Step-by-step explanation:

multiply all of them

Answer:

54

Step-by-step explanation:

I have a big brain.... trust me.

Step-by-step explanation:

diameter = 20 inches

radius = diameter ÷ 2

radius = 20 ÷ 2

= 10 inches

circumference = 2π × radius

= 2 × 3.14 × 10

= 62.8 inches

Answer:

hi

Step-by-step explanation:

We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that  

(2x+y=20)*5

6x-5y=12

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

10x+5y=100

6x-5y=12  

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

16x = 112 .............After dividing 16 we get  

x = 7

Now we plug x  = 7 back into the original first equation to obtain the y value such that  

2(7) + y = 20  

12 + y = 20

-12         -12

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

y = 8

Step-by-step explanation:

Answer:

990 cm²

Step-by-step explanation:

Given ratio of radii = a : b , then

ratio of areas = a² : b²

Here

ratio of radii = 50 : 30 = 5 : 3 , then

ratio of areas = 5² : 3² = 25 : 9

let x be the area of sector DEF , then using proportion

[tex]\frac{25}{2750}[/tex] = [tex]\frac{9}{x}[/tex] ← [tex]\frac{ratio}{area}[/tex]

cross- multiply

25x = 24750 ( divide both sides by 25 )

x = 990

Area of sector DEF = 990 cm²

Answer:

Step-by-step explanation:

The formula for the circumference of a circle is C=2πr.

C = 2(3.14)(14) = 87.92

Answer:

1) 3/4

2)7/8

3)5/6

Step-by-step explanation:

1)

[tex] \frac{1}{2} \times 2 = \frac{2}{4} [/tex]

2/4+1/4=3/4

2)

[tex] \frac{1}{2} \times 4 = \frac{4}{8} [/tex]

4/8+3/8=7/8

3)

[tex] \frac{1}{2} \times 3 = \frac{3}{6} [/tex]

[tex] \frac{1}{3} \times 2 = \frac{2}{6} [/tex]

2/6+3/6=5/6

Answer:

[tex]x=2.\ y=1[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ the\ following\ pair\ of\ equations:\\5x+7y=17\\7x+5y=19\\Now,\\As\ the\ co-efficients\ of\ none\ of\ the\ algebraic\ terms\ match,\\We\ can\ take\ the\ LCM\ of\ their\ co-efficients;\\As\ the\ co-efficients\ of\ the\ x-terms\ are\ 5,7\ respectively;\\Their\ LCM\ is\ 35.[/tex]

[tex]Hence,\\7(5x+7y)=7(17)\\-5(7x+5y)=-5(19)\\Hence,\\35x+49y=119\\-35x-25y=-95\\Hence,\\Adding\ the\ two\ equations\ we\ have:\\(35x+49y)+(-35x-25y)=(119)+(-95)\\(35x-35x)+(49y-25y)=119-95\\24y=24\\y=\frac{24}{24}=1[/tex]

[tex]Now,\\Lets\ consider\ the\ First\ Equation:\\5x+7y=17\\Substituting\ y=1,\\5x+7*1=17\\5x+7=17\\5x=17-7\\5x=10\\x=\frac{10}{5}=2\\\\Together,\\x=2.\ y=1[/tex]

Answer: 12.152

Step-by-step explanation:

Answer:

12.15  or   875/72

Step-by-step explanation:

35/6 = 5.8333333

25/12 = 2.083333

or

35/6 turns to 70/12

70/12 x 25/12 = 1750/12  

1750/144 turns to 875/72

Answer:

17x+15 is your answer, I think it is A communative

Step-by-step explanation:

The property is illustrated in step 3 would be A commutative properties of addition

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

This property applies to multiplication also.

We are given the equation as;

5x + 1 + 12x + 4

= (5x + 1) + (12x + 4)

(5x + 12x) + (1 + 4)

Therefore, we can see that this shows the step of commutative properties of addition

Answer:

A. 31

Step-by-step explanation:

26 + 29 + 31 + 33 + 36 = 155

Average = 155/5 = 31

Answer: 30

Step-by-step explanation:

The perimeter of the given right triangle with hypotenuse 13 and base 5 is 30 units.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2  

We are given that;

hypotenuse=13, base=5

Now,

If the hypotenuse of a right triangle is 13 and one of the legs (also called the base) is 5, we can use the Pythagorean theorem to find the length of the other leg:

a^2 + b^2 = c^2

where a and b are the legs of the right triangle and c is the hypotenuse.

Substituting the given values, we get:

5^2 + b^2 = 13^2

Simplifying:

25 + b^2 = 169

b^2 = 144

b = 12

So, the length of the other leg is 12.

Now we can find the perimeter of the right triangle:

Perimeter = a + b + c

where a and b are the legs and c is the hypotenuse.

Substituting the given values, we get:

Perimeter = 5 + 12 + 13

Perimeter = 30

Therefore, by using pythagoras theorem the answer will be 30

============================================================

Explanation:

Place point F on line AB such that it is to the left of point A. In other words, point A is between points F and B.

Angle CAB is 105 degrees, so this makes angle CAF to be 75 degrees. This is because 105+75 = 180. The two angles are a linear pair.

Angle CAF is the angle formed between the tangent line AB and the chord segment AC.

Due to the tangent-chord theorem, inscribed angle CEA is also 75 degrees. Note how this inscribed angle subtends the arc cut off by the chord.

The inscribed angle theorem says we can double that inscribed angle to get 2*75 = 150, which is the measure of minor arc AC.

Arc CEA is therefore 360-(minor arc AC) = 360-150 = 210 degrees

Trapezoid area formula:

A=(base¹+base²/2)×height

Answer:

13.73 sq mm

Step-by-step explanation:

Area of Square - Area of Circle = Area of Shaded Region

if radius of circle is 4 then diameter is 8

the diameter is the same as the length of each side of the square

so area of square = 8² or 64

Area of Circle = 16π

64 - 16π ≈ 13.73
