whole number?
ОА
39 lb
OB. 52 lb
OC 193 lb
OD. 180 lb

Answers

Answer 1

Answer:

OC 193 lb is correcte!

Answer 2

The person's weight, in pounds, when rounded to the nearest

the whole number is equal to [tex]1.9\times10^{2} pound[/tex]

We have given that, A pound is approximately 0.45 kilogram.

0.45 kg = 1 pound

Thus if 0.45 kg is equal to= 1 pound

87 kg will be equal to [tex]=\frac{1}{0.45} \times 87=1.9 \times 10^2 pound[/tex]

A= 3V/H

Step-by-step explanation:

V=1/3 AH

multiply 3 on both sides

How do I rewrite a quadratic into graphing form

Answers

Step-by-step explanation:

Standard form of a quadratic is f(x) = ax² + bx + c.

To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).

Then, plug back into the equation to find the y-coordinate of the vertex.  k = f(h).

Finally, the leading coefficient is the same as the standard form, a.

f(x) = a(x − h)² + k

Another method is to complete the square.

8. Why is it NOT useful to view science as a set of facts?

Answers

Answer:
(assuming this isn't actually for math?) but one reason is bc science shouldn't be always taken as fact. science can be wrong.

Explanation:
not all but many scientists are skeptical and won't accept anything without proof, and even when things are accepted as right they can still be wrong later. example: humans once believed the planets revolved around the earth and that the earth was flat (even, some people still believe the earth is flat today....) but both those things are generally unaccepted today.

science shouldn't be viewed as fact always, because accepting everything as fact will lead to misassumptions and false information. it's like we should never take things for granted

This is my honest opinion

Science is not just facts. Science, to me, is full of theories and hypotheses that can be proved wrong. Yes, a majority of it is actually factual, but in the future it may or may not be true.

Randy is four times as old as Kenneth and Randy is 36 years older than Kenneth
i) How old is Kenneth?
ii) How old is Randy?​

Answers

Answer:

Kenneth: 12 years old

Randy: 48 years old

Step-by-step explanation:

For this problem, we can use system of equations to solve. Let's use r for Randy and k for Kenneth.

Equation 1

r=4k

This equation comes from the first part, where Randy is four times as old as Kenneth.

Equation 2

r=36+k

This equation comes from the second part, where Randy is 36 years older than Kenneth.

Since we have r=, we can use substitution method.

4k=36+k                   [subtract both sides by k]

3k=36                       [divide both sides by 3]

k=12

Now that we have found k, we can plug that into any equation to find r.

r=4(12)                      [multiply]

r=48

Now, we know that Randy is 48 years old and Kenneth is 12 years old.

A football team loses 8 yards on each of 4 consecutive plays. Find the total change in yards from where the team started. pls help fgkogijriojg

Answers

Answer:-32

Step-by-step explanation:

You times the two numbers and add a negative sign in front of it

8 would be a negative in this situation and 4 would be a positive. So the problem would look like this:

-8 x 4 = ?

For this particular problem, we would do 8 x 4 which would equal 32. Then we would try to find which one has the greater absolute value.

Absolute Value:

4 = 4

-8 = |8|

Since -8 has the greater absolute value, the answer would be negative.

The Answer: -32

Find k so that the line through(k-1,k+2) and (4,-1) is perpendicular to the line through (-3,2) and (2,5).

Answers

Answer:

k = 2

Step-by-step explanation:

Perpendicular lines have slopes opposite reciprocal

Formula to find a slope:

m = (y₂-y₁)/(x₂-x₁)

Coordinates of the first line:

(k-1, k+2) and (4, -1)

Coordinates of the second line:

(-3, 2) and (2, 5)

Slopes of the lines:

m₁ = (-1 - k -2)/(4 - k + 1) = - (k + 3)/-(k -5) = (k + 3)/ (k - 5)m₂ = (5 - 2)/ (2 + 3) = 3/5

Since m₁ = - 1/m₂, we have:

(k + 3)/ (k - 5) = - 5/33(k + 3) = -5(k - 5)3k + 9 = - 5k + 253k + 5k = 25 - 98k = 16k = 2

So the answer is 2

Find the distance between each pair of points (-6,-10) , (-2,-10)

Answers

Answer:

4 units

Step-by-step explanation:

Use the distance formula, d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex], where (x1, y1) and

(x2, y2) are 2 points

Plug in the points given

d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

d = [tex]\sqrt{(-6 + 2)^2 + (-10 + 10)^2}[/tex]

d = [tex]\sqrt{(-4)^2 + (0)^2}[/tex]

d = [tex]\sqrt{16 + 0}[/tex]

d = [tex]\sqrt{16}[/tex]

d = 4

So, the distance between the points is 4 units

The distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.

What is a distance formula?

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

It is given that:

The points are (-6,-10) , (-2,-10)

Using distance formula:

[tex]\rm d=\sqrt{(-2-(-6))^2+(-10-(-10))^2}[/tex]

d = √16

d = 4 units

Thus, the distance between each pair of points (-6,-10) , (-2,-10) is 4 units after using the distance formula.
