Answer:

B) 8^1/3

Step-by-step explanation:

It is B) 8 ^1/3

we can write 8 as 2^3

8^1/3 = (2^3)^1/3

= 2^3/3        [3/3 = 1]

= 2^1

= 2 which is a whole number.

Answer: B) 8^1/3

Hope this will helpful.

Thank you.

Suppose that 13 inches of wire costs 52 cents. At the same rate, how many inches of wire can be bought for 32 cents?
kirill115 [55]

Answer:

So we have a ratio which you have specified 13:52. So we just need to get the same ratio for 13. 32/52 is how we get 32 from multiplying by 52. So now we just need to multiply it for 13 also'

13*32/52 = 8. Therefore the answer to this is 8

A farmer sold 35 bags of rice at 25 % profit. If he sold each bag for ?7500:00. How much was his profit on 25 of the lot.
Doss [256]
Suppose that the farmer had bought the rice at x dollars per bag and had sold them at a 25% markup.  How much did the bags cost him before he added the markup?  1.25x =$75 results in $75/1.25, or $60 per bag.

If he sold 25 bags, his profit would be 1.25($60/bag)(25 bags) = $1875.

I very seriously doubt that the rice was $7500 per bag.  Perhaps you meant $75/bag...?

The legs of a right triangle are 10 centimeters and 24 centimeters long. What is the length of the hypotenuse?
Rina8888 [55]
A² + b² = c²

Where a and b are the legs and c is the hypotenuse

So, plug in 10 for one of the legs and 24 for the other leg

c will be left blank because that is what you are trying to find, the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

Take the square root of both sides of the equation to isolate c

√676 = √c²

Square of c and the square root cross out on the right

Take the square root of 676

c = 26

So, the length of the hypotenuse is 26 centimeters
