Lets try
centimeter is about 1/2 of a inch

if 28 square cm, the book coould be about 4m by 7cm (aoub the size of a recipt)

if 28 square in the book could be about 4in by 7in (regular size)

I would guess 28 square INCHES (cm is too smal)

Answer:

6 inches.

Step-by-step explanation:

Let a represent side length of larger square.

We know that area of square is square of its side length, so area of the larger square will be $a^2$ .

The area of smaller square would be $4^2$ .

We will use proportions to solve our given problem.

$\frac{\text{Area of smaller square}}{\text{Area of larger square}}=\frac{4}{9}$

$\frac{4^2}{a^2}=\frac{4}{9}$

$\frac{16}{a^2}=\frac{4}{9}$

Cross multiply:

$4*a^2=16*9$

$\frac{4*a^2}{4}=\frac{16*9}{4}$

$a^2=36$

Take square root:

$a=\pm\sqrt{36}$

$a=\pm 6$

Since the length cannot be negative, therefore, the side length of larger square is 6 inches.

I need help on this question can anyone explain to me the answer?

raketka [301]

Answer:

Option C, $y = \frac{1}{10} x+1$

Step-by-step explanation:

We can find the correct answer by plugging in the x and y values of a point on the graph into each option, then finding the one that gives a true statement as a result.

For example, one point on the graph is (30,4). We can substitute 30 for the x and 4 for the y in option C's equation, $y = \frac{1}{10} x+1$ . Then, simplify:

$y = \frac{1}{10} x+1\\4 =\frac{1}{10} (30)+1\\4 = \frac{30}{10} +1\\4 = 3 +1\\4 = 4$

4 does equal 4, so when we substitute a point from the graph into this equation, the result is a true statement. Thus, option C is the answer.

Answer:

Step-by-step explanation:

x° + y° = 180°

2y° - 0.5x° = 180°

y° = 108°

Answer:

X=1

Step-by-step explanation:

Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).

Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)

Snorkel, mask, and flippers Slope intercept form: y = 2x + 10
