What does it mean when a question number is circled in a textbook

1 answer:

5 0

This is only my opinion. I could be wrong.

My guess is:

Somebody else used that book before you, maybe last year or
the year before, and it was somebody who didn't mind writing
in his book.

One day he didn't have time to write down the homework in his
assignment notebook, so he just circled the homework problems
in his textbook.

Shay is putting a square canvas painting in for her new room, and the area of the canvas painting is 196 cm².

Alika [10]

Answer:

The total distance around the canvas painting is 60 cm.

Step-by-step explanation:

The total distance around the canvas painting is 60 cm, we know this because, to find the perimeter of a square you add the length of all 4 sides together. To find the length of 1 side we take the square root of the area which is 196 cm², this equals 14 cm. To find the perimeter we add all 4 sides together, so 14+14+14+14=60 cm.

How do You graph : y-10= -5x?

miv72 [106K]

Equation:

y - 10 = -5x

Solve:

(y - 10) + 10 = (-5x) + 10

y = -5x + 10

Remember the formula (Slope Intercept Form):

y = mx + b

m = Slope (Rise/Run)

b = Y-intercept

So your graph would look something like the attached image:

If x = -3 and y = 4x - 1, then y equals what number

Masteriza [31]

$\huge\text{Hey there!}$

$\large\textsf{y = 4x - 1}$

$\large\text{If x= -3, then substitute it into the given equation}$

$\large\textsf{y = 4(-3) - 1}$

$\large\textsf{4(-3) = \boxed{\bf -12}}$

$\large\textsf{y = -12 - 1}$

$\large\textsf{-12 - 1 = y}$

$\large\textsf{-12 - 1 = \boxed{\bf -13}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf y = -13}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

Suppose a pizza must fit into a box with a base that is 12 inches wide.

mojhsa [17]

The area of the whole pizza must be at most 113.10 square inches in order to perfectly fit in the box. The values of r represent the half of the length of the pizza with respect to its center. In this case, the r must not exceed 6 inches (r ≤ 6 inches) in order to fit in the pizza box. On the other hand, the values of a represent the total area the pizza will occupy. In this case, the a must not exceed 113.10 square inches (a <span>≤ 113.10) </span>in order to house the pizza perfectly.

Someone plz help I don’t even know what this means

Vikentia [17]

What you wanna do here is use a calculator, as "e" in mathematics refers to the "e" on a calculator. The tricky part about this question is that the answer for the equation is the given percentage, NOT the value for "x". From there, plug in the multiple choice answers for "x" and see which one works!

In this case, A is the correct answer. B is absurdly large, so I omitted it immediately in the attached picture.
