Answer:
D
Step-by-step explanation:
It turns out from similar triangles, that 7/BD = BD / 18. Use triangles ABD and BDC to show this relationship. Solving this equation will give you BD
BD^2 = 7*18
BD^2 = 126 Just leave it in this form. Do your rounding at the end.
Because triangle BDC is a right angle triangle, use the Pythagorean Theorem to solve for m
m^2 = BD^2 + 7^2
m^2 = 126 + 49
m^2 = 175 Take the square root of both sides.
sqrt(m^2) = sqrt(175)
m = 13.22
so the answer is D
Answer:

Step-by-step explanation:
g
Step 1: Assign variable for the unknown that we need to find.
Let x be the number of 350 ml bottles that you should bring from the supply room.
Step 2: Use the statement given to write a mathematical equation.
Given: 30 liter drum of fertilizer
Convert the liters to milliliters

"The owner of the plant nursery where you work tells you to fill 350 milliliter bottles from a 30 liter drum of fertilizer" means we need to find how many 350 ml are there in 30,000 ml.

Step 3: Simplify and round up to the next whole number.

Conclusion:
<u>Eighty Six </u>bottles with a capacity of 350 milliliter you should bring from the supply room to fill from a 30 liter drum of fertilizer!
Step-by-step explanation:
step 1. 42 represents 35% of the birds.
step 2. 42/.35 = all of the birds counted.
step 3. 42/.35 = 120.
step 4. There are 120 total.
