Answer:

D

Step-by-step explanation:

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 12 when x = 15

12 = 15k ( divide both sides by 15 )

0.8 = k

y = 0.8x ← equation of proportion

When y = 40 , then

40 = 0.8x ( divide both sides by 0.8 )

Given:

Volume of quarter sphere = 1,944π cm³

Required:

Surface area

Solution:

✔️First, find the radius (r).

Volume of the quarter sphere = ¼(⁴/3πr³)

Thus:

1944π = ¼(⁴/3×π×r³)

1944π = ⅓×π×r³

Multiply both sides by 3

1944π×3 = 1×π×r³

5,832π = πr³

Divide both sides by π

5,832π/π = r³

5,832 = r³

Find the cube root of both sides

r = 18

Radius = 18 cm

✔️Find the surface area of the quarter sphere

Surface area of quarter sphere = ¼ of 4πr² + 2(½ of πr²)

Radius (r) = 18 cm

Plug in the values

Surface area of quarter sphere = ¼×4×π×18² + 2(½×π×18²)

= π×18² + π×18²

= 2,035.75204 ≈ 2,040 cm² (to 3 SF)

The line y = mx + 4 has a slope of 2 and it is y = 2x + 4.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines parallel to each other have the same slope.

We also know, slope(m) = (y₂ - y₁)/(x₂ - x₁).

Slope(m) = (6 + 2)/(5 - 1).

slope(m) = 8/4.

slope(m) = 2.

So, The line y = mx + 4 is, y = 2x + 4.

Simone buy 5 books and 17 vinyl records.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Simone bought a total of 22 used books and vinyl records during a yard sale for a total of $78.50.

And, Books cost $3.00 each and the vinyl records cost $5.50 each.

Let number of books = x

And, Number of vinyl records = y

Hence, We cam formulate;

⇒ x + y = 22  .. (i)

⇒ 3x + 5.50y = 78.50  .. (ii)

Substitute the value of x from (i) in (ii), we get;

⇒ 3x + 5.50y = 78.50

⇒ 3(y - 22) + 5.50y = 78.50

⇒ 3y - 66 + 5.50y = 78.50

⇒ 8.50y = 78.50 + 66

⇒ 8.50y = 144.5

⇒ y = 17

From (i);

⇒ x + y = 22  

⇒ x + 17 = 22  

⇒ x = 5

Thus, Simone buy 5 books and 17 vinyl records.

Answer:

  24.98 units

Step-by-step explanation:

You want the perimeter of triangle ABC with vertices A(-5, 4), B(1, -2), and C(3,6).

The distance between two vertices can be found using the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The  distance between A and B is ...

  d = √((1 -(-5))² +(-2 -4)²) = √(6² +(-6)²) = 6√2 ≈ 8.485

The attached spreadsheet performs the same calculation on all the pairs of points. (The distance from each point to the one below it is listed.)

The perimeter of the triangle is the sum of the segment lengths. That is also shown in the spreadsheet.

  P = AB +BC +CA

  P = 8.485 +8.246 +8.246 ≈ 24.98

The perimeter of triangle ABC is about 24.98 units.

The area of triangle is 7.4833 ft².

Heron's formula used to calculate the areas of various triangles, including quadrilaterals and the equilateral, isosceles, and scalene triangles.

The Heron's Formula states that the area of a triangle is equal to √s(s-a)(s-b)(s-c), where s is the triangle's semi-perimeter and a, b, and c are its three side lengths.

s= (a+ b+ c)/2

Given:

sides: 3 feet, 5 feet and 6 feet.

semi- perimeter, s= 3+5+6/2 = 7

Now, Using Heron's Formula

= √s(s-a)(s-b)(s-c)

=√7(7-3)(7-5)(7-6)

=√7 x 4 x 2 x 1

=√56

= 7.4833 ft²

The probability of it raining 5 days out of the week, given an average chance of rain of 36% each day, is approximately 0.036 or 3.6%.

To find the probability of it raining 5 days out of the week when the chance of rain each day is 36%, we can use the binomial probability formula.

