Answer:
Breadth = 60, Length = 60
Step-by-step explanation
Let length & breadth of rectangular area be : L & B
As, Fencing Yards = 320. So, perimeter ie 2 (L + B) = 320
B = (320 - 2L)/2 → B = 160 - L (*)
Area of rectangle [A] = L x B = L (160 - L) → A = 160L - L^2
Maximising Area, So first derivative d [A] / d [L] = 160 - 2L
d [A] / d [L] ] = 0 → 160 - 2L = 0 → L = 160/2 → L = 80
By (*) : B = 160 - L = 160 - 80 → B = 80
Checking maximising condition, double derivative d^2[A] / d[L]^2 = -2
As d^2[A] / d[L]^2 is negative, L & B values are maximising A

Anagha's mother bought an equal number of ladoos and pedas. She put 13 of the ladoos and 15 of the pedas into a packet and gave it to Anagha to distribute at school. If there were a total of 80 sweets in the packet, how many ladoos did Anagha's mother buy?
Answer:
150
Step-by-step explanation:
Anagha's mother bought an equal number of ladoos and pedas. Let there are x number of ladoos and pedas.
She puts x/3 of the ladoos and x/5 of the pedas into a packet and gave it to Anagha to distribute at school.
Total no of sweets in the packet = 80
[tex]\dfrac{x}{3}+\dfrac{x}{5}=80\\\\\dfrac{5x+3x}{15}=80\\\\\dfrac{8x}{15}=80\\\\x=\dfrac{80\times 15}{8}\\\\x=150[/tex]
So, there are 150 ladoos brought by Anagha's mother.

5x + 10 = 6x – 20
Answer:
30
Step-by-step explanation:
Step 1:
5x + 10 = 6x - 20 Equation
Step 2:
10 = x - 20 Subtract 5x on both sides
Step 3:
10 + 20 = x Add 20 on both sides
Answer:
x = 30

Marcos is baking a cake. He has a recipe for a large cake that calls for 6 cups of flour, 2 cups of sugar, and 1 cup of butter. Marcos only has ½ cup of sugar, so he's going to make a smaller cake. How much flour and butter should he use in his recipe?
Answer:
3/2 cups of flour
1/4 cups of butter
Step-by-step explanation:
Cups of flour = 6
Cups of sugar = 2
Cup of butter = 1
Marcos only has ½ cup of sugar, so he's going to make a smaller cake.
Cups of sugar for big cake = 2
Cups of sugar for small cake = 1/2
Ratio of cups of sugar for big cake to small cake is
= 2 : 1/2
= 2 ÷ 1/2
= 2 × 2/1
= 4
This means to make smaller cake, all recipes should be divided by 4
Flour for small cake = flour for big cake / 4
= 6 / 4
= 3/2 cups of flour
= 1.33
Butter for small cake = Butter for big cake / 4
= 1 / 4 cups of butter
= 0.25

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?
Square root of 5
Square root of 7
5
7
Answer:
7
Step-by-step explanation:
let the other leg be x
Then using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 3² = 4²
x² + 9 = 16 ( subtract 9 from both sides )
x² = 7 ( take the square root of both sides )
x = 7
Answer:
7
Step-by-step explanation:
let the other leg be x
Then using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 3² = 4²
x² + 9 = 16 ( subtract 9 from both sides )
x² = 7 ( take the square root of both sides )
x = 7

Solve for the value of q.
134°
(9q-8)
Answer:
If you mean that 134 degrees = (9q - 8), the answer is: q = 15.78 degrees
Step-by-step explanation:
134 degrees = 9q - 8
142 = 9q
142/9 = q
15.78 = q
q = 15.78 degrees

Determine the slope
(4,12) and (6,20)
Answer:
4
Step-by-step explanation:
Is that the right answer ?
Answer:
Yes, that is correct
Step-by-step explanation:
The formula for the slope can be referred to as "rise over run", a fraction where the rise (change in the y direction) is divided by the run (change in the x direction).
We can get the rise and run by choosing two points on the slope and looking for the change in the x and y direction. In this case, let us use the points (-4,0) and (0,-5). The change in the y direction is from 0 to -5, thus the rise will be -5. Likewise, the change change in the x direction is from -4 to 0 and the run will be 4.
Going back to "rise over run", we divide the rise by the run, giving us -5/4

What is 10/3(fraction) times 6/5(fraction)
Answer:
4
Step-by-step explanation:
When multiplying those fractions, you multiply the top (numerators) by each other and you'll get 60
Then when you divide the denominators you'll get 15.
60 divided by 15 is 4.
10/3 x 6/5 = 4
Step-by-step explanation:
You multiply the numerators together, same with the denominator. You get 60/15. You divide those numbers so you get 4 as your answer. Hope this helps!
