Step-by-step explanation:
The volume of a cube is s^3 where s is the length of a side..
So If you have 84 cubes with sides of 1/3 in the total volume is:
v=84(1/3)^3 in^3
v=84/27 in^3
v=28/9 in^3
V=3.11 in^3 (to nearest hundredth of a cubic inch)
-5x^3 + 2x^2 + 1
a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.
so in ur problem....there are 2 coefficients..-5 and 2.
** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.
** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.
okay...I am gonna shut up now :)
5 percent of 200 is 10 and 70/10 is 7. So after 7 years if your rate is anual rate
It's eather a low number or a greater number
Answer:
pic # 1 answer is B. 81 x pi
pic#3 answer is C. QC
Step-by-step explanation:
pic #1
the formula to find the area of a circle is pi x the radius to the second power
they give you the diameter. (18)
the radius is half of a diameter (d/2)
so 18/3 = 9
9 to the second power (9 x 9) = 81
so your answer is 81 x pi
pic#2
I don't much, but i do know they asking for the radius and since the radius is half the diameter of a circle then QC makes sense in my book.
hope this is helpful.
