Answer:
B
Step-by-step explanation:
To find the area of a parallelogram you do A=(b)(h) so 20x8=160. It's 160ft^2 because area is measured in square units.
Answer:
11
Step-by-step explanation:
You have to first make the 7 into a fraction (7/1) then keep, change, flip.
You keep the 7/1 as it is, you change the division sign into a multiplication sign, and you flip the 7/11 to 11/7. You then just multiply straight across to get 77/7 which is the same thing as 11/1 which is the same thing as 11!
Final answer:11
Answer:
n=946 and n=947
Step-by-step explanation:
n + (n+1) = 1893.
2n + 1 = 1893.
2n + 1 - 1 = 1893 - 1.
2n = 1892
2n/2= 1892/2
n=946
Complete question :
On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.
Answer:
1.497 * 10^8km
149700000 km
Step-by-step explanation:
Given that:
Time taken = 8 minutes 19 seconds
Speed of light = 3 * 10^8 m/s
Distance from earth to sun :
Speed * time
(3 * 10^8) * ((8 * 60) + 19)
(3 * 10^8) * 499
= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km
= 149700000000 m
= 149700000 km
= 1497
