Calculate the density of a rectangular piece of wood from the following data:Length: 25 cm. Width: 10 cm. Height: 4 cm. Mass: 15 g
a.

0.015 g/cm3

c.

0.015 g/ml
b.

10.015 g/ml

d.

None of the above

Answers

Answer 1

Answer: Density is the measure of how a certain volume weighs. So to get the density, we divide the weight by the volume of a certain material. This probem already gave us the weight which is equal to 15 grams. Our next task is to get the volume of the material. This problem gave us the dimensions of the object. Hence the volume is just 1000cm^3 (note cm^3 =ml) The density is then 0.015 g/cm^3.

Answer 2

Answer:

Answer: $\mathbf{a.\ 0.015\text{ g/cm}^3}$

Step-by-step explanation:

Formula for density = $\frac{\text{Mass}}{\text{Volume}}$

As per given , dimensions of a rectangular piece of wood:

Length: 25 cm. Width: 10 cm. Height: 4 cm.

Mass: 15 g

Volume of rectangular piece = Length x width x height

= 25 x 10 x 4 = 1000 cubic cm

Now , density = $(15)/(1000)=0.015\text{ g/cm}^3$

Hence, the correct option is $\mathbf{a.\ 0.015\text{ g/cm}^3}$

Rick used 4-2-3 yards to sew 3-1-2 shirts what is the unit rate of cloth he used in terms of yards per shirt Mathematics 7th grade

Answers

If Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. The unit rate of cloth he used in terms of yards per shirt will be 4/3.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

The unit rate of cloth he used in terms of yards per shirt is found by dividing the 3 1/2 shirts by 4 2/3 yards,

$= 4 (2)/(3) / 3 (1)/(2) \n\n = (14)/(3) / (7)/(2) \n\n = (14)/(3) * (2)/(7) \n\n = (4)/(3)$

Thus, if Rick used 4 2/3 yards of fabric to sew 3 1/2 shirts. The unit rate of cloth he used in terms of yards per shirt will be 4/3.

The non-profit organization you volunteer for is throwing a fundraiser cookout. You are in charge of buying the hamburgers, which cost $3 per pound, and hot dogs, which cost $2 per pound. The meat budget you are given totals $600 dollars. The inequality 3x + 2y less than or equal to 600 represents the possible combinations of pounds of hamburgers (x) and hot dogs (y) you can buy.

Answers

Which of the following represents a solution to the inequality?
200 pounds of hamburgers and 140 pounds of hot dogs
150 pounds of hamburgers and 60 pounds of hot dogs
100 pounds of hamburgers and 240 pounds of hot dogs
240 pounds of hamburgers and 40 pounds of hot dogs

x = hamburger ; y = hot dog
3x + 2x < 600

3(200) + 2(140) = 600 + 280 = 880 No.
3(150) + 2(60) = 450 + 120 = 570 YES.
3(100) + 2(240) = 300 + 480 = 780 No.
3(240) + 2(40) = 720 + 80 = 800 No.
