Answer:
40cm
Step-by-step explanation:
A=s*s
A=10*10
A=100 cm^2
P=4*s
P=4*10
P=40 cm
"s" represents side
Answer:
13 ft by 15 ft
Step-by-step explanation:
2x+2y=56
x+y=28
x×y=195
13+15=28
13×15=195
<h3>
Answer: 1/9</h3>
Work Shown:
If the blue die shows a "2", then the red die must take on the values from the set {3, 4, 5, 6} in order for the sum of both dice to be larger than 4.
2+3 = 5
2+4 = 6
2+5 = 7
2+6 = 8
There are 6*6 = 36 total ways to roll two dice and exactly 4 ways to get the conditions stated above. The probability of getting a sum greater than 4 is 4/36 = 1/9.
CD/DB=AC/AB
DB=3.8; AC=4.6; AB=6.8
CD/3.8=4.6/6.8
Solving for CD:
CD=3.8*4.6/6.8
CD=2.570588235
Rounded to one decimal place:
CD=2.6
Answer: The length of CD is 2.6
