Answer:

$\sqrt{16 \times9 \times 3 \: \: equals \:4 \times 3 \times \sqrt{3that \: eauas \: 12 \sqrt{3} } }$

Step-by-step explanation:

Square root of 16 ×9×3= square root of 432

square root of 16 =4

square root of 9 =3

That will equal 4×3× square root of 3 which finally equals to 12 square root of 3.

Answer: $12\sqrt{3}$

On a keyboard, you would write 12*sqrt(3)

==============================================

Explanation:

Find the prime factorization of 432 to get

432 = 2^4*3^3

That allows us to do the following steps

$\sqrt{432} = \sqrt{2^4*3^3}\\\\\sqrt{432} = \sqrt{2^2*2^2*3^2*3^1}\\\\\sqrt{432} = \sqrt{2^2}*\sqrt{2^2}*\sqrt{3^2}*\sqrt{3^1}\\\\\sqrt{432} = 2*2*3*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\$

------------------

Or you could do something like this

$\sqrt{432} = \sqrt{144*3}\\\\\sqrt{432} = \sqrt{144}*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\$

In triangle abc, if A=120 degrees, a=8 and b=3, then angle B=

CaHeK987 [17]

The angle of B is $\angle B=19^{\circ}$

Explanation:

It is given that $\angle A=120^{\circ}$ and $a=8, b=3$

To determine the $\angle B$ , let us use the law of sine formula.

Thus, we have,

$\frac{Sin A}{a} =\frac{Sin B}{b}$

Substituting the values in the formula, we have,

$\frac{Sin 120}{8} =\frac{Sin B}{3}$

Multiplying both sides by 3,we get,

$\frac{3(0.866)}{8} ={Sin B}$

Simplifying and dividing, we get,

$0.32475=Sin B$

Multiplying both sides by $\sin ^{-1}$ , we get,

$\sin ^{-1}(0.32475)=B$

Thus, $B=18.95^{\circ}=19^{\circ}$

Hence, The angle of B is $\angle B=19^{\circ}$

John bought 3 pineapples and 2 watermelons for $8.50. Sue bought 2 pineapples and 4 watermelons for $13.00. Write and show a sys

AleksAgata [21]

As per your question, total cost of watermelon should end with either 5(for odd quantity) or 0(for even quantity).

If the quantity of watermelon is odd, then the total cost value of pineapple should end with 3 and this is not possible when the cost of pineapple is ₹7.

So let's come to conclusion that the count(quantity) of watermelon should be any one of 0, 2, 4, 6.

If count of watermelon is 6: It will cost ₹30 and for remaining ₹8, we can buy 1 pineapple but still ₹1 will not be utilised. So 1 pineapple is not possible

If count of watermelon is 4: It will cost ₹20 and for remaining ₹18, we can buy 2 pineapple with ₹4 not being utilised. So 2 pineapple is also not possible.

If count of watermelon is 2: It will cost ₹10 and for remaining ₹28, we can buy 4 pineapple with all amount being utilised. We can buy 4 pineapple along with with 2 watermelon for ₹38.

If count of watermelon is 0: It will cost you ₹0 and for remaining ₹38, we can buy 5 pineapple with ₹3 being not utilised. So 5 pineapple is also not possible.

So the answer is 4 pineapple.

A company developed the following linear model to help budget annual expenses over time. In this model, x represents the number

ollegr [7]

The only reasonable answer I could think for this is "A.<span>The company's expense budget for 2009 was $189,785."
I believe this because since x is the years after 2009 then you wouldn't times that by the expense budget for that year or any year eliminating B and C. When finding the total expense budget for this you would have to take in account the budget from 2009 so that would lead it to add 189,758. Since we are talking about after 2009 then D would be eliminated since 2008 is before 2009.
I hope this helps! Good luck!</span><span>
