Answer:

The value of n = 8

Step-by-step explanation:

When two chords are intersecting each other then the product of their segments are equal.

<u>To find the value of n</u>

From the figure we can see that, two chords intersect each other

first part lengths are n and 3

second parts are 4 and 6

n * 3 = 4*6

3n = 24

n = 24/3 =8

Therefore the value of n = 8

How would you describe a meter in English units?

dalvyx [7]

The answer is letter A. A meter has nearly the same value to a yard, one yard approximately amounting to 1.09361 meter. The rest of the other measures are far from meter's value in distance.

a rectangle is 6 units "wide" and x -8 use long it has the same area of a triangle with a height of 7 units and a base of x minu

Mashcka [7]

Answer:

42 square units

Step-by-step explanation:

The area of the rectangle is the product of its length and width:

area = 6(x -8)

The area of the triangle is half the product of its base and height:

area = (1/2)(x-3)·7

These two areas are equal, so we have ...

6(x -8) = (1/2)(x -3)(7)

6x -48 = 3.5x -10.5 . . . . eliminate parentheses

2.5x = 37.5 . . . . . . . . . . . add 48 -3.5x

x = 15 . . . . . . . . . . . . . . . divide by 2.5

The area of the rectangle is ...

area = 6(15 -8) = 42 . . . . square units.

The average of 4 numbers is 98. If 3 of the numbers are 86, 87, and 91, what is the 4th number?

astraxan [27]

Average of 4 numbers, if the numbers are x,y,z,t then the average is (x+y+z+t)/4=average so

average=98
if 3 of the numbers are 86, 87 and 91 then what is the fourth number
assign
x=86
y=87
z=unknown
91=t

(86+87+z+91)/4=98
do parenthasees first
(264+z)/4=98
multiply both sides by 4 to get rid of fraciton
264+z=392
subtract 264 from both sides
z=128

the fourth number=128

olga2289 [7]

Answer:

(40 + 2x)feet

Step-by-step explanation:

see attachment for the figure.

Let 'L' represents the length of the rectangular swimming pool i.e 40ft wide.

and pool is bordered by square tiles that are x feet in length surrounding the pool

therefore,

In order to find the longest side of the pool and the tile border, take the sum of length of the swimming pool i.e 40 adding two times the wide of the square tiles

(40+2x)feet.
