B - line graph. A line graph should be added because he wants to know how many of available apartments there were during the time of the year and line graphs are usually up and down on the info.
81,85,89 are the missing numbers
Answer:
20π square units
Step-by-step explanation:
The sector area is found using the proportion ...
sector area / circle area = sector angle / whole circle angle
Multiplying by "circle area", we get ...
sector area = (circle area)( sector angle / whole circle angle)
= (100π)(2/5π)/(2π)
= (100π)(1/5)
sector area = 20π
Since he is using 3x more flower than the original, you would multiply the 2 tsp by 3 as well
6tsp is the answer
A cuboid is a box-shaped object. It has six sides and all are perpendicular
Formula for volume is:
V=a*b*c
Formula for a surface area is:
A=2*(ab+bc+ac)
We start writting down given information:
V=40cm^3
A=100cm^2
a=2cm
Now we insert this information into formulas:
40=2*b*c
100=2*(2b+bc+2c)
Now we divide both equations by 2:
20=bc
50=2b+bc+2c
We solve first equation for b and insert it into second equation:
b=20/c
50=2*20/c+20/c*c+2c
Now we solve for c:
50=40/c+20+2c
30=40/c+2c
30c-40-2c^2=0
2c^2-30c+40=0
c^2-15c+20=0
c1=13,52
c2=1,48
We got two solutions for c so we will get two solutions for b:
b1=1,48
b2=13,52
Now we know:
a=2cm
b=1,48cm
c=13,52cm
Formula for a diagonal is:
