Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour

Answer: £66</h3>
Your teacher may want you to leave off the pounds sign.
==========================================================
Explanation:
x = amount Bill gets
3x = amount Sam gets, because he gets three times as much
x+3x = 4x = total amount of money
4x = 88
x = 88/4
x = 22
Bill gets £22
3x = 3*22 = 66
Sam gets £66
Note that 22+66 = 88 to help confirm the answer.
Answer:
Diameter = 7
Radius = 3.5
Step-by-step explanation:
Hi! Ace here.
So, the formula to find circumference is dπ or 2rπ
So to find the diameter, you do the circumference/π
To find the radius, you'd do the circumference/2π
Plug-in those numbers and there you go!
Hope this helps, let me know if you have any questions.
I know this was a very vague explanation so I encourage you to ask any questions. Thank you!
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
512.50/125%=410
100% is the dealers cost
25% is the markup
$410 is the dealer's price before markup
410×25%=102.5. 410+102.5=512.5
