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:

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:

4.8

Step-by-step explanation:

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

Answer:

Each pentagon angle is 108 no matter what.

so 108*3=324

360-324=36

Answer=36

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:

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

Answer:

1: The initial value for option one is not charged

The rate of change for option 1 is $80/hr

Step-by-step explanation:

1. From the pricing options at the car dealership we have;

Option 1

Initial value = Not stated

Fee rate per hour of work = $80

Option 2

Standard fee = $100

Fee rate per hour of work = $400

The initial value for option one is not charged

The rate of change = The increase in payment for each increase in one hour of work = $80/hour

Mathematically, we have;

[tex]The \ rate \ of \ change = \dfrac{\Delta Payment}{\Delta Time} = \dfrac{\$80 - \$0}{1 \, h- 0 \, h} = \$ 80/hr[/tex]

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:

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

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

Simplify the expression

answer:  = -2x^2+6x+4

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

Answer:

21/28

Step-by-step explanation:

Are there any answer choices?

-21 + 28x = 0

28x = 21

Divide by 28

x = 21/28

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.

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:

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.
