Answer:

It will take [tex]3[/tex] workers to build [tex]95[/tex] birdhouses

Step-by-step explanation:

Given:

[tex]5[/tex] workers to built [tex]120[/tex] birdhouses[tex]=3[/tex] days

To find how long will it take [tex]3[/tex] workers to build [tex]95[/tex] birdhouses

By unitary method,

[tex]1[/tex] worker to built [tex]120[/tex] birdhouses [tex]=3[/tex] × [tex]5[/tex] days

[tex]1[/tex] worker to built

So ,

[tex]1[/tex] worker to built

[tex]3[/tex] workers to built [tex]1[/tex] birdhouse[tex]=\frac{3*5}{120*3}[/tex] ⇒[tex]\frac{1}{24}[/tex]days

[tex]3[/tex] workers to built [tex]95[/tex] birdhouses [tex]=\frac{1}{24}[/tex] × [tex]95[/tex]

[tex]= 3.95[/tex] or [tex]4[/tex] days.

Answer:

A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm

Step-by-step explanation:

This is a geometric sequence.

a%5B1%5D=1.5m=150cm, r=0.74

The formula is

a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29

Just substitute a1 = 150cm and r = 0.74

a%5Bn%5D=150%280.74%29%5E%28n-1%29

That's the rule.

For the second part, substitute n = 6

cm.

Answer:

B

Step-by-step explanation:

The easiest way to find the answer is to convert all of the fractions to have the same denominator,...

A = (22/55 / 11 = 2/5 and 2/5 * 20)            = 40/100

B = (17/20 * 5)                                             = 85/100

C = (4/5 * 20)                                              = 80/100

D = (3/4 * 25)                                              = 75/100

B (Lily) is the highest followed by C (Nikki), D (Sydney), and A (Monica)

Answer:

The choose 2.

[tex]g(f(x)) = \frac{2}{(4x - 3) + 6} \\ \\ = \frac{2}{4x + 3} [/tex]

Answer:

14=3x-2y

[tex]y = m x+ c \\ y = \frac{3}{2} x - 7 \\ y = \frac{3x - 14}{2} \\ 2y = 3x - 14 \\ 14 = 3x - 2y \\ therefore \\ 14 = 3x - 2y \: is \: the \: required \: eqution \: of \: the \: line[/tex]

it can be wrong also

Let's find the value of x,

→ 1.025x = 11.55

→ x = 11.55/1.025

→ x = 11.2682926829

→ [x = 11.27]

So, 11.27 is the solution.

Answer:

There are 5 planets visible without a telescope, Mercury, Venus, Mars, Jupiter, and Saturn (6 if you include Uranus for those with sharp eyes!). All of them plus Neptune move within 7 degrees of the ecliptic.

Venus. After the Moon, Venus is the brightest natural object in the night sky. It is both the Earth's closest neighbor in our Solar System and the planet most similar to Earth in size, gravity, and composition. We can't see the surface of Venus from Earth, because it is covered with thick clouds.

So I think it is A sorry if I am wrong.

Answer:

C. Neptune and Saturn

Explanation:

Neptune and Saturn are both considered 'giant planets'. Therefore, these planets are most likely to be visible from earth.

The fraction of money spent is 5 / 8 x.

The fraction of money left is 3 / 8 x.

This week Harry spent 1/2 of his pocket money on a ticket for a football match. Therefore,

let

x = amount of money he has

Therefore,

amount spent on football match = 1  /2 x

He also spent 1/8 of his pocket money on a scarf at the match.

Therefore,

amount spent on scarf = 1 / 8 x

Fraction of money spent = 1 / 2 x + 1 / 8 x = 4 + 1 / 8 = 5 / 8 x

Fraction of money left = x - 5/8 x = 8x - 5x/8 = 3 / 8 x

Answer:mzxm m mccaca

Step-by-step explanation:s,cscbsmc msc cmca

Step-by-step explanation:

the price is 5 per tile ?

the area of the rectangular room is

12×6 = 72 m²

each m² has 100×100 = 10000 cm²

so, we have for the total area in cm²

72 × 10000 = 720000 cm²

one tile has 10×2 = 20 cm²

so, how many tiles will we need ?

720000 / 20 = 72000 / 2 = 36000 tiles.

so, if truly 1 tile costs 5 Rupees, then we have

36000 × 5 = 180000 Rupees as total costs.

Step-by-step explanation:

1 m = 100 cm

12 m = 1200 cm

6 m = 600 cm

Area of room = l × w

Area = 1200 × 600

Area = 720000 cm²

Area of tile = l × w

Area = 10 × 2

Area = 20 cm²

Total tile = 720000/20 = 72000/2 = 36000

Cost = 36,000 × 5

Cost = $ 180000

8y-40

Step-by-step explanation:

First you expand the brackets

8 x y - 8 x 5

= 8y - 40

Area of a square is side ^2

To find the length of the side using area find the square root of the area.

Side length = sqrt(169)

Side length = 13 feet

Answer:

13 ft

Step-by-step explanation:

The area of a pool is length × width (l × w) , but the length and width are the same so I'll use [tex]b[/tex] representing both length and width:

A = l × w

A = [tex]b^{2}[/tex]

Area of the pool is 169

169 = [tex]b^{2}[/tex]

[tex]b[/tex] = [tex]\sqrt{169}[/tex]

[tex]b[/tex] = 13

Answer:

THE LENGTH OF SIDE=14cm

As,

Hypotenuse ²=Base²+Perpendicular ²

H²=13²+5²

H²=169+25

H²=196

H=14

Answer:

46

Step-by-step explanation:

The sum of the two smaller angle measures is 98.

(2x + 6) + (3x - 8) = 98

Combine like terms.

5x - 2 = 98

5x = 100

x = 20

Plug this into the expressions for the two smaller angle measures.

2x + 6 = 2(20) + 6 = 46

3x - 8 = 3(20) - 8 = 52

The smaller of the two angles measures 46.

In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.

Answer:

m<DEF = 47°

Step-by-step explanation:

Given:

m(DEF) = 266°

Required:

m<DEF

Solution:

m<DCF = ½(m(DEF)) (Inscribed angle theorem)

Substitute

m<DCF = ½(266°)

m<DCF = 133°

Opposite angles in an inscribed quadrilateral are supplementary.

Therefore,

m<DEF = 180° - m<DCF

m<DEF = 180° - 133°

m<DEF = 47°
