Answer: 7.71%
Step-by-step explanation:
Number of students in a school last year = 700
Number of students in a school this year = 646
Reduction in the number of students = 700 - 646 = 54
The percentage reduction will be:
= Reduction in number / Last year students × 100
= (54 / 700) × 100
= 7.71%

Ashin has been working in UAE for a decade and saved AED 125,500 which he wants to transfer now to his parent's account in India. Keeping in mind the AED – INR exchange rate for the day, which is AED 1 = 20 (approx.), find the amount of money which Arshad's parents will withdraw in India.
Answer:
2510000 INR
Step-by-step explanation:
Given
[tex]Savings = AED 125500[/tex]
[tex]1\ AED =20\ INR[/tex]
Required
The amount that will be withdrawn in India
We have:
[tex]1\ AED =20\ INR[/tex]
Multiply both sides by the savings
[tex]125500 * 1\ AED =20\ INR * 125500[/tex]
[tex]125500\ AED =125500 * 20\ INR[/tex]
So, we have:
[tex]125500\ AED =2510000\ INR[/tex]
Hence, the amount that will b withdrawn is: 2510000 INR
Simplify (2-6)(5)(23 . 5)2.

Answer:
x = 35
Step-by-step explanation:
The proper equation of proportions is
x 42
----- = ------ and it yields x = 35
40 48
Answer:
? = 35
Step-by-step explanation:
The lengths of corresponding sides of similar polygons are in the same ratio.
The sides measuring 48 and 40 are corresponding sides.
The ratio of their lengths is 48/40.
The sides measuring 42 and ? are also corresponding, so they are in the same ratio.
That means we can set up a proportion to solve for the side with length ?.
48/40 = 42/?
Simplify the fraction on the left side.
6/5 = 42/?
Cross multiply.
6 * ? = 5 * 42
Divide both sides by 6.
? = 5 * 7
? = 35

Solve (x - 3)^2+7=97, where X is a real number. Round your answer to the nearest hundredth.
Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ± [tex]\sqrt{90}[/tex] ( add 3 to both sides )
x = 3 ± [tex]\sqrt{90}[/tex]
Then
x = 3 - [tex]\sqrt{90}[/tex] ≈ - 6.49 ( to the nearest hundredth )
x = 3 + [tex]\sqrt{90}[/tex] ≈ 12.49 ( to the nearest hundredth )

Points A and B have the same x-coordinates but opposite y-coordinates. point A is 4 units to the left and 3 units up. Point B is 4 units to the left and 3 units down. How many units away are each of the points from the y-axis? 3 4 6 7
Answer:
4 Units
Step-by-step explanation:
The x-coordinate of points A and B is -4, the y-axis vertically at x=0.
Therefore point A and B are 4 units away from the x-axis.

The perimeter of an equilateral triangle is 9 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. Find the side of the triangle.
Answer:
9 inches
Step-by-step explanation:
Perimeter of equilateral triangle = 3x
Perimeter of square = 4x
3(x + 6) = 9 + 4x
3x + 18 = 9 + 4x
-x = -9
x = 9

Thanks to both of the people that’s helping mee!!❤️
Answer:
s = 17 inches
Step-by-step explanation:
Since this is a parallelogram, it has two sets of equal sides. We are given that one of the sides is 19 and the perimeter is 72. Therefore, \
72 = 2*s + 2*19
72 = 2*s + 38
34 = 2*s
s = 17
Answer:
17
Step-by-step explanation:
19 + 19 = 38
38 divided by 2 = 17
Add the given length to itself again because the other side is equal.
Which would be 38. Divide by 2 since there are two missing lengths that need to be solved (s). And your final answer is 17!

Quadrilateral LMNO is similar to quadrilateral PQRS. Find the measure of side QR.
Round
your answer to the nearest tenth if necessary. Figures are not drawn to scale.
Answer:
The measure of the side [tex]QR[/tex] is 8.8.
Step-by-step explanation:
Since [tex]LMNO \sim PQRS[/tex], then [tex]SP \propto OL[/tex], [tex]RS \propto ON[/tex], [tex]RQ \propto MN[/tex] and [tex]QP \propto LM[/tex]. From figure we have the following relationship:
[tex]k = \frac{OL}{SP} = \frac{ON}{RS} = \frac{MN}{QR} = \frac{ML}{QP}[/tex] (1)
Where [tex]k[/tex] is the proportionality ratio.
If we know that [tex]SP = 13, OL = 55, MN = 37[/tex], then the measure of side [tex]QR[/tex] is:
[tex]k = \frac{OL}{SP}[/tex] (1b)
[tex]k = \frac{55}{13}[/tex]
[tex]k = \frac{MN}{QR}[/tex]
[tex]QR = \frac{MN}{k}[/tex] (1c)
[tex]QR = \frac{37}{\frac{55}{13} }[/tex]
[tex]QR = 8.745[/tex]
The measure of the side [tex]QR[/tex] is 8.8.
What is the perimeter of the rectangle with the vertices shown below? A(4, 7), B(4, 15), C(9, 15), D(9,7)
Answer:
[tex]X=26[/tex]
Step-by-step explanation:
From the question we are told that:
Co_ordinates of rectangle:
[tex]A(4, 7),\\ B(4, 15),\\C(9, 15),\\D(9,7).[/tex]
Generally the equation for rectangular Perimeter X is is mathematically given by
[tex]X=2(length+breath)\\X=2L+2B[/tex]
Generally the Length of the rectangle is mathematically given by
[tex]L=(y\ axis\ co-ordinate\ of\ C)-(y\ axis\ co-ordinate\ of\ D)\\or\\L=(y\ axis\ co-ordinate\ of\ B)-(y\ axis\ co-ordinate\ of\ A)[/tex]
Therefore
[tex]L=15-7\\L=8[/tex]
Generally the Breath of the rectangle is mathematically given by
[tex]B=(x\ axis\ co-ordinate\ of\ D)-(x\ axis\ co-ordinate\ of\ A)\\or\\B=(y\ axis\ co-ordinate\ of\ C)-(y\ axis\ co-ordinate\ of\ B)[/tex]
Therefore
[tex]B=9-4\\B=5[/tex]
Generally the rectangular Perimeter X is is mathematically given by
[tex]X=2(8)+2(5[/tex]
[tex]X=26[/tex]

Two shops sell the same brand of baked beans but in different sizes of tin. Calculate the price of 1 kg of baked beans for each shop. Give your answers in pence.
Answer:
Shop A = 113 pence
Shop B = 101 pence
Step-by-step explanation:
Given :
Shop A :
5kg for £5.65
Shop B:
2kg for £2.02
Price per kg :
weight / price
100 pence = £1
Shop A :
Price of 1kg :
5.65 / 5 = £1.13 = 113 pence
Shop B:
2.02 / 2 = £1.01 = 1.01 * 100 = 101 pence

Answer:
m∠A = 120°
m∠C = 45°
Step-by-step explanation:
all triangle angles add up to 180
(12x + 12) + 15 + (3x +18) = 180
15x + 45 = 180
15x = 135
x = 9
m∠A = (12x + 12) = 12(9) + 12 = 120
m∠C = (3x +18) = 3(9) + 18 = 45
