Step-by-step explanation:
54^2 + a^2 = 90^2
2916 + a^2 = 8100
a^2 = 8100 - 2916
a^2 = 5184
take the square root of 5184
a = 72
you could have also guessed that its a 3 4 5 right triangle
all the sides are multiples of 3 4 or 5
A.You have to multiply the Original price(96) by todays discount(1/2)
96×(1/2)=48
Then to find the price 5 days from now you multiply the Original price(96) by the discount 5 days from now(2/3) but this time you subtract what you get from the original price 96×(2/3)=64
96-64=32 or the price of the coat 5 days from now
B. To find how much she would save subtract todays price(48) by the price 5 days from now(32)
48-32=16 She would save 16 dollars
Answer:
Choice C
Step-by-step explanation:
4x+80=180 degrees
summation of all angles in a triangle is 180°
6×10^4
We use 6 because the # has to be greater than or equal to 1 but less than or equal to 10.
10^4=10000
10000×6=60000
