The price of the television set after the instant rebate is applied is x-300. The tax applied portion of the expression is .07x. In this case, the instant rebate is $300 and the tax applied would be 7%. X is the initial cost of the TV before any discounts or taxes are applied.

Sam is renting one of two cars to go on a 300-mile trip. The first car can travel 75 miles on 5 gallons of gas. The second car c

Doss [256]

Solution:

The first car can travel 75 miles on 5 gallons of gas.

So per mile gas consumed by car $=\frac{5}{75}=\frac{1}{15}$ gallon

The second car can travel 240 miles on 20 gallons of gas.

So per mile gas consumed by car $=\frac{20}{240}=\frac{1}{12}$ gallon

It mean Sam should rent the First car.

Sam is renting one of two cars to go on a 300-mile trip.

So total number of gallons of gas required $=\frac{1}{15}*300=20$

Total cost of 20 gallons of gas $=\frac{49.42}{14}*20= 70.6$ dollar

The diagram shows a sector of a circle radius 10cm

Yuki888 [10]

Answer:

$\text{Perimeter of sector = 43.6 (Rounded to the nearest tenth.)}$

Step-by-step explanation:

$\text{Perimeter of the sector = Radius + arc length + radius}$

$\text{Radius = 10 cm}$

$\text{Perimeter of the sector = 10 + arc length + 10 }$

$\text{Perimeter of the sector = 20 + arc length }$

$\text{arc length = (sector angle/ 360 ) * perimeter of the circle}$

$\text{Perimeter of a circle }=2\pi r$

$\text{sector angle} = 135$

$\text{arc length} = (135/ 360 ) * 2\pi (10)$

$= (3/8) 20\pi$

$= 15\pi /2$

$\text{Using }\pi =3.14$

$= 15 * 3.14 /2$

$= 23.55$

$\text{Perimeter of the sector = 20 + 23.55}$

$= 43.55$

$= 43.6 cm$

$\text{perimeter of the sector = 43.6 cm }$

What is the midpoint

liq [111]

Answer:

midpoint formula:

x1+x2/2 y1+y2/2

-4 + (-2)/2 which then simplifies to -6/2 and then to -3

2 + 2 /2 which then simplifies to 2

x= -3

y= 2

so (-3,2) is the coordinate point of the midpoint of this segment
