15. the answer is 4/10 I think
Slope= 4; y-intercept= -3
y= mx+b ( slope intercept form)
m is also the slope
b is the y-intercept
answer:
y= 4x-3
18' by 15' simply means 18 feet by 15 feet.
simply convert feet into yards.
1 yard = 3 feet
18 feet * 1yd/3ft = 6 yards
15 feet * 1yd/3ft = 5 yards
Get the area in square yards:
6 yards x 5 yards = 30 square yards.
You should order 30 square yards of linoleum to cover your 18' by 15' kitchen.
Answer:
2,4,10
Step-by-step explanation:
Examples of even numbers: 2,4,6,8,10,12,14,16,18,20
Examples of odd numbers:
1,3,5,7,9,11,13,15,17,19,21
Answer:
1)Area; A = ¼πr²
Perimeter; P = πr/2 + 2r
2)A = 19.63 cm²
P = 17.85 cm
3) r = 8.885 cm
4) r = 14 cm
Step-by-step explanation:
This is a quadrant of a circle. Thus;
Area of a circle is πr². A quadrant is a quarter of a circle. Thus;
Formula for Quadrant Area is; A = ¼πr²
A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.
Formula for the quadrant perimeter in the image given is;
P = 2πr/4 + 2r
P = πr/2 + 2r
B) When r is 5 cm;
A = ¼π(5)²
A = 19.63 cm²
P = π(5)/2 + 2(5)
P = 17.85 cm
C) when A is 100cm²:
¼πr² = 100
r² = 100 × 4/π
r² = 78.9358
r = √78.9358
r = 8.885 cm
D) when P = 50 cm.
50 = πr/2 + 2r
50 = (½π + 2)r
r = 50/(½π + 2)
r = 14 cm
