We need 30 glass spheres whose TOTAL volume = 3,392.92 cubic inches.
Therefore each of the 30 spheres must have a volume of 3,392.92 / 30 =

Answer:
P(compact cars) = 4/25 or .16
Step-by-step explanation:
<em>We know that there are </em><em>13 trucks, 8 vans, and 4 compact cars.</em>
<em />
<em>Let </em><em>P </em><em>denotes the probability of an event</em>
<em />
<em>Now we are asked to find the probability of compact cars</em>
<em />
<em>Number of favorable events = number of compact cars = 4</em>
<em />
<em>total number of outcomes </em><em>= 13+8+4 = 25</em>
<em>hence, P(compact cars) = number of favorable events/total outcomes</em>
<em> =4/25 or .16</em>
Answer:
is that high school? cuz it looks like 8th or 7th grade
Answer:
Step-by-step explanation:
xy=-30
y=-30/x
x+y=-4
x-30/x=-4
x²-30=-4x
x²+4x-30=0
