5x + 75 > = 600 (thats greater then or equal)
Answer:
I think it's
2 HgO (s) → 2 Hg (l) + O2 (g)
Step-by-step explanation:
This is an oxidation-reduction (redox) reaction:
2 HgII + 4 e- → 2 Hg0
(reduction)
2 O-II - 4 e- → 2 O0
(oxidation)
Answer:
D. More students preferred band or chorus than those that preferred football.
Step-by-step explanation:
I can easily tell D is the answer because 16+14=30. This means 30% liked band or chorus and 26% liked football.

Answer:
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Step-by-step explanation:
x = larger acute angle
y = smaller acute angle
Recall:
A right angle measures 90°
Sum of angles in a triangle = 180°
y = 1/4x
Hence :
90 + x + y = 180
x + y = 180 - 90
x + y = 90 - - - (1)
y = 1/4x - - - - (2)
Put y = 1/4x in (1)
x + 1/4x = 90
1.25x = 90
x = 90 / 1.25
x = 72
x + y = 90
72 + y = 90
y = 90 - 72
y = 18
Answer: B. 84 in²
Step-by-step explanation:
Divide the area into two regions: a rectangle and a trapezoid (depicted in the attached photo).
Find the area of the rectangle:
Area of a rectangle=length*width
Area of rectangle=(5 in)( 10 in)
Area of rectangle=50 in²
Next, calculate the area of the trapezoid:
Area of trapezoid=
h=10 in-6 in
h=4 in
Area of trapezoid=
Area of trapezoid=
Area of trapezoid=
Area of trapezoid=
Add the area of the trapezoid to the area of the rectangle to find the total area: 50 in²+34 in²=84 in²
