Volume ratio is 686/250 = 2.74
Area ratio is
                                                                                                250 yd^3
radii?  First solid has vol 250 yd^3 = (4/3)*pi*r^3; find r^3  = --------------
                                                                                               (4/3)*pi

Then r^3 = 187.5 yd^3, and r = 5.724 yd

Second solid has vol 686 yd^3 ....  Please find the radius R using precisely the same method.

Then calculate the ratio of the surface areas of the 2 solids:

Solid 1 surface area        4*pi* R^2
----------------------------- = ---------------    where R is the radius of the larger 
Solid 2 surface area        4*pi*r^2        solid and r is the radius of the smaller
                                          
                                           R^2
This ratio comes out to   ----------
                                            r^2

Scale factor?  Obviously one solid is larger than the other.  We have to figure out by how much, by comparing volumes.  Actually, we've already done that (see above).  We could also determine how much larger R is than r.  That, too, would give us the scale factor.

Greater. This is because 1/2 x 10/10 = 10/20. 11>10

What is the answer to this
deff fn [24]
So the first column is if a serving is 36 so all you have to do is divide all the different ingredient amounts by three and that will tell you the answer for the serving of 12 row because 12 * 3 = 36

and for the 24 row just multiply all the numbers you get in the 12 row and that will be the answer cause 12 * 2 = 24 

then what ever numbers you get on the 12 serving column just divide those by 12 and that will tell you how much you get for one serving and that will help you solve for the 60 one and the 300 one all you have to do it times the numbers by 60 and then 300

Help plz ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!
Yakvenalex [24]

Answer:

-2

Step-by-step explanation:

Let's solve your equation step-by-step.

−(3v+1)+7(6v+6)=−37

Step 1: Simplify both sides of the equation.

−(3v+1)+7(6v+6)=−37

−3v+−1+(7)(6v)+(7)(6)=−37(Distribute)

−3v+−1+42v+42=−37

(−3v+42v)+(−1+42)=−37(Combine Like Terms)

39v+41=−37

39v+41=−37

Step 2: Subtract 41 from both sides.

39v+41−41=−37−41

39v=−78

Step 3: Divide both sides by 39.

39v

39

=

−78

39

v=−2

Answer:

v=−2

A middle school took all of its 6th grade students on a field trip to see a symphony. The students filled 300 seats, which was 1
prisoha [69]

Answer:

3,000

Step-by-step explanation:

Basically, there are 300 seats filled which is 10%

100% is 10x10

300=10%

multiply both sides by 10

300x10=3000 and 10x10=100

therefore, the total number of seats is 3000 since 100% represents the whole thing.

Hope this was helpful!
