U will be using a scale factor of 2...because if u multiply the original dimensions by 2, you will get the new dimensions of ur drawing

16ft= 192 in
8ft= 96 in

192/36= 96/16 = 6

Your drawing is 1/6 of the actual billboard

A hoop, a uniform solid cylinder, a spherical shell, and a uniform solid sphere are released from rest at the top of an incline.

Serjik [45]

Answer:

Step-by-step explanation:

Given

Hoop, Uniform Solid Cylinder, Spherical shell and a uniform Solid sphere released from Rest from same height

Suppose they have same mass and radius

time Period is given by

$t=\sqrt{\frac{2h}{a}}$ ,where h=height of release

a=acceleration

$a=\frac{g\sin \theta }{1+\frac{I}{mr^2}}$

Where I=moment of inertia

a for hoop

$a=\frac{g\sin \theta }{1+\frac{mr^2}{mr^2}}$

$a=\frac{g\sin \theta }{2}$

a for Uniform solid cylinder

$a=\frac{g\sin \theta }{1+\frac{mr^2}{2mr^2}}$

$a=\frac{2g\sin \theta }{3}$

a for spherical shell

$a=\frac{g\sin \theta }{1+\frac{2mr^2}{3mr^2}}$

$a=\frac{3g\sin \theta }{5}$

a for Uniform Solid

$a=\frac{g\sin \theta }{1+\frac{2mr^2}{5mr^2}}$

$a=\frac{5g\sin \theta }{7}$

time taken will be inversely proportional to the square root of acceleration

$t_1=k\sqrt{2}=1.414k$

$t_2=k\sqrt{\frac{3}{2}}=1.224k$

$t_3=k\sqrt{\frac{5}{3}}=1.2909k$

$t_4=k\sqrt{\frac{7}{5}}=1.183k$

thus first one to reach is Solid Sphere

second is Uniform solid cylinder

third is Spherical Shell

Fourth is hoop

If a neutral atom gains an electron, what is its charge?

DENIUS [597]

C. Negative because since the neutral atom stands at 0 and positive ions are 1+ and electrons are negative if it gains the electron ( negative ) it will become negative.

At the honda dealership,45% of all cars sold include a sunroof. If this sold 247 cars last week, about how many would you expect

sertanlavr [38]

It is 45% of 247 move the the decimal on the 45% two places to the right, then you should get .45. Of means multiply so .45*247 should get you the answer of 111.15 that's how you find the percent of this number. If you round the answer you would get 111 so about 111cars had a sunroof

The first term of an arithmetic sequence is 9 and the common difference is –2. What is the seventh term? A. 0 B. –3 C. –1 D. –5

faust18 [17]

Answer:

The answer is D. -5.

Step-by-step explanation:

The sequence begins with 9. The sequence is reduced by 2 each step, for seven steps. Results of the seven negative steps:

7 * -2 = -14.

The difference is:

9 - 14 = -5
