Answer:
what is the question. I can help just need the question
Answer:
In short, 0 is the only number such that for any number x, x + 0 = x. ... So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1
<span>1 less than 4 times a number is 49...
</span>4x-11=49
now we add 11 on both sides and get...
4x=60
now we divide 4 on both sides...
x=15
(leave a thanks and a rating if i helped) c:
21: if the temperature is 16 and it drops to -15, we write
16 - (-15) = 16 + 15 = 31 degrees
22: if you start at 450 and go down 300, we write
450 - 300 = 150 feet below sea level
Formula for the circumference of a circle: C = pi x diameter
We are given the radius here, but we need the diameter. The diameter of a circle is equal to two times the radius.
diameter = 40 x 2 = 80 in
C = pi x 80
C = 80pi = 251.3 in
Hope this helps!! :)
