{ {4} }  \\  \\ \therefore \:  {x} =0.75 \:  {unit}

Hence, length of edge of cube = 0.75 units

Alex runs on the track at school each weekday morning. If he runs 5.9 miles each day, about how much does he run every month?
Lisa [10]
Now, since we know that 5.9 is the amount of miles per day, we need to determine how many miles per month.

Usually, there are 20 days...because of no weekdays

Multiply.

5.9 * 20 = 118

Final answer:- He runs 118 miles per month.

Write the equation of the line perpendicular to + = that passes through (−,−). Write your answer in slope-intercept form.
Ad libitum [116K]

Answer:

y = 0.25x - 5

Step-by-step explanation:

Given line is 4x + y = 3

or y = -4x + 3

Comparing this with slope-intercept form y = mx + c :

slope of this line is -4

Product of slopes of perpendicular lines = -1

⇒ slope of a line perpendicular to this is \frac{-1}{-4} = \frac{1}{4} = 0.25

This line also passes through the point (-4,-6)

The equation of a line having slope m and passing through a point (h,k) is

y - k = m(x - h)

⇒ equation of line perpendicular to given line is y - (-6) = 0.25×{x - (-4)}

⇒ y + 6 = 0.25×(x + 4)

⇒ y + 6 = 0.25x + 1

⇒ <u>y = 0.25x - 5</u>

This is in the slope-intercept form y = mx + c with slope m = 0.25 and y-intercept (0,-5)
