The morning low tide at the beach is 12 inches. After 6 hours, the afternoon high tide is 57 inches. What is the average number of inches the tide changed per hour?
Answer:
7.5 inches per hour
Step-by-step explanation:
Given that:
Morning low tide at beach = 12 inches
Afternoon tide after 6 hours = 57 inches
Average number of inches tide changed per hour :
(Afternoon tide - morning tide) / number of hours
(57 inches - 12 inches) / 6 hours
45 inches / 6 hours
= 7.5 inches per hour

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement
Answer:
r+c=80
.50r+.10c=20
Step-by-step explanation:
each rose costs $0.50
each carnation costs $0.10
The number of roses is r, and the number of carnations is c.
the arrangement has a total of 80 flowers, so we have that:
r + c = 80
the cost is $20, so we have:
r*0.5 + c*0.1 = 20
so our system of equations is:
r + c = 80
r*0.5 + c*0.1 = 20
and we can also solve it; for this isolate one of the variables in the first equation:
r = 80 - c
now let'r replace this in the second equation:
(80 - c)*0.5 +c*0.1 = 20
40 - c*0.4 = 20
c = 20/0.4 = 50
this means that we have 50 carnations, and the other 30 are roses.

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Noon (+3)
-2°C
4pm (+?)
0°C
Equation I used:
(-5) + (3) + x = 0
I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)
What is the correct answer for both?
Answer:
14) C (-2, 4)
15) D (-3, -3)
Step-by-step explanation:
-6x + 4y = 28
6x + 9y = 24
-6x + 4y = 28
4y = 28 + 6x
y = 7 + 1.5x
6x + 9y = 24
6x + 9(7 + 1.5x) = 24
6x + 63 + 13.5x = 24
19.5x + 63 = 24
19.5x = -39
x = -2
-6x + 4y = 28
-6(-2) + 4y = 28
12 + 4y = 28
4y = 16
y = 4
____________
4x - 4y = 0
-4x + 3y = 3
4x - 4y = 0
4x = 4y
x = y
-4x + 3y = 3
-4(y) + 3y = 3
-4y + 3y = 3
-1y = 3
y = -3
4x - 4y = 0
4x - 4(-3) = 0
4x + 12 = 0
4x = -12
x = -3

The sales tax rate Atlanta's hometown is 7%. If she buys 3 lamps for 23.50 each and a sofa for $770, how much sales tax does she owe?
Answer:
35
Step-by-step explanation:
Will runs a business that employs 105 staff.
Each member of staff works 35 hours a week and gets an hourly wage of £7.60
The staff have complained that they are not being paid enough and have asked
for a 10% pay rise.
How much will the proposed pay rise cost Will on a weekly basis?
£
Each employee makes 35 x 7.60 = 266 per week.
105 employees x 266 = 27,930 per week total pay.
27930 x 10 % = 27930 x 0.10 = 2,793 more per week.

Answer:
the answer to x is 111
Step-by-step explanation:
A+B=X
Since its extended you add the two legs together
Hope this helps!
Answer:
111 degrees
Step-by-step explanation:
Angles in a triangle add up to 180 degrees, so we do 180-36-75 to find out the missing angle (=69). Then, angles on a straight line add up to 180 degrees too, so we do 180-69=111 degrees. :)
