Answer:
(a)
Amount of water in the first pool (in liters) = 3850 liters - 33 liters per minute * x minutes
Amount of water in the second pool (in liters) = 4370 liters - 43 liters per minute * x minutes
(b)
3850 liters - 33 liters per minute * x minutes= 4370 liters - 43 liters per minute * x minutes
Step-by-step explanation:
(a) With x being the minutes after which you want to calculate the amount of water in the pool, to calculate this amount of water you must subtract the water drained from the initial amount of water that the pool contains.
Knowing that, for example, the water from the first pool drains at a rate of 33 liters per minute, then after x minutes, the total water drained will be 33 liters per minute * x minutes. Then:
Amount of water in the first pool (in liters) = 3850 liters - 33 liters per minute * x minutes
Reasoning in the same way:
Amount of water in the second pool (in liters) = 4370 liters - 43 liters per minute * x minutes
(b) Now want to know when the two pools would have the same amount of water. If they have the same amount of water then you can express:
Amount of water in the first pool = Amount of water in the second pool
Replacing the expressions found in (a):
3850 liters - 33 liters per minute * x minutes= 4370 liters - 43 liters per minute * x minutes

Lin and her brother each created a scale drawling of their backyard, but a different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard Express the Lin's scale for the drawling without units. Type your answer in the format: 3:4 With no spaces
Answer:
1:12
Step-by-step explanation:
Give the following :
Lin's scale = 1 inch to 1 foot
Brother's scale = 1 inch to 1 yard
Lin's scale for the drawing without units :
To obtain this, convert foot to inch:
1 foot = 12 inches
Hence,
1 inch is equivalent to 12 inches
Hence, rewriting Lin's scale without units :
1:12

POSSIBLE POINTS. 7 Two clothing stores are having a sale on all their dress shirts. Store A is charging $15 for each dress shirt. Store B is $18 for each shirt but giving customers a coupon for a $9 discount when they check out. Which of the following statements are true? There can be more than one correct answer.
Answer:
The statements are not provided, so i will answer in a general way.
Let's define the variable x as the number of dress shirts brought for some person.
In store A, each one costs $15.
Then the cost of x dress shirts will be:
A(x) = $15*x.
In store B, each one costs $18, but there is a coupon of $9, then we can write the cost in store B as:
B(x) = $18*x - $9.
Now we can find wich store will be cheaper for a given number x, by calculating the difference between A(x) and B(x).
D = A(x) - B(x)
If D is positive, means that B(x) is cheaper.
If D is negative, means that A(x) is cheaper.
If D is equal to zero, means that the cost is the same in both stores.
D = A(x) - B(x) = $15*x - $18*x + $9 = (-$3*x) + $9.
First, let's find for what value of x we have the same cost in both stores:
0 = (-$3*x) + $9.
$9/$3 = 3 = x.
Then for 3 dress shirts, the cost will be the same in each store.
Now, as the coefficient that multiplies x is negative, if we have x > 3, then D will be negative, and if x < 3, D will be positive.
then:
For x = 3, the cost is the same in both stores.
for x > 3, Store A is cheaper.
For x < 2, Store B is cheaper.
