kilogram

Step-by-step explanation:

The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density.1,000 kg/m3 equals 1 g/cm3. (The cubic centimeter can be alternately called a millilitre or a cc.)

Answer:

Although I'm not entirely sure of the question (sorry lol), any ratio that is 1.5:2 , 6:8 , 9:12 , 12:18 etc would be equivalent to 3 to 4.

Step-by-step explanation:

If you divide both 3 and 4 by 2 you'd wind up with 1.5 ( 3 ) and 2 ( 4 ). When multiplying, you'd get 3x2 = 6 and 4x2=8, 3x3 = 9 and 4x3 = 12 and so on.

Answer:

x = $3

y = $4

Step-by-step explanation:

We need to know the prices of gravel and peas. We can find the price by using equations and graphing them.

Let X be the price of the sand

Be and the price of pea gravel

In the first purchase we have:

[tex]4x + 3y = 24[/tex]

In the second purchase we have

[tex]2x = 6[/tex]

Both relations represent the equation of a line. In the graphic shown, these lines are drawn. In this case the interception between both lines represents the price of each product, and the solution of the problem. You can see that the lines intersect at point (3 4). This means that the price of each bag of sand is $ 3, and the price of a bag of pea gravel is $ 4.

[tex] = -2\dfrac{1}{9} + 4 \dfrac{1}{3} [/tex]

[tex] = -\dfrac{19}{9} + \dfrac{13}{3} [/tex]

[tex] = -\dfrac{19}{9} + \dfrac{39}{9} [/tex]

Answer:

D. 45 students

25+4n=115+2n

     -2n         -2n

25+2n=115

-25         -25

2n=90

2n/2=90/2

n=45

The cost for both bus companies A and B is equal when there are 45 students on the trip. This result is achieved by setting the cost equations of the two companies equal to each other and solving for the number of students.

To solve this problem, we set the cost equations for bus companies A and B equal to each other and solve for the number of students.

For company A, the cost is $25 (rental fee) + $4 per student. For company B, the cost is $115 (rental fee) + $2 per student.

So, the equation becomes: $25 + $4 * number of students = $115 + $2 * number of students.

If you rearrange that equation and solve for the student variable by subtracting $2 * students from both sides and subtracting $25 from both sides, you end up with $2 * students = $90.

This means that the number of students, when divided by $90 and $2, is equal to 45. Thus, 45 is the number of students for the bus cost from both companies to be equal. Therefore, the answer is (d) 45 students.

Answer:

Approximately 201.06 in² of pizza sauce is needed

(if using the approximation π ≈ 3.14, then the answer is 200.96 in²)

Step-by-step explanation:

We assume that the pizza is perfectly circular and that we want to cover the entire surface. We need the formula for the surface area of a circle which is

  A = πr²,

where r is the radius of the pizza.

By definition, the diameter is twice the radius. So the radius of this pizza is half of 16'' = 16 inches, which is 8 in.

Therefore, (using a calculator value for π instead of 3.14 approximation),

  A = π(8 in)² = 64π in² ≈ 201.06 in².

Approximately 201.06 in² of pizza sauce is needed.

If you are need to use the approximation π ≈ 3.14, then the answer is 200.96 in²

Answer:

201.06 square inches

Step-by-step explanation:

We need to cover the whole surface area of the pizza so if the pizza is a circular one (using the typical shape), then we can use the formula of the area of a circle.

Area of a circle = pi * r^2

We are given the diameter of the circle to be 16 inches so its radius will be 8 inches.

Substituting this value of radius in the formula to get:

[tex]\pi r^2[/tex] = [tex]\pi (8)^2[/tex] = [tex]201.06[/tex]

Therefore, about 201.06 square inches of pizza sause is needed to cover the pizza.

The property for 8 +0 = 8, Additive Identity Property

Answer: 25%

Step-by-step explanation:

Given : The price of a video game was reduced from $60 to $45.

i.e. Previous price = $60

New price = $45

Reduction in price = Previous price -New price

= $60 - $45 = $15

Then, the percentage was the price of the video game reduced :-

[tex]\dfrac{\text{Reduction in price}}{\text{Previous price}}\times100\\\\=\dfrac{15}{60}\times100=25\%[/tex]

Hence, the percentage was the price of the video game reduced = 25%

25% was the price of the video game reduced.

Step-by-step explanation:

Given :

Previous Price of the video game = $60

Present Price of the video game = $45

Calculation :

Let previous price of the video game be 100% than,

[tex]= \dfrac{45\times 100}{60}[/tex]

=  75%

Reduced Percentage = 100 - 75 = 25%

Therefore,  25% was the price of the video game reduced.

Answer:

B= -4.3 or -13/3

The IQ score that aligns with a z-score of 2.33 in a normal distribution having a mean of 100 and a standard deviation of 15 is approximately 135.

