You gave your little sister a good push on a swing and it made an arc of 12 ft. On the third swing it made an arc of 8.67 ft. Ho

10.2 ft Ans.

We solve this using geometric series.

A1 = 12 ft
A2 = ?
A3 = 8.67ft
Now, for geomteric progression,

$\frac{A1}{A2} = \frac{A2}{A3} 

$

$\frac{12}{A2} = \frac{A2}{8.67}$

$A2 * A2 = (A2)^{2} = \sqrt{12 * 8.67 }$

A2 = 10.2 ft

The length of a rectangular map is 15 inches and the perimeter is 50 inches. Find the width.

jonny [76]

P = 2(L + W)
P = 50
L = 15

50 = 2(15 + W)
50 = 30 + 2W
50 - 30 = 2W
20 = 2W
20/2 = W
10 = W.....so the width is 10 inches

Write an algebraic expression that represents the following statement: “7 less than the quotient of 5 and n" *

IrinaK [193]

$\huge\boxed{\boxed{\bold{\frac{5}{n}-7}}}$

$\hrulefill$

We'll start with the expression for the quotient of $5$ and $n$ , which means we'll use division:

$\frac{5}{n}$

Now we find $7$ less than that, meaning we'll use subtraction:

$\frac{5}{n}\bold{-7}$
