Answer:
No
Step-by-step explanation:
2/3 in decimal is .6 repeating
1/4 in decimal is 0.25
therefore we cannot conclude that 2/3 is equal to 1/4
The length and width of the rectangle is 11 in and 8 in respectively.
Step-by-step explanation:
Given,
The width of a rectangle is 3 in less than the length.
The area of each congruent right angle triangle = 44 in²
To find the length and width of the rectangle.
Formula
The area of a triangle with b base and h as height =
bh
Now,
Let, the width = x and the length = x+3.
Here, for the triangle, width will be its base and length will be its height.
According to the problem,
×(x+3)×x = 44
or, 
or,
or,
+(11-8)x-88 = 0
or,
+11x-8x-88 =0
or, x(x+11)-8(x+11) = 0
or, (x+11)(x-8) = 0
So, x = 8 ( x≠-11, the length or width could no be negative)
Hence,
Width = 8 in and length = 8+3 = 11 in
Answer:B: 133.75$
Step-by-step explanation:
35 + 40 + 50= 125$
The total sales tax is 7%
We can put this into decimal form 7/100= 0.07
Because we want to just add 7% of the value back on we can also add 1 to that number
1.07
125 x 1.07 = 133.75
