Answer:
The club has 56 members
Step-by-step explanation:
We can set up a ratio problem to find the total number of kids in the club. There are two ways to do this, and I will show you both. The first way is to immediately set up a ratio between the number of boys and the number of total members in the club. Since the ratio of girls to boys is 6:2, the ratio of boys to members is 2:8 (add the number of girls and boys in the ratio to get the total number of people). Now, we can set up an equation, letting x equal the number of members total, and solve using cross multiplication:
[tex]\frac{2}{8}=\frac{14}{x}\\\\ 112=2x\\\\ x=56[/tex]
The other way to solve this problem would be to figure out the number of girls in the club if there are 14 boys and then add the two quantities together. If we let y be the number of girls in the club, we get the following solution:
[tex]\frac{6}{2}=\frac{y}{14}\\\\ 2y=84\\\\ y=42\\\\x+y=56[/tex]
Either way, we get that the total number of members is 56
Bob can chop down 10 trees in 30 minutes, while Frank can chop down 15 trees in 30 minutes. Working together, how long will it take them to chop down 100 trees
It will take 120 minutes to chop down 100 trees.
Bob chops 10 trees in 30 minutes, so he can chop 100 trees in 300 minutes.
Frank chops 15 trees in 30 minutes, so he can chop 100 trees in 200 minutes.
Solve this using the following equation:
15 / 30 = 100 / x
Solving for x gives 120 minutes.

Step-by-step explanation:
A grocery store is offering a sale on bread and soup. Khalil buys four cans of soup and loaves of bread for $11.67. Ronda buys eight cans of soup and one loaf of bread for $12.89.
a) rite equations for both Khalil's and Ronda's purchases.
b)solve the system to find the price of one can of soup and the price of one loaf of bread.
please help :((
Answer:
a. The equation should be
4x + 3y = $11.67
8x + y = $12.89
b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09
The calculation is as follows:
here we assume the soup be x and bread be y
So, the equations are
4x + 3y = $11.67 .........(1)
8x + y = $12.89.........(2)
Here we need to multiply by 2 in equation 1
8x + 6x = $23.34
8x + y = $12.89
5y = $10.45
y = $2.09
Now x should be
8($2.09) + y = $12.89
x = $1.355
Hope this helps :)
Answer:
A)
Khalil: 4s + 1b = 11.67
Ronda: 8s + 1b = 12.89
B)
Can of soup = $0.305
Loaf of Bread = $10.45
(Please mark brainliest)
Step-by-step explanation:
Make s a can of soup
Make b a loaf of bread
A)
Khalil: 4s + 1b = 11.67
Ronda: 8s + 1b = 12.89
B)
12.89 - 11.67 = 1.22
1.22 / 4 = 0.305
11.67 - 1.22 = 10.45
Can of soup = $0.305
Loaf of Bread = $10.45

Audrey is driving to a concert and needs to pay for parking. There is an automatic fee of $6 just to enter the parking lot, and when she leaves the lot, she will have to pay an additional $2 for every hour she had her car in the lot. How much total money would Audrey have to pay for parking if she left her car in the lot for 5 hours? How much would Audrey have to pay if she left her car in the lot for tt hours?
Answer:
a. $16
b. $26
Step-by-step explanation:
a. 6+2(5)= 16
b. im assuming tt means ten 6+2(10)=26
If Audrey leaves her car in the lot for "t" hours, she would have to pay a total of $6 + $2t for parking.
If Audrey leaves her car in the parking lot for 5 hours, she will have to pay the initial fee of $6 plus $2 for each hour she parked. For 5 hours, she will pay:
Initial fee: $6
Additional fee for 5 hours: $2 * 5 = $10
Total parking cost: $6 + $10 = $16
If Audrey leaves her car in the parking lot for "t" hours, the total parking cost can be calculated as:
Total parking cost = Initial fee + Additional fee for "t" hours
Total parking cost = $6 + $2t
So, if Audrey leaves her car in the lot for "t" hours, she would have to pay a total of $6 + $2t for parking.

If the mixture includes oats that cost $9.40 per kilogram and feed corn that costs $3.40 per kilogram, how many kilograms of each should the worker include in the mixture?
_?__ Kilograms of oats
_?__ Kilograms of feed corn
Answer:
168 kg oats and 252 kg corn
Step-by-step explanation:
2 equations and 2 unknowns
eq 1: x + y = 420
x is the amount of oats
y is amount of corn
eq 2: 9.4x + 3.4y = 5.8*420
solve equation 1 for x
x = 420 - y
substitute the value of x in eq 2
9.4(420-y) + 3.4y = 2436
y = 252
substitute y in eq 1
x + 252 = 420
x = 168

isha wants to paint the four walls of her living room.
Each wall is 2.6 m high and 3.5 m long.
One wall has a door of 2.2 m by 0.8 m.
Tins of paint cost £11 per 2 litre tin.
Each litre of paint can cover 8 m2 of wall.
There is an offer of: Buy 2 tins get the 3rd at half price.
How much will Aisha pay to paint her living room?
The amount Aisha would pay to paint her living room is £38.50.
What is the cost of painting the living room?The first step is to determine the area of the walls that do not have doors.
Area of a wall = length x width
3 x (2.6 x 3.5) = 27.30 m²
Dimensions of the wall with the door : (2.6m - 2.2m) x (3.5 - 0.8) = 0.4m x 2.7m
Area of the wall with the door : 0.4m x 2.7m = 1.08 m²
Total area of the walls: 27.30 m² + 1.08 m² = 28.38 m²
Number of paint tins needed for the walls : 28.38 / 8 = 3.55 = 4 tins
Cost of the paint tins : (11 x 3) + (0.5 x 11) = £38.50

Nora and her children went into a grocery store and see by $5 worth of apples and bananas each Apple cost $1 each banana costs $0.50. She bought 3 times as many bananas as apples. By following the stars below determine the number of apples, x, and the number of banana, y, that Nora bought.
Solving a system of equations, we will see that Nora bought 2 apples and 6 bananas.
How many apples and bananas Nora did bought?Let's define the variables:
x = number of apples.y = number of bananas.We know that She buys 3 times as many bananas as apples.
y = 3*x
The total cost is $5.
x*$1 + y*$0.50 = $5
Then we have a system of equations:
y = 3*x
x*$1 + y*$0.50 = $5
Replacing the first equation into the second one we get:
x*$1 + (3x)*$0.50 = $5
Now we can solve this for x.
x*$1 + x*$1.50 = $5
x*$2.50 = $5
x = $5/$2.50 = 2
So She bought 2 apples, and:
y = 3*x = 3*2 = 6
And 6 bananas.
