one third of a land is on maize, a fifth of the remainder is on potatoes and the rest which is 0.5 ha is on beans. how much of the land is on potatoes?
Answer: [tex]1250\ m^2[/tex]
Step-by-step explanation:
Let x= Total land.
Then for Maize = [tex]\dfrac{x}{3}[/tex]
For Potatoes = [tex]\dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x[/tex]
For beans = [tex]x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha[/tex]
[tex]\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\ \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\ \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\ x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\ x=0.9375 \ ha[/tex]
1 ha = 10000.00 m²
0.9375 ha = 9375 m²
Land for potatoes = [tex]\dfrac{2}{15}(9375) =1250\ m^2[/tex]
Hence, [tex]1250\ m^2[/tex] of the land is on potatoes.
Find the relation and solve the answers. Options are given below.
Answer:
The correct option is;
A. 453
Step-by-step explanation:
The given numbers are not related by factors, because the factors of 779 are 1, 19, 41, and 779
Similarly the factors of 926 are 1, 2, 463, 926
Therefore, the numbers are related by direct association of each digit of the central number to each of the three numbers on the vertices of the triangle as follows;
For the first triangle, we have the numbers at the vertices are; at the top, 14, at the bottom left is 21, and at the bottom right is 36, we have;
Top number divided by 2 gives 14/2 [tex]{}[/tex] = 7
Bottom left number divided by 3 gives 21/3 [tex]{}[/tex] = 7
Bottom right number divided by 4 gives 36/4 = 9
From which we have the number at the center which is 779
Similarly, for the second triangle, we have the numbers at the vertices are; at the top, 18, at the bottom left is 6, and at the bottom right is 24, we have;
Top number divided by 2 gives 18/2 [tex]{}[/tex] = 9
Bottom left number divided by 3 gives 6/3 [tex]{}[/tex] = 2
Bottom right number divided by 4 gives 24/4 = 6
From which we have the number at the center which is 962
Therefore, when we have, the numbers at the vertices as follows;
At the top, 8, at the bottom left is 15, and at the bottom right is 12, we have;
Top number divided by 2 gives 8/2 [tex]{}[/tex] = 4
Bottom left number divided by 3 gives 15/3 [tex]{}[/tex] = 5
Bottom right number divided by 4 gives 12/4 = 3
From which we have the number at the center is 453.

The cost of cloth is directly proportional to the length. A 3.2-metre length of cloth costs $38
Work out the cost of a 2.4-metre length of cloth.
Answer:
[tex]x = \$28.5[/tex]
Step-by-step explanation:
Given
Variation: Direct Proportion
[tex]3.2m = \$38[/tex]
Required
Determine the cost of 2.4m length
Represent the cost of 2.4m length with x
So, we have:
[tex]3.2m = \$38[/tex]
and
[tex]2.4m = x[/tex]
Cross Multiply:
[tex]3.2m * x = \$38 * 2.4m[/tex]
[tex]3.2 * x = \$38 * 2.4[/tex]
Solve for x
[tex]x = \frac{\$38 * 2.4}{3.2}[/tex]
[tex]x = \frac{\$91.2}{3.2}[/tex]
[tex]x = \$28.5[/tex]
Hence, the cost of 2.4m length is $28.5
how to solve using Substitution or Elimination??? Help!!!
y=3x-1
y=2x+2
Answer:
x=3
y=8
Step-by-step explanation:
the given equations are y=3x-1 --------(1)
and y=2x+2---------(2)
Using substitution method,
and solving y=3x-1
y+1=3x
or y+1/3 =x ------(3)
Putting the value of x= y + 1 / 3 in equation 2
y= 2x+2
or, y = 2 ( y + 1/3) +2
or, y= 2y + 2 / 3 +2
or, y = 2y + 2 + 6 // 3 ( Taking LCM)
Or, 3 y = 2y + 2 + 6 ( the denominator gets multiplied to y)
OR, 3 Y - 2Y =6 PLUS 2
or y = 8
therefore, y=8
now substituting the value of y=8 in equation (3)
y + 1 /3 = x
or ,,, 8 plus 1 by 3 =x
or,,,,, 9 by 3 =x
Therefore, x is 3

The required solution of the quadratic equation (4y - 3)² = 72 is y = 3 ± 6√2/4. Option A is correct.
What is simplification?
Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.
Here,
Given expression, (4y - 3)² = 72
Simplifying the above expression:
(4y - 3)² = 72
4y - 3 = ±√72
4y - 3 = ±6√2
y = 3 ± 6√2/4
Thus, the required solution of the quadratic equation (4y - 3)² = 72 is y = 3 ± 6√2/4. Option A is correct.

