Answer:
true
Step-by-step explanation:
To round off a number to its nearest whole number, look at the first number after the decimal point. If the number is equal or greater than 5, add 1 to the number before the decimal point. If it is less than 5, add zero.
Because the first number after the decimal point is 3, which is less than 5, add zero to 16 . 16 + 0 = 16
If the number were 16.571, rounding off to the nearest whole number would give 17
Answer:
f(1) = 5, f(2) = 8, f(3) = 11
Step-by-step explanation:
Common difference refers to how you get from one value in the sequence to the next.
If f(0) = 2, f(1) = 2 + 3 = 5 etc
Answer:
∠2 = 55°
Step-by-step explanation:
Given that the triangle has 2 congruent sides then the triangle is isosceles.
Thus the 2 base angle are congruent, both equal to ∠2
The sum of the 3 angles in a triangle = 180
7x + 6 + 7x + 6 + 70 = 180, that is
14x + 82 = 180 ( subtract 82 from both sides )
14x = 98 ( divide both sides by 14 )
x = 7
Hence
∠2 = 7x + 6 = (7 × 7) + 6 = 49 + 6 = 55°
