Last year Tyler used 60 feet of fencing to enclose a rectangular garden with an area of 200 ft². This year Tyler plans to use 120 feet of fencing to enclose a garden similar in shape. What will be the area of the garden?
Answer:
Area of new garden = 800 ft²
Step-by-step explanation:
Given:
Old fencing = Parameter of old garden = 60 ft
Area of old garden = 200 ft
Find:
Area of new garden if Parameter of new garden is 120 ft
Computation:
Assume;
Length of old garden = l
Width of old garden = b
So,
2[l + b] = 60
l + b = 30
l = 30 - b
Area of old garden = 200 ft
l x b = 200
So,
(30 - b)b = 200
b² - 30b + 200 = 0
b² - 20b - 10b + 200
b(b-20) - 10(b-20)
(b-20)(b-10)
So,
Width of old garden = 10 ft
Length of old garden = 20 ft
New parameter is double
So,
Width of new garden = 10 x 2 = 20 feet
Length of old garden = 20 x 2 = 40 feet
Area of new garden = l x b
Area of new garden = 20 x 40
Area of new garden = 800 ft²

Four friends are told that the average (mean) of their grades for their favorite class is 84.5%.
Anthony got 86%, Jasmine got 92%, and Kaitlyn got 70%.
Jonathan's grade was not revealed.
What grade did Jonathan get?
PLEASE HELP SOON
Multiply the average by number of people:
84.5 x 4 = 338
This means the total of the 4 grades need to equal 338
To find Jonathan’s grade subtract the other 3 grades from 338:
338 - 86 - 92 -70 = 90
Jonathan’s grade was 90

Noha rides his bike 4 miles and andrew rides his bike 2 miles how long dose it take for them to meet up( there 15 miles away
Step-by-step explanation:
Considering speed of Noha = 4miles per hour
and speed of andrew = 2 miles/hour
The distance between Noha and andrew = 15 miles
Case 1: when they are travelling towards each other( opposite direction)
Then their relative speed becomes = 4+2 = 6miles/hour
Time taken to meet = Distance/relative speed = 15/6 = 2.5 hours
Case2: When they are travelling same direction
Then their relative speed becomes = 4-2 = 2 miles/hour
Time taken to meet = Distance/ relative speed = 15/2 = 7.5 hours

Riley invested $8,500 in an account paying an interest rate of 3.8% compounded daily. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $18,040?
Answer:
Answer:
First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way

Step-by-step explanation:
does anyone know how to do this or could explain how they got their answer?
Answer:
c
Step-by-step explanation:
Answer:
using trigonometric ratio sin, which is
sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse
sin 40°= x/9
multiply both sides of this by 9 to remove the 9 in the side we have x, we will have
sin 40°/9=x
sin° 40 =0.7451
so x= 0.7451/9
which is
x= 0.0827888888
to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Diego predicts that his basketball team has a 23 probability of winning each of their next 7 games. Select two ways Diego could accurately simulate the number of games his team will win.
Answer:
(c) and (e)
Step-by-step explanation:
Given
[tex]Pr = \frac{2}{3}[/tex]
Required
Which 2 options can be used to simulate the given probability.
The two options are (c) and (e)
The proof is as follows;
Option (c)
We have:
[tex]Rolls = 7[/tex]
A cube has 6 faces. So:
[tex]S = \{1,2,3,4,5,6\}[/tex]
[tex]n(S)=6[/tex]
The probability of getting ones, twos, threes, and fours is:
[tex]Pr = \frac{n(1,2,3,4)}{n(S)}[/tex]
In: [tex]S = \{1,2,3,4,5,6\}[/tex]
[tex]n(1,2,3,4) = 4[/tex]
So:
[tex]Pr = \frac{4}{6}[/tex]
Simplify
[tex]Pr = \frac{2}{3}[/tex]
Option (e)
We have:
[tex]White = 10[/tex]
[tex]Red = 5[/tex]
[tex]Count = 7[/tex]
Record the probability of white.
This is calculated as:
[tex]Pr = \frac{White}{Total}[/tex]
[tex]Pr = \frac{White}{White + Red}[/tex]
[tex]Pr = \frac{10}{10+5}[/tex]
[tex]Pr = \frac{10}{15}[/tex]
Simplify
[tex]Pr = \frac{2}{3}[/tex]

10 POINTS!!! NO LINKS!! I WILL REPORT BUT PLEASE SOMEONE HELP ME The table below shows the number of students in four schools with grade
point averages in various ranges. The grade point averages of the students in
which school represent a U-shaped distribution?
Answer:
School C.
Step-by-step explanation:
The answer is school C. A u-shaped distribution would have to have values that when plotted, make a "u". In this case, the first and last values have to be the highest, the second and fourth values have to be in the "middle" and the third value has to be at the bottom. This is the case for school C.
Answer:
B. School C
Step-by-step explanation:
Having a U-shaped distribution means that the school would have the least number in the middle value/values and the most at the ends.
School C exhibits this trend because it has the most on the outermost ranges (82 for between 1.5 and 2, and 78 for between 3.5 and 4.0), as well as the least number for the middle value (26 for 2.5-3.0
The numbers inbetween also follow the trend, as you can see if you read down the column of school C, the numbers decrease as you get to 2.5-3.0 and increase again to 4.0

Each week, Darin's Lawn Service mows 90 lawns in 45 hours at a housing c
The lawns in the complex are the same size.
At this rate, how many hours will it take Darin to mow 12 lawns?
Complete the table.
9514 1404 393
Answer:
6 h
Step-by-step explanation:
The bottom number in the table is half the top number. The missing value is 6 (hours).
__
I like to put the variable in the numerator of a proportion. Here, we can write it as ...
t/12 = 45/90
Multiplying by 12 gives ...
t = 12(45/90) = 12(1/2) = 6
It will take Darin 6 hours to mow 12 lawns.
Answer: 6 is going to be the answer!

What is the absolute maximum or minimum of f(x) = 3x^2-5x-9
Answer:
Absolute minimum / vertex = (5/6,-133/12)
Step-by-step explanation:
Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)

To buy a PS5 bundle, Amir borrowed $850 for 2 years at a simple interest rate of 2.5%. How much did he have to pay back in all? A.$42.50 B.85.00 C.$850 D.$892.50
Answer:
d.
Step-by-step explanation:
Answer:
D. $892.50
Step-by-step explanation:
First we find out the interest:
850 * 2.5% = 21.25
Since this is 2 years we multiply the interest by 2.
21.25 * 2 = 42.50
Now we add the interest with the amount borrowed.
850 + 42.50 = $892.50
So, the answer is $892.50 in total.
Hope this helps! :)
