Answer:

c. 620

Step-by-step explanation:

1st: Find the area of the whole rectangle

The formula for a square is <em>l x w</em>

40x17=680

2nd: Find the areas of the rectangles

The are of a rectangle is the same formula for a square (<em>l x w)</em>

6 X 2.5=15

3rd: Multiply 15 by 4

This represents the number of smaller rectangles that are in the big rectangle

15 x 4= 60

4th: 680-60

This represents the amount of room that the students can wak on

common difference, d = -3

f1 = -13

An arithmetic sequence f(n) = f1 + d(n - 1)

so f(n) = -13 - 3(n - 1)

f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148

Answer:

f(46) = - 148

Please help me with this problem <br> Evaluate (-½·3)³

-Dominant- [34]

Answer: -27/8

Step-by-step explanation:

$\left(-\frac{1}{2}\cdot \:3\right)^3$

$\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=-a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:odd}$

$\left(-\frac{1}{2}\cdot \:3\right)^3=-\left(\frac{1}{2}\cdot \:3\right)^3$

$=-\left(\frac{1}{2}\cdot \:3\right)^3$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n$

$\left(\frac{1}{2}\cdot \:3\right)^3=\left(\frac{1}{2}\right)^3\cdot \:3^3$

$=-\left(\frac{1}{2}\right)^3\cdot \:3^3$

$=-\frac{1}{8}\cdot \:3^3$

$=-\frac{1}{8}\cdot \:27$

$=-\frac{27}{8}$
