Answer:
-5 7/8 ft (Answer D)
Step-by-step explanation:
Note that 5.875 ft is the same as 5 7/8 ft.
The diver is initially 5 7/8 ft beneath the water surface, so we give that 5 7/8 ft the negative sign:
-5 7/8 ft represents the diver's position in relation to the surface.
The driver's position in relation to the surface before swimming to the top is represented by D. -5 7/8 feet. This is because in this scenario, a negative number signifies underwater depth.
Explanation:In mathematics, the term 'relation' is often used in the context of functions and refers to the way two sets of numbers are interconnected. In your scenario, a negative number is used to signify the driver's position underwater, while a positive number indicates their position above water. Therefore, if the diver swims 5.875 feet up to the surface, this would mean their original position was -5.875 feet. When expressed in decimal form, this would be -5.9, and when expressed in fractions, it would be -5 7/8 feet. Hence, the correct answer would be D. -5 7/8 feet.

plz help this is fifth grade math and it is using compensations and it is hard
After solving the given mathematical expression which is $5.40 + $8.70 + $6.30 , we get value equal to $20.40
What is addition ?
The process of adding two or more numbers together or combining things into one group is known as addition.
The given arithmetic expression is $5.40+$8.70+$6.30.
Let's solve the given mathematical expression.
To add decimal numbers , place the decimal point in line with the specified decimal points, align the decimal numbers in accordance with their place values. If we look at the given decimals, we can see that they are like decimals because they have two digits after the decimal point. Therefore, we will arrange them in the proper sequence and perform standard addition rule.
i.e.,
5.40 + 8.70 + 6.30
We can write this as sum of :
= (5+8+6) + (0.40 + 0.70 + 0.30)
Now , solving to get the value :
= (19) + (1.40)
= $20.40
Therefore, after solving the given mathematical expression which is $5.40 + $8.70 + $6.30 , we get value equal to $20.40

P(-2,2.5) Q(1.4,4) Find the midpoint
Answer:(-0.3,3.25)
Step-by-step explanation:
The midpoint of P(-2,2.5) and Q(1.4,4) is ( -0.3, 2.25)
What is Midpoint?A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.
Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,
M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2
Given P(-2,2.5) and Q(1.4,4)
So the midpoint = [(-2 + 1.4)/2, (2.5 + 4)/2]
The midpoint = [(-0.6)/2, (4.5)/2]
The midpoint = ( -0.3, 2.25)
Hence, the midpoint of P(-2,2.5) and Q(1.4,4) is ( -0.3, 2.25).

Karl is investigating two transformations.
Karl claims that a reflection over the line y=1 transforms a point (x,y) to the point (2−x,y). For example, (1,1) is reflected to (1,1).
Karl makes a second claim that a reflection over the line y=x transforms a point (x,y) to the point (y,x). For example, (2,2) is reflected to (2,2).
Which statement correctly classifies Karl’s claims?
A
Karl is correct regarding the first claim, but a reflection over y=x carries (x,y) to (x,y).
B
Karl is correct in both of his claims because each provided example supports the associated claim.
C
Karl is incorrect in both of his claims because neither example is enough to prove the associated claim.
D
Karl is incorrect as a reflection over line y=1 carries (x,y) to (x,2−y) but is correct in his second claim.

Answer:
Equation of the line is y=-x+3
Rewritten as an inequality is y ≤ -x+3
Step-by-step explanation:
You find the slope by doing rise over run which ends up being -1/1, so just -1.
The y-intercept is 3.
Slope intercept form is y=mx+b, so y=-x+3 is the answer in slope intercept.
Then ≤ is used because the line is going down and it's shaded to the left, also the line isn't broken, it's solid which means it's equal to, so it would be less than or equal to.

an average person has 6x10 2power times as many red blood cells as white blood cells. A small sample of blood has 7x10 3power white blood cells. about how many red blood cells are in the sample
Answer:
4.2×10to the 6th or 4,200,000
Step-by-step explanation:
First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.
6×10to the 2 * 7×10to the 3rd
42 × 10to the 2+3
42×10to the 5th
Something else you need to know is your matissa cant be higher than 10
So:
4.2 × 10to the 6th is your answer
The sample contains 42 × 10⁵ red blood cells.
What happens when same base is multiplied ?When same base is multiplied their powers gets added.
For example - a×a×a×a×a×a = a⁶.Here a has nothing in it's power means it has 1 to it's power.
According to the given question
For every 1 while blood cells an average person has 6x10² times as many red blood cells.
A small sample of blood contains 7 × 10³ white blood cells.
∴ The amount of red blood cells in the sample is
= (7 × 10³)(6× 10²) red blood cells.
= (7×6)(10³×10²)
= 42 × 10⁵ red blood cells.

To get -18, we can use the factors
2 times -9 = 18How to fill the blanksTo find two numbers that multiply to give -18, we need to consider pairs of factors of -18. The factors of -18 are:
1 and -18
2 and -9
3 and -6
So, the pairs of numbers that multiply to give -18 are:
1 * -18 = -18
2 * -9 = -18
3 * -6 = -18
Therefore, -18 can be expressed as the product of various combinations of these pairs, such as (-2) * 9, (-3) * 6, and so on.

Estimate 3,182 multiply by 5
Estimate the product of 3,182 multiplied by 5 by rounding to the nearest hundred, resulting in an estimation of 16,000.
Explanation:To estimate the product of 3,182 multiplied by 5, we can round 3,182 to the nearest hundred to make the multiplication simpler.
Rounding 3,182 to the nearest hundred gives us 3,200.
We then multiply 3,200 by 5:
3,200 x 5 = 16,000
This estimated product is not an exact answer but gives us a reasonable approximation that is easy to calculate mentally or on paper.
