investment be worth $20,000? Show your work.
A = Pert
Answer:
32 years
Step-by-step explanation:
32 years
Step-by-step explanation:
fist find how much of 6750 is 6.25%
6750 * .0625 = 421.875
then use trial and error until u get the number u want
421.875 * 10 = 4218.75 + 6750 = 1096875 NO
421.875 * 20 = 84375 + 6750 = 151875 NO
421.875 * 30 = 12656.25 + 6750 = 19406.25 NO
421.875 * 31 = 13078.125 + 6750 = 19828.125 NO
421.875 * 32 = 13500 + 6750 = 20250 YES

Answer:
=90[tex]x^{2}[/tex]+2x+3
Step-by-step explanation:
Let's simplify step-by-step.
2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 − ( −6[tex]x^{2}[/tex] − 2x + 5 )
Distribute the Negative Sign:
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + − 1 ( − 6[tex]x^{2}[/tex] − 2x + 5 )
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + − 1( − 6[tex]x^{2}[/tex] ) + − 1 ( −2x ) + ( − 1 ) ( 5 )
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + 6[tex]x^{2}[/tex] + 2x + − 5
Combine Like Terms:
= 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 8 + 6[tex]x^{2}[/tex] + 2x + −5
= ( 2[tex]x^{2}[/tex] + 82[tex]x^{2}[/tex] + 6[tex]x^{2}[/tex] ) + ( 2x ) + ( 8 + − 5 )
= 90[tex]x^{2}[/tex] + 2x + 3

15. Find the force on an electron crossing a uniform magnetic field of intensity 0.5 T WILII
velocity of 106 ms-1. The charge carried by the electron is -1.6 x 10-19C.
Answer:
F = 8.48 x [tex]10^{-18}[/tex] N
Step-by-step explanation:
The force on an electron in a magnetic field can be determined by;
F = qvB Sin θ
where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.
Thus,
q = -1.6 x [tex]10^{-19}[/tex] C
v = 106 m/s
B = 0.5 T
θ = [tex]90^{o}[/tex]
So that,
F = 1.6 x [tex]10^{-19}[/tex] x 106 x 0.5
= 8.48 x [tex]10^{-18}[/tex] N
The force on the electron crossing the uniform magnetic field is 8.48 x [tex]10^{-18}[/tex] N.

Answer:
1) x=45
2) x=25
Step-by-step explanation:
1) I'm assuming that they're vertical angles and are equal
2x + 6 = 96
2x = 90
x = 45
2)
180 - 40 - 75= 65
4x + 15 + 65 = 180
4x + 80 = 180
4x = 100
x = 25

GHJ looks like it on 112 degrees.
IHJ is an acute angle so smaller than 90 degrees. I cant see the numbers there but I'm guessing its about 68 degrees.
GHJ + IHJ= 180
they should equal 180 degrees when added together.

What are the measures of angles P and S? ∠P = 20°; ∠S = 160° ∠P = 40°; ∠S = 140° ∠P = 140°; ∠S = 40° ∠P = 160°; ∠S = 20°
*see attachement for diagram
Answer:
∠P = 140°; ∠S = 40°
Step-by-step explanation:
The figure given is a parallelogram.
Consecutive angles (adjacent angles) of a parallelogram are supplementary.
Therefore:
(x + 15)° + (6x - 10)° = 180°
Solve for x
x + 15 + 6x - 10 = 180
Add like terms
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x = 25
✔️m<P = m<R = 6x - 10 (opposite angles of a parallelogram are congruent)
m<P = 6x - 10
Plug in the value of x
m<P = 6(25) - 10 = 140°
✔️m<S = m<Q = x + 15 (opposite angles of a parallelogram are congruent)
m<S = x + 15 = 25 + 15 = 40°
A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the
company repays for the loan and interest is $678,400. How long did it take to pay off the loan?
Answer:
16 years
Step-by-step explanation:
Annual interest payment is 7% * 320k = 22,400
Total interest is 678400-320000=358400
358400/22400=16
The number of years that it takes to pay off the loan will be 16 years.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The formula for interest is written as,
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
A new business borrows $320,000 at a yearly simple interest rate of 7%. The total amount the company repays for the loan and interest is $678,400. Then the equation is given as,
P + I = A
$320,000 + ($320,000 x 7 x T) / 100 = $678,400
$22,400 T = $358,400
T = 16 years
The number of years that it takes to pay off the loan will be 16 years.

Answer this question to get marked as brainliest!!!!
Answer:
we know that sum of angle a and b is 180
so a+b= 180
a= 34 (given)
b= 180-34
b= 146 degrees
Answer:
146 degrees
Step-by-step explanation:
Why?
Angle A and B together = 180 because they make up that one line and a line = 180 degrees and it says that angle A =34 so...
180 - 34 = (B)
146 = (B)

What is the approximate area of a circle with the diameter of 20cm in square centimeters (use 3.14 for pie(
Answer:
314cm
Step-by-step explanation:
the area formular for a circle is a=pi(r)^2. Using this information we can plug in the numbers...
3.14(10)^2. Next square 10 to get 3.14*100. Then you get 314 which is the answer. The reason I used 10 is because the diameter is half of the radius so half of 20 would be 10.
