Step-by-step explanation:

All linear dimensions are in ft, and all areas are in ft².

Pyramid:

Lateral area: 4 × 6 × 5 / 2 = 60

Base area: 6 × 6 = 36

Total surface area: 96

Hidden surface area (the square base): 36

Actual surface area in the composite solid: 60

Square prism:

Lateral area: 4 × 20 × 6 = 480

Base area: 2 × 6 × 6 = 72

Total surface area: 552

Hidden surface area (both square bases): 72

Actual surface area in the composite solid: 480

Cube:

Total surface area: 6 × 6 × 6 = 216

Hidden surface area (one base): 36

Actual surface area in the composite solid: 180

The surface areas above are for each of the above solids if each were free standing and unattached to other solids.

The way the three components are above, you must deduct some areas of bases (as shown above in the actual surface areas) since they are internal.

Pyramid actual visible area: 60

Square prism actual visible area: 480

Cube: 180

Answer:

The statement which is NOT true about the equation y = -3 is

It is perpendicular to the equation y = 1/3x + 2 ⇒ C

Step-by-step explanation:

Let us revise the facts of the horizontal line:

∵ The equation of the line is y = -3

→ Which means the value of y = -3 at any value of x

∴ The line is horizontal

∴ Its slope = 0

∵ The horizontal line is parallel to the x-axis

∴ The line does not intersect the x-axis

∴ The true statements are:

The statement which is NOT true about the equation y = -3 is

It is perpendicular to the equation y = 1/3x + 2

Answer:

The amount Martha deposited in checks is $150

The amount Martha deposited in cash is $100

The total deposit is $175

Step-by-step explanation:

Since Total deposit (T) = currency (C) + coins + check (Ck) - cash received (Csh)

T = C + Ck - Csh.  (1)

Given that cash received (Csh) = $75,coins = 0 and the checks deposited totaled $50 less than twice the currency amount. So,

Ck = 2C - $50   (2)

Also, total deposit was $25 more than the check amount. So,

T = Ck + $25  (3)

Substituting equation (2) into (1), we have

T = C + Ck - Csh

T = C + 2C - $50 - Csh

T = 3C - $50 - $75

T = 3C - $125   (4)

Substituting equation (2) into (3), we have

T = Ck + $25

T = 2C - $50  + $25

T = 2C - $25  (5)

Equating equations (4) and (5), we have

3C - $125 = 2C - $25

Collecting like terms, we have

3C - 2C = $125 - $25

C = $100  

Substituting C into (2), we have

Ck = 2C - $50  

Ck = 2($100) - $50  

Ck = $200 - $50

Ck = $150

We now compute T

T = C + Ck - Csh.

T = $100 + $150 - $75.

T = $250 - $75

T = $175

So, the amount Martha deposited in checks is $150

The amount Martha deposited in cash is $100

The total deposit is $175

The Surface Area of Prisms are shown below.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

We have,

1. Surface area of cuboid

= 2(lw+ wh + lh)

= 2(144 + 204 + 96)

= 888 in²

2. Surface Area of Cylinder

= 2πrh

= 2,549.68 mm²

3. SA of Triangular prism

= 2 bh + (a+ b+ c)H

= 154.337 cm²

4. SA of Trapezoidal prism

= (b1 + b2)h + PH

= (5+ 19)12.1 + (8+ 19+ 8 + 19)14

= 290.4 + 756

= 1,046.4 ft²

5. SA of Cuboid

= 324 m²

6. SA of Triangular prism

= 1274.86 yd²

The volume of the vase when the crystal itself has no thickness will be 240 inches³.

The volume of the vase when the crystal itself has no thickness will be calculated thus:

V = Bh

V = (4in × 5in) × 12

V = 240 inches³

When the crystal is half an inch thick on each of the sides and on the bottom, the volume will be:

= 1/2 × 240 inches ³

Answer:

Martha is wrong.

Step-by-step explanation:

Let the cost of the house is C.

Payment by Ranee = 40% of the cost

=40% of C

=[tex]\frac{40}{100}\times C[/tex]

=0.40 C

Payment by Susan = 0.35 of the cost

=0.35 C

Combined payment by Ranee and Susan = 0.40C + 0.35C=0.75C

The remaining payment will be done by Martha.

So, the remaining payment = C- 0.75C=0.25 C

Hence, Martha will have to pay 0.25 of the cost or 25% of the cost.

So, Martha is wrong.

Using the table, we will see that the function is:

t(l) = 3*l

Here we only have a table to work with, so we need to use that.

In the table, we can see the pairs:

So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.

From that we can conclude that the function will be:

t(l) = 3*l

Hence, in this case, it is concluded that the correct answer is "N = 618 - n x 7"

Step-by-step explanation:

Considering the situation described above, the explicit formula that shows the number of ice cream tickets remaining at the end of the day, after n number of days is "N = 618 - n x 7."

This is based on the idea that each day of the ice cream ticket is defined as 7 tickets taken.

Thus the ticket listing for each day is described as

Day 1. 618 - 7 OR 618 - 1 × 7;

Day 2. 618 - 14 OR. 618 - 2 × 7;

Day 3. 618 - 21 OR 618 - 3 × 7;

Therefore, from this illustration above, the formula needed is: "N = 618 - n x 7."

Answer:

B.

Step-by-step explanation:

-(4 - 3) = -1.

If by 22 you mean 2^2 ( 2 squared) then it is B. -22 + 3 = -1.
