If the ratio of the surface areas of two similar geometrical solids is given by 121:36, what is the

BigorU [14]

Answer:

1331:216

Step-by-step explanation:

Given the ratio of the lengths of two similar solids as a:b

The ratio of the surface areas = $a^2:b^2$

The ratio of the volume = $a^3:b^3$

We are given that the ratio of the surface areas of two similar geometrical solids is given by 121:36

Therefore:

$a^2:b^2=121:36\\\implies a^2:b^2=11^2:6^2\\\implies a:b=11:6$

Since the ratio of the lengths is 11:6

The ratio of their volumes = $11^3:6^3$

=1331:216

The ratio of the volume of the two similar geometrical solids is 1331:126.

The price of a technology stock was $9.74 yesterday. Today, the price fell to $9.67. Find the percentage decrease. Round your an

agasfer [191]

% change = (new value - old value)/(old value) * 100%
.. = (9.67 -9.74)/9.74 * 100%
.. = -0.07/9.74 * 100%
.. = -0.7%

The decrease is 0.7%.

Solve for the smallest value of $x$ such that $24x^2 + 17x - 20 = 0.$ Express your answer as a simplified common fraction.

Gala2k [10]

X=5/8 or x=-4/3
here is the work if needed...
24x^2+17x-20=0
Step one: Factor left side of equation.
(8x-5)(3x-4)=0
Step two: Set factor equal to 0.
8x-5=0 or 3x-4=0
x=5/8 or x=-4/3
