Answer:
The percent of boys and girls that naden it to the honor roll increased by 27 percent (27%)
Step-by-step explanation:
Solution
cos (90-60)=cos (x+10)
⇒30=x+10
x=30-10
x=20.
Given parameters:
Coordinates of end points = (2, -3) and (-6,5).
Slope of line = 
Unknown:
Equation of the line with the given slope = ?
Solution:
Let us find the coordinates of the mid-point of the line given.
Since the end points are (2, -3) and (-6,5);
Midpoint;
x, y =
,
x, y =
,
= -2 , 1
The coordinate of the mid point = -2,1
Equation of a line is;
y = mx + c
x and y are the coordinates
m is the slope
c is the y intercept
We need to find c in order to fully develop our equation;
y = mx + c
y = 1 , x = -2 and m = 
So,
1 =
x (-2) + c
c = 1 +
= 
Now, the equation of the line is;
y = -2x +
Multiply through by 7,
7y = -14x + 25
The equation of the line is 7y = -14x + 25
Answer:
B

The rest of the options are possible using an atm card. but using it to deposit is not possible.
Hey there!!
Always remember -
wave length = velocity / frequency
Now substitute the values
Wave length = 10 / 4
Wave Length = 2.5 m
