Answer:

1,092 cm²

Step-by-step explanation:

Smaller box:

Length = 24 cm

Wrapping paper = 936 cm²

Bigger box:

Length= 28 cm

Wrapping paper = x cm²

Box : wrapping paper = 24 cm : 936 cm²

Box : wrapping paper = 28 cm : x cm²

Equate both ratios to find x

24 : 936 = 28 : x

24/936 = 28/x

Cross product

24 * x = 936 * 28

24x = 26,208

x = 26,208 / 24

x = 1,092 cm²

Bigger box:

Length= 28 cm

Wrapping paper = 1,092 cm²

Solve the inequality:<br><br> 3/10 is greater than or equal to k - 3/5
Ostrovityanka [42]

To solve the inequality 3/10 is greater than or equal to k - 3/5, we must first set it up. Since 3/10 is greater than or equal to something, we will have a greater than or equal to symbol, with the 'mouth' pointing towards 3/10. Setting this up we get:

3/10 ≥ k - 3/5

Now we want to get k by itself on one side. We can do this by adding 3/5 to each side.

3/10 + 3/5 ≥ k

Simplify

9/10 ≥ k

How to find domain and range of a parabola?
german
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2

Which of the following is a like radical to mc001-1.jpg?
mixer [17]
You haven't provided the expression or the choices, therefore, I cannot provide an exact answer.
However, I'll try to help you understand the concept so that you can solve the question you have

Like radicals are characterized by the following:
1- They both have the same root number (square root, cubic root , ...etc)
2- They both have the same radicand (meaning that the expression under the root is the same in both radicals)

Examples of like radicals:
3\sqrt{xyz} and 7\sqrt{xyz}
\sqrt[5]{x^2y} and 3\sqrt[5]{x^2y}

Check the choices you have. The one that satisfies the above two conditions would be your correct choice

Hope this helps :)
