Answer:

There are 102 students in each period.

Answer:

-11 yd/s

Step-by-step explanation:

We basically have to the find slope between the given points

Let h(t)₁ = 0

     h(t)₂ = 33

      t₁ = 6

      t₂ = 3

We have to find the change in distance (h(t)₁ - h(t)₂) then divide it by the change in x (t₁ - t₂)

6 - 3 = 3

This means the change of x is 3

0 - 33 = -33

This means the change in distance is -33

Now divide -33 by 3

-33 ÷ 3 = -11

The order of selecting the balls is an illustration of permutation and combination

The given parameters are:

The possible number of winning numbers in any order is calculated using the following combination expression

[tex]n = ^{69}C_5 * ^{24}C_1[/tex]

This gives

[tex]n = 11238513* 24[/tex]

Evaluate the product

[tex]n = 269724312[/tex]

Hence, the possible number of winning numbers is 269724312

When order is important, we make use of permutation.

So, we have:

[tex]n = ^{69}P_5 * ^{24}P_1[/tex]

This gives

[tex]n = 1348621560* 24[/tex]

Evaluate the product

[tex]n = 32366917440[/tex]

Hence, the possible number of winning numbers in order is 32366917440

To solve this question, we have to add two polynomials together. The polynomials are;

This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.

In this given question, let's add the polynomials together.

[tex](3x^2+3x+5) + (7x^2-9x = 8\)\\3x^2 + 7x^2 + 3x-9x+5-8 =10x^2-6x-3[/tex]

The nth term is:

The 11th term is:

Step-by-step explanation:

first you convert 3 3/4 to an improper fraction

also convert 12/3to an improper fraction

3 3/4= 15/4

1 2/3=5/3

15/4 x5/3

=75/12

To mixed fraction it is 6 1/4

The red arc is named "minor arc EF" or simply "arc EF". This is the shortest distance from E to F along the curve.

The measure of arc EF is 68 degrees as this is the central angle that subtends this same arc.

23) The proof that ΔRSU is congruent to ΔTUS is from; SAS Congruency theorem.

18) The proof that ΔHOW and ΔNEW are congruent is from; SAS congruency theorem.

23) We are given a rectangle RSTU with diagonal US.

Now, we are told that;

UR is parallel to ST

∠R and ∠T are right angles

We can say that for ΔRSU and ΔTUS, that US is equal to itself in both cases by the reflexive property of congruence.

Now, since ∠R and ∠T are right angles, it means that UR is equal to ST.

Thus for the two triangles;

UR = ST

US = US

∠R = ∠T

There are two corresponding equal sides and one corresponding equal angle and as such, ΔRSU and ΔTUS are congruent by SAS congruency postulate.

18) We are given that;

H O = EN

HW = NW

Now, since HN intersects OE at W, then we can say that;

∠HWO = ∠NWE (Alternate angles)

There are two corresponding equal sides and one corresponding equal angle and as such, ΔHOW and ΔNEW are congruent by SAS congruency postulate.

Answer:

Step-by-step explanation:

Triangles ADB and CDB are congruent, so each is half the total area. The area of ADB is ...

  A = 1/2bh

  A = 1/2(DB)(1/2AC) = 1/4(DB)(AC)

The area of the kite is twice this value:

  A = 1/2(DB)(AC)

__

In order to use the formula derived in part 1, we need to know the length of BE. That can be found using the Pythagorean theorem:

  BE² +AE² = AB²

We know that AE = 1/2AC, so the desired dimension is ...

  BE = √(AB² -(1/4)AC²)

Then the area of the kite is ...

  area = 1/2(DB)(AC)

  area = (1/2)(AC)(ED +√(AB² -(1/4)AC²)

__

Given three sides of a triangle, the area of it can be found using Heron's formula. If you have not yet seen that in your geometry class, you can always use the Pythagorean theorem and some algebra.

As before, we need to know the lengths of the diagonals. One is given. The other can be found considering the Pythagorean relations:

  AD² = AE² +DE²

  AB² = AE² +BE²

  BE +DE = BD . . . . the sum of the horizontal diagonal lengths

Subtracting the second equation from the first gives ...

  AD² -AB² = DE² -BE²

Using the third to write an expression for DE, we get an equation for BE:

  AD² -AB² = (BD -BE)² -BE²

  AD² -AB² = BD² -2BD·BE +BE² -BE²

  (AB² +BD² -AD²)/(2BD) = BE

Substituting this into the original second equation, we can find AE, hence the area of the kite.

  AE² = AB² -((AB² +BD² -AD²)/(2BD))²

Which means the kite area is ...

  area = BD·AE = BD√(AB² -((AB² +BD² -AD²)/(2BD))²)

  area = (1/2)√(4·AB²·BD² -(AB² +BD² -AD²)²

This area formula demonstrates it is possible to find the area of the kite given the three lengths AB, BD, DA.

We have no doubt that the area formula of Part 3 can be rearranged to match Heron's formula. Here, we're interested in demonstrating area can be found.

Answer: yes

Step-by-step explanation:

Side JH and side HI are congruent and angle J and angle I are congruent so the two triangles are also congruent

The given two triangles EJH and EIH are congruent by the RHS congruency rule of two triangles.

Congruence of triangles:

If two or more triangles having same size and shape, then they are congruent to each other.

Every angle and sides are must be equal to each other and hence area is also equal.

How to show congruence in right angled triangles?

Here we have given that two triangles EJH and EIH, both are right angled triangles.

In any two right angled triangles having same hypotenuse and base side then they are congruent to each other by the RHS congruency

Here we have given side HJ ≅ side HI

∠EJH = ∠EIH = 90°

The common side EH is hypotenuse for both that is side EH = side EH

Therefore by RHS criteria these two triangles are congruent.

Answer:

GCF 35, 28 is 7

GCF 36, 27 is 9

Step-by-step explanation:

Greatest means biggest.

Common means same.

Factor means a number that goes evenly into the number. (3 goes into 27, so 3 is a factor of 27. 5 doesn't go evenly into 27, so 5 is not a factor of 27)

The biggest number that goes into both 35 and 28 is 7.

1, 5, 7, 35 are factors of 35.

1, 2, 4, 7, 14, 28 are factors of 28.

The biggest factor that's the same is the 7.

factors of 36:

Factors of 27:
