1.5 miles/ .6 hours =  2.5 miles per hour

her walking rate is 2.5 miles per hour

d= r * t

4.5 miles = 2.5 * t

divide each side by 3.5

4.5 /2.5 = t

1.8 = t

t = 1.8 hours

11 am  - 9 am = 2 hours

She will make it to work on time because 1.8  hours < 2 hours

Alexis bought a pyramid-like paperweight for her teacher. The paperweight has a volume of 200 cm3 and a density of 1.5 grams per
Nikolay [14]

Answer:

The density is equal to the weight divided by the volume:

\rho=\dfrac{W}{V}

The paperweight weights 300 grams.

Step-by-step explanation:

The density of the paperweight can be calculated knowing the weight and the volume of this paperweight.

The density is equal to the weight divided by the volume:

\rho=\dfrac{W}{V}

We know that the density of this paperweight is 1.5 grams per cm3, and its volume is 200 cm3.

We can use the formula of the density to calculate the weight:

\rho=\dfrac{W}{V}\\\\\\W=\rho\cdot V=1.5\;\dfrac{g}{cm^3}\,\cdot\;200\; cm^3\\\\\\W=300\;g

The paperweight weights 300 grams.

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. f ( x ) = 9 x 3 + 2 x 2
sladkih [1.3K]

Answer:

2x(2x²+x+1)

Dtep-by-step explanation:

f(x) = 9x³+2x²-5x+4

g(x) = 5x³-7x+4

f(x) - g(x)

= 9x³+2x²-5x+4 - (5x³-7x+4)

= 9x³+2x²-5x+4-5x³+7x-5

= 4x³+2x²+2x

= 2x(2x²+x+1)
