A blackboard has an area of 28 ft2 and a perimeter of 22 ft. What are the dimensions of the board?
2 ft by 11 ft
2 ft by 14 ft
4 ft by 7 ft
7 ft by 7 ft
Answers
Answer:
Step-by-step explanation:
A=LW, L=A/W
P=2(L+W), using L=A/W we get
P=2(A/W+W)
P=2(A+W^2)/W
PW=2A+2W^2
2W^2-PW+2A=0, given A=28 and P=22 we have
2W^2-22W+56=0
2(W^2-11W+28)=0
2(W-7)(W-4)=0
So the dimensions are 4ft by 7ft

12% of students of a class of 50 like blue
colour. How many children like blue colour?
Answers
Answer:
6 children
Step-by-step explanation:
(12*50)/100
If 12% of students of a class of 50 like blue colour, the number of children that like blue is 6
The number of students in the class = 50
12% of the total number of students like blue
Number of students that like blue colour = 12% of 50
Number of students that like blue colour = (12/100) x 50
Number of students that like blue colour = 0.12 x 50
Number of students that like blue colour = 6
Therefore, if 12% of students of a class of 50 like blue colour, the number of children that like blue is 6

In order to graph a line from an equation that is written in slope intercept form, what do you plot first, then next.
O plot (b) first, then plot 9mo to rise and run to find other points.
O just plot the (b) on the y-axis only.
O plot (b) on the X-axis, then (m) on the y-axis.
Oplot (m) first to rise and run to find other points, then plot (b)
Answers
Answer:
first answer - you plot 'b' [on the y-axis] first, then use the slope m = c/d to go d units right and then c units up (positive 'c') or down (negative 'c')
