3/7. if you make them equivalent fractions it would be 30/70 or 14/70. 30/70 is bigger.
Answer:
The answer would be A
Step-by-step explanation:
a. the pumpkins maximum height is 204.06 feet and it hits the ground after 7.01 seconds.
20/5
4x/x adding 10 to each
4x+10/x+10 =2
Multiple x+10 to each side
4x+10=2x+20
Then subtract and get
2x=10
Divide
X=5
Now plug it back in
20/5
Answer:
90 degrees
Step-by-step explanation:
Complete question
A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee
The initial temperature occurs at x = 0
Substitute x = 0 into the expression;
T=70(0.80)^x+20
T =70(0.80)^0+20
Since any value raise to power of zero is 1, hence;
T = 70(1)+20
T = 70+20
T = 90 degree Celsius
Hence the initial temperature of the coffee is 90 degrees
