Area = width * length
6120/72 = 85 ft

The length is 85, Because if you divide 6120 by 72 you will get 85. <span />

Suppose y = 2x +10. Find y if x = -2.

liubo4ka [24]

If x = -2, y = 6.

To solve this quesiton, we need to find the value of y if x is equal to -2. We can do this by substiuting the value of x and then solving.

y = 2 (-2) + 10

y = -4 + 10

y = 6

The first term of a geometric sequence is 32, and the 5th term of the sequence is 818 .

sammy [17]

Answer:

$32,24,18,\frac{27}{2} ,\frac{81}{8}$

Step-by-step explanation:

Let x, y , and z be the numbers.

Then the geometric sequence is $32,x,y,z,\frac{81}{8}$

Recall that term of a geometric sequence are generally in the form:

$a,ar,ar^2,ar^3,ar^4$

This implies that:

a=32 and $ar^4=\frac{81}{8}$

Substitute a=32 and solve for r.

$32r^3=\frac{81}{8}$

$r^4=\frac{81}{256}$

Take the fourth root to get:

$r=\sqrt[4]{\frac{81}{256} }$

$r=\frac{3}{4}$

Therefore $x=32*\frac{3}{4} =24$

$y=24*\frac{3}{4} =18$

$z=18*\frac{3}{4} =\frac{27}{2}$

A Tourist Information Center is between a Bus Station and a Train Station. When mapped on a grid, the Tourist Information Center

deff fn [24]

Given :

The Tourist Information Center is located at (11,0) and the Bus Station is located at (-1,-10).

Also , Tourist Information Center is between a Bus Station and a Train Station.

To Find :

The point of location of train station .

Solution :

Let , point of location of train station is ( x,y ).

We know , mid-point of two points ( a, b) and ( c, d ) is given by :

$(\dfrac{a+c}{2},\dfrac{b+d}{2})$ .

Since , Tourist Information Center is between a Bus Station and a Train Station.

So , it is given by :

$( 11 , 0 ) = (\dfrac{-1+x}{2},\dfrac{-10+y}{2})$

Comparing both coordinate :

$\dfrac{x-1}{2}=11\\\\x=22+1\\\\x=23$

and

$\dfrac{y-10}{2}=0\\\\y=10$

Therefore , Train Station is located at point ( 23 , 10 ) .

Hence , this is the required solution .
