Answer:
4343
Step-by-step explanation:
To find multiple of 7 from 1 to 100,
Take the quotient of 100/7=14
n=100 (number of terms)
n=100-14 (Without Multiple of 7=number of terms - multiple of 7)
=>n=86
Sum of 1 to 100 => Sn = n/2(a + an)
=> Sn = 86/2(1+100)
=> Sn = 43(101)
=> Sn = 4343
Answer:
2x
Step-by-step explanation:
f(x)- g(x)
=5x-3-(3x-3)
=5x-3-3x+3
=2x
Answer:
Y = MX
Step-by-step explanation:
If two quantities X and Y maintain a proportional relationship with each other, then we can write this as Y ∝ X.
Now, converting this relation into the equation we write Y = MX ........ (1), where M is a constant.
Now, from the above equation, we can say that the rate of change of Y with respect to the unit change of X is always constant.
Graphically. this equation represents the graph of a straight line with a constant slope and passing through the origin. (Answer)
Answer:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x =
Then
∠ BOC = 2x = 2 × = ≈ 54.67° ( to 2 dec. places )
