Answer:

⇒√21+√18-√35-√30

Step-by-step explanation:

\frac{\sqrt{3}-\sqrt{5}  }{\sqrt{7}-\sqrt{6}  } \\\\\frac{\sqrt{3}-\sqrt{5}  }{\sqrt{7}-\sqrt{6}  }*\frac{{\sqrt{7}+\sqrt{6}  }}{{\sqrt{7}+\sqrt{6}  }} \\\\\frac{(\sqrt{3}-\sqrt{5})*(\sqrt{7}+\sqrt{6} )   }{(\sqrt{7})^{2}-(\sqrt{6})^{2}   }  } \\\\\frac{\sqrt{21}+\sqrt{18} -\sqrt{35}-\sqrt{30}   }{7-6}\\\\\sqrt{21}+\sqrt{18} -\sqrt{35}-\sqrt{30}

Answer:

<u>√21 + 3√2 - √35 - √30</u>

Step-by-step explanation:

<u>Given :-</u>

√3 - √5 / √7 - √6

<u>Solving :-</u>

= √3 - √5 (√7 + √6) / √7 - √6 (√7 + √6)

= √21 + √18 - √35 - √30 / 7 - 6

= √21 + 3√2 - √35 - √30

<u>Solution :-</u>

<u>√21 + 3√2 - √35 - √30</u>

Female III-4 is pregnant via male III-5. The owner of this breeding pair wants to know the probabilities of several possible out
faust18 [17]

Answer: the following are required for IV-3 to have condition

Explanation:

-II-4 passes an X b chromosome to III-4 (probability = 1/2).

-If III-4 has the genotype X B X b (accounted for by the above probability), then she passes an X b chromosome to IV-3 (probability = 1/2).

-III-5 passes a Y chromosome to IV-3 (probability = 1/2).

All of these requirements are needed in sequence, so you apply the product rule here, too (1/2 x 1/2 x 1/2 = 1/8).

Once the individual probabilities are known, the sum and/or product rules can be used for various combinations (both conditions, either condition, etc.).

HELP ASAP!!!!!!
WARRIOR [948]

Answer:

x=26

C = 91

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B+ C = 180

35+ 52+ 3(x+5) = 180

Distribute

35+52+3x+15 = 180

Combine like terms

102 +3x = 180

Subtract 102 from each side

102-102 +3x=180-102

3x= 78

Divide by 3

3x/3 = 78/3

x=26

Now we need to find angle C

c = 3(x+5)

C = 3(26+5)

     3(31)

     93

Can someone please help a guy out? and ASAP. i'm really tired and i've been trying to get this done for months but i cannot unde
lorasvet [3.4K]

Answer:

1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.

2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.

3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.

4) It fits perfectly

5) The data is pretty inconsistent.

6)  About 68-69 inches tall

7)About 71-72 inches wide

yeo u had my brain work after this
