I’d say D because 10 to the 5th power is 100000 and multiple by 8.2 makes 820000

1. Name the triangle. Tell whether each angle is acute, right, or obtuse -------------------------------------------------------
gregori [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the figure of the 3 triangles is not given.

However, I'll give a general tip on how to identify the types of triangles.

1. Right-angled

When one of the three angles of the triangle is 90 degrees, then that triangle is a right-angled triangle

2. Acute triangle

When all the three angles of the triangle are less than 90 degrees, then that triangle is an acute triangle

3. Obtuse triangle

When one of the three angles of the triangle is greater than 90 degrees, then that triangle is an obtuse triangle.

How to find percentages
Bas_tet [7]

Answer:

Step-by-step explanation:

To calculate percentages, start by writing the number you want to turn into a percentage over the total value so you end up with a fraction. Then, turn the fraction into a decimal by dividing the top number by the bottom number. Finally, multiply the decimal by 100 to find the percentage.

Hope this helps!

Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How
Serggg [28]

9514 1404 393

Answer:

  $8.65×10^3

Step-by-step explanation:

The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.

  West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4

  = (5.38 -1.46 -2.38 -0.675)×10^4

  = 0.865×10^4 = 8.65×10^3

West raised $8.65×10^3.

_____

Your calculator can figure this for you. You can set the final display to scientific notation format, if you need to.
