Solving  RootIndex 3 StartRoot 8 EndRoot Superscript x we get =2^x

Step-by-step explanation:

We need to find equivalent to RootIndex 3 StartRoot 8 EndRoot Superscript x

Writing in mathematical form:

(\sqrt[3]{8})^x

Solving:

We know 8= 2x2x2= 2^3

and \sqrt[3]{x}=x^{\frac{1}{3}}

Applying these rules:

=((2^3)^{\frac{1}{3}})^x

=(2^{\frac{3}{3}})^x\\

=2^x

So, solving  RootIndex 3 StartRoot 8 EndRoot Superscript x we get =2^x

In a group of 100 students, 25 own a laptop, 40 own a mobile phone, and 35 own either a
Talja [164]

Answer:

My best answer is that the probability is 35/100 that the student chosen at random owns neither a laptop nor a mobile phone.

Step-by-step explanation:

If you go back and read the introductory passage, you will notice it says, "In a group of 100 students... 35 own either a laptop or a mobile phone, but not both." And I think the other numbers, I.E. 25 and 40, were just meant to throw us off. Therefore, I think 35/100 is the probability.

What is the area of △FGH to the nearest tenth of a square meter? The image is of a triangle GHF with base GH length 2m, FG is 2.
Gnesinka [82]
First, we are going to use the law of cosines to find the length of the line segment FH:
FH= \sqrt{2.5^{2}+2^{2}-(2)(2.5)Cos(121)}
FH= \sqrt{2.5^{2}+2^{2}-5Cos(121)}
FH=3.2

Next, we are going to use the semi-perimeter formula: s= \frac{GH+FG+FH}{2}
s= \frac{2+2.5+3.2}{2}
s= \frac{7.7}{2}
s=3.9

Now that we have the semi-perimeter of our triangle, we can find its area using Heron's formula:
A= \sqrt{s(s-GH)(s-FG)(s-FH)}
A= \sqrt{3.9(3.9-2)(3.9-2.5)(3.9-3.2)}
A= \sqrt{3.9(1.9)(1.4)(0.7)}
A=2.7m^{2}

We can conclude that the area of the triangle <span>GHF is 2.7 </span>m^{2}.

Faith is working two summer jobs, making $13 per hour lifeguarding and $12 per
Svetllana [295]

Answer:

Step-by-step explanation:

Let's call lifeguarding L and car washing W.  In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.

If she works 10 hours, that is the number of hours worked between both jobs.  Therefore, the equation for the NUMBER of hours worked is

L + W = 10.

If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W.  The MONEY she earned together by doing both those jobs is

13L + 12W = 124

There you go!
