Answer:
C. 4yd * 3ft/yd * 12in/1ft * 2.54cm/1.in = 365.76cm
Step-by-step explanation:
First you change 4 yards into feet (By multiplying the 4 yard by 3 ft/1yd)
then you convert 12 feet into inches (By multiplying the 12 feet by 12in/1ft)
after you convert 144 inches to cm (By multiplying the 144 in by 2.54 cm/1in)
you’ll have the value in cm. Which is 365.76.
You multiply
4*6=24 and 7*7=49
you get 24/49
You have to distribute 3x+1 over the other parentheses
3x(2x^2 +4x-3) + 1• ( 2x^2 +4x-3)=
6x^3 +12x^2 -9x + 2x^2 +4x-3 =
Combine like terms
6x^3 +14x^2 -5x -3
The original value was <span>£720.
720 x .15 (15%) = 108
720 + 108 = 828 </span>
Answer:
Perimeter of the final star = 40 cm²
Step-by-step Explanation:
The perimeter of the six-pointed star is the sum of the sides of the 6 equilateral triangles that form a boundary around the star.
1 triangular tiles gas a perimeter of 10cm.
Only 2 out of the 3 equal sides of each of the 6 equilateral triangles form the boundary of the final star.
Therefore, perimeter of the final star = ⅔ of the total perimeter of 6 triangular tiles
= ⅔ of (10*6)
= ⅔*60
= 2*20
Perimeter of the final star = 40 cm²
