Answer:
a) T= 0.25 C+37
b) T= 62°F
Step-by-step explanation:
Here T is a linear function of C
T= mC+b
For each additional chirp C corresponding to an increase in T of 0.25
therefore, m= 0.25
T= 42° F C=20 ( given)
therefore,
a) 42= 0.25×20+b
b= 37
therefore T= 0.25 C+37
b) now C= 100
therefore, T= 0.25×100+37 = 62°F
Answer:
a. 180 - 90 + 65
180 - 155 = 25 degrees
b. 5^2 + 6^2 = 61
61
: 7^2 = 49 close enough 8^2 = 64 too much. 7 is your answer.
c. 100 divided by 0.10 = 1000
Answer:
y=7/6x
Step-by-step explanation:
When given an equation and asked to find the equation of a perpendicular line that intersects it, you know that the slope is the slope of the equation is the negative recipricoal of the given equation. i.e. y=2x+2 and y=-1/2x+2. The y-intercept does not matter.
I hope you understood and that this helps!
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
Answer:
The probability of getting gray = no. of gray shades / total
=> 2/7
The probability of getting head when we toss a penny = head / total ( head + tail )
=> 1/2
