Answer:
10.38 in
Step-by-step explanation:
Long side would be opposite to 60°.
Since, side opposite to 60° is root 3 upon 2 times of hypotenuse.
Answer:
The question is asking for the perimeter. There are three ways to answer this depending on the assumptions though so I'll let you choose.
Assumptions are basically the different scenarios
1st scenario being the trim covers the carpet and the tile, they'd need 48m of trim (12+12+4+8+8+4)
2nd scenario in which the trim covers the carpet but not the tiled area, they'd need 44m of trim (12+12+4+8)
3rd scenario where the trim only covers the the tiled area, 4m of trim
(just 4 since the tile only touches 4m of the wall)
Hope this helps!
Step-by-step explanation:
trim is just the perimeter since it covers the base of the wall
-10(x-7) -3x
= -10x + 70 - 3x
= -13x + 70
The answr is A
Nope!
Let's say there are 14 boys and 15 girls in a math class. We can use the ratio 14:15 to find out how many boys and girls would be in a class triple the size.
There are many more ways to write a ratio than part to whole. I hope I helped! :)
Answer:
a=1
Step-by-step explanation:
2a + 3(a + 1) = 8
Distribute
2a +3a +3 = 8
Combine like terms
5a +3 =8
Subtract 3 from each side
5a+3-3=8-3
5a = 5
Divide by 5
5a/5 = 5/5
a=1
