A football stadium splits ticket sales in ratio of 3 : 4 between the away team and the home team. The home team make £36,000. Wh
Naddika [18.5K]
<h3>Answer is 63,000 pounds</h3>

The ratio 3:4 means for every 3 pounds made in away team tickets versus home team tickets. Multiply both sides by 9000 to have that 4 turn into 36000. The ratio 3:4 will then turn into 27000:36000

With this new ratio, we see that the away team pulls in 27000 and the home team pulls in 36000. Add the two amounts to get the final answer

27000+36000 = 63000

------------

We could alternatively add 3 and 4 (from the ratio 3:4) to get 3+4 = 7. Then multiply by that same scale factor 9000 getting 9000*7 = 63000.

The temperature is 2 degrees and drops to -15 degrees overnight. Write and then evaluate a subtraction expression to determine t
KiRa [710]

Answer:

-17 degrees

Step-by-step explanation:

Given that:

Initial temperature = 2 degrees

Final temperature = -15 degrees

To Determine:

The change in temperature.

Solution:

First of all, let us have a look at the method for calculating the change in any quantity.

Let the initial quantity = a

Let the final quantity = b

Change in quantity = Final quantity - Initial quantity = b - a

Here, we are given the quantity as temperature.

where a = 2 degrees and

b = -15 degrees

Therefore, the change in temperature = -15 - 2 = \bold{-17} <em>degrees</em>

What is 3/4 - 1/2?...Please explain...Rewarding Brainliest...
PSYCHO15rus [73]

Answer:

1/4

Step-by-step explanation:

Find common denominators. Note that what you multiply (or divide) from the denominator, you must also do the same to the numerator.

In this case, the common denominator would be 4. Multiply 2 to both the numerator & denominator of (-1/2):

(-1/2) * (2/2) = (-1 * 2)/(2 * 2) = -2/4

Subtract across:

3/4 - 2/4 = (3 - 2)/4 = 1/4

1/4 is your answer.
