Answer:
85m
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
b=72m, l=?
perimeter =314m
314=2(l+72)
314/2= l+72
157=l+72
l=157-72
l=85m

Answer:
Distance is 13.6 units.
Which means it is 13
Step-by-step explanation:
Given a grid shows the positions of subway stop and house. The subway stop is located at (-7, 8) and house is located at (6, 4).
we have to find the distance between house and the subway stop.
Points are (-7, 8) and (6, 4).
Using distance formula,
D= /(x2-x1)^2+(y2-y1)^2} = (6-(-7))^2+(4-8)^2=(13)^2+16}={169+16}={185}=13.60147\sim13.6units.
Hence, distance between house and the subway stop is 13.6 units.
Answer:
2/5
Step-by-step explanation:
Ok there are 4+3+1+2 pairs of socks in all... Aka 10 sock pairs in all.
There are 4 white pairs. So the probability she selects a white pair is 4/10.
4/10 can be reduced to 2/5.
Answer:
4/5 of 3 = 12/5
2/9 of 20 = 40/9
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The first term = 1500
2nd term = 900
3rd term = 540
The series is a GP.
r = 900/1500 = 0.6
The sum of the first 10 term, S₁₀, is as calculated below.
Sn = a(1-rⁿ)/(1-r)
S₁₀ = 1500(1 - 0.6¹⁰)/(1 - 0.6)
= 1500 × 0.9939/0.4
= 3,727.125 m
