Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:

Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.

i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:

As time can't be negative hence we will consider:

Hence, grasshopper will land on the ground after 1.5 sec.
Answer:
A) 250 / 8 = 31.25
31.25 x 8 = 250 Know you know that one pancake requires 31.25ml of Milk
31.25 x 4 = 125
So 4 pancakes requires 125ml of Milk
B) 5 / 8 = 0.625
0.625 x 8 = 5 So just like last time, you know that 0.625g of butter is required to make 8 pancakes
0.625 x 12 = 7.5g of Butter
So 12 pancakes requires 7.5g of butter.
Hope this makes sense !
280 mg = 70 Ml
280/70 = 4
50 mL x 4 = 200 mg
200 mg
Answer:
12
