If you divide the amount of Dollars by the amount of Euros you get the price of 1 Euro in Dollars.

$600/450€ = $1,33 per each Euro

Answer:

0.75 euros per dollar.

Step-by-step explanation:

It is given that on a trip, you had to change your money from dollars to euros.

You got 450 euros for 600 dollars. It means

450 euros = 600 dollars

We need to find the unit rate that describes the exchange.

\text{Unit Rate}=\dfrac{Euros}{Dollars}

\text{Unit Rate}=\dfrac{450}{600}

\text{Unit Rate}=\dfrac{3}{4}

\text{Unit Rate}=0.75

Therefore, the unit rate is 0.75 euros per dollar.

Jan had $126. she spent 1/6 of her money on her makeup and 2/3 of her money on shoes. How Much does Jan have left?
Jobisdone [24]

She has 1/6 of her money left, which is $21. 

2/3=4/6, so 4/6 + 1/6=5/6, which means she has 1/6 left.  Divide $126 by 6 and you get $21.

The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If
frutty [35]
For this case we have the following equation:
 w = 0.9* \sqrt{E}
 Where,
 w: The weight of a spring in pounds
 E: the energy stored by the spring in joules.
 Substituting values we have:
 w = 0.9* \sqrt{12}
 Making the corresponding calculation:
 w=3.12
 Answer:
 
the approximate weight of the spring in pounds is:
 
w=3.12

Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. What would you expect to see in the sampl
Anon25 [30]

Answer:

  1. Listing of 15 students
  2. Assignment of a sequential number to each student.
  3. The figured out sample size, i.e., 2.
  4. Selected sample using sampling frame 15 from Step 2 and your sample size from Step 3, i.e., 2  

Step-by-step explanation:

Random sampling is a piece of the sampling method where each example has an equivalent likelihood of being picked. An example picked randomly is intended to be an impartial portrayal of the all out populace. On the off chance that for certain reasons, the example doesn't speak to the populace, the variety is known as a sampling mistake. A random example is an example that is picked randomly. It could be all the more precisely called a randomly picked test. Random examples are utilized to stay away from inclination and other undesirable impacts. Random sampling is probably the least complex type of gathering information from the all out populace. Under random sampling, every individual from the subset conveys an equivalent chance of being picked as a piece of the sampling procedure.

Find the volume of a right circular cone that has a height of 12.7 m and a base with a circumference of 18.9 m. Round your answe
DochEvi [55]

Step-by-step explanation:

We have,

Height of cone, h = 12.7 m

Circumference of base, C = 18.9 m

The base of a circular cone is circular. The circumference of circle is given by :

C=2\pi r

r is radius

r=\dfrac{C}{2\pi}\\\\r=\dfrac{18.9 }{2\pi}\\\\r=3\ m

The volume of a right circular cone is given by the formula as :

V=\dfrac{1}{3}\pi r^2h

V=\dfrac{1}{3}\times 3.14 \times 3^2\times 12.7\\\\V=119.634\ m^3
