50x.2 is the correct expression.
Answer:
The radius of the can, rounded to the nearest hundredth, is 530.66.
Step-by-step explanation:
We want to do the reverse of the formula for V, which is pi(r)^2(h).
to isolate r.
Let's start by writing an equivalent equation to V = h by solving for r
Now, substitute and solve for r
1014 * 3.14 / 6 = 530.66
Ms. Joon, a substitute teacher, breezed into the classroom and settled at the teacher’s desk. She reviewed the plans that had been left for her, making careful notes in the margins. She wrote her name on the whiteboard and greeted students as they entered. When one student grumbled, "Oh no, a sub?”, she cheerfully asserted that everything would be "business as usual.”
What inference can be drawn about Mrs. Joon?
She is hoping to make friends with the students.
She is confident and prepared for her job.
She is well-educated and very intelligent.
She is trying to disguise her nervousness.
The inference is solved and she is confident and prepared for her job
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 represented as A
Now , the value of A is
Substituting the values in the equation , we get
Based on the information provided, the most reasonable inference that can be drawn about Mrs. Joon is that she is confident and prepared for her job. She is described as reviewing plans, taking careful notes, writing her name on the whiteboard, and greeting students cheerfully, which suggests that she is well-prepared and confident in her ability to handle the substitute teaching job.
Her assertion that everything will be "business as usual" despite being a substitute teacher further indicates her confidence and preparedness for the role.
There is no specific information provided to support the other three options of hoping to make friends with students, being well-educated and very intelligent, or trying to disguise nervousness.

Answer:
There are 80 marks in total.
Step-by-step explanation:
Let the number of total marks be .
The percentage score of the student can be written as the ratio
.
However,
.
Equating the two:
.
Cross-multiply (that is: multiple both sides by , the product of the two denominators) to get
.
.
In other words, there are 80 marks in total.
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
therefore your answer is:
