Answer: 2π ft^2

Step-by-step explanation:

Area of a circle= π x the radius ^2

here your diameter is 4, and the radius is equivalent to half of the diameter so your radius equals 2.

A= π x 2^2

Answer:

x = 60°

Step-by-step explanation:

First find <E by applying the angles of intersecting chords theorem.

Based on the theorem, we would have the following equation:

m<E = ½(arc CA + arc BD)

Substitute

m<E = ½(170° + 70°)

m<E = ½(240)

m<E = 120°

Let's find x:

x = 180° - m<E (supplementary angles)

x = 180° - 120° (substitution)

x = 60°

Answer:

A

Step-by-step explanation:

Arc length is given by the formula:

[tex]\displaystyle s=2\pi r\frac{\theta}{360^\circ}[/tex]

Where r is the radius and θ is the central angle, in degrees.

The windshield wiper has a radius of 20 inches and a central angle of 150°. Hence:

[tex]\displaystyle s=2\pi (20)\left(\frac{150}{360}\right)[/tex]

Use a calculator:

[tex]\displaystyle s=\frac{50}{3}\pi \approx52.36\text{ inches}[/tex]

Our answer is A.

Answer:

[tex]|x - y| > 10[/tex] ---- Nita wins

[tex]|x - y| < 10[/tex] --- Eric wins

Step-by-step explanation:

The complete instruction is to determine the range at which Erik or Nita wins.

To start with, let

[tex]x \to[/tex] Erik's score

[tex]y \to[/tex] Nita's score

If the difference is greater than 10, the Nita wins.

This implies that:

[tex]|x - y| > 10[/tex] ---- Nita

If less than 10, then Eric wins

This implies that:

[tex]|x - y| < 10[/tex] --- Eric wins

Now, assume that Nita chose 5.

For Nita to win, we have:

[tex]|x - y| > 10[/tex]

[tex]|x - 5| > 10[/tex]

Remove the absolute symbol

[tex]-10 > x - 5 > 10[/tex]

Split

[tex]-10 > x - 5\ or\ x - 5 > 10[/tex]

Solve for x

[tex]5 -10 > x \ or\ x > 10 + 5[/tex]

[tex]-5> x \ or\ x > 15[/tex]

Rewrite as:

[tex]x< -5 \ or\ x > 15[/tex]

x cannot be negative.

So:

[tex]x > 15[/tex]

x cannot exceed 20.

So:

[tex]15 < x \le 20[/tex]

Answer:

425 grams divided by 28.3 = 1 ounce is about 15 ounces

Step-by-step explanation:

Since there are 425 grams in total and 28.3 GRAMS = 1 OUNCE that means. Every 28.3 grams in the total of 425 grams are ounces so we divide it by the 28.3 in order to find the ounces since every 28.3 grams are ounces!

Answer:

...............15 .................

Answer:

(a) No solution

(b) Infinitely many solution

(c) No solution

(d) Infinitely many solution

Step-by-step explanation:

Solving (a):

[tex]2x + 10y = 9[/tex] --- (1)

[tex]3x + 15y = 13[/tex] --- (2)

Multiply (1) by 1.5

1.5 * [[tex]2x + 10y = 9[/tex]]

[tex]3x + 15y = 13.5[/tex] --- (3)

Subtract 2 and 3

[tex]3x - 3x + 15y - 15y = 13.5 - 13[/tex]

[tex]0 = 0.5[/tex]

The above is false; Hence, the system has no solution

Solving (b):

[tex]2x + 8y = 5[/tex] --- (1)

[tex]3x + 12y = 7.5[/tex] -- (2)

Multiply 1 by 1.5

1.5 * [[tex]2x + 8y = 5[/tex]]

[tex]3x + 12y = 7.5[/tex]

Subtract 2 and 3

[tex]3x - 3x + 12y - 12y = 7.5 - 7.5[/tex]

[tex]0 = 0[/tex]

The above implies that the system has infinitely many solutions

Solving (c):

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

A second equation is required to solve for (c)

Solving (d):

[tex]5x - 8y = -1[/tex] --- (1)

[tex]-\frac{5}{2}x+ 4y = \frac{1}{2}[/tex] --- (2)

Multiply (2) by 2

[tex]-5x + 8y = 1[/tex] --- (3)

Add 1 and 3

[tex]5x - 5x -8y + 8y = -1 + 1[/tex]

[tex]0 = 0[/tex]

The above implies that the system has infinitely many solutions

Answer:

ST = 4

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle is half the length of the third side.

ST = [tex]\frac{1}{2}[/tex] PQ substitute values

- 32 + 9x = [tex]\frac{1}{2}[/tex] (- 5x + 28) ← multiply both sides by 2 to clear the fraction

- 64 + 18x = - 5x + 28 (add 5x to both sides )

- 64 + 23x = 28 ( add 64 to both sides )

23x = 92 ( divide both sides by 23 )

x = 4

Then

ST = - 32 + 9x = - 32 + 9(4) = - 32 + 36 = 4

Answer:

[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + c[/tex]

In which m is the slope and c is the y-intercept(value of y when x = 0).

A(2;2) and B(-3;4)

When we have two points, the slope is the change in y divided by the change in x. So

Change in y: 4 - 2 = 2

Change in x: -3 - 2 = -5

Slope: [tex]m = \frac{2}{-5} = -\frac{2}{5}[/tex]

So

[tex]y = -\frac{2}{5}x + c[/tex]

A(2;2)

When [tex]x = 2, y = 2[/tex]. We use this to find c.

[tex]y = -\frac{2}{5}x + c[/tex]

[tex]2 = -\frac{2}{5}(2) + c[/tex]

[tex]c = 2 + \frac{4}{5} = \frac{10}{5} + \frac{4}{5} = \frac{14}{5}[/tex]

So

[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]

Answer:

Option A: (23 + 29/30) miles

Step-by-step explanation:

Here we just need to add two mixed numbers.

(8 + 4/5) miles and (15 + 1/6) miles.

To add these, we just separate between the whole part and the fraction part:

(8 + 4/5) miles + (15 + 1/6) miles

= (8 + 4/5 + 15 + 1/6) miles

= (8 + 15 + 4/5 + 1/6) miles

= (23 + 4/5 + 1/6) miles

Now we need to find a common multiple between 6 and 5.

So, only analyzing the fraction part of the sum, we can rewrite:

4/5 + 1/6

= 4/5*(6/6) + 1/6*(5/5)

(notice that we are multiplying both numbers by one, so we do not change the expression's value)

= (4*6)/(5*6) + (1*5)/(6*5)

= 24/30 + 5/30

So now both fractions have the same denominator.

Then, replacing that in the sum equation we get:

(23 + 4/5 + 1/6) miles =  (23 + 24/30 + 5/30) miles

= (23 + 29/30) miles

Then the correct option is option A.

Answer:

Kevin made 5 free throws and 3 two-point shots.

Step-by-step explanation:

Given that Kevin scored 11 points in his last basketball game, to determine if Kevin made two more free throws (one point each) than two-point shots how many of each shot did he make, the following calculation must be performed:

11 x 1 + 0 x 2 = 11

6 x 1 + 4 x 2 = 14

5 x 1 + 3 x 2 = 11

Therefore, Kevin made 5 free throws and 3 two-point shots.

Answer:

40 feet

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a² + 9² = 41²

a² + 81 = 1681

Subtract 81 from both sides

a² = 1600

Take the square root of both sides

a = 40
