Your answer would be .166
6 repeating
Answer:
Step-by-step explanation:
if x is the size of the width, then that means that the length would be x + 12.
now area is = to L * W
that means that (x) * (x+12) = Area
so multiply it out,
you get that x^2 + 12x = Area
Since we know the length (L) to width (W) ratio is 3 to 1, we can put the ratio in the form of a fraction and solve for the unknown length (L’).
Therefore we have L/W = 3/1 = L’/33
Moving the width of 33 to the other side of the equation, we have 3/1 * 33 = L’
99/1 = L’
99 = L’
Therefore the length L’ should be 99cm if the width is 33cm.
Let me know if you have any questions.
Answer:
a) 2x+2x+x+x+x=42
b) x=6
c) 6 cm, 6cm, 6cm, 12cm, 12cm
Step-by-step explanation:
First think of how you'll get perimeter. Since in the question it says you add all of the sides to get the perimeter, you write the variables being added together and equal it to 42. Next, you add all of the x's together, which you would get 7x=42. Then, you divide 7x and 42 by 7, giving you x=6. Finally, you plug in 6 into the x's, making sure to multiply the ones that are 2(6) into 12. To check if this is true, add the sides together and make sure you get 42.
We must use a certain formula to find the circumference. The formula for circumference of a circle is:
C = 2 * pi × r
Substitute:
C = 3.14 × 6.1 × 2
C = 38.303
Round to the nearest tenth:
38.3.
ANSWER:
The circumference of the circle is about 38.3 centimetres.
