find the rate of interest when principal rs 6400 SIMPLE INTEREST RS 768 and time 2 years
Answers
Answer:
rate of interest is 6 percent per annum.
Step-by-step explanation:
Formula for simple interest is given
SI = p*r*t/100
where
SI is simple interest
p is principal
r is the rate of interest
t is the time
_______________________________
Given
p = 6400
SI = 768
t = 2 years
r we have to find
lest sue the above formula and plug the given value in it
768 = 6400*r*2/100
=> 768 = 128r
=> r = 768/128 = 6
Thus, r = 6%
thus, rate of interest is 6 percent per annum.

I need help with exponents , im a little stuck
Answers
Answer:
Exponents are when you are multiplying numbers by themselves. The symbol is this sign right here ^
Step-by-step explanation:
Exponents are usually shown as ^
but they may also look more like a number that is on the top right corner of a value.
When you have an exponent, since you are multiplying by itself, you get the number times the number times the number on and on, counting on what the value of the exponent is.
If the number looks like this for example 2^5
You should either see that or a 2 with a 5 hugging the top right corner of the 2.
To solve them, you should do 2 x 2 x 2 x 2 x 2, since you are multiplying the 2 by itself 5 times.
2^1 is basically just 2, as you are multiplying 2 by itself no times at all.
2^2 should be 4, because you are multiplying 2 by 2 twice.
2^3 is 2 x 2 x 2 which is 4x2 which is 8.
When a number goes to the power of 0, such as 2^0 it is ALWAYS 1. For some weird reason, exponents going to the power of 0 is always 1, no matter what value the bottom number is.
1^0 = 1
2^0 =1
19442380528^0 = 1
Exponents to the negative power, are more difficult, however is just as easy as remembering the powers of 0.
You just flip the number upside down, so if the number is 3^-2 then it becomes 1/3 ^2
If the number is 3^-4
You get 1/3 x 1/3 x 1/3 x 1/3 which you end up getting 1/81.
You have to square the top numbers too when you are using exponents, so if 2/3 to the power of 3 is used,
you have to do 2/3 times 2/3 times 2/3, which is 2x2x2 over 3x3x3 giving you 8/27.
The same principle applies to when you do negative exponents, which you are just flipping over the fraction or number and doing the exponent.
2/3 to the power of -3, would give you 3/2 times 3/2 times 3/2, which gives you 27/8.
I will not get into much more detail, as it is a big unit to go through, but once you get the hang of them, it is easy to understand. I appologize if you feel lost, but there are many websites that go into more detail much better than me. Khan Academy gives VERY in depth videos on how exponents work with some humor, but I hope this helped at least!

Use the formula C = 5 (F – 32). To determine which temperature is hotter.
30° Celsius or 85° Fahrenheit. Write just the number as your answer.
Answers
Answer:
Step-by-step explanation:
The formula u have written is incorrect. It should be C = [5 (F-32)]÷9.
To identify which is hotter, you need to bring both the values either in celsius or in Fahrenheit.
Let's convert 85°F to celsius:
C = [5 ( F - 32 )] ÷ 9
C = [5 ( 85-32 )] ÷ 9
C = [5 (53)] ÷ 9
C = 29.4 °C
thus 30°C is hotter than 85°F

Answers
Answer:
a = 69
b = 47
c = 116
d = 93
e = 86
See ALL MATH below!
Step-by-step explanation: (PLEASE READ!!!) ;3
remember that the sum of all the angles in a triangle will always add up to be 180.
All angles in a quadrilateral will be 360.
Pentagon, 540, and the center shape in your problem, hexagon, 720°
It's easier to think about this problem when you look at the two separate triangles, and not the small individual shapes. SO...
one of them, the one that points down, only has a single missing angle (a)
we can find that by doing this:
40 + 71 = 111
180 - 111 = 69
so a = 69
to find B, it's actually more simple. b+133, the angle next to it, will add up to 180, because it's a straight line. so...
180-133 = 47, so B = 47
now that you have a and b, we can find c by using the same method we used to find b, but first we need the angle next to it, so we use the method to find a!
180 - (a + b) = needed angle
180 - needed angle = c
69 + 47 = 116
180-116 = 64
now we have 64. we will subtract that from 180 to get c!
180- 64 = 116
the easiest way to find d is to find the other angle in that small triangle to the bottom right, so we'll subtract 140 from 180, which is 40. 47 + 40 = 87
180 - 87 = 93
d = 93!
finally for e, I'm going to do my work below, I'll have to find many other angles to get e, so maaaaybe you'll be able to follow along.
71+40=111, 180 - 111 = 69
180 - 69 = 111
111 is the angle to the left of the given 140.
NOW we can focus on that little triangle to the left, after we get the bottom left most angle, we can add that with 47, subtract it from 180, and we'll have e!!!
180-111 = 69 (bottom right angle of little triangle)
180-116 (c) = 64 (top angle)
69 + 64 = 133
180 - 133 = 47!!
Now we have two angles of the large triangle that points up. using them, we can find the last one, E.
47 + 47 = 94
180 - 94 = e

