9am to 4 pm is 7 hour and you use the total cost divid by hours you can get you answer which is 4.12 per hour
Answer:
71.63 kilowatts hours
Step-by-step explanation:
We are told in the question:
John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour.
We are to find, How many kilowatt hours can he use and keep his monthly cost no more than $109.
Step 1
$109 - $20.90
= $88.1
$88.1 is the amount left to spend on killowatts of electricity per hour after removing the normal monthly electricity bill in a month
Step 2
$1.23 = 1kilowatts per hour
$88.1 = y kilowatts per hour
Cross Multiply
= $1.23 × y kilowatts per hour = $88.1 × 1 kilowatts per hour
y kilowatts per hour = $88.1 × 1 kilowatts per hour/ $1.23
= 71.62601626kilowatts hour.
Approximately = 71.63 kilowatts hour
Therefore, John can use 71.63 kilowatts per hour and keep his monthly cost no more than $109
To find the answer for x, you have to use the pythagoryen theorem. The line AC is 16 inches, but the little segment of the triangle is 4 inches. So first, you have to use the pythaoryen theorem and get this equation: CB plus AB=16 inches. Once you find CB, use it again to find the value of DB. DB plus DC equals CB. Then DB = X.
