A playground measures 300 m × 170 m.Find the cost of planting grass on this at the rate of Rs 80 per hectare.
To find the cost of planting grass , we have to find area of the field.
Area of field = Length × Breadth
[tex]{= 300×170}[/tex]
[tex]{=51000 sq. m}[/tex]
Now convert into hectare.
1 hectare = 10000m sq.
51000 / 10000
So area field = 5.1 hectare sq.
Now cost = 5.1 x 0.80 p
[tex]{= 0.408 p}[/tex]
___________3(3 - x) = 5(2x + 7) solve for x
Answer:
x = -2
Step-by-step explanation:
3(3 - x) = 5(2x + 7) multiply 3 with both 3 and -x then 5 with 2x and 7
9 - 3x = 10x + 35 add like terms
9 - 35 = 10x + 3x
-26 = 13x
x = - 2
Are 2/3 and 3/2 equivalent
Answer:
no.
Step-by-step explanation:
let's use apples for this example. if you have 3/2 of an apple that means you actually have one full apple and one apple cut in half since 3/2 is also equal to 1 and 1/2. but 2/3, on the other hand, means you have 2 of 3 sections of 1 apple.
Answer:
no they are not
Step-by-step explanation:
use an equivalent fraction calculator on google to find fractions equivalent!

Find the area.
7 cm
17 cm
25 cm
Answer:
272cm squared
Step-by-step explanation:
figure a, a traingle... to find area formula is
1/2×b×h
1/2×18×17
153
figure b, it's rectangle.so length×width
=7×17
=119
area of the shape=153+119
=272cm squared
Answer:
D. 272 cm²
Step-by-step explanation:
will make it easy and short
use the area of a trapezoid = (a + b) * h/2
where a = 25, b = 7, h = 17
Area = (25 + 7) * (17/2)
Area = 32 * 8.5
Area = 272 cm²
HELP ASAP!!!!!!!!!!!
Answer:
C
Step-by-step explanation:
the statement (y<1/2x -4) reads "y is LESS than 1/2 x -4."
to fulfil this statement, follow these steps.
1) graph the line 1/2x -4, there will be a yintercept at (0,-4). Also the slope will be increasing (left to right) because 1/2 has no negative sign before it.
2) recognize the inequality sign. In this situation, the solution does NOT INCLUDE THE LINE, rather it includes the area BELOW/LESS THAN the line. If this, < had a line under it, it would mean less than OR equal to.
3) know that if the line is not included, the line will be broken. If the line IS included, which it is not, it would be a solid line.
Answer:
C
Step-by-step explanation:
First, graph the equation:
The y-intercept is -4.
And the slope is 1/2, an upward sloping line.
So, our graph should be either A, B, or C.
D is not correct, so eliminate that.
So, our inequality is:
[tex]y<\frac{1}{2}x-4[/tex]
Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.
Thus, eliminate A and B.
So, C is our answer
Further notes:
The inequality sign means that y is less than the equation. In other words, our shaded region should be below the line.
In C, the shaded area is indeed below the line.
So, C is indeed our answer :)
Solve the linear equation for y.
-8=-10x + 5y
Answer:
-8/5 + 2x = y
Step-by-step explanation:
-8=-10x + 5y
Add 10x to each side
-8+10x=-10x+10x + 5y
-8+10x = 5y
Divide each side by 5
-8/5 + 10x/5 = 5y/5
-8/5 + 2x = y
[tex]\sf\dashrightarrow -8=-10x + 5y [/tex]
[tex]\sf\implies -8=5(2x+y)[/tex]
[tex]\sf\implies \dfrac{-8}{5}=-2x+y [/tex]
[tex]\sf\implies \dfrac{-8}{5}+2x=y[/tex]

How much will fertilizer cost for a field 725 feet by 1,021 feet if one bag covers 10,000 square feet and costs $12.97 per bag?
Answer:
$9600.72
Step-by-step explanation:
Area of the field = length × width
Length = 1,021 feet
Width= 725 feet
Area of the field = length × width
= 1,021 feet × 725 feet
= 740,225 square feet
One bag covers 1000 square feet
There are 740,225 square feet
Find the number of bags that will cover the total of 740,225 square feet
Total bags = 740,225 / 10000
=740.225 bags
A bag cost $12.97
Total cost of 740.225 bags= 740.225 × 12.97
= $9600. 71825
Approximately
$9600.72
plssssss answer quick Hudson bought a plant and planted it in a pot near a window in his house. The initial height of the plant was 8 inches and it grew at a rate of 3 inches per month. Write an equation for H,H, in terms of t,t, representing the height, in inches, of the plant tt months after Hudson bought the plant.
Answer:
H = 8 + 3t
Step-by-step explanation:
H = height
t = time in months
H = 8 + 3t
H is the height at and given time. 8 is the initial height and since it grows 3 in a month it would be 3 times how ever many months have passed.
For example after 6 months
t = 6
H = 8 + 3 (6)
H = 8 + 18
H = 26in

