A RECTANGLE HAS SIDES OF "20 - x" AND "x - 5", IF THE RECTANGLES AREA IS 36 SQ. INCHES. FIND THE LARGEST SIDE.
Answer:
12 in.
Step-by-step explanation:
1. area can be calculated as A=s1*s2, where s1 and s2 are the largest and shortest sides.
2. according to the formula before A=(20-x)(x-5). But according to the condition A=36, then (20-x)(x-5)=36;
3. if to solve this quadratic equation, then
-x²+25x-136=0;
[tex]\left[\begin{array}{ccc}x=17\\x=8\end{array}[/tex]
4. if x=3;12, then the sides are 12 and 3 and
5. finally, the largest side s1=12 inches.

the cost of 6 kg of oranges is rs 540 how many kilograms of oranges can be purchased for rs 720
Answer:
This will clear you
Step-by-step explanation:
Given:-
Cost of 6 kg oranges =540
Cost of 1 kg oranges =540/6
=90
Now,
Orange can be purchased =720-540
=180
Again,
Remaining rupees =180/90
=2
Also,
We can buy oranges = 6kg+2kg
=8kg
If the cost of 6 kg of oranges is rs 540, for Rs. 720, you can purchase 8 kilograms of oranges.
To find out how many kilograms of oranges can be purchased for Rs. 720, we need to calculate the cost per kilogram of oranges.
Given that the cost of 6 kg of oranges is Rs. 540, we can find the cost of 1 kg of oranges by dividing Rs. 540 by 6:
Cost of 1 kg of oranges = Rs. 540 / 6 = Rs. 90
Now that we know the cost of 1 kg of oranges is Rs. 90, we can determine how many kilograms of oranges can be purchased for Rs. 720 by dividing Rs. 720 by the cost per kilogram:
Kilograms of oranges that can be purchased = Rs. 720 / Rs. 90 = 8 kg
So, for Rs. 720, you can purchase 8 kilograms of oranges.
In summary, to find the kilograms of oranges that can be purchased for Rs. 720, we divide the given amount by the cost per kilogram, which is obtained by dividing the cost of 6 kg of oranges by 6. The result is 8 kg of oranges that can be bought for Rs. 720.

One week, London earned $313.50 at her job when she worked for 15 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $647.90?
Answer:
31 hours
Step-by-step explanation:
First you take 313.50 divide that by 15 get 20.9 per hour
Then you take 647.90 and divide that by 20.9
So then you're left with 31 as your answer.
A line passes through (0, 2) and has a slope of 1/3.
What is the equation of the line in slope-intercept form?
A) y=1/3x+2
B) y=1/3x−2
C) y=−1/3x+2
Answer:
A)
y=1/3x +2
Step-by-step explanation:
equation of line is y=mx+c
so here the points are (0,2) and the gradient,m is 1/3
the y-intercept, c is 2
as when substituting the result is 2 for the y-intercept
substituting:y=mx+c (0,2)
2=1/3 (0) +c
c= 2
The equation of the line is y=1/3x +2 if a line passes through (0, 2) and has a slope of 1/3 option (A) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The slope-intercept form of the line is:
y=mx+c
The points are (0,2) and the gradient,m is 1/3
c= 2
y = x/2 + 2
Thus, the equation of the line is y=1/3x +2 if a line passes through (0, 2) and has a slope of 1/3 option (A) is correct.

28
Step-by-step explanation:
Answer:
y = 28Step-by-step explanation:
the sum of the internal angles of a triangle is 180 °, from the equal sides it is understood that it is isosceles, therefore it has 2 sides and two equal angles (angle A and angle B) so both A and B are 34 °, x - 5 = 34 °
we find the value of 4y
180 - 34 - 34 = 112
now we find the value of y
4y = 112°
y = 112 : 4
y = 28
Orion buys 3 books for a total of 25.50. He pays $8 plus sales tax for each book. He wants to know how much the sales tax is for one book.
Let "t" equal the sales tax Orion pays for each book. Write an equation that represents this situation.
The equation that represents this situation is 8 + 3t = 25.50.
How to calculate the value?Let the sales tax for each book be represented as t.
Since Orion buys 3 books for a total of 25.50 and he pays $8 plus sales tax for each book. This will be illustrated as:
Cost of book + Tax = Total amount
8 + (3 × t) = 25.50
8 + 3t = 25.50
Collect like terms
3t = 25.50 - 8.
3t = 17.50
Divide
t = 17.50 / 3
t = 5.83
The sales tax is $5.83.
