There are two shapes
rectangle and triangle
Rectangle area = Length × breadth
Triangle area = ( 1 / 2 ) × height × base
L = 12
W = 5
Area = 60
Height = 14
base = width of rectangle
base = 12
( 1 / 2 ) ( 12 ) ( 14 )
( 14 ) ( 6 )
84
Total area = 60 + 84
= 144
Hope helps!
Step-by-step explanation:
step 1. what is the question? solve for x? okay.
step 2. 28/54 = (2x+ 8)/(5x - 4)
step 3. 28(5x - 4) = 54(2x + 8) (cross multiplication)
step 4. 14(5x - 4) = 27(2x + 8) (divide both sides by 2)
step 5. 70x - 56 = 54x + 216 (distributive property)
step 6. 16x = 272 (group x's and add 56 to both sides)
step 7. x = 17 (divide both sides by 16).
Answer:
At a point when r = 6 ft
The rate of change of Area with time is given as
(dA/dt) = 36π = 113.1 ft²/min
Step-by-step explanation:
Area of a circle, A = πr²
A = πr²
(dA/dt) = (dA/dr) × (dr/dt)
(dA/dr) = 2πr, (dr/dt) = 3
(dA/dt) = 2πr × 3 = 6πr
At a point when r = 6 ft
(dA/dt) = 6πr = 6π × 6 = 36π = 113.1 ft²/min
Hello!!
Well, there are 60 seconds in a minute, so all we have to do is multiply by 60.
13 * 60 = 780
The jogger runs a mile in 780 seconds.
Hope this helps!!
