What is the formula of area of a quadrant?​

Answers

Answer 1

Answer:

that is, pi (π) multiplied by the radius squared (r2). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr2)/4 Square units.

Consider the figure shown below. Find the value of BL

Answers

Answer:

BL = 2

Step-by-step explanation:

Given:

AL = 3

AC = 10

BC = 9

AL = AM = 3 (tangents drawn form am external point)

CM = AC - AM

CM = 10 - 3

CM = 7

CM = CN = 7 (tangents drawn form am external point)

BN = BC - CN

BN = 9 - 7

BN = 2

BN = BL = 2 (tangents drawn form am external point).

BL = 2

Write the equation for a line containing the point (0,2) and a slope of -7 (y=mx+b)

Answers

Y = -7x + b
2 = 0 + b, b = 2
Y = -7x + 2

Answer:

[tex]y=-\frac{7}{1}x+2[/tex]

Step-by-step explanation:

The slope of -7=

[tex]-\frac{7}{1}[/tex]

so fractional slope is

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

Substituting slope into a fraction,

[tex]y=-\frac{7}{1} x+b[/tex]

Point is 0,2 so substitute in x and y.

[tex]2=-\frac{7}{1} (0)+b[/tex]

Solve the equation.

[tex]b=2[/tex]

So the equation for the line is

[tex]y=-\frac{7}{1}x+2[/tex]

A student who is training for a distance race jogged for thirty minutes and covered a distance of 7.5 km. What is the average speed of the student?

Answers

Answer:

Average speed is 15km/h

Step-by-step explanation:

Step one:

given data:

total distance =7.5km

time taken= 30 min= 0.5 hours

we know that the average speed is the average distance divided by time taken

Step two:

mathematically expressed as

speed=distance/time

substituting we have

speed=7.5/0.5

speed=15km/hour

Hence the average speed is 15km/h

6k ÷ 7 = -3
Solve for k

Answers

Answer:

k = -3.5

Step-by-step explanation:

6k ÷ 7 = -3

Multiply 7 to both sides

6k = -21

Divide both sides by 6

6k/6 = -21/6

k = -3.5

To check if the answer is correct or not, you can always plug in -3.5 for k in the equation.

6(-3.5) ÷ 7 = -3

-21 ÷ 7 = -3

-3 = -3

-3 equals -3 so it is correct that k = -3.5

Describe two different ways to solve 8y + 22 = 2y – 12 and tell whether the two solutions will be the same.

(written response)

Answers

8y+22=y-12

First way:
—> subtract 2y and 22 from both sides to get 6y= -34
—> divide both sides to get 3y= -17
—> divide both sides by 3 to get y= -(17/3)

Second way:
—> add 12 to both sides and -8y from both sides to get -6y= 34
—> divide both sides by 2 to get -3y= 17
—> divide both sides by -3 to get y= -(17/3)

There are at least 2 other ways to solve this. This is just two ways. The solution will ALWAYS be the same if you have done it correctly. Y will always = to -(17/3)
