HELP ME PLS ITS BEEN 20 MINUTES
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
You can combine the two red shaded areas to get a larger portion with an angle of 120°.
The total degrees in a circle is 360° and since [tex]\frac{120}{360} =\frac{1}{3}[/tex],
The area of the combined red shaded area is [tex]\frac{1}{3}[/tex] of the entire area of the circle.
Thus, the probability of choosing the red shaded area is [tex]\frac{1}{3}[/tex]

What does this mean?
Answer:
f(x) = |x| represents the modulus function or absolute value function. It gives us the distance between any point and the origin. Since distance can never be negative so we always consider its positive value only. You can simply multiply the given value with ‘-1’(if the given value is negative).

what is 149,597,870 in scientific notation
Answer:
1.4959787 × 10^8
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 149,597,870 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 149,597,870
New Number: 1.49597870
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 4 9 5 9 7 8 7 0
Decimal Count: 1 2 3 4 5 6 7 8
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.4959787 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.4959787 x 10^8
Step 4
Check your work:
10^8 = 100,000,000 x 1.4959787 = 149,597,870

Here,
a = 3, d = 6 - 3 = 3, n = 10
[tex]\because S_n = \frac{n}{2} \{2a + (n - 1)d \} \\ \\ \therefore \: S_{10} = \frac{10}{2} \{2 \times 3 + (10 - 1) \times 3\} \\ \\\therefore \: S_{10} = 5 \{6 + 7 \times 3\} \\ \\\therefore \: S_{10} = 5 \{6 + 21\} \\ \\\therefore \: S_{10} = 5 \times 27 \\ \\ \huge \orange{ \boxed{\therefore \: S_{10} = 135}} \\ \\[/tex]
Can someone help me out?
Answer:
So the value of s = 7 cm
Step-by-step explanation:
We know that, Area of a triangle = 1/2 * b * h
So, base = 24 cm
height = s
Area = 1/2 * b * h
=>84 = 1/2 * 24 * h
=>84 = 12 * h
=>84 / 12 = h
=> 7 = h (in cm)

what do symbols represent in algebra?
Answer:
One of the most common algebraic symbols is the use of x, y or another letter of the alphabet to indicate a variable or unknown quantity. Common symbols used in algebra also include those related to equality, inequality, factorials and organization, like braces, brackets and parentheses.
Give brainiest please ;-;
Answer:
different variables represent unknown numbers.
Step-by-step explanation:
For example the equation 5x = 15
X is a variable that represents an unknown number. To get the unknown number in the example you need to divide 15 by 5 and 5 by 5 to get X alone and then X will equal 3.
So 5×3=15
