Choose the system of equations to solve the following: Tickets to a movie cost $7.25 for adults and $5.50 for students. A group

of friends purchased 8 tickets for $52.75. Determine the total number of adult and student tickets. *
A: 7.25a + 5.50s = 8 and a + s = 52.75
B: 7.25a + 5.50s = 52.75 and a + s = 52.75
C: 7.25a + 5.50s = 52.75 and a + s = 8

I assume in this item, we are to find at which step is the mistake done for the calculation of the unknown probability. 

For the possible number of arrangement of letter, n(S), the basic principles of counting should be used.
                       = 10 x 9 x 8 x 7 x 6 = 30,240

This is similar as to what was done in Meghan's work.

For the five tiles to spell out FACED, there is only one (1) possibility.

Therefore, the probability should be equal to 1/30,240 instead of the 1/252 which was presented in the steps above.

IceJOKER [234]

Answer:

1/15

Step-by-step explanation:

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

The amount of cereal she would have per day is calculated as:

5 days = 1/3 of the box

1 day = x

Cross Multiply

5 days × x = 1 day × 1/3 of the box

x = 1/3 ÷ 5

x = 1/3 × 1/5

x = 1/15 of the box

Question 11 of 11 -
alex41 [277]

Answer:

AA similarity

Step-by-step explanation:

Your question is not well presented.

See attachment

Given

Triangles ABC and DBE

Required

Which postulate supports the similarities of ABC and DBE

At the first transformation (180 degrees rotation) both triangles maintain SSS and AAA relationships. i.e <em>Side-Side-Side</em> and <em>Angle-Angle-Angle</em>

This is so because rotations do not alter the side lengths; neither does it alter the angles.

When the second transformation (dilation) takes place, the lengths of both triangles ABC and DBE become different because dilation alters side lengths.

However, angle measurements remain unaltered.

<em>Hence, AAA similarity answers the question</em>

The length of the tunnel is 460miles. If 1 inch represents 60 miles what is the length of the tunnel?
kotegsom [21]

Answer:

The length of the tunnel is 7.66667 inch

Step-by-step explanation:

We are given

1 inch =60 miles

now, we can find for 1 mile

so,

60 miles = 1 inch

we get

1mile=\frac{1}{60}inch

we are given

total length is 460 miles

so, we can multiply both sides by 460

460\times 1mile=460\times\frac{1}{60}inch

now, we can simplify it

460miles=7.66667inch

So,

The length of the tunnel is 7.66667 inch
