The sum of aanual interest and semi-annual compound interest on a sum of money for 2 years at the interest rate of 20% per annum is Rs. 18082. Find the differences.(Ans: Rs. 482)
The differences between the annual interest and semi-annual interest will be Rs 435.78.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
The same of annual interest and semi-annual compound interest on a same of money for 2 years at the interest rate of 20% per annum is Rs. 18082.
The annual interest will be
⇒ 18082(1.2)² – 18082
⇒ Rs 7956.08
The semi-annual interest will be
⇒ 18082(1.1)⁴ – 18082
⇒ Rs 8391.86
Then the differences between the annual interest and semi-annual interest will be
⇒ 8391.86 – 7956.08
⇒ Rs 435.78

Ms. Chawla’s class has 35 students. On children’s day, she gave 2 chocolates to each child in her class. After that, 5 chocolates were left with her. How many chocolates did she have at the start?
Answer:
75
Step-by-step explanation:
Total number of students = 35
Nø of chocolate received by each student = 2
Number of chocolates = 35 * 2 = 70
After the distribution of chocolate, remaining chocolates = 5
Then Now
Total chocolates = 70 + 5 = 75
Hope it will help :)
Answer:
75 Chocolates.
Step-by-step explanation:
She had 35 students and she gave each 2 chocolates. That's 70, but she had 5 left over. That makes the answer 75.

Answer: 6:5
Step-by-step explanation:
Let each little rectangle have the dimensions a by b (where a is the length and longer than b, the width). We find that l=3a because there are 3 lengths of a along l at the top of the crate and that l=4b because there are 4 lengths of b along l at the bottom of the crate. In addition, w=2b+a because there are 2 lengths of b and one length of a along w. Therefore, we can find b and a in terms of l and plug them into w=2b+a to find w in terms of l:
l=4b
b=l/4
l=3a
a=l/3
w=2b+a
w=2(l/4)+(l/3)
w=l/2+l/3
w=5l/6
If w=5l/6, l:w=l/(5l/6)=l(6/5l)=6/5
The correct answer is 6:5.
The number of lines shows 5/7 and 10/14. Which statement is true?
Answer:
[tex]\frac{5}{7} = \frac{10}{14}[/tex] because [tex]\frac{5}{7} = \frac{(5)(2)}{(7)(2)} = \frac{10}{14}[/tex].
Step-by-step explanation:
Looking at the number line, we can see that the highlighted parts go the same distance on the number line, therefore the fractions are equal. The number of equal parts, the size of a single equal part, or the denominators of two fractions do not matter. It's the total size made of up of those equal parts that counts.
Also, you can even convert [tex]\frac{5}{7}[/tex] into [tex]\frac{10}{14}[/tex] by multiplying BOTH the denominator and numerator by 2. When doing this with any number, regardless if it's 2, the original fraction and the converted fraction will still be equal.
On Monday, 414 students went on a trip to the zoo. All 9 buses were filled and 9 students had to travel in cars. Write an equation to find the number of students on each bus. Use b for your variable. Do not solve for b."
Step-by-step explanation:
let the total number of students in each bus be 'b',
Total number of students in 9 buses= 9b
Total number of students in cars= 9
Hence, Total number of students= 9b+9
= 414
Number of students in each bus = (414-9)/9

