Answer:
the ladder reaches up to 9.75 ft. high
Step-by-step explanation:
a^2+b^2=c^2
plug in the numbers
a^2+49=144
then subtract 49 from 144
a^2=95
then sq 95
a=9.75
9514 1404 393
Answer:
3) y = √10
4) x = 5√2
Step-by-step explanation:
The side ratios of an isosceles right triangle (one of the "special" right triangles) are ...
1 : 1 : √2
So, for some multiplier k, they can be made to match the sides in your triangles.
__
3) 1·k : 1·k : k√2 = √5 : √5 : y
Clearly, k = √5, so ...
y = (√5)(√2)
y = √10
__
4) k : k : k√2 = x : x : 10
k = 10/√2 = (5√2)/2
k = x = (5√2)/2

Answer: They walked 11/12 miles
Step-by-step explanation:
1/4 + 4/6
3/12 + 8/12
11/12
25% because if you simplify the fraction, it would be 1/4 and that is equal to 0.25
