Answer:
3. 16.67
4. 25
Step-by-step explanation:
3. x+2÷8=14/6 (similar triangles have corresponding proportional sides)
x+2=(7×8)/3
x=56/3-6/3 (LCM)
x= 50/3
4. 27/72= (-4+4x)/64
3/2= (-1+x)/16
-1+x=24
x=24+1
I think a partial variation
Answer:
Step-by-step explanation:
Area = 35*100*2 + 50*100*2 + 50*35*2
= 7000 + 10000 + 3500
= 20500 cm2
Answer:
<em><u>1 and 5</u></em>
Step-by-step explanation:
The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:

Insert the radius:

Simplify pi:

Simplify multiplication:

The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:

Add the perimeter of the circle and the square together:

Now see which of the options gives you the perimeter:
