Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

X - 5y = 20

x - 20 = 5y

(x - 20) / 5 = y

x = - 5

y = (-5 - 20) / 5 = -5

x = 0

y = (0 - 20) / 5 = - 4

x = 5

y = (5 - 20) / 5 = - 3

x = 10

y = (10 - 20) / 5 = - 2

X : _____ - 5 ___ 0 ____ 5 ____10

y : _____ - 5 ___- 4 ___ - 3 ___ - 2

Kindly make use of a graph for better clarity and accuracy

fenix001 [56]

Answer:

Market price of set = 25.14

Step-by-step explanation:

Given:

Discount percentage = 20%

Service charge = 10%

GST = 7%

Amount pays = 23.54

FInd:

Market price of set

Computation:

Assume;

Market price of set = a

Market price of set after discount = a(1-20%)

Market price of set after discount = 0.80a

Market price of set after discount + (Market price of set after discount)(Service charge) + (Market price of set after discount)(GST) = Amount pays

0.80a + (0.80a)(10%) + (0.80a)(7%) = 23.54

0.80a + 0.08a + 0.056a = 23.54

0.936a = 23.54

a = 25.14

Market price of set = 25.14

A giant pie is created in an attempt to break a world record for baking. The pie is shown below: A circle is shown with a centra
lisabon 2012 [21]

Answer:

a. 22.08 ft^{2

Step-by-step explanation:

d = diameter = 15ft; r = (1/2)d = 7.5ft; A=area

So, A = (π) × r^{2}

A = (π) × (7.5ft)^{2}

A = (π) × (56.25ft^{2})

The entire circle is 360°, so 45 is \frac{1}{8}.

A(slice) = (\frac{56.25}{8}) × ft^{2} π

A(slice) = 7.03 × (π) × ft^{2}
