Answers:

area = 50.24 square yards

circumference = 25.12 yards

values are approximate

================================================

Work Shown:

d = 8 is the diameter

r = 4 is the radius, half the diameter

pi = 3.14 approximately

C = 2*pi*r = circumference

C = 2*3.14*4

C = 25.12 yards is the circumference. The circumference is the distance around the circle, aka the perimeter

An alternative formula you can use is C = pi*d

-------------------

A = area of circle

A = pi*r^2

A = 3.14*4^2

A = 50.24 square yards is the area

Answer:

25.12 and 50.24

Step-by-step explanation:

8/2=4

4= radius

8= diameter

3.14*8=25.12

This would be the circumfrence (25.12)

3.14*4^2

3.14*16

50.24

This would be the area (50.24)

Hope this helps!

ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.

slava [35]

Answer:

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.

G=h(t) + p(c) is an equation that represents the gross pay of a server: Gross pay = hourly wage (time worked) + percent tip (cos

rusak2 [61]

Answer:

$105.5 for 16 hours at $6.59 per hour

Step-by-step explanation:

form the equation given, G=h(t) + p(c)

where G=Gross pay,

h= hourly wage

t=time worked

p=percent tip

c=cost of customer meals

we determine the gross pay by first determining the independent variables

h=$4.25, t=16 hours,

$p=15%of c\\p=\frac{15}{100}*250 \\p=37.5$

if we substitute values, we arrive at

$G=h(t)+p(c)\\G=4.25(16)+37.5\G=68+37.5\\G=105.5$

to determine the per hour gross pay we have

105.5/16

hourly gross pay,G=$6.59

maria [59]

Answer:

c = 1.5 d

cost of 1 small drink = $ $\frac{6}{4}$ = $1.5

cost of d small drinks = 1.5 d = c

∴ c = 1.5 d
