1- A
(frac{x+9+14+12+5}{5}=10 → x + 40 = 50 → x = 50 – 40 = 10)
2- D
The difference of the file added, and the file deleted is:
( 652,159 – 599,986 = 52,173)
(937,036 + 52,173 = 989,209)
3- B
5 days 19 hours 35 minutes (- 3) days 12 hours 22 minutes (=) 2 days 7 hours 13 minutes
4- A
Formula of triangle area =( frac{1}{2} (base × height))
Since the angles are (45-45-90), then this is an isosceles triangle, meaning that the base and height of the triangle are equal.
Triangle area = (frac{1}{2})
(base × height) = (frac{1}{2} (2 × 2) = 2)
5- C
(50%) of (84 = 42)
(84 + 42= 126)
6- C
(2(6h, 3) = 30)
7- D
The area of the circle is (16π) cm(^2), then, its diameter is 8cm.
(area space of space a space circle space = πr^2=16π→r^2=16→r=4)
Radius of the circle is 4 and diameter is twice of it, 8.
One side of the square equals the diameter of the circle. Then:
( Area space of space square space = side×side=8×8=64)
8- D
(x^frac{1}{2}) equals to the root of (x). Then:
(10+x^frac{1}{2}=14→10+sqrt x=14→sqrt x=4→x=16)
(x = 16) and (15 × x) equals: (15 × 16 = 240)
9- D
When a point is reflected over (x) axes, the ((y)) coordinate of that point changes to ((-y)) while its (x) coordinate remains the same.
(C (7, 9) → C’ (7, -9))
10- D
A set of ordered pairs represents (y) as a function of (x) if:
( x_1=x_2→y_1=y_2 )
In choice A: ((3, -2)) and ((3, 7)) are ordered pairs with same (x )and different (y), therefore (y) isn’t a function of (x).
In choice B:( (4, 2)) and( (4, 7) )are ordered pairs with same (x )and different (y), therefore( y) isn’t a function of (x).
In choice C: ((5, 7)) and( (5, 18)) are ordered pairs with same( x) and different( y), therefore (y) isn’t a function of (x).
