How much of the 8% solution should we use to make 100g of a 3% solution?
sp2606 [1]
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3  of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.

Which statements are true about ΔJKL and ΔLMN? Select all that apply.
svp [43]

Answer:

A. ΔJKL and ΔLMN have only one pair of angles that are congruent

C. ΔJKL has angles that measure 50^o,60^o,70^o

Step-by-step explanation:

step 1

Find the value of x

we know that

m\angle KLJ=m\angle MLN ----> by vertical angles

substitute the given values

(6x-2)^o=(5x+10)^o

solve for x

6x-5x=10+2\\x=12

step 2

Find the measure of the interior angles of triangle JKL

we have

m\angle KLJ=(6(12)-2)=70^o

m\angle KJL=(5(12))=60^o

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle JKL=180^o-130^o=50^o

therefore

Triangle JKL has angles that measure 50^o,60^o,70^o

step 3

Find the measure of the interior angles of triangle LMN

we have

m\angle MLN=(5(12)+10)=70^o

m\angle LMN=(6(12)-7)=65^o

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle LNM=180^o-135^o=45^o

Triangle LMN has angles that measure 45^o,65^o,70^o

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

The corresponding angles of triangle JKL and LMN are not congruent

therefore

The triangles are not similar

<u><em>Verify each statement</em></u>

Part a) ΔJKL and ΔLMN have only one pair of angles that are congruent

The statement is true (see the explanation)

Part b) ΔJKL and ΔLMN have two pairs of angles that are congruent

The statement is false

Because have only one pair of angles that are congruent

Part c) ΔJKL has angles that measure 50^o,60^o,70^o

The statement is true  (see the explanation)

Part d) ΔLMN has angles that measure 50^o,60^o,70^o

The statement is false

Because, Triangle LMN has angles that measure 45^o,65^o,70^o

Part e) ΔJKL and ΔLMN are similar

The statement is false

Because, the corresponding angles are not congruent
