41.848/3.4=12.308
The actual building is 12.306 times larger than the model.
Answer:
AS IT IS RIGHT ANGLE .
THEREFORE, 1 ANGLE =90°
A=55°,
LET LAST ANGLE BE Y.
THEREFORE, Y=90-55=35°
RATIO OF A:Y=55:35=11/7
RATIO OF ANÔTHER SIDE :X=11:7
HYPOTENOUES=8
THEREFORE8^2=11X^2+7X^2
64=121X^2+49X
Answer:
36 pencils
Step-by-step explanation:
Let h and p represent the number of highlighters and the number of pencils, respectively.
Then h + p = 45, and h = 45 - p.
Tom paid a total of $30 for these supplies, with ($2/highligher)(h) + ($0.333/pencil) adding up to that amount.
substituting 45 - p for h in 2h + 0.333p = 30, we get:
2(45 - p) + 0.333p = 30, or
90 - 2p + 0.333p = 30
Combine the constants: 60 = 2p - 0.333p, or 60 = 1.667p
Then p = 60/1.667 = 35.9928, or 36.
Tom bought 36 pencils for $12, and 45-36, or 9, highlighters for $18, for a total purchase of $30. This shows that these calculations are correct.
Answer:
D, 20:30
Step-by-step explanation:
At first glance, this does not seem like the correct ratio. But I'll spare you a long intro and get into it:
20:30: Divide both of them by 10
=2:3
2 x 12:3 x 12
24:36
Hope this helps!
