Answer:
A and D
Step-by-step explanation:
34 * 4 = 136 136 > 10
3 * 4 = 12 12 > 10
Answer:
(B)
Step-by-step explanation:
v^2 = v0^2 + 2ax
a = (v^2 - v0^2) / 2x
= (20^2 - 10^2) / 200
= 1.5 m/s
Answer:
True
Step-by-step explanation:
Given data
Diameter =6 yards
Radius R= Diameter/2= 6/2 = 3 yards
R²=3*3=9square yards
Hence R^2 = 9square yards= True
N-10=5-4n
n+4n=5+10
5n=15
n=3
Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m
