Answer:
True
(1) You can prove two triangles are similar using AA similarity.
(2)If side length of similar figure have ration
then the ratio of surface areas will be:
(3)If side length of similar figure have ratio of
then perimeter will have ratio:
.
False:
(1)If side length of similar figure have ration
then the ratio of Volumes will be:
(2)If side length of similar figure have ration
then the ratio of surface area will be:
You use the distributive property and multiple everything inside of the parentheses by 2x^2 then everything in the parentheses by y to get 2x^4y-6x^3y^2+16x^2y^3. I think that’s the answer and I hope that helped!
453,193 400,000+ 50,000 +3,000+ 100 +90+ 3=453,193 so it is ten thousand 10,000=50,000
Let small cups = S
Large cups = L
They bought a total of 8 cups, so S + L = 8
Rewrite as S = 8-L (1st equation)
Then you also have
$3S + $5L = $30 (2nd equation)
Replace the S in the second equation with the first equation:
$3(8-L) + $5L = $30
Simplify:
24 - 3L + 5L = 30
Combine like terms:
24+2L = 30
Subtract 24 from both sides:
2L = 6
Divide both sides by 2:
L = 3
They bought 3 large cups
Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)
Large = 3 cups, Small = 5 cups
