Answer:
He will run 31.6 miles in two weeks.
Step-by-step explanation:
6 days a week = 2.3 miles
6 days · 2 weeks = 12 days total running 2.3 miles
1 day a week = 2 miles
1 day · 2 weeks = 2 days total running 2 miles
(12 · 2.3) + (2 · 2)
27.6 + 4
31.6 miles
Answer:
Q1, x=2 and all sides equal 8
Q2, x=3, MN and MP equal 10 and NP equals 8
Step-by-step explanation:
On an equilateral triangle all sides are equal
6x-4=3x+2
6x=3x+6
3x=6
x=2
6x-4
6(2)-4
12-4
8
On a isosceles triangle the two long sides are equal
4x-2=5x-5
4x=5x-3
-x=-3
x=3
4x-2
4(3)-2
12-2
10
3x-1
3(3)-1
9-1
8
Answer:
what do I do again
Step-by-step explanation:
First the 3.1 hr is one standard deviation away from the mean:
2.5 + 0.6 = 3.1 hr. then the one standard deviation away from the mean contains 68% of the total population. so the percent that is higher from 3.1 hr is
% higher 3.1 hr = ( 100 - 68) / 2
% higher 3.1 hr = 32 / 2
% higher 3.1 hr = 16 %
