What is the area of the following circle?
Either enter an exact answer in terms of pie or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.

Answer:

22.00x55%=12.10. 22-12.10=9.90

Answer:

$40

Step-by-step explanation:

22/55 = dollar per percent

dollar per percent = 0.4

0.4 x 100 will equal to 100% of the original price

0.4 x 100 = 40

to check, 40 x 55% = 22

Answer:

y = (x - 1)²

Step-by-step explanation:

A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.

The equation of a parabola with a horizontal directrix is given by:

(x - h)² = 4p(y - k).

Where the directrix (y) = k - p, vertex = (h, k)

Given that:  Vertex (1,0) and the Directrix y = -¼, Therefore:

vertex = (h, k) = (1, 0). h = 1 and k = 0.

y = k - p

but y = -1/4. Hence:

-1/4 = k - p

p = k + 1/4

p = 0 + 1/4

p = 1/4

Since the equation of the parabola is:

(x - h)² = 4p(y - k).

Substituting:

(x - 1)² = 4(1/4)(y - 0)

(x - 1)² = y

y = (x - 1)²

y = x² - 2x + 1

Answer:

Area of circle = 113.04 square feet

Step-by-step explanation:

Explanation:-

Given that radius of the circle (r) = 6 feet

Area of circle

                   A = π r²

                   A =  π (6)²

                  A =  36 π

                  A = 36 × 3.14

                  A = 113.04 square feet

Answer:

20.463

Step-by-step explanation:

3.59x5.7

5.7 pounds of coffee would cost  $20.463.

When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.

Given, Coffee costs $3.59 per pound. Since,

1 pound of coffee costs = 3.59$

5.7 pounds of coffee costs = 3.59 * 5.7

5.7 pounds of coffee costs = 20.463

Therefore, $20.463 would be the cost of 5.7 pounds of coffee.

Answer:

true

Step-by-step explanation: In a concave polygon, each interior angle is less than 180°.

Answer:

the trip would be 800 miles all together

Step-by-step explanation:

if you divide 240/3 it is 80 which means that 80 miles is 10% of the trip so you can multiply 80 by 10 to see that 800 miles is 100% of the trip.

Answer:

the correct answer is C. 75°

The value of ∠R = 75⁰

The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.

Given ΔQRS ≅ ΔXYZ

for congruency the sides and angle of both the triangles should be equal so for  ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and

∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y

from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z  = 50⁰

sum of angle of triangle is 180⁰,

∠Q + ∠S + ∠R = 180⁰

∠R  = 180 - 55 - 50

∠R  = 75⁰

Hence ∠R  = 75⁰

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]

☆All we need to do is plug in!

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]
