Answer:

kk so imma help you with this because this is like reealllyy easy soo basically all you have to do is use the multichoice and multiply is with the number example here is 2 then subtract/multiply/add/divide with the other number which is for this problem is 2. And right now our main goal is for it to equal 22 because both sides are equal. So if we multiplied 2 with 7 it would equal 14 and 14-2=12 which not be true. So you would have to the same thing for every one of the choices till it fits. And for this problem it would be 12 because 12x2=24 and 24-2=22. lol i hope you understand this whole thing annywwaaayyss hope this helped imma go finish my test now.

There is 1000cm3 of aluminum available to cast a trophy that will be in the shape of a right square pyramid. Is this enough alum

stealth61 [152]

The 1000 cubic centimeters of aluminium is enough for aluminium a trophy that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.

Step-by-step explanation:

The given is,

Volume of aluminium available is 1000 cubic centimeters

Shape of trophy is right square pyramid

Trophy has a base edge of 10 cm and slant height of 13 cm

Step:1

Formula for volume of right square pyramid,

$Volume, V = a^{2}\frac{h}{3}$ .....................................(1)

Where, a - Base edge value

h - Height of pyramid

From given,

a = 10 cm

h = 13 cm

Equation (1) becomes,

$= 10^{2}(\frac{13}{3} )$

$= (100)(4.333)$

$= 433.33 cm^{3}$

Volume of trophy = 433.33 cubic centimeters

Compare with the volume of available aluminium and volume of right square pyramid,

$Volume of available aluminium > Volume of right square pyramid$

$1000 cm^{3} > 433.33 cm^{3}$

So, the given volume of aluminium is enough to make right square pyramid shaped trophy.

Result:

The 1000 cubic centimeters of aluminium is enough for aluminium a trophy that will be in the shape of a right square pyramid and has a base edge of 10 cm and a slant height of 13 cm.

Here goes my 3 question

Anastaziya [24]

It's a because the form for being proportional is
ab=k
or
a/b=k
4/6=k
4 times 6=k

then 5 times 7=k
false so

so there is no ratio so the answer is A
