Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
Answer:
1) a body of air with horizontally uniform temperature, humidity, and pressure.
2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.
3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.
4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.
5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.

Answer:
A = 88 m^2
Step-by-step explanation:
The area of this parallelogram is found by
A = b*h
The base is equal to 4+7 and the height is 8
A = 11 *8
A = 88 m^2
Answer:
The graph of h(x) is shown below.
Step-by-step explanation:
The given function is
The general form of sine function is
Where, a is amplitude, b is period, c is phase shift and d is vertical shift.
So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.
It means the minimum value of function is -7 and maximum value is 7.
Put x=0 in the given function.
Put 
in the given function.
Put 
in the given function.
Therefore the points on the function are (0,0), 
.
The graph of function is shown below.
The final product is -24(2) which equals - 48.
