Assume that y varies inversely with x. If y=7 when x=2/3, find y when x=7/3

zepelin [54]

Y=k/x
7=k/(2/3)
7=k(3/2)
times both sides by 2/3
14/3=k

y=(14/3)/x
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2

If you place a 17 foot ladder against the top of a 8 foot building how many feet will be bottom of the ladder be from the bottom

Marat540 [252]

Answer:

The distance of the bottom of the ladder be from the bottom of the building is = 15 feet

Step-by-step explanation:

Given:

Length of the ladder =17 ft

Height of the building = 8 ft

To find the length between the bottom of the ladder and the bottom of the building.

Solution:

On drawing out the situation, we find out that a right triangle is formed with the ladder being the hypotenuse and the building being a leg of the right triangle.

<em>We need to find the length of the other leg of the triangle which is the distance from the bottom of the ladder to the bottom of the building.</em>

Applying Pythagorean theorem:

$Hypotenuse^2=Leg1^2+Leg2^2$

Plugging in values in feet from the given data.

$17^2=Leg1^2+8^2$

Simplifying.

$289=Leg1^2+64$

Subtracting both sides by 64.

$289-64=Leg1^2+64-64$

$225=Leg1^2$

Taking square root both sides.

$\sqrt{225}=\sqrt{Leg1^2}$

$15=Leg1$

∴ $Leg1=15\ ft$

Thus, distance of the bottom of the ladder be from the bottom of the building is = 15 feet

Flauer [41]

Answer:

Step-by-step explanation:

Split up the polygon into three parts. The first rectangle will be 264 and the two small squares are 16, but since there is two we multiply them by 2, making it 32.

An aquarium has a base in the shape of a trapezoid. The base is 100

Nat2105 [25]

Answer:

$Volume = 210L$

Step-by-step explanation:

Given

Base:

$Front = 100cm$

$Back = 50cm$

$Width = 40cm$

$Height = 70cm$

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

$Area = \frac{1}{2}(Front + Back) * Width$

$Area = \frac{1}{2}(100cm + 50cm) * 40cm$

$Area = \frac{1}{2}(150cm) * 40cm$

$Area = 75cm * 40cm$

$Area = 3000cm^2$

$Volume = Area * Height$

$Volume = 3000cm^2 * 70cm$

$Volume = 210000cm^3$

$1cm^3 = 0.001L$

So:

$Volume = 210000 * 0.001L$

$Volume = 210L$

Apollo 8 orbited the moon in a circular orbit. Its average altitude was 185 km above the moon's surface. Create an equation to m

Marta_Voda [28]

You probably haven't learnt this but the general equations for circle with centre at the origin is x^2+y^2=R^2 where R is the radius of the circle so R^2=(1737+185)^2.I am lazy to press my calculator so type it in yourself.
