Answer:
Hello, the multiplicative inverse is just another name for reciprocal. You can use this type of method when dividing fractions like:
1/2/3/5
You use the method known as kfc, keep, flip, change like this:
1/2 x 5/3
Notice how 1/2 is kept the same, the division sign is now a multiplying sign, and 3/5 is flipped.
And then you just answer it from there and you get 5/6

I hope this helped you!
Select all expressions that are equivalent to 7x + 4 - (2x - 5).
A: 7x + 4 - 2x -5
B: 7x + 4 - 2x + 5
C: 7x + 4 + (-2x) - (-5)
D: 9x + 9
E: 5x -1
F: 5x + 9
Answer:
B, C, F
Step-by-step explanation:
7x + 4 - (2x - 5) = 7x - 2x + 4 + 5 or 5x + 9
The solution is, B: 7x + 4 - 2x + 5, C: 7x + 4 + (-2x) - (-5), F: 5x + 9, are the expressions that are equivalent to 7x + 4 - (2x - 5).
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the expression is :
7x + 4 - (2x - 5)
now, we have to simplify this to get the equivalent expressions.
so, we have,
7x + 4 - (2x - 5)
= 7x + 4 - 2x + 5
(Removing the brackets)
=7x + 4+ (-2x) - (-5)
= 7x + (-2x) +4 - (-5)
=5x +4 + 5
= 5x + 9
so, the equivalent expressions are, B,C,F.
Hence, The solution is, B: 7x + 4 - 2x + 5, C: 7x + 4 + (-2x) - (-5), F: 5x + 9, are the expressions that are equivalent to 7x + 4 - (2x - 5).

Find the area of each figure. Round to the nearest tenth if necessary
Answer:
c. 143.8 m³
Step-by-step explanation:
The figure can be decomposed into a semicircle and a trapezoid
Area = area of semicircle + area of trapezoid
= ½(πr²) + ½(a + b)h
Where,
r = ½(9) = 4.5 m
a = 9 m
b = 23 m
h = 7 m
Area of the figure = ½(π*4.5²) + ½(9 + 23)7
Area of the figure = 31.81 + 112

A sociologist recorded the number of contacts entered in a cell phone and the number of texts sent in a week for 20 cell phone users. The resulting data were used to conduct a hypothesis test to investigate whether there is a linear relationship between the number of contacts and the number of texts sent. What are the correct hypotheses for the test?
a. H0:β1=0 Ha:β1≠0
b. H0:β1=0 Ha:β1>0
c. H0:β1=0 Ha:β1<0
d. H0:β1≠0 Ha:β1=0
e. H0:b1=0 Ha:b1≠0
The correct option for the hypotheses for the test is a. H0: β1 = 0 Ha: β1 ≠ 0
What is Statistic?The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
The correct hypotheses for testing the linear relationship between two variables can be stated as:
H0: β1 = 0 (there is no linear relationship between the number of contacts and the number of texts sent)
Ha: β1 ≠ 0 (there is a linear relationship between the number of contacts and the number of texts sent)
Therefore, the correct option for the hypotheses for the test is a. H0: β1 = 0 Ha: β1 ≠ 0

Answer:
True
Step-by-step explanation:
Absolute value tells the distance a number is from 0.
[tex]|7|=7[/tex] because 7 is 7 units away from 0.
[tex]|-13|=13[/tex] because -13 is 13 units away from 0.

Absolute value always produces a number greater than or equal to 0, never negative.

Hope it helps. That is the answer
The partial product of 3.4 x 1.2 is (3 + 0.4) x (1 + 0.2).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3.4 x 1.2
3.4 is equal to 3 + 0.4.
1.2 is equal to 1 + 0.2.
Now,
(3 + 0.4) x (1 + 0.2)
= 3 + 0.6 + 0.4 + 0.08
= 3 + 1 + 0.08
= 4 + 0.08
= 4.08
Thus,
3.4 x 1.2 is equal to (3 + 0.4) x (1 + 0.2).

What is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet? Be sure to convert so you are using like units.
Answer:
The height of the tank is 0.5 yards.
Step-by-step explanation:
To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:
1 foot = 0.3333 yards
R = Diameter / 2
R = 120/2 = 60
3.14 x 60 ^ 2 x H = 1,884
3.14 x 3,600 x H = 1,884
3.14 x 1,200 x H = 1,884
3.768 x H = 1.884
H = 1,884 / 3,768
H = 0.5
Therefore, the height of the tank is 0.5 yards.

If f(x)=9ex, find f(5) rounded to the nearest tenth.
Answer:
1335.7
Step-by-step explanation:
f(5)= 9e^x
Substitute x for 5 and solve
The value of the equation f ( x ) = 9eˣ , when x = 5 is 1335.7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be f ( x ) = 9eˣ
The equation is an exponential form , and the value of x is substituted in the equation
When the value of x is 5
The value of e = 2.7182
x = 5
So , substituting the value of x in f ( x ) , we get
f ( x ) = 9eˣ
f ( 5 ) = 9 x e⁵
Now , e⁵ = 148.4131
And ,
The equation f ( 5 ) = 9 x 148.4131
= 1335.718
≈ 1335.7
Hence , the value of the equation f ( x ) = 9eˣ , when x = 5 is 1335.7

Answer:

Step-by-step explanation:
Hello, in (16^5)^1/4, you would multiply the exponents together like this:
16^5 x 1/4= 16^5/4
The exponents multiplied make 5/4. Now you need to multiply 16 with 5/4 like this:
16 x 5/4= 80/4
80 divided by 4 is 32 so therefore, the answer is 32.
