Find the simple interest.
Principal
Rate 11% principle 9000 time1 1/2 years what's the amount of simple interest earned is
Answer:
Here is your answer. Hope this helps you!
Answer:
Rate(R)= 11%
Times(T)=11/2
Principle(P)= 9000
We know that,
SI = P×T×R÷100
= 9000×11/2×11÷100
=9000×5.5×11÷100
= 544500÷100
=5445
Hence, the required simple interest is 5445.

in class of 80 student debre berhan university ,45 are good in mathematics,15 are good in both mathematics and in english,13 are good in both mathematics and psychology,16 are good in both english and psychology only,20 are good in psychology and 9 are good in both of three courses.how many students are not good in any of three courses ?
We want to find the number of students that are not good in any of the courses.
There are 80 students.
45 are good in mathematics
15 are good in both, mathematics and in English
13 are good in both, mathematics and psychology
16 are good in both English and psychology
20 are good in psychology
9 are good in all of the courses.
First, we know that we have:
45 good in math + 20 good in psychology = 65 students good in something.
But we know that:
13 are good in both, mathematics and psychology
This means that there are 13 students that are being counted twice, so we need to subtract 13.
45 + 20 - 13 = 52 students good in something.
Now we know that:
15 are good in both, mathematics and in English
16 are good in both English and psychology
9 are good in all of the courses.
So one would want to also count these students, but notice that these are already good in mathematics or in psychology, so these are already counted.
And we can't see the number of students that are only good with English, so we can conclude that
52 students are good in something.
then 28 students are not good at any of the 3 courses.

Solve for d when t = 0, t = 3, t = 5 d =2t
Answer:
When t = 0, d = 0When t = 3, d = 6When t = 5, d = 10Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
PART ONE: Find d when t = 0
Given expression
d = 2t
Substitute value into the expression
d = 2 (0)
d = 0PART TWO: Find d when t = 3
Given expression
d = 2t
Substitute value into the expression
d = 2 (3)
d = 6PART THREE: Find d when t = 5
Given expression
d = 2t
Substitute value into the expression
d = 2 (5)
d = 10Hope this helps!! :)

The equivalent expressions are 3^4 and -9^2
How to determine the equivalent expressions?To determine the equivalent expressions, we simply solve the options.
So, we have:
3^9 = 19683
3^4 = 81
-9^2 = 81
9^9 = 387420489
From the above computation, we have:
3^4 = 81 and -9^2 = 81
Hence, the equivalent expressions are 3^4 and -9^2

Formula-
If a set has “n” elements, then the number of subset of the given set is 2n and the number of proper subsets of the given subset is given by 2n-1. Consider an example, If set A has the elements, A = {a, b}, then the proper subset of the given subset are { }, {a}, and {b}
Symbol that can be used-
The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".

Anyone know how to solve it?
Answer:
[4 -2 -19]
[-1 1 8]
Step-by-step explanation:
[ 2 5] * [a b c] = [3 1 2]
[ 1 3] ld e f] [1 1 5]
[2a+5d 2b+5e 2c+ 5f] = [3 1 2]
[a+3d b + 3e c + 3f] [1 1 5]
Solving systems of equations:
2a + 5d = 3
a + 3d = 1
2a + 6d = 2
Subtract -d = 1 so d = -1
and a = 1 - 3d = 1 - 3(-1) = 4
So d = -1 and a = -4.
In the same way we find that b = -2, e = 1, c = -19, f = 8.
Help please! Find the area of the shape below. (Show work)
9514 1404 393
Answer:
292 yd²
Step-by-step explanation:
We can find the area of the remaining L shape by subtracting the area of the 21×22 rectangle at lower left from the 26×29 overall rectangle.
shape area = (26 yd)(29 yd) -(21 yd)(22 yd) = 754 yd² -462 yd²
shape area = 292 yd²
__
Additional comment
The area of a rectangle is the product of its length and width.
There are many ways the area of this shape can be calculated. The area can be divided into two rectangles, two trapezoids, three rectangles, and other ways.
If you cut up the given shape into smaller pieces, you will generally need to know the widths of the arms of the L. One of those is shown as 7 yd. The other is 26-21 = 5 yd.
Using the method we did, we only needed the dimensions shown on the figure.

find the radius of a circle which has a sector of area 9 square meters determined by a central angle 1/3 radian
Answer:
L = length of arc , R = radius
radian angle = L / R
L = R* radian angle
L = R * 1/3
L = R/3 #1
Area of sector = 1/2 L*R
By substitution using #1
Area of sector = 1/2 * R/3 * R
9 = R^2 /6
R^2= 6*9
R^2= 36
R =✓36
R = 6
