A plot in the shape of a
rectangle measures 608 m
264m. Equidistant fencing post are
placed along to length and breadth as fsr ss possible. find
The distance between the post
Answer:
The maximum distance between posts is 8 m
Step-by-step explanation:
There is a rectangle-shaped plot where we have to place equidistant posts at the maximum possible distance. The dimensions of the plot are 608 m and 264 m.
The maximum distance between posts is given by the maximum possible divisor of 608 and 264. That number is called the greatest common divisor (GCD).
It can be found by factoring both numbers:
[tex]608 = 2^5*19[/tex]
[tex]264 = 2^3*33[/tex]
The GCD is the product of all common factors with the least exponent. The only common factor is 2 and the least exponent is 3. Thus the GCD is 2*2*2=8.
The maximum distance between posts is 8 m

Solve the equation:
-4x - 12 = 8
-4x - 12 = 8
+ 12 +12
-4x = 20
-4 -4
x = -5
To ensure that x equals -5, let's substitute the negative integer with x.
-4 x -5 - 12 = 8
-20 - 12 = 8
8 = 8
Therefore, the answer is x = -5 because we confirmed our answer by substituting x with -5 and solving the equation and got the both sides of the equation equal.
The solution to the equation -4x - 12 = 8 is x = -5.
To solve the equation -4x - 12 = 8, we'll isolate the variable x by performing the necessary steps.
First, we'll add 12 to both sides of the equation to eliminate the constant term on the left side:
-4x - 12 + 12 = 8 + 12
This simplifies to:
-4x = 20
Next, we'll divide both sides of the equation by -4 to isolate x:
(-4x)/-4 = 20/-4
This yields:
x = -5
Hence, the solution to the equation -4x - 12 = 8 is x = -5.
By performing the necessary operations of addition, subtraction, and division, we have determined that x is equal to -5, satisfying the equation. This can be verified by substituting x = -5 back into the original equation and confirming that both sides are equal.

If you were to use the substitution method to solve the following system, choose the new
equation after the expression equivalent to x from the second equation is substituted into the
first equation.
2x – 3y = -29
x + 4y = 13 (6 points)
1) 2(4y + 13) – 3y = -29
2) 2(-4y + 13) – 3y = -29
3) 2x - 3(4y + 13) = -29
O4) 2x - 36-4y + 13) = -29
Answer:
Option 2
Step-by-step explanation:
We will use the substitution method, as the question asks for. The second equation (where x or y is isolated on one side) will be susbstituted as the x or y in the first equation.
2x-3y=-29
x+4y=13
let's isolate x onto one side in the second equation.
Subtract 4y from both sides
x=-4y+13
now we can substitute the expression as x in the first equation
2(-4y+13)-3y=-29
it's the 2nd option

A gardener who wants a rectangular garden whose lot perimeter is 40 meters is suggested by a fellow gardener a plan that would make it so that the build would have a maximum lot area. What could be the suggestion? You must answer in a mathematical solution. Show work.
Answer:
a*(20-a)
Step-by-step explanation:
Let's assume that the length of the garden is a the width is b and the area is s.
b = 40/2 - a = 20-a
s =a*(20-a)=-a^2+20a=-(a-10)^2+100
then,
when a=10, max(-(a-10)^2) =0, max(s)=100
Ben is making costumes for the school play. For each costume he needs 2.125 yards of fabric. Fabric is $3.49 a yard and sales tax is 6%. Calculate the cost to make 13 costumes
Answer:
$7.87
Step-by-step explanation:
Step one:
given data
For each costume, he needs 2.125 yards of fabric
cost of Fabric is $3.49 a yard
Required
The total cost of making the costume
Step two:
Hence the total cost of fabric needed is = 2.125*3.49= $7.42
sales tax is 6%
= 6/100*7.42
= 0.06*7.42
=$0.45
Therefore total cost of the costume is = 7.42+0.45= $7.87

In a bag,There are red and blue cubes in the ratio 4:7.I add 10 more red cubes to the bag.Now here are red and blue cubes in the ratio 6:7.How many blue cubes are in the bag?
Given:
The ratio of red and blue cubes is 4:7.
After adding 10 more red cubes the ratio of red and blue cubes is 6:7.
To find:
The number of blue cubes.
Solution:
The ratio of red and blue cubes is 4:7.
Let the number of red and blue cubes be 4x and 7x respectively.
After adding 10 more red cubes.
Number of red cubes = 4x+10
Then, the ratio of red and blue cubes is 6:7.
[tex]\dfrac{4x+10}{7x}=\dfrac{6}{7}[/tex]
[tex]7(4x+10)=6(7x)[/tex]
[tex]28x+70=42x[/tex]
[tex]70=42x-28x[/tex]
[tex]70=14x[/tex]
Divide both sides by 14.
[tex]5=x[/tex]
Now,
Number of blue cubes in the bag is
[tex]7(5)=35[/tex]
Therefore, the number of blue cubes is 35.

The length, l, of the shadow cast by an object varies directly as the height, h, of the object. If k is the constant of variation, which equation represents this situation?
A.
l + h = k
B.
lh = k
C.
l = hk
D.
l = h + k
Answer:
C. l = hk
Step-by-step explanation:
the equation for direct variation is y = xk (or y/x = k) so you just replace y and x with l and h
The length of the shadow cast l represents by situation l = hk. Hence, option (C) is correct.
What is the linear relation of an equation?An equation has a linear relation if a variable from that equation varies linearly with the other variable.
for example, x is varied linearly with y then we can write
x ∝ y
x = yk where k will be the constant of variation.
Given that length, l is varies directly as the height h
Hence, l = hk will be the correct representation.

Challenge # 1
Line has a negative slope with positive slope.
Therefore, equation will be,
y = 1.5x - 6
Parallel line to the given line will have same slope = 1.5 but with different y-intercept.
Equation of the parallel line → y = 1.5x + 6
Challenge # 2
Line has a negative y-intercept = -1 (Approx.)
Slope of the line = negative
Therefore, equation of the line will be,
y = -3.7x -1
Line parallel to the given line will have same slope but different y-intercept.
Equation of the parallel line → y = -3.7x + 1
Challenge # 3
Line with negative slope and no y-intercept.
y = -0.8x
Parallel line to the given line will have same slope and different y-intercept.
