Step-by-step explanation:

Based on similar triangle;

14/49 = x+5/9x+1

Cross multiply

49(x+5) = 14(9x+1)

49x + 245 = 126x + 14

49x - 126x = 14 - 245

-77x = -231

x = -231/-77

x = 3

Hence the value of x is 3

Answer:

y = 20x

Step-by-step explanation:

y is the total amount that ricky will pay for the CDs.

x is the number of CDs that ricky bought.

so, in this case, if you replace the x by 600 :

y=20 x 600, witch means that the value of y is :

y = 12000 dollars.

Answer:

SSS similarity.

Step-by-step explanation:

AA, SAS, and SSA similarities means the triangle must have an angle, which it doesn't, so by process of elimination it is SSS similarity.

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

In the given figure, two lines AB and CD are parallel.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Consider, the triangle AOB and the triangle COD.

Here, AB║CD

∠BAO=∠CDO (Alternate interior angles)

∠ABO=∠DCO (Alternate interior angles)

By AA similarity criteria ΔAOB≈ΔCOD

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

Answer:

4 horses

Step-by-step explanation:

There are 2 elephants and 4 horses on one side. On the other, there are 12 horses. You can cancel 4 horses so now it's 2 elephants and 8 horses. To get the first side (2 elephants) to turn into one elephant, you need to divide by 2. So now, it is 1 elephant = 4 horses.

Answer:

4

Step-by-step explanation:

4 because you can write the problem as  2e+4h=12h then you subtract 4h from both sides and get 2e=8h then you divide by 2 to get e=4 so one elephant is as strong as 4 horses

h=horses

e=elephant

Answer:

The answer is A

Step-by-step explanation:

In order for it to be a function every x value has to have a different y value or every input has to have a different output.

Answer:

1. h = 2.4t + 4

2. 4 feet

3. 220 feet

Step-by-step explanation:

1. Write a linear model for the height, h, of the balloon as a function of the number of seconds, s that it has been raising.

Since the balloon rises at a constant rate, we find this rate by using the initial and final values of height and time at 5 seconds and 20 seconds respectively which are 12 feet and 52 feet respectively.

So, rate = gradient of line

= change in height/change  in time

= (52 ft - 16 ft)/(20 s - 5 s)

= 36 ft/15 s

= 2.4 ft/s

Now the equation of the line which shows the height is gotten from

(h - h')/(t - t') = rate

Using h'= 16 feet and t' = 5 s, we have

(h - 16)/(t - 5) = 2.4

h - 16 = 2.4(t - 5)

h - 16 = 2.4t - 12

h = 2.4t - 12 + 16

h = 2.4t + 4

where h is the height of the balloon above the ground and t is the time spent in the air in seconds.

2. What was the height of the balloon initially before the child let it go?

We obtain the initial height of the balloon before the child let go at time, t = 0 the time before the child let go.

So, substituting t = 0 into the equation for h, we have

h = 2.4t + 4

h = 2.4(0) + 4

h = 0 + 4

h = 4 feet

So, the height of the balloon before the child let go is 4 feet above the ground.

3. Use your model to predict the height of the balloon after 90 seconds.

We insert t = 90 s into the equation for h. So,

h = 2.4t + 4

h = 2.4(90) + 4

h = 216 + 4

h = 220 feet

So, the height of the balloon after 90 s is 220 feet above the ground.
