Step-by-step explanation:

32/400

The shaded portion of the figure in square feet is 78.5 ft².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses.

As, its diagonal is equal to the diameter of the circle which is 10 feet.

Let the width of the rectangle be x, then its length is 10-x.

Using the Pythagorean theorem, we can write:

x² + (10-x)² = 10²

2x² - 20x + 100 = 100

2x² - 20x = 0

2x(x-10) = 0

x =10, which means the rectangle is actually a square.

Therefore, its area is 10² = 100 square feet.

Now, the area of the shaded portion is

= area of the circle - area of the square.

Then, Radius is 5 feet.

So, the area of the circle

= π(5²)

= 25π square feet.

Therefore, the area of the shaded portion is:

= 25π - 100

≈ 78.5 square feet.

Answer: 15

Step-by-step explanation:

Write 12% as a fraction: 12/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have: 12/100 of 125.

12/100 × 125

If you are using a calculator, enter 12÷100×125 which will give you 15 as the answer.

Answer:

The volume of a pyramid is:

v = (1/3)Bh, where B is the area of the base and h is the height.

So, V = (1/3)(225)(20) = 1,500

Conclusion: The volume is 1,500 cubic inches.

Answer:

The value of C in the table is 0. Total number of cake lovers = Total - (number of students who chose pie) = 138 - (36 + 42 + 60) = 138 - 138 = 0

Step-by-step explanation:

The value of C in the given table is 10. Therefore, option B is the correct answer.

The property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.

From the given table,

42/7 = 60/C (Using proportionality)

6=60/C

C=10

Therefore, option B is the correct answer.

Answer:

C

Step-by-step explanation:

It isn't B because the point does not start at 600 and it is not A because it shows the entire decrease of the mass in one millennium. The correct answer is c.

Answer:

Step-by-step explanation:

The equation for the area of a circle is A=\(\pi\)\(r^{2}\).

A=area

r=radius

We were given the diameter of the circle not the radius, so we need to solve for the radius.

Radius=(1/2)Diameter So,

(1/2)6=3mm

Now we can solve for the area.

3^2(3.1415926)=28.2743mm

Now round to two decimal places.

28.27mm

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Total number of cards = 48

Red cards/black cards = 1/1

(so, 24 each of read and black cards)

8 red cards are removed.

Now, there will be (24-8) number of cards left in the pack which equals to 16 cards.

So, now the number of red cards in the pack= 16

Number of black cards = 24

Ratio of red card/ black card

\( = \frac{16}{24} \)

\( = \frac{2}{3} \)

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Answer:

294 cm²

Step-by-step explanation:

Surface area of top opened rectangular prism:

             l = 6 cm ;  w = 6 cm ;  h = 7 cm

     \(\sf \boxed{ \text{ surface area = 2h(l+w) + lw}}\)

                            = 2*7 *(6 + 6 ) + 6*6

                            = 2*7*12 + 36

                            = 168 + 36

                            = 204 cm²

Surface area of right triangular prism:

           In, right triangular prism, the base rectangle is not included.

   Surface area = bh + (S1 + S2)*L

         b is the base of the triangle. b= 6 cm

         h is the altitude of the triangle. h = 4cm

         S1 and S2 are the edges of the triangle.

        S1 = 4 cm ;  S2 = 7 cm

        L is the length of the prism. L = 6 cm

          Surface area = 6*4 + (4 + 7)*6

                                 = 24 + 11 *6

                                 = 24 + 66

                                 = 90 cm²

Surface area of the composite figure = 204 + 90

                                                              = 294 cm²
