Answer:
60%
Step-by-step explanation:
45 pieces out of 75 pieces are chocolate
45/75
Divide: 45/75 = 0.6
To get percentage from a decimal, move the decimal point to the right two place values
0.6 => 60%
60% of his candy are chocolate
Answer:
it is because 20 + 20 is 40 and then 40 - 20 = 20
Suppose x is sold, $280 each , and y is the total financial cost. The first equation in the system is then certainly y = 280x.
The vertex form <span>y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.
So, plug the values in.
</span><span>11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052
y-</span><span>24,000 = -0.052(x-500)^2
y= </span><span>-0.052(x-500)^2 + 24,000
This is the second equation in the system.
The answer is then A, which contain the system </span><span>of equations which can be used to determine must be sold for the company to make a profit.</span>
3x + x = 1044
4x = 1044 - divide both sides by four
x = 261
coffee table - $261
couch - $783
Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio
