  • Circumference of a Circle Formula: C = πd

Step-by-step explanation:

<u>Step 1: Define</u>

Circumference <em>C </em>= 141.3 ft

<u>Step 2: Solve for </u><em><u>d</u></em>

  1. Substitute in <em>C</em> [Circumference Formula]:                                                       141.3 ft = πd
  2. Substitute in π (approximation):                                                                      141.3 ft ≈ 3.14d
  3. [Division Property of Equality] Divide both sides by 3.14:                              45 ft ≈ d
  4. Rewrite:                                                                                                             d ≈ 45 ft

(07.03 LC) The steps below show the incomplete solution to find the value of q for the equation 4q − 2q − 4 = −1 + 21: Step 1: 4
Elza [17]

Answer:

3: 2q − 4 = 20

Step-by-step explanation:

Solve for q:

2 q - 4 = 20

Add 4 to both sides:

2 q + (4 - 4) = 4 + 20

4 - 4 = 0:

2 q = 20 + 4

20 + 4 = 24:

2 q = 24

Divide both sides of 2 q = 24 by 2:

(2 q)/2 = 24/2

2/2 = 1:

q = 24/2

The gcd of 24 and 2 is 2, so 24/2 = (2×12)/(2×1) = 2/2×12 = 12:

Answer:  q = 12

A segment has endpoints (14,-8) and (4, 12). What are the coordinates of<br> its midpoint?
lutik1710 [3]

Answer:

(9,2)

Step-by-step explanation:

To find the x coordinate of the midpoint, average the x coordinates of the endpoints

(14+4)/2 = 18/2 = 9

To find the y coordinate of the midpoint, average the y coordinates of the endpoints

(-8+12)/2 = 4/2 = 2

On a coordinate plane, a line is drawn from point j to point k. point j is at (negative 15, negative 5) and point k is at (25, 1
Genrish500 [490]

The required x- and y- coordinates of point e, which partitions the directed line segment is (17, 11)

<h3>Midpoint of coordinates</h3>

The middle point of two coordinates is known as its midpoint. The formula for calculating the midpoint of a coordinate is expressed as:

m(x,y)=(\frac{mx_1+nx_2}{m+n},  \frac{my_1+ny_2}{m+n})

Given the coordinate points J(-15, -5) and k(25, 15) partitioned in the ratio 1:4, the x- and y- coordinates of point e, which partitions the directed line segment is given as:

m(x,y)=(\frac{1(-15)+4(25)}{1+4},  \frac{1(-5)+4(15)}{1+4})\\m(x,y)=(\frac{85}{5}, \frac{55}{5} )\\m(x, y) = (17,11)

Hence the required x- and y- coordinates of point e, which partitions the directed line segment is (17, 11)

What is 9 6/9 - 4 8/9
NeX [460]
The answer is 4 7/9.

Since you cannot subtract the numerators, you have to take 1 from the whole number, so 9 turns into 8 and you add the denominator to the numerator to make the equation 8 15/9 - 4 8/9 which is 4 7/9 :).
