Answer: 18900
Step-by-step explanation:
Given the question:
In 2001, the Guinness Book of World Records recognized a breakfast which served 18,941 people as the largest ever cooked. Which number below shows 18,941 rounded to 3 significant digits?
18,941 rounded to 3 significant figures
To round to 3 significant figures, the first 3 numbers are kept intact, then the subsequent number is rounded up to 1 if up to or greater than 5 and added to the third figure. If less than 5, all subsequent numbers are rounded down to 0
Hence,
18,941 = 18900 (because 4 is less than 5, 4 and all subsequent numbers are rounded down to 0).
Answer:
0.2
Step-by-step explanation:
Let the length and width of the square board be x cm, when 4 cm are cut of from the corner, the dimensions of the box will be:'
length=(x-8) cm
width=(x-8) cm
height=x cm
thus the volume will be:
4(x-8)(x-8)=144
4(x^2-16x+64)=144
this can be written into:
x^2-16x^2+64=36
solving the above gives us:
x=2 or x=14
when x=2, the dimensions will be negative. Thus we take x=14 cm, the original dimensions are 14 cm by 14 cm

Answer:
26.13
Step-by-step explanation:
Area of the two triangles:
divide by 2 to find the other side of the triangle and the radius
this is just one triangle multiply by two to find both sides together
(6)(2) = 12 this is the area of both triangles
Area of the half-circle:
A = 
this is the formula for a whole circle so we have to then divide by 2
=
= 28.3
= 
=
Add the area of the triangle with the area of the half-circle:
12 + 14.13 = 26.13
Hope this helps!!
