Let the number be x.
Sum of 8 and the number = (8 + x) = 100
8 + x = 100
x = 100 - 8
x = 92.
The number is 92.
Answer:
17
Step-by-step explanation:
y=4(3)+5
y=12+5
y=17
Use the cosine rule.
c=AB=7
b=AC=8
a=BC=3
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
=(7^2+8^2-3^2)/(2*7*8)
=13/14
=0.9286
Answer:
2 examples would be
7 3/20
or
7 9/60.
Step-by-step explanation:
0.15 = 15/100
= 3/20.
So 7.15
= 7 3/20
