6/8 = 0.75
0.75 x 100 = 75%
This is a right triangle equation
so a^2 + b^2 = c^2
c^2 is the hypotenuse and the 15 feet
a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144
the square root of 144 is 12
the tree is 12 feet tall
Well we know that 1 centimeter = 50 miles, so 2 centimeters = 100 miles. Now we have to find what 0.4 centimeters equals. To do this we must find 40% of 50.
We simply multiply 0.4 and 50 to get our answer.
0.4 × 50 = 20. So we add 20 to 100.
20 + 100 = 120
So 2.4 centimeters = 120 miles.
Hope I helped!
think its a=63 mainly based upon the two llooking similar and the bottom one is 63
Answer:
