The answer is 113 degrees because it’s supplementary you know you have to subtract it from 180 so 180-67=113

?+67. Have to equal 180 so you have to subtract 67 from 180 and that gives you 113.

180-67=113

A school needs 138 5 meters of fencing for a new playground Fencing is

Slav-nsk [51]

Answer:

12 Sections

Step-by-step explanation:

With 138.5 meters needed and fencing being purchased in 12-foot sections, you would need 12 sections purchased. 138.5/12=11.54, this is rounded up to 12 because of the purchase size.

The minimum distance between two fence posts is 4 feet. The maximum distance is 10 feet. A. Represent these two distances on a n

dybincka [34]

Answer:

Part A) The number line in the attached figure

Part B) The absolute value equation is $\left|x-7\right|=3$

Step-by-step explanation:

Part A) Represent these two distances on a number line

we know that

The minimum distance between two fence posts is 4 feet, and the maximum distance is 10 feet

Let

x ----> the distance between the two fence post

$4\leq x \leq 10$

The interval is -------> [4,10]

using a graphing tool

see the attached figure

In a number line the solution is the shaded area at right of x=4 (close circle) and at the left of x=10 (close circle)

Part B) Write an absolute value equation that represents the minimum and maximum distances

Find the midpoint of the interval [4,10]

$M=(\frac{x1+x2}{2})$

substitute the values

$M=(\frac{4+10}{2})$

$M=(7)$

The distance from the midpoint to the endpoints of the interval is 3 feet

The absolute value equation is

$\left|x-7\right|=3$

<em>Verify</em>

<u>Solve the absolute value</u>

case 1) positive value

$+(x-7)=3$

Solve for x

$x=7+3=10\ ft$ ----> maximum distance

case 2) negative value

$-(x-7)=3$

Solve for x

$-x+7=3$

$x=7-3=4\ ft$ ----> minimum distance

What is the answer to this math problem?

Over [174]

The volume of a sphere is 4/3 x π x (diameter / 2)3, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius3. Visual on the figure below:

Making this sphere's volume 904.778684 yd3 and its cubic yards is 1,183.4.

The graph shows how the mass of copper

Alex777 [14]

Answer: 8 1/4g/cm³

Step-by-step explanation:

Given the graph :

The rate of change in the mass of copper with respect to volume :

To obtain this, we find the slope or gradient of the graph:

Gradient = Δy / Δx = (y2 - y1) / (x2 - x1)

Drawing a right angled triangle on the anybpart of the line of best fit:

y2 = 40 ; x2 = 4.75 ; y1 = 16 ; x1 = 2

(y2 - y1) / (x2 - x1)

= (40 -16) / (4.75 - 2)

= 24 / 2.75

= 2400/275

= 8.727 g/cm^3

Due to unit and graph scale,, the slope is closest to 8 1/4g/cm³
