Answer: hope this helps! have a great day!
god bless!
Step-by-step explanation:
If the last digit is even (0, 2, 4, 6, or 8) then it is divisible by 2.
Sum the digits. The result must be divisible by 3.
The last two digits form a number that is divisible by 4.
If the last digit is 0 or 5 then it is divisible by 5.
It is divisible by 2 and by 3 then it is divisible by 6.
Sum the digits. The result must be divisible by 9.
If the ones digit is 0 the the number is divisible by 10
Answer: Option B, x ≥ 121
Step-by-step explanation:
We start with the inequality:
√x ≥ 11.
First, we can square each side of the inequality, to get:
(√x)^2 ≥ 11^2
And we know that:
√(x^2) = (√x)^2 = x
Then:
x ≥ 11^2
x ≥ 121
So we only need to have x equal or larger than 121.
The correct option is B.
Answer: Divide the room into two figures (a rectangle and a trapezoid), then find the area of both figures and add them in order to calculate the area of the dining room.
Step-by-step explanation:
Divide the room into two figures: a rectangle and a trapezoid (as you can observe in the picture attached).
You need to find the area of the trapezoid and the area of the rectangle and then add them. This sum will be the area of the dining room.
First, you need to remember that:
1. The area of a rectangle can be calculated with this formula:
![A_r=lw](https://tex.z-dn.net/?f=A_r%3Dlw)
Where "l" is the lenght and "w" is the width of the rectangle.
2. The following formula is used to calculate the area of a trapezoid:
![A_t=h(\frac{B+b}{2} )](https://tex.z-dn.net/?f=A_t%3Dh%28%5Cfrac%7BB%2Bb%7D%7B2%7D%20%29)
Where "B" and "b" are the bases of the trapezoid and "h" is the height of the trapezoid.
Therefore, the area of the dining room will be:
.![A_{room}=A_r+A_t\\\\A_{room}=lw+h(\frac{B+b}{2} )](https://tex.z-dn.net/?f=A_%7Broom%7D%3DA_r%2BA_t%5C%5C%5C%5CA_%7Broom%7D%3Dlw%2Bh%28%5Cfrac%7BB%2Bb%7D%7B2%7D%20%29)
