Answer:

≈ 20 m

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ) , then

C = 2π × 3.2 = 6.4π ≈ 20

length of fence needed is approximately 20 m

In the figure, d, e, and f, are parallel lines. What is the value of x?
Aleks04 [339]

Answer:

x=150

Step-by-step explanation:

Since f is flat, that means that the total degrees will equal 180°.

Therefore, because of the 60° and (x-30)° angles being supplementary angles, 60+x-30 will equal 180.

60+x-30=180\\30+x=180\\x=150

At the fair 4 employees were paid $8.75 an hour to work at a funnel cake stand. They worked 8 hours at regular pay then for 5 ho
nordsb [41]

Answer:

$125.25

Step-by-step explanation:

8.75*h+11.25*e

h is hours regular pay and e is extra pay for overtime. Since its an extra $2.50 for overtime, add that to the regular pay. Put in the hours:

8.75*8+11.25*5

Simplify by multiplying 8.75 by 8

70+11.25*5

Simplify by multiplying 11.25 by 5

70+56.25

Add

70+56.25=126.25

Since it says how much did each earn, as in individually, leave it as it is (unless regular pay was $2.18 an hour, which would be a rip-off). I'm pretty sure including the number of employees was meant to throw you off.

using the two points find the slope then write the equation in slope intercept form AND standard form. (-6, 4) and (0, 3)
Paraphin [41]

so to find the slope we do y2- y1/ x2-x1

plug in the coordinates: (-6,4) (0,3)

3-4/ 0--6

3-4/0+6

= -1/6

Then using the formula of slop intercept form: y=mx+b........ use one of the coordinates to plug in

4= -1/6x+b...... multiply -6/1 on both sides of equation ( you do this so -1/6 and -6/1 can cancel out)

-24=b........ Use b to plug in y=mx+b---------> y= -1/6x-24
