aliya0001 [1]

let's take admission fee= z

8z+11z=17.50+21.25

19z=38.75

z=38.25/19

z=2.4 (aprox)

Or In case of Kiara 17.50 amount paid in 8 rides

.so 1 ride=17.50/8

=2.1875

same In case of mia

so 1 ride=21.25/11

=1.9318. 

but, they are not match so there is problem in your Questions.

PLEASE HELP!!! Two towns are 1100 miles apart. A group of hikers starts from each town and walks down the trail toward each othe
Vinvika [58]

Answer:

2.54 miles/hr

2.04 miles/hr

Step-by-step explanation:

<u>Given: </u> Distance between the two towns = 1100 miles

Difference between speeds = \frac{1}{2} miles/hr

Total time when they meet = 240 hours

<u>To find:</u>

Let distance traveled by first group = x miles.

Now, the distance traveled by second group = (1100-x) miles/hr

The relation between Speed, Time and Distance is given as:

\text{Speed =} \dfrac{\text{Distance}}{\text{Time}}

Let speed of first group = S_1

S_1 = \dfrac{x}{240}

Let speed of second group = S_2

S_2 = \dfrac{1100-x}{240}

As per question, S_1 = S_2 + \frac{1}{2}

\dfrac{x}{240} = \dfrac{1100-x}{240} + \dfrac{1}{2}\\\Rightarrow \dfrac{x}{240} - \dfrac{1100-x}{240} = \dfrac{1}{2}\\\Rightarrow \dfrac{x-1100+x}{240} = \dfrac{1}{2}\\\Rightarrow 2x - 1100 = 120\\\Rightarrow 2x = 1220\\\Rightarrow x = 610 ft

Now,

S_1 = \dfrac{x}{240}

Putting value of x:

S_1 = \dfrac{610}{240}\\\Rightarrow S_1 = 2.54\ miles/hr

Similarly, putting value of x in S_2:

S_2 = \dfrac{1100-610}{240}\\\Rightarrow S_2=\dfrac{490}{240}\\\Rightarrow S_2 = 2.04\ miles/hr

Plsplspls help i need 3 answers look at all three pics

Answers:

Angle A = 62.1 degrees

Angle X corresponds to angle A

The triangles are not similar

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

Explanation:

To find angle A, subtract the given angles B and C from 180 to get 180 - B - C = 180 - 60.8 - 57.1 = 62.1 degrees

Notice how none of the angles of triangle ABC have a measure of 59.1, so this means that angle Y cannot be congruent to any of A, B or C. This is why the triangles are not similar. We would need 2 pairs of congruent angles to use the AA (angle angle) similarity theorem.

If the triangles were similar, then we can say triangle ABC is similar to triangle XYZ. The letters A and X are the first letters mentioned of the trio of letters, which means that they correspond to one another.

Evaluate 81/4-615/32
Kaylis [27]

Answer:33/32

Step-by-step explanation:

81/4 - 615/32

32•4=128 to get a common denominator

Then whatever you do to the top you do to the bottom.

81•32=2,592

Then you would do

615•4=2,460

Now you have

2,592/128 - 2,460/128

Now you subtract

2,592-2460=132

You keep the denominator

132/128 and then simplify by dividing both numbers by four and you get

33/32
