Because ABCD is a rectangle, the length of CD is 12 cm.
We need to determine the length of DE. If we can do that, then the sum of the lengths of CD and DE represents the unknown: the length of CE.
To find the length of CE, we have to "solve" the upper triangle.
Here's an outline of what to do:
1. Show that BC=AD and find the length.
2. Note that angle CAD is 60 degrees. Why?
3. Note that angle EAD is 30 degrees. Why?
4. Find the length of ED
5. Add ED and DC, that is, ED + 12 cm. This is your answer.
Please ask questions if need be.
This may be wrong but this is how id do it.
110.25 + 55.45 = 165.7
165.7 x 4.5 = 745.65 g of brown sugar
It is 1/3
3:3 =1
9:3 = 3
make sure that the top and bottom numbers divide with the same number :)
Answer:
Answer : 52 girls
Step-by-step explanation:
Your ratio of boys to girls is 3:4
Set up a fractional proportion and cross multiply
3/4 = 39/x
cross multiply
3x = 4(39)
3x = 156
x = 156/3
x = 52 girls
