The answer is 5. 25^1/2 is the same thing as the square root of 25. The square root of 25 is positive 5 or negative 5 because
5 x 5 = 25 and -5 x -5 = 25.
Dividing a whole number and an improper fraction seems tricky, but it just has one or two more steps than the normal process. First, convert the whole number "9" into a fraction by giving it a denominator of "1". It should look like 9/1. Now that both numbers are converted into like formats (improper fractions), you should have 9/1 divided by 5/3.
Second, flip 5/3 over into 3/5 - this is the "reciprocal". Now you have 9/1 divided by 3/5. It's just a matter of multiplying across the math sentence. Multiply the numerators (9x3) and the denominators (1 x 5). Your new fraction should be 27/5. This is your answer in the improper fraction format.
You can create other formats depending on the expected answer. For a mixed number, "divide your fraction UP" (27 divided by 5) which gives you 5 and 2/5. This can be further converted into 5.4 if you need your answer in decimal form.
Given :
a-b = c-d ...1)
b = d-1 ...2)
c = 6
To Prove :
a = 5
Solution :
Adding equation 1 and 2, we get :
(a-b) + (b) = (c-d) + (d-1)
a = c -1 ...3)
Putting given value of c = 6 in above equation, we get :
a = 6 - 1
a = 5
Hence, proved.
Answer:
300 ft
Step-by-step explanation:
Given that a city planner wants to build a ramp onto a highway. The vertical distance that the ramp goes up is 160ft. The length of the ramp is 340ft and represents the hypotenuse of a right triangle.
i.e. the triangle formed is a right one with hypotenuse 340 ft and one side 160ft. The other side is the horizontal distance the ramp will cover say x
Then by Pythagorean theorem we get
Thus horizontal distance the ramp will cover = 300 ft.
0.4 ^3 = 0.4 x 0.4 x 0.4
0.4 x 0.4 = 0.16
0.16 x 0.4 = 0.064
your answer is 0.064
hope this helps
