Nathaniel invests money in an account paying a simple interest of 6% per year. If he invests $90 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answer:
95.40 total and 5.40 in intreset
Step-by-step explanation:
Answer:
A = $95.40
I = A - P = $5.40
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 90(1 + (0.06 × 1)) = 95.4
A = $95.40
The total amount accrued, principal plus interest, from simple interest on a principal of $90.00 at a rate of 6% per year for 1 years is $95.40.
find each measurement indicated, round your answers to the nearest tenth
Answer:
1. 27.0 m
2. 28.0 degrees
Step-by-step explanation:
1. AB
To find AB, we start by getting the measure of the third angle A
Mathematically;
A + 90 + 51 = 180
The sum of angles in a triangle is 180
A = 180-90-51
A = 39
We then proceed to use the sine rule
Mathematically, the sine rule states that the ratio of the measure of a side and the sine of the angle facing the side is same for each side of the triangle
Thus, with respect to the given triangle;
17/sin 39 = x/sin 90
x = 17sin90/sin 39
x = 27.0 m
Kindly note that we substituted x for AB
2. To find the measure of angle A we use the sine rule as used above, but here we have a missing angle and not a missing side
Thus;
34/sin 127 = 20/sin A
Sin A = (20 sin 127)/34
sin A = 0.469
A = sin^-1 0.469
A = 28.0 degrees

Hackensack and New York City are 12 miles apart. On a map, the two cities are 2 Inches apart. How many miles does 1 Inch represent on the map?
Answer:
6 miles
Step-by-step explanation:
From the question, we are told that 12 miles represents 2 inches on the map.
We are to calculate the amount of miles 1 inch will represent. To do this you will say:
12 miles = 2 inches
x miles = 1 in
Cross multiply;
2 * x = 12 * 1
2x = 12
x = 12/2
x = 6
Hence 1 inch will represents 6 miles on the map

A rectangle has a height of a^2+3 and a width of a^2 +2a+5
Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
Answer:
Area = a^4 + 10 a^2 + 6 a + 15
Step-by-step explanation:
Height: a^2+3
Width: a^2 +2a+5
Area of the entire rectangle = Height x Width
So we have to multiply both expressions and apply distributive property:
Area = (a^2 + 3) x (a^2 + 2a + 5)
Area = a^2 x (a^2 + 2a + 5) + 3 x (a^2 +2a + 5)
Area = a^4 + 2a^2 + 5a^2 + 3a^2 + 6a + 15
grouping terms of same power of a:
Area = a^4 + (2+5+3)a^2 + 6a + 15
Area = a^4 + 10 a^2 + 6 a + 15

Antwan Campbell earns $494 per week. He is married and claims 1 child as a dependent. The state tax rate is 2.25% of taxable income. What amount is withheld from his weekly pay for state income tax?
Answer:
$12.35
Step-by-step explanation:
Amount earned by Campbell per week = $494
Tax rate = 2.25 %
Amount withheld = 2.25% of his earning;
Amount withheld = 2.25 % of 494
Amount withheld = 0.025 * 494
Amount withheld = $12.35
Hence the amount withheld from his weekly pay for state income tax is $12.35

Emilia needs at least $240 to buy new headphones. She has already saved $30. She earns $14 per car that she washes.
What is the least number of cars she can wash to buy the headphones?
a. 14x+30 ≥ 240
B. 14x+30 ≤ 240
C.30x+14 ≥ 240
D. 30x+14 ≤ 240
Explain your reasoning and solve equation:
Answer:
A is the correct equation to use when solving this problem
The least number of cars she can wash is 15
Step-by-step explanation:
If "'x" is the number of cars Emilia washes, then we would need to multiply that by the amount of money she gets from each car which means that "14x" needs to be in the equation somewhere. From this, we can already rule out C and D because those don't have "14x".
Also, since it says that Emilia needs at least $240, that would mean that she needs $240 or higher. Since the sign in equation A shows that, we know that it is equation A.
Since Emilia needs $240 or higher, the least number of cars she could wash would need to give her enough money to get to $240 when added to the $30 Emilia already has. We can multiply 14 by 15 to give us 210 which when added to the $30 she already has, will give us $240 which is the minimum amount of money she needs to buy new headphones.

