What is d equal to in 3pi d =12pi

Alexxx [7]

Pi is commonly written as 3.14 even though it has an infinite decimal point value. 3pi multiplied by d (which d equaling 12pi) is our expression. Pi = 3.14. 3 x 3.14 = 9.42. 12 x 3.14 = 37.68. The expression is now 9.42 multiplied by 37.68. 9.42 x 37.68 = 353.8456.

4. How fast was a driver going if the car left skid marks that were 32 feet long on dry concrete? (The coefficient of friction i

Monica [59]

Answer:

$v_{o} \approx 31.247\,mph$

Step-by-step explanation:

The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:

$a = \mu_{k}\cdot g$

$a = (1.02)\cdot \left(32.174\,\frac{ft}{s^{2}} \right)$

$a = 32.817\,\frac{ft}{s^{2}}$

The initial speed is computed from the following kinematic expression:

$v^{2} = v_{o}^{2} - 2\cdot a \cdot \Delta s$

$v_{o} = \sqrt{v^{2}+2\cdot a\cdot \Delta s}$

$v_{o} = \sqrt{\left(0\,\frac{ft}{s} \right)^{2}+2\cdot \left(32.817\,\frac{ft}{s^{2}} \right)\cdot (32\,ft)}$

$v_{o}\approx 45.829\,\frac{ft}{s}$

$v_{o} \approx 31.247\,mph$

Help please, stuck on this one!

Answer:

AFCE = 30

P+Q = 11

Step-by-step explanation:

From the picture, you can see the figure can be decomposed into two identical large triangles with area 20, and 4 identical longer ones, that have to cover the remaining area 40, thus 10 each.

From that you can count the area.

Second puzzle is just trial and error.
