A slide 4.1 meters long makes an angle of 35° with the ground. To the nearest tenth of a meter, how far above the ground is the

Artemon [7]

Hey there! I'm happy to help!

We want to figure out what x is. Let's use a trigonometric ratio of our 35 degree angle to find it.

We see that x is opposite of the 35 degree angle. We also see that our hypotenuse 4.1 m. The hypotenuse is always across from the right angle.

The trigonometric ratio that deals with opposite and hypotenuse is the sine, which is the opposite divided by the hypotenuse. This gives us the following equation.

$sin35=\frac{x}{4.1}$

We want to solve for x, so we simply multiply both sides 4.1

$x=4.1(sin35)$

If we evaluate this on our calculators, we get 2.351663389......

We round this to the nearest tenth, giving us 2.4 m.

Have a wonderful day! :D

The radius of cylindrical water tank is 4.5 ft, and its height 6 ft, What is the volume of the tank?

NeTakaya

Answer:

$Volume=381.7 \,ft^3$

Step-by-step explanation:

Use the formula for the volume of a cylinder:

Volume= B times height

Being "B" the area of the cylinder's base (a circle of radius 4.5 ft.

Therefore the area of the base is:

$Area=\pi R^2 = \pi (4.5\,ft)^2=63.617\,ft^2$

So the volume of the cylinder is:

$Volume=B\,*\,h = 63.617\,* 6\,ft^3=381.7 \,ft^3$

A store pays $10.56 fora map of Africa and marks the price up by

nignag [31]

Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>

Side note: Another way that you can do this is by simply doing 1.5(10.56).
