The expressions for the volume of the composite pyramid figure is given by A = One-third(7)(12)(10) - One-thirdπ(32)(10) = 280 - 30π

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

A pyramid with a square base with dimensions 12 by 7 is shown. A cone is cut out of the center of the pyramid.

The cone has a height of 10 and a diameter of 6.

The correct expression to represent the volume of the composite figure (the shaded figure) is:

One-third(7)(12)(10) - One-thirdπ(3)²(10) = 280 - 30π

So the expressions that apply are:

One-third(7)(12)(10) - One-thirdπ(32)(10) = 280 - 30π

Hence , the volume of pyramid is 280 - 30π

Answer:

13.73

Step-by-step explanation:

Answer: 13.7345175425633 square feet

The rounding instructions are cut off, so it's not clear how you want to round this.

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

Explanation:

The area of the square is 8*8 = 64 square feet.

The two unshaded semicircles combine to form a full circle of radius 4 ft. This circle has an area of A = pi*r^2 = pi*4^2 = 16pi square feet.

The shaded area is the result of taking the circle area away from the larger square area

shaded area = (area of large square) - (area of two semicircles)

shaded area = (area of large square) - (area of circle with radius 4)

shaded area = 64 - 16pi = exact value

shaded area = 13.7345175425633 = approximate value

Answer:D. 0.039

Step-by-step explanation:

The probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have the total number of male students = 70+50+60 = 180

So, the total number of outcomes = 180

Total number of male students who take humanities class = 70

Now, the probability = 70/180 = 0.388 ≈ 0.389

Thus, the probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.

Joshua's 15 ft ladder, if leaned against the wall to reach a height of 14.8 ft, would be at an unsafe angle less than 70° and thus, is not safe to use in this manner.

The student has asked whether Joshua's ladder, which is 15 feet long and is supposed to lean against a wall with the top at 14.8 feet above the ground, will be safe with an angle no greater than 70°. To determine this, we can use the trigonometric function cosine, which relates the adjacent side (the height at which the top of the ladder reaches the wall) to the hypotenuse (the length of the ladder) in a right-angled triangle. The cosine of the maximum safe angle (70°) should therefore be equal to or greater than the ratio of the height of the ladder against the wall (14.8 feet) to the length of the ladder (15 feet).

We calculate the cosine of 70°: cos(70°) ≈ 0.342. Then we calculate the ratio 14.8/15 which equals 0.9867. Since 0.9867 is much greater than 0.342, it means the ladder will form an angle that is less than 70°, which is not within the safe range as per Joshua's requirement.

Therefore, it is not safe for Joshua to lean the ladder in this manner because the angle formed will be steeper than the maximum safe angle of 70°, which may result in the ladder slipping.

Answer:

2x + 2y = 32

Step-by-step explanation:

2 sides of each rectangle are always equal to each other, and there's 2 pairs of that, top&bottom and side&side

The perimeter is all the sides added together, so it's x + x +y +y, which can be written as 2x + 2y

The relationship between the length (x) and width (y) of a rectangle with a perimeter of 32 can be represented by the equation 2*(x+y)=32, derived from the formula for the perimeter of a rectangle.

The subject of this question is mathematics, specifically relating to geometry and algebra. To express the relationship between the length, x, and width, y, of a rectangle with a perimeter of 32, you can form an equation based on the formula for the perimeter of a rectangle.

The formula for the perimeter of a rectangle is 2*(length+width). In this case, the length is x and the width is y, and we know that the total perimeter is 32. This can be expressed in the following equation: 2*(x+y) = 32.

Answer:

The budget breakdown is as follows;

Savings = $354.00

Clothing = $88.50

Entertainment = $88.50

Charitable giving = $44.00

Amount left = $0.00

Step-by-step explanation:

In the budgeting process, needs and the recurring expenditures are first addressed followed by savings which consists of emergency funds that can be used on unexpected expenses and reduces the tendency for borrowing.

Therefore, the appropriate amount for savings in a budget is found from the 50-20-30 rule.

That is the after tax income is weighted to 100 from which;

50% is expended on needs and recurring expenditures

20% of the after tax income should be kept as savings and

30% can be spent on wants

Based on the above rule, with a take home pay of $1,770 we have;

Amount meant for savings = 20% of $1,770 = $354.00

Since $354.00 is to be kept as savings we have;

Amount on Clothing + Entertainment + Charitable = $575 - $374 = $221

The amount on clothing should be 5% of the monthly income, which gives;

5% of $1,770 = 0.05× $1,770 = $88.5

Therefore amount on entertainment which should also be 5% =$88.5

Hence the amount for charitable giving = $221 - $88.5 - $88.5 = $44.00

Hence the budget breakdown should be;

Savings = $354.00

Clothing = $88.50

Entertainment = $88.50

Charitable giving = $44.00

Amount left = $0.00.

