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.

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]

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.

1/2x - 7.5Step-by-step explanation:The image below shows proof that the equation y = 1/2x - 7.5

Step-by-step explanation:

The equation of the line contains the point ( 3 , -6) graph is shown below.

Since the point (3, -6) lies on the line, we can use the point-slope form of linear equations to find the equation of the line, which is:

[tex]y - y_1 = m(x - x_1)[/tex]

where [tex](x_1, y_1)[/tex]  is the point on the line and m is the slope of the line.

Substituting in (3, -6) and m = 1/2, we get:

y - (-6) = 1/2(x - 3)

y + 6 = 1/2x - 3/2

y = 1/2x - 3/2 - 6

y = 1/2x - 9/2

To graph the line, we can start by plotting the point (3, -6). Then, we can use the slope to find another point on the line.

Since the slope is 1/2, it means that for every 1 unit we move up, we must also move 2 units to the right.

Therefore, we can move 2 units to the right and 1 unit up from (3, -6) to find the point (5, -5). We can then plot this point and connect the two points with a line.

Here is a graph of the line that contains the point (3, -6) and has a slope of 1/2:

The graph shows that the line passes through the point (3, -6) and has a positive slope.

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

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

Step-by-step explanation:

The discriminant of the quadratic function f(x) = -4x^2 + 10x - 8 is -28. Since the discriminant is negative, there are no distinct real number zeros for this function.

Your question involves finding the discriminant of the quadratic function f(x) = -4x2 + 10x - 8 and determining how many distinct real number zeros it has. The discriminant of a quadratic equation in the form ax2 + bx + c is given by b2 - 4ac. In your case, a = -4, b = 10, and c = -8. Let's calculate the discriminant:

b2 - 4ac = (10)2 - 4(-4)(-8)

b2 - 4ac = 100 - 128

b2 - 4ac = -28

Since the discriminant is negative (b2 - 4ac < 0), the quadratic function f(x) has no real number of zeros. Therefore, the graph of the function does not cross the x-axis, and there are no distinct real roots.

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.
