Solve the equation for the specified variable. T= BA-9, for B What does b=

NARA [144]

9514 1404 393

Answer:

$B=\dfrac{T+9}{A}$

Step-by-step explanation:

Add 9 to both sides of the equation, and divide by the coefficient of B.

T = BA -9

T +9 = BA

(T +9)/A = B

We can rewrite that with B on the left:

B = (T +9)/A

Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cub

Troyanec [42]

Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

$r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}$

Which means that option E is correct.

The volume of a cube of side length l is given by:

$V = l^3$

For Cube A, the volume is of 9 cubic inches, hence:

$l_a^3 = 9$

$l_a = \sqrt[3]{9}$

$l_a = 9^{\frac{1}{3}}$

$l_a = 3^{\frac{2}{3}}$

For Cube B, the volume is of 5 cubic inches, hence:

$l_b^3 = 5$

$l_b = \sqrt[3]{5}$

$l_b = 5^{\frac{1}{3}}$

Then, the ratio is:

$r = \frac{l_a}{l_b} = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}$

Answer the question above

Strike441 [17]

Answer:

Step-by-step explanation:

Here, we want to get the hypotenuse side

The hypotenuse represents the longest side

it is the side that faces the largest angle in a right triangle

The largest angle in a right triangle is the right angle which is the angle 90

It is like the square at a corner at the vertex C

The side facing it here is the the length AB (BA)

Which of the triangles are right triangles? Please be 100% sure about your answers. I will mark Brainliest!

Kisachek [45]

1 is wrong because the measurements do not work for the pythagorean theorem.
3 is wrong because using the pythagorean theorem with those measurements would not work.
4 is wrong because the only way that 4 would work is if the hypotenuse was 3√2 not 3√3

The correct answer is 2 because that is the only one that actually works with the pythagoran theorem.

√41^2 = 41
5^2 + 4^2 = 25 + 16 = 41
41 = 41
