4 pupils can eat 12 because if you times 6 by 2 you get 12, so if you do the same to the other side then you'll get the answer 4 (2X2=4)
The triangles are congruent due to SAS
Answer:
a=3.33m/s^2
Step-by-step explanation:
F=ma
a=F/m
To find Force you have to subtract the gravitational force by the air force
F=600-400
F=200N
m=60kg
Plug in the values:
a=200N/60kg
a=3.33m/s^2
Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=
×l
=![\frac{l}{10}](https://tex.z-dn.net/?f=%5Cfrac%7Bl%7D%7B10%7D)
hence area of original frame=A=length×width
=![\frac{l^{2} }{10}](https://tex.z-dn.net/?f=%5Cfrac%7Bl%5E%7B2%7D%20%7D%7B10%7D)
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+
×l
=
×l
width of new frame==![\frac{l}{10}](https://tex.z-dn.net/?f=%5Cfrac%7Bl%7D%7B10%7D)
area of new frame=length×width
=![\frac{11l^{2} }{100}](https://tex.z-dn.net/?f=%5Cfrac%7B11l%5E%7B2%7D%20%7D%7B100%7D)
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%
Answer:
The top of the cake is 25.12 in²
Step-by-step explanation:
Hello!
So you are dealing with a circumference question! And because the diameter is 2x the radius, we know the radius is actually 4.
Lets write out the circumference formula and use that to help us.
c = 2
x r
pi is 3.14....
But lets use 3.14
c = 2(3.14) x 4
Plus this into a calculator and we get 25.12 as the answer.
