Answer:
$8.00
Step-by-step explanation:
Let's set up the equation first.
What do we know:
1. We have 6 friends spliting the costs of the gifts
2. After purchasing the gifts they have $42 in change
3. They originally had $90 to spend.
Equation:
6f + $42 = $90
Next: Subtract the $42 from each side and we are left with:
6f = $48
Divide both sides by 6 and we are left with
f = $8
Since f represented the cost each friend spent our answer is $8.00
Each friend will pay $8.
What are the fundamental mathematical operations?The Fundamental mathematical operation are Addition,Subtraction
Multiplication and Division.
Given,
Six friends will equally share the cost.
they paid $90 and received $42 in change.
The money they will pay = $90 -$42
= $48.
As they will equally share the cost.
the individual cost will be = $48/6
=$8.
Therefore, Each friend will pay $8.

The game room of the youth center needs carpet. The room measures 3 feet by 2 feet on the blue print. If the scale on the blue print 1 foot to 5 yards,what is the actual length of the game room?
Answer:
The actual room measurement is 15 yrds by 10 yrds
Then the length is 15 yrds
Step-by-step explanation:
1 feet is equal to 0.3333 yards
The room measure 3 by 2 feet
Scale on blue print 1 ft to 5 yrds.
That's is to say for every ft in the Blue print...it is 5 yrds real.
So it's multipling factor bis five.
The actual measurement will be
5*(3 by 2) yrds
The actual measurement is 15 yrds by 10 yrds .

Joey chestnut is trying to break his own world record for eating the most hot dogs and buns in 10 minutes. He needs to eat more than 72 hot dogs to break his record. After 1 minutes of competition, Joey has eaten 10 hot dogs. Joey wants to know the number of hot dogs per minute that he need to eat for the next 9 minutes to break his own record.
Answer:
Joey needs to eat 7 hot dogs per minute to break his own record in next 9 minutes.
Step-by-step explanation:
Joey needs more than 72 hot dogs in 10 minutes to break his own record.That means Joey needs to eat at least 73 hot dogs in 10 minutes.
After 1 minute Joey has eaten = 10 hot dogs.
In remaining 9 minutes balance hot dogs = 73-10 =63
Therefore per minute hot dogs to be eaten = 63/9 =7
So answer is 7 hot dogs per minute to be eaten.
Joey needs to eat 7.00 hot dogs per minute for the next 9 minutes to break his own record.
To break his record, Joey Chestnut needs to eat more than 72 hot dogs in 10 minutes. After the first minute, he has already eaten 10 hot dogs. So, he has 9 minutes left to eat the remaining hot dogs needed to break the record, which is 72 - 10 = 62 hot dogs.
To find out how many hot dogs per minute Joey needs to eat for the next 9 minutes, we divide the remaining number of hot dogs by the remaining time:
Hot dogs per minute = Remaining hot dogs / Remaining time
Hot dogs per minute = 62 hot dogs / 9 minutes
Hot dogs per minute ≈ 6.89 hot dogs per minute
Therefore, Joey needs to eat 7.00 hot dogs per minute for the next 9 minutes to break his own record.
It's important to note that Joey needs to eat more than this calculated rate per minute to ensure he breaks his record, as he cannot consume a fraction of a hot dog. So, he should aim to eat at least 7 hot dogs per minute to secure his victory.

Ryan has three sticks of lengths 6 inches, 10 inches, and 8 inches. He wants to join the three sticks to form a right triangular base for a model. Discuss whether these sticks form a right triangle. EXPLAIN
Answer:
yes
Step-by-step explanation:
for the sticks to form a right triangle, the 3 sticks' lengths must comply w the Pythagoras theorem: hypothesis^2 = first side^2 + second side^2
hypothesis is the longest length so its 10
10^2 = 100 = 36 + 64 = 6^2 + 8^2
so the 3 sticks will form a right triangle
Answer:
6^2+8^2=10^2 so yes
Step-by-step explanation:
In order to test a triangle with lengths 6, 8 and 10 inches is right-angle or not, the Pythagoras equation should be used: a^2+b^2=c^2.
As 6^2+8^2=10^2 so yes, the three sticks will form a right-angle triangle.

