What is 5/6 of 14 1/2?
PLEASE explain how it is!
please help its last question and i been on it for 15 minutes
Answers
Answer:
5/6 of 14 1/2 is 12.08333333
Step-by-step explanation:
14 1/2 = 14.5
14 = 14
and 1/2 = 0.5
now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6
14.5 ÷ 6 = 2.416666667
and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number
2.416666667 × 5 = 12.08333333
So your answer is 12.08333333
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.
Grade#7
Answers
Answer: 4x+9
Step-by-step explanation: (8x+12)- (4x+3)
Answer: (4x+9)
Step-by-step explanation:
Log of wood = (8x+12)
piece length = (4x+3)
So, (8x+12) - (4x+3)
=> (8x+12) - 4x - 3
=> 8x-4x +12 -3
=> 4x + 9
So, the length of the remaining piece of wood = (4x+9)

A wallet contains 23 bills. All the bills are $1 bills and $5 bills. There are 7 more $1 bills than $5 bills. How much money does the wallet contain?
Answers
Answer:
Step-by-step explanation:
Let's say x is the number of $1 bills and y is the number of $5 bills. We know that:
x + y = 23
x = y + 7
We can use rearrange the second equation and add them together to find x. Then, we can plug x into any one of our equations to find y and calculate how much money is in the wallet.
x + y = 23
x - y = 7
2x = 30
x = 15 $1 bills
15 = y + 7
y = 8 $5 bills
15 * $1 + 8 * $5 = $15 + $40 = $55

Jasmine accidentally hot a golf ball through her neighbors window to replace the $150 window she pays her neighbor $10 of her tutoring earnings each week. Write an equation for each problem situation then graph each equation
Answers
Answer: y= -10x+150. The graph would have a slope of negative ten, cross the y-axis at (0, 150), and be decreasing. The line will cross the x-axis at (15,0), meaning it will take 15 weeks to pay her neighbor the money for the window.
Step-by-step explanation: y = the money Jasmine still owes to her neighbor. x = the # of weeks. She pays off ten dollars a week. She needs to pay 150 dollars to her neighbor.
Use the drop-down menus to complete the statements below to answer this question: Can you determine whether a system of linear equations has a solution just by looking at the graph of the equations?
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) ___.
If (−6,4) satisfies the equations of two lines, (−6,4) is ___ , so the lines will ___ at (−6,4).
This means that if two lines ____ at (−6,4), then (−6,4) is the ____ to the system of equations.
This means that if you substitute −6 for x and 4 for y in the equations, both equations will be ____.
Answers
Answer:
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.
If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).
This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.
This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true. However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations
Step-by-step explanation:
I Got You Bro
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.
If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.
If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).
This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.
This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true.
However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

168 cm
Explanation:
First we should find the area of the non-shaded parts
Length: 5cm
Width: 4cm
5x4=20
1st square= 20 cm
Length: 5cm
Width: 2cm
5x2= 10
2nd square= 10 cm
Now we add:
20+10=30
Shaded part:
11x18=198
We have to subtract the shaded part by the non shaded part:
198-30=168
Answer= 168cm
Page 2:

20+10=30
Rectangle 1=30cm
Rectangle 2:
Here we start to add and subtract:
Length: 10-5=5
Width: 6+5=11
5+5+11+11
10+22=32
32 cm
Total:
Now that we know both perimeters we add:

Answers
Step-by-step explanation:
One possible expression using two types of grouping symbols is:
3 × [(12 - (9 - 6))]
This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.

HURRYY! Will give Brainliest! The amount of sports drink in a cooler during practice is modeled by the equation
y = -24x + 648, where y is the number of ounces in the cooler after practice and x is the number of players at practice who take drinks from the cooler.
Based on the information in the equation, which statements are true?
A. The cooler is meant to be used by only 24 players.
B. Before practice, there are 648 ounces of sports drink in the cooler.
C. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink.
Answers
Answer:
Step-by-step explanation:
ounces of sports drink in the cooler.
C. Each player is expected to drink 24 ounces of sports drink during practice.
D. If no players take drinks from the cooler, there will be 648 ounces of sports drink in the cooler after practice.
Statement B is true: Before practice, there are 648 ounces of sports drink in the cooler, as the y-intercept of the equation is 648.
Statement C is not true: The coefficient of x, -24, does not represent the amount of sports drink each player is expected to drink. It represents the rate at which the amount of sports drink in the cooler decreases as players take drinks.
Statement D is not true: If no players take drinks from the cooler, x would be 0, and the amount of sports drink in the cooler after practice would be y = -24(0) + 648 = 648. However, this situation is not realistic, as players would normally take drinks from the cooler during practice.
Statement A is not true: The equation does not limit the number of players who can use the cooler. The equation only models the rate at which the amount of sports drink in the cooler decreases as players take drinks.
In mx+b, b is initial value meaning they started with 648 ounces

Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?
Answers
Answer:
1)23,800 plants.
2)$2,380,068,200
Step-by-step explanation:
1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.
2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.
In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.
If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.
Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.
Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.
Answer: she would sell 340 plants and make $9,999,900
Step-by-step explanation:
34 x 100 =340

Find the perimeter and area.
a. Rectangle, L=14m and B=9.5m
b. Square, side=14.5cm
c. Rectangle, L=25cm and B=16.8cm
Grade#8
Answers
Therefore, the perimeter and area of the given shapes are:
a. Perimeter = 47m, Area = 133m²
b. Perimeter = 58cm, Area = 210.25cm²
c. Perimeter = 83.6cm, Area = 420cm²
Step by step solved:
a. To find the perimeter of a rectangle with length L=14m and breadth B=9.5m, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(14m + 9.5m) = 2(23.5m) = 47m
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 14m x 9.5m = 133m²
b. To find the perimeter of a square with side length=14.5cm, we use the formula:
Perimeter = 4 x side
Plugging in the value, we get:
Perimeter = 4 x 14.5cm = 58cm
To find the area of the square, we use the formula:
Area = side²
Plugging in the value, we get:
Area = 14.5cm x 14.5cm = 210.25cm²
c. To find the perimeter of a rectangle with length L=25cm and breadth B=16.8cm, we use the formula:
Perimeter = 2(L+B)
Plugging in the values, we get:
Perimeter = 2(25cm + 16.8cm) = 2(41.8cm) = 83.6cm
To find the area of the rectangle, we use the formula:
Area = L x B
Plugging in the values, we get:
Area = 25cm x 16.8cm = 420cm²
Answer:
Step-by-step explanation:
rectangle Perimeter = 2(l+b)
So, 2(14+9.5)
=> 46.5m
area = lb
So, 14*9.5
=> 133m^2
Square Perimeter = 14.5*4
= 58cm
Area = 14.5^2
= 210.25m^2
Rectangle #2
2(25+16.8)
=> 83.6 cm
Area = 420m^2
