Last year, Yoko had $10,000 to invest. She invested some of it into an account that paid 10% simple interest per year, and she invested the rest in an account that paid 6% simple interest per year. After one year she received a total of $640 in interest. How much did she invest in each account?
Final answer:
At 10% interest, $1 000 was invested.
At 6% interest, $9 000 was invested.
Let "x" be the amount invested at 10%. The annual interest for this investment would be $ 0.1x
Now, the investment at 6% is (10 000 - x), and it would have an annual interest of 0.06(10 000 - x)
We will use the following equation to solve for this
[tex]interest_1+interest_2=totalinterest[/tex]interest 1 = 0.1x
interest 2 = 0.06(10 000 - x)
total interest = 640
Substitute these values
[tex]interest_1+interest_2=totalinterest[/tex][tex]0.1x+0.06(10000-x)=640[/tex]Solve for x
[tex]0.1x+0.06(10000-x)=640[/tex][tex]0.1x-0.06x=640-\lbrack(0.06)(10000)\rbrack[/tex][tex]0.04x=640-600[/tex][tex]0.04x=40[/tex]Divide both sides by 0.04
[tex]\frac{0.04x}{0.04}=\frac{40}{0.04}[/tex][tex]x=1000[/tex]Since the investment at 6% is equal to 10000-x,
[tex]interest_2=10000-x[/tex][tex]=10000-1000[/tex][tex]=9000[/tex]Final answer:
At 10% interest, $1 000 was invested.
At 6% interest, $9 000 was invested.
To check,
[tex]0.1x+0.06(10000-x)=640[/tex][tex]0.1(1000)+0.06(10000-(1000))=640[/tex][tex]640=640[/tex]The sum of two numbers is 27. Twice the smaller number plus 3 times the larger number is 70. Find the numbers.
I’m stuck on this please help :(
Answer:
The smaller number is 11 and the larger number is 16.
Step-by-step explanation:
Let x = smaller number and y = larger number. The sum of these numbers is 27, so we can make the equation x + y = 27. Twice the smaller number (2x) plus three times the larger number (3y) is 70, so we can also make the equation 2x + 3y = 70.
Now, let's take a look at that first equation, x + y = 27. Let's isolate y on one side, giving us y = -x + 27. Now, we can replace y in the second equation with that value, which will allow us to solve for x.
2x + 3y = 70
2x + 3(-x + 27) = 70
2x - 3x + 81 = 70
-x + 81 = 70
-x = -11
x = 11
So, the smaller number is 11. Again, our original equation is x + y = 27. We can now replace x with 11.
11 + y = 27
y = 16
The larger number is 16. If you have any questions or found that really confusing, let me know and I'll try to clarify for you. :)

As per the question statement, a company XYZ know that replacement times for the DVD players it produces are normally distributed with a mean of 10.5 years and a standard deviation of 1.8 years and we are supposed to tell the probability that a randomly selected DVD player will have a replacement time of less than 4.9 years.
Let "z" be the probability
z = (X - μ) / σ, where X = data, μ = mean, σ = standard deviation
z = (10.5 - 4.9) / 1.8
z = 0.3111 or 31.11%
Hence, the probability that a randomly selected DVD player will have a replacement time of less than 4.9 years is 31.11 % or 0.3111

0 0.217 + ? = 456.3
Answer:
456.083
Step-by-step explanation:
Use basic algebra to solve this problem:
0.217 + x = 456.3 (x just means an unknown value)
Subtract 0.217 from both sides. When you do this, it cancels out on the left side. REMEMBER: whatever you do to one side, you MUST do it to the other.
0.217 - 0.217 + x = 456.3 - 0.217
x = 456.083
0.217 + 456.083 = 456.3

A motorboat traveling 310 km in five hours going upstream and 736 km in eight hours going down stream what is the rate of the boat in Stillwater and what is the rate of the current
Solution
For this case we can create the following notation
B= velocity of boat
S= velocity of stream
Relative to the bank, the speed upstream is B-S.
The speed downstream is B+S.
And we can create the following equations:
(B-S)*5= 310
(B+S)*8= 736
We can solve for B and S and we have:
5B -5S = 310
8B+ 8S= 736
B= (310+5S)/5= 62+ S
Replacing in the second equation we got:
8(62+S) + 8S= 736
496 + 8S + 8S = 736
16S= 240
S= 240/16= 15
B= 62+15= 77
Then the velocity of current is 15km/hr and for the boat 77km/hr

The general formula to calculate the simple interest is given to be:
[tex]I=P\times R\times T[/tex]where:
[tex]\begin{gathered} I=\text{ Simple Interest} \\ P=\text{ Loan Amount} \\ R=\text{ Rate in decimals} \\ T=\text{ Number of time periods (yearly)} \end{gathered}[/tex]To adjust for daily time periods, we will divide the rate by 365. Therefore, we have the following parameters:
[tex]\begin{gathered} P=300 \\ R=\frac{4}{100\times365}=\frac{1}{9152} \\ T=60 \end{gathered}[/tex]Note: We are working with the assumption that the rate is annual, although not clearly stated.

[tex]\sin (\frac{11\pi}{36}-\frac{\pi}{18})=\sin \frac{11\pi}{36}\cos \frac{\pi}{18}-\cos \frac{11\pi}{36}\sin \frac{\pi}{18}[/tex]which is the same given expression. Then, we have that
[tex]\sin (\frac{11\pi}{36}\frac{\pi}{18})=\sin (\frac{11\pi}{36}-\frac{2\pi}{36})=\sin (\frac{11\pi}{36}-\frac{2\pi}{36})=\sin \frac{9\pi}{36}=\sin \frac{\pi}{4}[/tex]Then, the answer is:

How is solving a multistep inequality the same as solving a multistep equation? How is it different?
You utilize PEMDAS (parentheses, exponents, multiplication, division, add, subtract) to solve a multi-step equation, and you use the same to solve a multi-step inequality. But inequalities are tough since you have to reverse the sign when multiplying or dividing by a negative integer. And although though a multi-step equation often has 1 or 2 solutions, if you write it as x= #, you'll get the same result but with an inequality sign (or signs).
Hence the above is the difference between solving a multistep inequality and multistep equation.

What is profit?If the selling price is higher than the cost price, the difference between the two is referred to as profit. If the selling price is less than the cost price, the difference is referred to as the loss.Given this,
The seller's cost price is 210 dollars.
The seller's selling price is 279.30$.
We know that ,
Profit = selling price - cost price.
so, Profit = 279.30$ - 210$

#!). Two planes leave New York at 10am, One heading for Europe at 600mph and one heading in the opposite direction at 150mph. At what time will they be 900 miles apart? How far has each traveled?
Speed = Distance / time
Distance = Speed x time
In t hours, first plane travels = 600 t miles
In t hours, the second plane travels =150 t miles
After t hours the distance between the two planes is:
(600t+150t)= 750t ( since both travel in opposite directions)
When the distance is 900 miles:
750t= 900
Solve for t:
t= 900/750
t= 1.2 hours
After 1.2 hours.
1.2 x 60 = 72 minutes = 60 +12 = 1 hour and 12 minutes
Since both leave at 10 pm:
10am + 1 hour and 12 minutes : 11:12 am
They will be 900 miles apart at 11:12 am
Each one traveled:
Plane 1:
Distance: Speed x time = 600 mph x 1.2 = 720 miles
Plane 2:
