20% is 20/100, 1/5, or 0.2
The number will decrease by a factor of 5.
Answer:
y = -2x + 10
Step-by-step explanation:
The equation is y = mx + b
1. Find the slope first.
--> (y2 - y1) / (x2 - x1) = slope
--> (-12 - -6) / (11 - 8) = (-6) / (3) = -2
2. Then, find the y-intercept (b) by plugging one of the points
--> y = -2x + b
--> -6 = -2(8) + b
--> -6 = -16 + b
--> b = 10
3. Combine
--> y = -2x + 10
Answer:
144km/hr
288km distance travelled
Step-by-step explanation:
40m/s
= 0.04km/(1÷60÷60)hr
= 144km/hr
distance = speed × time
d = 144 × 2
= 288km
Answer:
The correct answer is option C
Step-by-step explanation:
Area is usually the planar lamina of a two dimensional figure and usually expressed in units square meter, square feet, square inches etc.
While Volume is the total space occupied by an object in a 3-D setting and is usually expressed in cubic meter, cubic feet, cubic inches etc.
A 2-D dimension can not represent a 3-D structure and thus units of area inappropriate to measure volume
Let A be the surface area, l the length, w the width and h the height:
l= 12
w=8
h=8
A=2(wh+lw+lh)
A=2(8*8+12*8+12*8)
A= 512 m²
