8\% \ of \ 300= \frac{8}{100}*300= \\\\ =8*3= \boxed{24}

We can do this in 2 different ways.

The longer but often more clear way is to divide 300 by 100 to get 1% then multiply that by 8.
8( \frac{300}{100} )=24 -- therefore 8% of 300 is 24.

Alternatively we can just multiply 300 by 0.08
300*0.08=24

meriva

Answer:

15x -  {x}^{2}  =50 \\  {x }^{2}  - 15x  + 50 = 0 \\  {x}^{2} - 10x - 5x + 50 = 0 \\ x(x - 10) - 2(x - 10) = 0 \\ (x - 2)(x - 10) = 0 \\ x = 2 \: and \: x = 10

A bag contains 6 green marbles, 9 red marbles, 7 white marbles, and 3 black marbles. What is the probability of drawing a red ma
bonufazy [111]

Well if you add them all together you would get 25. You would have 9/25 red marbles. Then you would take 9 and divide it by 25 and get 0.36 and if you move the decimal over 2 places you’ll get 36%

If a line with a slope of -2 crosses the yaxis at (0,3) what is the equation of the line
Sliva [168]

Answer:

y=-2x+3

Step-by-step explanation:

Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).

So you can directly write the equation of the line in slope-intercept form [y=mx+b where "m" is the slope and "b" the y-value when x=0].

Such gives us:

y=-2x+3

Question 9 Eight wooden spheres with radii of 3 inches are packed snuggly into a cube-shaped box 12 inches on one side. The rema
kobusy [5.1K]
Answer is 823.2 cu.in.
Reason
For the sphere
We know V=4/3 TT r^3
Radius is 3
V=4/3 (3.14) 3^3
V= 4/3 (3.14) 27
V= 113.1 for each sphere
8 spheres x 113.1 = 904.8 cu.in.

For the cubed shaped box
We know v= length x width x height
V= 12 x 12 x 12
V = 1728 cu.in.

Now we take volume of box and subtract volume of spheres to get space filled by packing beads
1728 - 904.8 = 823.2 cu.in.
