Please help me find the area of this shape please!

Answer:

x= 21/15

if you need to reduce it would be x=7/5

Step-by-step explanation:

12x-15 =6-3x

add 3x to both sides

15x- 15 = 6

now add 15 to both sides

15x = 21

lastly divide both sides by 15

x= 21/15

if you need to reduce it would be x=7/5

Answer:

x = 7/5 or 1.4

Step-by-step explanation:

12x - 15 = 6 - 3x             Need to move one variable term to the other side to

+3x              + 3x         isolate it on one side

---------------------------

15x - 15 = 6                   need to +15 to isolate the variable term

     +15   +15

-----------------------

15/15x = 21/15 (simplify 21/15 = 7/5)   need to divide by 15 to isolate x

------------------------

x = 7/5 or 1.4

Answer:

Step-by-step explanation:

5555

The red arcs mean those angles are the same.

When two angles are the same the corresponding sides are also the same.

5. X = 8

6. X = 11

7. 2x-16 = 8

Add 16 to both sides:

2x = 24

Divide both sides by 2:

X = 12

8. X + 19 = 8

Subtract 19 from both sides:

X = -11

Answer:

A. 190 inches

Step-by-step explanation:

Plug in the numbers to the surface area formula  to get 190, i messed up last time

Answer:

$67400

Step-by-step explanation:

Given that :

Net income = 53246

Deduction (tax purposes) % = 21%

Gross income = net income + deduction

Let gross income = x

x = 53246 + 21% of x

x = 53246 + 0.21x

x - 0.21x = 53246

0.79x = 53246

x = 53246 / 0.79

x = 67400

Answer:

40

Step-by-step explanation:

6 * 10 = 60 papers done and complete

100- 60 = 40

Answer:

40 papers will be remaining

Step-by-step explanation:

= As,It take 1 hour to grade 6 papers

= 1 -6

= 10-?

= by cross multiplying we get 60 papers

= 100 - 60

= 40 papers

Thank you

Answer:

3 1/4 or 13/4

Step-by-step explanation:

Given:

The center of the circle is at (0,0).

The circle passes through the point A(4,-3).

To find:

The radius and the equation of the circle.

Solution:

Distance formula:

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

The radius of the circle is the distance between the points (0,0) and (4,-3).

[tex]r=\sqrt{(4-0)^2+(-3-0)^2}[/tex]

[tex]r=\sqrt{(4)^2+(-3)^2}[/tex]

[tex]r=\sqrt{16+9}[/tex]

[tex]r=\sqrt{25}[/tex]

[tex]r=5[/tex]

So, the radius of the circle is 5 units.

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is center of circle and r is the radius.

Putting h=0, k=0, r=5, we get

[tex](x-0)^2+(y-0)^2=5^2[/tex]

[tex]x^2+y^2=25[/tex]

Therefore, the radius of the circle is 5 units and the equation of the circle is [tex]x^2+y^2=25[/tex].

Answer:

8y+6y=288

Step-by-step explanation:

8y+6y= 12y

12y=288

12y divide by 12 = 288 divided by 12 =

y=24

Answer:

b=9 and b=-21

Step-by-step explanation:

first step: move 195 to the other side by adding to get:

b^2+12b=189

now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36

b^2+12b+36=189+36

next factor b^2+12b+36.

(b+6)^2=225

square root both sides to get:

b+6=15 and b+6=-15

solve by subracting 6 to both sides and you get the 2 final answers.

b=9 and b=-21

Answer:

157.1 m

Step-by-step explanation:

Here, we want to calculate the length of the semi-circle

This simply refers to the circumference of the semi-circle

Mathematically, the circumference is half that of a full circle

The circumference of a full circle is;

C = pi * d

For half circle or semi-circle;

It is ;

C = (pi * d)/2

D = 50 m

The circumference is thus;

C = 50 * 3.142

C = 157.1 m

50 yd
