Mark of Ben in semester 1 examination is 586:600. Convert it into percentage
Answer:
97.67
Step-by-step explanation:
600 = 100%
586 = x%
[tex]\frac{100}{x} = \frac{600}{586}[/tex]
x = [tex]\frac{586.100}{600}[/tex] = [tex]\frac{586.100}{6.100}[/tex] = [tex]\frac{586}{6}[/tex] = 97.67

Please help me. I'm struggling with my math
Answer:
a. (4, -3)
b. (-2.5, -4)
Step-by-step explanation:
a. 2x - 4y = 20
x = 4
step 1: plug in x value
2(4) - 4y = 20
8 - 4y = 20
Subtract 8 on both sides
-4y = 12
divide both sides by -4
y = -3
b. y = 6x + 11
2x - 3y = 7
step 1: plug in the y value
2x - 3(6x + 11) = 7
step 2: distribute
2x - 18x - 33 = 7
add 33 from both sides and combine like terms
-16x = 40
divide both sides by -16
x = -2.5
Okay now you plug in the x value to solve for y
y = 6(-2.5) + 11
y =-4
Look at the screen shot and answer the question. Please Explain !!
Answer:
see explanation
Step-by-step explanation:
- 4x + 3 < 23 ( subtract 3 from both sides )
- 4x < 20
x < - 5 ← Her error is on this step
When dividing by a negative quantity the symbol is reversed, that is
Divide both sides by - 4 and reversing the symbol gives
x > - 5

(4/9)^√x=(2/3)^39-√x
Answer:
169
Step-by-step explanation:
(4/9)^√x = (2/3)^39-√x
(2/3)^2√x = (2/3)^39-√x
Comparing the bases ,
2√x = 39-√x
3√x = 39
√x = 13
x = 169

Step-by-step explanation:
what is your questions?????Create a shape with an area of 0.8 m2 and a perimeter close to 400 cm
The dimension of the shape is approximately 1.45 meters by 0.55 meters
Assume the shape is a rectangle, that has the following dimensions.
Length = x
Width = y
So, the area is:
Area = xy
The perimeter is
Perimeter = 2(x + y)
Substitute known values
[tex]\mathbf{xy = 0.8m^2}[/tex]
[tex]\mathbf{2(x+y) = 400cm}[/tex]
Express cm as m
[tex]\mathbf{2(x+y) = 4m}[/tex]
Divide through by 2
[tex]\mathbf{x+y = 2m}[/tex]
Make x the subject (ignore the units)
[tex]\mathbf{x= 2 - y}[/tex]
Substitute 2-y for x in [tex]\mathbf{xy = 0.8m^2}[/tex]
[tex]\mathbf{(2-y)y = 0.8}[/tex]
Open brackets
[tex]\mathbf{2y-y^2 = 0.8}[/tex]
Rewrite as:
[tex]\mathbf{y^2 - 2y + 0.8 = 0}[/tex]
Using a calculator, we have:
[tex]\mathbf{y \approx (0.55,1.45)}[/tex]
Recall that:
[tex]\mathbf{x= 2 - y}[/tex]
So, we have:
[tex]\mathbf{x \approx (2-0.55,2-1.45)}[/tex]
[tex]\mathbf{x \approx (1.45,0.55)}[/tex]
Hence, the dimension of the shape is approximately 1.45 meters by 0.55 meters

Answer:

Step-by-step explanation:
Write a converse theorem that proves lines a and b below are parallel.
If _______ _______ angles are ________, then two lines vk it by a transversal are parallel.
Taking into account the definition of corresponding angles and Corresponding Angles Theorem, if the corresponding angles are congruent, then two lines cut it by a transversal are parallel.
First of all, remember that a transverse line is a line that crosses or passes through two other lines. Sometimes the other two lines are parallel and the transversal passes through both lines at the same angle. However, the other two lines do not have to be parallel for a transversal to cross them.
Corresponding anglesCorresponding angles are angles formed when a transverse line crosses two straight lines. These angles are formed at equivalent corners or at corners corresponding to the transversal when two lines are intersected by a third line.
In other words, if a transversal line intersects two parallel lines, the corresponding angles are those that are on the same side of the parallels and on the same side of the transversal.
Corresponding Angles Theorem
The Corresponding Angles Theorem states that if two parallel lines are cut by a transversal, then the corresponding pairs of angles are congruent.
Remember that if two angles are congruent, then they have the same measure.
The opposite of this theorem is also true: If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.
In summaryIn summary, if the corresponding angles are congruent, then two lines cut it by a transversal are parallel.
