Luke now takes 20 cards numbered 1 to 20. Show how the cards can
be paired to give an LCM of 60.

Answers

Answer 1

Answer:

Step-by-step explanation:

The pair members cannot be multiplied. Look at the last numbers that are prime starting with eleven

What are you going to pair these primes with

11 13 17 19

So they must be added (or maybe subtracted).

1 19

2 18

3 17

4 16

5 15

6 14

7 13

8 12

9 11

and 20 which no matter how you do this, there will be 1 card left over.

Each of them adds to 20 so the LCM is 20

Answer:

x = 120°

Step-by-step explanation:

this is a 7-sided polygon and the sum of the interior angles is (7-2)×180° = 900°

add all 7 angles together and set equal to 900

x + 150 + x - 20 + 140 + 120 + x + 20 + 130 = 900

combine 'like terms'

3x + 540 = 900

3x = 360

x = 120

The first term in an arithmetic sequence is 5. The fourth term in the sequence is −4. The tenth term
is −22.
Which function can be used to find the nth term of the arithmetic sequence?

Answers

Answer:

         aₙ = -3n + 8

Step-by-step explanation:

The nth term of an arithmetic sequence:  aₙ = a₁ + d(n - 1)

{d = common difference}

a₁ = 5

a₄ = 5 + d(4 - 1)

-4 = 5 + 3d

-4 - 5 = 3d

3d = -9

 d = -3

Therefore;

                  aₙ = 5 + (-3)(n - 1)

                   aₙ = -3n + 8

Check:  a₁₀ = 5 + (-3)(10 - 1) = 5 - 27 = - 22

The nth term of the sequence is Tn = 8 - 3n

How to determine the function of the nth term?

The given parameters are:

a = 5, first term

T4 = -4 --- the 4th term

T10 = -22 --- the 10th term

The nth term of an arithmetic sequence is:

Tn = a + (n - 1) * d

So, we  have:

T4 = a + (4 - 1) * d

Substitute known values

-4 = 5 +(4 -1) * d

This gives

-4 = 5 + 3d

Subtract 5 from both sides

3d = -9

Divide by 3

d = -3

Recall that:

Tn = a + (n - 1) * d

So, we have:

Tn = 5 + (n - 1) * -3

Expand

Tn = 5 + 3 - 3n

Solve

Tn = 8 - 3n

Hence, the nth term of the sequence is Tn = 8 - 3n

A line segment has endpoints S(-9,-4) and T(6,5). Point R lies on ST such that the ratio of SR to RT is 2:1. What are the coordinates of point R?

Answers

Answer:

Coordinates of R = (1,2)

Step-by-step explanation:

Let the coordinate of R be (x, y)

Since coordinates of S and T are S(-9,-4) and T(6,5). Then we can use the Formula for length of line from coordinates to find coordinates of R since SR/RT = 2/1

Thus; 1(S) = 2(T)

Coordinates of R = [(1(-9) + 2(6))/(1 + 2)], [(1(-4) + 2(5))/(1 + 2)

Coordinates of R = (3/3), (6/3)

Peter is making an "X marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides of 12 centimeters. He will make the "X" by stretching red ribbon diagonally from corner to corner.

Answers

Answer:

33.94 cms of ribbon

Step-by-step explanation:

Because you need two diagonals to form the x, therefore the amount  of ribbon needed is the sum of the distance of both diagonals.

When crossing the diagonal, a rectangular angle is formed, where the diagonal would be the hypotenuse, we know that the distance of the hypotenuse can be calculated by means of the legs, which we know its value (12):

d ^ 2 = a ^ 2 + b ^ 2

a = b = 12

d ^ 2 = 12 ^ 2 + 12 ^ 2

d ^ 2 = 288

d = 288 ^ (1/2)

d = 16.97

16.97 cm is what it measures, a diagonal, therefore tape is needed:

16.97 * 2 = 33.94

A total of 33.94 cms of ribbon is needed

Find the area of the trapezoids

Answers

Answer:

48 square units

Step-by-step explanation:

Each square on the grid is 2 units by 2 units.

Bases: AT = 8; RS = 4

Height: 8

area = (b1 + b2)h/2

area = (8 + 4)(8)/2

area = 48 square units

Answer:

The area of trapezoid is 48 sq units.

Step-by-step explanation:

According to the question,

➻ Trapezoid is consist of many square shapes. Each grid square equals 2 units. We need to find the area of trapezoid.

➻ To find area we need to find the length if base and height of trapezoid.

Calculate the square grids to find base and height. we get.

Base ; SR = 4 units and TA = 8units

Height = 8 units.

Finding the area of trapezoid.

We know that,

Area of trapezoid = ( Base1 + Base2 ) ×Height / 2

plug the values of both base and a height.

Area of trapezoid = ( 4 + 8 ) × 8 / 2

Add the numbers which are in bracket and multiply by 8.

Area of trapezoid = 12 × 8 / 2 = 96/2

Divide 96 by 2.

Area of trapezoid = 48 sq units.

Hence,

The area of trapezoid is 48 sq units.
