Answer:
the sudha and radha earns 5,670 and 3,360 respectively
Step-by-step explanation:
Since in the question it is mentioned that
Sudha earns 189 in a day
And, radha earns 112 in a day
so in 30 days, sudha earns
= 189 × 30 days
= 5,670
And, radha earns
= 112 × 30 days
= 3,360
Therefore the sudha and radha earns 5,670 and 3,360 respectively

Answer:
Answer is 20+4i
Step-by-step explanation:
I hope it's helpful!
Answer:
20 + 4i
Step-by-step explanation:
[remove brackets]
(4+12i) + (16-8i) --> 4+12i+16-8i
[collect like terms]
4 + 16= 20
12i - 8i= 4i
20 + 4i
When Dalvin runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1 second. Using the empirical rule, what percentage of races will his finishing time be between 64 and 66 seconds?
Answer:
68%.
Step-by-step explanation:
Dalvin's finishing time is normally distributed with a mean of 65 seconds and a standard deviation of 1 second.
Under the empirical rule, 68% of the results will be within 1 standard deviation.
Since the standard deviation is 1 second, 68% of Dalvin's finishing time will be between 64 and 66 seconds.

Can somebody tell me the answer to this please
Answer: D
Step-by-step explanation: We first need to solve the inequality.
First subtract 10 from both sides to get -x < -8.
Now divide both sides by -1, but watch out.
If you multiply or divide both sides of an inequality by
a negative number, you must switch the direction of the inequality sign.
So we have x > 8.
Start with an open dot at 8 and draw and arrow to the right.
We use an option dot since x is greater than but not equal to 8.
So option D is your answer.
Answer:
The correct answer is D

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y
3x - 2y = 0

express 4.67 as a mixed number
Answer:
4.671 = (4.67 × 100)(1 × 100) = 467100.
Step-by-step explanation:
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 467100 is also equal to 467100 when expressed as a mixed number.
Answer:
4 67/100
Step-by-step explanation:
From the info we have, we now that the whole number is 4.
.67 ends in the hundredths place which means it will be a decimal over 100.
Now you have 67/100 and since 67 is prime it can't be simplified.
Put them together and you get 4 67/100

The value of the expression 7⁻² · 7⁵ · 7⁻³ will be 1. Then the correct option is B.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 7⁻² · 7⁵ · 7⁻³
Simplify the expression, then we have
⇒ 7⁻² · 7⁵ · 7⁻³

Answer: C: cubic expression
Step-by-step explanation:
Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