Jimmy and Alex each have a CD collection. • The number of CDs in Jimmy's collection can be represented by x. • The number of CDs in Alex's collection is 4 times the number in Walter's collection. • The total number of CDs in both collections is 205. What is x, the number of CDs in Walter's collection?
Answer:
x = 41
And, the number of CDs in Walter's collection is 41
Step-by-step explanation:
The computation is shown below;
Given that
The number of CDs in Jimmy collection = x
The number of CDs in Alex's collection = 4x
And, The total number of CDs in both collections is 205
So, the equation is
x + 4x = 205
5x = 205
x = 41
The alex collection is
= 4 × 41
= 164
So, the walter collection is
= 164 ÷ 4
= 41

What is sin 28°?
I need help ASAP
Answer:
sin 28° = 8/17
Step-by-step explanation:
sin A = opp/hyp
sin 28° = 8/17
The value of sin 28° is: sin 28° = 8/17
So, Option B is correct.
Here, given that, a right angle triangle has hypotenuse = 17 units,
height = 8 units,
base = 15 units.
now, we have, the angle between hypotenuse and base is: sin 28°.
from trigonometry we know that,
sin A = opp/hyp
so, here, we get, sin 28° = height/hypotenuse
putting the values, we have,
sin 28° = 8/17
Hence, The value of sin 28° is: sin 28° = 8/17
So, Option B is correct.

At a six grade graduation celebration there are 80 students and 40 parents.What fraction of the ratio of students to the total number of people at the graduation
Answer:
2/3
Step-by-step explanation:
Given that:
Number of students = 80
Number of parents = 40
fraction of the ratio of students to the total number of people at the graduation
Total number of people at graduation =. (number of students + number of parents)
80 + 40 = 120
Number of students : total people
80 : 120

Let's solve each of these...
Number 1:
[tex]9-3x=0\\9-3(3)=0\\9-9=0\\0=0[/tex]
As you can see 0 does equal itself so this one is true.
Number 2:
[tex]3x+1=9\\3(3)+1=9\\9+1=9\\10\neq9[/tex]
10 does not equal 9 so this one would be false.
Number 3:
[tex]5x-7=1\\5(3)-7=1\\15-7=1\\8\neq1[/tex]
This one is also false.
Number 4:
[tex]2x+4=10\\2(3)+4=10\\6+4=10\\10=10[/tex]
This one is true.
Number 5:
[tex]\frac{x}{3}+5=6\\\frac{(3)}{3}+5=6\\1+5=6\\6=6[/tex]

Triangle GHI with vertices G(4, 1), H(5, -4), and I(2, -8) REFLECTED over the line y = x.
Answer:
[tex]G' = (1,4)[/tex]
[tex]H' = (-4,5)[/tex]
[tex]I = (-8,2)[/tex]
Step-by-step explanation:
Given
[tex]G = (4,1)[/tex]
[tex]H = (5,-4)[/tex]
[tex]I = (2,-8)[/tex]
Reflection: [tex]y = x[/tex]
Required
Determine the coordinates of G'H'I'
The following applies when a line A is reflected over [tex]y = x[/tex]
[tex]A = (x,y)[/tex]
[tex]A' = (y,x)[/tex]
i.e, we simply swap the positions of x and y
So, for:
[tex]G = (4,1)[/tex]
[tex]H = (5,-4)[/tex]
[tex]I = (2,-8)[/tex]
The reflections are:
[tex]G' = (1,4)[/tex]
[tex]H' = (-4,5)[/tex]
[tex]I = (-8,2)[/tex]
