A) The ingredient she needed = Fruit juice = 21 litres
Lemonade = 14 litres
B) The extra punch she can make = 20litres
C) The ratio of fruit juice and lemonade for second batch = 7:6
What is Ratio?
A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. Similarly, the ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.
A)
Let 3x be fruit juice and 2x be the lemonade
3x + 2x = 35litres
5x = 35
x = 35/5
x = 7
Then, required ingredient she needed
Fruit juice = 3x7 = 21 litres
Lemonade = 2x7 = 14 litres
B)
According to question
The amount of fruit juice she had = 12litre
Let x be 12litre
as we know that the ratio of fruit juice to the lemonade is 3 : 2
Thus,
Fruit juice = 3(x) = 12 litres
x = 12/3
x = 4
Fruit juice = 3 x 4 = 12litres
putting the value in lemonade
Lemonade = 2(4) = 8 litres
So, The extra punch she can make :
12 + 8 = 20litres
C)
The ratio for new second batch she added 4litres in lemonade
Then it become :
Fruit juice = 21 litres
Lemonade = 14 litres + 4litres = 18
The ratio will be
21:18
7:6
Thus, the ratio of fruit juice to lemonade in second batch will be 7:6

Step-by-step explanation:
h = # of hours worked
{10h and {15(h-40)+400 are both functions i.e. simplified equations
simply fit the # of hours worked in each equation to get the values. you can also double check your work or to understand better
to do so, take (h) # of hours worked and multiply by the pay rate. This gives the total pay over the work week. then take the extra hours beyond the 40. ie 7. if $10 is the pay rate per hour and OT is 1.5xnormal pay then 10x1.5=15. Multiply 15x7 and you get 105 then add to 400 and you get $505. 400 comes from 10(40).
part b and c is just setting the functions.
so instead of 40 hrs per week your full-time rate is now 38 and anything beyond would be counted as overtime. so a normal work week of 38 hrs x the $10/hr would equate to $380 for the week.
part c, if the hours per week were kept normal at 40hrs/week but the pay rate is increased this then changes 10 = h to 12 = h. if 12=h and you work 40hrs/week, then 12(40)=$480 for the normal work week. also this changes your OT pay from 10(1.5)=15 to 12(1.5)=$18

How to find the equation of a line?The equation of a line can be represented in different form such as point slope form, slope intercept form and standard form.
Therefore, the equation of the line is parallel to k.
Parallel line shave the same slope.
Therefore, let's find the slope of k to find the slope of the equation of the line.
Hence, using (7, 2)(1, -1)
m = -1 - 2 / 1 - 7
m = - 3 / -6
m = 1/ 2
Therefore, the slope of the line is 1 / 2. Let's find the y-intercept using the point (-1, 3)
3 = 1 / 2(-1) + b
3 = - 1 / 2 + b
b = 3 + 1 / 2
b = 7 / 2
Hence, the equation is as follows;

For a particular rectangle, twice the width is 4 meters shorter than the length. The area of the rectangle is 126 square meters. What is the perimeter of the rectangle? ? meters
Answers
Let l be the length of the rectangle and w its width.
Then its area is given by:
a = l*w
Its perimeter is given by:
p = 2l + 2w
We also know that, for this specific triangle, we have:
2w = l - 4
l = 2w + 4
a = 126 m²
Applying this result in the area formula, we have:
w*l = 126
w(2w + 4) = 126
2w² +4w = 126
2w + 4w - 126 = 0
Therefore, w = 7 m and l = 2*7 + 4 = 10 m

Answers
After simplification of 4√(384.5)³ using logarithm, the resulting answer is 30158.13684.
What is a logarithm?The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number. When measuring the relative change of a value rather than its absolute difference, logarithmic scales are helpful. Moreover, logarithmic scales are used to compress large-scale scientific data because the logarithmic function log(x) grows very slowly for large x. Common logarithms, with a base of 10, binary logarithms, with a base of 2, and natural logarithms, with a base of e 2.71828, are the four most popular types of logarithms.So, 4√(384.5)³ using logarithm:

