A student measures the mass of an 8 cm^3 block of confectioner’s (powdered) sugar to be 4.49 grams. Determine the density of pow

melomori [17]

Answer:

The density of powdered sugar is $0.561 g/cm^3$

Step-by-step explanation:

We are given that A student measures the mass of an 8 cm^3 block of confectioner’s (powdered) sugar to be 4.49 grams

Mass of block of confectioner’s (powdered) sugar = 4.49 grams

Volume of block = 8 cubic cm

We are supposed to find the density of powdered sugar.

So, $Density = \frac{Mass}{Volume}$

$Density = \frac{4.49}{8}$

Density = $0.561 g/cm^3$

Hence the density of powdered sugar is $0.561 g/cm^3$

The parabola $y = ax^2 + bx + c$ is graphed below. Find $a+b+c$. (The grid lines are one unit apart.)

Ann [662]

If $x=0$ , then $y=a\cdot0^2+b\cdot0+c=5$ , so $c=5$ .

If $x=1$ , then $y=a\cdot1^2+b\cdot1+c=2$ , so $a+b+5=2$ or $a+b=-3$ .

If $x=2$ , then $y=a\cdot2^2+b\cdot2+c=1$ , so $4a+2b+5=1$ or $2a+b=-2$ .

We have

$a+b=-3\implies -a-b=3$

$(2a+b)+(-a-b)=-2+3$

$\implies a=1\implies b=-4$

So we end up with

$a+b+c=1+(-4)+5=\boxed{2}$
