Answers

Answer 1

Answer:

Step-by-step explanation:

j=k+4

k=3r

j=3r+4

j+k+r=46

3r+4+3r+r=46

7r+4=46

7r=42

r=6, since k=3r

k=18, since j=k+4

j=22

j,k,r=22,18,6

Carter needs to remove sod in his yard to build three flower beds. One bed will be a rectangle which measures 2.5 m by 6 m. Another bed will be a semicircle which has a diameter of 6 m. The other bed will be a quarter circle with a radius of 4 m.

Answers

Answer:

[tex]Area = 41.714[/tex][tex]m^2[/tex]

Step-by-step explanation:

Given

Rectangle:

[tex]Length = 2.5m[/tex]

[tex]Width = 6m[/tex]

Semicircle

[tex]Diameter = 6m[/tex]

Quarter circle

[tex]Radius = 4m[/tex]

Required

The square meters of sod will Carter remove [Missing information]

To do this, we simply calculate the area of each flower beds.

For the rectangle:

[tex]A_1= Length * Width[/tex]

[tex]A_1= 2.5m * 6m[/tex]

[tex]A_1= 15m^2[/tex]

For the semicircle

[tex]A_2 = \frac{1}{2}\pi r^2[/tex]

Where

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

So:

[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 3^2[/tex]

[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 9[/tex]

[tex]A_2 = \frac{1*22*9}{2*7}[/tex]

[tex]A_2 = \frac{198}{14}[/tex]

[tex]A_2 = 14.143[/tex]

For the quarter circle

[tex]A_3 = \frac{1}{4}\pi r^2[/tex]

[tex]A_3 = \frac{1}{4} * \frac{22}{7} * 4^2[/tex]

[tex]A_3 = \frac{22}{7} * 4[/tex]

[tex]A_3 = \frac{88}{7}[/tex]

[tex]A_3 = 12.571[/tex]

Total area is:

[tex]Area = A_1 + A_2 + A_3[/tex]

[tex]Area = 15 + 14.143 + 12.571[/tex]

[tex]Area = 41.714[/tex][tex]m^2[/tex]

The formula for converting miles into feet is F = 5280m. If m = 12, evaluate this to find F, how many feet are in 12 miles. (Write the full equation, and then substitute for m.) *

Answers

Answer:

63360 feet

Step-by-step explanation:

The formula for converting miles into feet is F = 5280m. If m = 12, evaluate this to find F, how many feet are in 12 miles. (Write the full equation, and then substitute for m.) *

From the above question, we are given the expression:

F = 5280m

Where

F = Number of miles in feet

If m = 12 miles, the number of feet is calculated as:

F = 5280 × 12 miles

F = 63360 feet

A) y + 1/2 = 3/4 ( x + 1 ) ; y = 3/4x + 1/4
B) y − 1/2 = 3 ( x − 1 ) ; y = 3x − 1/4
C) y − 1/2 = 3/4 ( x − 1 ) ; y = 3/4x − 1/4

Answers

Answer:  C

Step-by-step explanation:

Find Slope first

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{2-.5}{3-1}[/tex]

[tex]m=1.5/2\\m=3/4[/tex]

Slope is 3/4

Chose a point to put in point slope form

(1,1/2)

y − y1 = m(x − x1)

[tex]y-\frac{1}{2} =\frac{3}{4} (x-1)[/tex]

[tex]y-\frac{1}{2} = \frac{3}{4}x-\frac{3}{4}[/tex]
