2 7/10 + 5/8 what is the answer

Well you first must get the fractions to have the same denominator. So you multiply 5/8 by 10 ( both top and bottom ) to get 50/80, and you multiply 7/10 by 8 to get 56/80. You ignore the whole 2 for now for it is not a fraction, and you add 56 plus 50 to get 106 and put it back over 80. 106/80, now since 106/80 is over 1 you can take 106 - 80 and get 26. 1 and 26/80 is what the two fractions add up to. Add the whole two to 1 and get 3 and 26/80 which can be simplified to 3 and 13/40.

What is the converse of r->(~q v p)

alexira [117]

Answer:

$r => (\neg q \ \lor p) \ \equiv \ q \ \land \ \neg p => \neg r$

Step-by-step explanation:

In general, remember that the converse of $a => b$ is $\neg b => \neg a$ , therefore in this case $a = r \ \ , b = \neg q \ \lor p$

so $r => (\neg q \ \lor p) \ \equiv \ q \ \land \ \neg p => \neg r$

15s^11-25s^4 factorised <br><br> plz tell me. :)

saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

$5(3s^{11}-5s^4)$

As for the literal part, you can factor $s^4$ because it's the power of s with the smallest denominator. So, we have

$5s^4(3s^7-5)$

In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected

aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Since we have given that

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

$35:14\\\\=5:2$

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.

What single decimal multiplier would you use to increase by 18% followed by a<br> 12% decrease?

ValentinkaMS [17]

Answer:

The single decimal multiplier used to increase by 18% followed by a 12% decrease is 0.21.

Step-by-step explanation:

Let 'x' be the number

As first the number has to be increased by 18%

so

Step 1: write the percentage '18%' in decimal form

18% = 0.18

Step 2: For percentage increases: add the decimal to 1

1 + 0.18 = 1.18

Step 3: Multiply the number x by the multiplier, found in Step 2

x × 1.18 = 1.18x

<u><em>NEXT WE HAVE TO DECREASE 1.18x by 12%</em></u>

Apply the same method but with a number 1.18x

Write the percentage '12%' in decimal form

12% = 0.12

For percentage decreases: subtract the decimal to 1

1 - 0.18 = 0.18

Multiply the number 1.18x by the multiplier, found in Previous step

1.18x × 0.18 = 0.21x

Therefore, the single decimal multiplier used to increase by 18% followed by a 12% decrease is 0.21.
