On a certain hot summer's day, 291 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled $472.50 How many children and how many adults swam at the public pool that day?
Answer: 219 children and 72 adults swam at the public pool that day.
Step-by-step explanation:
Let x = Number of children , y= Number of adults.
As per given, x+y = 291 (i)
1.5x+2y = 472.50 (ii)
Multiply 2 on both sides of (i) , we get
2x+2y = 582 (iii)
Eliminate (ii) from (iii), we get
0.5x = 109.5
[tex]\Rightarrow x=\dfrac{109.50}{0.5}=219[/tex]
Put value of x= 219 in (i)
219+y= 291
⇒ y = 291-219 = 72
Hence, 219 children and 72 adults swam at the public pool that day.

Derek is selecting a sock from his drawer .He chooses a sock at random and then selects a second sock at random .what is the probability that Derek selected a striped sock both times
Answer: 1/15
Step-by-step explanation:
The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.
If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.
The probability that Derek selected a striped sock both times will be:
= 2/6 × 1/5.
= 2/30
= 1/15
A farm raises cows and chickens. The farmer has a total of 46 animals. One day he counts the legs of all his animals and realizes he has a total of 156 legs. How many chickens does the farmer have?
Answer:
32 chickens
Step-by-step explanation:
Let
The number of cows = x
The number of chickens = y
A farm raises cows and chickens. The farmer has a total of 46 animals.
x + y= 46..... Equation 1
x = 46 - y
Number of legs of chickens = 2
Number of legs of cows = 4
One day he counts the legs of all his animals and realizes he has a total of 156 legs.
Hence:
2x + 4y = 156.... Equation 2
We substitute 46 - y for x in Equation 2
2(46 - y) + 4y = 156
92 - 2y + 4y = 156
- 2y + 4y = 156 - 92
2y = 64
y = 64/2
y = 32
Solving for x
x = 46 - y
x = 46 - 32
x = 14
The number of cows = x = 14 cows
The number of chickens = y = 32 chickens
Therefore, the number of chickens that the farmer has is 32 chickens

A train at a constant speed and goes 7.5 kilometers in 6 minutes. At the rate:
How far does the train go in 1 minute?
How far does the train go in 100 minutes?
Answer:
The distance covered by a train in 1 minute = 1.25 kilometers
The distance covered by a train in 100 minutes = 125 kilometers
Step-by-step explanation:
The distance covered = 7.5 kilometers
Time taken = 6 minutes
Calculating unit rate
unit rate = 7.5 kilometers / 6 minutes
= 1.25 kilometers per minute
Thus,
The distance covered by a train in 1 minute = 1.25 kilometers
and
The distance covered by a train in 100 minutes = 1.25 × 100
= 125 kilometers

64
Answer:
x = 8
Step-by-step explanation:
You know that 7x - 4 and 5x + 12 are equal, so you can set up an equation and solve it:
[tex]7x - 5 = 5x + 12[/tex]
subtract 5x from both sides
[tex]2x-4=12[/tex]
Add 4 to both sides
[tex]2x = 16[/tex]
divide both sides by 2
[tex]x = 8[/tex]
Answer:
7x - 4......1

PLEASE PLEASE HELP I AM TIMED! What is the domain and range of the function?
Answer:
Domain is; d is a set of non - zero integers.
Range will be p(d) for values of; d > 0 or d < 0
Step-by-step explanation:
In Mathematics, the domain is the set of all input values in a given function while range is the set of output values for each given input function.
Thus, looking at the function given;
p(d) = -(28.2/d) + 0.859
It is clear that if d = 0, we will have an undefined solution as any number divided by zero is undefined.
Thus, the domain is; d is a set of non - zero integers.
Range will be p(d) for values of; 0 < d < 0
Matt decided to go out to eat. He ordered a soda for $2.15, some chicken for $8.77 and a slice of cake for $4.10. What would his entire bill be if he tipped his waiter 18%?
Answer: $ 17.72
Step-by-step explanation:
Cost of soda = $2.15 , Cost of chicken = $8.77 , Cost of slice of cake = $4.10.
Total bill amount = (Cost of soda ) + (Cost of chicken) +(Cost of slice of cake)
= $ (2.15 + 8.77 +4.10)
= $ 15.02
Tip amount = 18% of Total bill amount
= 0.18 (15.02)
= $ 2.7036 ≈ $2.70
Entire bill = Total bill amount + Tip amount
= $ ( 15.02+2.70)
= $ 17.72
Hence, entire bill = $ 17.72
