Answer:

length of a rectangle is 5 more than twice the length. I believe

you mean the length of a rectangle is 5 more than twice the

width.

From the information given we can make two equations,

thus forming a system to solve. We know the perimeter

of a rectangle is 2(length + width) and area = length*width.

length of a rectangle is 5 more then twice the width:

L = 2w + 5

The perimeter is 130:

2(L+w) = 130

L+w = 65

Since we know L=2w+5 we can substitute that into 2nd equation

to solve for w

2w + 5 + w = 65

3w = 60

w = 20

L = 2w+5 = 45

The area is length*width = 20(45) = 900 square units

Answer:

The Solution to the equation 4ˣ = 9.2 is the option D ) x = 1.60

Step-by-step explanation:

Given:

$4^{x}=9.2$

To Find:

x = ?

Solution:

We know Logarithmic identity as

$\log (A)^{B}= B\log A\\$

$4^{x}=9.2$ .............Given

Taking Log on both the side we have

$\log 4^{x}=\log 9.2\\\textrm{using the above identity we get}\\\\x\log 4 = \log 9.2\\\\x=\frac{\log 9.2}{\log 4} \\\\\therefore x =\frac{0.9637}{0.6020} \\\\\therefore x =1.6008\\\\\therefore x = 1.60$

The Solution to the equation 4ˣ = 9.2 is the option D ) x = 1.60

Answer:

c, d. see attached

e. about 2.96 miles; about $1.63 million

Step-by-step explanation:

e. The x-coordinates of points A and B are 1/3 and 2/3 of the x-coordinate of "Downtown", respectively. The y-coordinates of A and B are 2/3 and 1/3 of the y-coordinate of "Town pool", respectively. Then the distances from A and B to the Mall can be found using the Pythagorean theorem:

A to Mall = √(4² +(10/3)²) = √(244/9) ≈ 5.20683 . . . miles

B to Mall = √(8² +(5/3)²) = √(601/9) ≈ 8.17177 . . . miles

The difference in distance is ...

(BM -AM) = 8.17177 -5.20683 = 2.96493 . . . miles

The mall is about 2.96 miles farther from point B than from point A.

The additional cost is the difference in miles multiplied by the cost per mile:

(2.96 mi)($0.550 M/mi) = $1.63 M

The additional cost of the longer road is about $1.63 million.
