Richard wants to make a garden with a perimeter of 16 feet, and length of 4 feet. He solves for the width by subtracting 8 from
Ostrovityanka [42]

The equation that can be used to solve this is:

P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W

Further explanation:

Let

P\ be\ the\ perimeter\\L\ be\ the\ width\\W\ be\ the\ width

The equation for the perimeter will be:

P =2W+2L

Given

P = 16 feet

L = 4 feet

W = ?

Putting the values in the perimeter formula

16=2(4)+2W\\16=8+2W\\16-8= 2L\\8=2L\\L=\frac{8}{2}\\L=4\ feet

The equation that can be used to solve this is:

P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W

a varies jointly as the square root of the product of b and c. if a = 24 when b = 8 and c= 2 , find v when a = 48 and c = 4​
____ [38]

Answer:

b = 16

Step-by-step explanation:

× stands for varies

a × √bc,

a = k√bc,

when a = 24, b = 8, c= 2

a = k√bc

24 = k√8•2

24 = k√16

24 = 4k

dividing both sides by 4

k = 24/4

k = 6

a = 6√bc (standard equation)

find b when a = 48 and c = 4

a = 6√bc

48 = 6√b•4

dividing both sides by 6

48/6 = √b•4

8 = √b•4

squaring both sides

8^2 = b•4

64 = b•4

b = 64/4

b= 16.

Thrrefore when a = 48, c = 4, b = 16.

Find the coordinate of the indicated point on a number line. Five-sixths of the distance from 1 to −13
Kazeer [188]

Answer: The coordinate is -10\frac{2}{3} or about -10.67

Explanation:

First, determine the distance from 1 to -13 on the number line:

d = |x_1-x_2|=|1-(-13)|=14

Next step is calculating Five-sixths of this distance:

\frac{5}{6}d=\frac{5}{6}\cdot14=\frac{35}{3}=11\frac{2}{3}

Finally, we "walk" that frcation of distance in the direction from 1 toward -13 (i.e., in the negative direction). The new coordinate x* is:

x^*=1-11\frac{2}{3}=-10\frac{2}{3}=-10.\overline{6}

Find mDF<br> Please help!!
Softa [21]

9514 1404 393

Answer:

  72°

Step-by-step explanation:

The external angle E is half the difference of the intercepted arcs.

  44° = (CD -DF)/2

  88° = CD -DF

  DF = CD -88° = 160° -88° = 72°
