A school bus has 25 seats, with 5 rows of 5 seats. 10 students from 2nd grade and 5 students from 1st grade travel on the bus. How many ways can the students be seated if the 2nd graders have to sit in the first two rows?

Answers

Answer 1

Answer:

(Answer in attachment, explanation below)

Step-by-step explanation:

The answer is B. 5P5 x 20P15.

This is because to make the second grade students to sit in the first row we have 5 seats and 5 students so we will permute the 5 students to those 5 seats. So 5P5.

Now we are left with 20 seats and 15 first grade students so we can simply permute those 15 students into those 20 seats. So 20P15.

Finally using the counting rule principle we will multiply both of these so 5P5 x 20P15.

No. of students from first grade = 15

No. of students from second grade = 5

There are 5 rows of seats

Each row contains 5 seats

Total seats = 25

No. of ways for second-grade students occupy the first row(i.e first 5 seats) =  

Remaining seats = 20

No. of students from first grade = 15

So, No. of ways for first-grade students occupy remaining seats =  

So,  No. of ways for the students can be seated if all of the second-grade students occupy the first row =  

So, Option B is true

Hence No. of ways for the students can be seated if all of the second-grade students occupy the first row is

In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex].

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.

Answers

Answer:

x = 7

Step-by-step explanation:

The image below shows the relationship between secants chords and tangents.

Imagine that the letters in the image represent the numbers in the actually problem

E would equal 9

C would equal 12

and A would equal x

We would then use the same formula C² = E * ( E + A ) to solve for x , but once again instead of using letters we use the numbers in the problem

We would have 12² = 9( 9 + x )

we now solve for x

Step 1 simplify and distribute

12²=144

9 * 9 = 81

9 * x = 9x

we would then have 144 = 81 + 9x

step 2 subtract 81 from each side

144 - 81 = 63

81 - 81 cancels out

we now have 63 = 9x

step 3 divide each side by 9

63 / 9 = 7

9x / 9 = x

we're left with x = 7
