True: Two pounds of apples costs more than $3.50.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Andrew Buys 8 pounds of apples for $11.60.
To find the unit rate of apples:
Use division operation,
unit rate = Total cost of apples / total weight of apples
= 11.60 / 8
= $1.45
That means, the unit rate is $1.45 per pound of an apple
So, 2 pound of apples costs 1.45 x 2 = $2.9
Therefore, 2 pound of apples costs less than $3.50.

Write an equation of the line below.
The equation of the line as shown in the image above is: y = 3x.
How to Write the Equation of a Line?Using the slope-intercept form we can write the equation of a line as y = mx + b, where we have:
the slope = m = change in y / change in xthe y-intercept = b = the point where the line cuts the y-axis.To find the equation, use two points on the line, (0, 0) and (-2, -6) to find the slope:
Slope (m) = change in y / change in x = (-6 - 0) / (-2 - 0)
Slope (m) = -6/-2
Slope (m) = 3
The y-intercept (b) = 0
Substitute b = 0 and m = 3 into y = mx + b:
y = 3x + 0

The length of arc FE, considering the dilation is given as follows:
4.42.
What is a dilation?A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure.
For the dilation, due to the multiplication of the side lengths by the scale factor, the side lengths are modified, meaning that the original triangle and the dilated triangle are not congruent.
The angle measures, conversely, remain constant, meaning that the original triangle and the dilated triangle are similar.
As the two circles in this problem are similar, we have that the central angle has the same measure.
The scale factor of the dilation is given as follows:
k = 2.5/5 = 0.5.
Then the length of arc EF is given as follows:
EF = 0.5 x 8.84 = 4.42.

2.85 kilograms of sugar is mixed with 3.15 kilograms of flour. What percent of this mixture is sugar?
Answer:
47.5% of the mixture is sugar.
Step-by-step explanation:
To find the percent of the mixture that is sugar, we need to first find the total weight of the mixture. We can do this by adding the weight of the sugar to the weight of the flour: 2.85 kg + 3.15 kg = 6.00 kg.
Next, we need to divide the weight of the sugar by the total weight of the mixture and multiply the result by 100% to express the answer as a percentage: (2.85 kg / 6.00 kg) * 100% = 47.5%.
Therefore, 47.5% of the mixture is sugar.

3. it is proven that ∠JMK = ∠LMK = ∠JMI = ∠IML = 90° and the diagonals of the rhombus are perpendicular.
Points to remember:
Diagonals of rectangles are equal in length. By the Pythagorean theorem, In a right-angle triangleHypotenuse² = side² + side²
All rhombus are parallelograms with equal sides.Problem - 2
ABCD is a rectangle
Give that DW = 6 cm and BC = 11
As we can see that DW is half of DB
=> Length of DB = 2(6) = 12 cm
Since the diagonals of a rectangle are equal
=> Diagonal DB = Diagonals AC
=> Length of AC = 12 cm
In the given figure, ABD will form right angle triangle
As we know in right angle triangle
Hypotenuse² = side² + side²
=> DB² = AB² + AD²
=> AB² = DB² - AD²
=> AB² = 12² - 11²
=> AB² = 144 -121
=> AB² = 23
=> AB = √23
Therefore,
In rectangle ABCD, DB = 12 cm AC = 12 cm and AB = √23 cm.

Given that IJKL is a rhombus
IK and JL are diagonals of rhombus intersecting at M
To prove that the diagonals are perpendicular we need to prove that
∠JMK = ∠LMK = ∠JMI = ∠IML = 90°
As we know All Rhombus are parallelograms
IJ = JK = KL = IL ---- (1)
In a parallelogram, diagonals bisect each other
Therefore, IM = KM and JM = LM ---- (2)
In ∆IML and ∆JMK
JM = ML [ From 2 ]
JK = KL [ From 1 ]
MK = MK [ Common side ]
∆ IML ≅ ∆ JMK [ By SSS congruency criteria ]
=> ∠JMK = ∠LMK
=> ∠JMK + ∠LMK = 180° [ Linear pair ]
=> ∠JMK + ∠JMK = 180°
=> 2 ∠JMK = 180°
=> ∠JMK = 90°
=> ∠JMK = ∠LMK = 90°
Similarly, ∠JMI = ∠IML = 90°
Hence, it is proven that ∠JMK = ∠LMK = ∠JMI = ∠IML = 90° and the diagonals of the rhombus are perpendicular.

The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Given, A cone, cylinder, and Sphere all have the same radius with the height of the cone and cylinder being twice the radius.
The volume of the cone = [tex]\frac{1}{3}[/tex] πr²h
Since, h = 2r
The volume of the cone = [tex]\frac{1}{3}[/tex] πr² * 2r = 2/3 πr³
The volume of the Cylinder = πr²h
Since, h = 2r
The volume of the Cylinder = πr² * 2r = 2πr³
The volume of the sphere = 4 πr³
Thus, the volume of 3 cones = 2πr³
that is also equal to The volume of one Cylinder.
Thus, the volume of 2 cones = 4/3πr³
that is also equal to The 1/3 volume of the Cylinder.
Thus, the volume of 1 sphere = 4πr³
that is also equal to The volume of 2 cylinders.
Thus, the volume of 1 cone = 2/3πr³

What is the slope of a line perpendicular to the line whose equation is 4 x + 10 y = -140
Answer:
5/2
Step-by-step explanation:
Perpendicular lines are opposite reciprocals:
For example, -2 and 1/2 are opposite reciprocals:
Negate 1/2 to get -1/2. Then take the reciprocal of -1/2 to get -2.
In order to find the slope of an equation, isolate y:
4x + 10y = -140 ==> solve for y
10y = -4x - 140 ==> subtract 4x on both sides
y = (-4x - 140)/10 ==> divide both sides by 10 to isolate y
y = -4x/10 - 140/10 ==> divide each term by 10
y = -2x/5 - 14 ==> simplify
^^ In this equation, the slope is -2/5 since y increases by -2/5 every time x increases by 1.
Now take the opposite reciprocal of -2/5:
First, take the reciprocal of -2/5 by switching the numerator and denominator: -2/5 ==> -5/2
Now negate the result: -5/2 ==> -(-5/2) = 5/2
Hence, 5/2 is the slope of the line perpendicular to 4x + 10y = -140

Write an inequality that can be used to determine the amount of tulle, x, the teacher needs to buy
Answer:
x ≥ 30
Step-by-step explanation:
The teacher wants to make at least 24 tutus. If each tutu requires 1.25 yards of tulle, then she will need to buy at least (1.25 × 24) yards of tulle. 1.25 yards × 24 is 30 yards.

45. A blueprint for a house has a scale of 1:55. A wall in the blueprint is 6 in. What is the length of
the actual wall?
330 ft.
110 ft.
27.5 in.
027.5 ft.
Answer:
the correct answer is 27.5 feet
Step-by-step explanation:
The scale of a blueprint is a ratio that represents the relationship between the size of an object on the blueprint and the size of the actual object. In this case, the scale is 1:55, which means that for every 1 unit of length on the blueprint, the actual object is 55 units long.
If a wall on the blueprint is 6 inches long, then the actual wall is 55 times longer, or 6 inches * 55 = 330 inches. Since there are 12 inches in a foot, the actual wall is 330 inches / 12 inches/foot = 27.5 feet long. Therefore, the correct answer is 27.5 feet
