Which is greater, 13/35 or 2/5?
zhenek [66]
Hi there!

If you run into problems like this, remember to "Stay calm and find the common denom." That just means find the common denominator.

13/35 and 2/5 = 13/35 and 14/35

As you can tell, 2/5 is larger.

Hope this helps.

A circle has been dissected into 16 congruent sectors. The base of one sector is 1.17 units, and its height is 2.94 units. Using
worty [1.4K]

Answer:

The approximate area of the circle is 27.5184∧2

Step-by-step explanation:

In order to calculate the approximate area of the circle we would have to calculate the following formula:

approximate area of the circle=approximate area of one triangle*number of congruent sectors

number of congruent sectors=16

approximate area of one triangle=1/2*base*height

base=1.17 units

height=2.94 units

Therefore, approximate area of one triangle=1/2*1.17*2.94

approximate area of one triangle=1.7199 units∧2

Therefore, approximate area of the circle=1.7199 units∧2*16

approximate area of the circle=27.5184∧2

If the height of the base is 15 and the width of the base is 8 what is the length of the hypotenuse
tino4ka555 [31]

Answer:

The length of the hypotenuse is 17.

Step-by-step explanation:

15^2 + 8^2 = 17^2.

I found this out by doing:

15 x 15 = 225

8 x 8 = 64

225 + 64 = 289

\sqrt{289} = 17

Hope this helps you! :)

Find the surface area of a square pyramid with side length 4 mi and slant height 5 mi.
andriy [413]

Answer:

SA = 56 sq mi

Step-by-step explanation:

SA = area of base + 1/2(perimeter of base)(slant height)

SA = 16 + 1/2(16)(5)

SA = 16 + 8(5)

SA = 16 + 40
