Answer:

She have 40 coins in her purse

Step-by-step explanation:

1 dollar = 100 cents

14 dollar = 1400 cents

We are given that she has an equal number of each coin type

Let x be the no. of coins

Value of x coins of 5 cents = 5x

Value of x coins of 10 cents = 10x

Value of x coins of 20 cents = 20x

So, 5x+10x+20x=1400

35x=1400

x=\frac{1400}{35}

x=40

Hence  she have 40 coins in her purse

What are the coordinates of the center of the ellipse shown below?
photoshop1234 [79]

Answer:

Option D (7, -3)

Step-by-step explanation:

We know that the general equation of an ellipse has the form:

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} = 1

Where the point (h, k) are the coordinates of the center of the ellipse

In this case the equation of the ellipse is:

\frac{(x-7)^2}{4} + \frac{(y+3)^2}{16} = 1

Then

h=7\\\\k = -3

So The coordinates of the center of the ellipse are (7, -3)

alex41 [277]
The pints of paint that Mike needs to buy in order to paint 4 boxes is 9 pints.



How many pints is needed?


The first step is determine the total surface area of a box.


Total surface area of a cuboid = 2 (lw + wh + lh)


where:
l = length
w = width
h = height


2 x[ (5 x 9/2) + (9/2 x 7/2) + (5 x 7/2) ]
2 x ( 45/2 + 63/4 + 35/2) = 111.5ft


The second step is to determine the total surface area of 4 boxes:


111.5 x 4 = 446


Now, divide 446 by 50


446 / 50 = 9 pints
