HELP ASAP PLZ PLZ PLZ I GIVE BRAINLIEST

Yuki888 [10]

Answer:

Step-by-step explanation:

We can see that the base TA is 4, and the second base RS is 2. We can see that the height is 4. The area of a trapezoid is:

$A=\frac{h(b_1+b_2)}{2}$

Using this, we can substitute, and get:

$A=\frac{4\cdot(2+4)}{2} = \frac{24}{2} = 12$

Hope it helps!!

Answer:

$\frac{ {x}^{2} }{(x - 1)} = \frac{ {x}^{2}(x + 1) }{( {x}^{2} - 1)} \\ = \frac{( {x}^{3} + {x}^{2}) }{( {x}^{2} - 1) }$

Solve the equation. Show work for partial credit.

Natali5045456 [20]

Answer:

x = $\frac{8}{5}$

Step-by-step explanation:

Given

$\frac{5}{x}$ + $\frac{3}{x}$ = 5 ← combine terms on left side

$\frac{8}{x}$ = 5 ( multiply both sides by x )

8 = 5x ( divide both sides by 5 )

$\frac{8}{5}$ = x

what is the ratio for the volumes of two similar spheres given that the ratio of their radii is 4:7 A.)343:64 B.)49:16 C.)16:49

quester [9]

Answer:

Volume of the similar sphere be 64 :343 .

Option (D) is correct.

Step-by-step explanation:

Formula

$Volume\ of\ a sphere = \frac{4}{3}\pi r^{3}$

As given

The volumes of two similar spheres given that the ratio of their radii is 4:7 .

Let us assume that the x be the scalar multiple of the radi .

Radius of first sphere = 4x

Radius of second sphere = 7x

Putting the values in the formula

$Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 4x\times 4x\times 4x$

$Volume\ of\ first\ sphere = \frac{4}{3}\pi\times 64x^{3}$

$Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 7x\times 7x\times 7x$

$Volume\ of\ second\ sphere = \frac{4}{3}\pi\times 343x^{3}$

Thus

$\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{\frac{4\pi\times 64x^{3}}{3}}{\frac{4\pi\times 343x^{3}}{3}}$

$\frac{Volume\ of\ first\ sphere}{Volume\ of\ second\ sphere} = \frac{64}{343}$

Therefore the ratio of the volume of the similar sphere be 64 :343 .

Option (D) is correct .
