Find the distance between​ S(2.3,4.8) and​ T(6.4,7.9).

Step-by-step explanation:

Answer:

about 7.6

Step-by-step explanation:

I got the measure of the hypotenuse to be about 7.6 because I did the Pythagorean theorem.

a^2+b^2=c^2

The value of a is the first leg (7cm), and the value of b is the second leg (3cm).

So, 7^2+3^2=58. Next, I found the square root of 58. The square root of 58 is 7.615773106. This value rounded to the nearest tenth is 7.6.

In conclusion, the measure of the hypotenuse rounded to the nearest tenth is about 7.6.

Answer:

21/28

Step-by-step explanation:

Are there any answer choices?

-21 + 28x = 0

28x = 21

Divide by 28

x = 21/28

5x^2-11x-2x^3+6

Answer:

259.2

Step-by-step explanation:

multiply 18 x 8 x 1.8 to get 259.2cm

Answer:

2/3

Step-by-step explanation:

To find out what x is in this case, divide 3/4 by 9/8.

3/4 / 9/8

Dividing by a fraction is the same as multiplying it's inverse.

3/4 * 8/9

Cross cancellation (3 & 9 (GCF: 3); 4 & 8 (GCF: 4)

1/1 * 2/3

We can remove the 1/1.

2/3

2/3 is the value of x that will make 3/4 ÷ x = 9/8 true.

Answer:

Step-by-step explanation:

Equation

2x + 2 + 3x - 1 + x +4 = 29             Collect like terms on the left

6x + 5 = 29                                     Subtract 5 from both sides

6x = 29 - 5

6x = 24                                            Divide by 6

x = 24/6

x = 4

Length of the Sides.

2x + 2 = 2*4+2 = 10

3x - 1 = 3*4 - 1 = 12 - 1 = 11

x + 4 = 4 + 4 = 8

Type of Triangle

Scalene.

Answer:

I) 616

II) 4.53

Step-by-step explanation:

For the first one, just plug in 7 as R.

A = 4 x (22/7) x 7^2

A = 12.57142857 x 49

A = 616

For the second, one, put 452 4/7 as A.

452 4/7 also is 258.285

258.285 = 4 x (22/7) x r^2

258.285 = 12.57142857 x r^2

Divide both sides by 12.57142857

20.55372408 = r^2

Square root 20.55372408 for R.

4.533621519 = R

OR

4.53 = R

9514 1404 393

Answer:

  60

Step-by-step explanation:

Let x represent the number of members last summer. Then 90% more is 1.9x. We are told this is 114, so we have ...

  1.9x = 114

  x = 114/1.9 = 60

There were 60 members last summer.

Answer:

A) 2,500

Step-by-step explanation:

Soo.....

A1 = 4

A2 = 4*5 = 20

A3 = 20*5 = 100

A4 = 100*5 = 500

A5 = 500*5 = 2,500

Answer:

10 miles

Step-by-step explanation:

6 squared plus 8 squared = 100

the square root of 100 is 10 which is the hypotenuse of the route due to construction

Answer:

399.6 square miles

Step-by-step explanation:

The Area of a sector =

x/360° × πr²

r = 13.4 miles

x = 255°

Hence,

255°/360° × π × 13.4²

= 399.5739336 square miles

Approximately = 399.6 square miles

Answer:

399.6

Step-by-step explanation:

Answer:

2x²-3x-5

=2x²-3x-5

=2x²-5x+2x-5

=2x(x-5)+2(x-5)

=(x-5)(2x+2)

Answer:

(x + 1)(2x - 5)

Step-by-step explanation:

Assuming you require the expression factorised.

2x² - 3x - 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 5 = - 10 and sum = - 3

The factors are + 2 and - 5

Use these factors to split the x- term

2x² + 2x - 5x - 5 ( factor the first/second and third/fourth terms )

= 2x(x + 1) - 5(x + 1) ← factor out (x + 1) from each term

= (x + 1)(2x - 5) ← in factored form

Answer:

x=10.4

Step-by-step explanation:

tan(60°)=18/x

tan(60°)x=18

x=18/tan(60°)

x=10.4

Answer:

y² = 38x + 79

Step-by-step explanation:

Since directrix is the line x = -13, then it means x + 13 = 0

Focus is F(-3, 9).

Let A(x, y) be any point inside the plane having the focus and directrix.

Let MA be the perpendicular distance from A to the directrix and it means that A lies on parabola provided FA = MA.

Thus;

√[(x - (-3))² + (y - 9)²] = (x + 13)

Squaring both sides gives;

(x + 3)² + (y - 9)² = (x + 13)²

>> (x² + 6x + 9) + (y² - 18x + 81) = x² + 26x + 169

>> 6x + 9 + y² - 18x + 81 = 26x + 169

>> y² = 26x + 12x + 169 - 90

>> y² = 38x + 79

Answer:

x = -3 and x = 1

Step-by-step explanation:

first, square each side

12 - 8x = x² - 6x + 9

x² + 2x - 3 = 0

(x - 1)(x + 3) = 0

x = -3

x = 1

Step-by-step explanation:

m= 1-4/4-8 = -3/-4 = 3/4

y-1 = 3/4(x - 4)

y-1 = 3/4x -3

y = 3/4x -2

Answer:

4 miles

Step-by-step explanation:

Answer:

4.5 miles

Step-by-step explanation:

18 miles 3 hours = 6 miles/hour

6 x (3/4) = 4.5 miles

Answer:

144, 36

Step-by-step explanation:

you know that if you add the two angles it will equal 180 degrees. so add the two angles and make them equal to 180 and solve for x.

(4x+8) + (x+2)=180

5x+10=180

5x=180-10

5x=170

x=34

now replace x in each equation:

4(34)+8=144

34+2=36
