The width of a rectangle is 5x -9.5 feet and the length is 9.5x + 10 feet. Find the perimeter of the
koban [17]

Answer:

Perimeter of the rectangle is 29x + 1 feet

Step-by-step explanation:

Length of the rectangle = 9.5x + 10 feet

Width of the rectangle = 5x - 9.5 feet

perimeter of rectangle = 2 ( length + width )

perimeter = 2 { (9.5x + 10) + (5x-9.5) }

perimeter = 2 ( 9.5x + 5x + 10 - 9.5 )

perimeter = 2 (14.5x + 0.5)

perimeter =29x + 1 feet

The components of vector a⃗ are ax = + 3.90 and ay = -4.00. What is the angle measured counterclockwise from the +x-axis to vect
Genrish500 [490]

The angle is the arctangent of the ratio of ay to ax. Since ay is negative and ax is positive, it is a 4th-quadrant angle.

... arctan(ay/ax) = arctan(-4.00/3.90) ≈ 314.27°

... about 5.48513 radians

Mr. Smith's $85,000 condominium is assessed at 35% of value. The tax rate is $2.70 per $100 of value. If the tax increases $.35
wel

Answer:

$907.38

Step-by-step explanation:

We have been given that Mr. Smith's $85,000 condominium is assessed at 35% of value.

First of all, we will find 35% of $85,000 as shown below:

\frac{35}{100}\times \$85,000

35\times \$850

\$29,750

We are also told that the tax rate is $2.70 per $100 of value. Now we will divide $29,750 by 100 as:

\frac{\$29,750}{\$100}=297.50

Since the tax rate is increased by $0.35 per $100 of value, so the new tax rate will be $2.70 plus $0.35.

\text{New tax rate}=\$3.05

\text{Amount of new tax}=\$3.05\times 297.50

\text{Amount of new tax}=\$907.375

\text{Amount of new tax}\approx \$907.38

Therefore, Mr. Smith's new tax will be $907.38.
