Joseph invested $6,700 in an account paying an interest rate of 5.2% compounded
quarterly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $13,950?
Answer:
it will take 14 years approximately
Step-by-step explanation:
To get this, we use the compound interest formula
We have this as:
A = P ( 1 + r/n)^nt
where ;
A is the amount after the stipulated time = 13,950
P
is the amount deposited = 6,700
r is the rate = 5.2% = 5.2/100 = 0.052
n is the number of times interest is compounded yearly = 4 (quarterly is every 3 months)
t is what we want to calculate
13,950 = 6,700 ( 1 + 0.052/4)^4t
2.082 = 1.013^4t
ln 2.082 = 4t ln 1.013
ln 2.082/ln 1.013 = 4t
56.78 = 4t
t = 56.78/4
t = 14 years

Answer:
no your answer is wrong. the answer is 15.6
Step-by-step explanation:
it is a 30-60-90 degree triangle and as per the property ..
the side opposite to 30 degree angle is half of hypotenuse( I. e half of 18 that is 9)
the side opposite to 60 degree angle is √3/2 the hypotenuse.
that is √3/2 * 18
that is √3 * 9
that is 1.73 multiplied by 9 .....(as value of √3 is 1.73)
that is 15.57
rounding it to the nearest tenth it becomes 15.6
answer is 15.6 not 20.1

Find the common ratio r for the geometric sequence and use r to find the next three terms. Enter your answer to four decimal places if necessary. 100, -40, 16, -6.4, The Common Ratio The next three terms are
Answer: The next three terms =2.56, - 1.024 and 0.4096
Step-by-step explanation:
Common Ratio of a Geometric sequence, R is calculated as
=a2/a1 = -40/100=-0.4
or a3/a2=16/ -40 = -0.4
such that the next three terms are
5th term = -6.4 x -0.4=2.56
6th term= 2.56 x -0.4 =-1.024
7TH term= -1.024 x -0.4=0.4096

What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Area of rectangle= 56 square yards.
let the width be x.
So, length = 3x+ 2
So, Area of rectangle= 56 square yards.
length x width = 56
x(3x+2 )= 56
3x² + 2x -56= 0
3x² + -56= 0
3x( x - 4 ) + 14 ( x - 4) = 0
(3x+ 14) (x- 4) = 0
x= 4, -14/3
Hence, the width is 4 and length is 14 yards.

(b). 27
Step-by-step explanation:
The sum of exterior angles of any polygon is 360°
2x° +56° + 4x° + 57° + 85° = 360°
6x° + 198° = 360°

In a shipment of shirts to a clothing store, 2/5 of the shirts are blue and 3/10 of the shirts are red. If there are 20 shirts in the shipment, how many shirts are either blue or red?
Answer: 14
Step-by-step explanation:
Fraction of blue shirts = 2/5
Fraction of red shirts = 3/10
Number of shirts in the shipment = 20
The number of shirts that are either blue or red will be:
= (2/5 + 3/10) × 20
= (4/10 + 3/10) × 20
= 7/10 × 20
= 14
The number of shirts that are either blue or red is 14

Find the area of a circle with diameter 31.6 cm, both in terms of p and to the nearest tenth. Use 3.14 for p.
Your answer:
A = 249.64p cm2» 783.9 cm2
A = 63.2p cm2» 198.4 cm2
A = 31.6p cm2» 99.2 cm2
A = 998.56p cm2» 3135.5 cm2
Answer:
Option (1)
Step-by-step explanation:
Formula to get the area of a circle is given by,
Area = πr²
Here r = radius of the circle
Since, Radius of a circle = [tex]\frac{\text{Diameter}}{2}[/tex]
Therefore, Radius of the circle with diameter = 31.6 cm will be,
Radius = [tex]\frac{31.6}{2}[/tex]
= 15.8 cm
Now Area of the circle = π(15.8)²
= 249.64π cm²
= 783.87 cm²
≈ 783.9 cm²
Therefore, Option (1) will be the correct option.

Hi there! Your answer is x = -2, y = -9/2
In coordinate point, we can write (-2,-9/2)
Please see the explanation below for a clear understand about the problem.
Any questions about the answer, feel free to ask in comment! :)
Step-by-step explanation:
Goal
Solve the system of equations by substitution method.Given
System of Equations[tex]\begin{cases} x=2y+7 \Longrightarrow (1)\\ 3x-2y=3 \Longrightarrow (2) \end{cases}[/tex]
Step 1
Since our x-term is the subject in the first equation, we can simply substitute x = 2y+7 in the second equation.Substitute x = 2y+7 in the second equation.
[tex]3x-2y=3\\3(2y+7)-2y=3[/tex]
We do this so we can solve for the y-term without any problems. (We need to get rid of a variable if there are more than one variable.)
Then we distribute/expand 3 in the expression.
[tex]6y+21-2y=3\\4y+21=3[/tex]
Step 2
Solve the equation for y-termTo solve the equation, we have to isolate the term that we want. For this scenario, we want to know the value of y-term. Therefore, we isolate y-term.
[tex]4y=3-21\\4y=-18\\y=-\frac{18}{4} \\y=-\frac{9}{2}[/tex]
Finally! we know the value of y which is -9/2. But we are not done yet!
Step 3
Substitute the y-value in any given equations.After we solve the equation, we have to substitute the value in any given equations. No need to substitute the value in both equations! Choose an equation to substitute the value in.
For this, I will be choosing an equation with less coefficients which is the first equation.
[tex]x=2y+7[/tex]
Substitute y = -9/2 in the equation.
[tex]x=2(-\frac{9}{2})+7\\x=-9+7\\x=-2[/tex]
We should get x = -2 as the answer. This is our last step for finding an answer. The next few steps are going to be how to check the answer for system of equations. Note that next few steps are optional. If you are not certain that the answer is wrong or right, it is highly advised to check the answer before jumping to a conclusion!
Optional Steps - Answer Check
To check the answer, we can simply substitute both x-value and y-value in any given equations. You can either choose only a single equation to substitute in ONLY if you are certain/sure that the answer is likely correct. Substituting in both equations are recommended for beginners.
Step 3
Substitute x = -2 and y = -9/2 in the system of equations.Step 3.1
Substitute in x = 2y+7[tex]x=2y+7[/tex]
From x = -2 and y = -9/2
[tex]-2=2(-\frac{9}{2} )+7[/tex]
Cancel 2 out.
[tex]-2=-9+7\\-2=-2[/tex]
As you can see, both sides are equal. That means the equation is true for x = -2 and y = -9/2.
Step 3.2
Substitute in 3x-2y = 3[tex]3x-2y=3[/tex]
Substitute x = -2 and y = -9/2 in the equation.
[tex]3(-2)-2(-\frac{9}{2})=3\\-6+\frac{18}{2}=3\\-6+9=3\\3=3[/tex]
Since both equations are true for x = -2 and y = -9/4. We can conclude that:
[tex]\huge\sf{x = -2 \ and \ y = -\frac{9}{2} \ are \ the \ solutions \ to \ the \ system \ of \ equations.}[/tex]
Hence, the answer is x = -2 and y = -9/2.

Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?
Answer:
angle 1 is = 124 angle 2 is = 56
Step-by-step explanation:
supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.
