3.45 rounded to the nearest tenth is 3.5.
1.23 rounded to the nearest tenth is 1.2.
0.85 rounded to the nearest tenth is 0.9.
To find how much further Molly walked than her brother and sister combined, you'd have to combine the amount of miles Molly's brother and sister walked:
1.2 + 0.9 = 2.1
Next, you would have to subtract Molly's amount of miles walked with the combination of her brother and sister's miles walked:
3.5 - 2.1 = 1.4
So, Molly walked 1.4 more miles on her hike than her brother and sister had walked combined.
Answer:
Approximately 50% of the vehicle speeds were less than 42 mph
Step-by-step explanation:
The normal distribution is symmetric:
That is, 50% of the measures are below the mean and 50% of the measures are above the mean.
In this problem, we have that:
Mean = 42 mph
So
Approximately 50% of the vehicle speeds were less than 42 mph
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
Answer:
(-14+3/2b) - (1+8/2b) goes with -15-5/2b
(5+26)+2b+3/2) goes with 4b+13/2
(-10+b)+(7b-5) goes with 8b-15
(7/2b-3)-(8+6b) goes with -5/2b-11
