Answer:

A.5/12

Step-by-step explanation:

Answer:5/12

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(3)

The opposite sides of a parallelogram are congruent, so

6x = 3x + 15 ( subtract 3x from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

2y - 10 = y + 5 ( subtract 5 from both sides )

y - 10 = 5 ( add 10 to both sides )

y = 15

Then x = 5 and y = 15

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

(4)

The diagonals of a parallelogram bisect each other, thus

y = 4x - 6 → (1)

9x - 25 = 2y → (2)

Substitute y = 4x - 6 into (2)

9x - 25 = 2(4x - 6)

9x - 25 = 8x - 12 ( subtract 8x from both sides )

x - 25 = - 12 ( add 25 to both sides )

x = 13

Substitute x = 13 into (1)

y = 4(13) - 6 = 52 - 6 = 46

Then x = 13 and y = 46

Answer:

b = 5.2

c = 3.5

Step-by-step explanation:

By 45°- 45° - 90° triangle theorem:

[tex]c = \frac{1}{ \sqrt{2} } \times 5 \\ \\ c = \frac{1}{ 2} \times 5 \sqrt{2} \\ \\ c = 2.5 \times 1.414\\ \\ c = 3.535 \\ \\ c \approx \: 3.5[/tex]

By 30°- 60° - 90° triangle theorem:

[tex] b = \frac{ \sqrt{3} }{2} \times (2 \times 3) \\ \\ b = 3 \sqrt{3} \\ \\ b = 3 \times 1.732 \\ \\ b = 5.196 \\ \\ b \approx 5.2[/tex]

Answer:

7.5

Step-by-step explanation:

157.5/21 = 7.5

Answer: x = 13

Step-by-step explanation:

To find the value of x, you have to find ∠QRP

∠QRP + ∠QRS = 180

∠QRP + 95 = 180

Subtract 95 from both sides

∠QRP = 85

∠RQP + ∠QPR + ∠QRP = 180   Definition of triangle

(4x + 3) + (3x + 1) + 85 = 180

Subtract 85 from both sides

(4x + 3) + (3x + 1) = 95

7x + 4 = 95

Subtract 4 from both sides

7x = 91

Divide 7 from both sides

x = 13

60 degress

Step-by-step explanation:

1. Find out the angel of each side. 360 divded by 6 = 60

2. Get the answer of 60

Answer:

68

Step-by-step explanation:

81 +81 is 162

298-162=136

136/2=68

Step-by-step explanation:

Let x be the number of points the 5 girls scored.

=> 41 - x is the number of points the 2 boys scored.

We have x + 29 = 41 - x or x - 29 = 41 - x.

=> 2x = 12 or 2x = 70

=> x = 6 or x = 35

We reject x = 6 as 6 is not a multiple of 5. (Each girl would have scored 1.2 points which is absurb)

So x = 35, each girl scored 35/5 = 7 points.

=> 41 - (35) = 6, each boy scored 6/2 = 3 points.

Answer:

The 1st one

Step-by-step explanation:

Answer:

-56=8(x-8)

-56=8x-64 +64

8=8x :8

1=x

Step-by-step explanation:

prove me wrong

Answer:

x=1

Step-by-step explanation:

You would do distributive property and multiply 8 by the x and -8

-56=8x-64

The add 64 on both sides

8=8x

divide 8

x=1

Answer:

y = - x + 4

Step-by-step explanation:

The first step is to find the slope-intercept form, which is:

y=x-6.

Then, y=x+6

y=-x+4 should be the answer since it passes through the point (-1, 5)

Answer:

y=x+6

The solution for pi is π = 2A/r² where r is the radius.

The area of a circle is defined as the space occupied by the circle in a two-dimensional plane. In other word, the space occupied under the region or circumference of a circle is called the area of the circle.

The formula for the area of a circle is A = πr²,

Where r is the radius of the circle.

For example, if the radius of circle is 6cm, then its area will be: Area of a circle with 6 cm radius = πr² = π(6)² = 36π square cm.

Given data as :

A = 1/2 πr²

Solve for pi

⇒ A = 1/2 πr²

Multiply by 2 both the side

⇒ 2A =  πr²

⇒ 2A/r² =  π  or

⇒  π = 2A/r²

If A = 76 cm² and π  = 22/7,

⇒ A = πr²

⇒ A/π = r²

⇒ √A/π = r

Substitute the values, we have:

⇒ √76 /(22/7) = r

⇒ √76 * 7/22 = r

⇒ √532/22 = r

⇒ √24.1818 = r

⇒ 4.917 = r

⇒ r = 4.92 cm (Rounding to two decimal places)

The question seems to be incomplete the correct question would be

If A = 76 cm² and π  = 22/7, what is the value of r in centimeters?

Answer:

2x+2

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

12x+10 = 2(4x+3) + 2 * width

12x+10 = 8x + 6 + 2w

4x+4 = 2w

2x+2 = w

sin 54   =     26

x sin 54 = 26

x sin 54      =         26    

sin 54                sin 54

1 millilitre = 0.001 litre

1 litre = 1000 millilitres

9 millilitres = 0.009

9 litres = 9000 millilitres

1,000 millilitres = 1 litre

1,000 litres = 1e+6

350 millilitres = 0.35 litres

350 litres = 350000 millilitres
