1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:

2. Pass the number 50 from the right member to the left member. Then you obtain:

x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:

x=(-b±√(b^2-4ac))/2a

</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50

4. Therefore, when you simplify, the result is:

-10</span><span>±5</span>√2 (It is the last option).<span>

</span>

Here , the ratio <em><u>UV:</u></em><em><u>VW</u></em> and <em><u>UT:TS</u></em> will be in proportion , so ;

${:\implies \quad \sf \dfrac{UV}{VW}=\dfrac{UT}{TS}}$

Putting the given values ;

${:\implies \quad \sf \dfrac{18}{36}=\dfrac{UT}{24}}$

${:\implies \quad \sf UT=\dfrac{1}{2}\times 24}$

${:\implies \quad \bf \therefore \quad \underline{\underline{UT=12 \:\: units}}}$

Can someone find x for these questions

Maurinko [17]

Answer:

8, 36, -12

Step-by-step explanation:

Q2

41 = 8x - 23

8x = 41 + 23

8x = 64

x = 8

Q4

11 = x/2 - 7

22 = x - 14

22 + 14 = x

x = 36

Q6

3(x - 8) = -60

x - 8 = -20

x = -12

If a probability distribution is 5/12, 1/6, 1/3, x, what is the value of x

wolverine [178]

The probabilities of all possible outcomes in a distribution must sum to 1.

$\dfrac5{12}+\dfrac16+\dfrac13+x=1\implies x=\dfrac1{12}$

Andries get grandfather get offered to give him a gift of 50% of the amount of money he saved in one year. And Ray saved $120. H

sertanlavr [38]

Answer:

$60

Step-by-step explanation:

The savings of Andries is $120 and his grandfather offered that he would give 50% of the amount he saved.

50% is actually just half of a given amount. So the short way to do this is just half the saving of Andries.

$\dfrac{\$120}{2} = \$60$

You can also think of it this way:

$50\%=\dfrac{50}{100}$

So we multiply that to the amount saved to solve for what is 50% of 120.

$\$120\times\dfrac{50}{100} = \dfrac{\$6000}{100}=\$60.00$
