Answer:

D. dA/dt = 4h dh/dt in²/sec

Step-by-step explanation:

Given:

A = wh

w = 2h

Substitute:

A = 2h²

Take derivative with respect to time:

dA/dt = 4h dh/dt

dA/dt has units of in²/sec.

Help plsss!! I’d rlly appreciate it :]

The volume of the Apple iPad Mini 2 is 12.561 in³.

The new volume of the  Pear-Apple is  24.53 in³.

The new volume of the  Pear-Apple is 5.3in³.

The scale factor to have a volume that is half that of the iPad Mini is 0.79.

The scale factor to have a volume that is double that of the iPad Mini is 1.26

<h3 /><h3>What is the volume of the Apple iPad Mini 2?</h3>

Volume = length x width x height

7.9 x 5.30 x 0.30 = 12.561 in³

<h3>What is the volume after the scale factors are applied?</h3>

Dimensions after the 1.25 scale factor is applied: (1.25 x 7.9) x (1.25 x 5.30) x (1.25 x 0.3)

= 9.875 x 6.625 x0.375 = 24.53 in³

Dimensions after the 0.75 scale factor is applied: (0.75 x 7.9) x (0.75 x 5.30) x (0.75 x 0.3)

= 5.925 x 3.975 x 0.225 = 5.3in³

Scale factor to have a volume that is double that of the iPad Mini : 2^{1/3} = 1.26

Scale factor to have a volume that is half that of the iPad Mini : 0.5^{1/3} = 0.79

Given that the two triangles are similar, solve for x if AU = 20x + 108, UB = 273, BC = 703, UV = 444, AV = 372 and AC = 589.
Damm [24]
The answer:
<span>the two triangles are similar
in addition, the line UV is parallel to line BC, so we can use the theorem of Thales for proving the following ratios:

AV /AC = AU/ AB= UV/ BC
372/589=20x +80  / AB = 444 / 703

</span>so we get    (372/589) AB - 80 =  20x, and x = ( (372/589) AB - 80  ) / 20

exact value of x depends on the value of AB

How do i find the area
RideAnS [48]
Multiply the height and base of the triangle, then divide by 2. To find the area of the semi-circle, you must do this formula. 3.14 x Diameter × 1/2

Answer : 96 + 25.12 = 121.12cm
