Area of both the triangles :

= ½ × base × prepenicular

= ½ × 3 × 4

= 3 × 2

= 6 × 2 = 12 ( We have two triangles)

Area of semicircle :

= πr²/2

= 3.14 × 3 × 3 /2

= 28.26/2

= 14.13

Total area = 12 + 14.13 = 26.13 = 26.130

Two lines, A and B, are represented by equations given below:

Line A: y = x − 2
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

Group of answer choices:

A) (−3, −5), because the point does not lie on any axis

B) (−3, −5), because the point satisfies both equations

C) (−4, −8), because the point satisfies one of the equations

D) (−4, −8), because the point lies between the two axes

Answers

set the equations equal to each other to find x
x - 2 = 3x + 4
-6 = 2x
x = -3

plug x into either equation
-3 - 2 = y
y = -5

If ⅓y = 9; then y =?​

Answers

Answer:

y = 27

Eexplanation:

1/3y = 9

y/3 = 9

y = 9 × 3

y = 27

The answer is 27. We plug in 9 for y and get the equation 1/3(9). 1/3 times 9 equals 27.

C=10pi,  A = 25pi

Flower Bed B is the 5th one down

C=12pi, A=36pi

9514 1404 393

Answer:

  A) 10π ft; 25π ft²

  B) 12π ft; 36π ft²

Step-by-step explanation:

The circumference is given by ...

  C = πd = 2πr . . . . . . . . . . for radius r or diameter d

The area is given by ...

  A = πr² = (π/4)d²

__

A) For a diameter of 10 ft, the circumference is π(10 ft) = 10π ft.

The area is (π/4)(10 ft)² = 25π ft².

__

B) For a radius of 6 ft, the circumference is 2π(6 ft) = 12π ft.

The area is π(6 ft)² = 36π ft².

Which equation describes a circle with center (4,−7) and radius 9? A (x−4)2+(y+7)2=81 B (x+4)2+(y−7)2=81 C (x−4)2+(y+7)2=9 D (x+4)2+(y−7)2=9

Answers

Answer:

A. (x - 4)² + (y + 7)² = 81

Step-by-step explanation:

The general equation for a circle is given by the formula;

x² + y² + 2hx + 2ky + c = 0  ......equation 1.

Where the center is C(-h, -k)

Also, the standard form of the equation of a circle is;

(x - h)² + (y - k)² = r²  ......equation 2.

Where;

h and k represents the coordinates of the centre. r represents the radius of the circle.

Given the following data;

h = 4

k = -7

r = 9

Substituting into eqn 2, we have;

(x - 4)² + (y - {-7})² = 9²

Simplifying further, we have;

(x - 4)² + (y + 7)² = 81

Answers

Answer:

⅛

Step-by-step explanation:

Each mark (x) on the plot presents the distance that each student jumped.

There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.

Number of students that jumped 5½ ft = 3

Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

= 3/24

Alice is buying a

cost $120. It is on

the tax rate is 9.125%.

is the final amount cheaper or more expensive than the original price?

Answers

Answer:

NO

the final amount is 98.21 which is less than 120

Step-by-step explanation:

Price after discount = $120 x (100 - 25%)

$120 x 0.75 = $90

tax = $90 x 0.09125 = $8,21

final amount = $90 + 8.21 =  98.21

Seven television sets are chosen at random (i.e without replacement) from a shipment of 240 television sets of which 15 are defective. Calculate the probability that at least 1 of the chosen televisions are defective

Answers

Answer:

7/16

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

Proportion of defective televisions in the shipment = 15/240 = 1/16

Probability that 1 of the 7 chosen is defective = 1/16 x 7 = 7/16