Answers
Answer:2
Step-by-step explanation:
I have the problem on my my review and it says 2
Substituting the given values of X into the function, the value of f(3) - f(4) is 2
Given the function :
f(x) = - 2x + 3f(3) = - 2(3) + 3
f(3) = - 6 + 3 = - 3
For X = 4 :
f(4) = - 2(4) + 3
f(4) = - 8 + 3 = - 5
f(3) - f(4) = - 3 - (-5)
f(3) - f(4) = - 3 + 5 = 2
Therefore, the value of f(3) - f(4) is 2

A bee flies at 12 feet per second directly to a flower bed from its hive. The bee stays at the flower bed for 13 minutes then flies directly back to the hive at 8 feet per second. It is always away from the hive for a total of 15 minutes. What equation can you use to find the distance of the flower bed to the hive?
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Rate of flight = 12 feets per second ; from hive to flower bed
Minutes stayed at flower bed = 13 minutes
Rate of flight = 8 feets per second ; from flower bed to hive
It is always away from the hive for a total of 15 minutes
What equation can you use to find the distance of the flower bed to the hive?
Distance = speed * time
Time = distance / speed
Let distance from flowerbed to hive = d
Time from hive to flower bed = d/12
Time from flower bed to hive = d / 8
Hence, total time taken;
d/12 + 13 + d/8 = 15
Converting minutes to seconds
d/12+ 13*60 + d/8 = 15*60
d/12 + 780 + d/8 = 900
Take the L. C. M
(2d + 18720 + 3d) / 24 = 900
5d + 18720 = 21600
We can also solve for d
5d = 21600 - 18720
5d = 2880
d = 576 feets

As a farmer, Felipe keeps a close eye on the weather. After a few stressful weeks with no rain, Felipe was relieved when it started raining one morning. It rained steadily all day, and Felipe periodically checked to see how much rain had fallen. There is a proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) that had fallen, y. The equation that models this relationship is y=0.25x. At this rate, how long did it take until 2 inches of rain have fallen? Write your answer as a whole number or decimal.
Answers
Answer:
The time it took until 2 inches of rain fell is 8 hours
Step-by-step explanation:
You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x
To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:
2= 0.25*x
Solving:
[tex]\frac{2}{0.25}=x[/tex]
8 = x
So, remembering that the amount of time it had been raining, x, is expressed in hours, the time it took until 2 inches of rain fell is 8 hours.

Use a calculator to convert 0.0625 into fraction which is [tex]\frac{1}{16}[/tex]
Multiply [tex]\frac{1}{4}[/tex] by 3 = [tex]\frac{1}{64}[/tex]

length: 2 cubeswidth: 1 cubeheight: 2 cubesvolume: 4 cubesStep-by-step explanation:
We assume in this context that a "1/4 unit cube" is a cube that is 1/4 unit on a side. When the "unit" is "inches", then the "1/4 unit cube" is a cube that is 1/4 inch on a side.
It should not take too much thought to realize that a dimension that is 1/2 = 2/4 inches will be 2 cubes long. A dimension that is 1/4 inch will be 1 cube long.
Then the 1/2 by 1/2 by 1/4 prism will have dimensions in "cubes" of ...
2 cubes × 2 cubes × 1 cube
As with any rectangular prism volume calculation, the volume is the product of the dimensions:
V = LWH = (2)(1)(2) = 4 . . . cubes
_____
For this prism, it should not be too difficult to see that if you stack 2 smaller cubes on top of two smaller cubes, the overall dimensions of that will be 1/2 inch wide by 1/2 inch high by 1/4 inch deep.
_____
Additional comment
Which dimensions you call length, width, and height are irrelevant, as each is interchangeable with any other in the formula for volume. Here, I have elected to call height the vertical dimension, length the left-right horizontal dimension, and width the front-back dimension. You are welcome to choose an assignment of names to dimensions that suits your taste (or that of your grader).
