The answer is 31/40
because first you got cane both of the fraction to the same denominator.
72/80 + 70/80
Add 72+70=142.
142/80 change it to an mixed number and it will be 1 31/40 in simplest form.
Answer: It's the third one
Step-by-step explanation:
C is at the bottom end so make C there and then you’ll have ABC
Answer:
Perimeter of the picture and frame = 38.4inches
Area of the picture and frame = 92.16inches²
Step-by-step explanation:
A square frame is made up of 4 different pieces. The shape of each piece = Rectangle
The perimeter of the rectangle = 24
Perimeter of the rectangle = 24 inches
The perimeter of a rectangle = 2L + 2W
The Width of a Rectangle is always on her than the length hence.
24 = 2L + 2W
24 = 2( L + W)
24/2 = L + W
12 = L + W
Because the width is always longer than the length
W > L
Width of wooden frame = 4 × Length
Therefore;
4 × L = W
Which gives
L + W = 12 inches
4 × L + L = 12 inches
L×(4 + 1)
= 5L = 12 inches
L = 12/5 = 2.4 inches
W = 4 × L = 4 × 12/5
W = 48/5 = 9.6 inches
Side length of wooden frame, L =9.6
The perimeter of the picture frame = 4 × L= 4 × 9.6= 38.4 inches
The area of the picture frame = L²
= L × L
= 9.6 × 9.6 = 92.16inches².
The way you can tell if a function is linear or non-linear is if the rate of change is constant. Here you can tell it isn't the whole time.
-3 to -1 is +2
-1 to 0 is +2
0 to 1 is +1 (Here is where the rate of change changes, making it non-linear.)
But just in case, let's check the y-values.
-5 to -1 is +4
-1 to 1 is +2 (Again, here is where you can tell)
Hope this helps!
