Answer:

David find <u>8</u> quarters.

Step-by-step explanation:

Given:

David was in need for some money so he decided to clean out the water fountain at the mall he found 20 nickels and quarters.

The collection of nickels and quarters totaled to 2.6.

Now, to find the quarters David find.

Let the number of nickels be x

And the number of quarters be y

Thus, the number of nickels and quarters he found:

x+y=20.

⇒ x=20-y.........( 1 )

The totaled of nickels and quarters:

0.05x+0.25y=2.6

(As 1 nickel=$0.05 and 1 quarter=$0.25)

Now, putting the equation ( 1 ) in the place of x we get:

0.05(20-y)+0.25y=2.6

⇒ 1-0.05y+0.25y=2.6

⇒ 1+0.20y=2.6

<em>Subtracting both sides by 1 we get:</em>

⇒ 0.20y=1.6

<em>Dividing both sides by 0.20 we get:</em>

⇒ y = 8.

So, the quarters = 8.

Therefore, David find 8 quarters.

A ship is anchored off a long straight shoreline that runs north and south. From two observation points 16 miles apart on shore,
ELEN [110]
D - the shortest distance from the ship to the shore.
d / ( 17 - x ) = tan 32° = 0.62487
d / x = tan 53° = 1.32704
d = 0.62487 ( 17 - x )
d = 1.32704 x
0.62487 ( 17 - x ) = 1.32704 x
10.62279 - 0.62487 x = 1.32704 x
x = 10.62279 : 1.95191
x = 5.44226 miles
d = 5.44226 · 1.32704
Answer:
d = 7.222  miles

The line through (-2, 3) with slope 2/3 in point slope form​
Debora [2.8K]

Answer:

y - 3 = 2/3(x + 2)

Step-by-step explanation:

slope = 2/3

point-slope form --> y - y1 = m(x - x1)

y - 3 = 2/3(x - -2)

y - 3 = 2/3(x + 2)

point slope form of the line is y - 3 = 2/3(x + 2)
