Answer:
The value of rate of which the base is changing 
= - 3 
Step-by-step explanation:
Area = 20 
height = 4 cm
we know that area of the triangle is given by
B = 10 cm
Rate of change of area is given by
![\frac{dA}{dT} = \frac{1}{2} [B\frac{dH}{dt} + H \frac{dB}{dt} ]](https://tex.z-dn.net/?f=%5Cfrac%7BdA%7D%7BdT%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5BB%5Cfrac%7BdH%7D%7Bdt%7D%20%2B%20H%20%5Cfrac%7BdB%7D%7Bdt%7D%20%5D)
4 = 0.5 [10 × 2 + 4 ]
= - 3
This is the value of rate of which the base is changing.
Step-by-step explanation:
A) Divide 1.68 into 3, the answer will be the answer to the question.
B) Times the answer to question a by 5

Answer:
Step-by-step explanation:
$60 * 3% = $1.80
y = 1.80x + $60
12 * 2 = 24
24 = x
y = 1.80(24) + $60
y = $43.20 + $60
y = $103.20