how do i find the Domain and Range in Inequality form
Answer:
Domain is the set of all x values, the independent quantity, for which the function f(x) exists or is defined.
Step-by-step explanation:
i just graphed it
Answer:
Domain:
[tex]x\in\mathbb{R}[/tex]
Range:
[tex]y\geq -5[/tex]
Step-by-step explanation:
The domain is the span of x-values covered by the graph, and the range is the span of y-values covered by the graph.
From the graph, we can see that the x-values covered by the graph will extend infinitely in both directions. Therefore, the domain of the graph is all real numbers.
We can't write this as an inequality, but we can write:
[tex]x\in\mathbb{R}[/tex]
For the range, we can see from the graph that the lowest y-value is y=-5. The graph doesn't go any lower than that. However, the graph will also cover all values greater than -5. Therefore, the range of the graph is all values greater than or equal to -5. In an inequality, this is:
[tex]y\geq -5[/tex]

At the movie theatre, child admission is $6.40 and adult admission is $9.50. On Sunday, 165 tickets were sold for a total sales of $1266.80. How many adult tickets were sold that day?
Answer:
68Step-by-step explanation:
1. Define unknowns:
x - number of adult tickets ($9.50 each)y - number of child tickets ($6.40 each)2. Make system of equations:
[tex]x+y=165[/tex] [tex]9.5x+6.4y=1266.8[/tex]3. Multiply both sides of first equation by 6.4:
[tex]6.4x+6.4y=1056[/tex] [tex]9.5x+6.4y=1266.8[/tex]4. Subtract first equation from second one:
[tex](9.5x-6.4x)+(6.4y-6.4y)=1266.8-1056[/tex] [tex]3.1x=210.8[/tex] [tex]x=68[/tex]What is the probability of getting a odd number when you roll a dice
Answer:
50% (1/2)
Step-by-step explanation:
3 of the 6 sides that exist on a dice have odd numbers.
Answer:
1/2 probability of getting an odd number
Step-by-step explanation:
Dice have the given outcomes of getting a 1, 2, 3, 4, 5, or 6. Considering that the desired outcomes are only 3 out of 6 of those given outcomes, that leaves us with a 3/6 or 1/2 chance of getting an odd number.

Answer and Step-by-step explanation:
Areas of mathematics, and give a precise definition of each.
Sol: importance: mathematics can be tricky, so precise definitions are essential. Without them, there can be confusion, which will generate the wrong answer more often than not. It teaches the students exactly how to use formulas and under what condition a mathematical statement is true.
Some words related to geometry that are quite hard to define precisely are the line, the plane, and the point. In mathematics, the unit square is area one and any other shape.

Mya has an exercise ball in the shape of the sphere shown below.She wants to increase the weight of the ball by filling it with water. Which is closest to the amount of water in cubic inches,that Mya's exercise ball will hold if it is completely full?
Answer: Volume of a sphere = 4/3 * pi * r^3 r = radius of sphere pi~ 3.14
Step-by-step explanation: If you use the radius in inches, your result will be in cubic inches (in^3)
The amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.
What is the volume of a sphere?The volume of a sphere is the volume of space occupied by a sphere. It is given by the formula:
[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]
As it is given that the diameter of Mya's ball is 12 inches, also we know that the volume of a sphere is given by the formula,
[tex]\text{Volume of Sphere} = \dfrac{4}{3}\pi r^3[/tex]
As we know that the diameter of Mya's ball is 12 inches, therefore, the radius of Mya's ball can be written as,
[tex]\rm Radius = \dfrac{Diameter}{2} = \dfrac{12\ in}{2} = 6\ in.[/tex]
Now, if we substitute the value of the radius of Mya's ball in the formula of the volume of the ball,
[tex]\rm \text{Volume of Ball} = \dfrac{4}{3}\times \pi \times 6^3 = 904.779\ in^3[/tex]
Hence, the amount of water in cubic inches, that Mya's exercise ball will hold is 904.779 in³.
