The answer would be 2/3
Because there are 6 numbers on a die, and all of the odd numbers would be 1,3, and 5. The number less than 3 that is not already listed is 2. 1,2,3, and 5 are 4 numbers, making the answer 4/6. 4/6 is simplified to 2/3.

Hope this helps... mark as Brainliest plz

I'm pretty sure it'd be 4/6 and then it'd simplify to 2/3. You add together the possibilities of rolling an odd number (3/6) to the possibilities of getting a number less than 3 (2/6) and then subtract the number that they both had in common (which would've been the number 1). So it'd be 3/6+2/6=5/6 - 1/6. and you'd get 2/3

JK is tangent to a circle with centre H as shown below. What is HK ?<br> 8 mi<br> 15 mi
sashaice [31]

Given:

JK is tangent to a circle with center H

To find:

The length of HK.

Solution:

The image is attached below.

JK = 8 mi, HJ = 15 mi

JK is tangent to a circle.

The tangent is always perpendicular to the radius.

Therefore, m∠J = 90°

Using Pythagoras theorem:

HK² = JK² + HJ²

HK² = 8² + 15²

HK² = 64 + 225

HK² = 289

HK² = 17²

Taking square root on both sides.

HK = 17

The length of HK is 17 mi.

What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the so
wel

Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

/DE/^{2} = /EF/^{2} + /DF/^{2}

/16.2/^{2} = /EF/^{2} + /13.6/^{2}

262.44 = /EF/^{2} + 184.96

/EF/^{2} = 262.44 - 184.96

          = 77.48

EF = \sqrt{77.48}

     = 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.

The perimeter of a rectangular field is 354 yards. If the width of the field is 82 yards, what is its length?
nadya68 [22]
2w + 2l = 354  where w = width and l = length 
so we have
2*82 + 2l = 354
2l = 254 - 2*82 =  190
l = 95

length is 95 yards
