Answer:

Step-by-step explanation:
First, make a common denominator for both, which is 20. So, 3/4 = 15/20. Then 4/5= 16/20. 15/20 < 16/20, so 3/4 < 4/5.

14. Mrs. Buchanan is planning marching routines for the school band. The band has 36 members. Band members can march in any number of rows as long as each row has the same number of members. The marching path, however, limits members to 6 per row.
Answers
Question:
Make a list of the different arrangements that Mrs. Buchanan could use.
Answer:
[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]
Step-by-step explanation:
Given
[tex]Members = 36[/tex]
[tex]Rows\ Limit = 6[/tex]
Represent the rows with x and the column, y.
This means that:
[tex]x * y = 36[/tex]
Make y the subject:
[tex]y = \frac{36}{x}[/tex]
The list is then generated as follows:
When x = 6.
[tex]y = \frac{36}{6} = 6[/tex]
[tex](x,y) = (6,6)[/tex]
When x = 5
[tex]y = \frac{36}{5} = 7.2[/tex]
This result can not be use because the result of the number of columns must be an integer
When x = 4
[tex]y = \frac{36}{4} = 9[/tex]
[tex](x,y) = (4,9)[/tex]
When x = 3
[tex]y = \frac{36}{3} = 12[/tex]
[tex](x,y) = (3,12)[/tex]
When x = 2
[tex]y = \frac{36}{2} = 18[/tex]
[tex](x,y) = (2,18)[/tex]
When x = 1
[tex]y = \frac{36}{1} = 36[/tex]
[tex](x,y) =(1,36)[/tex]
So, the possible list is:
[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

For each of the 6 pairs of triangles below, determine if the triangles can be proved congruent. If yes, tell which of the patterns it fits (SSS, SAS, ASA, or AAS)
Answers
Answer:
a. is congruent by SSS
b. is congruent by AAS
c. is congruent by ASA
d. is congruent by SAS
Step-by-step explanation:
a. is SSS because all sides are marked
b. is AAS because the point where the two triangles meet are vertical angles and the one side of the triangle is marked congruent making AAS
c. is ASA because the angles are on segment FG and segment BC and there is a congruent line in between the two angles making ASA
d. is SAS because the triangles share the segment QS and when two triangles share a segment, that segment is congruent. the outside segment is congruent and then there is an angle and then the inside segment is congruent

6. The base of a triangular field is three times its height. If the cost of cultivating the field
at 36 per hectare is? 486, find its base and height (1 hectare = 10000 m²).
Answers
Answer:
base = 519.62, height = 173.21 m
Step-by-step explanation:
Let the base and height of the triangle be represented by b and h respectively.
Thus,
b = 3h
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
For the given triangle,
area = [tex]\frac{1}{2}[/tex] x b x 3h
= [tex]\frac{3}{2}[/tex]bh
Area of the triangle = [tex]\frac{3}{2}[/tex]bh
To determine the number of hectares,
36 per hectare = 486
hectare = [tex]\frac{486}{36}[/tex]
= 13.5
numbers of hectares = 13.5
Area of the hectares = number of hectares x 10 000 m²
= 13.5 x 10 000
= 135000
Total area of the hectares = 135 000 m²
So that,
area of the hectares = area of the triangle
area of the triangle = [tex]\frac{3}{2}[/tex]bh
135 000 = [tex]\frac{3}{2}[/tex]bh
270000 = 3bh
bh = [tex]\frac{270000}{3}[/tex]
= 90000
bh = 90000
But, b = 3h
3h x h = 90000
3[tex]h^{2}[/tex] = 90000
[tex]h^{2}[/tex] = [tex]\frac{90000}{3}[/tex]
= 30000
h = [tex]\sqrt{30000}[/tex]
= 173.2051
h = 173.21 m
So that,
b = 3 x 173.2051
= 519.6153
b = 519.62
Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.

Answers
Answer:
The answer is below
Step-by-step explanation:
a) Let y represent the amount of time kiran slept, hence:
y = x - (1/10)x = x - 0.1x
y = 0.9x
b) Let y represent the amount of time Mia practice, hence:
y = x - (2/5)x = x - 0.4x
y = 0.6x
c) Let y represent the amount of drink kiran drank, hence:
y = x + (4/3)x = 7x / 3
y = 7x/3
d) Let y represent the money Mai spent, hence:
y = x - (1/4)x = x - 0.25x
y = 0.75x
e) Let y represent the amount of almond kiran ate, hence:
y = x + 1.5x = 2.5x
f) Let y represent the recycling Mai collected, hence:
y = x - (3/10)x = x - 0.3x
y = 0.7x
g) Let y represent the amount of km kiran walked, hence:
y = x + (3/8)x
y = (11/8)x
h) Let y represent the amount of puzzles mai completed, hence:
y = x + (3/5)x = x + 0.6x
y = 1.6x

out of these numbers which of them differ by 46. 29,17,38,71,35,63,24
Answers
Answer:
71
Step-by-step explanation:
Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd
71
We do not need to look at all differences.
We need to find two numbers fairly far appart,
and not all look promising.
You could look at approximate differences,
or you could look at the last digit.
71-35 and 63-17 are the only promising differences,
because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,
and when you calculate the last digit you calculate
11-5=6 and 13-7=6.
71-35=36
