Answer:
1875 square miles
Step-by-step explanation:
There are a total of 10 women and 3 men. Let's define two variables:
- w: land inherited by a woman
- m: land inherited by a man
Given that they inherited a 30000 (square miles) of land and that each brother has inherited double what each sister has inherited, we can establish the next equations:
2*w = m
10*w + 3*m = 30000
Replacing the first equation into the second one, and solving for w:
10*w + 3*2*w = 30000
16*w = 30000
w = 30000/16
w = 1875 square miles
Your mom, and all of her sisters, inherited 1875 square miles each
Speed = 93km /h and 72km/h
Answer: The taxi went a distance of 554.7km
Step-by-step explanation:
Speed = Distance / Time
Distance covered in the first trip = Speed x Time
Time = 1 hour 54 min =1+0.9 hours =1.9hours
=93km / h x 1.9 hours =176.7km
Distance covered in the second trip = Speed x Time
Time = 5 hours 15min = 5+0.25hours =5.25hours
=72km / h x 5.25hours =378 km
Total distance =176.7km+378 km
=554.7km
Answer:
99 votes for ice cream
Step-by-step explanation:
4 + 11 + 8 + 7 = 30
270/30 = 9
to find the predictions multiply the votes by 9
ice cream has 11 votes
11 * 9 = 99
1) 32*10^4 is not written in scientific notation because the first factor is not a number betweem 1 and 10.
3.4 * 10^5 is the same number written in scientific notation.
2) 2.01x10^-5 is written in scientific notation.
