Answer: 20%
Step-by-step explanation:
The 150 students in the marching band and 30 of the students play the trumpet. To get the percentage of students that play the trumpet, we divide 30 by 150 and then multiply by 100. This can be written as:
= 30/150 × 100
= 0.2 × 100
= 20%
The percentage of students that play the trumpet is 20%
Answer:
x=9
y=3
Step-by-step explanation:
since all three sides of an equlateral triangle are equal:
3x+y=30 then y=30-3x
4x-2y=30
4x-2(30-3x)=30
4x-60+6x=30
10x=90
x=9
3x+y=4x-2y
x=3y
y=3
The slope is zero because the line is not moving
<h2>Question:- Area of the given diagram</h2>
<h2>Answer :- </h2>
Divide the diagram as shown in attachment.
Now first calculate the area of the rectangle having side 1 and 12
So area = length ×breadth
Area = 1× 12 = 12 unit²
Now find the Area of the remaining triangle with sides 12,13,5 units
So

Now put the value as -> base= 5 and height= 12

Now add both areas for your answer

Answer:
Below in bold.
Step-by-step explanation:
x can have any real value - the domain is (-∞, ∞).
f(x) cannot be 0 or negative, no matter how negative x is, - the range is (0, ∞)
