Mahalia can make a total of 18 napkins using the fabric which she has bought.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given that,

She has 12 inches wide and 6 yards long fabric.

Since 1 yards = 36 inches.

So,

6 yards = 6 × 36 = 216 inches.

Now,

The total surface area of napkins ⇒ 12 × 216

⇒ 2592 inch²

Area for 1 napkin = 1 foot × 1 foot

Since 1 foot = 12 inches

So,

Area for 1 napkin = 12 × 12 = 144 inch²

Number of napkins can be made = The total surface area of napkins / Area for 1 napkin

Number of napkins that can be made = 2592 inch² / 144 inch²

⇒ 18

Hence "Mahalia can make a total of 18 napkins using the fabric which she has bought".

Answer:

If a new car was purchased for a cost of $16,183.11, and a down payment of 10% of the value was made, the initial payment was $1,618.31.

Thus, the remaining amount to be financed is $14,564.79. It will be financed in 4 years, at an annual interest rate of 11.5%, for four years. Thus, the total interest will be 46% (11.5 x 4), to be distributed among the 4 years of the financing. Then, the total amount to be paid will be $21,264.59, which will be paid in 48 equal monthly payments of $443.01 (21,264.59 / 48).

Answer:

h < 4

Step-by-step explanation:

Simplify both sides

-8h + 16 > -3h - 4

Add 3h to both sides

-5h + 16 > -4

Subtract 16 from both sides

-5h > -20

Divide both sides by -5

-20 divided by -5 = 4

Since you divided by a negative number, you change the inequality sign to < instead of >

Answer:

Step-by-step explanation:

From the given information.

suppose a multiple choice test consists of 5 questions, each with 4 possible answers of which 1 is correct.:

So, we can now suggest that a person can answer each question in 4 different ways given that there are 5 different questions.

Thus, the  students can check off one answer to each question in [tex]4^5 \ different \ ways[/tex]

= 4 × 34 × 4 × 4 × 4

= 1024 different ways.

From the 4 possible answers, since 1 will be correct, definitely 3 other answers will be incorrect.

Thus, the number of ways a student can check off one answer to each question and get all the answers wrong is = 3⁵

= 3 × 3 × 3 × 3 × 3

= 243 ways

Answer:

[tex]\huge\boxed{\boxed{12x+28}}[/tex]

Step-by-step explanation:

Hello.

The Distributive Property states that

a(b+c)=ab+ac, where a, b, and c can be constants (numbers) or variables (letters).

Now that we know the formula, it's time to simplify! :)

The expression is:

4(3x+7)

Multiply 4 times 3x and 4 times 7:

4×3x=12x

4×7=28

Put the terms together:

12x+28

Can we simplify this expression? No, because 12x and 28 are not like terms.

And we're done!

Answer: Approximately 0.78388 seconds

==========================================

Explanation:

Plug in t = 0 to find that

h = -16t^2 - 64t + 60

h = -16(0)^2 - 64(0) + 60

h = 60

The starting height is 60 feet.

-----

Now plug in h = 0 and solve for t.

h = -16t^2 - 64t + 60

0 = -16t^2 - 64t + 60

-16t^2 - 64t + 60 = 0

From here use the quadratic formula

[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-64)\pm\sqrt{(-64)^2-4(-16)(60)}}{2(-16)}\\\\t = \frac{64\pm\sqrt{7936}}{-32}\\\\t = \frac{64+\sqrt{7936}}{-32} \ \text{ or } \ t = \frac{64-\sqrt{7936}}{-32}\\\\t \approx -4.78388 \ \text{ or } \ t \approx 0.78388 \\\\[/tex]

We ignore the negative t value as a negative time doesn't make sense.

The only practical answer is roughly t = 0.78388 seconds.

Step-by-step explanation:

Just add 6 to 12 or 6 x 3

6th, 12th and 18th are the first 3 days that he will do both on the same day.

A number system is defined as a system of writing to express numbers

Given that Chris is going to play baseball every 2 days and he is going to play soccer every 3 days.

We need to find the three days that he will do  both on the same day

To find this we need to find the common multiples between 2 and 3.

The multiples of 2 are 4, 6, 8, 10,12, 14, 16, 18..

The multiples of 3 are 6, 9, 12, 15, 18...

Let us take first three common multiples of 2 and 3

Which are 6, 12 and 18

Hence, 6th, 12th and 18th are the first 3 days that he will do both on the same day.

Answer: x = 7

Step-by-step explanation: 16x = 4x + 84

15) The value of x would be 20.

16) The measure of angle BFH would be 100.

17) The value of x is, 7

Used the concept of angles in a parallel line which states that,

if a transversal intersects two parallel lines, the corresponding angles will be always equal.

Alternate angles are angles that occur on opposite sides of the transversal line and have the same size.

Given that,

In Figure 15, both angles are corresponding angles.

And, in Figure 17, both angles are Alternate angles.

Now, by definition of Alternate and Corresponding angles we get;

17) The angles DBF and angle EFB are congruent.

So, it can be equal.

16x = 4x+ 84

Subtract 4x on both sides,

16x - 4x = 84

12x = 84

Divide 12 on both sides,

x = 84/12

Therefore, the value of x is,

x = 7

15) The angles of CBD and BFH are conguent.

So, It can be equal.

5x = 3x + 40

Subtract 3x on both sides,

5x - 3x = 40

2x = 40

Divide 2 on both sides,

x = 40/2

x = 20

16) So, the measure of angle BFH is,

∠BFH = 3x + 40

= 3 × 20 + 40

= 60 + 40

= 100
