A rectangular garden is surrounded by a path of uniform width 3m. If breadth of the garden is 40m and area of the path is 588m², find the length of the garden.
Answer:
52 m
Step-by-step explanation:
Width of the path = 3 mBreadth of the garden = 40 mLength of the garden = xArea of the path = 588 m²Area of the path is the difference of the of full area and the area of the garden.
Full area will have the sides:
40 + 3*2= 46 and x + 3*2 = x + 6Area of the garden is
40*xSo the difference is:
588 = (x + 6)*46 - 40*x588 = 46x + 6*46 - 40x588 = 6x + 2766x = 588 - 2766x = 312x = 312/6x = 52 mThe length of the garden is 52 m

There are 3 consecutive integers with a sum of 9. What is the value of the least integer?
Answer: 2,3,4
Step-by-step explanation: Which means that the first number is 2, the second number is 2 + 1 and the third number is 2 + 2. Therefore, three consecutive integers that add up to 9 are 2, 3, and 4.
Rose has to find a container big enough to fit a volume
of 60 in. The volume of the container is V = lwh.
Solve for height h. How tall does the container have
to be if the length is 5 in and the width is 4 in?
Answer:
The container is 3 inches tall
Step-by-step explanation:
Wright the equation
X is height
(4×5×X)=60
first multiply 4 and 5
20×X=60
Now multiply 20 and x
20x=60
divide by GCF (20)
x=3
The container is 3 inches tall

2. The following bar graph gives the percent of owners of three brands of trucks who are satisfied with their
truck. What is wrong with the way information is presented in this graph?
Answer:
Step-by-step explanation:
A histogram or a bar graph is used to show the big data having frequencies on the y-axis and range in which the data lie on x-axis.
In the given histogram there is no range of data.
Only percentage of customers who are satisfied with the different types of trucks have been given.
Therefore, to represent this data pie chart should be used instead of a histogram.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716. Find the number of orchestra seats and the number of balcony seats sold for the performance.
x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats
The number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716.
Let x be the number of Orchestra seats and y be the number of balcony seats. Then the equation will be
x + y = 257 ...1
12x + 8y = 2716 ....2
From equations 1 and 2, then we have
12x + 8(257 - x) = 2716
4x = 660
x = 165
Then the value of the variable y will be
165 + y = 257
y = 92
Thus, the number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.

The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions?
Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33
