X=amount of pencils

.42x+1.45=6.91

6.91-1.45=5.46

5.46/.42=13

aleksklad [387]

So you know the compound continuously formula is $A = Pe^{rt}$ . Thus, just plug in. $A = (1500)e^{(.05)(4)}$ Plug that into your calc to get $1832.

Varvara68 [4.7K]

We know that
Applying the Pythagoras Theorem
c=²=a²+b²
where c is the diagonal of the wall
a=12 ft
b=6 ft
c²=12²+6²-----> c²=144+36-----< c²=180-----> c=√180------> c=6√5 ft

the answer is
<span>the exact length of the brace is 6</span>√5 ft

PLEASEE HELPP....Simplify the expression using properties of exponents.

Aleks04 [339]

Answer:

D

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{n} }{a^{m} }$ = $\frac{1}{a^{(m-n)} }$

Given

$\frac{25a^{-5}b^{-8} }{5a^{4}b }$

= $\frac{25}{5}$ × $\frac{a^{-5} }{a^{4} }$ × $\frac{b^{-8} }{b^{1} }$

= 5 × $\frac{1}{a^{(4-(-5))} }$ × $\frac{1}{b^{(1-(-8))} }$

= 5 × $\frac{1}{a^{9} }$ × $\frac{1}{b^{9} }$

= $\frac{5}{a^{9}b^{9} }$ → D
