since 2 is the first significant digit, a nonzero, then we move the dot that way, it just so happen it's 8 spots to the right.
Answer:
60
Step-by-step explanation:
90÷2=45
45+75+m=180(sum of triangle)
120+m =180
m=180-120
m=60
Answer: 32
Step-by-step explanation:
we have in this case right triangle with a leg equal to 24 and a hypotenuse equal to 40
c^2=a^2+b^2
40^2=24^2+b^2
b^2=1600-576=1024
b=sqrt1024=32
Firstly, to calculate a price you need to change the percentage into a decimal. You do this by dividing it by 100.
45 / 100 = 0.45,
The discount price will be 55% of the original price,
55 / 100 = 0.55,
19 * 0.55 = 10.45,
So the discound price will be $10.45
Hope this helps!
