Step-by-step explanation:
Since we have given that
Number of hour Marco practiced the piano on Monday is given by
Number of hours Marco practiced the piano on Tuesday is given by
1) For Adding :
Total number of hours he practiced on both Monday and Tuesday will be
2) For Subtraction,
Number of hour he practiced more on Tuesday than on Monday will be
They got $80 from the first twenty tickets. Then they got $136 from the other tickets. 136/2=68. 20+68=88
They sold 88 raffle tickets.
Answer:
Perimeter of shape,which is a convex polygon i.e quadrilateral = 24.2 in
Sides are 8.3 in, 8.3 in, 3.8 in ,and length of fourth side be x in.
As , Perimeter = Sum of all sides
→ 24.2 = 8.3 + 8.3 + 3.8 + x
→ 24.2 = 16.6 +3.8 + x
→ 24.2 = 20 .4 + x
Keeping like terms on one side, of equation
→ 24.2 - 20.4 = x
→ 3.8 = x
→ x = 3.8
So, length of fourth side = 3.8 in
The given shape is definately either a Parallelogram or a kite.
Since the shape is a square, it has 90° angles.
if cut in half, it creates a 45-45-90 triangle.
using this, you can use the ratio of 1:sqrt2 to find x. so the ratio would be x:6 to 1:sqrt2.
divide 6 by sqrt2 to find x, and then rationalize for it to become 6sqrt2/2, which would simplify even further to 3sqrt2
