Answer:
A. x² +y² -6x -16y +48 = 0
Step-by-step explanation:
The standard-form equation for a circle centered at (h, k) with radius r is ...
(x -h)² +(y -k)² = r²
For your circle, this is ...
(x -3)² +(y -8)² = 5²
To put this in general form, you subtract the constant on the right, and eliminate parentheses:
x² -6x +9 +y² -16x +64 -25 = 0
x² +y² -6x -16y +48 = 0 . . . . . rearrange to descending powers of x, y
Answer:
£6
Step-by-step explanation:
Let
Plain scones = x
Cheese scones = 3x
Fruits scones = 4(3x)
= 12x
Total price of scones = £96
She sells each scone for the same price.
Total price of scones = Plain scones + Cheese scones + Fruits scones
96 = x + 3x + 12x
96 = 16x
Divide both sides by 16
x = 96/16
= 6
Plain scones = x = £6
Cheese scones = 3x
= 3(6)
= £18
Fruits scones = 4(3x)
= 12x
= 12(6)
= £72
How much does she make from the sale of the plain scones?
She made £6 from the plain scones
Answer:
√30/6 = √5
The correct answer would be E
Answer:
27.73 cm
1. Find the area of the rectangle: 8x7=56 cm
2. Find the area of the circle: pi x 3 squared= 28.2743338....cm
3. Subtract area of the circle from the area of the rectangle: 56 - 28.27433=27.72567cm
4. Round to the nearest hundredth: 27.73 cm
