Monica deposited $760 into an ordinary annuity after each quarter for 2 years at 4% interest compounded quarterly. Determine the (a) future value of each account and (b) the total interest amount earned.
Answer:
FV=$823.004
Total interest earned=$63.004
Step-by-step explanation:
FV=PV×(1+i/n)^nt
PV=$760
I=4%
t=2 years
n=4
FV=760+(1+0.04/4)^4*2
=760+(1+0.01)^8
=760+(1.01)^8
=760+(1.0829)
=823.004
FV=$823.004
Total interest amount earned
=FV-PV
=$823.004-760
=$63.004
Find the area of the irregular polygon, pls hurry I need this quickkkkkk
A: 96 in2
B: 120 in2
C: 80 in2
D: 154 in2
Answer:
To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon

Answer:
D
Step-by-step explanation:
a = 20 because the rate of change is –3.
What is a linear function?A linear function has one independent variable and one based variable. The independent variable is x and the based variable is y. a is the steady time period or the y-intercept. it's far the cost of the dependent variable while x = zero.
What are the requirements for functions to be linear?Which will be a linear feature, a graph needs to be both linear (a direct line) and a characteristic (matching each x-value to the most effective y-value). It must also pass a polygraph check, complete an obstacle path, and offer a minimum of 3 references. The qualifications are stringent.

On a multiple-choice test, each question has 4 possible answers. A student does not know the answers to three questions, so the student guesses. What is the probability that the student gets all three questions wrong? The probability that the student gets all three questions wrong is . What is the probability that the student gets all three questions right? The probability that the student gets all three questions right is .
Answer:
P(making 3 wrong guesses) = 27/64
P(making 3 right guesses) = 1/64
Step-by-step explanation:
Number of possible answers per question = 4
Number of right answer per question = 1
Number of wrong answers per question = (4 - 1) = 3
Probability = (Number of required outcomes / Number of Total possible outcomes)
A.) probability of guess 3 questions wrong :
Probability of making a wrong guess = (number of wrong options / total number of options
P(making a wrong guess) = 3/4
Therefore,
P(making 3 wrong guesses) = 3/4 × 3/4 × 3/4 = (27/64)
B.) probability of making 3 right guesses:
P(making a right guess) = (number of right options per question / total number of options per question)
P(making a right guess) = 1/4
P(making 3 right guesses) =(1/4 × 1/4 × 1/4) = 1/64

Miles has a piece of paper that is 1/4 of a large circle.He cuts the paper into five equal parts from the center point of the circle. What is the angel measure of each part?
Answer:
18°
Step-by-step explanation:
First, we find the angle of the large piece of paper that is 1/4 of a circle.
The angle in a circle is 360°. The angle in 1/4 of a circle is:
1/4 * 360 = 90°
He cuts the paper into five equal parts from the center point of the circle. That means the angle was divided into 5 parts:
1/5 * 90 = 18°
Each part has an angle of 18°,
Answer: it's 18
Step-by-step explanation: 18 is the answer hope this helps
Melissa and Jane are planting trees. Melissa plants 10 trees in 1 hour. Jane plants 17 tree in 2 hours.
Enter an equation that can be used to find the number of hours t, takes Melissa and jane to plant 111 trees together
Answer:
6 hours
Step-by-step explanation:
Let both of them plan for t hours to plant 111 trees n t hours
Melissa can plants 10 trees in 1 hour
in t hours she can plant 10 t trees
Jane plants 17 tree in 2 hours
in one hour Jane can plant 17/2 trees
in t hours she can plant (17/2)t trees.
Total trees planted by both of them in t hours in terms of t will be
10t + (17/2)t
= (10t*2 + 17t)/2
= (20t + 17t)/2
= 37t/2
but it is given that they planted 111 trees together
so 37t/2 should be equal to 111
37t/2 = 111
=> 37t = 111*2 = 222
=> t = 222/37 = 6.
Thus, it takes 6 hours for both of them to plant 111 trees together.

solve for p
Answer:
[tex] \boxed{p = 4} [/tex]
Step-by-step explanation:
[tex] = > {p}^{2} = 16 \\ \\ = > {p}^{ \cancel{2}} = {4}^{ \cancel{2}} \\ \\ = > p = 4 \\ \\ \\ OR \\ \\ \\ = > {p}^{2} = 16 \\ \\ = > {p}^{2} = {4}^{2} \\ \\ = > p = \sqrt{ {4}^{2} } \\ \\ = > p = {4}^{ \cancel{2} \times \frac{1}{ \cancel{2}} } \\ \\ = > p = 4 [/tex]
Using the given equation, we know that the square root of p = 16.
Because of this, we also know that the square root of 16 will equal p.
[tex]\sqrt{16} = 4[/tex]
Therefore, p is equal to 4, or p = [tex]\sqrt{16}[/tex].

QUESTION 5 of 10: You are considering selling your home. You consult with an agent who gives you the asking prices of five homes (comps)
in your area: $165,000, $188,000, $175,000, $150,000 and $400,000. The $400,000 is an outlier so you will not include it in your evaluation. In
determining a reasonable asking price, what is the mean of the four remaining comps?
a) $188,000
b) $215,000
Oc) $169,500
d) $175,000
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
Mean = ($165,000 ,+ $188,000 +$175,000 + $150,000) ÷ 4
= $678,000/4
= $169,500

Giardo is using the model below to solve the equation 3×+1 = 4×+(-4) which step could be adjusted so that Gerardo final step results in a positive x value
Answer:
The answer is B. In step one he should have added 3 negative x-tiles to both sides.
See attachment for complete question.
Answer:
The correct option is B.
In step one he should have added 3 negative x-tiles to both sides.
Step-by-step explanation:
Given the equation
3x + 1 = 4x + (-4)
Adding 3 negative x tiles, we have
3x + 1 + (-3x) = 4x + (-4) + (-3x)
1 = x - 4
x = 1 + 4 = 5
