Yes Jackie would have enough money to buy a CD player. So you would have to do 32.95 times that by 30% (.3) and would get 9.885 which you would round that to 9.89 dollars.
Answer: 1.455 km
Step-by-step explanation:
First lets convert 145,500 cm in m.
145500 × 10^-2 m ( NOTE that c = 10^-2 )
= 1455 m
Now convert 1455 m in km.
1455× 10^-3× 10^3 m
= 1455 × 10^-3 km (NOTE that k= 10^3)
= 1.455 km

Answer:
A. 12.28 km²
Step-by-step explanation:
The area of the figure is the sum of the areas of its parts. The area of the triangular part is ...
A = 1/2bh
A = 1/2(3 km)(4 km) = 6 km²
__
The area of the semicircular part is ...
A = 1/2πr²
A = 1/2(3.14)(2 km)² = 6.28 km²
__
Then the area of the figure is ...
6 km² + 6.28 km² = 12.28 km²
Answer:
9.42
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 9.42
Intersecting lines? Coordinate plane? Not sure if correct it’s my guess this question is too confusing
