-- Find the length of the triangle's base.
-- Find the length of the triangle's height.
-- Multiply the base by the height.
-- One half of the product is the area.

6.247 * 10 to the twelfth power in standard form

Scrat [10]

Answer: 6,247,000,000,000

Step-by-step explanation:

Here we have the number:

6.247x10^12 and we want to write this in standard form.

You can see that we have a 10^12, this means that we need to move the decimal dot 12 places to the right, if there is not a decimal to the right, we add a zero.

6.247x10^12 = 62.47x10^11 = 624.7x10^10 = 6,247x10^9 = 62,470x10^8 and so on.

eventually, the standard form is:

6.247x10^12 = 6,247,000,000,000

So we end with 12 digits after the six.

Round 43.7575 to the nearest thousandth. a) 43.700 b) 43.758 c) 43.750 d) 43.757

aleksandr82 [10.1K]

Answer:

B) 43.758

Step-by-step explanation:

Starting from the right side of the decimal point, the places are:

tenths

hundredths

thousands

Each time, you add a zero to the previous number (10 to 100 to 1000, etc), therefore the third decimal would be the thousandths place. If the next figure is a 5 or above, you round up, to the next decimal.

What are the solutions of 3x2 + 14x + 16 = 0? x = , –2 x = –2, x = , 2 x = , 2

miskamm [114]

Assume you mean 3x^2 when you typed the question.

3x^2+14x+16=0
(3x+8)(x+2)=0

x=-8/3 or -2

Area of triangle where A=50, b=31, c=18

Mrac [35]

Use Heron's Formula:
s means semi-perimeter = (50 + 31 + 18) / 2 = 99 / 2 =
49.5
area = sq root [(s * (s-a) * (s-b) * (s-c)]
area = sq root [(49.5 * (s-a) * (s-b) * (s-c)]

This will NOT form a triangle. The longest side (50) is greater than the sum of the other 2 sides.
