You purchase a 189-day, $1000 U.S. Treasury bill at 4.19% discount. On the date of maturity, you will receive $1000. How much interest does the U.S. Government pay to you on the date of maturity?
Answer:
The government paid an interest of $41.9, which is 4.19%
Step-by-step explanation:
Given the 189-day, $1,000 U.S Treasury bill is purchased at a discount of 4.19%, this means that:
It was purchased at a discount of:
4.19% of $1000
= (4.19/100) × 1000
= $41.9
Purchase price = $1000 - $41.9 = $958.1
Because the treasure is sold for $1000 on maturity day, that means the government paid an interest of $41.9, which is 4.19%

Write the equation in slope intercept form: passing through the x-axis at x=3 and passing through the y-axis at y= -5
Answer:
[tex]y=\frac{5}{3}x-5[/tex]
Step-by-step explanation:
Slope-intercept:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept. We know that the line passes through the y-axis at -5, so this is the y-intercept (where x is equal to 0). Insert this into the equation:
[tex]y=mx-5[/tex]
With the given information, we can form two points:
[tex](3,0)(0,-5)[/tex]
The first one is the x-intercept and the second the y-intercept. Use these to find the slope:
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}[/tex]
Rise over run is the change in the y-axis over the change in the x-axis, otherwise known as the slope. Insert the appropriate values:
[tex](3_{x1},0_{y1})\\(0_{x2},-5_{y2})\\\\\frac{-5-0}{0-3}[/tex]
Solve:
[tex]\frac{-5-0}{0-3}=\frac{-5}{-3}[/tex]
Note that both the numerator and denominator are negatives. Two negatives make a positive, so:
[tex]\frac{5}{3}[/tex]
The slope is [tex]\frac{5}{3}[/tex]
Insert into the equation:
[tex]y=\frac{5}{3}x-5[/tex]

find the slope of the line passing through (-9,-6) and (-4,5)
Answer:
11/5
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (5 - -6)/(-4 - -9)
= (5+6)/( -4+9)
= 11/5
Let's find the slope using the graphing method.
First set up a coordinate system like I have done below.
Now, graph each ordered pair.
Let's call (-9, -6) point A and (-4, 5) point B.
Now remember that the slope or m is equal
to the rise over run from point A to point B.
To get from point A to point B, we rise 11 units and run 5 units.
So our slope is 11/5.
Carson needs 3 quarts of water to make fruit punch, but has only a l-cup measuring cup.
She knows there are 2 cups in 1 pint, and 2 pints in 1 quart.
Use the drop-down menus to explain how Carson can find the number of cups of water she
needs to make the punch.
Please help!!!
Answer:
Cups of water she needs to make the punch is 12.
Step-by-step explanation:
Amount of water Carson need to make fruit punch = 3 quarts
2 cups is 1 pint
2 pints is 1 quart
1 pint = 1/2 quarts
2 cups is 1 pint which is 1/2 quarts
So, 1 cup:
1 cup is 1/2 times 2 quarts
1 quart is 1 times 2 times 2 cups equals 4 cups
So, 3 quarts equals 3 times 4 cups which equals 12 cups.
So it is 12 cups.
Cups of water she needs to make the punch is 12.
What is unit conversion?
A unit conversion expresses the same property as a different unit of measurement.
Given that, Carson needs 3 quarts of water to make fruit punch, but has only an l-cup measuring cup.
She knows there are 2 cups in 1 pint, and 2 pints in 1 quart.
Amount of water Carson need to make fruit punch = 3 quarts
2 cups is 1 pint
2 pints is 1 quart
1 pint = 1/2 quarts
2 cups is 1 pint which is 1/2 quarts
So, 1 cup:
1 cup is 1/2 times 2 quarts
1 quart is 1 times 2 times 2 cups equals 4 cups
So, 3 quarts equals 3 times 4 cups, which equals 12 cups.
Hence, she need 12 cups.

Answer:
assosiative property
A calculator company plans to sell two models of graphing calculators that cost $100 and $150, respectively. The $100 model yields a profit of $40 and the $150 model yields a profit of $50. The company estimates that the total monthly demand will not exceed 250 units. What are the number of units of each model should be stocked in in order to maximize profit, assuming that the merchant does not want to invest more than $30,000 in inventory?
Answer:
The quantity of the first model is 150 and the second model is 100 that maximize the profit.
Step-by-step explanation:
Let the quantity of first model = x
Let the quantity of second model = y
The cost of the first model = $100
The cost of the second model = $150
Total number of models = 250 units
Total amount to spend on units = $30000
Now form the equations.
x + y = 250
100x + 150y = 30000
Now solve for the x and y.
x = 250 – y
Now insert this value in the 100x + 150y = 30000.
100(250 –y) + 150y = 30000
25000 – 100y + 150y = 30000
50y = 30000 – 25000
50y = 5000
Y = 100
Now insert the Y in x + y = 250
x = 250 – y
x = 250 – 100
x = 150
Therefore, the first model is 150 units and the second model is 100 units that maximize the profit.

