Answer:
Length of the hypotenuse = 8.5 units
Step-by-step explanation:
Given the length of the sides of an isosceles right triangle to be 6units
Hint: an hypotenuse is the longest line
To solve this, we use Pythagoras rule
Hypotenuse^2 = adjacent ^2 + opposite ^2
Adjacent = opposite = 6
Let our hypotenuse to be a
a^2 = 6^2 + 6^2
a^2 = 36 +36
a^2 = 72
To get a, let's find the square root of 72
a = 8.485 unit
Therefore, the length of the hypotenuse = 8.5 units
Area of a triange = 180 degrees
60 + 90 + 30= 180
180-30=150
Z=150 degrees
Answer:
B) 36/(y+4)
Step-by-step explanation:
Use the process of elimination.
A cannot work because we are changing the operation. Instead of dividing thirty-six by the sum of four and a number, we are dividing thirty-six by four, then adding the unknown number. This is not the same as the original expression, so we know it is not this.
Next, check C. C doesn't seem right either. Remember that, unlike multiplication and addition, you cannot flip the order in which the operation is being done and still get the same answer. C says four plus a number divided by thirty-six, which is entirely different from our original expression. So the answer is not C.
And finally, check D. D doesn't work either. With D, we are dividing thirty-six by a number, then adding it to thirty-six divided by four. This is not the same as our original expression, so D isn't it.
That leaves us with B. Does it work? Yes, because changing the y and the four still will give the same thing. And yes, because 36 is being divided by the sum of that number and four. So it is our answer.

Answer:
The percentage decrease = 0.9%
Step-by-step explanation:
Using the formula
Percentage Decrease = [ (Initial Value - Final Value) / |Initial Value| ] × 100
= [(9.80 - 9.71 ) / (9.80)] × 100
= [0.09 / 9.80] × 100
= 0.009 × 100
= 0.9%
Therefore, the percentage decrease = 0.9%
