We need to find the amount of money Janet invested in 10 years to yield 7425 EUR
She invested EUR 21,214.29
Simple interest = P × R × T
Where,
P = principal = ?
R = interest rate = 3.5% = 0.035
T = Time = 10 years
Simple interest = 7425 EUR
Simple interest = P × R × T
7425 = p × 0.035 × 10
7425 = p × 0.35
7425 = 0.35p
Divide both sides by 0.35
P = 7425 / 0.35
= 21,214.285714285
Approximately,
P = EUR 21,214.29

solve for x please help (show ur work)
Answer:
x = -3
Step-by-step explanation:
12 -4x-5x = 39
Combine like terms
12 - 9x = 39
Subtract 12 from each side
12-9x-12 = 39-12
-9x = 27
Divide by -9
-9x/-9 = 27/-9
x = -3
Answer:
x = -3
Step-by-step explanation:
12 - 4x - 5x = 39
Combine like terms
12 - 9x = 39
Subtract 12 from both sides
12 - 12 - 9x = 39 - 12
-9x = 27
Divide both sides by -9
-9x/-9 = 27/-9
x = -3
Ms. Suzie invested $35,000 in two accounts, one yielding 6% interest and the other yielding 11%. If she received a total of $2900 in interest at the end of the year, how much did she invest in each account?
Answer:
Step-by-step explanation:
6% = 0.06
11% = 0.11
x + y = 35,000 ....................... (1)
0.06x + 0.11y = 2,900 .......... (2)
(1) × 0.06 - (2)
0.06y - 0.11y = 0.06 × 35,000 - 2,900
- 0.05y = - 800
y = 16,000
x = 19,000
Ms. Suzie invested $19,000 in 6% interest account and $16,000 in 11% interest account.

Primo car rental agency charges $21 per day plus $0.20 por milo. Ultimo car rental agency charges $24 per day plus $1.00 per milo. Find the daily mileage for which the Ultimo charge is four times the Primo charge.
The mileage is
Answer:
300 miles
Step-by-step explanation:
Let us consider the miles they travelled is 'm'
Mileage for Primo= 21 + (m × 0.20) = 21+0.2m
Mileage for Ultimo= 24+ ( m× 1.00) = 24 + m
Question says The mileage is equal when Ultimo's charge is 4× Primo
Thus,
4 × (21+0.2m) = 24+ m
84 + 0.8m = 24 + m
60 = 0.2m
m = 300

Assuming you are creating a book with 991 pages with a size of 8.5in x 11in, how many words will the story be?
A student was conducting a study to determine how many pages he would need for the book he is writing. So,
he found that the following number of words fit on each type of the following papers using an 11 point font:
Danas
This question is solved using proportions, as the table gives us the number of words per page given the dimensions, and the number of pages, which lets us calculate the number of words.
Doing this, we get that the story will be composed of 792,800 words.
-------------------------------------------
According to the table, pages of dimensions 8.5in x 11in have 800 words.The book has 991 pages, of 8.5in x 11in dimensions.Thus, considering that there will be 991 pages, each with 800 words, the total number of words in the story will be of:
[tex]991 \times 800 = 792,800[/tex]
The story will be composed of 792,800 words.

Carol wanted to know about how much time students in her school spent surfing the Internet. So she asked 15 of her friends to complete a survey that she had prepared. Will the results of Carol’s survey represent the population of students in her school as a whole, and if so, which sampling method did Carol use?
A. Yes, Carol used simple random sampling.
B. Yes, Carol used systematic random sampling.
C. Yes, Carol used stratified random sampling.
D. No, Carol’s survey was not a random sample.
Answer:
D
Step-by-step explanation:
We can go through each form of sampling and see where this scenario fits.
- Simple random sampling is simply taking a random percentage of the population. In this case, with the population being students in Carol's school, this would entail taking a random sample from her school. As her friends are not randomly selected, this does not fit
- Systematic random sampling means that every nth item is selected. For example, if Carol took every 10th person at her school, this would fit. However, as her friends are not selected by Carol choosing every 5th or 10th person at school (or something like that), this does not fit.
- Stratified random sampling means that different subgroups of the population are selected, and once those are selected, it is randomized to see who out of the subgroup is selected. For example, if Carol took all the men and women in her school and chose 50 random men and 50 random women, this would work. Although Carol's friends may define a subgroup of the population here, she is not asking anyone outside of that subgroup here, so this does not fit.
As none of these fit, the only answer left is D
If or whether Carol's sampling strategy was random and objective will determine if the survey's findings accurately reflect the population of pupils at her school. So, the correct option is D.
What is Random sampling?A statistical method known as random sampling is used to choose a representative sample of people or things from a bigger population. Every member of the population maintains an equal probability of being chosen in a random sample, and there is no systematic bias present in the selection procedure.
Which sample technique Carol employed is unclear given the facts in the question. Carol's poll would not be regarded as a random sample, and the findings might not be representative of the entire student body at her school if she simply asked 15 of her friends to respond.
Therefore, the correct option is D.

Answer:
Its A
Step-by-step explanation:
The tangent of the given circle is FG hence the correct option will be an option (B).
What is a tangent of a circle?The tangent of a circle is a line that intersects the circle at the periphery of the circle.
If you draw a line that goes through the center to the tangent touching point then it will give you a 90-degree angle.
Given the circle it's clear that the tangent is only FG hence it will be the correct option
A circle can have an infinite number of tangents.
In other words, a straight line that only touches a circle twice is said to be tangent to it. The term point of intersection refers to this location
At the tangent line, the tangent to a circle is orthogonal to the radius.

Answer:
$30.00 -( $8.00 + $21.00) =

Step-by-step explanation:

$1.50 $3.00
$4.00 $11.00
SUM $8.00 $20.00
Tax $1.00
The boy have only $1 .
What is percentage?
A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.
According to the given question.
The amount of money the boy initially had = $30.00
The amount of money he spent on tickets = $6
Amount of money spent of drink = $2.50
Amount of money spent on cotton candy =$1.50
Amount of money spent on burger = $4
Amount of money spent on souvenir = $3.00
Amount of money spent on shirt = $11.0
Now,
The total money spent on non-food items
= $6 +$3 + $11
= $20
So, the amount paid as a tax for non food items = 5% of $20 = [tex]\frac{5}{100} (20)[/tex]=$1
And,
The total amount spent including tax
= $1 + $20 + $2.50 + $1.50 + $4.00
= $29
Therefore,
The amount of money is left = $30 - $29 = 1
Hence, the boy have only $1.

The group of values to be plugged into TVM solver is

We have 20 year loan then the number of periods will be
N = 20 x 12
N= 240
and, the Monthly payment is $510 then
PMT = - 510
and, Interest = 19.2%
and, PV = - 205, 000
Thus, N=240 ; I % = 19.2% , P = -205000 , PMT= -$510, Fv =0 , P/Y =12.
