Answer:
its A and C , Obtuse and Isosceles triangle.
Step-by-step explanation:
It's A because it's obtuse ( triangle which have measurement between 90 and 180)
Not B because Scalene triangle have three different side but the two sides are same show by the equilateral symbol.
It's C because Isosceles triangle have two sides of equal length that we can see with the equilateral symbol.
Not D because Equilateral triangle have three sides of same length but on this triangle only two sides are same.
Not E because right angle have measurement of 90 degree.

Answer:
65 ft by 39 ft
Step-by-step explanation:
Let x ft be the length of each part and y ft be the width of each part. The total perimeter of all 5 parts is
The length of the large rectangle is 5y ft and the width of the large rectangle is x, so the total area is
From the first equation,
Substitute it into the area expression:
Find the derivative:
Equate it to 0:
Then
Answer:
54 seconds
Step-by-step explanation:
Wanda's walking rate = 3 ft/s
Wanda's head start = 27 s
Dave's walking rate= 4.5 ft/s
Let 't' be time after Dave started walking
The distance walked by Wanda and Dave, respectively, as a function of 't' are given by:
The instant 't' at which Dave catches up to Wanda (both distances walked are equal) is:
Answer:
12 pieces
Step-by-step explanation:
Since on Thursday Glenn and Ben each ate an eight, then total they ate 2*1/8=2/8=¼
¼ of 24 pieces is equivalent to
¼*24=6 pieces
The number of pieces that remain would be 24-6=18 pieces
The one third of leftover ate rhe next day will be equivalent to
⅓ of 18
⅓*18=6 pieces
Remaining pieces next day will be 18-6=12 pieces
Therefore, only 12 pieces out of 24 original pieces remain the following day.
