What is 10 times as much as 130

trapecia [35]

Step-by-step explanation:

$g(0.5) = 2 \\ \\ h(x) = g(x).f(x) \\ \therefore \: h(2) = g(2).f(2) \\ \therefore \: h(2) = 5 \times 2\\ \therefore \: h(2) = 10\\ \\ \\ j(x) = g(x) - f(x) \\ \therefore \: j(4) = g(4) - f(4) \\ \therefore \: j(4) = 9 - 8\\ \therefore \: j(4) = 1\\ \\ \\$

You and your 2 nieces bakes 27 cupcakes. This means that there were 27 cupcakes to be distributed evenly between the 3 of you. So divide 27 by 3 to get your answer.

27 ÷ 3 = 9.

This means that each of you would get 9 miniture cupcakes to take home.

<h3>What is percentage ?</h3>

Percentage is the value per hundredth.

According to the given question a survey was carried out among 120 school children looked at which type of meat they preferred. 55% said they preferred lamb,20% said they preferred chicken, 15% preferred duck and 10% turkey and we have to calculate no. of children in each category.

55% said they preferred lamb, So the no. of students i this category is

= (55/100)×120

= 66 children.

20% said they preferred chicken, So the no. of children in this category is

= (20/100)×120

= 24 children.

15% said they preferred duck, So the no. of children in this category is

= (15/100)×120

= 18 children.

10% said they preferred turkey, So the no. of children in this category is

= (10/100)×120

= 12 children.

Find the exact solutions and simplify as much as possible: 3x^2+1=6x

svetoff [14.1K]

Answer:

$\frac{3+ \sqrt{6} }{3}$ and $\frac{3- \sqrt{6} }{3}$

Step-by-step explanation:

This is a quadratic equation, so we start by rearranging its terms so we can apply the quadratic formula:

$ax^2+bx+c=0$ has two possible solutions given by:

$x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

So we rearrange the terms in the given quadratic equation bringing all terms to the left hhand side of the equal sign:

$3x^2+1=6x\\3x^2-6x+1=0$

The solutions will then be:

$x=\frac{6+/- \sqrt{36-4(3)(1)} }{2(3)}=\frac{6+/- \sqrt{36-12} }{6}=\frac{6+/- \sqrt{24} }{6}=\frac{6+/- \sqrt{4*6} }{6}=\frac{6+/- 2\sqrt{6} }{6}=\frac{3+/- \sqrt{6} }{3}$

Therefore the two possible answer are: $\frac{3+ \sqrt{6} }{3}$ and $\frac{3- \sqrt{6} }{3}$