What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter. There stood several practical applications for calculating the perimeter. Perimeter is the length of the shape's boundary. It is given by the sum of the shape's sides. It has one dimension and is measured in linear units. Area, on the other hand, quantifies the amount of space occupied by the shape. It has two dimensions and is measured in square units. The perimeter of an object is the distance around it.Therefore,
The sides of the rectangle are in the ratio of 7: 5
Let the length 1=5x

(d) The fence posts cost $17 and the diagonal pieces cost $3.50. Calculate Kara’s total cost.
Answers
The materials and cost of Kara's project obtained using Pythagorean theorem, are;
(a) Distance between fence posts is 2•√(14) feet
(b) Kara needs about 12 fence posts
(c) Kara will need 22 diagonal pieces
(d) Kara's total cost is $281
What is the Pythagorean theorem?Pythagoras theorem can be stated as, the square of the length of the hypotenuse side of a right triangle is equal to the sum of the squares of the other two sides.
The drawing obtained from a similar question consists of two diagonals between consecutive posts.
(a) The given parameters are;
Height of the fence post = 5 feet
Length of the diagonal pieces = 9 feet
The distance, d, between the fence posts using Pythagorean theorem gives;
d² = 9² - 5² = 56
d = 2•√(14)
The distances between the fence posts should therefore be 2•√(14) feet
(b) The number of fence posts, n, is given by the equation;
2•√(14) × n = 93
Which gives;
[tex] \displaystyle {n = \frac{93 }{2 \cdot \sqrt{14}} \approx 12.43}[/tex]
Given that after the 12th post, the 1st post comes next and the distance remaining is less than d, the number of posts, n is 12
(c) The number of diagonal pieces, m, needed, given that there are two diagonal pieces between two posts and there is only 11 in between spaces, gives;
m = 2 × 11 = 22
There are 22 diagonal pieces
(d) Cost of a fence post = $17
Cost of a diagonal piece = $3.5
Total cost, C, is therefore;
C = 12 × 17 + 22 × 3.5 = 281
Kara's total cost is $281

A circle passes through the points (3, 2) and (7, 2) and has radius 2√2. Find the two possible equations for this circle.
Answers
Answer:
(x-5)²+y² = 8(x-5)²+(y-4)² = 8Step-by-step explanation:
radius, r = 2√2
let the center be A(a, b):
The distance from the center to any of the 2 points is r.
So for (7, 2):
it satisfies the equation:
(x-a)²+(y-b)² = r²
Substituting x and y:
(7-a)²+(2-b)² = (2√2)²
squaring both sides:
(7-a)² + (2-b)² = 8
a² +b² - 14a -4b + 49+ 4= 8
a² +b² - 14a -4b + 45= 0 (Eqn 1)
For (3, 2):
it also satisfies the equation:
(x-a)²+(y-b)² = r²
Substituting x and y:
(3-a)²+(2-b)² = (2√2)²
squaring both sides:
(3-a)² + (2-b)² = 8
a² +b² - 6a -4b + 9+ 4= 8
a² +b² - 6a -4b + 5= 0 (Eqn 2)
We can now proceed by elimination:
(Eqn 2) - (Eqn 1):
(a² +b² - 6a -4b + 5) - (a² +b² - 14a -4b + 45) = 0
- 6a - -14a+ 5 - 45 = 0
8a - 40 = 0
8a = 40
a = 40/8
a = 5Putting a back into (Eqn 2):
a² +b² - 6a -4b + 5= 0
5² +b² - 6(5) -4b + 5= 0
25 +b² - 30 -4b + 5= 0
b² -4b = 0
b(b -4) = 0
Values of b:
b = 0 and b = 4POSSIBLE EQUATIONS OF CIRCLE:
Since we have 2 values of b, we have 2 possible centers:
(5, 0) and (5, 4)
Putting the centers into the standard equation of the circle above, we obtain:

A bearing is a measurement of direction that uses North as a point of reference. Your bearing is 00° if you are moving north.
The angle from north to this bearing, measured counterclockwise, is the actual bearing. Utilize the knowledge that west is 270° from the north, south is 180°, and east is 90°.
The number of degrees in the angle measured counterclockwise from the north line to the line connecting the center of the compass is the bearing of a point.
How do you determine bearing angle?
The bearing is the angle subtracted in a clockwise direction from north to west. The bearing is 270° - 17° = 253° since the angle from north to west is 270°.
