If you would like to know what is the value of 54 - 4 * a^2 + 3 * b^3 when a = -2 and b = 4, you can calculate this using the following steps:
54 - 4 * a^2 + 3 * b^3 = 54 - 4 * (-2)^2 + 3 * 4^3 = 54 - 4 * 4 + 3 * 64 = 54 - 16 + 192 = 230
If you would like to know what is the value of 54 - 4 * a^2 - 3 * b^3 when a = -2 and b = 4, you can calculate this using the following steps:
54 - 4 * a^2 - 3 * b^3 = 54 - 4 * (-2)^2 - 3 * 4^3 = 54 - 4 * 4 - 3 * 64 = 54 - 16 - 192 = -154
Red Cards = 10
Other Cards (Black + Blue) = 10+20 = 30
So, the ratio would be: 10/30 = 1/3
So, your final answer is 1/3
Hope this helps!
Answer:
(0,5) (1,0)
Step-by-step explanation:
Place your first dot on the 5 (0,5) of the y-axis (The one that is vertical) from there count down the line one value at a time until you have counted DOWN 5 times. Go to the right once and place another point there (1,0). Then draw a straight line that connects those two points.
Answer:
4
Step-by-step explanation:
a + 12/3 = 8
a + 4 = 8
a = 8 - 4
a = 4
If we want to know what percent of a number A is of another
number B, then all we have to do is to simply divide number A by number B. Then
either we move the decimal place of the answer two places to the right or
multiply the answer with 100, either method results in the same number.
So the percent of tested people who had an allergic reaction
to the new lotion is:
percent people = (15 / 200) * 100
percent people = 0.075 * 100
percent people = 7.5%
Therefore 7.5% of the people had allergic reaction.
