Answer:
1.5 million
Step-by-step explanation:
To find this you need to find 60% of the 2.5 million people. To do this, multiply 2.5 million by .6, which is 60% in decimal form, and then you'd get 1.5 million.
Red candle:
Initial height = 8 in
Burn rate = 710 in/h
After x hours, the height will be
h₁ = 8 - 710x
Blue candle:
Initial height = 6 in
Burn rate = 15 in/h
After x hours, the height will be
h₂ = 6 - 15x
When the two heights are equal, then
h₁ = h₂
8 - 710x = 6 - 15x
-695x = -2
x = 0.00288 hours
Answer:
The answer may take one of these forms:
0.003 hours, or
0.0029 hours, or
0.00288 hours.
Answer:
Step-by-step explanation:
We can find the derivative using the <u>chain rule.</u>
To get the derivative of an expression with an exponent you multiply the expression by the exponent and raise it to the power of the exponent minus one.
Then multiply it by the derivative of the expression inside the parentheses.
The derivative of 4x+3 is 4, so multiply the rest by 4.
Therefore the derivative is:
Hey there! :)
40 - 24 6/7
Since 24 6/7 is a mixed number, change 40 to a mixed number,
40 = 39 7/7
<em>Now subtract</em>
Whole number: 39 - 24 = 15
Fraction: 7/7 - 6/7 = 1/7
15 + 1/7 = 15 1/7
Your answer is C) 15 1/7
Hope this helps :)
