Answer:

8 cm

Step-by-step explanation:

[(x+5)*2.5]/2 =  16.25

(x+5)*2.5 = 32,5

2.5x + 12,5 = 32,5

2.5x = 20

x = 8

Answer:

23,11333753

Step-by-step explanation:

1. Use The Coordinates To Find The Distances Of The Four Sides

2. The Formula For Perimeter Or A Quad =

AB + BC + CD + AD

Basically Add The Distances Of The Four Sides

So: WX + XY + YZ + WZ

[tex] \sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5} [/tex]

= 23,11333753

.°. 23,1

b.????

We can write the parameter as -

In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.

Given is that WXYZ has vertices W(6, 2), X(3, 7), Y(-1, 4), and Z(4, -2).

       {d} = √{(x₂ - x₁)² + (y₂ - y₁)²}

{ a } -

WX = 5.83

XY = 5

YZ = 7.8

ZW = 4.5

So the perimeter would be -

P = WX + XY + YZ + ZW

P = 5.83 + 5 + 7.8 + 4.5

P = 23.13

{b} - After the dilation, the sides will become -

WX' = 5.83/2 = 2.9

XY' = 5/2 = 2.5

YZ' = 7.8/2 = 3.9

ZW' = 4.5/2 = 2.25

The perimeter will be -

P = WX' + XY' + YZ' + ZW'

P = 2.9 + 2.5 + 3.9 + 2.25

P = 11.55

Therefore, we can write the parameter as -

Answer:

Step-by-step explanation:

3.3

Answer:

B

Step-by-step explanation:

Answer:

150.8cm

Step-by-step explanation:

Area= π r²

make r subject of the formula

A = π r²

A/π= πr² (dividing both sides by π)

r²= A/ π

r =

[tex] \sqrt{ \frac{a}{\pi} } [/tex]

r=√(1809.56)/(π)

r=√576.0008

r≈24cm

:. circumference= 2π r

= 2× π × 24

=150.7964

≈150.8cm

Answer:

7.5

35.2

1.5

20

Step-by-step explanation:

1. vertical angles are equal

(2x+17)=(4x+2)

15= 2x

x= 7.5

2. adjacent angles equal 180

(2m+8)+(3m-4)= 180

5m+4= 180

5m= 176

m= 35.2

3. (30s+5)=(20s+20)

10s= 15

s=1.5

4. 4p+5p=180

9p=180

p=20

sorry that took so long.  I was babysitting lol

Answer:

18 7/12 miles

Step-by-step explanation:

Luis is running a 26 mile marathon. He has completed 7 5/12 miles so far. How much farther does he have to run?

We solve the above question using the Subtraction operation

= 26 miles - 7 5/12 miles

= 26 miles - 89/12 miles

Lowest Common Denominator = 12

= 26/1 miles - 89/12 miles

= 312 - 89/12

= 223/12

= 18.583333333 miles

= 18 7/12 miles

He has 18 7/12 miles farther to go

Answer:

You simply just do 12 multiplied by 10 which will give you 120m^2

Answer:

[tex]\huge\boxed{Density = 3.52\ g/cm\³}[/tex]

Step-by-step explanation:

Given:

Mass = m = 1.76 g

Volume = v = 0.5 cm²

Required:

Density = ρ = ?

Formula:

ρ = m / v

Solution:

ρ = 1.76 / 0.5

ρ = 3.52 g/cm³

Answer:

1.341

Step-by-step explanation:

I'm smart at maths

Answer:

y = -2x + 8 (B)

Step-by-step explanation:

Just expand y + 2 = -2(x-5)

y + 2 = -2x +10

y = -2x +8 (minus both sides by 2)

Answer:

1. 168 cm^{2}

2. 156 in^{2}

3. 30 cm^{2}

4. 360 ft^{2}

Step-by-step explanation:

All ratio questions. We can set up proportions then cross multiply

1. \frac{8}{12} \frac{112}{x}

8x = (112 x 12)

8x = 1344

x = 168m

2.\frac{4}{8} \frac{78}{x}

4x = (78 x 8)

4x = 624

x = 156in

3. \frac{5}{2} \frac{75}{x}

5x = (75 x 2)

x = 30cm

4. \frac{8}{10} \frac{288}{x}

8x = ( 288 x 10 )

8x = 2880

x =360ft

Answer:

Circumference =

Step-by-step explanation:

The equation for finding the circumference of a circle is: C=2πr

All we need to do is plug in for r of the equation (which is the radius) and solve.

C = 2(3.14)·12

C = 6.28 · 12

C = 75.36 mill.

That is the circumference.

Answer:

I think its -15

Step-by-step explanation:

you take -7 and add it to -22 but since it's a negative + a negative it should equal a positive so you just normally subtract -7 from -22 and get -15
