Answer:

Call Brian's age: x, then Sushil's age is: x + 6 and Caroline's age is: x-5

So we have: x + (x + 6) + (x-5) = 64

=> 3x +1 = 64 => x = 63/3 = 21

the youngest of them: 21-5 = 16

Answer:

16

Step-by-step explanation:

This is what others have said

I have no clue but if u think about it with no math involved it is most likely right  

This is as with 64 divided by 3 people is around 20 and and taking a few years would make since if its 16

Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.
tankabanditka [31]

Answer:

lateral area ≈ 668  m²

surface area ≈ 740 m²

Step-by-step explanation:

The lateral area of a triangular prism = perimeter of the base × height of the prism

lateral area = ph

where

p = perimeter of the base

h = height or altitude

Base edges are 8m , 9m and 12.04m and height is 23 m.

lateral area = ph

lateral area = (8 + 9 + 12.04) × 23

lateral area = 29.04 × 23

lateral area = 667.92  m²

lateral area ≈ 668 m²

Surface area

surface area = lateral area + 2B

where

B = area of it triangular bases

surface area = lateral area + 2B

surface area = 667.92   + 2(1/2 × base × height)

surface area = 667.92  + 2(1/2 × 8 × 9)

surface area = 667.92  + 2(1/2 × 72)

surface area = 667.92  + 2(36)

surface area = 667.92  + 72

surface area = 739.92  

surface area ≈ 740 m²

Brooke is flying a kite while standing 50 m from the base of a tree at the park. Her Chi is directly above the 10 m tree in the
Gelneren [198K]

Answer:

104.127 m

Step-by-step explanation

In the question instead of chi, it would be kite.

Given: Distance of Brooke from the base of tree is 50 meters.

The kite is directly above the 10 m tree in the 125 m string is fully extended.

Lets assume the height of the kite be "x".

Its making the Right angle triangle with length of string as hypotenuse, height of kite above tree.

Using Pythagorean formula:

h²= a²+b²

⇒125^{2} = 50^{2} + (x)^{2}

⇒15625 = 2500+ (x)^{2}

⇒ 15625 = 2500+ x^{2}

Subtracting both side by 2500

⇒ 13025 = x^{2}

Square rooting both side, we know√a²=a

⇒ \sqrt{13025} =x

∴ x= 114.127 meter.

Next, we know the value of x include the height of tree.

∴ Height of kite flying above tree= x-10\ m

⇒ Height of kite flying above tree= 114.127-10= 104.127\ m

Hence, the height of kite above the tree is 104.127 meters.
