a ) 8 / 12
b) 6 / 12
c) 9 / 12
d) 10 / 12

Answers

Answer: a) 8/12

Step-by-step explanation:

Both numbers have to be the same for it to be equal: More info below.

The answer is a) because 8 divided by 2 is 4, and 12 divided by 3 is also 4.

It is not b) because 6 divided by 2 is 3, but 12 divided by 3 is 4.

Not c) because 9 divided by 2 is 4.5, and 12 divided by 3 is 4.

Not d) because 10 divided by 2 is 5, and 12 divided by 3 is 4.

Therefore, the answer is a) 8/12.

A reporter collected data on y, the current market value, in dollars, of a certain car for various years, x, after it had been purchased new. The equation below was fit to the data. y = 16,500 - 1,500x

Answers

Questions that followed :

What does the slope of the graph of this equation represent?

What does y-intercept of the graph of this equation represent?

Answer:

Kindly check explanation

Step-by-step explanation:

Given the model:

y = 16,500 - 1,500x

The slope = - 1500 ; this is a negative slope and means that the dependent variable will decrease with increase in the independent variable.

This means that, the market value of a car will decrease by 1500 per unit increase in year (a yearly fall of 1500 from the market value of cars per year after purchase).

The y - intercept is the value of y (market value) when x (number of years ) = 0 ; This means that the intercept value of 16500, is the initial prove of the car ; current value when the car hasn't been used.

Cara leaves her house at 10:03 and arrives at the library at 10:17. Irena leaves her house at 11:55 and arrives at the library at 12:06. Who takes longer to get to the library? How many minutes longer? Blank takes longer. She takes blank minutes longer

Answers

Answer: Cara takes longer to get to the library. She used 3 minutes more

Step-by-step explanation:

Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:

= 10.17 - 10.03

= 14 minutes

Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:

= 12.06 - 11.55

= 11 minutes

Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more

What is the height of the pyramid?

Answers

Answer:

4

Step-by-step explanation:

The slant height of the pyramid is marked as 5. If we drew and auxiliary 2D right triangle in the pyramid, this slant height would be the hypotenuse and one of the legs would be the height of the pyramid. The base leg would be equal to half of a side of the pyramid (3). Therefore, we can use the Pythagorean theorem to find the height ([tex]h[/tex]):

[tex]3^2+h^2=5^2,\\h^2=16,\\h=\boxed{4}[/tex]

Step-by-step explanation:

The given triangle is a right angled ∆ .The data given is ,

Base = x Hypontenuse = 23 Angle = 63° .

We can use ratio of cosine here , as ,

=> cos∅ = b/h

=> cos 63° = x/23

=> 0.45 = x/23

=> x = 23 × 0.45

=> x = 10.35

Hence the value of x is 10.35

What x and y equal to

Answers

Answer:

X = 4, Y = 3.

Explanation:

Since the length of side CK is equal to the length of WM, then you can make the equation 6y-4 = 18. then you just add 4 to each side and divide both sides by six to get 3. Same thing for the other equation. Angle (i think its an angle due to its placement) C is equal to angle M, so you can make the equation 3x + 7 = 19. Subtract seven from both sides then divide by 3 to get 4. Tell me if you have any questions :)

Answer and Step-by-step explanation:

We know the triangles are congruent, so if you were to flip one of the triangles onto the other, the will perfectly match up, allowing us to solve for x and y.

19 = 3x + 7

Subtract 7 from both sides.

12 = 3x

Divide each side by 3.

4 = x

14 = 6y - 4

Add 4 to each side.

18 = 6y

Divide each side by 6.

3 = y

x = 4

y = 3

62.8 ft

Step-by-step explanation:

Given,

Diameter = 20 ft ( from the diagram )

pi = 3.14

To find : Circumference ( circle ) = ?

Radius ( r )

= Diameter / 2

= 20 / 2

= 10 ft

Formula : -

Circumference ( circle ) = 2 pi r

Circumference ( circle )

= 2 x 3.14 x 10

= 2 x 31.4

Answers

Answer:

WY = 8

Step-by-step explanation:

We solve for above question using the Trigonometric function of Sine

sin θ = Opposite/Hypotenuse

Opposite = WY = x

Hypotenuse = 9

θ = 63°

Hence,

sin 63° = x/9

Cross Multiply

x = sin 63° × 9

x = 8.0190587177

Approximately x = 8

Therefore, WY = 8
