Step-by-step explanation:
4.5÷4= 1.125
so each time she goes around the rectangle she's covering 1.125 km and we seed the length is twice the breadth x+2x=1.125
so 1.125 / 3 to give x which is the breadth=0.375 x 2 is equal to 0.75 km or 750 m this is the length of the field
Step-by-step explanation:
The length of a rectangular field is twice it's breadth. A girl jogged around it 4 times and covered a distance of 4.5 km. What is the length of the field?
The distance cover in 4 laps is 4.5 km, So one lap is 4.5/4 = 1.125 km.
Let the breadth of the field be B so the length will be L or 2B.
The perimeter of the field is 2L+2B or 4B+2B = 6B = 1.125, so B = 1.125/6 = 0.1875 km and the length is 2*0.1875 = 0.375 km.
Check: perimeter = 2*0.375 + 2*0.1875 = 1.125 km and 4 laps covers 4*1.125 = 4.5 km. correct.
The field is 375 m long.

what is the area of the rectangle whose length is (x + 5) and width (x-5)
Answer:
area of the rectangle is length *breadth
length =(x+5)
breadth =(x-5)
=(x+5)(x-5)=x^2-5x+5x-25=x^2-25
Answer:
[tex]\boxed {\boxed {\sf a=x^2-25}}[/tex]
Step-by-step explanation:
The area of a rectangle is the product of length and width.
[tex]a=l*w[/tex]
The length is (x+5) and the width is (x-5).
[tex]a= (x+5)(x-5)[/tex]
We have two binominals, so we can multiply using FOIL: First, Outside, Inside, Last.
F: x*x= x²O: x*-5= -5x I: x*5= 5x L: 5*-5 = -25[tex]a= x^2-5x+5x-25[/tex]
Combine the like terms: -5x and 5x. They cancel each other out.
[tex]a=x^2-25[/tex]
The area of the rectangle is x²-25

The temperature at 12 am was 44 degrees. The temperature dropped steadily for the next 8 hours to reach the daytime low of 20 degrees. Create an equation for the relationship between temperature and the time.
Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)
The equation for the relationship between temperature and time is
T = 44 - 3x
Where x is the number of hours and T is the temperature.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at 12 am = 44°
The temperature after 8 hours = 20°
Now,
The temperature drops steadily.
This means,
Temperature drops in an hour.
= (44 - 20) / 8
= 24/8
= 3°
The equation for the temperature after x hours.
= 44 - 3x
Thus,
The steady temperature drop in an hour is 3°.

Jaylen will deposit $1,750 in an account that earns 6% simple interest every year. His best friend, Eli, will deposit $1,600 in an account that earns 8.5% interest compounded annually. The deposit will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Compare and contrast the two friends’ account after 5 years
Answer:
Jaylen- 2275

Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2
Answer:
(gof)(-8) = 210
Step-by-step explanation:
(gof) = (-x + 8)² - 3(-x + 8) = 2
= x² - 16x + 64 + 3x - 24 + 2
= x² - 13x + 42
(gof)(-8) = (-8)² - 13(-8) + 42
= 64 + 104 + 42
