Step-by-step explanation:
For any quadrilateral to be a parallelogram
i) either both the pairs of opposite sides must be equal
ii) Both the pairs of opposite sides must be parallel
iii) Opposite pairs of angles must be equal
iv) Diagonals must bisect each other.
v) A pair of opposite sides must be parallel and equal
Here we are already given that AB || CD
So either we should be given that AD || BC
or we must be given that AB = CD
Here it is given AB = CD as an option.
So Option A) or the first option is the right answer that AB ≅CD is needed to prove ABCD is a parallelogram

In the morning a farm worker packed 4 pints of strawberries every 6 minutes.In the afternoon she packed 1 pint of strawberries every 3 minutes.What was the difference between her morning and afternoon packing rates,in pints per hour?
Answer:
20 pints per hour
Step-by-step explanation:
60/6 = 10
10 x 4 = 40
40 pints/hour in the morning
60/3 = 20
20 x 1 =20
20 pints/hour in the afternoon
40 - 20 = 20
20 pint/hour difference

a truck has a trailer that has a length of 16 ft a width of 7 ft and a height of 11 ft what is the volume
Answer:
1232 is the volume because 16×7×11
Answer:
The volume is 1,232 ft³
Step-by-step explanation:
Volume = lwh = Length × Width × Height =
[given that the length is 16, width is 7, and height is 11]
16 × 7 × 11
4 × 4 × 7 × 11
2 × 2 × 2 × 2 × 7 × 11
2 × 2 × 2 × 2 × 77
2 × 2 × 2 × 154
2 × 2 × 308
2 × 616
1232
________
The volume is the measurable capacity of an object or the metrical space that something holds or takes up.
Just like you multiply the net length and width to find the area of a 2 dimensional object, you can extend that 2d object so that is has height by multiplying by the given height.
What is the area of this figure?
Need it now!!
Answer:
The area is 452cm
Step-by-step explanation:
For the big square we have to multiply 15*18 and that is the area so-
15*18=270
Next we multiply 13 and 14
13*14=182
And now we add 270 and 182 to get the total area
270+182=452

(Choice A)
A
Equilateral triangle
(Choice B)
B
Isosceles triangle
(Choice C)
C
Right triangle
(Choice D)
D
Acute triangle
(Choice E)
E
Scalene triangle
(Choice F)
F
Obtuse triangle
Answer:
That is an obtuse scalene triangle
Step-by-step explanation:
Scalene- has no congruent sides
Obtuse - has an angle that is greater than 90
we can use Pythagorean theorem to confirm this
The Pythagorean theorem states that in an obtuse triangle the hypotenuse squared is greater than the two legs squared added together
so basically [tex]7^2>4^2+5^2\\7^2=49\\4^2=25\\5^2=25\\25+16=41\\49>41[/tex]
therefore it is an obtuse scalene
Answer:
(Choice E) E Scalene triangle and (Choice F) F Obtuse triangle
Step-by-step explanation:
Aside from E, Scalene triangle (as all the sides are of different lengths, we can assume that the angles will also be), the answer can either be B, Isosceles triangle or F, Obtuse triangle, so let's figure that out using the cosine rule! If it is an obtuse triangle, this means Angle ABC is bigger than Angle BAC and Angle BCA. But we can clearly see it is, as it's an Obtuse Triangle is a triangle where 1 angle is bigger than 90 degrees. Let's work out Angles BAC and BCA to find out if the triangle is obtuse or isosceles.
[tex]a^{2} = b^{2} +c^{2} -2bcCosA[/tex] This is the cosine rule formula. Now all we need to do is substitute in the values. We are using the cosine rule because we aren't given any angle values. We use Further Trigonometry instead of SOHCAHTOA as this clearly isn't a right-angled triangle. SOHCAHTOA only applies to triangles with a 90 degree angle, also known as a right-angled triangle. Let's rearrange the cosine formula so that we have everything equal to A instead.
[tex]A = cos^{-1}(\frac{b^{2} + c^{2} - a^{2} }{2bc})[/tex]
We will work out BAC first.
a = 5
b = 4
c = 7
[tex]A = cos^{-1}(\frac{4^{2} + 7^{2} - 5^{2} }{2(4)(7)})[/tex]
A = 44.4 rounded to 3 significant figures
Next, we will work out BCA.
a = 4
b = 5
c = 7
[tex]A = cos^{-1}(\frac{5^{2} + 7^{2} - 4^{2} }{2(5)(7)})[/tex]
A = 34.0 rounded to 3 significant figures
The answer is F, Obtuse triangle and E, Scalene triangle
If we just worked out BAC, we would have noticed that by assuming BCA was also 44.4, the obtuse angle would be 91.2 degrees, which is barely above 90 degrees, therefore we would have correctly guessed the triangle as obtuse from there-on. I just worked out BCA as evidence to support that Triangle ABC cannot be isosceles, therefore we can eliminate that option and classify this triangle as Obtuse.
I hope my explanation helps!!

The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate?
Answer:
The cost of the washing machine is P 3,544
The mark-up rate is 35.21%
Step-by-step explanation:
1. We want to calculate the cost
Mathematically, this is the difference between the selling price and the mark up
We have this as;
4,792 - 1,248 = P 3,544
2. Here, we want to calculate the mark-up rate
Mathematically, this is the percentage of mark-up
That is;
mark-up/cost price * 100%
: 1,248/3,544 * 100% = 35.21%

The inerquartile range of 10 , 11 ,12 ,13 ,
Answer:
hagsjwugabalqiwywowi7w
Answer:
IQR = 2
Step-by-step explanation:
The first step is to find the median of the data set.
The median is the middle value of the data arranged in ascending order. If there is no middle value then it is the average of the values either side of the middle
10, 11, 12, 13
↑ middle
median = [tex]\frac{11+12}{2}[/tex] = [tex]\frac{23}{2}[/tex] = 11.5
The interquartile range ( IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the middle of the data to the right of the median and Q₁ is the middle of the data to the left of the median.
12, 13
↑
Q₃ = [tex]\frac{12+13}{2}[/tex] = [tex]\frac{25}{2}[/tex] = 12.5
10, 11
↑
Q₁ = [tex]\frac{10+11}{2}[/tex] = [tex]\frac{21}{2}[/tex] = 10.5
Then
IQR = Q₃ - Q₁ = 12.5 - 10.5 = 2
