BD=10 because it is symmetrical to AD.
A decimal problem may be a addition problem you would need to regroup the hundredths to solve, like a money problem
2/a= a/50
Cross multiply:
a* a= 2*50
⇒ a^2= 100
⇒ a= √100 or a= -√100
⇒ a= 10 or a= -10
Final answer: a= 10 or a= -10~
Answer:
The scale factor used is 0.4
Step-by-step explanation:
Given
Required
Determine the scale factor of RST
The question can be solved using scale factor formula
Scale factor is calculated as thus;
In this case; R' is the new length and R is the old length
Substitute the values of R and R'
Factorize the denominator
<em>Hence, the scale factor used is 0.4</em>
We are given that the temperature is less than (<) -3 degrees Fahrenheit.
Since the temperature is represented by the variable "t", then t is less than -3.
So, the inequality which best describes the situation is:
t < -3
Checking the choices, we will find that the correct choice is:
<span>C: t < -3</span>
