Answer:
7
3 times ? - 11
=
? + 3
? = 7
Step-by-step explanation:
3 times 7 is 21 -11 is 10
7+3 is 10
Both equations has to make 10 so it is the answer of 7
Hope this helps :)

Answer:
Step-by-step explanation:
In this isosceles right triangle, the acute angles are equal and the side lengths have the ratios 1 : 1 : √2
y° = 90° -45° = 45°
9 : x : z = 1 : 1 : √2 = 9 : 9 : 9√2
x = 9; z = 9√2
So he has road 5.75 miles and 1/8=0.125 so i am going to estimate but 4.12 miles left to cover
Considering the ballon to be spherical
It's volume is given by 4/3(π r^3) by differentiating volume with respect to time we get rate of change of volume hence,
4πr^2(dr/dt)=600÷60=10
Substituting r=30cm
4π(30)*(30)(dr/dt)=10
dr/dt=rate of increase in bullion's radius=1/(360π)cm/s
