The next time the stations will play the song at the same time would be at 4:12 P.M. because 18×4=72 and 24×3=72 and this is the first number that they share.

A sound wave travels through iron at a rate of 5120 m/s. At what rate does the sound wave travel in km/h
marissa [1.9K]
<span>When converting a number with meters per second to a value with kilometers per second they best way to perform this operation is by using dimensional analysis or the factor label method. You would set up the equation starting with 5120 m/s times 1 km / 1000 m times 3600 s / 1 hr. It would look like this: (5120 m/ 1 s) x (1 km / 1000 m) x (3600 s / 1 hr) Your next step would be multiplying all the top numbers (numerators) together 5120 x 1 x 3600 = 18,432,000 Now multiple on the bottom numbers (denominators) together 1 x 1000 x 1 = 1000 Now you can divide the top product by the bottom product. 18,432,000 / 1000 = 18,432 km/hr is your final answer.</span>

If 2x^2+5x-12 = (2x-3)(x+4), which equation(s) should be solved to find the roots of 2x^2+5x-12=0? Check all that apply.
Fynjy0 [20]

ANSWER

2x-3=0

and

x+4=0

EXPLANATION

Given that:

2 {x}^{2}  + 5x - 12 = (2x - 3)(x + 4)

Then to find roots of

2 {x}^{2}  + 5x - 12 = 0

is the same as finding the roots of

(2x - 3)(x + 4) = 0

By the zero product property, we must have either,

2x - 3 = 0 \: or \: x + 4 = 0

Hence the equations that must be solved to find the roots are:

2x-3=0

and

x+4=0

A sculpture is shaped like a sphere with 4 cones attached to it. Several dimensions of the sculpture, in feet, are shown in the
suter [353]

volume of the center sphere = 4/3*PI*r^3

r = 3 ( given in the picture)

 so 4/3 * 3.14 *3^3 = 113.04 cubic feet

 volume of 1 cone: pi *r^2 *h/3

r = 3 and h=3 ( given in the picture)

so 3.14 * 3^2 * 3/3 = 28.26 cubic feet

 there are 4 cones so 28.26* 4 = 113.04 cubic feet


113.04 + 113.04 = 226.08 cubic feet

 rounded to nearest cubic foot = 226 cubic feet
