You will need 721 centimeters of paper. This is because you take 11 and multiply it by 11 because a cube is equal in the length and the height. To find the total area of wrapping paper for one side you have to find the area. 11x11=121. Then you have 6 sides of the cube so you multiply 121x6=721 inches of wrapping paper to wrap the cube

Least amount of wrapping paper you need to wrap the gift = 726 cm²

The total surface area of a cube is equal to six times the area of one side of the cube.

Given,

Side length of the cube = 11 cm

Area of one side of the cube = side²

Therefore, area of one side of the cube =  11² cm²

                                                                   = 121 cm²

Total surface area of a cube = 6 × side²

                                                = 6 × 121 cm²

                                                = 726 cm²

Hence, least amount of wrapping paper you need to wrap the gift is 729 cm².

Answer:

the explicit formula for the geometric sequence  2,6,18,54 is [tex]a_{n}=a_{1}.r^{n-1}[/tex]

2,6,18,54

Step-by-step explanation:

In the sequence given: 2,6,18,54

The common ration is 3 because

a₁ = 2

a₂= 2*3 =6

a₃ = (2*3)*3 = 2*3^2 = 18

a₄= (2*3*3)*3 =2*3^3 = 54

Here we see for a₂ 3 has power 1, for a₃ 3 has power 2 and so on.

So, the formula will be

[tex]a_{n}=a_{1}.r^{n-1}[/tex]

Here aₙ is the no of term.

a₁ is the first term of the sequence

and r is the common ratio among the sequence.

Answer:

The number of females is 288.

Step-by-step explanation:

Let the number of females be x.

5:4 = 360:x

We can write the equal ratios as a proportion.

5/4 = 360/x

Cross multiply:

5x = 360 * 4

5x = 1440

x = 288

Answer: The number of females is 288.

Answer:

288 females

Step-by-step explanation:

We can write a proportion to solve, putting males over females

males         5                  360

------------ = ------------ = -------------

females         4                  x

Using cross products

5x = 360*4

5x =1440

Divide by 5

5x/5 = 1440/5

x = 288

There are 288 females

Final answer is [tex]a_0=-9[/tex]

Step-by-step explanation:

Step-by-step explanation:

35× 34 = 1190...._ hope it help ....have a nice day

Answer:

1190

Step-by-step explanation:

Since the dot means "X" or multiply, we multiply 35 by 34.

So 35*34 = 1190.

A way to quickly multiply 35 snd 34, is to split 34 into 2*17 and multiply the 2 by 35 first to get 70*17. Since 17*7=119, we get 70*17 to be 1190.

Answer:

Expression: 2x-3

Martina's height if her little brother is 28 inches: 53 inches

Step-by-step explanation:

To write the expression, first read the problem. Martina is twice as tall as her little brother, minus 3. If x represents Martina's little brother's height, the equation will be 2x-3, since she's 3 inches shorter than twice the height of her little brother.

The question says that her little brother is 28 inches tall. Since x represents Martina's little brother's height, simply plug x into our expression.

2x-3

2(28)-3

56-3

53

Therefore, if Martina's little brother was 28 inches tall, Martina would be 53 inches tall. i hope this helps! :)

This answer involves the creation of a mathematical expression based on the given information and substituting the known value to find the unknown variable. The mathematical expression is 'Martina's Height = 2 * (Brother's height) - 3 inches.' When the brother's height is 28 inches, we get Martina's height as 53 inches.

The question relates to writing and solving expressions in Mathematics. To find how tall Martina is, we need to first write down an expression depicting the statement. According to the given statement, we can write:

Martina's Height = 2 * (Brother's height) - 3 inches

If her little brother is 28 inches tall, we substitute 28 into the expression:

Martina's Height = 2 * (28) - 3 inches

This implies:

Martina's Height = 56 - 3 inches = 53 inches

Therefore, Martina is 53 inches tall if her little brother is 28 inches tall.

Step-by-step explanation:

Eliminate the opposites

K-k+k3

= k-3

The given algebraic expression simplifies to k - 3. This means, for any value of 'k', the result would be 'k' minus 3.

The problem provided is k-k+k-3. In this case, 'k' is a variable, which is essentially an unknown number. When you subtract a variable (k) from itself, you get zero. Therefore, k - k equals zero. Adding k back again, we return to k itself. Hence, k - k + k - 3 simplifies to k - 3. That is, whatever value 'k' is, you have to subtract 3 from it to solve this equation.

Answer:

It's d. 0.

