THE AREA OF A CIRCLE = πr^2

Here π = 3.142

r = 7.5

now A = πr^2

A = 3.142× 7.5×7.5

A = 176.7375cm^2

Answer:

The area of shaded = 13.09 cm^2

Step-by-step explanation:

360 /6 = 60

So the shaded area is 1/6 of the circle

Area of circle = pie r^2

So area of shaded = 1/6(pie r^2)

= 1/6 * 3.142 * 5^2

= 13.09 cm^2

Answer:

18 stickers.

Step-by-step explanation:

Cindy buys 18 more stickers in the start. This results in 13+18= 31 stickers. She then gets five for her birthday. 31+5=36 so she now has 36 stickers but she then gives eight away which means she has 36-8=28 stickers. She uses ten stickers to decorate so Cindy has 28-10=18 stickers left

The value of b is -6.

To find the value of b, we need to solve the quadratic equation b2 + 2b - 24 = 0.

Since b < 0, we can eliminate the positive solution.

We can factor the equation by finding two numbers whose product is -24 and sum is 2.

The numbers are -4 and 6.

So, the factored form of the equation is (b - 4)(b + 6) = 0.

Setting each factor equal to zero, we find that b = -6 or b = 4.

Since b < 0, the value of b is -6.

Final answer:

Using the quadratic formula, we find that b = -6 (option A), considering the requirement that b < 0 for the equation b² + 2b - 24 = 0.

Explanation:

To find the value of b given the quadratic equation b² + 2b − 24 = 0 and knowing that b is less than zero, we can use the quadratic formula:

The quadratic formula is −b ± √(b² − 4ac /2a), where a, b, and c are coefficients from the quadratic equation in the form ax2 + bx + c = 0.

In this case, a = 1, b = 2, and c = −24. Applying these values to the quadratic formula, we have:

−(2) ± √((2)² − 4(1)(−24) /2(1))

The discriminant part of the formula, b² − 4ac, equals (2)² − 4(1)(−24) = 4 + 96 = 100. Therefore, the square root of the discriminant is 10.

Simplifying further, we have:

(−2 ± 10) / 2 = −6 or +8

Since b < 0, we disregard the positive solution and consider b = −6, which is option A.

Answer:

See picture attached.

Step-by-step explanation:

To find the solution, graph each equation using the y = mx + b form.

Start by converting to this form.

x + 2y < 4 becomes y < -1/2x +2

3x - y > 2 becomes y < 3x - 2

Then mark each y-intercept. These points are (0,2) and (0,-2).

Using the slope mark the next points at (-1,4) and (1, -1) respectively.

Connect using dash lines since this is not equal to in either inequality.

Test a point no on either line like (-1,-1).

If the inequality holds true, shade the area.

Where the areas overlap is the solution. See picture.

Inequalities are used to represent unequal expressions.

The solution to the inequality is [tex]x \le \frac 87[/tex] and [tex]y < \frac{10}7[/tex]

The inequalities are given as:

[tex]x + 2y \le 4[/tex]

[tex]3x - y > 2[/tex]

Express both inequalities as equations'

[tex]x + 2y = 4[/tex]

[tex]3x -y = 2[/tex]

Make y the subject in [tex]3x -y = 2[/tex]

[tex]y = 3x - 2[/tex]

Substitute [tex]y = 3x - 2[/tex] in [tex]x + 2y \le 4[/tex]

[tex]x + 2(3x - 2) \le 4[/tex]

Open brackets

[tex]x + 6x - 4 \le 4[/tex]

[tex]7x - 4 \le 4[/tex]

Collect like terms

[tex]7x \le 4+4[/tex]

[tex]7x \le 8[/tex]

Divide both sides by 7

[tex]x \le \frac 87[/tex]

Substitute 8/7 for x in [tex]3x - y > 2[/tex]

[tex]3 \times \frac 87 - y > 2[/tex]

[tex]\frac{24}7 - y > 2[/tex]

Collect like terms

[tex]- y > 2 -\frac{24}7[/tex]

Take LCM

[tex]- y > \frac{14 -24}7[/tex]

[tex]- y > \frac{-10}7[/tex]

Divide both sides by -1

[tex]y < \frac{10}7[/tex]

Answer:

The correct option is B.

Step-by-step explanation:

If polar coordinates of point P are

[tex]P=(r,\theta)[/tex]

Where, r is real number and θ is in radian, then all polar coordinates of point P are defined as

[tex]P=(r,\theta+2n\pi)[/tex]

[tex]P=(-r,\theta+(2n+1)\pi)[/tex]

The given coordinates are [tex]P(5,-\frac{\pi}{6})[/tex]. So, all polar coordinates of point P are

[tex]P=(5,-\frac{\pi}{6}+2n\pi)[/tex]

[tex]P=(-5,-\frac{\pi}{6}+(2n+1)\pi)[/tex]

Therefore correct option is B.

Answer:

$3.79 for an 8 foot board

Step-by-step explanation:

The way to find the answer is calculating the price per foot.

