The cost of each pen is $50, because you spend $600 on books leaving $200 to buy FOUR pens, making it $50 per pen
Answer:
10%
Step-by-step explanation:
We know Perimeter of rectangle
= 2 (Length + Width)
If width and length are increased by 10%
New length= L + 10/100L = (1.1) L
New width = W + 10/100W = (1.1) W
Perimeter = 2 [(1.1) L + (1.1) W]
Perimeter = 2 (1.1) (L + W)
Perimeter = (2.2) (L + W)
Increase in perimeter = 2.2 (L + W) - 2 (L + W)
The increase in Perimeter = 0.2 (L + W)
Percent increase
= 0.2 (L + W)/2 (L + W) × 100
= 0.2/2 × 100
= 0.1 × 100
= 10%

Due the parentheses first so 16+4+11*2-21 then multiply 16+4+22-21 from here you can answer left to right 20+4+22-21 then 24+1=25
Answer:
A) 0.9(sin50)
Step-by-step explanation:
Since this is a right triangle, we can use
sin a = opposite side/ hypotenuse
sin 50 = x /.9
Multiply each side by .9
.9 * sin 50 = x/.9 * .9
.9 (sin 50) = x
Answers:
Median: The only median is the segment JG
Altitude: There are two altitudes. They are segment JG and KF
Angle Bisector: There is only one angle bisector and it is segment JG
--------------------------------------------------------------
Explanations:
The median is a segment that goes from a vertex to the midpoint of the opposite side. Only one segment fits this description and it is segment JG
An altitude is a segment that goes from a vertex to the opposite side, and it is perpendicular to the opposite side (perpendicular is shown with square angle markers). Two segments fit this description which are JG and KF. It is possible for a median to also be an altitude. In this case, triangle KJL is an isosceles triangle (KJ = JL)
Angle bisectors cut a given angle into two equal or congruent halves. The segment JG fits this description. It is possible for a segment to be a median, altitude, and angle bisector.
Side Note: the segment EL is neither a median, nor an altitude, nor an angle bisector.
