Answer: Violet has 5 dimes and 15 quarters.

Step-by-step explanation:

let x denotes the number of dimes and y denotes the number of quarters.

Given : Violet has $4.25 worth of dimes and quarters .

Also, 1 dime = $0.1

1 quarter = $0.25

i.e. 0.1x+0.25y=4.25           (1)

She has 3 times as many quarters as dimes.

i.e y=3x                               (2)

Substitute the value of y in equation (1) , we get

0.1x+0.25(3x)=4.25      

\Rightarrow\ 0.1x+0.75x=4.25      

\Rightarrow\ 0.85x=4.25  

 

Divide both sides by 0.85 , we get

x=5

Substitute the value of x in (2) , we get

y=3(5)=15

Hence, Violet has 5 dimes and 15 quarters.

A rectangular box is 6 inches wide 10 inches long and 2 inches tall how much wrapping paper is needed to cover the box exactly
stepladder [879]

Answer:

184 in²

Step-by-step explanation:

Given :

Width, w = 6 inches

Length, l = 10 inches

Height, h = 2 inches

To obtain how much wrapping paper is needed ; we take the surface area of the box

Surface area = 2(lw + lh + wh)

Surface area = 2((6*10) + (6*2) + (10*2))

Surface area = 2(60 + 12 + 20)

Surface area = 2(92)

Surface area = 184 in²

The amount of wrapping paper needed = 184 in²

lana66690 [7]
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem:

 - <span>The angle of elevation from Madison to the top of the Statue of Liberty is 79 degrees.
 - Madison is standing 58.2 feet from its base.

 -Madison is 5 feet tall.

 2. Therefore, you have:

 Sin</span>α=opposite/hypotenuse
<span>
 Sin(79°)=x/58.2
 x=(58.2)(Sin(79°))
 x=57.13 ft

 3. Now, you can calculate the height of the Statue of Liberty, as below:

 height=x+5 ft
 height=57.13 ft+5 ft
 height=62.13 ft

 4. Therefore, as you can see, the answer is: 62.13 ft
