Answer:
<h2>A. 11</h2><h2 />
Step-by-step explanation:
30-2(7+2)-1
= 30 - 2(9) - 1
= 30 - 18 - 1
= 11
Answer:
A) y = 8.63 x
B) $224.38
Step-by-step explanation:
The the average monthly cost = (147.98+152.17+165.63)/3 = $155.26
So, For 18 employees the average monthly cost = $155.26
Let the equation that can be used to estimate y, the average monthly cost, in dollars, to buy lunch for x employees. ⇒ y = mx
For x = 18 , y = $155.26
So, m = y/x = $155.26/18 ≈ $8.63
∴ y = 8.63 x
To find the total cost for 26 employees.
∴ x = 26
∴ y = 8.63 * 26 = 224.38
The total cost of a monthly lunch for 26 employees = $224.38
Answer:
D) Count the number of beats for one minute
Step-by-step explanation:
When measuring a person's pulse, we are measuring their heart beat. A person's pulse is measured using beats per minute (BPM).
Though not as accurate, most medical personnel simply counts the beats per 10 seconds, and then multiply by 6
For instance:
10 seconds = 13 beats
13 x 6 = 78 bpm
In conclusion, a person's pulse is based on how many beats per minute!
Hope this helps! :)

find the smallest and largest squares
oh, nevermind an easier way
square root them
4 million=4,000,000
square root=2000
9million=9,000,000
square root=3000
how many numbers betwee 2000 and 3000?
3000-2000=1000
minus 1 because of math
999 numbers fit the criteria
Set up a proportion. (y-1)/6 = 5/3 then cross multiply to get 30 = 3y-3. add three and then divide by three to get y= 11. do the same process for X.
