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.

A customer pays $1,100 in state taxes on a newly purchased car. What is the value of the car if state taxes are 8.9% of the valu
Ganezh [65]
The taxes are figured as follows:  0.089(value of car)

Here the taxes are 0.089(value of car) = $1100.

Divide both sides of this equation by 0.089 to determine the value of the car.

value of car = $12359.55, or approx $12360.

- 8x + 44 ≥ 60
- 8x ≥ 60 - 44
- 8x ≥ 16
x ≤ - 2

- 4x + 50 < 58
- 4x < 58 - 50
- 4x < 8
x > - 2

Now put the two together. Logically, these two answers since a number cannot be both less than AND greater than - 2. 

Your answer should be no solution.

pogonyaev

<u>Answer:</u>

66 pictures

<u>Step-by-step explanation:</u>

180 ÷ 3 = 60      60 x 2 = 120

120 = 2/3. He took <em><u>120 pictures on the first day </u></em><em><u>of his vacation.</u></em>

120 ÷ 4 = 30    30 x 1 = 30

30 = 1/4. <em><u>He took </u></em><em><u>30 pictures of landscapes</u></em>

120 ÷ 10 = 12     12 x 3 = 36

0.3 = 36. <em><u>He took </u></em><em><u>36 pictures of people.</u></em>

36 + 30 = 66 pictures.

<em><u>He took 66 pictures of landscapes and people.</u></em>

Alejandro surveyed his classmates to determine who has ever gone surfing and who has ever gone snowboarding. Let A be the event
victus00 [196]

Answer:

{A and B are independent events}, P(A|B)=P(A)=0.16

Step-by-step explanation:

First of all we need to know when does two events become independent:

For the two events to be independent,  P(A|B)=P(A) that is if condition on one does not effect the probability of other event.

Here, in our case the only option that satisfies the condition for the events to be independent is  P(A|B)=P(A)=0.16.. Rest are not in accordance with the definition of independent events.
