Answer:
20% decrease
Step-by-step explanation:
First, let's find the net decrease: Peter started at 80kg and his weight is now 64kg, which is a 16kg decrease. Next, we need to find what percentage of 80kg 16kg represents. First, let's find what part of 80 is 16:
16/80 = 1/5
To convert this to a percent, we need to find an equivalent fraction to 1/5 with a denominator of 100. To do this, we can multiply the numerator and denominator of 1/5 by 20, giving us 20/100, or 20%.
90-25 = 65
65/2 = 32.5
32.5+25 = 57.5
C is 32.5 degree.
D is 57.5 degree.
Answer:
11x^2+x-1
Step-by-step explanation:
To do so, just add the two polynomials together as such:
11x^2 +0x-5 plus
0x^2+1x-4 equals
11x^2+x-1
If she used rounding she would’ve gotten -25×10 equals -250
