Answer:
D. 28.26 in²
Step-by-step explanation:
Area of a circle= πr²
r= 3
π= 3.14
A= (3.14)(3)²
A= 28.26 in²
Answer:
<h2>y=2x+0 (y=2x)</h2>
Step-by-step explanation:
so we know that y=mx+c
c is the point where the line crosses the y-axis
y=mx+0
m is the gradient
the gradient is rise/run
pick any two points
so it is 2/1
2/1 is 2
therefore it is
y=2x+0
The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.
Step-by-step explanation:
Given,
Sale = 13% off
Number of bread purchased = 6
Original price of loaf of bread = b
The given expression is;
6(b-0.13b)
Expanding the expression;
6b-0.78b
5.22b
Here;
The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.
CD and ED are both radii of the circle, meaning they are equal to each other and equal x.
We can use the Pythagorean Theorem:
8^2 + x^2 = (4 + x)^2
64 + x^2 = 16 + 8x + x^2
Subtract x^2 and 16 from both sides:
8x = 48
x = 6
The answer is (B).