The length of a rectangle is five inches more than four times it’s width if the perimeter of the rectangle is 90 inches , find it’s dimensions
Answer:
length = 37 incheswidth = 8 inchesStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 90 inches
The statement
The length of a rectangle is five inches more than four times it’s width is written as
l = 5 + 4w
Substitute this expression into the above formula and solve for the width
That's
90 = 2(5 + 4w) + 2w
90 = 10 + 8w + 2w
10w = 90 - 10
10w = 80
Divide both sides by 10
w = 8
Substitute this value into l = 5 + 4w
That's
l = 5 + 4(8)
l = 5 + 32
l = 37
Therefore we have
length = 37 incheswidth = 8 inchesHope this helps you

A and B have certain number of mangoes. A says to B, " If you give me 10 of your mangoes, I will have twice as many as left with you." B replies, "If you give me 10 of your mangoes, I will have thrice the number of mangoes left with you. Find the original number of mangoes each had.
Answer:
A had 22 mangoes, B had 26 mangoes
Step-by-step explanation:
We can write the following system:
A + 10 = 2(B - 10) -- Equation 1
3(A - 10) = B + 10 -- Equation 2
A + 10 = 2B - 20 → A = 2B - 30 -- Equation 3 (Simplify Equation 1)
3(2B - 30 - 10) = B + 10 -- Equation 4 (Substitute 3 into 2)
3(2B - 40) = B + 10
6B - 120 = B + 10
5B = 130
B = 26 -- (Solve for B in Equation 4)
A = 2 * 26 - 30 = 22 -- (Substitute B = 26 into Equation 3)

Joshua spins a spinner twice. The spinner consists of 3 equally spaced colors, Red, Blue, and Yellow. What is the probability that the spinner will stop on green and then yellow? ASAP
Answer:
[tex]\dfrac{1}{9}[/tex]
Step-by-step explanation:
Given a spinner with 3 equally spaced colors Red, Blue, Yellow.
The colors are equally spaced, therefore probability of each color must be same.
i.e. Probability of occurrence of any one color in one spin is [tex]\frac{1}{3}[/tex].
To find:
Probability that spinner will stop one green in first spin and yellow in the second spin = ?
Solution:
As all the colors are equally likely to occur, so
Probability of green color in the first spin, P(G) = [tex]\frac{1}{3}[/tex]
Probability of yellow color in the second spin, P(Y) = [tex]\frac{1}{3}[/tex]
As we can observe that occurrence of any color in the second round of spin is not dependent on the color occurrence in the first spin, therefore these are the independent events.
P(G and Y) = P(G) [tex]\times[/tex] P(Y)
[tex]\Rightarrow P(G\ and\ Y) = \dfrac{1}{3} \times \dfrac{1}{3}\\\Rightarrow P(G\ and\ Y) = \bold{\dfrac{1}{9}}[/tex]
Therefore, the required probability is
[tex]\dfrac{1}{9}[/tex].

Erik and Caleb were trying to solve the equation: 0=(3x+2)(x-4) Erik said, "The right-hand side is factored, so I'll use the zero product property." Caleb said, "I'll multiply (3x+2)(x-4) and rewrite the equation as 0=3x^2-10x-8 Then I'll use the quadratic formula with a=3, b=-10, and c=-8. Whose solution strategy would work? A) Erik B) Caleb C) Both D) Neither
Answer:
C) Both
Step-by-step explanation:
The given equation is:
[tex]0=(3x+2)(x-4)[/tex]
To solve the given equation, we can use the Zero Product Property according to which if the product A.B = 0, then either A = 0 OR B = 0.
Using this property:
[tex](3x+2) = 0 \Rightarrow \bold{x = -\frac{2}{3}}\\(x-4) = 0 \Rightarrow \bold{x = 4}[/tex]
So, Erik's solution strategy would work.
Now, let us discuss about Caleb's solution strategy:
Multiply [tex](3x+2)(x-4)[/tex] i.e. [tex]3x^2-12x+2x-8[/tex] = [tex]3x^2-10x-8[/tex]
So, the equation becomes:
[tex]0=3x^2-10x-8[/tex]
Comparing this equation to standard quadratic equation:
[tex]ax^2+bx+c=0[/tex]
a = 3, b = -10, c = -8
So, this can be solved using the quadratic formula.
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\dfrac{-(-10)\pm\sqrt{(-10)^2-4\times3 \times (-8)}}{2\times 3}\\x=\dfrac{-(-10)\pm\sqrt{196}}{6}\\x=\dfrac{10\pm14}{6} \\\Rightarrow x= 4, -\dfrac{2}{3}[/tex]
The answer is same from both the approaches.
