Answer:
7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 4² = (
)²
x² + 16 = 65 ( subtract 16 from both sides )
x² = 49 ( take the square root of both sides )
x = 
= 7
That is the other leg is 7 units
Answer:
67 degrease
Step-by-step explanation:
angle #1 = 23
angle #2 = 90
angle #3 = ?
#1 + #2 + #3 = 180
23 + 90 + ? = 180
180 - (23 + 90) = ?
180 - 113 = ?
? = 67
The radical parts of the two expressions above will be as follows;
a]
^3 sqrt 54=(54)^(1/3)
=(2×27)^(1/3)
=(2)^(1/3)×(27)^(1/3)
=(2)^(1/3)×(3³)^(1/3)
=3(2)^(1/3)
or
3(^3√2)
Hence the answer is 3(2)^(1/3)=3(^3√2)
a] ^3sqrt 128=(128)^(1/3)
=(2×64)^(1/3)
=2^(1/3)×64^(1/3)
=2^(1/3)×(4³)^(1/3)
=2^(1/3)×4^(3×1/3)
=2^(1/3)×4
=4(2)^(1/3)
=4(^3√2)
Answer: 13.6% needed more time but then said no. 25.6% were contacted but said no.
To do this problem, you have to create a tree diagram with all of the possibilities.
The first branch separates with 20% not being contacted and 80% being contacted.
Then, the 80% branch can be broken into 12% saying no and 68% needing more time (multiply by 15% and 85%).
Then, the 68% branch can be broken into 54.4% going and 13.6 not going (multiply by 80% and 20%).
With the tree diagram, just pick the percents that you need.
