what is 2/a = a/50. These are factions if you already didn't know. I need to know what the answer is. it is a proportion.
Natalija [7]
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~

RST is dilated about the origin,O, to creat R’S’T’. Point R is located at (3,9) and point R is located at (1.2, 3.6). Which scal
sashaice [31]

Answer:

The scale factor used is 0.4

Step-by-step explanation:

Given

R = (3,9)

R' = (1.2, 3.6)

Required

Determine the scale factor of RST

The question can be solved using scale factor formula

Scale factor is calculated as thus;

Scale\ Factor = \frac{New\ Length}{Old\ Length}

In this case; R' is the new length and R is the old length

Scale\ Factor = \frac{R'}{R}

Substitute the values of R and R'

Scale\ Factor = \frac{(1.2,3.6)}{(3,9)}

Factorize the denominator

Scale\ Factor = \frac{(1.2,3.6)}{2.5(1.2,3.6)}

Scale\ Factor = \frac{1}{2.5}

Scale\ Factor = 0.4

<em>Hence, the scale factor used is 0.4</em>

The temperature during a winter day was less than –3 degrees Fahrenheit. Yuri wants to write an inequality for the temperature d
sveticcg [70]
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>