Mr lee owns a toy store. He orders 20 toys consisting of airplanes, cars, and trains. The number of airplanes is 2/3 the number of cars. The number of cars is 3/5 the number of trains. The price of each toy airplane is $12 and the price of each toy car is $8. Each toy train costs 1/2 as much as the toy airplane. How many toy cars does he buy? How much does Mr lee spend for the toys?
Answer:
Toy Cars=6 and total spending by Mr.Lee=$156
Step-by-step explanation:
Let us first consider
Number of Airplanes=A Cars=C and Trains=T
Now how to start with the problem ? Just start reading it step by step. First statements says that The number of airplanes is 2/3 of The number of cars.
Now how to convert it into an mathematical expression?
here the word "=" is of most important, The number of airplanes "is" whenever you encountered "is" just place a "="
so the first statement can be converted into mathematical expression as,
A=2/3*C (The number of airplanes is 2/3 of The number of cars.)
Now as per the second condition we can write it in mathematical form as,
C=3/5*T (The number of cars is 3/5 the number of trains).
and the third condition as,
C=3/5*T (The number of cars is 3/5 the number of trains).
Now , we have expressed the statements in mathematical expressions. we have three expressions.
Now It is also given that total number of Toys=20 so we can write it as,
A+C+T=20. ............(1)
Till now we have expressed everything in the question in mathematical form.
now for solving such type of question we need to express the expression giving total in a single entity, expressed it in terms of Airplanes,Cars or Trains,
here we are expressing it in terms of Cars so we can rewrite it (1) as,
2/3*C+C+5/3*C=20 (A=2/3*C and C=3/5*T so T=5/3*C)
by solving this we will get C=6
Total number of car toys, answer of first part
now put this value of C in expression 1,
2/3*C+C+T=20
so the value of T will be 10. T=10
and the total is toys are 20 so 20-10+6=4
Means Airplanes are 4.
Now the cost for each toy is.
A=$12,C=$8 and T=1/2 A i.e T=$6.
So the total cost would be,
4*12+6*8+10*6=$156
$156 answer of second part
I Hope this will help you to solve such kind of Problems.
Mr. Lee buys 6 toy cars for his store. The total cost for all the toys he purchased is $156. This includes the cost of toy airplanes, cars, and trains, with each toy tailoring a specific price.
The student wants to know how many toy cars Mr. Lee bought and the total cost of all toys he purchased for his store. We start with the relationships provided: the number of airplanes is 2/3 the number of cars, and the number of cars is 3/5 the number of trains. We also know that the total number of toys is 20. Let A be the number of airplanes, C be the number of cars, and T be the number of trains. So, we have A = (2/3)C and C = (3/5)T.
From these ratios, we can express airplanes and trains in terms of cars: A = (2/3)C, T = (5/3)C. The equation A + C + T = 20 becomes (2/3)C + C + (5/3)C = 20. Simplifying this, we get (10/3)C = 20, so C = 6. Thus, Mr. Lee buys 6 cars. The number of airplanes, A = (2/3) * 6 = 4, and the number of trains, T = 20 - A - C = 20 - 4 - 6 = 10.
Now let's calculate the total cost. Each toy airplane costs $12, each toy car costs $8, and each toy train costs half as much as an airplane, which is $6. The total cost is 4 airplanes * $12 + 6 cars * $8 + 10 trains * $6, which equals $48 + $48 + $60, resulting in a total of $156 spent by Mr. Lee.

Line j and Line k are parallel lines that have been translated. The resulting images are show as j' and k'. How can you describe j' and k'? A) Skew lines B) Parallel lines C) Horizontal lines D) Intersecting lines
The lines j' and k' are parallel lines.
Option: B is the correct answer.
Step-by-step explanation:We are given Line j ans Line k such that both are parallel to each other.
Now as we know that the translation transformation just change the position of the location but does not changes it shape.
As both the lines were parallel to each other so on translating both of them they just shifted some units to the right but the behavior remains the same.
Also, from the figure attached to the answer we may observe that the two lines are parallel to each other as the distance between the two lines at each point is constant.
Hence, the correct answer is:
Option: B

A museum gift shop manager wants to put 1,578 polished rocks into small bags to sell as souvenirs.If the shop manager wants to put 15 rock in each bag,how many complete bags can be filled?How many rocks will be left over
The number of bags that can be filled completely is 105 and the 3 rocks will be left over.
What is division?Division is the process of dividing a number by a given number.
Given that, the number of rocks is 1578 and the number of rocks in each bag is 15.
To find the number of bags, divide the number of total rocks by the number of total rocks in each bag:
1578/15
= 105.2
≈ 105
Now, the number of rocks in 105 bags is:
105 ×15
= 1575
So, the number of rocks left is:
1578 - 1575
= 3
Hence, the number of bags that can be filled completely is 105 and the 3 rocks will be left over.
