The polar bear and the ice floe have a relative speed of 12 kilometers per hour. Given they're moving in opposite directions and the polar bear should end up 4 kilometers away, it would take approximately 0.33 hours or 20 minutes for the bear to reach this distance.
Explanation:The subject of this problem is relative speed. When two objects are moving in the opposite direction, their relative speed is the sum of their individual speeds. In this case, the ice floe is moving at 3 kilometers per hour and the polar bear is swimming at 9 kilometers per hour. So, their relative speed is 3 + 9 = 12 kilometers per hour.
The distance between the polar bear and the floe is 4 kilometers. To find out how long it will be before the polar bear is 4 kilometers away from the floe, you would divide the total distance by the relative speed. Therefore, the time would be 4 kilometers divided by 12 kilometers per hour equals 0.33 hours, or approximately 20 minutes.

Multiply the divisor and dividend by 10.
Multiply the divisor and dividend by 100.
Divide the divisor and dividend by 100.
Divide the divisor and dividend by 10.
The first step that Kenji must complete is option (B) multiply the divisor and dividend by 100 is the correct answer.
What is a division?A division is a process of splitting a specific amount into equal parts. The number to be divided by another number is called the dividend. The number by which we divide another number (dividend) into equal parts is called the divisor.
For the given situation,
Kenji wants to divide 48.6 by 0.15.
[tex]\frac{48.6}{0.15}[/tex]
Step 1:
To perform division, the first step is to make the divisor and dividend without decimals.
So multiply the divisor and dividend by 100.
⇒ [tex]\frac{48.6}{0.15}=\frac{48.6(100)}{0.15(100)}[/tex]
⇒ [tex]\frac{4860}{15}[/tex]
Hence we can conclude that the first step that Kenji must complete is option (B) multiply the divisor and dividend by 100 is the correct answer.

The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long and 103 inches wide. How many tiles, including parts of tiles, are needed to complete the job?
109 *103 = 11227 square inches
tile = 3^2 = 9 square inches
11227/9 = 1247.44 tiles are needed.
you can't buy a partial tile so you would need 1248 tiles
Answer:
We need 1248 tiles to complete the job.
Step-by-step explanation:
First we have to get the area of the room and the area of each tile
Area = long x wide
Room Area = 109 x 103 = 11227 square inches
Tile area = 3 x 3 = 9 square inches
To get how many tiles we need, we must divide the room area by the tile area
Q=11227/9= 1247,44 ≅1248
Triangle ABC is a right triangle
The length of BC is 5 units.
The area of ABC is ____ square units.
Answer:
50 square units.
Step-by-step explanation:
Given in the picture is a right angled triangle
The coordinates of A are (-9,10) and B are (7,-2) and C is (4,-6)
Given that BC = 5 units
AB = distance between A and B
=distance between two points (-9,10) and (7,-2)
=[tex]\sqrt{(-9-7)^2+(10+2)^2} =\sqrt{256+144} \\=20[/tex]
Thus if we consider BC as base then AB is the height
Area of triangle = 1/2 bh = 1/2 (5)(20)
= 50 square units
The area of the triangle is: 50 square units.
What is the Area of a Triangle?Area of a triangle = 1/2(base × height).
Given right triangle ABC:
Base = BC = 5 units
Height = AB = ?
Using the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find AB:
Let,
A(-9, 10) = (x1, y1)
B(7, -2) = (x2, y2)
Thus:
[tex]AB = \sqrt{(7 -(-9))^2 + (-2 - 10)^2}\\\\AB = 20 $ units[/tex]
Area of triangle = 1/2(5 × 20) = 50 square units.

Find the number of albums Floyd sold last month.
albums
Equation: [tex]a=\frac{644-200}{12}[/tex]
Albums: [tex]37[/tex]
Also, the verified tutor above me, is also correct, I just feel like my explanations and answers are much for informational and simplier than his
Explanation:First lets find out how many albums Floyd sold in a month to find out the amount of albums and how we solved it.
Let's take the [tex]\\644\[/tex] and subtract [tex]200\[/tex] from it, because he didn't make any albums or anything to get
Now that we have the amount of money that he gets from albums, we can divide this amount of money by [tex]12\[/tex] because that's the amount of money he gets from [tex]1[/tex] album. [tex]\frac{444}{12}=37[/tex]
Now we know how many albums he sells for a total of [tex]444\[/tex] plus the [tex]200\[/tex] he gets on a monthly rate.
Thank you for sticking with me on trying to learn how you got these answers instead of just staright-up cheating!The equation that determines the number of albums sold is:
200 + 12a = 644
The number of albums Floyd sold last month is 37
Word Problems on linear equations
Monthly base rate = $200
Pay on each album = $12
Number of albums = a
Total money earned = $644
The equation that determines the number of albums sold is:
200 + 12a = 644
Solve the equation above to get the number of albums sold
12a = 644 - 200
12a = 444
a = 444/12
a = 37

Which line represents the line of reflection in this diagram?
f
g
h
i
Answer: The correct option is (C) h.
Step-by-step explanation: We are given to select the correct line that represents the line of reflection in the given diagram.
We know that
A line of reflection is a line such that each point of the original figure and the image are equidistant from it.
In other words, we can say that the line of reflection is equidistant from the original figure and the image.
Now, from the figure, we can see that the line g is close on the figure on the left than that in the right. So, line g cannot be the line of reflection.
Line i is close the right figure on the upper half and it is close to the left figure on the lower half. So, line i also cannot be the line of reflection.
Line f cannot be the line of reflection because the shape of the figure is not same in both the sides of f.
The only line that is equidistant from both the figures is line h.
Thus, the line of reflection is line h.
Option (C) is CORRECT.