Select the graph for the solution of the open sentence lxl +3>3
No solution
Closed circle on 0 going to the right
Open circle going out left and right
Open circle only going to the right
Answer:
[tex]x>0\:or\:x<0[/tex]
As seen in graph, there is an open circle on 0, and it goes out left and right.
Option C is correct option.
Step-by-step explanation:
We need to draw the graph for the solution of the open sentence [tex]|x| +3>3[/tex]
First we will solve the inequality: [tex]|x| +3>3[/tex]
Adding -3 on both sides
[tex]|x| +3-3>3-3\\|x| >0[/tex]
We know that [tex]If\:|x|>0,\:then\:x>0\:or\:x<0[/tex]
So, we have
[tex]x>0\:or\:x<0[/tex]
Now, the graph is attached in the figure below
As seen in graph, there is an open circle on 0, and it goes out left and right.
Option C is correct option.
A 5.5-foot-tall woman walks at 8 ft/s toward a street light that is 22 ft above the ground. What is the rate of change of the length of her shadow when she is 20 ft from the street light? At what rate is the tip of her shadow moving?
Answer: [tex]\frac{8}{3}\ ft/s[/tex]
Step-by-step explanation:
Given
length of shadow =22 ft
height of woman =5.5 ft
speed of woman [tex]\frac{dy}{dt}=8\ ft/s[/tex]
from the figure, we can write
[tex]\frac{22}{x+y}=\frac{5.5}{x}[/tex]
at given instant
y=20 ft
so, using similar triangle properties
[tex]\frac{22}{x+20}=\frac{5.5}{x}\\22x=5.5x+110\\16.5x=110\\x=6.67\ ft[/tex]
Again we can write
[tex]\dfrac{22}{x+y}=\dfrac{5.5}{x}\\22x=5.5x+5.5y\\16.5x=5.5y\\3x=y\\\text{differentiate w.r.t time} \\3\frac{dx}{dt}=\frac{dy}{dt}\\\frac{dx}{dt}=\frac{1}{3}\times 8=\frac{8}{3}\ ft/s\ \text{away from the woman}[/tex]

Answer:
1/3
Step-by-step explanation:
slope is just change in y over change in x
on a graph this can be found by counting the change in units
look at the point at (-3,0)
find the change in y by starting at that point and counting up or down until you reach another point.
the next point (-4,-3) is three units down (change of -3)
now go back to the first point and count left or right until you reach the other point to get change of x
the other point is one unit left (change of -1)
change of y over change of x = -1/-3=1/3
Answer:
slope = 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, - 3) and (x₂, y₂ ) = (- 3, 0) ← 2 points on the line
m = [tex]\frac{0-(-3)}{-3-(-4)}[/tex] = [tex]\frac{0+3}{-3+4}[/tex] = [tex]\frac{3}{1}[/tex] = 3

This triangle has one side that lies on an extended line segment.
Based on this triangle, what statement about x is true?
x = 43 because 71−28=43 and 28 + 43 = 71
x = 81 because 180 − 71 − 28 = 81
x = 99 because 28 + 71 = 99 and 99 − 28 = 71
x = 137 because 180 − 71 + 28 = 109 + 28 = 137

The measure of angle x is; 137 degrees, the statement (4) x = 81 because 180 − 71 − 28 = 81 is true.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
In a triangle, the measures of the three angles add up to 180 degrees. In this triangle, one of the angles measures 71 degrees, and another angle measures 28 degrees.
Therefore, the measure of the third angle must be 48 degrees.
Since the measure of the third angle is 48 degrees, and the measure of one of the other angles is 33 degrees, the measure of the remaining angle must be 48 - 33 = 15 degrees.
Then the measure of the third angle must be 180 − 71 - 28 = 81 degrees.
Therefore, the measure of angle x is 81 degrees.

if 2 of the angles of a triangle are 30 and 70 degrees, the third angle measures ...
Answer:
The third angle measures 80°
Step-by-step explanation:
Let us solve the question
In any triangle
∵ The sum of the measures of the interior angles of a triangle is 180°
∵ The angle of triangles are ∠1, ∠2, and ∠3
∴ m∠1 + m∠2 + m∠3 = 180°
∵ Two of the angles of the triangle are 30° and 70°
∴ m∠1 = 30°
∴ m∠2 = 70°
→ Substitute them in the rule above
∴ 30° + 70° + m∠3 = 180°
→ Add the like terms
∵ (30 + 70) + m∠3 = 180
∴ 100 + m∠3 = 180
→ Subtract 100 from both sides
∵ 100 - 100 + m∠3 = 180 - 100
∴ m∠3 = 80°
∴ The third angle measures 80°
