After 4 years, $3,006 deposited in a savings account with simple interest had grown to a total of $3,967.92. What was the interest rate?
Answers
Answer:
So interest rate is 8% per annum
Step-by-step explanation:
Principal amount = $3,006
Amount at end = $3,967.92
Time = 4yrs
interest money = ($3967.92 - $3006)
also equal to = 4 * (x/100) * $3,006
Where x is the interest rate per annum
So, 4 * (x/100) * $3,006 = ($3967.92 - $3006)
x = 8%
So interest rate is 8% per annum
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11 A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10 How much does a liter of milk cost, and how much does a loaf of bread cost?
Answers
Answer:
A liter of milk cost $0.75 and a loaf of bread cost $1.75
Step-by-step explanation:
Let the liters of milk by represented by m
Let the loaves of bread by represented by b
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11
3m + 5b = 11...... Equation 1
A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10
4m + 4b = 10.... Equation 2
Combining the Equations
3m + 5b = 11...... Equation 1
4m + 4b = 10.... Equation 2
We solve using the Elimination method
Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m
12m + 20b = 44..... Equation 3
12m + 12b = 30....... Equation 4
Substract Equation 4 from Equation 3
8b = 14
b = 14/8
b = $1.75
Solving for m
3m + 5b = 11...... Equation 1
3m + 5($1.75) = 11
3m + $8.75 = $11
3m = $11 -$ 8.75
3m =$ 2.25
m =$ 2.25/3
m = $0.75
Therefore,
a liter of milk cost $0.75 and a loaf of bread cost $1.75

Its my math question
Answers
Answer:
251028.928
Step-by-step explanation:
i used a calculator
The result of the expression 7 x 8(9 + 8) - 6 x 7 + 2 (77 x 8) - 7 + 1092 (2010 x 0.1134) + 17 - 27 will be 251028.928 .
Given , expression 7 x 8(9+8) - 6 x 7 + 2(77 x 8) - 7 + 1092(2010 x 0.1134) + 17 - 27.
Apply BODMAS to solve the expression.
B = Bracket
O = of
D = Division
M = Multiplication
A = Addition
S = Subtraction
Following the same order,
7 x 8(9+8) - 6 x 7 + 2(77 x 8) - 7 + 1092(2010 x 0.1134) + 17 - 27
= 952 - 42 + 1232 - 7 + 248903.928 + 17 - 27

Yes this is a real question please help
Answers
Answer:
the speed is 20 m/s
Step-by-step explanation:
The computation of the speed is as follows
As we know that
Speed = Distance ÷ time
where,
Distance is 420 meters
And, the time is 21 seconds
So, the speed is
= 420 ÷ 21
= 20 m/s
hence, the speed is 20 m/s

There is a spinner with 12 equal areas, numbered 1 through 12. If the spinner is spun
one time, what is the probability that the result is a multiple of 5 and a multiple of 2?
Answers
Answer:
1/12
Step-by-step explanation:
There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.

K is -12/5
k is also 28/5
Step-by-step explanation:
Here, we want to solve the equation
|5k-8| = 10(2)
5k-8 = 20
5k = 20 + 8
5k = 28
k = 28/5
or
5k-8 = -20
5k = -20 + 8
5k = -12
k = -12/5

Three partners x,y and z contribute an amount of ksh 1400000 for an investment .The profit from the investment is to be shared based on the contribution of each.A profit of ksh 250000 after one month.If x got sh 60000, y got 110000 and the remainder was Z .Calculate the ratio of the contribution
Answers
Answer:
The ratio of the contribution x:y:z is 6:8:11
Step-by-step explanation:
Firstly, we need to know the amount in which Z got
That will be 250,000-x-y
= 250,000- 60,000 - 110,000 = 80,000
So the ratio of the contribution in x:y:z will be;
60,000:110,000:80,000
= 6:11:8
