The blade covers an area of 235.714 square inches in one swipe.

In this question, we are to calculate the area that is covered by blade cover of the windshield wiper blade in 1 swipe.

To calculate this, we shall be using the formula for the area of the sector. The sector in this case subtends an angle of 120 degrees at the centre.

Mathematically, the area covered by the blade in one swipe is

A = θ/360 * pi * r^2

where θ = 120 degrees and r = 15 inch

A = 120/360 * 22/7 * 15^2

= 1/3 * 22/7 * 225 = 22 * 75/7 = 235.714 square inches

Answer:

y=1/8(-x^2+4x+44

Step-by-step explanation:

In this question the given focus is (2,4) and a directrix of y = 8 and we have to derive the equation of the parabola.

Let (x,y) is a point on the given parabola.Then the distance between the point (x,y) to (2,4) and the distance from (x,y) to diractrix will be same.

Distance between (x,y) and (2,4)

= √(x-2)²+(y-4)²

And the distance between (x,y) and directrix y=8

= (y-8)

Now √(x-2)²+(y-4)² = (y-8)

(x-2)²+(y-4)² = (y-8)²

x²+4-4x+y²+16-8y = y²+64-16y

x²+20+y²-4x-8y = y²-16y+64

x²+20-4x-8y+16y-64=0

x²+8y-4x-44 = 0

8y = -x²+4x+44

Step-by-step explanation:

To determine the number of ways to form a committee of 6 students from 30 council members, we use the combination formula C(30, 6), which yields 593,775 different combinations.

The question asks how many possible committees of 6 students can be formed from a group of 30 students on the student council. This is a combinatorial problem and can be solved using the combination formula which is given by C(n, k) = n! / (k! * (n - k)!), where C(n, k) is the number of combinations, n is the total number of items, and k is the number of items to choose. So to answer the question, we must calculate C(30, 6).

Calculating C(30, 6), we have:

C(30, 6) = 30! / (6! * (30 - 6)!)

C(30, 6) = 30! / (6! * 24!)

C(30, 6) = (30 × 29 × 28 × 27 × 26 × 25) / (6 × 5 × 4 × 3 × 2 × 1)

C(30, 6) = 593,775

There are 593,775 different ways to form a committee of 6 students from a student council of 30 members.

7. A- 5√2

9. C- 6√2

Step-by-step explanation:

Let's begin with question 7 asking to simplify √50.

We need to ask ourselves the question if 50 has a factor that is a square. It does!

We can break √50 into √25·2. Since 25 is a square, we can take it out of the radical by taking out its square root like this:

5√2.

For question 9, we can simply do the same exact process. √72 can be broken into a factor that is a perfect square as well!

√72 --> √36·2

Now, take the square root of 36 out of the radical to become:

6√2

Here are your answers!

Answer:

7 is A

Step-by-step explanation:

50 can be turned into 2 and 25 and you can simplify 25 into 5 giving you 5 to the square root of 2

Answer:

A.) 7x x 5=$50.00

Step-by-step explanation:

You can eliminate B and C as they don't include the 5 different stores.

D is incorrect because it doesn't include the 7 items.

Therefore, A is correct because 7x is the 7 items multiplied by the average cost per item and you multiply by 5 because she does that at each of the 5 stores. It = to 50 because she started with $65 but ends up with $15 so you subtract $65 with $15 to get $50 as that's how much she spent.

Answer:

A

Why:

$65.00-$15.00=$50.00

She visited 5 stores, and she bought 7 items.

So therefore it would be A.

Answer:

1/10

Step-by-step explanation:

In the question above we are given two data sets

a) A number cube labelled and it rolled, 1 to 6

b) A word called Music

We are asked to find the probability of

obtaining a 6 from the rolled dice and picking a consonant.

Step 1

Probability = Number of Possible Outcomes/ Number of events

Probability of obtaining a 6 from the rolled cube = P(6) = 1/6

Step 2

Probability = Number of Possible Outcomes/ Number of events

In the Letter MUSIC, we have 5 letters,

2 Vowels and 3 consonants

The Probability of Obtaining an Consonant = Number of possible outcomes ( Number of consonants) ÷ Number of events ( Number of letters in MUSIC)

P ( Consonant) = 3/5

Step 3

This is the final step

And we are to find the Probability of P(6 and consonant)

P( 6 and Consonant ) = P (6) × P ( Consonant)

P ( 6 and Consonant) = 1/6 × 3/5

= 3/30 = 1/10

Therefore, the Probability of obtaining P(6 and consonant) = 1/10.

Final answer:

The probability of rolling a 6 on a six-sided die and selecting a consonant from the word MUSIC is 1/10.

Explanation:

The probability of rolling a 6 on a number cube and selecting a consonant from the word MUSIC is found by multiplying the probabilities of the two independent events. The probability of rolling a 6 on a six-sided die is 1/6. The word MUSIC has three consonants: M, S, and C. The probability of choosing a consonant from MUSIC is 3/5, since there are 5 letters in total and 3 of them are consonants.