The binomial probability formula is given by:

P(X = k) = (nCk) * p^k * (1-p)^(n-k)

Where:

P(X = k) is the probability of getting exactly k successes

n is the number of trials

k is the number of desired successes

p is the probability of success in a single trial

(1-p) is the probability of failure in a single trial

In this case, we have:

n = 5 (number of days in the week)

k = 5 (desired number of rainy days)

p = 0.36 (probability of rain each day)

Using the formula, we can calculate the probability:

P(X = 5) = (5C5) * (0.36)^5 * (1-0.36)^(5-5)

Simplifying the equation:

P(X = 5) = 1 * 0.36^5 * 0.64^0

P(X = 5) ≈ 0.036

Answer as an improper fraction = 30/8 miles

Answer as a mixed number = 3 & 3/4 miles

Answer in decimal form = 3.75 miles

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

How to get that answer:

Let's start with what we're given

Assuming this site is a rectangle, then we can say:

area = length*width

5/8 = (1/6)*w

(5/8)*(6/1) = w

(5*6)/(8*1) = w

30/8 = w

w = 30/8

The answer as an improper fraction is 30/8 miles.

If you want to convert that to a mixed number, then,

30/8 = (24+6)/8

30/8 = 24/8 + 6/8

30/8 = 3 + 3/4

30/8 = 3 & 3/4

The answer as a mixed number is 3 & 3/4 miles

Meaning the width is a full 3 miles wide, plus an additional 3/4 of a mile as well.

In decimal form, the answer is 3.75 miles

The question is asking for the value of z that satisfies the probability that a standard normal variable z is less than z to be 0.9525. In other words, we want to find the z-score that corresponds to the 95.25th percentile of the standard normal distribution. Option (b) is the closest to the correct answer (-1.67). However, this could be due to rounding errors or differences in the table used. Therefore, the correct answer is (f) None of the above.

To solve this problem, we can use a standard normal distribution table or a calculator with a normal distribution function. Using a standard normal distribution table, we can look up the closest value to 0.9525 in the body of the table, which is 0.9515. The corresponding z-score is 1.65.

However, since the table only gives us values for the area to the left of a positive z-score, we need to subtract 1.65 from 0 (the mean of the standard normal distribution) to get the z-score that corresponds to the 95.25th percentile on the left tail. Therefore, the answer is -1.65. So none of above is correct.

Given that $OF = 9$ and $OF' = 12,$ where $F$ and $F'$ are the foci of the ellipse, we can determine the lengths of the major and minor axes.

In an ellipse, the sum of the distances from any point on the ellipse to the two foci is constant. This property is expressed by the equation:

$$PF + PF' = 2a,$$

where $P$ is any point on the ellipse and $a$ is the semi-major axis. In our case, $P = O,$ and since $OF = 9$ and $OF' = 12,$ we have:

$$9 + 12 = 2a,$$

$$21 = 2a.$$

Therefore, the semi-major axis $a$ is equal to $\frac{21}{2} = 10.5.$

The distance between the center of the ellipse and each focus is given by $c,$ where $c$ is related to $a$ and the semi-minor axis $b$ by the equation:

$$c = \sqrt{a^2 - b^2}.$$

We can solve for $b$ using the distance to one focus:

$$c = \sqrt{a^2 - b^2},$$

$$c^2 = a^2 - b^2,$$

$$b^2 = a^2 - c^2,$$

$$b = \sqrt{a^2 - c^2}.$$

Substituting the known values:

$$b = \sqrt{10.5^2 - 9^2},$$

$$b = \sqrt{110.25 - 81},$$

$$b = \sqrt{29.25},$$

$$b \approx 5.408.$$

Therefore, the semi-minor axis $b$ is approximately $5.408.$

Finally, we can determine the lengths of the major and minor axes:

The major axis $\overline{AB}$ is twice the semi-major axis, so $\overline{AB} = 2a = 2(10.5) = 21.$

The minor axis $\overline{CD}$ is twice the semi-minor axis, so $\overline{CD} = 2b = 2(5.408) \approx 10.816.$

Therefore, the major axis $\overline{AB}$ is $21$ units long, and the minor axis $\overline{CD}$ is approximately $10.816$ units long.
