Answer:
a) 1/24 do total
Step-by-step explanation:
We have that:
The total is 1.
The first friend gets 1/4 of the total.
The second friend gets 1/3 of the total
The third friend gets 3/8 of the total.
The remaining is x.
So
The least common multiple between 4, 3 and 8 is 24. So
So the correct answer is:
a) 1/24 do total
Answer:
c
Step-by-step explanation:
a: 9/5 and 19/10 are already in simplest form
b:25/35 can be simplified to 5/7 if you divide each side by 5 and 20/24 can
be simplified to 5/6 if you divide each side by 4
c: both 15/10 and 21/14 can be simplified to 3/2
d: 4/6=2/3 and 10/16=5/8
The ratio up to forward is 2:5 (For every two feet the ramp goes up it also goes 5 feet forward).
<span>If this ratio remained constant and we went x feet up and 22.5 feet forward, then x:22.5=2:5,

</span><span>5x=2·22.5,
</span>
5x=45,
x=45÷5,
x=9.
Answer: 9 feet up

By the Pythagorean Theorem:
24^2+d^2=25^2
576+d^2=625
d^2=49
d=√49
d=7 ft
