Answers

Answer:

1.37 × 10⁴ feet

Step-by-step explanation:

Standard form is a way or method used in mathematics to write very large or very small numbers in a compact form by raising them to the power of 10 (exponents)

She read that the Grand Teton in Wyoming is about 1.37 × 10⁴ feet high.

The standard form of writing this height = 1.37 × 10⁴ feet.

The square of 356 is 126,736 and the square of 357 is 127,449. What is 3582? Try to solve this problem without multiplying. Show your work.

Answers

Answer:

The problem to get 358² is solved by adding 357 twice and then add 1 to the value of 357²

Step-by-step explanation:

The given information are;

The square of 356 = 126,736

The square of 357 = 127,449

We note that 357² = (356 + 1)² = 356² + 2×356 + 1 = 126,763 + 712 + 1 = 127,449

We can write the above equation as follows;

357² = (356 + 1)² = 356² + 356 + 356 + 1 = 126,763 + 712 + 1 = 127,449

357² = 127,449

Similarly, we have;

358² = (357 + 1)² = 357² + 357 + 357 + 1 = 128,164

358² =  128,164

We can also look at the question as forming squares with tiles

To form the square tile with 358 units per side, we add an extra row and column of 357 tiles each. Completing the figure with an extra tile at the top right or left corner

Therefore, the area of the 358 unit per side square = The area of the 357 unit per side + 357 + 357 + 1 =  128,164

A triangle has sides with lengths of 42 millimeters, 43 millimeters, and 58 millimeters. Is it a
right triangle?

Answers

Answer:

No

Step-by-step explanation:

42 x 42 = 1764

43 x 43 = 1849

1764 + 1849 = 3613

and the sqaure roof of 3613 is 60.11

60.11 does not equal 58

so no it is not a right triangle

4. Two times a number added to another number is 25. Three times the first number minus the other number is 20. Find the two numbers.

Answers

Answer:9 & 7

Step-by-step explanation:

Let x be the first number and y be the second.

 

2x + y = 25

3x - y =20

 

1) Add them together.

 

5x = 45

x = 9

 

2) Solve for y.

 

2(9) + y = 25

y=7

 

3) Check your work on the other equation.

 

3(9) - (7) = 20

27 - 7 =20

20 = 20

Last week, a GameStop store sold some $43 games and some $30 games for a total of
$485. What was the total number of games sold?
Explain your reasoning.

Answers

Answer: The total number of games sold by the GameStop is 14. That is 5 games of $43 and 9 games of $30.

Step-by-step explanation:

Considering some games of $43 were sold and others for $30 were also sold in arriving at the total of $485 sold.

If 5 games of $43 were sold it gives $215.

To get the difference, you subtract the amount sold for $43 from the total.

$485 - $215 = $270

To arrive at how many $30 games were sold;

$270 ÷ $30 per game = 9 games

Therefore, 5 games of $43 combined with 9 games of $30 gives a total of 14 games.
