Answer:
304 brass connectors.
Step-by-step explanation:
We have been given that a box filled with brass connectors weighs 5 pounds 4 ounces. The box weighs 8 ounces when empty, and each connector weighs 0.25 ounces.
Since we know that 1 pound equals to 16 ounces.Let us convert weight of box filled with brass connectors from pounds to ounces.
Now we will find weight of brass connectors by subtracting weight of empty box from weight of filled box.
Let us divide 76 by 0.25 to find number of brass connectors in the box.
Therefore, there are 304 connectors in the box.
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:
x = 61
Step-by-step explanation:
These 2 angles are supplementary which means they add up to 180:
2x - 6 + x + 3 = 180
3x - 3 = 180
3x = 183
x = 61
Answer:
see below
Step-by-step explanation:
That is a LOT of questions
complement angles add to 90 suppleent angles add to 180
9) complement = 50 supplelement = 140
13) compl = 40 suppl = 130
14) comp = 45 supple = 135
I think you can do the rest, right?
Answer:
155
Step-by-step explanation:
5*5=25
((5*13)/2)*4=130
130+25=155
