Answer:
i) The area of the plot of land is 15,000 m²
ii) The base area of the school is 2,000 m²
iii) The volume of the school building is 30,000 m³
iv) The perimeter of the plot of land is 500 m
v) The cost of fencing the plot of land is Rs 2,500
Step-by-step explanation:
The parameters of the land, the school building and the cost of fencing are;
The length of the land, l = 150 m
The breadth of the land, b = 100 m
The dimensions of the school = 50 m × 40 m × 15 m
The cost of fencing the plot per meter = Rs 50 per meter
i) The area of the plot of land, A = Length × Breadth
∴ A = 150 m × 100 m = 15,000 m²
The area of the plot of land, A = 15,000 m²
ii) Taking the height of the school, h = 15 m, the length of the school building, [tex]l_B[/tex] = 50 m, and the breadth of the school building, [tex]b_B[/tex] = 40 m, the base area of the school, [tex]A_B[/tex], is given as follows;
[tex]A_B[/tex] = [tex]l_B[/tex] × [tex]b_B[/tex]
∴ [tex]A_B[/tex] = 50 m × 40 m = 2,000 m²
iii) The volume of the school building, V = h × [tex]l_B[/tex] × [tex]b_B[/tex]
∴ V = 15 m × 50 m × 40 m = 30,000 m³
iv) The perimeter of the plot of land, P = 2 × l + 2 × b
∴ P = 2 × 150 m + 2 × 100 m = 500 m
The perimeter of the plot of land, P = 500 m
v) The cost of fencing the plot of land, C = P × (The cost of fencing the plot per meter )
∴ C = 500 m × Rs 50/m = Rs 2,500
The cost of fencing the plot of land, C = Rs 2,500

how do I check my work for two step equations?
For a 2 step equation, I'm guessing you are talking about this kind of equations.
2x+3=5
In these equations you solve it first.
2x=2
x=1
Now to check your work you simply substitute it back in to see if the equation stands.
2*1+3=?=5
2+3=5
This equal sign stands when I substitute it back so therefore its correct.
That's what checking your work means, this is how you check your work for most solve for x problems :)

An alligator is 9 inches long at birth and grows 10 inches per year. Write an equation that represents the length y (in feet) of an alligator that is x years old. How long will the alligator be after 4 years?
Answer:
y=10x+9
after 4 years the gator will be 49 in long
Step-by-step explanation:
Answer:
y = 5/6x + 3/4.
At 4 years old, the length y = 49/12 feet = 4 feet 1 inch.
Step-by-step explanation:
9 inches = 3/4 feet.
10 inches = 5/6 feet
So our equations is
y = 5/6x + 3/4.
When it is 4 years old:
y = 5/6(4) + 3/4
= 20/6 + 3/4
= 49/12 feet

What is the area of the circle below? Use π = 3.14 to solve. Round your answer to the nearest hundredth.
Answer:
803.84 ft ²
:)
The area of the circle is given by the equation A = 803.84 feet²
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the area of the circle be represented as A
Now , the equation will be
The radius of the circle r = 16 feet
So , area of the circle = πr²
Substituting the values in the equation , we get
Area of the circle A = π x ( 16 )²
Area of the circle A = π x 256
Area of the circle A = 3.14 x 256
Area of the circle A = 803.84 feet²
Therefore , the value of A is 803.84 feet²
Hence , the area of circle is 803.84 feet²

Which bag gives you more free rice.
Show your working.
Answer: rice a
Step-by-step explanation:
convert 1/5 to a decimal .20 <.25
Bag of rice B gives more rice than bag A as per the percentage.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
Given, A shop sells two different bags of rice. Rice A has 500g plus 25% extra free and Rice B has750g plus 1/5 extra free.
For calculating the free amount of rice,
For Bag A
Frre amount of rice = 500* 25% = 500 *25/ 100 = 125g
For Bag B
Frre amount of rice = 750 * 1/5 = 150g
Therefore, According to the percentage, bag B of rice contains more rice than bag A.

Answer:
Step-by-step explanation:
Draw a picture. You have a 30-60-90 triangle, so the sides are in the ratio 1:√3:2.
The string of the kite is the side opposite the 90° angle. The side opposite the 30° angle is 25 ft.

