A circular path 4 feet wide has an inner diameter of 550 feet. How much farther is it around the outer edge of the path than aro
Softa [21]

Answer:

L_c=25.12ft

Step-by-step explanation:

From the question we are told that

Width of circular path w_c=4ft

Inner Diameter d_i_n=550ft

Outer diameter d_{out}= 550 +2*4  (inner diameter +  2 circular path width)

d_{out}= 550 +8\\d_{out}= 558ft

Generally the equation for inner circumference of the circle C_1 is mathematically given by

C_1=\pi d_{in}

C_1=3.14*550

C_1=1727ft

Generally the equation for outer circumference of the circle C_2 is mathematically given by

C_2=\pi d_{out}

C_2=3.14*558

C_2=1752.12ft

Generally the difference in length of the two circumference L_c is mathematically given by

L_c=C_2-C_1

L_c=1752.12-1727

L_c=25.12ft

Please help me, thank you!​
Anon25 [30]

Answer:

a = 0.3

b = 0.4

c = 40%

d = 15%

Step-by-step explanation:

There are a total of 10 tick marks. So we know that 1 tick mark = 10%

a has 3 tick marks so you can say it's 0.3

b has 4 tick marks so you can say it's 0.4

c also has 4 tick marks, but it's asking for the percentage, so you get 40%

d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

5, 10.5, 22.05, 46.305, If it is a geometric sequence, choose the common ratio. If it is not a geometric sequence, choose "not g
kifflom [539]

Answer:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by  

2.1

gives the next term. In other words,  

a

n

=

a

1

⋅

r

n

−

1

.

Geometric Sequence:  

r

=

2.1

This is the form of a geometric sequence.

a

n

=

a

Substitute in the values of  

a

and  

r

=

Solve the equations
ASHA 777 [7]

Answer:

(1)The value of x is -9 .

Option (B) is correct .

(2)The value of x is 13 .

Option (A) is correct .

(3)The value of the x is 11 .

Option (D) is correct .

(4) The value of the x is -15 .

Option (A) is correct .

(5)The value of the x is -11 .

Option (C) is correct .

Step-by-step explanation:

First Part

As given

4x = -36

x = \frac{-36}{4}

x = -9

Therefore the value of x is -9 .

Option (B) is correct .

Second Part

As given

5x - 15 = 50

5x = 50 + 15gg

5x = 65

x = \frac{65}{5}

x = 13

Therefore the value of x is 13 .

Option (A) is correct .

As given

4(x+2)-17=35

4x + 8 - 17 = 35

4x = 35 + 17 - 8

4x = 44

x = \frac{44}{4}

x = 11

Therefore the value of the x is 11 .

Option (D) is correct .

Fourth Part

As given

6x+12=4x-18

6x-4x = -12-18

2x = -30

x = \frac{-30}{2}

x = -15

Therefore the value of the x is -15 .

Option (A) is correct .

Fifth Part

As given

\frac{1}{2}(4x-10)+5=x-11

Simplify the above

4x-10+5×2 = 2x-22

4x-10+10= 2x-22

4x-2x = -22

2x=-22

x = \frac{-22}{2}

x = -11

Therefore the value of the x is -11 .

Option (C) is correct .
