The aggregate volume of the two rectangular prisms is 330 cubic cm.

The base's area multiplied by the height gives the rectangular prism its volume. So the formula for a rectangular prism's volume is as follows. Using cubic units, the volume of a rectangular prism = length × breadth × height

The volume is going to be the addition of two volumes.

We are going to divide the shape into two.

Volume = length × breadth × height

Section A and section B

Volume = length × breadth × height

Volume of section A is = 2 × 10 × 9

Volume of section A = 180 cm³

Volume = length × breadth × height

Volume of section B is = 3 × 5 × 10

Volume of section B = 150cm³

Total volume = volume of section A + volume of section B

Total volume = 180cm³ + 150cm³

Total volume = 330cm³

Answer:

d) B => b. 0

Step-by-step explanation:

Now we have to,

→ find the y-intercept of the line.

Formula we use,

→ y = mx + b

→ b = y-intercept

Then the y-intercept is,

→ y = mx + b

→ y = (-2/3)x + 0

→ [ b = 0 ]

Hence, the y-intercept is 0.

What is graph of a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.

equation: a statement that two expressions having variable- and/or number-filled expressions are equivalent. Since equations are essentially questions, the search for a way to respond to them has spurred the development of mathematics.

Here,

Let's assume that the pipelines in this instance are "a" to drain the water in 6 hours, "b" to fill the water on its own in 4 hours, and "c" to fill the water in 5 hours.

Therefore, if "a" can empty it in 6 hours, it has only completed 1/6 of the task in that time. In 6 hours, "a" would have completed 6/6 or 1 whole, the entire task, and the cistern would have been fully filled, but in 1 hour, it has only accomplished 1/6 of that.

In an hour, "b" has completed barely a quarter of the task.

In that case, "c" has only completed 1/5 of the task in an hour.

Now, assuming it took "x" hours, if "a," "b," and "c" are running, and "a" is draining while b & c filling it up.

The cistern must be filled in "x" hours, thus after 1 hour, all three have completed only 1/x of the task.

well, let's add their rates, to see what we get then.

=> 1/4 + 1/5 -1/6= 1/x

=> 15 + 20 - 10 / 60 = 1/x

=>35/60 =1/x

=> x=60/35

=>1.71 hours

Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.

The value of n after solving the given equation comes to 75.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.

A variable, coefficients, and constants make up an algebraic equation in most cases.

So, we have the equation:

n/(200 - n) = 3/5

Now, solve for x as follows:

n/(200 - n) = 3/5

5n = 600 - 3n

8n = 600

n = 600/8

n = 75

Therefore, the value of n after solving the given equation comes to 75.

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -8 and the y-intercept is (0, 10), so the equation is y = -8x + 10.

The equation of a parabola with a directrix at y = −3 and a focus at (5, 3) is y=1/12(x - 5)² .

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

Given that the directrix of parabola is at y=-3.

Focus at (5, 3)

parabola with equation  (x - h)² = 4p(y - k)

p = 3 because the distance from the focus to the directrix is 6 and p = 6/2.

The vertex (5, 0)

Substitute h as 5 and k as 0.

(x - 5)² = 4(3)(y - 0)

(x - 5)² = 12y

Divide both sides by 12

y=1/12(x - 5)²

Hence,  the equation of a parabola with a directrix at y = −3 and a focus at (5, 3) is y=1/12(x - 5)² .

(ii) Substituting x=sin²(θ), we have the quadratic ...

  2x² +x -1 = 0

The quadratic formula gives the solutions as ...

  x = (-1 ±√(1 -4(2)(-1)))/(2(2)) = (-1±3)/4 = -1, 1/2

The value of sin(θ) is the square root of these values. √-1 is imaginary, so does not give us any solutions. √(1/2) = (±√2)/2, corresponding to ...

  sin(θ) = (±√2)/2

  θ ∈ {45°, 135°, 225°, 315°}

(i) Substituting as suggested above, we have ...

  [tex]\dfrac{\sin x\tan x}{1-\cos x}=1+\dfrac{1}{\cos x}\\\\\dfrac{\sin^2 x}{\cos x(1-\cos x)}=\qquad\text{substitute for $\tan x$}\\\\\dfrac{1-\cos^2 x}{\cos x(1-\cos x)}=\qquad\text{substitute for $\sin^2 x$}\\\\\dfrac{1+\cos x}{\cos x}=1+\dfrac{1}{\cos x}\qquad\text{cancel the common factor}\\\\1+\dfrac{1}{\cos x}=1+\dfrac{1}{\cos x}\qquad\text{Q.E.D.}[/tex]

The equation of a line is given by y = mx + c

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 120.

The slope of a line that passes through (4,440) and (6,560) is 0.676.

We have,

The equation of the line y = mx + c.

The line passes through (4,440) and (6,560).

This means,

We can find the slope using the coordinates (4,440) and (6,560).

Slope = m

The addition equation is 93 - 67 = 26 in the number line.

What is number line?

A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.

The entire question is depicted in the picture that is attached.

Richard added 26 to 67 by first marking point 67 on the line, then adding 2 tens and 2 threes until he reached 93 as opposed to subtracting 67 to 93 by subtracting 6 tens and 7 ones starting at point 93, which results in 26.

Take note that 26 is equal to 10 plus 10 plus three additional times.

To verify his work, we add the following: 67 + 26 = 93, which is also written as 93 - 67 = 26.

Hence the addition equation is 93 - 67 = 26.

Markup = ((Selling price - Cost price) / Cost price) x 100%

In this case, the cost of materials is $80 and the selling price is $150, so the markup is:

Markup = ((150 - 80) / 80) x 100%

Markup = (70 / 80) x 100%
