Answer:
or 
Step-by-step explanation:
The given triangles are similar, meaning that their corresponding sides are proportional.
The length of DC (I think its D) is 15 and the length of WZ is 3. ZY is in the same place as CE (16). Make a proportional relationship where Δ→Δ:
Insert the known values:
x is the value of ZY. Solve by cross multiplying:
Divide both sides by 15:
ZY is 3.2.

Answer:Astrid needs 280 tons of wood
Step-by-step explanation:
Because:
1 ship requires 40 tons of wood=accomodates 300 sailors
We must:
2100, sailors needed to be accomodated
÷
300, sailors that can be accomodated by 1 ship that requires 40 tons of wood
=7 groups of 300 sailors that can be accomodated by 1 ship that requires 40 tons of wood.
So:
I ship that requires 40 tons of wood × the 7, groups = 280 tons of wood.
I hope this helps! Im sorry its too complicated.
Simplier:
2100 ÷ 300= 7
40 × 7= 280
For this case, we must find the lateral area of the pentagonal prism shown in the figure.
By definition:
Where:
: Is the lateral area
: It is the perimeter of the base
h: It's the height
Substituting the values we have:
Answer:
Answer:
Step-by-step explanation:
8y+14=3y+49
-3y . -3y
5y+14=49
-14 -14
5y=35 divide both sides by 5
y=7
