Answer:
60, and m = 30, and 1 min 20.
Step-by-step explanation:
For A, the 60 is the starting point meaning that the temperature was intitally 60 degrees
For B, if we divided both sides by 2 we get the answer m = 30, meaning every minute, it was up 30 degrees.
For C, we know that in one minute it will be 90 degrees, so 60 seconds = 30 degrees. So lets divided both sides by 3 to get 10 degrees. We get 20 seconds. It will take 1 min and 20 for it to be 100 degrees.
Hopefully thats right.
Answer: B. Graffiti
Step-by-step explanation:
Diagonal length is a line from a left corner to a right in a rectangle or square.
Basically making two triangles.
You use the equation a^2+b^2=c^2
So 45.25^2+25.5^2=x^2
2,047.5625+650.25=x^2
2,697.8125=x^2
Then square root them both
51.9404707=x
And when rounding to the nearest number the diagonal length is 52 inches
0.7 or 7/10. If the hundreths place is less than 5 you keep the tenths place as it is. If it is 5 or greater you round up and have the tenths place be one number higher. In this case you keep .7 because the hundreths place is lower than 5. Hoped this helped!
