The volume of the composite figure is 12 cubic in.

How to calculate the Volume of Composite Shapes?

Composite shapes have a volume that is made up of basic shapes. We can calculate the volume of the composite shapes using the steps listed below:

Step 1: Break down the compound shape into different components.

Step 2: Determine the volume of each basic shape.

Step 3: Combine the volumes of all the basic shapes.

Step 4: Write the solution in cubic units.

Firstly we can divide the figure into two rectangular prisms A and B. Then add these two to total volume the volumes of each prism.

The volume of prism A = length × width × height

V = 4 * 2 * 1

V = 8 cubic in.

The volume of prism B = length × width × height

V  = 1 * 2 * 2

V = 4 cubic in.

Total volume = volume of prism A + volume of prism B

= 8 cubic in + 4 cubic in

= 12 cubic in

Hence, the volume of the composite figure is 12 cubic in.

Answer:

[tex]6\pi[/tex]

Step-by-step explanation:

There's two things to note here, we're dealing with a semi-circle and also a semi-circle that has some area taken out of it.

The area of a circle can be calculated using the formula: [tex]A=\pi r^2[/tex] where "r" is the radius, equal to half the diameter.

Since we're dealing with the semi-circles, we can just divide this area by two to get: [tex]A=\frac{\pi r^2}{2}[/tex]

Now as noted, we have some of the area taken out, but fortunately it's just another semi-circle. We can simply calculate the area of the entire semi-circle, and then calculate the area of the semi-circle inside and subtract them.

So the diameter of the entire thing is just 8 ft, so the radius is half of this, equal to 8 ft. That means the area is: [tex]A=\frac{\pi (4)^2}{2}=A = \frac{\pi * 16}{2} = 8\pi[/tex]

One mistake that may be made here, is assuming the radius of the smaller semi-circle is just two, as provided in the image. It's actually the radius of the inner semi-circle plus two which gives us the radius of the outer circle, of 4 feet. Now luckily in this case, it actually still results in 2 ft (since 2 + 2 = 4), but in other examples, that may noe be the case.

So now let's calculate the area of the inner semi-circle: [tex]A=\frac{\pi (2)^2}{2}=2\pi[/tex]

Now let's just subtract the areas: [tex]8\pi - 2\pi = 6\pi[/tex], so the area is 6 pi

The domain of the relation include the following: C. {-5, -2, 0, 1, 4}.

In Mathematics, the horizontal extent of any graph of a function represents all domain values and they are always read and written from smaller to larger numerical values, and from the left of the graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain:

Domain = {-5, -2, 0, 1, 4}.

Answer: Janelle can fill 6 feeders.

Step-by-step explanation:

To find the number of feeders Janelle can fill, we need to divide the total amount of bird food she has by the amount of bird food each feeder can hold.

First, let's convert the total amount of bird food from cups to half-cups:

3 cups / 2 = 6 half-cups

So, Janelle has 6 half-cups of bird food, and each feeder can hold 1 half-cup.

Therefore, she can fill:

6 half-cups / 1 half-cup per feeder = 6 feeders.

So, Janelle can fill 6 feeders.

The measure of a from the triangle ATD is 27 units. Therefore, the option B is the correct answer.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

From the given triangle ADT, ∠A=46°, ∠D=84°, AT=37, AD=t and TD=a.

By angle sum property,

∠A+∠D+∠T=180°

46°+84°+∠T=180°

130°+∠T=180°

∠T=50°

sin46°/a=sin84°/37=sin50°/t

0.7193/a=0.9945/37=0.7660/t

0.7193/a=0.9945/37

0.9945a=0.7193×37

0.9945a=26.6141

a=26.6141/0.9945

a=26.76

≈27

0.9945/37=0.7660/t

0.9945t=0.7660×37

0.9945t=28.342

t=28.342/0.9945

t=28.5

Step-by-step explanation:

3.1 The cash price of the NISSAN NP300 is R221,180 (incl. VAT).

3.2. it would take approximately 6.67 years to pay off the vehicle through instalments.

A deposit of approximately R22,282.70 would be needed if the financing plan requires a 10% deposit

3.1 The cash price of the NISSAN NP300 is R221,180 (incl. VAT).

3.2 The given information does not explicitly state the number of years for the instalment plan, but it does provide the number of months (80) and the total payment amount (R303,007). Assuming a monthly payment plan, we can calculate the number of years as follows:

Number of years = Number of months / 12

Number of years = 80 / 12

Number of years ≈ 6.67 years

So it would take approximately 6.67 years to pay off the vehicle through instalments.

To calculate the deposit needed, we need to subtract the residual amount from the total cash price. From the given information, the total payment is R303,007 and the residual is R80,180, so:

Cash price = Total payment - Residual

Cash price = R303,007 - R80,180

Cash price = R222,827

So the cash price is slightly higher than the advertised price of R221,180, likely due to financing fees or interest. To determine the deposit needed, we can assume a specific percentage of the cash price that must be paid upfront. For example, if the deposit required is 10% of the cash price, then:

Deposit = 0.1 x Cash price

Deposit = 0.1 x R222,827

Deposit = R22,282.70

So a deposit of approximately R22,282.70 would be needed if the financing plan requires a 10% deposit.

The statement that correctly defines continuous and discrete quantitative variables is:

"A continuous variable can take on any real number value within some range, whereas a discrete variable come in countable units."

A variable is a quantity that may assume any one of a set of values.

This means that a continuous variable can take on any value within a certain range, which could be infinite, and that it can have decimal values. In contrast, a discrete variable has specific values that are separate and countable, such as integers or categories. For example, the height of individuals is a continuous variable, while the number of siblings someone has is a discrete variable.

THE ANSWER TO YOUR QUESTION IS C.

The sum of the capitals would be $530400.

The formula to calculate the simple interest is -

I = PRT/100

Given is that a capitalist has two capitals that differ in $221,000. The largest of them imposes it at 20% per year and the smallest at 16% per year, so after 3 years, the amount produced by the largest is double what the smallest produces.

We can write the amount produced by largest as -

A = P(1 + rt)

A = 221000(1 + 0.2 x 3)

A = 221000 x 1.6

A = 353600

Amount generated by smallest -

a = 353600/2

a = 176800

Their sum would be -

A + a = 530400

Answer:

Step-by-step explanation:

Generally an equation which will be true for all values of x have some statement which can be simplified into another state which will always be true.

So for example: [tex]x+4=x+4[/tex], is kind of a bit obvious to tell it's going to be true for all values as the two expressions have the same exact terms, but we can subtract "x" from both sides leading us to the statement: [tex]4=4[/tex] which is always true.

One important thing to note is you must be cautious at times, for example: [tex]\frac{x-2}{x-2}=\frac{x-2}{x-2}[/tex] may seem to be true for all values, and x-2 over x-2 is the same thing, so it simplifies to one and same thing on the right side: [tex]1=1[/tex] thus the statement should be true for all values right? Not completely, it's true for most values, except for x=2, and this is because 1=1 isn't exactly the same expression. In the original fraction the denominator has an x-2, and if we plug in x=2, we get 2-2 resulting in division by one, which of course isn't definable. So that's just one important thing to note as simplifying expressions may result in expressions that look equal, but are slightly different in a way.
