$3 \frac{1}{2} r = 28 \\ \frac{7}{2} r = 28 \\ \frac{ \frac{7}{2} }{ \frac{7}{2} } r = \frac{28}{ \frac{7}{2} } \\ r = \frac{ \frac{56}{2} }{ \frac{7}{2} } \\ r= \frac{56}{7}$

$1 \frac{1}{2} c =6 \\ \frac{3}{2} c= \frac{12}{2} \\ \frac{ \frac{3}{2} }{ \frac{3}{2} } c= \frac{ \frac{12}{2} }{ \frac{3}{2} } \\ c= \frac{ \frac{12}{2} }{ \frac{3}{2} } = \frac{12}{3} =4 \\ c=4$

If a 30-foot tree casts an 18-foot shadow, find the length of the shadow cast by a 27-foot tree.

ipn [44]

Answer:

16.2 foot shadow

Step-by-step explanation:

Let the shadow cast by 27 foot tree be x.

Using ratio and proportions,

18 / 30 = x / 27

(18 x 27) / 30 = x

x = 486 / 30

x = 16.2

The Perimeter of the quadrilateral is 30 centimeters. Find the length of each side. The sides are: x+5, x+3, 2x-2, x^2-2x

Nitella [24]

Answer:

9 cm, 7 cm, 6 cm and 8 cm

Step-by-step explanation:

The perimeter is the sum of all the sides.

4 sides' expressions are given, so we add them and equate to 30.

$x+5+x+3+2x-2+x^2-2x=30\\x^2+2x+6=30\\x^2+2x+6-30=0\\x^2+2x-24=0\\(x+6)(x-4)=0\\x=-6,4$

Note: we disregard the value of x = -6, because it is going to give us side with negative length, that can't happen!

So, we take x = 4

Hence, length of each side is:

x + 5 = 4 + 5 = 9 cm

x + 3 = 4 + 3 = 7 cm

2x -2 = 2(4) - 2 = 8 - 2 = 6 cm

x^2 - 2x = (4)^2 - 2(4) = 16 - 8 = 8 cm

These are the lengths of 4 sides: 9 cm, 7 cm, 6 cm and 8 cm.

Help asap brb.asap asap will give max points

STatiana [176]

Answer:

$3^{3}$

Step-by-step explanation:

Note: When you divide exponents with the same constant, the exponent will be subtracted, and vice-versa, when you multiply exponents with the same constant, the exponents will be added.

$\frac{3^{-9} }{3^{-12} } \\= 3^{-9-(-12)} \\=3^{-9+12} \\=3^{3}$
