Can anyone help me with this math equation??

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:

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:

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:

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:

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:

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:

0.007105=1421/200000

Step-by-step explanation:

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

Answer:

x=10.4

Step-by-step explanation:

tan(60°)=18/x

tan(60°)x=18

x=18/tan(60°)

x=10.4

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:

  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:

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:

4.8

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

I think it's 3/7?

hope this helps

Answer:

A. x =2

Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16

Distribute

Add the numbers

Add 8 to both sides of the equation

Simplify

Add 12x to both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify -------> x=2

Step-by-step explanation:

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:

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