Step-by-step explanation:

The log (to any base) of 1 = 0, so log8 1 = 0, and the whole expression is equal to 0:

 0 * log3 27 = 0.

The expression log8 1 * log3 27 evaluates to 0, so the equivalent expression from the options is d - 0.

The expressions we need to evaluate are log8 1 * log3 27. The log of 1, no matter what the base, is always 0. This is because any number raised to the power of 0 is 1. So, log8 1 is equal to 0. Now, evaluate log3 27. The log base 3 of 27 is 3 because 3 cubed (or 3 to the power of 3) is 27. So, log3 27 equals 3. Thus, log8 1 * log3 27 = 0 * 3 = 0. Comparing with the given options, we find that the only equivalent expression is option d - 0.

Answer:

[tex]|A'B'|=\sqrt{5}[/tex]

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

[tex]|AB|=\sqrt{(4-0)^2+(2-4)^2}[/tex]

[tex]|AB|=\sqrt{(4)^2+(-2)^2}[/tex]

[tex]|AB|=\sqrt{16+4}[/tex]

[tex]|AB|=\sqrt{20}[/tex]

[tex]|AB|=2\sqrt{5}[/tex]

Since quadrilateral ABCD was enlarged with  a scale factor of [tex]\frac{1}{2}[/tex].

The length of A'B' is

[tex]\frac{1}{2}|AB|[/tex]

[tex]=\frac{1}{2}\times2\sqrt{5}[/tex]

[tex]\therefore |A'B'|=\sqrt{5}[/tex]

The quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So, after the dilation the length of A'B' is [tex]\sqrt{5}[/tex] and this can be determined by using the formula of length between two points.

Given :

Given that the quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So the points of the quadrilateral ABCD becomes:

[tex]\rm A(0,4) \to A'(0\times \dfrac{1}{2},4\times \dfrac{1}{2}) = A'(0,2)[/tex]

[tex]\rm B(4,2) \to B'(4\times \dfrac{1}{2},2\times \dfrac{1}{2}) = B'(2,1)[/tex]

[tex]\rm C(4,-4) \to C'(4\times \dfrac{1}{2},-4\times \dfrac{1}{2}) = C'(2,-2)[/tex]

[tex]\rm D(-2,-2) \to D'(-2\times \dfrac{1}{2},-2\times \dfrac{1}{2}) = D'(-1,-1)[/tex]

Now, the length of A'B' is given by:

[tex]\rm AB=\sqrt{(4-0)^2+(2-4)^2}[/tex]

[tex]\rm AB=\sqrt{4^2+(-2)^2}[/tex]

[tex]\rm AB=\sqrt{20}[/tex]

[tex]\rm AB = 2\sqrt{5}[/tex]

Sin C = 12/13

I would assume that they want a cosine value that would give the same answer. sin(30°) is equal to 1/2

Therefore cos(×) = 1/2

x = arccos(1/2)

x=60

cos(60°)

Answer:

cos60°

Step-by-step explanation:

Using the cofunction identity

sinx° = cos(90 - x)°

sin30° = cos(90 - 30)° = cos60°

Let the number be x.

4x - 8 =12

4x =12 +8 ( you bring the eight over to the 12, it becomes positive )

4x = 20

x = 20÷4

x = 5

The problem is a basic algebra equation. It translates to 4x - 8 = 12, which can be solved by adding 8 to both sides and then dividing by 4 to get x=5. The answer is 5.

The subject of this question is Mathematics, specifically algebra. To solve this equation, start by translating the problem into a mathematical expression. This can be done as follows: 4 times a number is represented as 4x, then decreased by eight is -8 and the equation equals twelve (12).

Therefore, the equation is 4x - 8 = 12. To solve for x, you can start by adding 8 to both sides of the equation obtaining 4x = 20. Lastly, divide both sides by 4 to find x, which gives x = 5.

Therefore, the number that meets the condition '4 times a number, decreased by 8 equals 12' is 5.

Final answer:

Miss Balcon would work 150 hours in 4 weeks as a secretary at a Christian school.

Explanation:

In order to find out how many hours Miss Balcon would work in 4 weeks, we need to first calculate the number of hours she works in a week. She works 7 1/2 hours each day, and since there are 5 days in a week, she works a total of 7 1/2 x 5 = 37 1/2 hours in a week.

Now, to find out how many hours she would work in 4 weeks, we can multiply the number of hours she works in a week by 4. So, 37 1/2 x 4 = 150 hours.

Therefore, Miss Balcon would work 150 hours in 4 weeks.
