Answer:

$8,000 in Treasury bills

$7,000 in Treasury bonds

$5,000 in corporate bonds

Step-by-step explanation:

Let the amount to be invested in treasury bills be $x , the amount to be invested in treasury bonds be $y

From the question, we understand that the amount she will invest in corporate bonds will be $3000 less than the amount in treasury bills;

So mathematically, this will be $(x - 3000)

So therefore, the amount invested in each will be;

x + y + x-3000 = 20,000

2x + y = 20,000 + 3000

2x + y = 23,000 ••••••••(i)

Let’s now work with the simple interests;

For treasury bills;

5% = 5/100 * x = 5x/100

For Corporate bonds ;

10% = 10/100 * (x -3000) = (x-3000)/10

For Treasury bonds 7%

7% = 7/100 * y = 7y/100

Adding all gives the total interest;

5x/100 + 7y/100 + (x-3000)/10 = 1390

Multiply through by 100

5x + 7y + 10(x-3000) = 1390 * 100

5x + 7y + 10(x-3000) = 139,000

5x + 7y + 10x -30,000 = 139,000

15x + 7y = 139,000 + 30,000

15x + 7y = 169,000 •••••••••(ii)

So we have two equations to solve simultaneously;

From i, y = 23,000 - 2x

Put this into ii

15x + 7(23,000 -2x) = 169,000

15x + 161,000 - 14x = 169,000

x + 161,000 = 169,000

x = 169,000 - 161,000

x = $8,000

y = 23,000 - 2x

y = 23,000 - 2(8,000)

= 23,000 - 16,000 = $7,000

So the last investment amount is x-3000 = 8,000 -3,000 = $5,000

Answer:

The answer is -19.

Step-by-step explanation:

You have to substitute the x = 5 into the function :

[tex]g(x) = - 3x - 4[/tex]

[tex]g(5) = - 3(5) - 4[/tex]

[tex]g(5) = - 15 - 4[/tex]

[tex]g(5) = - 19[/tex]

Answer:

F

Step-by-step explanation:

F is the correct graph because the bottom is for minutes and if you drag your finger on the 1 minute you meet 45 which is how many gallon per minute. and if you go to 2 minutes you meet with 90 which is 45+45=90 and 45 is one minute and 90 is 2 minutes.

srry if that was complicated

Hope this helps you!

The graph which best represents the rate of discharge given is graph F.

It is given that discharge rate of a water hose is 45 gallons per minute.

We have to check which graph has a slope that best represents this rate.

What do you mean by discharge rate of water ?

Discharge rate of water is defined as the rate at which drainage water is released from a site.

As per the question ;

The rate of discharge = 45 gallons per minute

So,

We can say that ;

When x = 1 minute

y = 45 gallons

We can conclude that F is the correct graph because the x-axis is for minutes and if you check at time 1 minute you get 45 gallons at the y-axis which shows the no. of gallons per minute.

Thus , the graph which best represents the rate of discharge given is graph F.

6.1

Step-by-step explanation:

anything 5 and over you round to one, so .08 turns into .1 :) glad i could help

The given decimal number is rounded to the nearest tenth as 6.1.

The given decimal number is 6.08.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Here, in 6.08 digit in the hundredths place is 8, which is greater than 5.

So, the digit in the tens place increased by 1 and digits after tens place becomes zero.

That is, 6.10

Therefore, the given decimal number is rounded to the nearest tenth as 6.1.

Answer:

A) 7,950$, B) 7,963.73$, C) Since daily interest means that 6%/365 of 7500 will be added and compounded every day for the given amount of time(in this case, one year), while annual interest means that 6% of 7500 will be added and compounded yearly for the given amount of time(I'm this case, one year).

Step-by-step explanation:

Given the compound interest formula, A = P(1+r/n)^nt, where A = total amount(final amount), P = principle or amount of money deposited(starting amount), r = annual interest rate(percent interest in respect to t ; decimal = %/100), and n = conversion rate(number of times compounded per t; how much is it compounded)

t = time(time in respect to years ; how long it is compounded).

For A) A = 7500( 1 + 6%/365 ) ^ 365 = 7500(1 + 0.06/365) ^365 = 7500(1 + 0.00016438356..)^365= 7500(≈1.0001644^365) = 7500(100.01644%^365) = 7500(≈106.183%) = 7963.725 ≈ 7963.73$

For B) A = 7500( 1 + 6% ) ^ 1 = 7500(1 + 0.06) = 7500(1.06) = 7500(106%) = 7950$

C) this is because compounding something with a higher frequency leads to a different percentage (as n approaches infinity with time proportional to the annual rate, the ratio between the principle and total amount are proportional to e)

Answer:

$63.60

Step-by-step explanation:

4 board games are $15 each, multiply 4*15 = 60.

There is a 6% sales tax, so it is 6% extra. To calculate 6% as a decimal, divide it by 100, so 6/100 = 0.06. Now that it is 0.06 extra, you add 0.06 to 1.00 because 1.00 is the 100% of the price (the $60). So now it is 1.06 of the price. Multiply 60 * 1.06 and you get $63.60

Answer:

60.36 cents

Step-by-step explanation:

you have to times 60 by .6 then you get 36 and that is how much taxes cost.
