Answer:  # 4.) 9.4

#5.) 10.2 cm  

#6.) 5 inches .

Step-by-step explanation: Assuming that a right triangle is expected, use the <u><em>Pythagorean Theorem</em></u> to calculate the third side: a² + b² = c²

5^{2}+8^{2}=89  Then take the square root of 89. A calculator is handy for most of these!

√89 = 9.433981 .  Round to 9.4

2^{2}+10^{2}=104

√104 = 10.1980  Round to 10.2 <u>Remember to include the units, cm in the answer.</u>

<u>Memorize this one:</u>

<u>Given side lengths of 3 & 4, the hypotenuse is 5!</u>

3² + 4² = 5²   Called a "Pythagorean Triple"

9 + 16 = 25

The square on the hypotenuse is a perfect square of 5

No calculator necessary, and you are likely to see this ratio in other questions.

A right square pyramid has a slant height of 13 inches and a lateral area of 260 square inches. What is the volume of the pyrami
Fynjy0 [20]
260/4 = 65 square inches is area of a side 
area of a side = base*height/2 = base *13/2

65 = b*13/2

130=b*13

b = 10 so the side length equal 10 inches 

area of base = 10*10 = 100 

volume of a pyramid = area of base time height /3 

(the height of pyramid)^2 = 13^2 - 5^2

h^2 = 169 -25 = 144 

h = 12 

V = area of base time height /3 = 100*12/3 = 400 cubic inches 

hope this will help you

I have a hat that contains six nickels and five pennies. I draw coins from the hat at random, without replacement. Find the prob
Feliz [49]

Answer:

37/66

Step-by-step explanation:

To have removed at most 2 pennies out of 4 coins, you could have either selected 4 nickels, 3 nickels, and 1 penny or 2 nickels and 2 pennies.

There is only one way to select 4 nickels:  6/11 x 5/10 x 4/9 x 3/8  =  1/22

There are four ways to select 3 nickels and 1 penny; each way is:  6/11 x 5/10 x 4/9 x 5/8  =  1/66

    4 x 1/66  =  2/33

There are six ways to select 2 nickels and 2 pennies; each way is:  6/11 x 5/10 x 5/9 x 4/8  =   5/66

    6 x 5/66  =  5/11

Adding these probabilities:  1/22 + 2/33 + 5/11  =  37/66
