Answer:
15
Step-by-step explanation:
Total quantity of clay = 5 pound
Now, Reynolds divides the clay into 1 third pound pieces.
this means each piece of clay weighs = 1/3 pounds
Therefore, number of pieces of clay = Total weight of clay/ weight of each piece
= 5/(1/3) = 15
I think it's C. No matter how large or small you make a triangle, the angles will always have the same measurements. It's only the side lengths that change
Answer:
the three boxes should be filled with
2 8 -12
respectively
Step-by-step explanation:
The general equation of the parabola in this problem is
y = a(x-h)^2 + k
vertex is at (-2, -20), => k=-20, h = 2
so the equation is
y = a(x+2)^2 - 20
To have y-intercept = -12, we set x = 0
-12 = a(0+2)^2 - 20
a(2^2) = 8
a = 2
therefore the equation of the parabola is
y = 2 (x+2)^2 -20 = 2x^2 + 8x - 12
the three boxes should be filled with
2 8 -12
respectively

Answer:
2.389 x 10^5
Step-by-step explanation:
First, write both numbers out. Move the decimal point right however many times the exponent says. For 8.9, we move the decimal right 3 times, and we would move it right 5 times for 2.3.
230000
<u>+ 8900</u>
238900
Now let's convert this to scientific form. The beginning number in scientific form has to be between 1 and 10, so move the decimal point left until you get a number that fits. Here, we will move it 5 times.
2.38900
Because we've moved it left 5 times, we make the exponent 5.
