Ben and his friends are going to play putt- putt. At one location, they can pay $2.00 for rentals plus $7.50 per game. At another location, it would cost $8.00 for rentals plus $6.00 per game. How many games would they have to play for either location to cost the same amount?
Answer:
4 Games
Step-by-step explanation:
Let x be the no. of games played in order to cost the same amount
At one location, they can pay $2.00 for rentals plus $7.50 per game.
So, Total cost at this location for x games = 2+7.5x
At another location, it would cost $8.00 for rentals and $6.00 per game
So, Total cost at this location for x games = 8+6x

Barry is given 0.4 and 0.9 cents
He already has 6.30 in his bank
0.4+0.9 = 1.3
add the money he was given to the bank
1.3 + 6.3 = $7.60
Barry has $7.60 in total.
2. $3.70Henry buys two candy bars, one is worth 3.20 and the other is 1.60
add them up to get the total
3.20 + 1.60 = 4.80
Henry has $8.50
subtract the cost of the chocolate from the money he has
8.50 - 4.80 = $3.70
Henry has $3.70 left over from the $8.50
3. $7.20Beth buys a bouncy ball worth 1.20 and pen that is 5 times that amount.
this put into an equation is
1.20 + (5*1.20) =
1.20 + 6 =
the answer to this equation is
$7.20
The bouncy ball and pen cost $7.20 in total.
4. $9.20Joe found 1 dollar ($1), 4 quarters ($1), and 3 dimes ($0.30) on Monday
In total that is,
1 + 1 + 0.30 = $2.30
He found $2.30 on monday
On tuesday, he finds 3 times that amount
3 * 2.30 = $6.90
He found $6.90 on tuesday
add them up and you get
2.30 + 6.90 =
$9.20
Joe found $9.20 on Monday and Tuesday combined.
Answer:
1. $7.60
2. $3.70
3. $7.20
4. $5.20
Step-by-step explanation:
1. 0.40+0.90+6.30= 7.60
2. 8.50-(3.20+1.60)=3.70
3. 1.20+(1.20*5)= 7.20
4. (1+1+0.30)+(1+1+0.30*3)= 5.20
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
Find the perimeter of this shape.
Answer:
draw a line that makes a triangle and rectangle.
hypotenuse= 30
3k-4k-5k triangle
18-24-30
so the short part of triangle is 18 cm
10+10+18+24+30 equals 92
sorry for language I am not familiar with English
the perimeter of this shape is
24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Stefani slices a right rectangular pyramid with a plane and the cross-section is in the shape of a trapezoid. How does Stefani slice the pyramid?
Please HELP
Answer:
Perpendicular to the base but not through vertex
Step-by-step explanation:
This happens because when u slice from a side, you see the 2 slanted sides and the base, but you also see the top of the trapezoid because it is not cutting through the absolute vertex. This happens because it is slanted.

You randomly choose one of the tiles and flip the coin. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
8 tiles
Answer:
Step-by-step explanation:
3/7 x 1/6 = 1/14 is the probability of choosing an odd and then the 20
3 ways to get odd out of 7 possibilities. 1 way to get 20 out of 6 remaining tiles.
Multiply the probabilities to get the compound probability.
Or if you wanted 20 and then an odd, it's
1/7 x 3/6 which also = 1/14

Answer: The ratio is 18:3
Step-by-step explanation:
Answer: 6 to 1
Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.
A video game is on sale at Amazon for 35% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They will have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.
Pat takes 35% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.
Henri finds 65% of the original price and then calculates 110% of the sale price.
Will Pat's strategy calculate the correct total? Explain the calculations.
Will Henri's strategy calculate the correct total? Explain the calculations.
Do they each have enough to purchase the game?
Explain your answers using complete sentences and show your work.
Answer:
yes pat will, because he is taking 35% off of the original price to get the sales price. no henry wont, because the total is supposed to go down not up. no they will not be able to buy 1 for each of them because 1 game costs $18.70
Step-by-step explanation:
28.50/100=0.285
0.285=0.28
0.28*35=9.80
28.50-9.80=18.70
