The answer would be 480 and because you multiply 30 times 12 you will get 360 and then you add that to the money he already has which is 120 so the total amount is 480
Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 3 ( add 3 to both sides )
y + 3 = x
change y back into terms of x, then
(x) = x + 3 → B
An integer is a rational number with a denominator of 1.or, more commonly just what you think of as a counting number, but may be negative.an irrational number cannot be expressed as a fraction. When written down as a decimal, they never terminate, so a decimal value is not exact. There are various kinds of irrational numbers.
For a 7*7=49 so sqrt(49)=7
6*6=36 so sqrt(36)=6
and since sqrt(x) is am increasing function then
6 < sqrt(42) <7
you do the same for b but with 4 values :
like 4*4*4= 64
and 3*3*3=27
Answer:
The unknown angle =
27°
Note :
SOH = Sin angle = Opposite/hypotenuse
CAH = Cos angle = Adjacent/Hypotenuse
TOA = Tan angle = Opposite/Adjacent
