Answer:

x=4

Step-by-step explanation:

20x+5+24x-1=180

44x+4=180

- 4 -4

44x=176

/44 /44

x=4

9514 1404 393

Answer:

  x = 4

Step-by-step explanation:

The two marked angles are supplementary when the lines are parallel.

  (20x +5)° +(24x -1)° = 180°

  44x +4 = 180 . . . . . . simplify

  44x = 176 . . . . . . . . . subtract 4

  x = 4 . . . . . . . divide by 44

__

The two angles are ...

  (20·4 +5)° = 85°

  (24·4 -1)° = 95°

Answer:

Answer:

Percentage decrease = 28%

Step-by-step explanation:

Original distance = 25 miles

New distance = 18 Miles

Change in distance = 25 - 18

= 7 miles

Percentage decrease = change in distance / original distance × 100

= 7/25 × 100

= 0.28 × 100

= 28%

Percentage decrease = 28%

Answer:

The answer is below

Step-by-step explanation:

9) The area of the platform = length * width = 9 m * 12 m = 108 m²

Area = 108 m²

11) 1 km² = 1 km × 1 km = 1000 m × 1000 m = 1000000 m²

But 1 hectare = 10000 m², hence:

1000000 m² = 1000000 m² / 10000 m² per hectare = 100 hectares

1 km² = 100 hectares

12) Area of each paper = 16 cm * 12 cm = 192 cm²

There are 48 sheets, hence:

Total area of sheets = 192 cm² * 48 = 9216 cm²

13) Area of each tile = 12 cm * 10 cm = 120 cm²

The kitchen contains 500 tiles, therefore:

Area of kitchen = 120 cm² * 500 tiles = 60000 cm²

1 m² = 10000 cm²

60000 cm² = 60000 cm² / 10000 cm² per m² = 6 m²

Area of kitchen = 6 m²

Answer:

A=B

Step-by-step explanation:

Equation 1: 70% of A = 0.7a

Equation 2: 35% of B = 0.35a

Equation 3 = (Equation 2) • 2

Equation 3: 70% of B = 0.7a

Equation 3 = Equation 1

A = B

The required solution of the given condition is A = B.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
70% of A = 0.7a

A = 0.7 / 0.7a
A = a  - - - - (1)

Now,
35% of B = 0.35a
B = 0.35 / 0.35a
B = a - - - - - (2)

From equation 1 and 2
A = B

Thus, the required solution of the given condition is A = B.

Answer:

y = 48°

Step-by-step explanation:

In parallelogram STVU,

[tex] m\angle TVU + 60\degree = 180\degree[/tex] (linear pair angles)

[tex] m\angle TVU = 180\degree - 60\degree [/tex]

[tex] m\angle TVU = 120\degree [/tex]

[tex] m\angle UST= m\angle TVU =120\degree [/tex](Opposite angles of a parallelogram)

[tex] m\angle USR= 120\degree(\because S-R-T) [/tex]

[tex] 108\degree + m\angle USR+m\angle PSR= 360\degree[/tex]

Answer:

35 ml/hr

Step-by-step explanation:

Convert lbs to kg

205 ÷ 2.2 = 93.18 = 93.2 kg

Calculate the minute rate

93.2 kg x 5 mcg/kg/min = 466 mcg/min

Calculate hourly rate

466 mcg/min x 60 mins/hr = 27,960 mcg/hr

Drug is expressed in mg, so convert mcg to mg

27,960 mcg = 27.96 mg

Answer: Time taken by pipe C to empty the tank = 5 hours.

Step-by-step explanation:

Pipe A can fill a tank in 5 hours.

Let time taken by Pipe C = x ( hours)

Time taken by Pipe B = x-2 ( hours)

Now, with all 3 pipes open, it takes 3 hours to fill the tank, it can be represented as

[tex]\dfrac15+\dfrac1{x-2}-\dfrac1x=\dfrac 13\\\\\Rightarrow\ \dfrac{x-(x-2)}{x(x-2)}=\dfrac13-\dfrac15\\\\\Rightarrow\ \dfrac{x-x+2}{x^2-2x}=\dfrac{5-3}{15}\\\\\Rightarrow \dfrac{2}{x^2-2x}=\dfrac2{15}\\\\\Rightarrow\ x^2-2x=15\\\\\Rightarrow\ x^2-2x-15=0\\\\\Rightarrrow\ x^2-5x+3x-15=0\\\\\Rightarrow\ x(x-5)+3(x-5)=0\\\\\Rightarrow\ (x-5)(x+3)=0\\\\\Rightarrow\ x=5, -3[/tex]

Time cannot be negative,

So, x=5

Thus, Time taken by pipe C to empty the tank = 5 hours.
