Answer:

  x = 4

Step-by-step explanation:

Corresponding sides of similar triangles are proportional. This fact lets us write an equation that can be solved for x.

  AB/AC = DE/DC

  (6x -2)/5.5 = (2x +8)/4 . . . . . . substitute the given values

  4(6x -2) = 5.5(2x +8) . . . . . . multiply by 4×5.5

  24x -8 = 11x +44 . . . . . . . . eliminate parentheses

  13x = 52 . . . . . . . . . . . . . add 8 -11x

  x = 4 . . . . . . . . . . . divide by the coefficient of x

Answer:

10x + 4

Step-by-step explanation:

14-9 = 5

2x*5=10x

5+10x-1 = 10x+4

The volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.

The formula for calculating the volume of the cake is expressed as:

Volume of vanilla cake = 8in * 11in * 13in

Volume of vanilla cake = 1144in³

For the chocolate cake

Volume of the chocolate cake = 9.1in x 12in x 2 in

Volume of the chocolate cake = 218.4in³

Since the volume of vanilla cake is greater than the volume of chocolate cake, hence the vanilla cake gives you more to eat.

Answer:

y = 3/5x - 2

Step-by-step explanation:

Step 1:

y = mx + b       Slope Intercept Form

Step 2:

y = 3/5x + b     Input Slope

Step 3:

- 2 = 3/5 ( 0 ) + b    Input x and y

Step 4:

- 2 = 0 + b     Multiply

Step 5:

- 2 = b

Answer:

y = 3/5x - 2

Hope This Helps :)

The equation of the line in slope-intercept form is y = (3/5)x - 2.

To find the equation of the line in slope-intercept form (y = mx + b), where 'm' is the slope and 'b' is the y-intercept, we are given the slope (3/5) and a point on the line (0, -2).

Step 1: Use the point-slope form of the equation:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the given point (0, -2) and 'm' is the slope (3/5).

Step 2: Substitute the values:

y - (-2) = (3/5)(x - 0)

Step 3: Simplify:

y + 2 = (3/5)x

Step 4: Isolate 'y' by subtracting 2 from both sides:

y = (3/5)x - 2

Now, we have the equation of the line in slope-intercept form:

y = (3/5)x - 2

Answer:

Step-by-step explanation:

Answer:A

Step-by-step explanation:

The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.

The function is f(x) = 2x -1

The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.

Patel replaced f(x) by y, y = 2x -1

He then switched  x and y, x = 2y -1

The next step is to solve the equation for y.

2y = x +1

y = (x +1) /2

c) he would have to work 9 hours

5.

a) y=55+8x

b) 8*25=200

200+55=255 gallons

Step-by-step explanation:

I am not sure if I understand you right about what is needed.

I would understand we need the angle BAC (at A).

first of all, this is a right-angled triangle.

Pythagoras applies :

c² = a² + b²

with c being the Hypotenuse (side opposite of the 90° angle).

in our case that means

AC² = x² + y² = 4² + 6² = 16 + 36 = 52

AC = sqrt(52)

now we can use the law of sine to get the other angles.

a/sin(A) = b/sin(B) = c/sin(C)

with the sides and the corresponding angles being opposite.

in our case

y/sin(A) = AC/sin(B) = AC/sin(90) = AC

sin(A) = y/AC = 6/sqrt(52) = 0.832050294...

the angle A = 56.30993247...° ≈ 56.3°

Answer:

x = 1

Step-by-step explanation:

the important thing to know here is that if you do something to both sides of an equation (eg, add 2) the equation will still be equal.

- 9x - 17 = - 26

add 17 to both sides of the equation

-9x - 17 + 17 = -26 + 17

-9x = -9

divide both sides of the equation by -9

-9x/-9 = -9/-9

x = 1

Step-by-step explanation:

1. Calculate how many minutes it will take in total to reach work.

40 minutes to get ready

45 minutes to drive

40+45=85

85 minutes into hours =???

60 minutes = 1 hour

85-60=25

So, Jennifer will take 1 hour & 25 Minutes to go to work.

2. Calculate WHEN she will have to wake up to go to work.

10:10 is the time she HAS to be there.

so...

We know that it will take longer than 1 hour

so let's first remove 1 hour

that makes it, 9:10

now, let's remove 25 minutes

9:10, so 10 minutes gone

then 15 minutes remaining

60-15=45

so, Jennifer has to get movin' at 8:45am to reach her office at the right time.

Answer:

561/4

Step-by-step explanation:

Given that:

Height of first hill (f) = 255 feets

Height of second hill (s) = 11/20 the height of first hill

Height of second hill (s) = 11/20 of 255

Calculate the height of second hill:

s = 11/20 * 255

(11 * 255) / 20

= 2805 / 20

= 561 / 4

Height of second hill = 561/4

Answer:

The air the sound travels through cools down.

Step-by-step explanation:

I guessed a different answer on a test but the test said this was the right answer.

C. The air the sound travels through cools down will  cause a sound wave to slow down

A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air is called a sound wave

Liquid and solid will be more denser than air . So, the sound wave travel faster in them as compared to air

hence , option A. The sound passes from air into a liquid and  D. The sound passes from air into a solid. are wrong options for slowing down the speed of sound wave

Heat is a from of kinetic energy , molecules at higher temperature have more energy and can vibrate faster and allow sound wave to travel more quickly , hence  B. The air the sound travels through warms up.  is wrong answer

correct answer is C. The air the sound travels through cools down will  cause a sound wave to slow down as speed of sound as for each 1 degree Celsius that temperature decreases, the speed of sound decreases by 0.6 m/s .
