Answer:
Option E.
Step-by-step explanation:
Let the intended length of Rebecca's swimming is = x units
and we assume the length of the pool = l units
Now it is given in the question that " She covers one fifth of her intended distance "
That means distance covered = 
" After swimming six more lengths of the pool she had covered one quarter of her intended distance"
So 


x = 20×(6l)
x = 120l
Therefore, Rebecca has to complete 120 lengths of the pool.
Option E is the answer.
Answer:
They are parallel because they have the same slope of −2.
Step-by-step explanation:
got it right on the test, it is correct
Answer:
B
Step-by-step explanation:
Here, we simply want to know who will reach the 6-foot mark sooner
Mathematically, we need to get the slope from the graph
Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds
So what this mean is that, in 4 seconds, the 6 ft mark will be reached
This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs
Now compare this with what Stephano has, which is 2.25 ft/ s
we can see that stephano is traveling at a better speed and will reach the 6 ft mark first
So the correct option is B
The question is Let h(x)=2x+5 and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
the answer
</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12
</span>h(g(1.5))= 12
Answer:
0.68L per dispenser
Step-by-step explanation:
Big bottle contain 213L of soap.
Big bottle will fill 312 dispensers.
This means 1 each dispenser can take 213/312 litres = 0.68L per dispenser.