ABCD- parallelogram, If the perimeter of Triangle CPQ is 15cm, Find the perimeter of triangle BAQ. Find the perimeter of triangle PDA. PLEASE FIND THE ANSWER QUICKLY I NEED IT RIGHT NOW
Answer:
The answer is below
Step-by-step explanation:
A parallelogram is a quadrilateral (has 4 sides and 4 angle) with two pair of parallel and opposite sides. Opposite sides of a parallelogram are parallel and equal.
Given parallelogram ABCD:
AB = CD = 18 cm; BC = AD = 8 cm
∠P = ∠P, ∠PDA = ∠PCQ (corresponding angles are equal).
Hence ΔPCQ and ΔPDA are similar by angle-angle similarity theorem. For similar triangles, the ratio of their corresponding sides equal. Therefore:
[tex]\frac{CD}{PC}= \frac{AD}{CQ}\\\\\frac{18}{6}=\frac{8}{x} \\\\x=\frac{6*8}{18}=\frac{8}{3}\ cm[/tex]
Perimeter of CPQ = CP + CQ + PQ
15 = 6 + 8/3 + PQ
PQ = 15 - (6 + 8/3)
PQ = 6.33
∠CQP = ∠AQB (vertical angles), ∠QCP = ∠QBA (alternate angles are equal).
Hence ΔCPQ and ΔABQ are similar by angle-angle similarity theorem
[tex]\frac{AQ}{QP}=\frac{AB}{CP} \\\\\frac{AQ}{6.33} =\frac{18}{6} \\\\AQ=\frac{18}{6}*6.33\\\\AQ = 19[/tex]
[tex]\frac{BQ}{CQ}=\frac{AB}{CP} \\\\\frac{BQ}{8/3} =\frac{18}{6} \\\\BQ=\frac{18}{6}*\frac{8}{3} \\\\BQ =8[/tex]
Perimeter of BAQ = AB + BQ + AQ = 18 + 8 + 19 = 45cm
PA = AQ + PQ = 19 + 6.33 = 25.33
PD = CD + DP = 18 + 6 = 24
Perimeter of PDA = PA + PD + AD = 24 + 25.33 + 8 = 57.33 cm

As per information in the question,
Price of greeting card = $3.79
Total cost of greeting card as well as greeting card is $5.11
Let the price of each postcard is x.
Then, the equation will be,
$3.79 + 4x = $5.11

What is the distance between 4 and 17?
Answer:
14
Step-by-step explanation:
17 - 4 + 1 = 13 + 1 = 14
Answer:
Step-by-step explanation:
D = distance
[tex]x_{1}[/tex] = 4
[tex]x_{2}[/tex] = 17
No "y" values were given.
The distance formula:
[tex]D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}[/tex]
If we insert in the values:
[tex]D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}[/tex]
(0-0)^2 = 0 so we can just remove the last part since it's +0:
[tex]D = \sqrt{(4 - 17)^{2}}[/tex]
4 - 17 is equal to -13:
[tex]D = \sqrt{(-13)^{2}}[/tex]
Since [tex](-a)^{2} = (a)^{2}[/tex], that means that the negative 13 becomes positive
[tex]D = \sqrt{(13)^{2}}[/tex]
Now the square root and the square cancels each other out:
[tex]D = 13[/tex]

First we need to find the value of the black sqaure. The value of the black square is 6 because 60 / 10 = 6. A) cannot be the answer because 6 does not equal 60. C) cannot be the answer because 10 does not equal 360. The only answer can be B) because 6 x 10 does equal 60.
Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic. y2 + 28y +
Answer:
[tex]y^2+28y+196[/tex]
Step-by-step explanation:
We are given that
[tex]y^2+28y+..[/tex]
We have to fill in the number that makes the polynomial a perfect square quadratic.
We know that
[tex](a+b)^2=a^2+2\times a\times b+b^2[/tex]
Using the formula
Expand the expression
[tex](y)^2+2\times y\times 14+(14)^2[/tex]

[tex]=y^2+28y+196[/tex]
If the parent function is y = x², explain the transformation(s) that occur to get from
the parent function to y = 3x? – 2
The parent function is y = x²
If we vertically stretch it by a factor of 3, then we get to y = 3x²
So it's 3 times taller than it used to be. A point like (2,4) moves to (2,12) after applying this vertical stretch. Because it's stretched vertically, it becomes more narrow in the horizontal direction.
If we then shift that down by 2 units, then we arrive at the equation y = 3x²-2
So to summarize, we applied these two transformations:
Vertically stretch by a factor of 3Shift down 2 unitsThe graph is shown below.