Part 1

$3.79 for an 8 foot board.

one foot would cost:

$3.79 ÷ 8  =  0.47375

Part 2

$6.18 for a 12 foot board?

Price of one foot would be:

$6.18 ÷ 12 = 0.515

$0.47375 is less than $0.515. So, the cheaper treated lumber is the one costing $3.79 for an 8 foot board.

Answer:

The answer is 2.333 yards

Step-by-step explanation:

In every one yard there's thirty-six inches.

84/36= 2.333

Hope this helps :)

To convert 84 inches to yards, first convert inches to feet by dividing by 12, resulting in 7 feet. Then, convert feet to yards by dividing by 3, resulting in approximately 2.33 yards.

To convert 84 inches to yards, we need to use the relationships between inches, feet, and yards.

Start by converting inches to feet, and then convert feet to yards.

1. Convert inches to feet:

There are 12 inches in a foot, so divide the number of inches by 12.
84 ÷ 12

= 7 feet

2. Convert feet to yards:

There are 3 feet in a yard, so divide the number of feet by 3.
7 ÷ 3

= 2.33 yards

Thus, 84 inches is equal to approximately 2.33 yards.

Simplifying

4x + -3y = 12

Solving

4x + -3y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

4x + -3y + 3y = 12 + 3y

Combine like terms: -3y + 3y = 0

4x + 0 = 12 + 3y

4x = 12 + 3y

Divide each side by '4'.

x = 3 + 0.75y

Simplifying

x = 3 + 0.75y

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

The formula of a slope:

We have the points (a, b) and (a + 3, b + 3). Substitute:

[tex]y-b=1(x-a)[/tex] - point-slope form

The formula for [tex]P(n,r)[/tex], which represents the number of permutations of r objects from a set of n distinct objects, is given by: [tex]\[ P(n,r) = \frac{n!}{(n-r)!} \][/tex]

To understand this formula, let's break it down:

1. [tex]\( n! \)[/tex] gives the number of ways to arrange n distinct objects in a sequence.

2. [tex]\( (n-r)! \)[/tex] gives the number of ways to arrange the remaining [tex]\( n-r \)[/tex] objects that are not chosen for the permutation.

3. Dividing [tex]\( n! \)[/tex] by [tex]\( (n-r)! \)[/tex] effectively cancels out the arrangements of the [tex]\( n-r \)[/tex] objects that we are not interested in, leaving us with the number of ways to arrange just the r objects.

Answer:

$2.50

Step-by-step explanation:

Let's take a look at the 4 orders and check the price per pup cake in each order:

Order 1: $5 for 2 cakes, so $2.50 per cake.

Order 2: $7.50 for 3 cakes, so $2.50 per cake.

Order 3: $12.50 for 5 cakes, so $2.50 per cake.

Order 4: $20.00 for 8 cakes, so $2.50 per cake.

Jake has a very consistent pricing of his cakes... they're always $2.50 each.

That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.

Answer:

Option 3rd is correct

$2.5 is the constant of proportionality in cost per pup cake

Step-by-step explanation:

The direct proportionality states that:

[tex]y \propto x[/tex]

then the equation is in the form of :

[tex]y = kx[/tex]              ....[1]

where, k is the constant of proportionality.

As per the statement:

The table shows how much Jake charged for the last 4 orders of pup cakes.

Let y represents the cost  and x represents the pup-cakes

Consider any values of x and y from the given tables.

x = 3 and y = $7.5

To find constant of proportionality in cost per pup cake.

Substitute these in [1] we have;

[tex]7.5 = 3k[/tex]

Divide both sides by 3 we have;

2.5 = k

or

k = 2.5

Therefore, $2.5 is the constant of proportionality in cost per pup cake

The distance the player throws the ball is [tex]112.5\ ft[/tex]

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABX

[tex]AB=90\ ft[/tex]

[tex]BX=(3/4)90=67.5\ ft[/tex]

XA --------> is the distance the player throws the ball (hypotenuse of the right triangle)

Applying the Pythagoras Theorem

[tex]XA^{2}=AB^{2}+BX^{2}[/tex]

substitute the values

[tex]XA^{2}=90^{2}+67.5^{2}[/tex]

[tex]XA^{2}=12,656.25[/tex]

[tex]XA=112.5\ ft[/tex]

The distance player throws the call was calculated using Pythagoras theorem and it is 112.5 feet.

It is given that

Side of the square = 90 feet

Distance of point x from the second base = 3/4 * 90 = 67.5

The distance the player throws the call let us say D will be the shortest distance between x and 1st base.

Distance D can be calculated by Pythagoras theorem

In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the perpendicular and the base.

[tex]D = \sqrt{90^{2} +67.5^{2} }[/tex]

[tex]D = \sqrt{8100+4556.25} \\\\D = \sqrt{12656.25\\}\\[/tex]

[tex]D=\sqrt{12656.25} = 112.5[/tex]

Therefore, the distance the player throws the call is 112.5 feet.