Cory made 4,500g of candy He saved 1 kg to eat later. He divided the rest of the candy over 7 bowls to serve at his party.
How many grams of candy did Cory serve in each bowl?
Answer:
In each bowl, Cory put 500 grams of candy.
Step-by-step explanation:
You would do 4,500 - 1 (since he save a kilogram for himself), which would equal 3,500.
Then, you would do 3,500 divided by 7 (since there are 7 bowls and he wants to split the remaining candy evenly), which would equal 500.
Answer:
Cory served 500 grams of candy in each bowl.
Step-by-step explanation:
4,500 = 4.50 kilograms
4.50kg - 1.00kg = 3.50kg
3.50kg ÷ 7kg = 0.50kg
0.50kg = 500g
Kathy is a repair technician for a phone company. Each week, she receives a batch of phones that need repairs. The number of phones that she has left to fix at the end of each day can be estimated with the equation P=108−23d P = 108 − 23 d , where P is the number of phones left and d is the number of days she has worked that week. What is the meaning of the value 108 in this equation?
Answer:
What 108 represents here is that the total number of phones she has to fix each week is 108 phones
Step-by-step explanation:
The linear equation is
P = 108-23d
compare this with the general form;
y = mx + c
we have;
P = -23d + 108
We can see that 108 represents the y-intercept in this case
The x-value at the y-intercept is 0
So what this mean is that the number of phones she has to fix each week is 108

Bernadette works at a Car Lot in Buffalo selling used cars. Each month Bernadette receives $2000 plus she receives a 5% commission for all of her sales. In April, Bernadette sold $84,000 worth of used cars. Calculate the total amount of money Bernadette earned in April.
he said SHOW ALL WORK, please help
Answer:
The total amount of money Bernadette earned in April was $6200
Step-by-step explanation:
Let us solve the question
∵ Each month Bernadette receives $2000
∵ She also receives a 5% commission for all of her sales
∴ She earns each month = 2000 + 5% of her sales
∵ In April, Bernadette sold $84,000 worth of used cars
→ Multiply it by 5% to find her commission
∴ Her commission = 5% × 84,000
→ Change 5% to decimal by divide it by 100
∵ 5% = 5 ÷ 100 = 0.05
∴ Her commission = 0.05 × 84,000
∴ Her commission = $4200
→ Add her commission to her fixed amount to find her salary in April
∵ She earned in April = 2000 + 4200
∴ She earned in April = 6200
∴ The total amount of money Bernadette earned in April was $6200
Answer: Bernadette works at a Car Lot in Buffalo selling used cars. Each month Bernadette receives $2000 plus she receives a 5% commission for all of her sales. In April, Bernadette sold $84,000 worth of used cars. Calculate the total amount of money Bernadette earned in April.
Step-by-step explanation:
$2000 + 5% + $84,000= 86000.05 or 86000
All you have to do is just Add - $2000 + 5% + $84,000=
And it gives you 86000.05 or 86000

Explain or show your reasoning.
Answer:
6.8 - 0.9 = 5.9
Step-by-step explanation:
5.9 is the only average that seemed reasonable. Hope I helped.
According to the margin of error, it is found that plausible values for the mean wingspans of the population of local dragonflies are between 5.9 and 7.7 cm.
What is the margin of error of a measure?It is about how much the measure can plausibly differ from the sample mean.
In this problem, considering the sample mean of 6.8 cm and the margin of error of 0.9 cm, the bounds of plausible values are given by:
6.8 cm - 0.9 cm = 5.9 cm.6.8 cm + 0.9 cm = 7.7 cm.More can be learned about margin of error at https://brainly.com/question/25779324

3. there's a pot of gold at the end of the rainbow
1.) As the sun light travels along path through as atmosphere to reach our eyes, the blue light has been mostly remove living mostly red and yellow light remain since red light waves are scattered the list by atmospheric gas molecules
2.) Rainbows are formed when it’s misty or spray the sky with water. It’s not solely just from after a rain; you only need water that can act at as prism and light to shine to create a rainbow.
3.) Having gold at the end of rainbow is just a myth since you can never reach the end of the rainbow. A rainbow is caused by dispersion of light in water droplet which is why they occur when sun comes out after rain.

Answer:
Option A
Step-by-step explanation:
A linear function's standard form is represented by the equation
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept(where the line crosses the y-axis).
So if a function has a slope of 7/2 which is the value of m and crosses the y-axis at 9 which is the value of b then the equation would be
[tex]y=mx+b\\y=\frac{7}{2}x+9[/tex]
