Answer: The bench is $150 and the garden table is $300
Answer:120 animals are in the pet store
Step-by-step explanation:
<u>Answer</u> : The demonstration is below :)
Step-by-step explanation :
<u>We use Pythagoras' </u><u>theorem </u><u>:</u>
- In the triangle ABC we have :
AB² = AC² - BC² = 15² - 9² = 144 = 12²
- In the triangle ABD we have :
DB² = AD² - AB² = 13² - 12² = 5²
cos(a) = BD/AD = 5/13
Answer:
theta =36.45268177
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos theta = 74/92
Taking the inverse cos of each side
cos^-1 ( cos theta) = cos^-1 (74/92)
theta =36.45268177
Answer: 90
Step-by-step explanation: The mean of a data set is equal to the
sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set
shown here, begin by adding the numbers.
Adding the numbers, we get 720.
This will be divided by the number of numbers in the set, or 8.
So we have 720/8 or 90.
So the mean of the data set shown here is 90.
