60 people were asked the colour of their car and the pictogram shows the results.

a) 16 cars are red. Complete the key.

b) How many cars are silver?

KEY: One circle represents __ cars

Red = 4 circles
White = 3 circles and a half
Silver = 5 circles and 3/4
Grey ​= 1 circle and 3/4

Answers

Answer 1

The number of silver cars in the pictogram is 23.

How many cars are silver?

If 16 cars are red, then, each circle represents 4 cars.

If each circle represents 4 cars, then, each quarter of a circle represents 1 car

White car = 4 + 4 + 4 + 2

= 14 cars

Silver = 4 + 4 + 4 + 4 + 4 + 3

= 23 cars

Grey = 4 + 3

= 7 cars

Total cars = red + white + silver + grey

= 16 + 14 + 23 + 7

= 60 cars

It can therefore be concluded that silver cars is 23 in number.

Step-by-step explanation:

We know that oppostie sides of a rectange have to be equal

therefore

18=10+2x

solve for x

8=2x

x=4

Answer:

The value of x is 4

Step-by-step explanation:

For a given rectangle

Lenght (l) = 2y = 10

Breadth (b) = 10 + 2x = 18

Here,

2y = 10 ...(1)

10 + 2x = 18 ...(2)

Now, For x

10 + 2x = 18

2x = 18 - 10

2x = 8

x = 8/2

x = 4

Thus, The value of x is 4

A principal of $480 earns $108 interest in 5 years . what rate of interest was being paid?​

Answers

Answer:

4.5%

Step-by-step explanation:

Solving our equation

r = 108 / ( 480 × 5 ) = 0.045

r = 0.045

converting r decimal to a percentage

R = 0.045 * 100 = 4.5%/year

The interest rate required to

accumulate simple interest of $ 108.00

from a principal of $ 480.00

over 5 years is 4.5% per year.

Answers

In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.

However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).

Write an equation, in standard form, using the following given info: M = 10
and it passes through the point (6,2) *
-10x + y = -58
-10x + y = 58. -10x - y = -58
10x + y = -58

Answers

Given:

m = 10

The line passes through the point (6,2).

To find:

The equation of line in the standard form.

Solution:

If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of line is

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

The line passes through the point (6,2) and m = 10. So, the equation of line is

[tex]y-2=10(x-6)[/tex]

[tex]y-2=10x-60[/tex]

[tex]y-10x=-60+2[/tex]

[tex]-10x+y=-58[/tex]

Therefore, the correct option is A.

Answer:

theta = 22.6 degrees

Step-by-step explanation:

Here, we want to find the value of theta

To do this , we use the appropriate trigonometric identity

Let us identify the given sides of the triangle

we have the hypotenuse, which is the longest side of the triangle, given as 13 and the third side called the adjacent, given as 12

The trigonometric identity that relates the hypotenuse to the adjacent is the cosine

Mathematically;

cosine of an angle is the ratio of the adjacent to the hypotenuse

Thus, we have it that;

cos theta = 12/13

theta = arc(cos) 12/13

theta= 22.6

A sweater is on sale for 12% off. The sale price is $44.00. What is the original amount of the sweater?

Answers

Answer:  50 dollars

==================================================

Work Shown:

x = original price

y = sale price

d = discount = amount saved

d = 12% of x = 0.12x

y = x - d = x - 0.12x = 0.88x

Note how 0.88 = 88%, and this represents the percentage you have to pay if you get 12% off.

We're told the sale price is y = 44, so this leads to...

y = 0.88x

44 = 0.88x

0.88x = 44

x = 44/0.88

x = 50

The original price was $50

---------------------

Check:

If the original price was $50, then the amount you save is 0.12*50 = 6 dollars, which is the discount.

The sale price is 50-6 = 44 dollars which matches up with what your teacher gave you. The answer is confirmed.

A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 S

Answers

Complete Question:

A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 Seconds.

a. what acceleration is imparted to the paper?

b. if the mass of the paper is 0.003 kg, what force does the boxer exert on it?

c. how much force does the paper exert on the boxer?

Answer:

a. Acceleration = 454.55m/s².

b. Force = 1.36N

c. Force = -1.36N

Step-by-step explanation:

Given the following data;

Final velocity = 20m/s

Time = 0.044 seconds.

Since the paper is at rest, we know that it's initial velocity is equal to 0m/s.

a. To find acceleration;

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Substituting into the equation, we have;

[tex]a = \frac{20 - 0}{0.044}[/tex]

[tex]a = \frac{20}{0.044}[/tex]

Acceleration = 454.55m/s²

b. To find the force exerted by the boxer;

Mass = 0.003kg

Force = mass * acceleration

Force = 0.003 * 454.55

Force = 1.36N

c. To find the force exerted by the paper;

According to Newton's third law of motion which states that, for every action there is an equal and opposite reaction. Therefore, the paper exerts an equal but opposite force on the boxer.

Force = -1.36N

Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above

sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who

has hooked a fish that is 10 meters below the surface of the water.

a. Use positive and negative numbers to represent the locations in relation to sea level.

Scottie =

Top of the lighthouse =

The boat =

The fish =

meters

b. How far is Scottie from the fish?

Answer:

30 m ;

15 m ;

0 m;

40 m

Step-by-step explanation:

Scottie's position = standing on cliff

Height of cliff = 30 m above sea level

Height of lighthouse = 15 meters

Position of fish = 10m below sea level

Above sea level = positive, +

Below sea level = negative, -

Scottie's position = 30 m

Top of lighthouse = 15m

BOAT = surface of sea = 0m

Fish = - 10 m

Distance of Scottie from fish :

Scottie's position - Position of fish

30m - (-10)m

30m + 10m

= 40m

Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why?

(6, 20), because the point does not lie on any axis

(6, 20), because both lines pass through this point

(3, 11), because one of the lines passes through this point

(3, 11), because the point lies between the two axes

Answers

Answer:

(6,20) because both lines pass through this point

Step-by-step explanation:

To solve this you can use the substitution method.

Since both of them are equal to y, substitute one of the equations for y, that way you have x+14 = 3x+2. From here you continue to simplify.

Eliminate x from either side of the equation. For example, subtract x from the side that says "x+14". (Make sure you are also subtracting it from the other side of the equal sign as well.

Once you do this you should now have 14 = 2x+2

In order continue, you now have to get x by itself. So now subtract 2 from both sides of the equation. After doing this, you should have 12 = 2x

You then simplify x by dividing both sides by 2. This will get you x = 6

Now that you have the x-value, substitute that into either of the two equations (it is recommended you substitute it into both equations to make sure you have the correct x-value). For example: If I substitute x into Line C's equation, I will now have y = 6 + 14.

6 + 14 is 20, therefore you're y-value is y = 20
