Answer:

1372 inches

Step-by-step explanation:

980/5=196

196*7=1372

The answer is 196 inches. Therefore the ant can travel 196 inches per minute.

An ant can travel at a constant speed of 980 inches every 5 minutes.

What you should do is find the distance traveled from this ant by in one minute so that we can get the accuracy from just dividing the total distance that was from this place to place distance.

Traveled distance from an ant in 1 min=980/5

Distance that was traveled by an ant is in 1 minute so 196.

Write an equation of the perpendicular bisector of the segment with the endpoints (8,10) and ( -4,2).
y =

Answers

Answer:

The required equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

Step-by-step explanation:

To find the equation of a line, the slope and y-intercept is required.

The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.

Given points are:

[tex](x_1,y_1) = (8,10)\\(x_2,y_2) = (-4,2)[/tex]

We will find the slope of given line segment first

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\= \frac{2-10}{-4-8}\\=\frac{-8}{-12}\\=\frac{2}{3}[/tex]

Let m_1 be the slope of perpendicular bisector then,

[tex]m.m_1 = -1\\\frac{2}{3}.m_1 = -1\\m_1 = \frac{-3}{2}[/tex]

Now the mid-point

[tex](x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\= (\frac{8-4}{2} , \frac{10+2}{2})\\=(\frac{4}{2}, \frac{12}{2})\\=(2,6)[/tex]

We have to find equation of a line with slope -3/2 passing through (2,6)

The equation of line in slope-intercept form is given by:

[tex]y = m_1x+b[/tex]

Putting the value of slope

[tex]y= -\frac{3}{2}x+b[/tex]

Putting the point (2,6) to find the y-intercept

[tex]6 = -\frac{3}{2}(2)+b\\6 = -3+b\\b = 6+3 =9[/tex]

The equation is:

[tex]y = -\frac{3}{2}x+9[/tex]

The equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is [tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex] and this can be determined by using the point-slope form of the line.

Given :

Endpoints  -- (8,10) and (-4,2)

The following steps can be used in order to determine the equation of the perpendicular bisector:

Step 1 - First, determine the slope of the line that passes through points (8,10) and (-4,2).

[tex]\rm m =\dfrac{2-10}{-4-8}[/tex]

[tex]\rm m = \dfrac{8}{12}[/tex]

[tex]\rm m = \dfrac{2}{3}[/tex]

Step 2 - So, the slope of the perpendicular bisector is given by:

[tex]\rm m'm = -1[/tex]

[tex]\rm m' = -\dfrac{3}{2}[/tex]

Step 3 - Now, determine the midpoint of the line that passes through the points (8,10) and (-4,2).

[tex]\rm x = \dfrac{8-4}{2}=2[/tex]

[tex]\rm y = \dfrac{10+2}{2}=6[/tex]

Step 4 - So, the equation of the perpendicular bisection that passes through the point (2,6) and has a slope -3/2 is:

[tex]\rm (y-6)=-\dfrac{3}{2}(x-2)[/tex]

Solve -4/5 divided by -2/3 then explain how you got your answer!!!! HELP ME WITH THISSS

Answers

Your answer will be -1 2/10, or -1 1/5 if you're looking for a simplified answer. My method is called KCF, or Keep Change Flip. First, you don't have to do anything with the -4/5. Next, you would want to change the division to multiplication. It is possible to just divide across, but changing it to multiplication is way easier and will save time. After that, you would switch -2/3 to -3/2. FLIPPING THE SECOND FRACTION DOES NOT MEAN THE NEGATIVE TURNS INTO A POSITIVE. Your answer would be 12/10, but we aren't done just yet. 10 goes into 12 once, now we have 1 2/10 left over. If you simplify you will get 1 1/5. So there you have it! I answered you question as best as I could and I hope this was helpful.

A French class has a total of students. The number of males is more than the number of females. How many males and how many females are in the class

Answers

Answer: Male = 25

Female = 19

Step-by-step explanation:

Your question isn't complete. Let's form another identical question and solve.

A french class has a total of 44 students. The number of males is 6 more than the number of females. How many males and how many females are in the class?

Let the number of females be x

Therefore males = x + 6

Total students = 44

Therefore, x + x + 6 = 44

2x + 6= 44

2x = 44 - 6

2x = 38

x = 38/2 = 19

There are 19 females

Males = x + 6 = 19 + 6 = 25
