4. We can estimate the price per pound by rounding 14.5 up to 15, and rounding $25.52 to to $26. We can estimate that the price per pound is around $1.73

5. The price per pound of the beans is $1.76. To find the unit rate, you divide the price by the amount of the item. 25.52/14.5 = 1.76

6. Jeff walked 4.2 hours in total. 8.84/3.4 = 2.6

2.6 + 1.6 = 4.2

A right triangle has side lengths 5, 12, and 13 as shown below.
Leviafan [203]

Answer:

c

Step-by-step explanation:

a. 3in, 4in, 5 in

5^2 ?  3^2 + 4^

25   ?  9 + 16

25   =  25

Because the two sides are equal, this is a right triangle.

b. 5in, 6in, 7in

7^2  ?  5^2 + 6^2

49   ?  25 + 36

49   <  61

Because 49 < 61, this is an acute triangle.

c. 8in, 9in, 12in

12^2  ?  8^2 + 9^2

144    ? 64 + 81

144    < 145

Because 144< 145, this is an acute triangle.

If someone offers you a lottery ticket that has a 25 percent chance of winning $100, a 50 percent chance of winning $200, and a
g100num [7]

Answer: $375

Step-by-step explanation:

Given : The probability of winning $100 : P(100)= 0.25

The probability of winning $200 : P(200)= 0.50

The probability of winning $1000 : P(1000)= 0.25

Now, the the expected value of that lottery ticket is given by :-

P(100)\times 100+P(200)\times200+P(1000)\times1000\\\\=0.25\times100+0.50\times200+0.25\times1000\\\\=375

Hence, the the expected value of that lottery ticket =$375
