What is 3/5 divided by 9/5?

Need help asap The answer is 100 or 126

Serga [27]

Answer:

The surface area of the cone is 126π cm².

Step-by-step explanation:

The surface area of a cone can be found using this formula:

$\text{SA} = \pi r ^2+\pi r l$
where r = radius and l = slant height

In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.

Substitute these values into the formula for the surface area of a cone.

$\text{SA}= \pi (9)^2+ \pi(9)(5)\\$
$\text{SA}= \pi (81)+ \pi(45)$
$\text{SA}= 126 \pi$

The surface area of the right cone is 126 π cm².

Carrie place is a 10 foot ladder against the wall if the ladder makes an angle of 65° with the level ground how far up the wall

natita [175]

Answer:

9......

Step-by-step explanation:

A right-angled triangle in the image below will be formed.

Now, we will make use of the trigonometric rule......

But before that, how do know the perfect rule to apply so as to solve the problem?

#. The side facing the angle 65 deg. is called the Opposite side

#. The side facing the angle 90 deg. is called the Hypotenuse

#. While the last side is called the Adjacent

Now, Looking at our question, we were given the Hypotenuse and asked to look for the Opposite side....This is where we apply the trigonometric rule

Sine(θ)=Opposite/Hypotenuse

Therefore,

Sine 64 = Opposite/10

Opposite = 10 x sine64

Opposite = 10 x 0.9

Opposite = 9cm

You are driving in France and see the price of gasoline is 2.099 euros per liter. Use the facts below to calculate the price in

Dahasolnce [82]

Answer: $\$10.503$

Step-by-step explanation:

Knowing that the price of gasoline in France is 2.099 euros per liter, you can follow these steps in ordere to calculate the price of the gasoline in US dollars per gallon:

1. Convert 2.099 euros to US dollars:

$(2.099\ euros)(\frac{1\ US\ dollar}{0.7564\ euros})=2.774\ US\ dollars$

Then, the price in US dollars per liter is $2.774\ US\ dollars\ per\ liter$

3. Knowing that:

$1\ liter=1.0567\ quarts\\\\4\ quarts = 1\ gallon$

You can make the conversion from 1.0567 quarts to gallons:

$(1.0567\ quarts)(\frac{1\ gallon}{4\ quarts})=0.2641\ gallons$

4. Set up the following proportion:

$\frac{2.774}{0.2641}=\frac{x}{1}$

Where "x" is the the price in US dollars per gallon.

5. Solving for "x", you get:

$\frac{(2.774)(1)}{(0.2641)}=x\\\\x=10.503$
