A sample of pure silicon has a volume of 350cm3 and a mass of826g, what is its density?

Answer:

1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3

2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3

3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12

4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5

5. To put x by itself, you subtract 1 by 4, giving you x<-3

Answer:

The answer is that the cost will be a total of $142.05. That is $125.80 for Watermelon that weighs 185 lbs and $16.25 for 5 lbs of tomatoes.

Step-by-step explanation:

Given: Watermelons are .68 / lb and tomatoes are 3.25 / lb.

Let w = watermelon weight and tomato weight.

An equation would be:

.68w + 3.25t = Total cost

For 185 lb of Watermelon and 5 lbs of tomatoes:

.68(185) + 3.25(5) =

$125.80 + $16.25 = $142.05

Answer:

The length of each part is 3.5 inches.

Step-by-step explanation:

The question states that the bar is 7 inches long, with the two parts being equal lengths.

What you would do to find the length of each bar is doable with simple division. Take 7, and divide it by 2. 2 goes into seven 3 times, which would leave 1. Add a decimal and a zero, bring the zero down, and you get 10. 2 goes into 10 five times, giving you the 5 in 3.5.

1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

The area of Rectangle is length times of width.

Given that the bar is 7 inches long and divided into 2 equal parts.

We need to find the length of one of those parts.

We take the whole bar as a whole number.

The two parts of the bar are considered as parts of the bar.

The seven inches is divided equally.

The length of the bar is seven inches.

We need to divide seven by two to get the length of one part.

When seven is divided by the two we get three point five inches which is the length of the one of the part of the bar.

1/2×7=3.5 inches

The equation which gives the length of the one of the part of bar is 1/2×7=3.5 inches.

Hence, 1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

Answer:

y = 6

Step-by-step explanation:

4y - 46 + y = 4 - 5y + 10

simplify

5y - 46 = 14 - 5y

add 5 y to each side

10y - 46 = 14

add 46 to each side

10y = 60

divide both sides by 10

y = 6

circle=1

rectangle=2

Step-by-step explanation:

The intersection of the plane and the solid has

1. Circular cross section.

2. Rectangular cross section.

3. Triangular cross section.

1. Since the base is circular and the plane through the solid is parallel to it, the base is also round.

As a result, the intersection of the plane and the solid has a Circular cross section.

2. Since the plane through the solid is parallel to it, the side is rectangle is also round.

As a result, the intersection of the plane and the solid has a Rectangular cross section.

3. The intersection of the plane and the solid has a Triangular cross section.

Answer: As "x" increases "y" *decreases*

y as a function of x is not *constant*

Therefore the function is *nonlinear*

For all values of x, the function value y *≥* 0.

The y intercept of the graph is *8*

x=1 function value of y is *5*

The given function is an exponential function and its qualities are explained below.

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

As we can observe in the graph.

The illustration below shows the graph of y as a function of x.

Complete the following sentences based on the graph of the function.

- As x increases, y decreases.

- The rate of change for y as a function of x is not constant, therefore the function is nonlinear.

- For all values of x, the function value y > 0.

- The y-intercept of the graph is the function value y = 8.

- When x = 1, the function value y = 5.
