Deshaun invested in a savings bond for 4 years and was paid simple interest at an annual rate of 2%. The total interest that he earned was $160. How much did he invest?
For a Simple Interest of $160, the amount that he invested is $2000.
Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
Given:
Simple Interest (S.I.) = $160
Rate of Interest (R) = 2%
Time Period (T) = 4 Years
Let the Principal Amount be $P
We know,
[tex]S.I. =\frac{P*R*T}{100}[/tex]
Putting the given values in the formula, we get:
[tex]S.I. =\frac{P*R*T}{100}\\S.I. =\frac{P*2*4}{100} =\frac{P*8}{100}\\ 160 =\frac{P*8}{100} \\P = \frac{160*100}{8} =\frac{16000}{8} = 2000[/tex]
Hence, He Invested $2000

Answer:
$2,000
Step-by-step explanation:
Simple Interest Formula
[tex]\large\boxed{\sf I = Prt}[/tex]
where:
I = Total interest accrued.P = Principal.r = Interest rate (in decimal form).t = Time (in years).Given values:
I = $160r = 2% = 0.02t = 4 yearsSubstitute the given values into the formula and solve for P:
[tex]\implies \sf 160=P \cdot 4 \cdot 0.02[/tex]
[tex]\implies \sf 160=0.08P[/tex]
[tex]\implies \sf P=\dfrac{160}{0.08}[/tex]

Therefore, the amount Deshaun invested was $2,000.
You are on the prom decorating committee and are in charge of buying balloons. you want to use both latex and mylar balloons. The latex balloons cost $.10 each and the mylar balloons cost $.50 each. You need 125 balloons and you have $32.50 to spend. how many of each can you buy?
I can buy 75 latex balloons and 50 mylar balloons.
This is a problem from an algebraic equation. We can solve this problem by following a few steps.
We need 125 balloons. Let's assume we have to purchase x latex balloons.
So, mylar balloons are ( 125 - x ).
Our total budget is $32.50.
The cost of x latex balloons is ($.10 × x) = $.10x , as the latex balloons cost $.10 each.
The cost of ( 125- x) mylar balloons is $[( 125- x) × 0.50] , as the mylar balloons cost $.50 each.
So the total cost is,
$[( 125- x) × 0.50] + $.10x = 32.50
Now, we have to solve this equation, Let's simplify it.
62.50 - 0.50x + .10x = 32.50
Or, 62.50 - 0.40x = 32.50
Or, -0.40x = 32.50 - 62.50 [ deduce 62.50 from both side ]
Or, -0.40x = -30 [ we should devide both sides 0.40 ]
Or, x = 30/0.40 = 75
So, the number of latex balloons is 75. Therefore, the number of remaining mylar balloons is ( 125 - 75) = 50

INFORMATION:
We have the next rhombus
And we must find the measure of
Knowing that DB = 10, BC = 13, and m∠WAD = 25°
STEP BY STEP EXPLANATION:
To find all measures, we need to use properties or the rhombus:
- DA: To find DA we need to know that all sides of the rhombus are equal. So, if BC measures 13, then DA measures 13 too.
- BW: To find BW we need to know that in a rhombus, diagonals bisect each other at right angles. That means, diagonals intersect in the middle. So, if DB = 10, then BW will be half of BD. BW = 10/2 = 5.
- WC: We can find it as one of the legs of the right triangle formed by BW, BC and WC. Where, BC is the hypotenuse.
[tex]\begin{gathered} 13^2=5^2+WC^2 \\ WC=\sqrt{13^2-5^2} \\ WC=12 \end{gathered}[/tex]So, WC = 12.
- Angle BAC: To find this angle, we need to use that the interior triangles formed in the interior of the rhombus are congruent. So, angle BAC is congruent with the angle DAC. Then, BAC = 25°.
ANSWER:
DA = 13
BW = 5
WC = 12
BAC = 25 degrees

Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost 20$ . The items she bought cost a total of 160 before tax was added. What was the cost of each sweater?
A
$20\$ 20$20
Using simple linear equation we calculate the cost of a sweater as $35 .
A linear polynomial over a field, from which the coefficients are taken, can be equalised to zero to produce a linear equation.
The numbers that, when used to replace the unknowns in such an equation, result in the equality, are the solutions.There is just one possible answer when there is only one variable (providing that. The term "linear equation" frequently alludes indirectly to this specific situation, in which the variable is appropriately referred to as the "unknown."Let the cost of each sweater be x.
Cost of the skirt = $20
Let us form a linear equation to calculate the required cost
4x + 20 = 160
solving we get :
x = 35
Therefore the cost of a skirt is $35.

