What is the value of m in the figure below? If necessary,round your answer to the nearest tenth of a unit
bogdanovich [222]

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

Can someone please show me the steps to solving this problem please? Many thanks!
Soloha48 [4]

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

1\;L = 1000\; mL\\\\30\;L=30 \times 1000\; mL=30,000\;mL\\\\

"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.

x=\frac{30000}{350}

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

\frac{30000}{350} \approx 86 \; bottles

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!
