Answer:
Percent change in the price of gas is
Step-by-step explanation:
Percentage change equals the change in value divided by the absolute value of the original value, multiplied by .
Here
The percent change in the price of gas
Percent change in the price of gas is
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × ( r is the radius )
given arc = 63.48π , then
2πr × = 63.48π ( cancel 2π on numerator/ denominator )
r × π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
name the points
a=(x1,y1) b=(x2,y2)
a=(6,8) b=(9,10)
use the slope formula
replace
answer= The slope is equal to 2/3
a=(9,10) b=(6,8)
using the formula
slope will also be 2/3
Part B - Question 1
Distance for the spacecraft to travel from Venus to Jupiter = Distance of Jupiter from Sun - Distance of Venus from Sun
⇒ Distance for the spacecraft to travel from Venus to Jupiter = 4.838 × 10⁸ - 6.724 × 10⁷
⇒ Distance for the spacecraft to travel from Venus to Jupiter = 483,800,000 - 67,240,000
⇒ Distance for the spacecraft to travel from Venus to Jupiter = 416,560,000
⇒ Distance for the spacecraft to travel from Venus to Jupiter = 4.1656 × 10⁸
Part B - Question 2
Combined distance of Mercury, Venus, and Earth from the Sun = Distance of Mercury from Sun + Distance of Venus from Sun + Distance of Earth from Sun
⇒ Combined distance of Mercury, Venus, and Earth from the Sun = 5.7909 × 10⁷ + 6.724 × 10⁷ + 9.296 × 10⁷
⇒ Combined distance of Mercury, Venus, and Earth from the Sun = 21.8109 × 10⁷
⇒ Combined distance of Mercury, Venus, and Earth from the Sun = 2.18109 × 10⁸
Distance of Neptune from the Sun = 2.793 × 10⁹
Hence, we can see that the combined distance of Mercury, Venus and Earth from the Sun is <u>less</u> than that of Neptune from the Sun.
Part B - Question 3
If Earth was 10 times farther away from the sun, then the new distance between the Sun and the Earth = 10 × 9.296 × 10⁷
⇒ New distance between the Sun and the Earth = 9.296 × 10⁸
Now, the Earth will be closest to Saturn, which is 8.907 × 10⁸ away from the Sun
New Distance between Earth and Saturn = Distance of Earth from Sun - Distance of Saturn from Sun
⇒ New Distance between Earth and Saturn = 9.296 × 10⁸ - 8.907 × 10⁸
⇒ New Distance between Earth and Saturn = 0.389 × 10⁸
⇒ New Distance between Earth and Saturn = 3.89 × 10⁷ (in scientific notation)
⇒ New Distance between Earth and Saturn = 38,900,000 (in standard notation)
Part B - Question 4
Speed of space shuttle = 28,000 km per hour
Time spent to travel from Saturn to Earth =
⇒Time spent to travel from Saturn to Earth =
⇒Time spent to travel from Saturn to Earth =
⇒Time spent to travel from Saturn to Earth =
⇒Time spent to travel from Saturn to Earth = 28,490.7 hours
⇒Time spent to travel from Saturn to Earth = 28,491 hours
Hence, it will take 28,491 hours or 2.8491 x 10⁵ hours for the space shuttle to travel from Saturn to Earth.
