Add the total bills:
23.59 + 40.65 + 30.50 + 15.68 = 110.42
Divide his tips by the total bills to get the rate of the tips
17.67 ÷ 110.42 = 0.16
0.16 x 100% = 16%
His tips were 16% of the bills.
To check:
23.59 x 16% = 3.7744
40.65 x 16% = 6.504
30.50 x 16% = 4.88
15.68 x 16% = <u>2.5088</u>
total tips 17.6672 rounded off to 17.67
0.05/1 min * 60 min = 0.05 * 60 = 3
<em>Therefore, the unit rate per hour is $3.</em>
We can figure out how many times a heart beats in one minute (so we can figure out how many minutes it will take for 140 times) by dividing 700 by 10. This gives us 70. Now we know that a heart beats 70 times each minute. Now we know it would take 2 minutes for a heart to beat 140 times because 70×2=140.
Two minutes is the answer.
Answer:
Not an exponential function. The exponent is a constant.
Step-by-step explanation:
An exponential function has the variable in the exponent. This function raises the variable to a fixed power, so it is not an exponential function.
Answer:
The statement is False.
Step-by-step explanation:
Consider the provided information.
If a linear system has four equations and seven variables, then it must have infinitely many solutions.
We need to determine the above statement is true or false.
The above statement is false, it could be inconsistent, and therefore have no solutions,
For example:
Hence, there is no solution.
