Answer:

x = 13, y = 26

The length of the sides of Δ QRS are QR = 104, QS = 468, RS = 76

Step-by-step explanation:

In ΔRQS

∵ M is the mid-point of side RQ

→ That means M divide RQ into 2 equal parts RM and MQ

∴ RM = MQ

∵ RM = 4x

∵ MQ = 52

→ Equate them

∴ 4x = 52

→ Divide both sides by 4 to get x

∴ x = 13

∵ P is the mid-point of side QS

→ That means P divide QS into 2 equal parts QP and PS

∴ QP = PS

∵ QP = 9y

∵ PS = 234

→ Equate them

∴ 9y = 234

→ Divide both sides by 9 to get y

∴ y = 26

→ Find the length of each side

∵ RQ = 52 + 52

∴ RQ = 104

∵ QS = 234 + 234

∴ QS = 468

∵ RS = 38 + 38

∴ RS = 76

∴ The length of the sides of Δ QRS are QR = 104, QS = 468, RS = 76

Note: PS = 234 is wrong because it made the length of the sides QS = 468, which could not be because the sum of any 2 sides of a triangle must be greater than the 3rd side. So check it.

Step-by-step explanation:

So You would divide 258.75 / 12 = 26.5625

The radius of container is 2.6 inch.

The amount of space occupied by a three dimensional figure as measured in cubic units.

[tex]volume of cylinder= \pi r^{2} h[/tex]

where,

r is the radius

h is the height

According to the given question

shape of the container is cylindrical.

Height of the container, h = 12 inches

Volume of container = 258.75 cubic inches

for the radius of the container

volume of container = [tex]\pi r^{2}h[/tex]

258.75 = 3.14×[tex]r^{2}[/tex]×12

258.75 =37.68×[tex]r^{2}[/tex]

[tex]\frac{258.75}{37.68} =r^{2}[/tex]

[tex]6.9=r^{2}[/tex]

⇒ [tex]r = \sqrt{6.9} =2.62inch[/tex] = 2.6 inch

Hence, the radius of container is 2.6 inch.

Answer:12B - 12M = 36

12B + 15M = 63

Subtract one from the other:

12B + 15M = 63

-(12B - 12M = 36

-------------------------

0 + 27M = 27

27M = 27

M = 1

B - M = 3 (from the original equations)

B - 1 = 3

Answer:

[tex]Range = \{5,1,2,23,-5\}[/tex]

[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]

Step-by-step explanation:

Given

[tex](6,5)\ (-13, 1)\ (-4,2)\ (-5, 23)\ (-10, -5)[/tex]

Required

Determine the domain and range

A relation has the following format:

[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3),(x_4,y_4)........(x_n,y_n)\}[/tex]

The range of the relation are:

[tex]\{y_1,y_2,y_3,y_4........y_n\}[/tex]

While the domain are:

[tex]\{x_1,x_2,x_3,x_4........x_n\}[/tex]

Using this analysis, the domain of the relation is:

[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]

and the Range is

[tex]Range = \{5,1,2,23,-5\}[/tex]

Answer:

each of the eight angles measures 45 degrees

Step-by-step explanation:

The sum of all exterior angles of any polygon always measures 360 degrees.

If it's 'regular' then all angles have the same measures.

If it's an octagon, then it has 8 sides.

360 divided by 8 = 45

Answer:

k = 23% profit on sale price is needed to ensure 30% profit on cost price

Step-by-step explanation:

Let sale price be = s , Profit = k% of s

Let cost price be = 100 , Profit = 30% of c

Cost price (c) + profit (p)  = Sale price (s)

c + 0.3c = s

1.3c = s

Profit as a percentage of sale = (Profit / Sale) x 100

= (0.3c / 1.3c) x 100

= 23%
