Answer:

Find the cube's volume first (because it's the simplest figure) by using the formula;

(Formula for vol. of cube)

V = [tex]s^{3}[/tex]

Where 's' stands for one side of the cube raised to the power of three.

or

V = w · l · h

Where 'w' stands for the width, 'l' stands for the length, and 'h' stands for the height.

Plug in the values you know since they literally give it to you (I'll be using the formula [tex]s^{3}[/tex]);

V = [tex]s^{3}[/tex]

V = 3^3 → (The symbol ' ^ ' means to the power of.)

V = 27, is the volume of the cube.

Now we find the volume of the pyramid using the formula;

(Formula for vol. of pyramid)

V = (l · w · h) · 1/3

Where 'l' means the length, 'w' the width, and 'h' the height whereas the 1/3 is just dividing the product of those three by 3.

Plug in the values you know using both the lengths from the cube and pyramid.

Length = 3

Width = 3

Height = 3(we won't use)

Height = 4

Use these to figure out the volume for the pyramid.

V = (l · w · h) · 1/3

V = (3 · 3 · 4) · 1/3

V = 36 · 1/3

V = 36/3

V = 12, is the volume of the pyramid.

Add your volumes:-

27(cube vol.) + 12(pyramid vol.)

= 39 is the volume for this whole solid, your answer is D.

The equation which shows how to find the height in inches of based on the screen's width is; h=2w

According to the taks content!

The ratio of the height of the screen to its width is 18:9.

On this note, it follows that;

h/w = 18/9

By making the h the subject of the formula;

h = 18w/9

h = 2w.

The composite figure includes a rectangle and trapezoid

The area of the composite figure is 810.5cm².

From the complete question, we have the following parameters:

Shapes: Rectangle and trapezoid

The area of the rectangle is:

Area = Length × Width

So, we have:

Area = 15 × 23

Area  = 345cm²

The area of the trapezium

Area = 0.5 × (a + b) ×h

So, we have:

Area = 0.5 × (15 + 34) × 19

Area = 0.5 × 49 × 19

Area = 465.5cm²

Add both areas to calculate the area of the composite figure

Total area = 345cm² + 465.5cm²

Total area  = 810.5cm²

Hence, the area of the composite figure is 810.5cm².

$30 dollars is the principal.

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

The given equation 3(x+10)+6=3(x+12) has infinitely many solutions.

We have the following expression

[tex]3(x+10)+6=3(x+12)[/tex]

We must rewrite both sides of the equation.

For this, we use the distributive property.

A (B + C) = AB + AC

We have then

3(x+10)+6=3(x+12)

Adding like terms we have

3x+30+6=3x+36

3x+36=3x+36

We observe that we have two equal equations.

Therefore, the equations intersect for any value of x.

Therefore, the equation has infinite solutions.

Step-by-step explanation:

Here we know that T is the midpoint of SU.

Therefore, we know ST and TU are equal.

Setting their values equal, we get:
x+3 = 4x

Then we isolate x by subracting x from both sides:

3=3x

Finally we divide by 3:

1=x

Now we can solve for TU:

Answer: 2x+5y=50

Step-by-step explanation:

x=number of 2-ounce weights

y=number of 5-ounce weights

Because of this you will write the total weight (50) is equal to __. On the other end you will multiply the possible number of 2-ounce weights to 2 because this will give you the weight for the 2 ounce. The same is done for the 5-ounce weights. Once you combine both of them you would get the total weight. Which is why 2x+5y=50 is the answer.

**Your line isn't clearly shown on point with the grid**

If you want this in the slope-intercept form then here it is:

Slope-intercept formula: y=mx+b

Your coordinates: (-3,2) and (1,10)

To find the slope (which is the "m" in the formula) you need to do this formula:

y2 - y1 / x2 - x1 =

(The 2's and 1's should be subscript)

10-2/1-(-3) = 8/4

8/4=2

The slope should be 2

Formula right now: y=2x+b

You need to find the y-intercept:

That should be a point on the y-axis.

(0,n) **N is used for a variable since we don't have a number yet.

In your coordinate plane, (0,4) is your y-intercept.

When writing the y-intercept in the formula don't write a coordinate write the "y"

Lucas's car dealerships' expected revenue over the next 3 days is $6800

The expected revenue is calculated using the following formula of expected value

[tex]E(x) = \sum x * P(x)[/tex]

The data elements on the table are represented as:

Days        Revenue

0              3000

1               1800

2              1300

3               800

So, we have:

E(x) = 0 * 3000 + 1 * 1800 + 2 * 1300 + 3 * 800

Evaluate the sum of the products

E(x) = 6800
