Determining Ratios in a Mixture

Mathematics

Answer:

1:4

Step-by-step explanation:

Let X be the quantity of 30% acid and Y be the quantity of 5% acid.

0.3X + 0.05Y = 0.1(X+Y)

0.3X + 0.05Y = 0.1X + 0.1Y

0.3X - 0.1X = 0.1Y - 0.05Y

0.2X = 0.05Y

X/Y = 0.05/0.2

X/Y = 1/4

X:Y = 1:4

Given that ∠A≅∠B , Evelia conjectured that ∠A and ∠B are acute angles.
ivolga24 [154]
<span>A counterexample is an example which disproves a proposition.

Given that Evelia conjectured that <A and <B are acute angles. Since, <A is congruent to <B, a counterexample to the conjecture is two equal angles which are not acute angles.

</span><span>An acute angle is an angle smaller than a right angle (it is less than 90 degrees and more than 0 degrees).

Therefore, the statement that is a counterexample to Evelia's conjecture is </span><span><span>m∠A=126°</span> and <span>m∠B=126°</span></span>

Geometry math question
Ksju [112]

RE is a line, so angles RPL and EPL form a linear pair and are supplementary.

Supplementary angles are two angles whose measures add up to 180 degrees.

3z + 2z = 180

5z = 180

z = 36

m<RPL = 3z = 3 * 36 = 108

m<EPL = 2z = 2 * 36 = 72

Answer: D. 108 and 72

the variable z is directly proportional to x. when x is 15, Z has the value 0.2. What is the value of Z when x = 23
Natalka [10]

Answer:

The value of Z = 0.3066... Or 0.31.

Step-by-step explanation:

The formula of direct proportional is a=kb (where k is constant). Given that a=z=0.2 and b=x=15, equation is 0.2=15k,

k=0.2/15

k=0.0133333333333

If x is 23 then what is z?

z=0.0133333333333(23)

z=0.3066666 or 0.31
