Answer:
the first one will be 7/32
the second one is 5/36
Answer:
10.6 ft
Step-by-step explanation:
to find the diagonal length of the stairway we can use the pythagorean theorem or a^2 + b^2 = c^2
6'4" is also 6 1/3' or 19/3'
8'6" is also 8 1/2' or 17/2'
now square them both
361/9 + 289/4
make them have the same denominator
1444/36 + 2601/36
add them
4045/36
take the square root
10.6000524 is your answer
10.6 ft
Answer:1/25
Step-by-step explanation: do 5 to the second power which will get all combinations then do 1 as the numerator over the denominator which is the number of combinations.
Answer:
D
Step-by-step explanation:
The interest is compounded annually, which means that interest from the previous year earns you even more money next year.
It should be obvious that after one year Alexis will have
$475 + $475 * 1.25% = $475 * 100% + $475 * 1.25% =
= 101.25% * $475 = 1.0125 * $475
Then, next year she would have
1.0125 * $475 + (1.0125 * $475) * 1.25% =
= (1.0125 * $475) * 1.0125 = 1.0125^2 * $475
See the pattern?
Alexis will have $475 * 1.0125^x after x years.
Answer:
The hight length : h
The base length : a
Apply the Pythagorean theorem in the right triangle :
h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²
