HELP MEEEEE PLEASEEEEEE
Sindrei [870]

Answer:

x=16\dfrac{28}{37}\\ \\y=5\dfrac{1}{3}\\ \\z=7.5

Step-by-step explanation:

The diagram shows three paralel lines which divide the large triangle into three similar triangles.

By Thales theorem,

\dfrac{5}{z}=\dfrac{y}{8}=\dfrac{2}{3}

Then

\dfrac{5}{z}=\dfrac{2}{3}\Rightarrow 2z=15,\ z=7.5\\ \\\dfrac{y}{8}=\dfrac{2}{3}\Rightarrow 3y=16,\ y=\dfrac{16}{3}=5\dfrac{1}{3}

From the similarity of triangles,

\dfrac{x}{20}=\dfrac{z+8}{z+8+3}\\ \\\dfrac{x}{20}=\dfrac{7.5+8}{7.5+8+3}\\ \\\dfrac{x}{20}=\dfrac{15.5}{18.5}\\ \\x=20\cdot \dfrac{155}{185}=20\cdot \dfrac{31}{37}=\dfrac{620}{37}=16\dfrac{28}{37}

A scientist needs 60 liters of a 40​% acid solution. He currently has a 20 % solution and a 50 % solution. How many liters of ea
Stella [2.4K]

percent ---------------- quantity

Acid type I 60.00% ---------------- x liters

acid type II 30.00% ------ 60 - x liters

Mixture 40.00% ---------------- 60

Total 60 liters

60.00% x + 30.00% ( 60 - x ) = 40.00% * 60

60 x + 30 ( 60 - x ) = 2400


60 x + 1800 - 30 x = 2400

60 x - 30 x = 2400 - -1800

30 x = 600

/ 30

x = 20 liters 60.00% Acid type I

40 liters 30.00% acid type II

liraira [26]

Answer:

graph C

Step-by-step explanation:

Well I lik it spread out cause you get more information and you can tell how the data is aligned and not scrunched up. Since the example said that the explanatory variable (indepdent variable) is best on the X axis, only C and A are left. A is all scrunch’s up and data could be read worng, but C is nice and spread and it shows all the data and rating clearly

Suppose that two​ players, R and​ C, write down letters of the alphabet. If both write vowels or both write​ consonants, then th
vladimir2022 [97]

Answer:

-0.075

Step-by-step explanation:

[Player R, Player C] cases & outcomes :-

  • (Vowel, Vowel) = (0,0)
  • (Consonant, Consonant) = (0,0)
  • (Vowel, Consonant) = (6,-6)
  • (Consonant, Vowel) = (-5,5)
  • Prob (R chooses consonant) = 75% = 0.75
  • Prob (R chooses vowel) = 1 - 0.75 = 0.25
  • Prob (C chooses vowel) = 30% = 0.30
  • Prob (C chooses consonant) = 1 - 0.30 = 0.70

Average Loss of R = Expected value of : he choses consonant & C choses vowel; he chooses vowel & C choses consonant

= (0.75)(0.30)(-5) + (0.25)(0.70)(6)

-1.125 + 1.05

= -0.075
