when a number divides another number exactly the smaller number is called

Answers

Answer:

1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.

2) A number that divides a given set of numbers is called a common factor of the numbers.

Step-by-step explanation:

Just add 395 and 30 together.

Hope this helps. Pls give brainliest!

Answer:

425 ft

Step-by-step explanation:

So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.

Below is negative so 30 ft below is -30

Above is positive so 395 ft above is 395

the difference between 395 and -30 looks like this:

395- (-30)

So you can simplify to get this equation:

395+30

which is 425

So the difference between the snorkel and hike is 425 ft

The supplement of an angle is 4 times as large as the angle. Find the angle

Answers

Answer:

mark me barinlest

Step-by-step explanation:

supplement angles have sum = 180, complement angles have sum = 90

180-x = 4(90-x)

180-x = 360 -4x

3x = 180

x = 180/3

x = 60

answer measure of the angle = 60

Answer:

36°

Step-by-step explanation:

Supplementary angles sum to 180°.

Let the angle be x then the other angle is 4x.

Their sum is:

x + 4x = 1805x = 180x = 180/5x = 36

Question 3 options:

y−5=−23(x+9)

y−6=45(x−2)

y−2=−34(x−6)

y+6=45(x+3)

Answers

Answer:

Here’s the graph

Step-by-step explanation:

The equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:

y = (-3/4)x + 13/2

The correct answer is: Option C: y - 2 = -3/4(x - 6).

Here, we have to find the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1), we first need to find the slope (m) of the line using the formula:

[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]

where [tex](x_1, y_1) = (6, 2) ; (x_2, y_2) = (10, -1)[/tex].

m = (-1 - 2) / (10 - 6)

m = (-3) / 4

Now that we have the slope (m), we can use the point-slope form of the equation of a line:

[tex]y - y_1 = m(x - x_1)[/tex]

Using the point (6, 2):

y - 2 = (-3/4)(x - 6)

Now, simplify the equation:

y - 2 = (-3/4)x + 9/2

Finally, move -2 to the other side to get the equation in the point-slope form (y = mx + b):

y = (-3/4)x + 9/2 + 2

y = (-3/4)x + 9/2 + 4/2

y = (-3/4)x + 13/2

So, the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:

y = (-3/4)x + 13/2

The correct answer is: Option C: y - 2 = -3/4(x - 6).

Unfortunately the answer doesn't seem obvious to me. If i could have the answer as quickly as possible it would be very helpful. Thank you

Answers

Answer:

115%

Step-by-step explanation:

115% percent increase in usual value, I may guess see other answrrs too

Answer:

30%

Step-by-step explanation:

The percentage increase is calculated as

[tex]\frac{increase}{original}[/tex] × 100%

increase = £65 - £50 = £15 , then

percent increase = [tex]\frac{15}{50}[/tex] × 100% = 15 × 2% = 30%


Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:

Answers

Step-by-step explanation:

Graph 1 is a parabola and has 2 x points and a turning point

meaning it has a minimum and a maximum point.

conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.

Graph 1 is opposite to shown interpreted conclave so instead of --c++

we write  + + c - - and draw on quadrant 1 instead of quadrant 3

graph 2 is decreasing so instead of -+ c then + + it would show + -  c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.

Both graph 1 and 2 demonstrate minimum points for their f(x) for c.

so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.

The segment midpoint divides a segment into 2 halves by definition.

By the Segment Addition Postulate, you can add two adjacent segments to get the total length of the segment.

Given that RS=14

That means that 14 is 1/2 if the total segment length, so we know that segment RT is also = to 14 to make the other half.

We have two lengths that are 14, so we simply add them together to find the total segment’s length.

14+14=28.

The total line segment is 28.

Step-by-step explanation:

==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Let's test it

Initial: 10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

--

After 2 years

15,000 + (.5*15000)

Let's try our equation.
