Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
Choice D
Step-by-step explanation:
When you find the unit price it will be easier to eliminate the other choices and to find the unit price I found the easiest numbers to work with, so if we do $5 divided by 2 lbs it'll give us $2.5 and that's our unit price. Then for the graphs we are left with choices C and D. So all we have to do is see which one has the line passing through point (2,5) which stands for 2 oranges and $5.

10 : 12 and 11 : 13
5 : 6 and 20 : 24
5 : 6 and 11 : 13
Answer:
10 : 12 is equivalent to 5 : 6 and 20 : 24.
Step-by-step explanation:
You can divide and multiply the ratio by 2 to get an equivalent ratio.
The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24 Therefore, option (C) will be correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
As per the given ratio, 10:12.
Divide numerator and denominator by 2
(10/2):(12/2) = 5:6.
Multiply the numerator and denominator by 2
(10×2);(12×2) = 20:24
Hence "The ratio which is equivalent to 10: 12 are 5: 6 and 20: 24".

Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function l(x)=4x+9, where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x)=2x+5 .
Answer:
8x^2+38x+45 so B
Step-by-step explanation:
i got it right on the test
The required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.
Given that,
Dan is tiling his rectangular, concrete porch with square, porcelain tiles. The length of the porch is represented by the function l(x)=4x+9, where x is the side length, in feet, of each tile. The width of the porch is represented by the function w(x)=2x+5.
The surface area of any shape is the area of the shape that is faced or the surface area is the amount of area covering the exterior of a 3D shape.
Here,
Length of the porch = 4x + 9
Width of the porch = 2x + 5
area of the porch A(x) = (4x + 9) (2x + 5 )
= 8x² + 20x + 18x + 45
= 8x ² + 38x + 45
Thus, the required equation of the function that represents the area of the porch is A(x) = 8x² + 38x + 45. Option D is correct.

It takes 2 workers 10 minutes to plant 3 trees. If all workers plant trees at the same constant rate, how many minutes will it take 4 workers to plant 24 trees?
40
if it takes two workers 10 minutes to plant 3 trees,then it will take 4 workers 5 minutes to plant 3 trees.3÷24=8,then 5×8=40
If it takes 2 workers 10 minutes to plant 3 trees then it will take 4 workers 40 minutes to plant 24 trees.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The rate at which each worker plants trees.
If two workers can plant 3 trees in 10 minutes, then one worker can plant 3/2 trees in 10 minutes
One worker can plant 1.5 trees in 10 minutes, or 0.15 trees per minute.
Now, we can use this rate to find how long it will take 4 workers to plant 24 trees.
Since each worker plants at a rate of 0.15 trees per minute
Four workers will plant at a combined rate of 0.15 x 4 = 0.6 trees per minute.
To plant 24 trees at a rate of 0.6 trees per minute, we can use the formula:
time = (amount of work) / (rate of work)
Plugging in the values, we get:
time = 24 / 0.6 = 40
Therefore, it will take 4 workers 40 minutes to plant 24 trees.

A plane traveled 336 miles to Carson City and back. The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours. What is the speed of the plane in still air? What is the speed of the wind?
Answer:
Thus, train speed = 70 mph while wind speed is. y = 14 mph
Step-by-step explanation:
Let x = speed of the plane in mph.
Let y = speed of wind in mph.
We are told that The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours.
Formula for distance is;
Distance = speed × time
Thus;
(x + y)4 = 336
(x + y) = 84 - - - - (1)
Also;
(x - y)6 = 336
Divide both sides by 6
(x - y) = 56 - - - (eq 2)
Add eq 1 and 2 to give;
2x = 84 + 56
2x = 140
x = 140/2
x = 70 mph
Plug in 70 mAh for x in eq 1.
(70 - y) = 56
y = 70 - 56
y = 14 mph
Thus, train speed = 70 mAh while wind speed is. y = 14 mph
x + y divided by y; use x = 9, and y = 10

The manager of hockey team says that the probability that team win the next match is 0.5 and the probability it will lose is 0.2. Find the probability that the team will: a ) not win b) not lose c) not draw
Answer:
Step-by-step explanation:
The team draws with a probability of 1 = (0.5 + 0.2) = 0.3
If the team does not win then it loses or draws.
Loosing = 0.2
Draw := 0.3
P(not win) = 0.2 + 0.3 = 0.5
======================
Not lose means wins or draws.
P(not lose) = 0.5 + 0.3 = 0.8
======================
Not Draw means wins or loses
P(not draw) = 0.5 + 0.2 = 0.7
Of course all of these could be done more directly.
P(not win)= (1 - win) = 1- 0.5 = 0.5
P(not lose) = ( 1 - lose) = 1 - 0.2 = 0.8
P(not draw) = (1 - 0.3) = 0.7