The IQ score that corresponds to a z-score of 2.33 can be found using the z-score equation. In this equation, z is equal to (X - μ)/σ, where X is the value we're trying to find, μ is the mean, and σ is the standard deviation. Given that the mean (μ) is 100 and the standard deviation (σ) is 15, we can plug these values into the equation along with the z-score of 2.33 to solve for X. Through rearrangement of the z-score equation, X = zσ + μ. Substituting a z of 2.33, σ of 15, and μ of 100, gives X = (2.33*15) + 100 = 134.95. Hence, an IQ of approximately 135 corresponds to a z-score of 2.33 on a normally distributed IQ test.

Answer:

160.0 cm²  

Step-by-step explanation:

R = 42 cm; s = 44 cm

1. Central angle θ (working in radians)

θ = s/R

θ = 44/42

θ = 22/21

===============

2. Area of sector

A = ½R²θ

A = ½(42)²(22/21)

A = ½(42×21×2)(22/21)

A = 924 cm²

===============

3. Area of triangle

A = ½R²sinθ

A = ½(42)²sin(22/21)

A = ½ ×1764 × 0.8662

A = 764.0 cm²  

===============

4. Area of segment

Area of segment = Area of sector – area of triangle

= 924 – 764.0

= 160.0 cm²

The area of segment is [tex]\boxed{160{\text{ c}}{{\text{m}}^2}}.[/tex]

Further explanation:

The formula of angle can be obtained as follows,

[tex]\boxed{\theta= \frac{{{\text{arc}}}}{{{\text{radius}}}}}[/tex]

The formula for area of sector can be expressed as follows,

[tex]\boxed{{\text{Area of sector}} = \frac{1}{2}{r^2}\theta }[/tex]

The formula for area of triangle can be expressed as follows,

[tex]\boxed{{\text{Area of triangle}} = \frac{1}{2}{r^2}\sin \theta }[/tex]

Given:

The radius of the circle is [tex]42{\text{ cm}}.[/tex]

The length of an arc is [tex]44{\text{ cm}}.[/tex]

Explanation:

The radius of the sector is [tex]42{\text{ cm}}[/tex] and the length of an arc is [tex]44{\text{ cm}}.[/tex]

The angle can be obtained as follows,

[tex]\begin{aligned}\theta&= \frac{l}{r}\\&=\frac{{44}}{{42}}\\&= \frac{{22}}{{21}}\\\end{aligned}[/tex]

Area of the triangle can be obtained as follows,

[tex]\begin{aligned}{\text{Area}}&= \frac{1}{2}{r^2}\sin {{\theta }}\\{\text{ }}=&\frac{1}{2}{\left( {42} \right)^2}\sin \left( {\frac{{22}}{{21}}} \right) \\&=882 \times 0.8662\\&=764{\text{ c}}{{\text{m}}^2}\\\end{aligned}[/tex]

Area of sector can be obtained as follows,

[tex]\begin{aligned}A&= \frac{1}{2}{r^2}\theta\\&= \frac{1}{2} \times {\left( {42} \right)^2} \times \left({\frac{{22}}{{21}}} \right) \\&= 924{\text{ c}}{{\text{m}}^2}\\\end{aligned}[/tex]

The area of segment can be obtained as follows,

[tex]\begin{aligned}{\text{Area of segment}}&= {\text{Area of sector}} - {\text{Area of triangle}}\\&= {\text{924}} - 764\\&= 160{\text{ c}}{{\text{m}}^2}\\\end{aligned}[/tex]

Answer:

NO

Step-by-step explanation:

Because that just means they started off with 0

The error in the table is that the "total" value for miles = 40 and gallons = 8 is incorrect.

The error in the given ratio table is that the values in the "total" row are not calculated correctly based on the provided "miles" and "gallon" values.

The values in the "total" row do not match the sum of the "miles" and "gallon" values for each corresponding column.

When miles = 0 and gallons = 0, the total should also be 0.

When miles = 10 and gallons = 2, the total should be 12.

When miles = 20 and gallons = 4, the total should be 24.

When miles = 30 and gallons = 6, the total should be 36.

When miles = 40 and gallons = 8, the total should be 48 (not 49).

When miles = 50 and gallons = 10, the total should be 60.

The error occurs in the row where miles = 40 and gallons = 8. The "total" value is listed as 49 instead of the correct value, which should be 48. So, the error in the table is that the "total" value for miles = 40 and gallons = 8 is incorrect.

-2x+8-8 < 12-8 ... subtract 8 from both sides

-2x < 4

-2x/(-2) > 4/(-2) ... divide both sides by -2; sign flips

x > -2

To graph this, plot an open circle at -2 on the number line. Shade to the right of this open circle. The open circle means "this value is not included in the shaded solution region". The sign flips in the second to last step because we divided both sides by a negative number.
