C + d = 2(c - d)
c = 9
9 + d = 2(9 - d)
9 + d = 18 - 2d
d + 2d = 18 - 9
3d = 9
d = 9/3
d = 3 <=== daira is 3 when carl is 9 years old and older then she
if carl is 9 years old and is younger then she ...I dont really understand this question....carl is 9 and daira is 3......possibly...their is a difference of 6 years in their ages....so if carl is 9 and younger then she, the daira is 6 years older ?? making her 9 + 6 = 15....not sure about this one ....the whole question throws me off
Answer:
Subtract 1/3 from 2/3 dont forget to add the variable h!
1/3h + 11 = 8
-11 -11
1/3h = -3
Now we multiply by 3 on both sides
H = -9
Answer: 26
Step-by-step explain:
the whole triangle = 180
the angle with a square is a right angle so its 90 degrees
180 - 90 - 62 = 26
Hope this helps✨✨

Answer:
First blank =
Second blank =
Third blank =
Step-by-step explanation:
We are given,
The argument to explain the derivation of the formula for the volume of a cone.
According to the explanation, we have,
First blank: It represents the area of the base of the cylinder.
Since, the base of the cylinder is a circle.
And, area of the circle =
Thus, the first blank =
Second blank: It represents the number by which volume of the cylinder is multiplied to obtain the volume of the cone.
Since, we know,
of Volume of cylinder is given by volume of the cone.
Hence, the second blank =
Third blank: It represents the formula for the volume of the cone.
As, Volume of the cone =
Thus, third blank =
