The automaker of your new car recommended an oil change following the 5,000 miles and then every 3,000 miles thereafter.if you p

Rus_ich [418]

Answer:

3 oil changes

Step-by-step explanation:

1. Find an equation that represents this word problem: 3000x + 5000 = y

Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.

2. Solve for x: 3000x + 5000 = 13000 3000x=8000

3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year

OBC is a sector of a circle with centre o and radius 9cm work out the area of the shaded region as a percentage of the area of s

NARA [144]

Answer:

83.7 %

Step-by-step explanation:

To get the area of the shaded region, we will following these steps.

Step one: Get the area of the sector of the circle.

The area of the sector of the circle can be obtained using the formula:

$Area = \frac{\theta}{360}\times \pi r^{2}$

Theta will be 60 degrees because triangle OAD is an equilateral triangle

Hence, $Area = \frac{60}{360}\times \pi \times 9^{2}= 42.42cm^{2}$

Step Two: Get the area of the equilateral triangle

The area of the equilateral triangle can be got using the formula

$Area = \frac{1}{2} Base \times Height$

The height of the triangle can be got by drawing an imaginary line bisecting the triangle into two parts and applying the Pythagoras' theorem to any of the resulting right-angled triangles formed.

This will be $height =\sqrt{4^{2}-2^{2}} =3.46cm$

Thus $Area = \frac{1}{2}\times 4\times 3.46=6.93cm^{2}$

Step Three: Subtract the area of the triangle from the area of the sector

Area of the shaded portion = $42.42cm^{2}-6.93cm^{2}=35.49cm^{2}$

Step Four: Divide the area of the shaded portion by the area of the entire shape and multiply the result by 100:

Expressing the ratio of the two areas as a percentage, we have

$\frac{35.49}{42.42} \times 100\approx 83.7 %$ %
