1 answer:
Alla [95]3 years ago
4 0

Answer:

253,000

Step-by-step explanation:

  1. 10^{5} = 100000  
  2. 10^{4} = 10000  
  3. Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
  4. 2.1 × 100,000 = 210,000
  5. Plug 210,000 in: 210,000 + 4.3 × 10,000
  6. 4.3 × 10,000 = 43,000
  7. Plug 43,000 in: 210,000 + 43,000
  8. 210,000 + 43,000 = 253,000

I hope this helps!

Un rombo tiene un ángulo de 22 grados. Cuanto vale la suma de sus ángulos que no midan 22 grados?
Igoryamba

Answer:

The sum of the angles that do not measure 22 degrees is equal to 316°

Step-by-step explanation:

The question in English is

A rhombus has a 22-degree angle. How much is the sum of its angles that do not measure 22 degrees worth?

we know that

The opposite internal angles of a rhombus are equal and the adjacent internal angles are supplementary

so

Let

x -----> the measure of an adjacent angle to 22 degrees in the rhombus

x+22°=180°

x=180°-22°=158°

therefore

The sum of the angles that do not measure 22 degrees is equal to

158°+158°=316°

The length of s is 2/3 the length of t. If s has an area of 368 cm squared find the perimeter of the figure
ser-zykov [4K]
s = \frac{2}{3}t&#10;\\\ \frac{2}{3}t*t = \frac{2}{3}t^2&#10;\\\ \frac{2}{3}t^2 = 368&#10;\\\ t^2 = \frac {3}{2}368&#10;\\\ t^2 = 552&#10;\\\ t \approx 23.5&#10;\\\ s \approx 15.6&#10;\\\ P \approx 78.2

19. The areas of corresponding faces of two similar hexagonal prisms are 25 cm² and 121 cm². What is the ratios of the correspon
Pie

ANSWER

I) 5:11

ii) 5:11

iii) 125:1331

EXPLANATION

Let the side lengths be in the ratio:

x:y

This implies that the area will be in the ratio:

\frac{ {x}^{2} }{ {y}^{2} }  =  \frac{25}{121}

Take positive square root.

\frac{x}{y}  =  \sqrt{ \frac{25}{121} }

\frac{x}{y}  =  \frac{5}{11}

Hence the sides are in the ratio:

x:y=5:11

The perimeter of the smaller hexagon is 6×5=30

The perimeter of the larger hexagon is 6×11=66

The ratio of the perimeter is

30:66=5:11

The volume will be in the ratio

5³:11³

125:1331
