Answer:

  a. FG ≈ 6.983 cm

  b. FH = 13.16 cm

Step-by-step explanation:

<h3>a)</h3>

Corresponding sides of similar triangles are proportional. This means ...

  FG/GH = CD/DE

  FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values

  FG ≈ 6.983 cm

__

<h3>b)</h3>

And ...

  FH/GH = CE/DE

  FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)

  FH = 13.16 cm

__

<em>Additional comment</em>

Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).

In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JL=25 and JM=5, find KM.
d1i1m1o1n [39]

Answer:

KM = 15

Step-by-step explanation:

From the diagram, ΔJKL and ΔJKM are similar to each other because they share the same angle J and they are both right angle triangle. Therefore they are similar by AA property.

Since JL=25 and JM=5, JM = JL + JM= 25 + 5 = 30

Since ΔJKL and ΔJKM are similar to each other, therefore:

\frac{JK}{JL}=\frac{JM}{JK}\\  Substituting:\\\frac{JK}{30}=\frac{5}{JK}\\JK^2=150\\JK=\sqrt{150}\\ \\From\ hypotenuse:\\JK^2=JM^2+KM^2\\Substituting:\\(\sqrt{150} )^2=5^2+KM^2\\150=25+KM^2\\KM^2=150-25=125\\KM=\sqrt{125}\\ KM=15

If you need to put 1 teaspoon in a 10 gallon tank how many teaspoons for a 8 gallon tank
alex41 [277]

Answer:

0.8\ teaspoon

Step-by-step explanation:

Let

x ----> the number of teaspoon

y ---> the number of gallons

we know that

\frac{x}{y} =\frac{1}{10} ---> equation A

For y=8 gal

substitute the value of y in the equation A

so

\frac{x}{8} =\frac{1}{10}

solve for x

x=\frac{1}{10}(8)

x=0.8\ teaspoon

How many grams of solute are needed to prepare 2oz of 8% iodine solutions​
dimaraw [331]

Answer:

  4.732 grams

Step-by-step explanation:

2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.

For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.

  About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.

_____

We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.
