d.

Step-by-step explanation:

C=40+2s, c=20+4s

Step-by-step explanation:

let x be the another angle

so

x+40=90

x=90-40

x=50

The measure of missing angle is 50

Answer:

254 inches squared

Step-by-step explanation:

Hi there!

[tex]A=\pi r^2[/tex] where r is the radius of the circle

The radius is equal to half the diameter. Given that the diameter is 18 inches, we know that the radius of the circular plate is 9 inches. Plug this into the equation:

[tex]A=\pi (9)^2\\A=81\pi \\A=254[/tex]

Therefore, the area of the plate is approximately 254 inches squared.

If this is not an answer choice, the question may have been asking for the radius of the circle rather than the area.

I hope this helps!

Answer:

Using Pythagoras theorem we can find the missing length.

5^2 + 13^2

25 + 169 = 194

√194 = 13.9283882772 = around 13

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 → A

Answer:

y=17x -25

825 = 17x -25

850 = 17x

x = 850/17

x= 50

means 50h

and sorry second one i don't know

Answer:

a) 3C1 * 12 C1 / 15 C2

b)  1 - 12C2 / 15C2

Step-by-step explanation:

Được

Viên bi đỏ = 3

Viên bi trắng = 5

Viên bi xanh = 7

Hai quả bóng được rút ra một cách ngẫu nhiên

a) Có 1 bi đỏ

3C1 * 12 C1 / 15 C2

b) Có ít nhất 1 viên bi đỏ trong số 2 viên lấy ra.

Số kết quả của việc chọn hai quả bóng trong số 15 quả bóng = 15 C2

Số kết quả của việc chọn 0 quả bóng đỏ = 15C12

Xác suất chọn được ít nhất 1 viên bi đỏ = 1 - 12C2 / 15C2

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

he won a super bowl and he was able to read the defenses better he also achieved a lot without good receivers. Ryan had julio and Carson had Fitz know about brisket

1) x= 2, -4/3

2) x= 7, -4

i hope this is what you were asking

Answer:

x = -8

Step-by-step explanation:

The triangle is isosceles so the two angles are equal

Equation :

65 = x + 73

Subtract 73 from both sides

-8 = x

Check:

65 = -8 + 73

65 = 65

Answer:

C. 6 in

Step-by-step explanation:

Ratio length to width = 3:2

Given width = 4

Finding : Length

Ratio as fraction = 3/2

Fraction with width = x / 4

3/2 must equal x / 4 because they are proportional

3/2 = x/4

Cross multiply:

12 = 2x

x = 12/2

x = 6

Answer:

1 + i

Step-by-step explanation:

To rationalize multiply numerator and denominator by (2 + i )

[tex]\frac{3+i}{2-i}= \frac{3+i}{2-i} \times \frac{2+i}{2+i} = \frac{(3+i)(2+i)}{(2-i)(2+i)} = \frac{6+3i+2i-1}{4-(-1)} = \frac{5+5i}{5} = 1 + i[/tex]

Answer:

Faction of population = 1.39 / 7.2

Percentage of population = 19.3% (Approx.)

Step-by-step explanation:

Given:

China's population in 2014 = 1.39 billion (Approximately)

Find:

Compare China's population to world population

Computation:

World's population in 2014 = 7.2 billion (Approximately)

Faction of population = China's population in 2014 / World's population in 2014

Faction of population = 1.39 / 7.2

Percentage of population = [China's population in 2014 / World's population in 2014]100

Percentage of population = [1.39/7.2]100

Percentage of population = [0.193]100

Percentage of population = 19.3% (Approx.)

Answer:

Step-by-step explanation:

volume=πr^2h

461.58=3.14*r^2*12

461.58=37.68*r^2

461.58/37.68=r^2

12.25=r^2

[tex]\sqrt{12.25[/tex]=r

3.5=r

diameter=radius*2

=3.5*2

=7 in.

Answer:

Step-by-step explanation:

volume of a cylinder= base area times height or pie (r) squared * (h)

461.58=pie r squared h

461.58=3.14*r squared *12

461.58=37.68*r squared

please do the rest .

Answer:

143.7cm^2

Step-by-step explanation:

Given data

Volume= 576cm^3

Radius= 8cm

The expression for the volume of cylinder is

V= πr^2h

substitute

576= 3.142*8^2*h

576= 3.142*64*h

576= 201.088h

h= 576/201.088

h=2.86cm

The formula for finding the lateral area of a right circular cylinder is:

A=2πrh

substitute

A= 2*3.142*8*2.86

A= 143.7cm^2

Hence the area is 143.7cm^2

Answer:

Answer:

1 unit

Step-by-step explanation:

The circumference of a circle is given by

C = pi *d

Using pi  as 3.14

3.14 = 3.14 d

Divide each side by 3.14

1 = d

Answer:

1

Step-by-step explanation:

The formula for the circumference is πd where d is the diameter.

πd=3.14

Let's assume that π is around 3.14.

Isolate d, so you get d=1
