Answer:
The answer is below
Step-by-step explanation:
A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.
a) Given that number of chirps per minute, C is dependent on the temperature, T, when T = 45 degrees, C = 0, this can be represented as (45, 0).
Also at 75 degrees, C = 126 it can be represented as (75, 126).
Using (45, 0) and (75, 126), we can determine the equation of the line from:
b) At t = 90°:
C = 4.2(90) - 189
C = 189 chirps per min
Answer:
17/4 kg
Step-by-step explanation:
Sunita has = 10kg of grapes
Quantity given out :
To Reena =3 1/2
7/2 kg
To Anita =2 1/4
9/4 kg
Total quantity of grape given out
7/2+9/4
(14+9)/4
23/4
Quantity left after giving out = Total quantity of grape before giving out minus quantity of grape given out
10/1 - 23/4
40-23)/4
= 17/4 or 4 1/4
Hence, she has 17/4 kg of grape left with her
I assume it is asking for the surface area of a cylinder. A cylinder is composed of 2 parts. It has 2 circles and one rectangle. So lets solve for the circles:
The area is πr^2. Given our radius, 2, we can substitute into our r.
That gives us 4π. But since we have two circles, it is 8π
Next we solve for our rectangle. Our height is 4 and our base is 2πr or 4π
4 * 4π = 16π
Finally we add.
We get 16π + 8π = 24π ≈ 75.398 cm^2
Divide 3.6 by 14.4
14.4/3.6= 4
m=4