Budget represents financial plan over a period of time.

The money would be allocated as follows:

The total home pay is given as:

[tex]Total = \$1770[/tex]

In budget, 20% are always allocated to savings.

So, we have:

[tex]Savings = 20\% \times Total[/tex]

[tex]Savings = 20\% \times \$1770[/tex]

[tex]Savings = \$354[/tex]

The amount to spend is given as:

[tex]Spend = \$575[/tex]

The amount left, after savings is:

[tex]Amount = Spend - Savings[/tex]

[tex]Amount = \$575 - \$354[/tex]

[tex]Amount = \$221[/tex]

The $221 would be spent on entertainments, clothing and charitable givings.

In budgets, 5% of total home pay is always allocated for entertainments and for clothing.

So, we have:

[tex]Clothing = 5\% \times Total[/tex]

[tex]Clothing = 5\% \times \$1770[/tex]

[tex]Clothing = \$88.5[/tex]

Also

[tex]Entertainment = Clothing = \$88.5[/tex]

The amount on charitable giving is:

[tex]Giving = Amount\ Left - Entertainment - Clothing[/tex]

[tex]Giving = \$221 - \$88.5 - \$88.5[/tex]

[tex]Giving = \$44[/tex]

Hence, the money would be allocated as follows:

[tex]Savings = \$354[/tex]

[tex]Clothing = \$88.5[/tex]

[tex]Entertainment = \$88.5[/tex]

[tex]Charitable\ Giving = \$44[/tex]

Answer:

50 miles

Step-by-step explanation:

60 divided by 30 = 5

5 miles = 10% of the trip

40% of the trip left to go

40% = 20 miles (5 x 4)

30 + 20 = 50

hope this helps!

To find the length of the whole trip, set up a proportion using the given information and solve for the missing variable. The whole trip is approximately 50 miles long.

To find the length of the whole trip, we can set up a proportion using the information given. We know that 60% of the trip is equivalent to 30 miles. We can set up the proportion:

60% / 100% = 30 miles / x

By cross-multiplying, we get:

x = (30 miles * 100%) / 60%

Calculating this, we find that the whole trip is approximately 50 miles long.

Step-by-step explanation:

The days will the chocolate last is A) More than 12 days . Therefore A) More than 12 days is correct .

One chocolate bar lasts for 12 days because 1 / (1/12) = 12

Two chocolate bars last for 24 days because 12 * 2 = 24

So, even if Luna has one s'more a day, the chocolate will last for more than 12 days.

The other options are not as likely:

Option (B) is less likely because two chocolate bars would still last for more than a day, even if she had one s'more a day.

Option (C) is possible, but it's less likely than option (A) because two chocolate bars would provide more than 12 s'mores worth of chocolate.

Therefore, the answer is A) More than 12 days.

Question

Luna packed two chocolate bars for the trip. One s'more uses 1/12 of a bar. If she has one s'more a day, about how many days will the chocolate last?

A) More than 12 days

B) Less than 1 day

C) Between 1 and 12 days

The converse of a theorem is a logical statement where the elements of the theorem's statement are switched. If you have a theorem that states "If A, then B," the converse of that theorem would be "If B, then A." This essentially transposes the hypothesis and the conclusion. In the context of the multiple-choice options provided, the correct answer is D.

A statement formed by transposing what is to be proved by a theorem and what is given. It's important to note that even though a theorem is proven true, its converse is not necessarily true and must be proven separately if it is to be accepted as true.

Answer:

a. 60

b. 25

Step-by-step explanation:

Given that the stained glass window has an area of 900 square inches and this is made of smaller rectangular stained glass pieces, the number of smaller rectangular stained glass pieces used will be equal to the total area (900 square inches) to the area of the smaller rectangular piece.

The area A of the rectangular piece of length l and width w may be stated  as

A = l * w

Hence given  that

- One window design is made of rectangular stained glass pieces that are 5 inches by 3 inches, number of stained glass pieces are used in the window

= 900/(3 * 5)

= 60

- Another window design is made of square stained glass pieces that are 6 inches by 6 inches, number of stained glass pieces are used in the window

= 900/(6 * 6)

= 25

Answer:

a. 60 pieces

b. 25 pieces

Step-by-step explanation:

Hi, to answer this question we have to calculate the area of each rectangular stained glass.

Area = width x length

a.

5 x 3 = 15 square inches

Now we have to divide the area of the window by the area of each stained glass.

900/ 15 = 60 pieces

Same process for b

b.

6x6 = 36  square inches

900/36= 25  pieces
