Nyla invested $200 in an account with a 0.75% annual interest rate.
She made no deposits or withdrawals on the account for 3 years. If
interest was compounded annually, what is the balance in her bank
account at the end of 3 years?
A=4.53
B=1,071.88
C=450.00
D= 204.53
Answers
Answer:
D
Step-by-step explanation:
.75% of 200 is 1.5
multiply that by 3
add the original amount
The $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.
It is given that the Nyla invested $200 in an account with a 0.75% annual interest rate.
It is required to find the balance in her bank account at the end of 3 years if compounded annually.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A= P(1+r)^t[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
t = How long the money is deposited or borrowed (in years)
We have P = $200
r = 0.75% = 0.0075
t = 3 years
Putting the values in the formula, we get;
[tex]\rm A= 200(1+0.0075)^3\\\\\rm A = 200(1.0226)\\\\\rm A = \$204.52[/tex]
or A ≈ $204.53
Thus, the $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.

Which of the following best describes the solution of the system of equations below?
Answers
Answer:
D
Step-by-step explanation:
-8x + y = -3..... (equ 1)
9x - y = 3.....(equ2)
y = 8x - 3
-y = -9x + 3(divide both sides by -1*)
hence ..y = 9x - 3
then write y = y in terms of x
which will give you 8x - 3 = 9x - 3
and solve for x which will be N/A

2) 3 : 15 = 1 : 5
3) 22 : 38 = 11 : 19
4) 2 : 5 = 26 : 65
Step-by-step explanation:
2) 5, 3, 1, 15
3 : 15 = 1 : 5
If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.
3) 19, 22, 11, 38
22 : 38 = 11 : 19
If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.
4) 65, 2, 26, 5
2 : 5 = 26 : 65
If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Answers
Answer:
Is the dilation an enlargement or reduction?
Reduction
The point of dilation is about what coordinate?
0,0
What is the scale factor?
1/3
Step-by-step explanation:
The dilation is a reduction. The point of dilation is about coordinate (0,0). The scale factor is 1/3.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).
The image has points (0, 0), (2, 0), (2, -1), and (0, -1).
The required figure has been attached below which represents the dilation.
As we can see that the dilation is a reduction.
The point of dilation is about coordinate (0,0).
This result of dilating a given triangle with a scale factor is 1/3.

You ask 8 students how many letters are in their first name. One person says 6. The other 7 students say a different number of letters. Find the experimental probability of someone having 6 letters in their name based on this experiment.
Answers
Answer:
Step-by-step explanation:
Since only one out of eight said they had six letters
P(6)=1/8
The experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .
What is experimental probability ?Experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
We have,
Total number of students [tex]=8[/tex]
Person having [tex]6[/tex] letters in the name [tex]=1[/tex]
Other [tex]7[/tex] person says different number of letters.
So,
Experimental probability of someone having [tex]6[/tex] letters in their name is determined ;
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
[tex]=\frac{1}{6}[/tex]
So, Experimental probability of someone having [tex]6[/tex] letters in their name is [tex]\frac{1}{6}[/tex] , which is determined using the above given formula.
Hence, we can say that the experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .

C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation: Hope this helps
The correct slope should look like: 1-17/14-18
If you do 1-17 for the numerator then 14-18 must be the denominator (the slope is 4: -16/-4 = 4)
The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent.
