DF= 33

Step-by-step explanation:

The ratio is equal to 6:5:1 Which can be changed into 18:15:3

Since DE=18 and EF=15 you simply add and = 33

Answer:

df=33

Step-by-step explanation:

Answer:  speed = 17m/s

              time taken = 3min = 3 x 60 = 180 seconds   (1min = 60sec)

distance = ST

               = speed x time

                = 17 x 180

= 3060m

Given:

Original price of a TV = $499

Price increased by 15%.

To find:

The new price of the TV.

Solution:

According to the question,

New price of the TV = Original price + 15% of its original price.

[tex]\text{New price of the TV}=499+\dfrac{15}{100}(499)[/tex]

[tex]\text{New price of the TV}=499+74.85[/tex]

[tex]\text{New price of the TV}=573.85[/tex]

Therefore, the new price of the TV is $573.85.

Now,

8% of x = Rs.640

or, 8/100*x=Rs. 640

or, 8x\100=Rs.640

or, 8x=Rs.640*100

or, x= 64000/8

Answer:

Water temperature in an ocean varies inversely to the water’s depth. Between the depths of 250 feet and 500 feet, the formula

T

=

14

,

000

d

gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface. Consider the Atlantic Ocean, which covers 22% of Earth’s surface. At a certain location, at the depth of 500 feet, the temperature may be 28°F.

The related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]

For inverse variation, if a is inversely proportional to b. This is expressed as:

[tex]a \alpha \frac{1}{b}[/tex]

Introducing the constant of variation will give;

[tex]a=\frac{k}{b}[/tex]

Applying the concept to the question:

If the temperature t at which water boils is inversely proportional to the number of feet F, this is expressed as:

[tex]t \alpha \frac{1}{F}[/tex]

[tex]t=\frac{k}{F}[/tex]

Hence the related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]

Answer: 11.25 hours

Step-by-step explanation:

From the question, we are informed that every 3 days Ronnie spends 1.5 hours on homework and 2.25 hours on chores.

At this rate number of hours that he will spend on homework and chores in 9 days will be:

= 9/3 [1.5 hours on homework + 2.25 hours on chores]

= 3 [1.5 hours on homework + 2.25 hours on chores]

= 4.5 hours on homework and 6.75 hours on chores]

Total hours = 4.5 + 6.75 = 11.25 hours

Step-by-step explanation:

Answer:

Step-by-step explanation:

Lets denote number of floor tickets by x and

Lets denote number of balcony tickets by y as shown in the figure in the question

so, floor tickets are sold for $15 each which means number of x tickets would be sold by $15 multiplied by x which means 15x and balcony tickets are sold for $12 each which means number of y tickets would be sold by $12 multiplied by y which means 12y furthermore it says they want to make at least $3000 which would mean they want to make at least $3000 or higher meaning ≥3000 so the inequality would be

a) [tex]15x+12y\geq 3000[/tex]

b) The ordered pair A we can see that A is the y-intercept which means the point A can also be written as (0 , y) so we put this point into our equation

15x + 12y = 3000 which is the boundary line. So here goes,

[tex]15x+12y=3000\\15(0)+12(y)=3000\\12y=3000\\y=3000/12\\y=250\\[/tex]

so our y-intercept is 250 which means Point A is (0 , 250)

c) They should  shade the area above the boundary line because in this context the band that is playing wants to make at least $3000 which means they want to make more than $3000 . So when a ≥ sign appear we shade the area above the boundary line and when the ≤ sign appears we shade the area below the boundary line. If it were in the question the bands wants to make at most $3000 then the ≤ would appear.

I have attached a graph to clearly visualize the solution as well.

Yes, The preimage and the image have the same shape and size.

The reflection of an object across an axis is creating an image that has the same shape and size.

A triangle ABC is reflected over the x-axis to form A'B'C'

When reflected over an axis, the coordinate of the other axis is changed to its additive inverse.

(x,y)-------> (x,-y)

Let the coordinate of the triangle is  (1,1),(3,5),(3,1)

The image of the triangle when reflected over x-axis is

(1,1),(3,5),(3,1)       ------------->    (1,-1),(3,-5),(3,-1)

The shape of a right-angled triangle is the same in the image, the length of the side is same, it is just an image of the same shape and size.

Answer:

a. 176 feet b. 2640 feet

Step-by-step explanation:

a. Since the diameter of the Ferris wheel is D = 56 feet, the distance Toni travels in one revolution is the circumference of the Ferris wheel, C = πD.

So C = 22/7 × 56 ft = 22 × 8 ft = 176 feet

b. The distance traveled in 15 revolutions is thus D' = 15 × distance of one revolution = 15 × 176 = 2640 feet

Answer:

9.025 inches

Step-by-step explanation:

Let the length be represented by:

[tex]L = mt+L_0[/tex]

Where [tex]L[/tex] is the length of candle at time [tex]t[/tex]

[tex]m[/tex] is the rate at which the candle is burning.

And [tex]L_0[/tex] is the initial length of the candle.

As per the question statement, let us put the given values in the equation.

[tex]11.2 = m\times 33 + L_0 .... (1)\\10.75 = m\times 51+L_0 ..... (2)[/tex]

Subtracting (1) from (2):

[tex]0.45 = -18m\\\Rightarrow m = -0.025[/tex]

Putting the value of [tex]m[/tex] in the equation (1):

[tex]11.2 = -0.025 \times 33+L_0\\\Rightarrow L_0 = 12.025[/tex]

Therefore, the equation becomes:

[tex]L = -0.025t + 12.025[/tex]

Now, we have to find the height of candle after 2 hours.

2 hours mean 120 minutes.

[tex]L = -0.025 \times 120 + 12.025\\\Rightarrow L = 9.025\ inches[/tex]

Therefore, the height of candle is 9.025 inches.

Answer:

1 it's and equilateral

Answer:

1 and 4

Step-by-step explanation:

An Equilateral triangle has equal sides.

an Acute triangle has angles that are less than 90

Answer: 40

Reason: Okay, so we can see that the line is travelling in a straight line. When we look closely at the graph, we can see that for every two minutes, it makes 80 bottles, and so on and so fourth. We know it makes 80 bottles in two minutes, so let's divide it by two to find out how many bottles it makes in one minute. (Equation for this = 2x = 80) After dividing, we find out that the machine makes 40 bottles per minute

Check: 40 bottles, and multiply it by 2, and we get 80 bottles per two minutes, and that's correct.