write the equation of a circle given the center (2, 9) and radius r = 3
Answer: x^2 + y^2 - 4x + 18y = 76 = 0
The center of the circle given is (2, 9)
radius = r
The equation of a circle for a given point is
(x - h)^2 + (y - k)^2 = r^2
Where h = 2, and y = 9
(x - 2)^2 + (y - 9)^2 = 3^2
Expand the parentheses
(x - 2) (x - 2) + (y - 9) (y - 9) = 9
(x - 2) (x - 2 ) = x* x - 2*x - 2*x + 2* 2
= x^2 - 4x + 4
(x - 2) (x - 2) = x^2 - 4x + 4
(y - 9) (y - 9) = y*y - y*9 - 9*y + 9*9
= y^2 - 18y + 81
(y - 9) (y - 9)= y^2 - 18y + 81
Therefore, the equation becomes
x^2 - 4x + 4 + y^2 - 18y + 81 = 9
Re-arrange the equation
x^2 + y^2 - 4x - 18y + 4 + 81 = 9
x^2 + y^2 - 4x - 18y = 9 - 81 - 4
x^2 + y^2 - 4x - 18y = -76
x^2 + y^2 - 4x - 18y + 76 = 0
The equation of a circle given the center (2, 9) and radius 3 is x^2 + y^2 - 4x + 18y = 76 = 0
Answer:
The equation of a circle given the center (2, 9) and radius 3 is x^2 + y^2 - 4x + 18y = 76 = 0

write an expression on in terms of n for the nth term of the sequence
An expression, in terms of n, for the nth term of this arithmetic sequence is aₙ = 23 - 4n.
What is an arithmetic sequence?An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.For the second term, we have:
a₂ = a₃ - d
a₂ = 11 - (-4)
a₂ = 11 + 4
a₂ = 15.
For the first term, we have:
a₁ = 4 + second term
a₁ = 4 + 15
a₁ = 19
Substituting the given parameters into the formula, we have;
aₙ = a₁ + (n - 1)d
aₙ = 19 + (n - 1)(-4)
aₙ = 19 - 4n + 4
aₙ = 23 - 4n

Equation of the line is y = -(1/3)x+5
The figure shows a straight line of which two points and thereby the slope can be found out.
Equation of a line is in the slope-intercept form is,
y = mx +c,
where m is the slope of the line and c is the y-intercept of the line.
From the figure, two points on the line are, (0,5) and (3,4).
Then slope = (4-5)/(3-0)
= -1/3
Now y-intercept, c is the y-co-ordinate when x = 0.
From the figure, when x = 0, y = 5
So y-intercept, c = 5.

The equation of line is y = -9.
What is a equation of line?These lines are written in the form y = mx + b, where m is the slope and b is the y-intercept. We know from the question that our slope is 3 and our y-intercept is –5, so plugging these values in we get the equation of our line to be y = 3x – 5.
Given that,
(1, -9) = ( [tex]x_{1}, y_{1}[/tex])
(-3, -9) = [tex](x_{2},y_{2})[/tex]
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

(7x+1)°
Answer:
54 + (7x + 1) + 90 = 180° (sum of angles in triangle=180)
7x = 35
x = 5
Answer:
x = 5
Step-by-step explanation:
Geometry TheoryThis question deals with a right-angled triangle. The sum of the angles in a triangle is equal to 180 degrees. A right angle is equal to 90 degrees which means that the other two angles must equal to 90 degrees as well.
AlgebraForm the equation.
( 7x + 1 ) + 54 + 90 = 180;
Subtract 90 from both sides.
7x + 1 + 54 + 90 - 90 = 180 - 90;
7x + 1 + 54 = 90;
Simplify left-hand side.
7x + 55 = 90;
Subtract 55 from both sides.
7x + 55 - 55 = 90 - 55;
7x = 35;
Divide both sides by 7.
x = 35 / 7;
x = 5;

Step-by-step explanation:
f(3) means what is the value of f(x) when x = 3
substitute x = 3 into f(x)
f(3) = 10(3) + 13 = 30 + 13 = 43
similarly for x = - 8
f(- 8) = 10(- 8) + 13 = - 80 + 13 = - 67
given f(x) = 10x + 13 and f(x) = 53 , equate the right sides
10x + 13 = 53 ( subtract 13 from both sides )
10x = 40 ( divide both sides by 10 )
x = 4
