Given:

A figure of a circle and inscribed quadrilateral JKLM.

[tex]m\angle M=47^\circ,\angle K=(7x+21)^\circ[/tex]

To find:

The value of x.

Solution:

The inscribed quadrilateral JKLM in the circle I is a cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles.

Angle M and angle K are opposite angles of a cyclic quadrilateral, it means they are supplementary angles and their sum is 180 degrees.

[tex]m\angle M+m\angle K=180^\circ[/tex]

[tex]47^\circ+(7x+21)^\circ=180^\circ[/tex]

[tex](7x+68)^\circ=180^\circ[/tex]

[tex](7x+68)=180[/tex]

Isolate the variable x.

[tex]7x=180-68[/tex]

[tex]7x=112[/tex]

[tex]x=\dfrac{112}{7}[/tex]

[tex]x=16[/tex]

Therefore, the value of x is 16.

Answer:

[tex]6\frac{2}{3}[/tex]

Step-by-step explanation:

When one multiplies fractions, one must first ensure that both fractions are in the improper fraction format. This can be done by multiplying the number next to the fraction by the denominator of the fraction then adding the result to the numerator,

[tex]8\frac{1}{3} * \frac{4}{5}\\\\= \frac{24+1}{3} * \frac{4}{5}\\\\= \frac{25}{3}*\frac{4}{5}[/tex]

Now cross simplify, remove factors that the numerator and denominator have in common,

[tex]\frac{5}{3}*\frac{4}{1}[/tex]

Finally, multiply, multiply the numerator of the first fraction with the numerator of the second fraction, and the denominator of the first fraction with the denomaintor of the second fraction.

[tex]\frac{20}{3}[/tex]

Convert the result to a mixed number. This can be done by dividing the numerator by the denominator, write the result to the left of the fraction, and the remainder as the numerator,

[tex]6\frac{2}{3}[/tex]

Answer:

72π

Step-by-step explanation:

Please see the attached image. r is the radius and h is the height.

The radius is half the diameter, so it is 6/2=3.

The height is given, 8.

Knowing the radius is 3 and the height is 8, all we need to do is plug it into the formula.

Volume=π3^2*8

=72π

or

≈226.19

Answer:

Y=-9

W=9

Step-by-step explanation:

2y/6+3=0

-3=-3

6/1 *2y/6=-3*6/1

2y=-18

2y/2=-18/2

Y=-9

Answer:

x² - 6x + 9

Step-by-step explanation:

(a - b)² =a² - 2ab + b²

a = x and b = 3

(x - 3)² = x² - 2*x*3 + 3²

           = x² - 6x + 9

Answer:

x^2-6x+9

Answer:

ange is 7

Step-by-step explanation:

Angle 5 plus angle 7 sum is 180 degrees because the are supplementary angles. Therefore, 85 degrees + unknown angle 7= 180. 180-85= 95 degrees, or the measurement of angle 7.

Answer:

47.3

Step-by-step explanation:

A triangles angles add up to 180 degrees

At 42.7 and 90 and you get 132.7

Subtract 132.7 from 180 and you get 47.3 degrees.

Answer:

A. 47.3°

Step-by-step explanation:

The sum of all the angles in a triangle equals 180°, so we need to subtract 42.7° and 90° from 180° to get ∠N.

180° - 90° - 42.7° = 47.3°

∠N = 47.3°

Answer:

answer is x=6 .

Step-by-step explanation:

10+(50×5)=260

10+(50×6)=310

10+(50×7)=360

so 10+300= 310 showing it 310 is greater that or equal to 50×6+10=310

Step-by-step explanation:

if 1inch=1/2 miles

then,1/2×12

___________

1

=1/2×12

=24 inches

Answer:

divide both sides by 2 (to isolate the equation in parenthesis)

subtract 3 from both sides (to isolate the variable x)

x=1

Step-by-step explanation:

Answer:

She worked 12 hours for the week

Step-by-step explanation:

Given that :

Hours worked :

Mondays = 40 hours

Tuesdays = 8 hours

If 1/4 of regular hours was worked in a certain week, the number of hours worked that week can be calculated thus ;

1/4 (Monday hours + Tuesday hours)

1/4(40 + 8)

(1/4 * 40) + (1/4 * 8)

10 + 2

= 12 hours

Answer:

Answer:

3/2

Step-by-step explanation:

My reasoning is that the sum of the numbers in the left is equal to the sum of the numbers in the right.

Therefore 6=2y+3

2y=6-3

2y=3

y=1.5 or 1and a half which is equivalent to 3/2

Step-by-step explanation:

8÷2(2+2) = 8.

2(2 + 2)

Answer:

A n B = {6}

Step-by-step explanation:

Given he sets A = (even numbers less than 10) and B = (multiples of 3 greater than 3)

A = {2, 4, 6, 8}

B = {3, 6, 9, 12, 15...}

A n B includes the numbers are are common to both sets i.e number that we can find in both A and B.

From the set given, we can see that the only number that exists in both set is 6, hence;

A n B = {6}