Therefore, the probability of both events occurring is:
P(6 and consonant) = P(6) × P(consonant) = (1/6) × (3/5) = 1/10.

We have been given that Mrs. Culland is finding the center of a circle whose equation is [tex]x^2+y^2+6x+4y-3 = 0[/tex] by completing the square. We are asked to find the final step of her work.

Let us complete the square.

We know that to complete square, we need to add the half the square of coefficient of x and y term.

[tex]x^2+y^2+6x+4y-3+3 = 0+3[/tex]

[tex]x^2+6x+y^2+4y=3[/tex]

We can see that coefficient of x is 6 and coefficient of y is 4.

[tex](\frac{6}{2})^2=3^2=9[/tex]

[tex](\frac{4}{2})^2=2^2=4[/tex]

Now we will add 9 and 4 on both sides as:

[tex]x^2+6x+9+y^2+4y+4=3+9+4[/tex]

[tex](x^2+6x+9)+(y^2+4y+4)=16[/tex]

Now we will complete the square as:

[tex](x+3)^2+(y+2)^2=4^2[/tex]

We know that standard form of equation of a circle is in form [tex](x-h)^2+(y-k)^2=r^2[/tex], where point (h,k) represents center of circle and r represents radius of circle.

We can rewrite our equation as:

[tex](x-(-3))^2+(y-(-2))^2=4^2[/tex]

Now we can see that center is at point [tex](-3,-2)[/tex].

Therefore, the equation of the circle would be [tex](x+3)^2+(y+2)^2=4^2[/tex] with a center at point [tex](-3,-2)[/tex].

Answer: The two answers are 1.08T and (1 + [tex]\frac{8}{100}[/tex] )T.

Step-by-step explanation:

Try multiplying 1.08 times any random number. If you use 5,  1.08 times 5 gives you 5.4.  This makes sense. Solve the other other expression as well and substitute T with the SAME number that you used before (5). Hope that helps!

The answer is 9 times. This is because if the radius of A is r, and the radius of B is 3r, the radii will be squared while finding the formula. So, r will become r squared, while 3r will become 9r squared.

5= -2x - 3

+3        +3

8= -2x

Divide by -2

-4= x

Final answer:

To find x when y = 5 in the equation y = -2x - 3, the solution is x = -4.

Explanation:

In the given equation y = -2x - 3, to find x when y = 5, substitute y with 5 in the equation:

5 = -2x - 3

Solve for x:

Add 3 to both sides: 5 + 3 = -2x

8 = -2x

Divide by -2: x = -4

Answer:

x = -4  and x = 2

Through the Completing the Square process below:

Step-by-step explanation:

solve 6x^2 +12x-48=0

first divide out the 6

x^2 + 2x - 8 = 0

Then use the Diamond method:

-8 = -2*4 ,   and  -2 + 4 = 2

so

x^2 - 2x + 4x - 8 = 0

x(x - 2) + 4*(x -2) = 0

(x + 4)(x - 2) = 0

so, solve  x + 4 = 0    and  (x - 2) = 0

x = -4  and x = 2

The completing the square is  {-4, 2}

Completing the Square. Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial . To solve a x 2 + b x + c = 0 by completing the square

According to the question,

Simplifying

6x2 + 12x - 48 = 0

Reorder the terms:

-48 + 12x + 6x2 = 0

Solving

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '6'.

6(-8 + 2x + x2) = 0

Factor a trinomial.

6((-4 + -1x)(2 + -1x)) = 0

Ignore the factor 6.

Set the factor '(-4 + -1x)' equal to zero and attempt to solve:

Simplifying

-4 + -1x = 0

Solving

-4 + -1x = 0

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

Add '4' to each side of the equation.

-4 + 4 + -1x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + -1x = 0 + 4

-1x = 0 + 4

Combine like terms: 0 + 4 = 4

-1x = 4

Divide each side by '-1'.

x = -4

Simplifying

x = -4

Set the factor '(2 + -1x)' equal to zero and attempt to solve:

Simplifying

2 + -1x = 0

Solving

2 + -1x = 0

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

Add '-2' to each side of the equation.

2 + -2 + -1x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + -1x = 0 + -2

-1x = 0 + -2

Combine like terms: 0 + -2 = -2

-1x = -2

Divide each side by '-1'.

8.7 x 8.7 = 75.69cm^2

75.69 x 13.1 = 991.539

991.539 ÷ 3 = 330.513 cm^3

Mark as brainliest please :)

Final answer:

The volume of a pyramid with a square base of side 8.7 cm and height 13.1 cm is calculated using the formula for volume, resulting in 330.35 cm³.

Explanation:

To find the volume of a pyramid with a square base, you can use the formula V = (1/3) × base area × height, where the base area for a square is given by side length × side length.

In this case, the side length of the base is 8.7 cm, and the height of the pyramid is 13.1 cm.

First, calculate the area of the base:

Base Area = 8.7 cm × 8.7 cm = 75.69 cm²

Then, calculate the volume of the pyramid:

Volume = (1/3) × 75.69 cm² × 13.1 cm = 330.35 cm³

Therefore, the volume of the pyramid is 330.35 cm³.
