a box is 12 centimeters wide, 12 centimeters long, and 15 centimeters tall. what is the total surface area of 4 such boxes

Answer:

4 5/8 the answer you have is correct :)

Step-by-step explanation:

First, you want to make the mixed fraction into an improper fraction.

 7 x 4 + 3 = 31 (31/4)

3 x 8 + 1 = 25 (25/8)

Now you want them both to have a common denominator.

31/4 x 2/2 = 62/8

Now you are ready to subtract!

62/8 - 25/8 = 37/8

Finally, convert 37/8 to a proper fraction.

37/8 = 4 5/8

A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of 11/2 inch. So, the correct answer is (D).

To determine the correct answer, we need to compare the diameters of the two pipes and understand the relationship between pipe diameter and threads per inch.

The number of threads per inch generally decreases as the pipe diameter increases. This means that a larger pipe diameter will have fewer threads per inch compared to a smaller pipe diameter.

Given that the first pipe has a diameter of 1 1/4 inches, we need to find the pipe diameter from the options that is larger than 1 1/4 inches.

The option that meets this requirement is D. 11/2. This represents a pipe diameter of 1 1/2 inches. Therefore, a pipe with a diameter of 1 1/2 inches should have fewer threads per inch than a pipe with a diameter of 1 1/4 inches. Therefore, the correct answer is D. 11/2.

The actual average score on the vocabulary test is 91.8.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Here, Mr. Johnson predicted the average score on the vocabulary test he gave would be 85 points and his prediction was 8% lower than the actual average score.

The actual score will be:

= 85 + (8% × 85)

= 85 + 6.8

The area for the given quadrilateral will be 5400m^2, Perimeter=300m and no. of rabbits that van fit are 270.

what are quadrilaterals?

A quadrilateral is a polygon with four sides, four vertices, and four angles.

It is formed by joining four non-collinear points. The sum of the interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ‘Latus’ means ‘sides’. Not all the four sides of a quadrilateral need to be equal in length. Hence, we can have different types of quadrilaterals based on sides and angles.

Five special quadrilaterals are shown below in the image, along with their definitions and pictures, and points for them to get proven.

Now

as given quadrilateral is rectangular in shape because opposite sides are equal and parallel.

and Length = 90m and breadth=60m

Therefore,

Area=L*B =90*60=5400m^2

Perimeter=2(L+B)=2*150=300m

Answer:

m<GFC = 69 degrees

Step-by-step explanation:

The angle with 37 degrees is congruent with the angle on the left of 74 because of the Alternate Interior Angles Postulate

The last angle in the triangle that you don't know the degrees of is on the right of angle 74 because of the Alternate Interior Angles Postulate

So 37+74+ (the degree we don't know of the triangle) = 180 because of linear triples

180 - (37+74) = 69

So the angle on the right of angle 74 = 69

So m<GFC = 69 degrees

Answer:

Its 69

Step-by-step explanation:

the three measures will add up to 180 so all you hace to do is add the angles given and subtract that from 180 to find x

Answer:

110

Step-by-step explanation:

nth term = 3n + 2

3 (36) + 2

108 + 2 = 110

Answer:

The 36th term in the sequence is 104.

Here's how to find it:

- Start with the first number in the sequence: 5.

- Add the common difference, which is 3, to get the second number in the sequence: 8.

- Add the common difference to the second number to get the third number: 11.

- Continue adding the common difference to each subsequent number to find the next term in the sequence.

- The 36th term is three less than 37 times the common difference added to the first term.

- Using that formula, we can calculate the 36th term as: 5 + (36 - 1) * 3 = 5 + 105 = 110.

- Therefore, the 36th term in the sequence is 104.

The expression in the options which is equivalent to the given expression is D. (22x + 48) / (x² - 36).

Given expression is,

[15 / (x - 6)] + [7 / (x + 6)]

Cross multiplying the two fractional expressions,

= [15 (x + 6) + 7 (x - 6)] / [(x - 6) (x + 6)]

= [15x + 90 + 7x - 42] / [x² - 6²]

= (22x + 48) / (x² - 36)

Hence the equivalent expression is D.

Let x represent how many days the client paid for pet sitting.

$15 per day plus a $20 fixed service fee equals the total cost of pet sitting.

Answer:

(1) 13.0 years

(2) \(y^{3} =\) {-1728, 1728}

Step-by-step explanation:

(1)

Compound annually:

\(Pe^{rt}\) = A

(47000)\(e^{(0.04)(t)}\) = 79200

\(e^{(0.04)(t)}\) = \(\frac{79200}{47000}\)

ln(\(e^{(0.04)(t)}\)) = ln(\(\frac{79200}{47000}\))

ln and e cancel out.

(0.04)(t) = ln(\(\frac{79200}{47000}\))

t = \(\frac{ln(\frac{79200}{47000})}{0.04}\)

t = 13.0 years

(2)

\(x^{2} +y^{2} = 153\\y = -4x\)

Substitute y with -4x.

\(x^{2} + (-4x)^{2} = 153\)

Solve for x.

x = {-3, 3}

Plug in x values into any equation to find y.

y = -4(-3) and y = -4(3)

y = {-12, 12}

\(y^{3}\) = \(-12^{3}\) = -1728

\(y^{3}\) = \(12^{3}\) = 1728
