Find the value of x
.

Answer:

a = 8,059.52 m²

Step-by-step explanation:

Area of square

a = s²

a = 56²

a = 3,136

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

Area of circle

a = πr²

a = 3.14(56/2)²

a = 2,461.76

Area of 4 semicircles = area of 2 circles

a = 2,461.76 * 2

a = 4,923.52

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

Total area

a = 3,136 + 4,923.52

a = 8,059.52 m²

Answer:

585 miles

Step-by-step explanation:

divide 715 by 11 so that you can see the mph (miles per hour). Then multiply that number by 9 for the amount of miles he would travel in nine hours

Answer:

5y+3x=-9

Step-by-step explanation:

Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the slope-intercept form of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.

From this problem, we are given both the slope and the y intercept. We know have the equation:

[tex]y=-\frac{3}{5}x -3[/tex]

Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.

[tex]y+\frac{3}{5} x=-3[/tex]

This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.

[tex]5y+3x=-9[/tex]

I hope this helps! Please let me know if you have any questions :)

Answer:

[tex]y = 5x + 6[/tex]

Step-by-step explanation:

Parallel lines have the same slope

→ Since the equation is [tex]y = 5x - 3[/tex] and the form of a linear equation is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope, therefore 5 is the slope

Which creates the equation this far:

[tex]y = 5x + b[/tex]

→ Now, substitute the values of the point (-2, -4) into equation [tex]y = 5x + b[/tex]

[tex](-4) = 5(-2) + b[/tex]

→ Solve for [tex]b[/tex]

[tex]-4 = -10 + b\\-4 + 10 = b\\6 = b[/tex]

Resulting in the equation :

[tex]y = 5x + 6[/tex]

Answer:

139 degrees

Step-by-step explanation:

we only have a central angle here (angle at the center of the circle).

and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).

so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees

Answer:

A.) 4 x (y + 7)

Step-by-step explanation:

4 times means that you are going to be multiplying something by 4. It says 4 times the sum of y and 7. This means that you are going to multiply whatever y and 7 equal by 4. Sum means addition. So that's going to be that you are multiplying what the combined total of y and 7 is by 4.

Answer:

x = 51

Step-by-step explanation:

Supplementary angles total 180º

(2x + 4) + (x + 23) = 180

Combine like terms

3x + 27 = 180

Subtract 27 from both sides

3x = 153

Divide both sides by 3

x = 51

Answer:

Hello! x = 51

Step-by-step explanation:

OMG I CAN ANSWER FINALLY!

it is forming a supplementary angle meaning it will add up to 180 degrees

51 × 2 = 102 102 + 4 = 106

51 + 23 = 74

106 + 74 = 180 therefore x = 51 Hope that helps.

Answer:

4.44 cm²

Step-by-step explanation:

If the diagram attached below is required to complete the question,

Applying,

Area of the shaded segment(A) = Area of the sector- area of the triangle

A = (πr²∅/360)-(r²sin∅/)2................ Equation 1

Where r = radius of the circle, ∅ = angle at the center of the circle,π = pie

From the question,

Given: r = 5.4 cm, ∅ = 72°

Constant: π = 3.14

Substitute these values into equation 1

A = (3.14×5.4²×72/360)-(5.4²/2×sin72)

A = 18.31-13.87

A = 4.44 cm²

Answer:

f(x) = sin(x)

Step-by-step explanation:

sin(x) = 0 for x = n×pi, n>=0

sin(x) = 1 for pi/2 and so on

so, clearly that graph is a pure sine wave.

The equation in the problem solves the speed as 48.99 miles per hour. At this speed the car takes 100 feet to stop ( also shown in the equation as they replaced d with 100).

This means any speed below 48.99 miles per hour would stop before hitting the tree.

The fastest the car can go would be 48.98 miles per hour.

Justify by replacing s in the equation with 48.98 and solve for d:

48.98 ^2 = (sqrt( 30(0.8)d)

2399.04 = 24d

D = 2399.04/24

D = 99.96 feet

This is less than 100 feet so the car will not hit the tree.

Answer:

5

Step-by-step explanation:

6x + 4 + 73 + 73 = 180

6x + 150 = 180

6x = 30

x = 5

Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.

Triangle Sum Theory states all angles of a triangle add to 180.

Answer:

  (d)  15x -10y = -8

Step-by-step explanation:

Using the given values for slope (m) and y-intercept (b), the slope-intercept form of the equation is ...

  y = mx + b

  y = 3/2x +4/5

Multiplying both sides by 10 gives ...

  10y = 15x +8

Subtracting 10y+8 from both sides, we have ...

  -8 = 15x -10y

In standard form, this is ...

  15x -10y = -8

Answer: 16 inches

Step-by-step explanation:

To solve this question, we will use the Pythagoras theorem which will be:

Diagonal² = Length² + Width²

20² = 12² + width²

400 = 144 + width²

width² = 400 - 144

Width² = 256

Width = ✓256

Width = 16

The width of the tv is 16 inches

Answer:

4096

GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.

I hope it help you

The required 10th term of the geometric sequence 8, -16, 32 is -4,096.

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.

r = (second term) / (first term) = (-16) / 8 = -2

So the common ratio is -2.

The nth term of a geometric sequence is given by the formula:

[tex]a_n = a_1 * r^{(n-1)}[/tex]

where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.

To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:

[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]

Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.
