The mantissa of scientific notation or standard form is between 1 and 10 in absolute value, or 1 ≤ |a| < 10. It can be 1, hence, it does not have to be greater than 1.
Standard form is also called scientific notation and has the form:
a x 10ᵇ
Where b is an integer and is called exponent.
a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.
Usually, a is called mantissa.
Example:
2467 can be written in standard form as:
2467 = 2.467 x 10³
0.0095 can be written in standard form as:
0.0095 = 9.5 x 10⁻³
150 x 10² can be written in standard form as:
150 x 10² =1.5 x 10⁴
-0.062 can be written instandard form as:
-0.062 = -6.2 x 10⁻²

Answer:
Every angle of Square = 90°
diagonal bisects the angle in half.
=> angle FGI = 45°
=> 7x+3=45
=>7x=42
therefore, x=42/7=6
Determine whether these triangles are similar. If so, circle the appropriate reason below. Please show all work.
Answer:
Yes these triangles ate similar.
Step-by-step explanation:
The two triangles are similar if their third angle is equal. The sum of all angles of triangles must be equal to 180 degrees. The triangle 1 has sum of 180 degrees and triangle 2 has sum of 180 degrees. These triangles have third angle same which is 45 degrees.

Given a line segment that contains the points A,B, & C in order, if AB = x + 12, and BC = 2x - 4, and AC = 26, find x.
Answer:
x = 6
Step-by-step explanation:
If A, B and C lies on a straight line in order, then;
AB+BC = AC
x+12+2x-4 = 26
x+2x+12-4 =26
3x+8 = 26
3x = 26-8
3x = 18
x = 18/3
x = 6
Hence the value of x is 6
Convert to 0,125km
to centimetres..........
Answer:
12500 cm
Step-by-step explanation:
0,125 km = 125 m (times 1000 because 1 km = 1000 m)
125 m = 12500 cm (times 100 because 1 m = 100 cm)

Step-by-step explanation:
The diameter is 6, so the square is also 6 feet by 6 feet. This means the square has an area of 36 feet.
Find the area of the circle:
3.14 * 3^2
3 ^ 2 = 9
3.14 * 9 = 28.26
Now find the area of the edges of the square.
36 - 28.26 = ~7.74 ft

Step-by-step explanation:
A right triangle has side lengths d, e, and f as shown below. Use these lengths to find sinx, tanx, and cosx.
Step-by-step explanation:
In the given triangle,
Perpendicular = d
Hypotenuse = e
Base = f
We need to find the values of sinx, tanx and cosx.
We know that,
[tex]\sin \theta=\dfrac{P}{H}\\\\\tan\theta=\dfrac{P}{B}\\\\\cos\theta=\dfrac{B}{H}[/tex],
We have, P = d, H = e and base = f
So,
[tex]\sin \theta=\dfrac{d}{e}\\\\\tan\theta=\dfrac{d}{f}\\\\\cos\theta=\dfrac{f}{e}[/tex]
Hence, this is the required solution.
Using the lengths given, the Trigonometry ratios of the right triangle are:
sin x = d/e cos x = f/etan x = d/fRecall:
In a right triangle where we are given a reference angle, ∅, with three sides, we can solve the triangle using the Trigonometry ratios given as: SOH CAH TOA.Given the following:
∅ = xOpposite = dHypotenuse = eAdjacent = fThus:
sin x = Opp/Hyp = d/e (SOH)
cos x = adj/Hypo = f/e (CAH)
tan x = Opp/Adj = d/f (TOA)
Therefore, using the lengths given, the Trigonometry ratios of the right triangle are:
sin x = d/e cos x = f/etan x = d/fLearn more about Trigonometry ratios on:

If $30,000 then is equivalent to $900,000;
then, what is $1 then equivalent to in today's
dollars?
Answer:
$30
Step-by-step explanation:
You need to figure out how the money changes between then and now. To do that, take now and divide it by then; 900,000/30,000 = 30, the amount now is 30 times that of then. To figure out what any amount then is worth now, multiply it by 30 and you'll get you answer. (In this case: 1*30 = 30)
