Answer:
B
Step-by-step explanation:
C = R/1.8 - 273
C + 273 = R/1.8
1.8 * (C + 273) = R
1.8 can also be read as the fraction 9/5.
9/5 * (C + 273) = R
Thus your answer is B. Hope I helped!
Answer:
C
Step-by-step explanation:
a=r^2
To find the radius, divide the diameter by 2
r=d/2
r=10/2
r=5
a=r^2
a=5^2
a=25
So, choice C is correct
Hope this helps! :)
The answer is 13. You can find this out by using the PEMDAS method. (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.)
Answer:
an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Step-by-step explanation:
Assume that the spring behaves linearly so that
y = a + bx
where
x = weight of the mass
y = stretch of the spring
a,b are constants
When x = 70 g, y = 22 cm, therefore
a + 70b = 22 (1)
When x = 105g, y = 27 cm, therefore
a + 105b = 27 (2)
Subtract (1) from (2).
a + 105b - (a + 70b) = 27 - 22
35b = 5
b = 0.1429
From (1), obtain
a = 22 - 70*0.1429 = 12
Answer:
The required equation is
y = 12 + 0.1429x
