Which of the following will be equal to 1⁄4?
docker41 [41]

Answer:

C - 100% of 0.25

Step-by-step explanation:

This answer is basically the same as 25% of 100, just worded differently to confuse you.

25 is 1/4th of 100, so this should be the answer. :)

If you're curious of what the other answers amount to:

One hundredth of 250 = 2.5

50% of 5 = 2.5

40% of 1 = 0.4

Perimeter of an isosceles triangle is 90 m. If the length of the two equal sides is three fourth of the unequal side , find the
Sveta_85 [38]

Answer:

The length of the equal side is 27 meters each and that of the unequal side is 36 meters

Step-by-step explanation:

An isosceles triangle is a triangle with two sides being equal (also two equal base angles).

Let us assume the length of the two equal sides to be x meters each, and the length of the unequal side to be y meter. Since the perimeter of the triangle is 90 m, it can be expressed as:

x + x + y = 90

2x + y = 90

But the length of the equal side is  three fourth of the unequal side, i.e x = 3/4y

Therefore:

2(3/4y) + y = 90

3/2y + y = 90

2.5y = 90

y = 90/2.5

y = 36 meters

Also x = 3/4 * 36 = 27 meters

The length of the equal side is 27 meters each and that of the unequal side is 36 meters
