Answer:

total area = 193.31 m²

Step-by-step explanation:

rectangle area = 7 x 15 = 105 m²

semi circle area = (3.14)(7.5²)/2 = 88.31 m²

total area = 105 m² + 88.31 m² = 193.31 m²

8. By area, the former U.S.S.R. was the largest country, having 8.649x106 square miles of land. At this time Canada was the seco
ivanzaharov [21]

Answer:

Canada was 418.912 sq miles smaller than the USSR.

Step-by-step explanation:

Note: I don't know if this question required a calculator so I'll answer without one.

Symbols:

  • USSR area in sq miles = u
  • Canada area in square miles = c

u<em> </em>= 8.649×106

c<em> </em>= 4.797×106

x = how much less area

u<em> </em>= c + x

  • USSR area = Canada area + number of sq miles less

Math:

u = c + x

  • plug in values

8.649×106 = 4.797×106 + x

  • divide by 106 to get rid of the ridiculously large numbers.

8.649 = 4.797 + \frac{x}{106}

  • subtract (use calculator or just traditional subtraction methods)

3.952 = \frac{x}{106}

  • multiply both sides by 106 (use calculator or traditional methods)

418.912 = x

What is the approximate value of 113−−−√ to the nearest tenth?
castortr0y [4]

Answer:

10.6

Step-by-step explanation:

1. First, we need to find which digits √(113) is between, and that would be 10 and 11.

2. Okay, so √(113) is between 10 and 11, meaning 113 is between 100 and 121.

3. Since 113 is a little over half between 100 and 121, let's multiply 10.6 by 10.6 to see how close we are to 113:

  • 10.6 * 10.6
  • 112.36

4. 112.36 is pretty close to 113, therefore, the dot on the number-line should be placed at 10.6.

Describe the error in the work shown.
mihalych1998 [28]

The error was in second step.

3√(y^3)^4 = y^4

(Cube root cancels cube and not power 4)

The answer should be:

xy^4/4

//Hope it helps.
