Answer:
Let,x be the total number of examinees:-
We have,
Hence,required number of examinees = 360 .
Answer:
X = 0, Y = -2
Step-by-step explanation:
5(2x + 6y = -12)
2(5x - 5y = 10)
10x + 30y = -60
10x - 10y = 20
40y = -80
y = -2
x = (10 + (-2)5) / 5
x = 0
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 .
The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48 .
The factors that are common to 40 and 48 are 1, 2, 4, and 8 .
The greatest one is <u><em>8</em></u> .
Answer:
Step-by-step explanation:
Given : The ice cream cone is a half sphere(hemisphere) sitting on top of the cone.
To Find : volume of the toy Ice cream cone.
Solution :
Refer the figure
We can see that radius of cone = radius of half sphere(hemisphere) = 6cm
Height of cone = 8 cm
Volume of the toy Ice cream cone = VOLUME OF CONE + VOLUME OF HEMISPHERE .
First calculate the volume of cone .
Formula of volume of cone :
Where r = radius of cone and h = height of cone and
So, the volume of ice cream cone :
⇒
⇒
⇒
⇒
⇒
Thus the volume of cone is
Now formula of volume of sphere :
r = radius = 6 cm
Thus the volume of the hemisphere is
Now , Since we know that
Volume of the toy Ice cream cone = VOLUME OF CONE + VOLUME OF HEMISPHERE .
⇒ 301.44 +452.16
⇒
Hence, The volume of the toy Ice cream cone is
-20.85+15.50=-5.35,
basically, you still own the bank 5.50 dollars
