Answer:

[tex]a^{2} +b^{2} =c^{2} \\9^{2} +20^{2} =c^{2} \\21.93=c[/tex]

Step-by-step explanation:

Answer:

A. 41

B. 1,590

C. .1

Step-by-step explanation:

A.

the equation is l*w=A

9.2*4.5=A

41.4=A

rounded it would be 41

B.

the equation is pi*r^2=A

3.14*22.5^2=A

3.14*506.25=A

1,589.6=A

^round this up to get 1,590

C.

what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)

.5*.2/2=A

.1/2=A

.05=A

.05+.05=0.1

Answer:

[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Part A:

The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].

What we're given:

Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]

Part B:

The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]

Part C:

The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].

What we're given:

Substituting given values, we get:

[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]

Step-by-step explanation:

In order to convert 45/8 to mixed number, you follow these steps :

Divide the numerator by the denominator. 45 ÷ 8 = 5 with a remainder of 5.

Write down the whole number 5 and then write down the remainder as new numerator (5) above the denominator (8), As below : 5 58

Answer:

3/42 or 1/14 if they have you reducing the number

Step-by-step explanation:

There are only 3 cans of black bean soup in the whole pantry. 3 is our numerator.

The denominator will be the total number of cans in the pantry, so

22 + 3 + 12 + 1 + 4 = 42

If you took a can of soup out of the pantry 42 times, 3 times it would be black bean soup

Answer:

there will be about 115 customer

Step-by-step explanation:

the y intercept is 2.5

(0,2.5)  (100 ,35)

the slope is (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = .325

y = mx+b

y = .325x+2.5

let y =40  for 40 cars in all the spot

40 = .325 x + 2.5

subtract 2.5

37.5 =.325 x

divide by .325

37.5 /.325 = x

115.4 = x

there will be about 115 customer

Answer:

-2 +19i

Step-by-step explanation:

(3 + 8i) − (5 − 11i)

Distribute the minus sign

(3 + 8i) − 5 + 11i

Combine the real parts together and the imaginary parts together

(3-5)+(8+11)i

-2 +19i

Answer:

The answer to the question is 19i -2

Answer:

An expression to represent the length of the side of the square with an area of 4x^2+12x+9 in terms of x is 2x + 3

Step-by-step explanation:

all sides of a square are equal in length.

area of a square is the side length squared.

area a, side s, variable x.

a = 4x^2 + 12x + 9.   s = ?   x = ?

a = s^2.

a = 4x^2 + 12x + 9.

4x^2 + 12x + 9 = s^2.

x^2 + 3x + 9/4 = (s^2)/4.

factor x^2 + 3x + 9/4 = (s^2)/4.

(x + 3/2)(x + 3/2) = (s^2)/4.

(x + 3/2)^2 = (s^2)/4.

√((x + 3/2)^2) = √((s^2)/4).

take positive root.

x + 3/2 = s/2

solve for side s.

s/2 = x + 3/2

s = 2x + 3

Answer:

(4, -3)

Step-by-step explanation:

(-4, -3) reflected y-axis => (4, -3)

Answer:

k = - 18

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 2

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, - 12) and (x₂, y₂ ) = (6, k)

m = [tex]\frac{k+12}{6-3}[/tex] = [tex]\frac{k+12}{3}[/tex] = - 2 ( multiply both sides by 3 )

k + 12 = - 6 ( subtract 12 from both sides )

k = - 18

Answer:

24 degrees

Step-by-step explanation:

The sum of the exterior angles of a triangle is 360 degrees

2x + 6x + 7x = 360

15x = 360

x = 24

Answer:

x=24

Step-by-step explanation:

2x+6x+7x=360
15x=360

15x/15=360/15
x=24

Answer:

Angle 1)  S = 12

Angle 2) Y = 18

Angle 3) R = 27

Angle 4) Z = 15

Angle 6) X = 13

Step-by-step explanation:

Angle 1

is a right angle, 90, use this to find s also

90 = (16s - 102)

90 + 102 = 16s

192/16 = s

12 = s

Angle 6

Angle 6 = 180

180 = 12x+24

180 - 24 = 12x

156 / 12 = x

13 = x

Angle 2

Angles 2 and 4 are a total of 90

Use this to find y

90 = (4y-9) + (y+9)

90 + 9 - 9 = 5y

90 = 5y

90/5 = y

18 = y

Angle 4

Angle 4 and 3 will be the same, us this to find z

2z - 3 = 4z - 33

2z - 3 - 4z = -33

-2z  = - 30

z = 15

Angle 3

3 and 5  together from 180

this mean

r + 5r + 18 = 180

6r = 180 - 18

6r = 162

r = 162 / 6

r = 27

Answer:

Length arc AB = 3.14 in

Step-by-step explanation:

Length of arc AB = central angle/360 * 2πr

Central angle = 30°

Radius (r) = 6 in.

Substitute

Length of arc AB = 30/360 * 2*π*6

Length arc AB = 3.14 in. (Nearest tenth)

Answer:

3.14

Step-by-step explanation:

its just right

Answer:

35°

Step-by-step explanation:

Angles on a straight line add up to 180, so 180-145 is equal to

Answer:

3 and -4

Step-by-step explanation:

this is simple but difficult

let the number be x and second number be y

3x + 2y=1

x-y/2=5

from the 2nd equation

x-y/2=5

x=5+y/2

substitute value for x into equation 1

3x + 2y=1

3(5+y/2) + 2y= 1

15 +3y/2 +2y=1

15 + 7y/2=1

7y/2= 1 - 15

7y/2=-14

cross multiply

7y= -28

y= -28/7

y= -4

therefore second number is -4

substitute value for y into 1st equation

3x + 2y=1

3x + 2(-4) = 1

3x - 8= 1

3x= 1+8

3x= 9

x= 9/3

x= 3

therefore first number is 3

therefore two numbers are;

3 and -4

Answer:

  BC = 6

Step-by-step explanation:

Tangents from the same point are congruent, so ...

  2x = x+3

  x = 3 . . . . . . . subtract x

  BC = x+3 = 3+3 = 6 . . . . . . substitute for x

The length of BC is 6.

Answer:

- [tex]\frac{2}{3}[/tex] and [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = S(12, 9) and (x₂, y₂ ) = T(21, 3)

[tex]m_{ST}[/tex] = [tex]\frac{3-9}{21-12}[/tex] = [tex]\frac{-6}{9}[/tex] = - [tex]\frac{2}{3}[/tex]

Repeat with

(x₁, y₁ ) = S'(4, 3) and (x₂, y₂ ) = T'(7, 1)

[tex]m_{S'T'}[/tex]  = [tex]\frac{1-3}{7-4}[/tex] = - [tex]\frac{2}{3}[/tex]

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

(x₁, y₁ ) = R(24, 18) and (x₂, y₂ ) = S(12, 9)

[tex]m_{RS}[/tex] = [tex]\frac{9-18}{12-24}[/tex] = [tex]\frac{-9}{-12}[/tex] = [tex]\frac{3}{4}[/tex]

Repeat with

(x₁, y₁ ) = R'(8, 6) and (x₂, y₂ ) = S'(4, 3)

[tex]m_{R'S'}[/tex] = [tex]\frac{3-6}{4-8}[/tex] = [tex]\frac{-3}{-4}[/tex] = [tex]\frac{3}{4}[/tex]
