find the geometric mean of 10 and 18. if the answer is not a whole number leave it in the simplest radical form

1 answer:

6 0

$a_{1} =10 \ and = a_{2} =18 \\ \\ Geometric \ is : \\ \\ a=\sqrt{a_{1}\cdot a_{2}} \\ \\a=\sqrt{10\cdot 18} =\sqrt{180} =\sqrt{36\cdot 5}=\sqrt{36}\sqrt{5}=6\sqrt{5} \approx 6 \cdot 2.24 \approx 13.44$

Use the net to find the surface area of the prism 8in 15in 17in 9in

exis [7]

Answer:

The surface area of the prism is 480 in².

Step-by-step explanation:

Given:

The prism dimensions are 8in 15in 17in and 9in.

Now, to find the surface area:

So, to get the surface area we put formula:

a=8in, b=15in, c=17in and h=9in.

Surface area = 2A+(a+b+c)h.

Whereas, $A=\sqrt{s(s-a)(s-b)(s-c)}$

And, $s=\frac{a+b+c}{2}$

Now, we find s first:

$s=\frac{a+b+c}{2}$

$s=\frac{8+15+17}{2}$

$s=\frac{40}{2}=20.$

Then, we get A :

$A=\sqrt{s(s-a)(s-b)(s-c)}$

$A=\sqrt{20(20-8)(20-15)(20-17)}$

$A=\sqrt{20(12)(5)(3)}$

On solving we get:

$A=\sqrt{3600}=60.$

Now, putting the value of A in the formula to get the surface area:

$Surface area = 2A+(a+b+c)h.$

$Surface area = 2\times 60+(8+15+17)9.$

$Surface area = 120+(40)9.$

$Surface area = 120+360.$

$Surface area = 480\ in^2.$

Therefore, the surface area of the prism is 480 in².

A general arranges his students to form a perfect square.He finds that in doing so 60 soldiers were left out if total number of

Korvikt [17]

Answer:

Step-by-step explanation:

Given that :

Number of soldiers = 8160

Number left out = 60

Result of arrangement gives a perfect square ;

Hence, the number of soldiers which makes up the arrangement will be ;

Total number of soldiers - number left out

8160 - 60 = 8100

Hence 8100 soldiers were used to form a perfect square ;

Number of soldiers in a row :

√8100 = 90

Hence, we have 90 soldiers in a row
