Answers

the 20% of $43.00 is 8.60 which means 

43.00+8.60 = 51.60

Meal= $43.00
Tip= 20%

Total= Meal + (Meal * 20%)

= $43 + ($43 * 20%)
convert % to decimal (20% ÷ 100 or simply move decimal 2 places left)

= 43 + (43 * 0.20)
multiply inside parentheses

= 43 + 8.60

= $51.60 total


ANSWER: The total, including a 20% tip, is $51.60.

What is the area of the shaded region to the nearest tenth of a foot?

Part a) Explain what formulas you will use to find the area of the shaded area.

Par b) Explain how you find the area of the shaded region. What was your thought process?

Answers

a) The shaded region is that portion of the rectangle that is not in the circle. You need the formulas for the area of a rectangle and a circle.
 Area of rectangle = length*width
 Area of circle = (π/4)*diameter²

b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
 Shaded Area = Area of rectangle - Area of circle
 Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
 Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²

What is the solution of the system? y = -8x - 2 and y = -6x + 4

A. (-3, 22)
B. (-8/3, 1/22)
C. (-14/3, 6/22)
D. (3/14, - 6/14)

Answers

Plug the x and y coordinates into those equations and whichever one makes sense for BOTH of the equations is a solution
Equation 1:  y = - 8x - 2    

Equation 2: y = - 6x + 4

Equation both equations, we get:

- 8x - 2= - 6x + 4

-8x + 6x = 4 + 2

-2x = 6

x = -3

Using the value of x in first equation, we get:

y= -8(-3) - 2 = 24 - 2 = 22

So, the solution to the given equations is (-3, 22)

So, the answer is option A

A parallelogram is a quadrilateral where there are no right angles, the vertical sides are parallel to each other (usually slanted), and the horizontal sides are parallel to each other. All of the sides can be congruent but not always; the lines parallel to each other must also be congruent to each other though.

It takes a ship 3 hours to cover 72 km with the current and 4 hours against the current. Find the speed of the ship in still water and the speed of the current.

Answers

x- speed of the ship in still water
a- speed of current
(x+a)- speed with current
(x-a) - speed against current

(x+a)*3=72
(x-a)*4=72

      x+a=24
+    x-a=18
    2x    =42
      x = 21

x+a=24,    21+a=24,    a=3

The speed of the ship in still water = 21 km/h, 
the  speed of the current =3 km/h.

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (look at the image below)

The dependent variable is distance, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.
The dependent variable is time, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is time, the equation is y = 20x, and the dragonfly will travel 480 miles.

Answers

40/2 = 20
so 
y = 20x

y = distance (miles) and x = time (hours)
so if x = 24 then y = 20x = 20(24) = 480

answer
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles. 

Answer:

The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20[/tex]

Therefore, the equation is [tex]y=20x[/tex], which shows a direct proportion between variables.

Now, in 24 hours, it would travel

[tex]y=20(24)=480[/tex]

It would travel 480 miles.

Therefore, the right answer is the second choice.

a traffic light on a busy north-south street is programmed according to this pattern: green for 4 minutes followed by red for 2 minutes. mr gomez goes through this intersection on his way to an from work everyday. last week, he kept a record of the number of times it was green as he approached the intersection and the number of times he had to stop because the light was res. his record is as follows green green red green green green green green green green, what is the therorerical probability that the light will be green each time mr gonez approaches the intersection

Answers

It would be 2/3.

The theoretical probability is the expected amount of times that the light would be green. The light is green for 4 minutes and red for 2 minutes for each series. That means 4 out of the total 6 minutes are green.

4/6 = 2/3

What number would come next in the sequence above, 4, 7, 10, or 12? Explain your answer.

Answers

The next number in the sequence will be 12.

Explanation

The given sequence is:   8, 15, 14, 9, 1, 6, 3

If we express these numbers in words, then we can see that the words are in alphabetical order, like....

Eight,  Fifteen,  Fourteen,  Nine,  One,  Six,  Three

There are two numbers 10 and 12 in the options which starts with letter 'T' , but  alphabetically 'Twelve' will be the next number after 'Three'

So, the next number in the sequence will be 12.

A 35-meter length of cable is cut into pieces that measure 1.25 meters each. Into how many pieces is the cable cut?

Answers

It can be cut into 28 pieces. 
Final answer:

The cable is cut into 28 pieces.

Explanation:

To find how many pieces the cable is cut into, we can divide the total length of the cable by the length of each piece. In this case, the total length of the cable is 35 meters and the length of each piece is 1.25 meters.

Dividing 35 meters by 1.25 meters gives us:

35 m ÷ 1.25 m = 28 pieces

Therefore, the cable is cut into 28 pieces.

What is eight and nineteen thousandths in decimal form

Answers

8.019!
Hope this helps!

Decimal form of eight and nineteen thousandths is 8.019.

Eight and nineteen thousandths in decimal form is written as 8.019.

To represent this in decimal form, we can think of the place value chart: 8 (whole number part), 0 (tenth place), 1 (hundredth place), and 9 (thousandth place).

Therefore, 8.019 is the decimal form of eight and nineteen thousandths.

Write an equation for a line g(x) perpendicular to f(x) = 4x − 5 and passing through the point (4, 20). plz.....

Answers

The slopes of perpendicular lines are negative reciprocals.The slope of the given line is 4.The slope of the perpendicular is -1/4.
Now we need to find the equation of a line that has slope -1/4 and passes through the point (4, 20).
We use the point-slope form of the equation of a line, where m = slope, and the point is (x1, y1).
y - y1 = m(x - x1)
y - 20 = -1/4(x - 4)
-4y + 80 = x - 4
x + 4y = 84

Final answer:

The equation for the perpendicular line g(x) is g(x) = (-1/4)x + 21, found by using the negative reciprocal of the original slope and the point-slope form of a line.

Explanation:

To find the equation for a line g(x) that is perpendicular to f(x) = 4x - 5 and passes through the point (4, 20), we need to determine the slope of the perpendicular line and then use the point to find the specific equation.

Since the slope of the line represented by f(x) is 4, the slope of any line perpendicular to it will be the negative reciprocal, which is -1/4.

Now, we can use the point-slope form of a line equation, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through.

Substituting the given point and the slope into the point-slope form, we get:

y - 20 = (-1/4)(x - 4)

Expanding this we have:

y - 20 = (-1/4)x + 1

Adding 20 to both sides to solve for y gives us the final equation of line g(x):

g(x) = (-1/4)x + 21
