I believe the answer is 2.7 but I'm not sure...
A ratio is comparison between two number such as
I have three dogs and two cats the ratio of cats to dogs is 2:3 or what is the ratio of cats to total pets which is 2;5
Answer:
75 gallons
Step-by-step explanation:
50+(50/2)=
50+25= 75
(1/2 of 50 is 25)
Answer:
400 pounds
Step-by-step explanation:
Question: 80 is 20% of what?
Formula = a = p* w
w (whole) = a/p
a/p = 80/0.20 (decimal form of 20%)
The initial weight was 400 pounds. It should be the answer so I hope this helps.
Answer:
a) 
b) 
Step-by-step explanation:
We know that theres a <u><em>linear relationship</em></u> between the rate of the chirping of crickets and the air temperature.
<u><em>The equation of a line is</em></u>:

So, let's name our variables
x= Temperature
y=Rate of the chirping
First of all, we need to find the <u><em>slope</em></u> with the two given points
60ºF , 
80ºF, 
By,


<u>Now, the </u><em><u>equation</u></em><u> between the air temperature and the number of chirps is:</u>


Solving for y,
a) 
b) <u>To calculate the </u><u>rate</u><u> at which the crickets chirp when the </u><u>temperature is 102 ºF</u><u> we need to evaluate y(102)</u>
