So since its a right triangle, we can use the pythagorean theorem, which is 
. Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:
Since √13 can't be further simplified, that is your final answer.
Answer:
210
Step-by-step explanation:
1.(Subtract both sides) we know that 14 - 14 = 0 But now you turn ZERO Into an X because anytime you subtract and get a ZERO IT WOULD BE X SO NOW YOU WILL TRY TO FIND/SOLVE X' I HOPE THIS HELPED/HELPS! (: I GOT 15 AS THE ANSWER BY SUBTRACTING 224-14 AND THEN I GOT 210 AND DIVIDED BY 14. BUT SINCE THERE IS NO X=15 ,It would be 210 because of subtraction.
Answer:
0.93333333333
Step-by-step explanation:
-4/5 = 0.8
-7/6 = 1.16666666667
-1.16666666667 x -0.8 = 0.93333333333
Answer:
x=4
y=-3
Step-by-step explanation:
use substitution method :
1)
7x + 8y = 4 ... (1)
3x + 2y = 6 ... (2)
2) Create the third equation by using
equation (2)
3x + 2y = 6
3x = 6-2y
x = 6-2y/3 ..... (3)
3) Substitute (3) into (1)
7(6-2y)/3 + 8y = 4
4) Solve the equation
42 - 14y /3 + 8y = 4
42 -14y+24y = 12
10y = 12-42
y = -3
5) Find value of x
x = 6-2y/3
= 6 -2(-3)/3
= 12/3
= 4
Answer:
1.619
Step-by-step explanation:
We have the formulas for the volume of the sphere and the cylinder:
Vs = (4/3) * pi * (r ^ 3)
Vc = pi * h * (r ^ 2)
Thus:
(4/3) * pi * (r ^ 3) + pi * h * (r ^ 2) = 10
Now, the formula for the surface area of the cylinder and sphere are:
As = 4 * pi * (r ^ 2)
Ac = 2 * pi * r * h + 2 * pi * r ^ 2
Using this equation for the total surface area of the solid, we can see that as "h" increases, so will the surface area. Therefore, the smallest surface area will occur at h = 0.
Thus:
(4/3) * pi * (r ^ 3) + pi * 0 * (r ^ 2) = 10
(4/3) * pi * (r ^ 3) = 10
r ^ 3 = 4 * 10 / (3 * 3.14)
r ^ 3 = 4.24
r = 1.619
so the radius is 1.619
