Answer:
9cm
Step-by-step explanation:
3/12 is equal to 1/4 ratio between the size of the window and the building.
Apply that ratio to the the 36 centimeters to get 36/4 which is equal to 9 centimeters.
Answer:
0.136m
Step-by-step explanation:
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 20= 3/h. You divide cos(20) by 3 and you get the answer of 0.13602m.
Answer:
2/5
Step-by-step explanation:
First you want to find the least common denominator, which in this case would be 15. If you multiply 2/5 by 3, you get 6/15 which is less than 7/15
35w + 150 = s

Answer:
Small boxes: 8
Large boxes: 11
Step-by-step explanation:
number of small boxes = x
number of large boxes = y
weight of boxes is represented by:
50x + 80y = 1280
Number of boxes is represented by:
x + y = 19
First, we'll solve for x in terms of y:
x = 19-y
Then we'll substitute that into the weight equation
50(19-y) + 80y = 1280
950 - 50y + 80y = 1280
30y = 330
y = 11
Now drop that numerical value into the number of boxes equation, and we'll get
x + 11 = 19
x = 8
Check the math in the weight equation:
50(8) + 80(11) =
400 + 880 = 1280
