Given:
The bases of trapezoid measuring 4 m and 12 m.
To find:
The median of the trapezoid.
Solution:
The median of the trapezoid is the average of its bases.
The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:
Therefore, the correct option is C.
Answer:
-1
Step-by-step explanation:
This all comes down to the substitution. I am assuming that (4x2) is meant to be 4x^2 so I will solve as that.
4(-2)^2 = 4(4) = 16
4(-2) = - 8
-2(3)^2 = -2(9) = -18
3(3) = 9
16-8-18+9= -1
77/5=99/x
77x=5*99
77x=495
x=495/77
x=6.4
she needs to study 6.4 hrs to get 99
Answer:
a = - 1, b = - 3, c = - 5, d = - 6
Step-by-step explanation:
Substitute the appropriate values of x into the equation and evaluate
x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a
x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b
x = 1 : y = - 1 - 4 = - 5 → c
x = 2 : y = - 2 - 4 = - 6 → d
Answer:
2011
Step-by-step explanation:
Here is the formula.
A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
