Answer:
B. 970,000
Step-by-step explanation:
Move the decimal 5 places to the right, since the exponent is a positive 5.
9.7 x 10⁵ = 970,000.
If it is a negative exponent, you would have to move the decimal to the left.

Let a and b be numbers. Use the distributive law to rewrite the expression in a simpler form. a(a+b) =
Answer:
Distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac. From this law it is easy to show that the result of first adding several numbers and then multiplying the sum by some number is the same as first multiplying each separately by the number and then adding the products.
Step-by-step explanation:
a(a+b)
in this question first a will multiply by a+b.
like this;
a(a+b)
= a(a)+ab
= a^2+ab
The simpler form of the expression a(a + b) is [tex]a^2 + ab.[/tex]
Distributive law states that for any numbers a, b, and c :
a(b + c) = ab + ac
Expression: a(a + b) rewrite it using the distributive law to simplify it.
1. Start with the expression a(a + b).
2. Apply the distributive law by multiplying the 'a' outside the parentheses by each term inside the parentheses:
a(a + b) = a * a + a * b
3. Simplify by multiplying:
a(a + b) = [tex]a^2 + ab[/tex]
Therefore, the simpler form of the expression a(a + b) is [tex]a^2 + ab.[/tex]

why is 0.71875 a rational number
Answer:
Because it is terminating.
Step-by-step explanation:
0.71875 is rational because it is terminating (has a clear end). If it were a bunch of random numbers that never ended, then it would be irrational.
0.71875 is a rational number because it is a terminating and non-repeating decimal.
What are rational numbers and irrational numbers?Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers
Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.
Now,the given number is 0.71875
Here we see that digits after decimal 71875 stops,
hence the given number can be convert into fraction of the form a/b
So,
0.71875 = 71875/100000
So 0.71875 can be expressed in the form of a/b
Therefore 0.71875 is rational because it is a terminating and non-repeating decimal.

3T-2 + T -5T= -1
Solve it out please
Answer: T = -1
Step-by-step explanation:
**Disclaimer** I assume that the [T] is a variable. If it was, then you may refer to my answer. If it was not, then you may point it out and I'll redo it.
Given
3T - 2 + T - 5T = -1
Combine like terms
-T - 2 = -1
Add 2 on both sides
-T - 2 + 2 = -1 + 2
-T = 1
Divide -1 on both sides
-T / (-1) = 1 / (-1)
T = -1

find the inverse f(x)=2x/x+3 x≠-3
Answer:

Step-by-step explanation:
f(x) = 2x/(x+3)
f(x)*(x+3)=2x
x(2-f(x))=3f(x)
x=3f(x)/(2-f(x))
f^(-1)(x) = 3x/(2-x)

Answer:
Area = 13.5 cm^2
Step-by-step explanation:
When we know 2 sides and the included angle
the area is =(½)ab sin C
where a and b are the side lengths and C is the angle between them
Area = 1/2 ( 13*7) sin 38
Area = 13.48477

Step-by-step explanation:
The molding needed would be equal to the perimeter of the kitchen floor. The perimeter of the kitchen floor is 2*(9+6)=30 feet
A kitchen floor is 9 feet long and 6 feet wide of rectangle, then the perimeter of the kitchen floor is 30 feet.
How to find the perimeter of a rectangle?For a rectangle with length and width L and W units, we get:
Perimeter of the rectangle = 2(L + W) \: \rm unit
A kitchen floor is 9 feet long and 6 feet wide is given.
The molding needed would be equal to the perimeter of the kitchen floor.
The perimeter of the kitchen floor = 2 (9+6)
The perimeter of the kitchen floor = 30 feet
Therefore, A kitchen floor is 9 feet long and 6 feet wide of rectangle, then the perimeter of the kitchen floor is 30 feet.
