Answer:$17.50 remaining
Step-by-step explanation: 0.25 x 30 = 7.50
7.50 - 25.00 = $17.50 remaining
Answer:
-28.5
-5
-11.8
-4.5
Step-by-step explanation:
From that data provided for Monday
Temperature at noon = temperature at midnight + the change in temperature
-32 + 20 = -12
Temperature on Tuesday's noon = -17.5 + (-11) = -28.5
Temperature on Friday's noon = -21.8 + 17.3 = -4.5
From that data provided for Monday
Temperature at midnight = temperature at noon - change in temperature
-12 - 20 = -32
Temperature on Wednesday's midnight = 10.5 - 15.5 = -5
From that data provided for Monday,
change in temperature = temperature at noon - temperature at midnight
-32 - (-12) = 20
Change in temperature on Thursday = -24 - (-12.2) = -11.8
Answer:
The cities are approximately 1452 km apart
Step-by-step explanation:
The two cities are on the same Longitude 90°W therefore the distance between them is on a great circle
Latitude of the first city = 23°N
Latitude of the second city = 36° N
Because their latitude are on the same polar axis, we subtract to get the angular difference
Angular Difference = 36 -23 =13°
![Distance= \frac{\alpha}{360} X 2\pi R](https://tex.z-dn.net/?f=Distance%3D%20%5Cfrac%7B%5Calpha%7D%7B360%7D%20X%202%5Cpi%20R)
where ![\alpha = Angular Difference, R= radius of the earth](https://tex.z-dn.net/?f=%5Calpha%20%3D%20Angular%20Difference%2C%20R%3D%20radius%20of%20the%20earth)
![Distance= \frac{13}{360} X 2\pi X 6400=1452.11km](https://tex.z-dn.net/?f=Distance%3D%20%5Cfrac%7B13%7D%7B360%7D%20X%202%5Cpi%20X%206400%3D1452.11km)
The cities are approximately 1452 km apart
ANSWER
The linear equation is: y = 80x + 65
Te cost for 40 football jerseys: $3265
EXPLANATION
Let 'x' be the number of jerseys and 'y' the cost of x jerseys.
Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.
Therefore, the cost 'y' of x jerseys is:
![y=80x+65](https://tex.z-dn.net/?f=y%3D80x%2B65)
Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:
