Answer:
14yd
Step-by-step explanation:
Scale of the model:
1in to 2yd
This suggest that for every 1in on the model, the actual distance is 2yd.
So;
A model 7in wide will actually be:
1in to 2yd
7in will be 7 x 2 = 14yd
The angles are B and C.
The three angles add up to 180º
A=80º
B
C
A+B+C=180º
80º+B+C=180º
B+C=180º-80º
B+C=100º (1)
The ratio between A and B is 7/13 ; therefore:
B/C=7/13 ⇒B=7C/13 (2)
With the equations (1) and (2), we make a system of equations:
B+C=100
B=7C/13
We can solve this system of equations by substitution method:
7C/13 + C=100
least common multiple=13
7C+13C=1300
20C=1300
C=1300/20
C=65
B=7C/13
B=7*65/13
B=455/13
B=35º
Answer: The measures of those two angles are 65º and 35º.
Answer:
-1/8 > x
Step-by-step explanation:
Rewrite the equation to -1 > 8x, so -1/8 > x
Dot -1/8 on the number line, and everything on the left of that point( if right is positive ) is x .
He would sell 57 papers in 3 hours.
38÷2= 19
So 19 papers in one hour.
19×3= 57
Hope this helps! :)
